Fold was previously called Booker. This policy covers the app under both names.
Last updated: 29 September 2026
Fold is a native macOS app that helps you organize your bookmarks locally on your own Mac. Fold is local-first: your data lives in a database on your device. There is no Fold account, and the Fold app itself does not run analytics or send telemetry. Fold's website counts, in total, some of the requests it already receives, such as update checks and downloads (see What the website counts).
Fold can import bookmarks you already have: from your browsers, from apps such as Eagle, and, if you choose to connect it, from X. Reading Safari's bookmarks needs Full Disk Access, which Fold asks you to grant in System Settings. Once you've set Fold up, each time it starts it imports bookmarks from every browser it can read on your Mac, and while it's running it notices when those bookmarks change and imports the changes. It then visits new pages, as described under Enriching bookmarks. Fold reads this data. It doesn't post, edit or delete anything in your browsers, those apps or X.
When you choose Scan Library in Cleanup, Fold also reads the browsing history of Chrome-family browsers (such as Chrome, Brave, Edge and Vivaldi) and Firefox on your Mac, to see how often you've visited the pages you saved. It keeps only the visit count and last visit date for each saved bookmark, in its database on your Mac, and doesn't send them anywhere.
If you turn on Fold's clipboard shelf, Fold keeps things you copy (links, images and text), and the app that was in front when you copied each one, on your Mac. It asks before it starts. It skips copies that an app marks as concealed or transient, as many password managers do, but it can't recognize a secret that an app doesn't mark. You can clear your clipboard history in Settings at any time.
If you want Paste Anywhere to paste a clip straight into another app, Fold asks for Accessibility access in System Settings and uses it to press ⌘V for you. Without that access, Fold puts the clip on your clipboard and you paste it yourself.
Pinterest import is turned off in the current version of Fold.
An earlier version of Fold let you import from Pinterest by signing in to
pinterest.com inside Fold's built-in browser. Fold then scrolled
through your boards and read your pins from the pages Pinterest's own site loaded
there. If you signed in to Pinterest that way, Fold's built-in browser keeps that
sign-in the same way it keeps your X sign-in (see
Where your data lives). That version also had a test option
that imported pins through Pinterest's API with an access token you pasted. Fold
used the token to fetch your pins and didn't save it.
Imported pins are copied into your local library on your Mac, where boards become collections. Your pins and boards are stored on your device unless you share a collection that contains them (see Shared collections). Fold still contacts other servers for them, for example to load their images (see Network activity). Fold doesn't write to Pinterest.
A future version may use Pinterest's official OAuth instead. With OAuth, Fold asks
Pinterest for read-only access to your own boards and pins (the
boards:read and pins:read permissions), using the sign-in
helper described below.
Fold's code for signing in with Pinterest's official OAuth hasn't been turned on
in any version of Fold. If it is, it works like this. A small, stateless helper
hosted at getbooker.vercel.app holds Fold's Pinterest app secret, so
the app on your Mac doesn't have to. The helper does three standard things:
So your authorization code and tokens pass through the helper. Its code doesn't store or log your authorization codes, access tokens or refresh tokens. Vercel, which hosts it, may keep standard request logs (see Network activity), and the authorization code is part of the redirect's web address. Your boards and pins don't pass through the helper: the Fold app talks to Pinterest directly to fetch them, and keeps your tokens in your Keychain.
Because Pinterest import is turned off in the current version, Fold doesn't use this helper today.
Fold stores everything it imports in a local database on your Mac, and uploads
your bookmarks to Fold's sharing service only if you share a collection (see
Shared collections). To fill in titles, previews and icons,
Fold still contacts the sites you saved and sends their host names to Google's icon
service, and to DuckDuckGo's when Google has no icon, with the exceptions for hosts on
your own network described under Site icons (see
Network activity). Fold keeps
its library in its data folder, ~/Library/Application Support/Booker.
