Privacy policy

Last updated: 12 November 2026

Summary

Cadrivault does not collect, sell or share personal data. It has no account and no servers, and the app does not request permission to access the internet. Your documents, images, recognised text, search index and settings are stored only on your device, unless you choose to export, share or back them up.

Who we are

Cadrivault is an Android app developed by FSZ Dev (“we”). Contact: membros96_mapeadores@icloud.com.

What the app stores on your device

• Documents: the photos you capture or import, cropped and filtered pages, PDFs and the copies created by edits.
• Recognised text and search index: created on the device so you can copy text and search inside documents.
• Organization: names, folders, tags, favourites and dates.
• Settings and presets: for example default filter, watermark presets, language and theme.
• Purchase status: whether Cadrivault Pro is active, as reported by Google Play.

This information never leaves your device on its own, and we never receive it.

Camera and files

The camera is used only while you scan, and images are processed on the device. Files are imported or exported only through the system file picker or share sheet, by your action. The app does not read your photo gallery or other files on its own.

Vault, app lock and backup

Files in the vault, including their thumbnails and recognised text, are encrypted with keys protected by the Android Keystore. App lock uses your phone's screen lock or biometrics; Cadrivault never sees your fingerprint, face data or PIN. Android's automatic cloud backup is turned off for Cadrivault; backups are files you create and keep yourself, optionally protected by a password. Vault documents are not included in backups, because their key belongs to the phone.

On-device AI (optional)

On supported phones you can turn on the AI built into Android (Gemini Nano through AICore) to fix recognised text, summarise a document, extract fields from receipts and suggest file names. It is off by default, runs in a system service on the phone, and every suggestion is shown for your review first. The model itself is installed and updated by Android, not by Cadrivault.

Purchases

Subscriptions and the lifetime purchase are processed by Google Play under Google's terms and privacy policy. Cadrivault receives only the purchase status needed to unlock Pro; we never receive your payment details.

What we do not do

• No account or sign-in.
• No advertising and no advertising identifiers.
• No analytics, crash reporting or tracking SDKs.
• No servers: nothing you scan or write is uploaded to us.
• No sale or sharing of personal data.

Your choices

You can delete any document, empty the trash or remove all data by uninstalling the app or clearing its storage in Android settings. Data you exported or shared stays wherever you put it.

Children

Cadrivault is not directed to children and does not knowingly process children's personal data.

Changes

If this policy changes, the new version will be published on this page with a new date. Significant changes will also be described in the app's release notes.
