ClipStack Privacy Policy
ClipStack keeps your clipboard history on your Mac. It has no account, no server of its own, and it collects nothing about you.
Last updated 20 August 2026 · applies to ClipStack for macOS,
za.co.airgro.clipstack
The short version
Everything ClipStack records stays in a folder on your Mac, encrypted with a key held in your Mac's Keychain. Nothing is uploaded. There is no analytics, no crash reporting, no advertising identifier and no third-party code of any kind in the application.
What we collect
Nothing. The developer receives no data from this app — not your clipboard, not usage statistics, not a device identifier, not an email address. There is no mechanism in the app for sending any of it.
What ClipStack stores, and where
When you copy something, ClipStack records it so you can find it again. That
record lives only in
~/Library/Containers/za.co.airgro.clipstack/Data/Library/Application Support/ClipStack
on your own Mac and includes:
- the copied text, image, or the path of a copied file;
- the name of the application you copied from, and the time;
- for pictures, any text ClipStack read inside them, so you can search for it;
- anything you add yourself — a rename, an edit, a drawing on a screenshot.
Copied files are referenced, not copied. If you copy a spreadsheet in the Finder, ClipStack stores where it is. It does not take a copy of the document, and the document stays where you left it.
How it is protected
The stored history is encrypted with a key generated on your Mac and held in the Keychain, marked so that it never leaves this device. A Time Machine backup copies the encrypted files and cannot copy that key, which is why restoring onto a different Mac cannot read them.
You can export an archive to move your history yourself. That archive is sealed with a passphrase you choose, using AES-GCM with a key derived by PBKDF2-HMAC-SHA256. Nobody can open it without that passphrase, including the developer.
When ClipStack uses the network
Two features, both listed here, and nothing else in the application makes a network request.
| Feature | What is sent | Default |
|---|---|---|
| Rich link previews | When you pause on a copied link, ClipStack asks that website for its title, site name and preview image. The website learns its own address was requested, as it would from any browser. Nothing about you or your clipboard is included. | Off |
| Update check | One request every six hours for a static file holding the latest build number. It carries no identifier, no query and no body. Nothing about you or your clipboard is included. | On |
Both can be switched off in ClipStack ▸ Settings. With both off, ClipStack makes no network requests at all.
Processing that happens on your Mac
ClipStack reads text inside screenshots so you can search for it, and can suggest a name for a clipping. Both use Apple frameworks that run entirely on your Mac — no image and no text is sent anywhere for this.
ClipStack also tries to notice when something you copied looks like a password, and hides it in the list. That judgement is made on your Mac from the text itself.
Permissions ClipStack asks for
- Accessibility. Used for one thing: to press ⌘V in the app you were using, so a clipping can be pasted for you. ClipStack does not read the contents of other applications' windows.
- Screen Recording, if you use the screenshot tool, so macOS can capture the screen.
- Touch ID or your login password, when you export your history or unlock a hidden clipping. This is checked by macOS; ClipStack is told yes or no and never sees your fingerprint or password.
Deleting your data
Delete a clipping from the list and it is gone from disk. To remove
everything, use Settings ▸ Storage, or drag ClipStack to
the Trash and delete its folder in
~/Library/Containers. Because nothing was ever sent anywhere, there
is nothing to request the deletion of.
Children
ClipStack is a productivity tool for general audiences. It does not knowingly collect information from anyone, of any age, because it does not collect information.
Changes to this policy
If ClipStack ever does something new with the network or with your data, this page will say so before that version ships, and the date at the top will change.