A few things, such as settings and the Keychain items described under
Fold Pro, are stored elsewhere on your Mac. If you turn on
"Include Bookmarks in Spotlight", Fold also adds your saved bookmarks to Spotlight's
index on your Mac: their titles, links, domains, sources and tags, a summary,
description or site name (or your note when none of those exists), a thumbnail of a
preview stored on your Mac, and up to about 4,000 characters of each saved page's
text.
In every version, whatever your plan, Fold keeps a diagnostics log.
It writes the log to diagnostics.log in Fold's data folder and to macOS's
system log, and doesn't send either of them anywhere. They leave your Mac if you send
someone a diagnostics report or your Mac's system logs. Deleting Fold's data folder
removes diagnostics.log but not the lines already in macOS's system
log.
The log's lines can include links to pages you saved, the link IDs of your shared collections (each one opens that collection), your backup folder's location, the names of your browser profiles, the names of apps you use Paste Anywhere with, and file paths that can include your Mac account name. A diagnostics report, which you can copy or save from Fold, contains the recent part of that log, plus Fold's and macOS's versions, your Mac's processor type, how many bookmarks and profiles each source has, and how many bookmarks, collections and topics you have. Read a diagnostics report before you send it. Versions released before 14 September 2026 (before 1.4.8) also logged the tags Fold suggested for bookmarks you opened, and those lines can still be in the log.
When you delete a bookmark, Fold moves it to its Trash and keeps it on your Mac, with its notes, tags and saved page text, so a later import doesn't bring it back. It's erased when Fold starts and finds it has been in the Trash longer than the Empty trash setting in Settings ▸ Storage allows (that setting is Never by default), when you use Remove All… for X or Pinterest in Fold's settings, or when you delete Fold's data folder. Erasing a bookmark also erases Fold's record that you deleted it. If it's still in your browser or still bookmarked on X, Fold imports it again: browser bookmarks at the next import, and X bookmarks at the next check unless you've turned off "Keep X bookmarks up to date". That includes X posts you had deleted in Fold before. To keep them out, remove them in the browser or on X first, or turn off that setting before you use Remove All….
Deleting the bookmarks you can see, clearing your clipboard history and withdrawing a shared collection are included on every plan, and Fold doesn't delete your data to enforce a plan. To remove Fold's library from your Mac, quit Fold and delete its data folder.
Deleting the data folder doesn't remove what Fold keeps elsewhere on your Mac:
~/Library/Caches/models.To see whether plans are active in your copy of Fold, open Settings ▸ Plan. If it says "Plans aren't active in this version of Fold. Everything is included.", none of the plan limits, the trial or the license checks on this page apply to you, and everything is included, including export and backups. Where plans are active:
The Fold app has no analytics, crash reporting or telemetry. It connects to the internet for the things listed below.
Every connection shows the server you connect to your IP address. Fold's own
services, at getfold.design (shared collections and Fold Pro) and
getbooker.vercel.app (updates and the Pinterest sign-in helper), are
hosted by Vercel. Vercel sees the IP address and standard headers of every request
to them. Those headers can include the app's name and version, your macOS version
and your preferred languages. Vercel may keep this information in request logs,
which Fold's developer can view. How long those logs are kept depends on Vercel and
on the plan Fold's developer has with Vercel. The sharing service keeps its database
(shared collections and their items, comments, view counts, the abuse counts
described under Shared collections and the website's usage
counts described under What the website counts) with Neon, a database
hosting provider, and stores uploaded pictures and pages in Vercel Blob, Vercel's
file storage.
Enriching bookmarks. In the background (when Fold starts, after
an import and when you add a link), Fold visits web pages you've saved, directly and
without your sign-ins or any stored cookies (a cookie a site sets is kept only in memory
while Fold is fetching), to read their title, description, preview image and text. It
identifies itself the way Safari does. Later it revisits pages that still have no
preview image. For saved X posts, it follows the links in the post (such as
t.co short links) one step at a time, identifying itself as Fold, and
then visits the page they lead to. For links on your clipboard shelf, it visits the
page to get a title and preview image.
