DocsPers for Android Privacy Policy

By MerKuri Let Us Begin LLC · Effective

In short: DocsPers keeps your private files on your Android phone, encrypted. The developer cannot see, access, or collect your files. The app has no internet permission, no ads, no analytics, and no third-party tracking.

What the app handles

DocsPers is a private vault. It stores the files you choose to add: PDFs, pictures, videos and any other file type. It also stores the name you give each file, optional notes, the folders you make, the file size, and the date you added it.

How your files are protected

Encrypted before they are saved. Each file is encrypted on your phone with AES-256 before it is stored. Your file names, notes and folders are kept in a separate encrypted index. Only the file size and the date added are readable without the key.

The key stays on your phone. The encryption key is random and is protected by a key held in the Android Keystore (secure hardware on most phones), which cannot be copied out of the phone. The developer cannot read it.

Not copied to the cloud automatically. DocsPers switches off Android's automatic cloud backup and device-to-device transfer for its data, because the key could not travel with it. Your files live only on this phone unless you make an encrypted backup (below).

If you uninstall DocsPers, reset your phone, or lose it, the key is gone and the files cannot be opened by anyone, including the developer. Keep an encrypted backup and remember its password.

Where your data is stored

On your device only. Files are stored in the app's private storage, which other apps cannot read.

Nothing is sent to the developer or to any other server. DocsPers does not declare the internet permission and contains no analytics, advertising, or third-party software that collects data.

Lock and screen protection (your choices)

Lock: you can require your fingerprint, face or screen lock (PIN, pattern or password) to open DocsPers. It is on by default. Your fingerprint, face and screen lock data stay inside Android: DocsPers is only told whether the check passed. You choose how long the app waits in the background before it locks again, or you can turn the lock off in Settings after unlocking.

Block screenshots and screen recording: on by default. When on, Android shows a black screen if anyone tries to capture DocsPers. You can turn it off in Settings. The picture shown in the recent-apps list is always hidden.

Previews and sharing

When you preview a file or share a copy, DocsPers decrypts it into a temporary file in the app's private cache. These temporary copies are removed when you close the preview and the next time the app starts. Once you send a copy to another app or person, that app's or person's privacy practices apply to the copy they receive.

Encrypted backup

You can save all your files into one backup file, locked with a password you choose (at least 10 characters).

The file is encrypted on your phone before it is saved, using a key made from your password. Only your password can open it.

A lost password cannot be recovered. Without it, nobody can open the backup, including the developer.

You decide where it goes: your phone's storage, Google Drive, a USB drive or another place you pick in Android's file picker. DocsPers does not upload it anywhere itself, and the developer never receives it.

Restoring adds files that are missing and never changes or removes files that are already in the app.

Copies of the backup file that you save elsewhere are yours to keep or delete.

What the developer collects

Nothing. The developer does not operate any server that receives your data, and the app contains no analytics, advertising, or third-party tracking. Your files are never sold, shared, or used for advertising, marketing, or data mining.

If you allow Android or Google Play to share crash and diagnostic reports with app developers, the developer may receive anonymized reports. These do not contain your files.

Permissions

Biometric / screen lock (USE_BIOMETRIC, USE_FINGERPRINT): to unlock the app. These are ordinary permissions Android grants without a prompt.

Photos and Files: DocsPers does not ask for access to your whole photo library or storage. It only receives the pictures, videos and files you pick yourself in Android's pickers.

No internet, location, contacts, camera or microphone permissions.

Deleting your data

Individual files: delete them in the app.

Everything: uninstall DocsPers or use Settings → Apps → DocsPers → Storage → Clear storage. This removes the vault and its key.

Backup files you saved elsewhere: delete them where you saved them.

Because the developer never receives your data, there is nothing held by the developer to request deletion of.

Children

DocsPers is not directed to children under 13 and does not knowingly collect any data from them.
