Unpack — Privacy Policy
Last updated: August 12, 2026
Unpack is built to work entirely on your device.
What we collect: nothing.
Unpack has no accounts, no sign-in, no analytics, no crash reporting, and no advertising SDKs.
Unpack cannot reach the internet at all
This is stronger than a promise not to. Unpack does not declare Android's
INTERNET permission, and an Android app without that permission cannot open a
network connection of any kind — not to us, not to anyone. You can verify this yourself
on your own device: open Android Settings, then Apps, then Unpack, then Permissions.
The app's build enforces it too. Every build checks the app's complete, final permission list against a fixed set, and fails if anything outside that set appears — including any permission arriving through a third-party library.
Files you open
Unpack reads and writes files on your device, which is its entire purpose. Those files are never uploaded, copied off the device, or indexed anywhere, because the app has no way to send anything anywhere.
All files access
On Android 11 and later, Unpack may ask for the "All files access" permission. It is never requested on first run, and the app works without it — extracting to your Downloads folder needs no permission at all. It is used for two things: extracting to a folder you choose anywhere on your storage, and measuring what is using space across the whole device. Without it, Android hides other apps' files from Unpack, so a storage measurement would be silently incomplete; Unpack refuses to show one rather than showing a wrong one. You can revoke the permission at any time in system settings.
Opening a file in another app
Unpack shows images and plain text itself. For anything else, tapping a file hands it to an app you already have — a video player, a PDF reader, and so on. Once a file is handed to another app, what that app does with it is governed by that app, not by Unpack. This is the one thing the rest of this page does not cover, and we would rather say so plainly.
What is stored on your device
Unpack saves three small preferences, and nothing else:
- which destination you last extracted to, as a category such as "Downloads" — never a path
- how you like file lists sorted
- the date of your last storage scan
No file names, no folder paths, and no passwords are ever written to disk. Passwords you type for encrypted archives are held in memory only and are gone when the app closes.
Backups
Android may back up app data to your Google account. Unpack limits this to the three preferences above. Copies of archives you open are explicitly excluded from both cloud backup and device-to-device transfer.
Data sharing
We do not share data with anyone, because we do not collect any.
Children
Unpack does not collect personal information from anyone, including children.
Changes
If this policy ever changes, the updated version will be posted at this URL with a new date.

Unpack is published by Cardwell Software LLC. Deleting files is permanent; Unpack asks before deleting anything and always keeps one copy of each set when removing duplicates, but it cannot recover a file once it is gone.