Site icons. Fold doesn't get site icons from the sites
themselves. It sends the site's host name (for example example.com or
docs.example.com, not the full link) to Google's favicon service, and to
DuckDuckGo's if Google has no icon. This covers sites in your library, on your clipboard
shelf and in Discover, and the icons for Fold's sources. Fold keeps the results on your
Mac.
Versions of Fold released after 17 September 2026 don't send a host that can only be on
your own network: an IP address, a one-word name such as printer, or a name
ending in .local, .lan, .internal,
.home.arpa or a similar private-use ending. They send any other name only
after your Mac's DNS says it points to public internet addresses, so a company intranet
name that points to a private address isn't sent either. Earlier versions send those
host names too, including names such as nas.local and addresses such as
192.168.1.1.
Images and videos. Fold downloads preview images from the servers that host them, including X's media servers, and keeps them on your Mac. It does this as you browse and, while Visual Search is on (it is by default), in the background when Fold starts and after imports, working through your whole library so it can index what the pictures look like. Videos play from the servers that host them. When you import X posts, Fold downloads each post's lead image and the author's picture from X's media servers.
Frames from X and Pinterest videos. When you open a saved X or Pinterest video, Fold reads a few small frames from it for the frames bar, and Save Frame and the frame steps take their pictures from the video as it plays. Once you have watched the video for a moment, stepped through it or saved a frame, Fold also downloads a temporary copy of it in the background so frames can be saved exactly. It does this on its own only when the server says the video is 200 MB or smaller, and never while your Mac is in Low Data Mode or on a Personal Hotspot or cellular connection. Otherwise Fold copies a video only when you ask: when you choose Get Exact Frames, or when you step through or save a frame from a video that won't play from its server, because the copy is then the only way to show that frame. The copy is downloaded without cookies and only from public internet addresses, is limited to 1 GB, is deleted when you close the item, move to another item or quit Fold, and is never added to your library, an export or a backup.
X. If you import from X, you sign in to X inside Fold's built-in
browser, and Fold reads your X bookmarks from X using that sign-in. Fold uses your X
sign-in with X's own servers (x.com and twitter.com) and
doesn't send it anywhere else. After your first import, unless you turn off "Keep X
bookmarks up to date" in Settings, Fold checks X for new bookmarks when it starts,
every 15 minutes while it's running, and when you switch to Fold (at most once a
minute).
Updates. About once a day, and when you choose Check for
Updates…, Fold asks getbooker.vercel.app whether there is a new
version, and downloads it from there when you update. The check sends no system
profile. Its request identifies Fold's version and the updater's. Fold's website
counts these checks and update downloads per day and per Fold version (see
What the website counts).
Shared collections and Fold Pro. If you have shared collections,
Fold checks getfold.design for new comments (see
Shared collections). Where plans are active, Fold talks to its
license service at getfold.design (see
Fold Pro, purchases and license keys).
Pinterest. Pinterest import is turned off in the current version, so Fold doesn't import from Pinterest or use the sign-in helper. If your library has pins imported by an earlier version, their images may still load from Pinterest's servers.
When you ask. Fold also goes online when you:
Links you open in your web browser, including Polar's checkout and customer portal, are handled by that browser, not by Fold.
AI features. Fold's AI features, such as tagging, summaries, search and Ask, run on your Mac using Apple's on-device models, models that come with Fold, and the vision model if you download it. Nothing goes to a cloud AI service unless you turn on Cloud Assist.
Cloud Assist (optional). Off unless you turn it on, and the same on every plan. When it's on, for each feature you enable, Fold sends a few fields of the items it is organising — the title, the website's domain, where it was saved from, and a short excerpt with email addresses, phone numbers and every number of four or more digits removed (plus an image description, only if you turn that on) — and, for pictures saved from X or web pages, the picture itself — together with the names of your existing tags or collections it is choosing among. These go to Fold's helper at getfold.design, which passes them to TypeSafe AI in the United States and returns the answers. What Fold sends is processed by TypeSafe AI under its terms; TypeSafe may keep it and says it does not train on it. Nothing is sent unless you turn Cloud Assist on. Fold's helper doesn't store or log the content (it logs only error codes and which model answered; Vercel, which hosts it, keeps its usual request logs, which include your network address).
