Privacy Policy

Effective Date: 11-July-2026

Document Scanner Vault ("we", "our", or "us") respects your privacy. This Privacy Policy explains how our app handles user data.

1. Overview

Document Scanner Vault is designed to help users scan, organize, encrypt, and securely store documents on their device.

The documents you create in the app — including scanned pages, images, generated PDF files, recognized (OCR) text, titles, folders/tags, and thumbnails — are stored locally on your device and are encrypted at rest. We do not upload your document content to our servers, and we cannot read your documents.

To improve the app and support optional features, we use Firebase services and a third-party advertising service provided by Google and other partners, and we offer optional, end-to-end encrypted cloud backup.

2. Information You Create in the App

The app may allow you to create and store document-related information, including but not limited to:

This information is stored locally on your device in encrypted form and is used only to provide the core scanning, editing, organizing, searching, saving, previewing, and exporting features of the app. Your documents are protected by your device's screen lock (fingerprint/face or PIN/pattern) and, where applicable, a recovery passphrase you choose.

We do not sell, share, or transmit your document content to our servers or to third parties, except as part of the optional cloud backup described in Section 6, where your data is encrypted on your device before it is uploaded.

3. Automatically Collected App Data

We use the following Firebase services:

These services may automatically collect certain app, device, usage, and diagnostic information, such as:

This data helps us understand how users interact with the app, detect crashes, fix bugs, improve performance, and improve the overall user experience.

We do not intentionally include document content, scanned images, recognized text, titles, or any other user-created document information in Firebase Analytics events or Crashlytics logs.

4. Advertising

The app may display advertisements provided by third-party advertising networks (for example, AppLovin and/or Google AdMob). To serve and measure ads, these partners may collect and process certain information, such as:

Advertising partners process this data according to their own privacy policies. We do not share your document content or scanned files with advertising networks. Where required, the app will request your consent for personalized advertising, and you can reset or limit your Advertising ID in your device settings.

5. Subscriptions

The app offers an optional paid subscription ("Secure Cloud") that unlocks encrypted cloud backup and sync. Subscriptions are purchased and managed through Google Play Billing. We do not receive or store your payment card details; payments are processed by Google Play according to Google's terms and privacy practices. We may receive your subscription status to enable the corresponding features.

6. Cloud Backup and Sync (Optional)

Cloud backup is optional and is off by default. If you choose to enable it:

If you disable cloud backup, the app removes your backup from the cloud.

7. Permissions

The app uses Android system-provided file, share, and document flows when you export or share a document; in those cases you choose the file, location, or sharing destination. We do not use device permissions for tracking, and we do not access files outside the app for advertising.

8. How We Use Data

We use locally stored, encrypted document data to provide the main functionality of the app, including scanning, editing, organizing, searching, saving, previewing, exporting, and reminders.

We use Firebase Analytics and Firebase Crashlytics data for:

We use advertising and subscription data to display and measure ads and to provide paid features. We do not use your document content for advertising, profiling, or selling to third parties.

9. Data Sharing

We do not sell user data.

We may share limited app usage, device, and crash diagnostic data with Google Firebase, and limited device and advertising data with our advertising partners, because these services are used in the app. These providers process that data according to their own privacy and security practices.

We do not share your document content, scanned images, generated PDF files, or recognized text with Firebase, advertising networks, or any other third party. Optional cloud backup uploads only end-to-end encrypted data that these providers cannot read.

10. Third-Party Services

The app uses the following third-party services:

These services may collect app, device, usage, diagnostic, and advertising information as described in this Privacy Policy.

11. Data Storage and Retention

Document data created inside the app is stored locally on your device in encrypted form. You can delete this data by deleting documents in the app (including emptying the Trash), clearing app data, or uninstalling the app.

If you enable cloud backup, encrypted backup data is retained until you disable backup or delete the corresponding documents. Firebase, advertising, and analytics data may be retained by the respective providers according to their data retention practices and our project settings.

If you contact us with a data-related request, we will make reasonable efforts to respond and assist where possible.

12. Children's Privacy

This app does not knowingly collect personal information from children. The app is intended for general document scanning and storage use. If we become aware that personal information from a child has been collected in a way that violates applicable requirements, we will take appropriate steps to delete or address that information.

13. Security

Documents created in the app are stored locally on your device in encrypted form and are protected by your device's screen lock. Optional cloud backup is end-to-end encrypted: your data is encrypted on your device before upload and can only be restored with your recovery passphrase. We recommend keeping your device secure by using a screen lock and keeping your operating system updated. Data transmitted by Firebase and advertising services is encrypted in transit according to their security practices.

14. Account Creation and Account Deletion

The app does not require you to create an account to use its core features.

An optional Google sign-in is used only to enable cloud backup. You can turn off cloud backup at any time from the app's settings, which removes your cloud backup, and you can revoke the app's access to your Google account from your Google Account settings. Locally stored app data can be deleted by deleting documents, clearing app data, or uninstalling the app.

You can also permanently delete your account from within the app, at any

time, from Settings → About → Delete account. This immediately and

permanently erases your encrypted cloud backup, your subscription

entitlement record, and your account itself from our systems. This action

cannot be undone.


Deleting your account does not delete the documents stored on your device,

which remain in your vault until you remove them yourself, and it does not

cancel any active subscription. Subscriptions are managed by Google Play and

must be cancelled there.


If your Secure Cloud subscription ends and is not renewed, your encrypted

cloud backup is retained for 6 months and is then permanently deleted

automatically, along with the associated subscription records. Resubscribing

at any point during those 6 months preserves your backup in full. Documents

stored on your device are never affected by this and are not deleted.


Your documents are encrypted on your device before they are uploaded, using

a key that only your recovery passphrase can unlock. That passphrase is never

transmitted to us and we do not store it. As a result, we are unable to read

the contents of your cloud backup, and we are equally unable to recover it on

your behalf if your recovery passphrase is lost. There is no reset mechanism

and no support process that can restore access. If you do not have your

recovery passphrase, your cloud backup is permanently unreadable.


If you do not use cloud backup, no documents or document data are transmitted

to or stored on our servers at any time.

15. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated effective date.