There is no account. The first time Cloud Assist is used, the helper gives this Mac an anonymous, random install code; it isn't tied to you, your Mac or your address, and it is used only to count fair use. Those counts are kept for two days under keyed codes (of the install code and of your network's address) that can't be read back without the helper's secret key. Fair use is shared by everyone on the same network: behind one office or public Wi-Fi address, a few busy Macs can use up that network's share for the day, and Cloud Assist then waits until the next day. The code is deleted from your Mac when you turn Cloud Assist off or clear its history, so turning it on again starts afresh — and asks for your consent again.
Fold never sends your notes, clipboard items, files you added or imported from a folder, browsing history, the words you type to search or filter in ⌘K, the questions you ask in Ask, anything from Eagle or Pinterest, or items from sites on private networks (names such as .local or .corp, and private IP addresses). You can also keep a browser profile or a collection at home in Settings. Cloud Assist picks tags among the ones you already have — it never makes up a new one — and suggests which of your existing collections an item belongs in. Tags it is very sure of are added automatically, marked as Cloud Assist's and in batches you can undo; collection suggestions wait for you to accept them. You can turn Cloud Assist off, remove everything it added or suggested, or clear its history in Settings ▸ Intelligence at any time.
The Fold app sends nothing extra for this. Fold's website counts, in total, some of the requests it already receives:
Requests from search engines, link previews and other automated tools aren't counted, and a download that resumes after an interruption is counted once.
To count each Mac or visitor once per day and once per week, the website makes a one-way code (HMAC-SHA-256) from the request's IP address (for an IPv6 address, only its first half, which names the network) and its app or browser details, with a key that changes every day (for the daily count) and every week (for the weekly count). Those keys are made from a secret the service holds. Without it, the IP address can't be worked out from a code, and codes from different days or weeks can't be matched with each other; whoever holds the secret could still test guesses, such as every possible IPv4 address, against a code while it's kept. Each code is kept with the day it's for (or the first day of its week), not the time it was made, and is deleted 8 days after that day, the next time the website counts a request. After that, all that's kept is the totals: for each day, and for update checks and update downloads each Fold version, how many requests there were and how many different Macs or visitors made them.
The website doesn't use cookies for this, and doesn't store IP addresses, browser details or anything that identifies your Mac. The totals are kept in the sharing service's database with Neon (see Network activity), and only Fold's developer can see them. Vercel's own request logs, described under Network activity, are separate from these counts.
If you choose Share Collection…, Fold publishes that collection to Fold's sharing
service at getfold.design and gives you a link. Anyone with the link can
view the collection and comment on it. Fold turns comments on for every collection
it shares.
A shared collection is a copy of the collection as it was when you shared it or last pressed Update. Deleting a bookmark in Fold, or removing it from the collection, doesn't remove it from the shared collection until you press Update in the share sheet or stop sharing.
Fold uploads the collection's title and, for each item, its title, link, domain, type and a preview image, including pictures that exist only on your Mac. With "Let people read the pages" on, which it is by default, Fold also uploads a copy of up to 200 of the shared pages, with scripts removed, and uses a picture of the top of the page for items that have no preview image. Your notes and tags are uploaded only if you turn on "Include my notes and tags". Fold doesn't share links to files on your Mac.
While publishing, your Mac also visits each shared link, signed out, to capture pages and to check whether they can be shown inside the shared collection. It also downloads the preview images again from the sites that host them.
People viewing a shared collection can comment under a name they type (or "Someone"). The service stores that name, the comment and the part of the page it points to, and the viewer's browser remembers the name they typed. The service counts views and records when the collection was last viewed. Its database doesn't store viewers' IP addresses or browser details, but Vercel sees them (see Network activity). When a viewer opens an item from a site that allows it, the shared collection shows the live site in a frame by default, so the viewer's browser connects directly to that site, which sees their IP address and browser details.
To limit abuse, the service counts requests to create a shared collection from each IP address in each clock hour. It stores each count under a keyed hash (HMAC-SHA-256) of the address, made with a secret key the service holds, not under the address itself. Without that key, the address can't be worked out from the hash; whoever holds the key could still work out an IPv4 address by testing every possible one. The service deletes each count once its hour has ended, the next time it records a count or when its daily cleanup runs, so a count is kept for at most about a day after its hour ends.
When you reply to a comment from Fold, your reply is posted under your Mac user account's full name (or "Someone" if it has none).
While you have shared collections, Fold checks the service for new comments when it starts and when you switch to it (at most every 5 minutes). It fetches view counts when you open a shared collection in Fold. When you open a comment, Fold downloads the page or picture the comment points to from the service.
Your Mac keeps a secret for each shared collection, and the service accepts changes or withdrawal only with that secret. Fold's developer can also remove a shared collection, for example to deal with abuse.
When you stop sharing a collection, or delete it, Fold asks the service to withdraw it. If that fails, Fold tries again later while it's running, waiting up to six hours between attempts. Once a collection is withdrawn, its link no longer shows it, and the service deletes its uploaded files, unless another live shared collection uses the same file. Cached copies of pictures and pages may stay downloadable for up to a day (up to a year for pictures and pages first shared before 6 September 2026), and anyone who already saved them keeps their copies. The collection's title, its list of items (each item's title, link and domain, plus your notes and tags if you included them) and its comments, including deleted comments, stay in the service's database, hosted by Neon. Email us their link if you'd like them erased. Fold forgets a collection's link once it's withdrawn, so keep the link if you might ask us later.
When preparing to delete files from the service's storage that no live shared collection used any more, Fold's developer has first downloaded copies of them, and has saved a copy of a collection's comments, including deleted ones, with the collection's title and the title and link of each item commented on, before it was withdrawn. These copies are kept on the developer's computer, outside the service, and may be made again. Email us if you'd like any copies of your content erased.
Fold Pro is a paid subscription, sold monthly or annually. If Settings ▸ Plan says "Plans aren't active in this version of Fold. Everything is included.", Fold makes no purchase or license requests and keeps no trial or license records. Of this section, only the clipboard rule for license keys and what deleting Fold leaves behind apply to that version.
Where plans are active, every copy of Fold asks Fold's license service at
getfold.design whether purchases are available, and for the current
checkout and portal links, whether or not you've bought Fold Pro. It does this when
Fold starts and when you switch to Fold (at most every 4 hours). It also does it
before you activate a key, if Fold doesn't yet know that purchases are available, and
before it opens the customer portal, if it doesn't have the portal link yet. The request
carries no license key, device identifier or Mac name. Like every request, it shows
the service your IP address and standard headers (see
Network activity).
Where plans are active, Fold starts a 14-day trial the first time you open it. If
your Mac already had a Fold library before plans were introduced, Fold records that
in entitlement.json in its data folder instead of starting a trial. That
record isn't kept in your Keychain, so if you delete the data folder, Fold treats the
Mac as a new install. The trial needs no account and no payment details, and
starting or tracking it sends nothing over the network. (Fold still checks whether
purchases are available, as described above.)
The trial's start and end dates are kept on your Mac, in Fold's data folder
(entitlement.json) and in your Keychain (an item named
app.getfold.entitlement.trial). Fold doesn't send them anywhere. The
Keychain item stays if you delete Fold or its data folder, so reinstalling doesn't
start a new trial. entitlement.json also records which trial reminders
you've seen, whether your plan has paused clipboard capture, and the latest time
Fold has seen. That last one means setting your Mac's clock back doesn't reopen a
trial Fold has already seen end, as long as that file is kept.
When you choose a plan, Fold opens Polar's checkout in your web browser. Every copy of Fold gets the same checkout links, and Fold adds nothing to them that identifies you or your Mac. Checkout then happens between your browser and Polar.
Polar sells Fold Pro to you as the merchant of record: it is the reseller that takes your payment, charges any sales tax or VAT, and sends your receipts and invoices, including by email. Your purchase is made under Polar's Buyer Terms. Polar's Privacy Policy describes the personal data Polar collects and who processes your card details.
Fold's app and Fold's license service don't receive your card details. Fold's developer can see details of your purchase in Polar, such as your name, the email address you bought with, the billing address and any tax ID you gave at checkout, and the label of the Mac your key is active on (for example "Fold on Studio Mac"). We use them to help with your purchase and license. Fold's app doesn't receive them.
When you finish or leave checkout, your browser is taken back to a page on
getfold.design, and a link back to Fold from Polar's customer portal may
lead to a similar page. After a purchase, that page's address includes Polar's
checkout ID. These pages run no scripts and read nothing from their address, but like
any web page, the visit reaches Vercel, which hosts them, with your IP address and
browser details. Vercel's request logs can record the page's address, including the
checkout ID, together with your IP address, so Fold's developer could connect that
visit to your purchase. Their Open Fold button asks Fold to check your license again if
you've entered a key (see Checks after activation).
After you buy, Polar gives you a license key. You can see and copy it in Polar's customer portal, polar.sh/getfold/portal. There you can also download invoices and receipts, update your payment method, cancel your subscription, and release the Mac your key is active on. You sign in to the portal with the email address you bought with, and Polar emails you a one-time code. The Manage Subscription button in Settings ▸ Plan, and the portal links next to the key field, open this portal in your browser and add nothing that identifies you.
The key field hides what you type. Before sending anything, Fold checks on your Mac that what you entered could be a key. If it contains something shaped like a license key, Fold sends just that part. Otherwise Fold sends what you entered as long as it is no more than 128 characters with no spaces, so make sure you've pasted your key and not something else.
Fold sends your key, a device identifier and your Mac's name to Fold's license
service at getfold.design, over HTTPS and without cookies. Like any
request, it also carries your IP address and standard headers.
The device identifier is a 40-character code that Fold works out on your Mac. It runs your Mac's hardware UUID, together with a fixed Fold-specific string, through a one-way hash (SHA-256). Fold doesn't send the hardware UUID itself. The code ties your license to one Mac: later checks must carry the same code. The code isn't secret. On a Mac that reports a hardware UUID, the same Mac normally produces the same code, even if you reinstall Fold, and anyone who already knows that UUID could work it out. If your Mac doesn't report a hardware UUID, Fold creates a random value once, keeps it in your Keychain and hashes that instead.
Your Mac's name (the one set in System Settings, cut to 64 characters) is sent only when you activate. It's used to label the activation, for example "Fold on Studio Mac", so the Mac that holds your key can be recognized. Neither the app nor Fold's license service stores the name, but it becomes part of the activation's label, which Polar keeps with your license and which Fold's developer can see there. Mac names often include a first name. If you'd rather not share yours, rename your Mac before activating.
Fold's license service passes the key, the label ("Fold on" followed by your Mac's name, or "Fold on a Mac" if it has none) and the device identifier to Polar. Polar stores the activation and its label with your license key, and checks later requests against the device identifier. These requests reach Polar from Fold's server, and the service doesn't pass on your IP address, so Polar doesn't see your IP address for them. Each key can be active on one Mac at a time.
Once your key is active, Fold's license service gives Fold a signed license record that is valid for a few days. To renew it, Fold sends a check containing the key, the activation ID and the device identifier. The check doesn't include your Mac's name. The service passes the same three things to Polar to confirm the activation.
Fold sends a check automatically when the record is missing, doesn't verify, or has a day or less left. In regular use, that's about every two days. If an automatic check doesn't renew the record, Fold skips automatic checks for the next 15 minutes.
If a key is stored, Fold also sends a check each time you choose Check Again in Settings ▸ Plan, when you enter the key that is already on this Mac, and when you click Open Fold on a page you see after checkout. While your record has more than a day left, Check Again and Open Fold send at most one check a minute; after that, each press sends a check.
If Fold can't reach the service, because you're offline or the service or Polar is unavailable, Fold keeps honoring your last signed record until it runs out, and then for 7 more days. After that, this Mac stops getting Fold Pro until a check succeeds. A failed check doesn't remove your license record. An answer that your key is invalid or no longer active does remove it, which ends Fold Pro on this Mac. Your key and activation ID stay in your Keychain until you deactivate this Mac or replace the key.
License requests don't use a database. The license service doesn't store your key, device identifier, Mac name or activation. Polar's replies can include the name and email address on the purchase. The service ignores them, and doesn't keep them or pass them on to the app.
Fold's code writes no log line for a successful license request. When a request is turned down after the service has asked Polar about it, or the service can't complete it, the service logs the kind of request, the reason, and the first 8 characters of a SHA-256 hash of your key. Anyone who has your key could match that fingerprint to it. These log lines don't include the key itself, your device identifier, your Mac's name, the activation ID or your IP address.
The service runs on Vercel. Vercel receives each request with your IP address and standard headers, and may keep them, along with the log lines above, in logs that Fold's developer can view (see Network activity).
Your license key and its activation ID are kept in your Keychain, in an item named
app.getfold.license. On a Mac that doesn't report a hardware UUID, that
item also holds the random value used for the device identifier. Fold shows only the
last four characters of the key.
entitlement.json in Fold's data folder holds the latest signed license
record, which contains:
The record doesn't contain the key. Fold also remembers whether you last chose monthly or annual billing.
Fold's diagnostics log (see Where your data lives) also notes licensing events, such as "activated on this Mac", but not your key, activation ID, device identifier, Mac name or checkout and portal links.
Whether or not plans are active, the clipboard shelf skips any copy of about 500 characters or fewer that contains a license key in the format Fold's keys use, and anything an app marks as concealed or transient.
Where plans are active, clipboard capture stops completely while Fold is sending your key to be activated, and while Fold's upgrade window stays open after you've opened checkout from it. Nothing you copy during that time is picked up afterwards. At other times, including while you copy a key into Enter License Key… in Settings ▸ Plan, only the rule above applies.
The Paste button next to the key field reads your clipboard only when you click it, and ignores a clipboard marked concealed or transient. A key inside a longer piece of copied text can still be captured. If that happens, you can clear your clipboard history in Settings.
When you choose Deactivate This Mac… in Settings ▸ Plan and confirm, Fold sends the key and activation ID to the service, with no device identifier or Mac name. The service asks Polar to release the activation. Fold then removes the key and activation ID from your Keychain and the license record from its data folder. It does the same if the service answers that there's nothing left to release. If the request fails for another reason, such as being offline, Fold keeps everything and you can try again. On a Mac that doesn't report a hardware UUID, the random value used for the device identifier stays in the Keychain.
Releasing an activation ends it, though Polar may keep a record of it. Deactivating doesn't cancel your subscription; you can cancel in Polar's customer portal. Fold also asks the service to release an activation by itself when you enter a different key (after the new key works, it releases the old key's activation), and when a new activation's record doesn't verify on this Mac.
Deleting Fold or its data doesn't cancel your subscription or release your key's
activation. To release it, deactivate this Mac in Settings ▸ Plan before you delete
Fold, or release it later in Polar's customer portal, where you can also find your key
and cancel. Deleting the app doesn't remove Fold's data folder or its Keychain items
(app.getfold.license and app.getfold.entitlement.trial). You
can delete the Keychain items yourself in Keychain Access.
Deleting the app also leaves behind the sign-ins, cookies and other website data kept
by Fold's built-in browser, the vision model in ~/Library/Caches/models,
Fold's settings and your backups, and Fold's Spotlight entries can stay (see
Where your data lives). Before you delete Fold, turn off "Include
Bookmarks in Spotlight" so Fold removes its Spotlight entries.
Your shared collections also stay online. If you don't want them to, stop sharing them in Fold, while you're online, before you delete Fold (see Shared collections). Once Fold's data folder is deleted, Fold can't withdraw them, but Fold's developer can remove them if you email us their links.
