Privacy Policy
DocMaster is a document and file toolkit for Android. Your documents stay on your device — but the app is free and supported by ads, and it uses analytics to run and improve, so it does collect some usage data and identifiers through Google's services, described below.
What stays on your device (never uploaded)
Your files, folders, scanned documents, photos and recognised (OCR) text, and the on-device catalogue of file names and metadata that powers browse and search, are processed only on your device. DocMaster has no servers and does not upload, transmit or share the contents of your documents. Text recognition (OCR), document scanning and translation all run on the device (on-device translation downloads a language pack once from Google — the pack, not your text).
What is collected, and by whom
- Google AdMob (ads). To show ads, AdMob collects device and usage information, including an advertising identifier, device and app information, approximate (IP-based) location and ad-interaction data. This data is shared with Google and, for ad delivery and measurement, ad partners. See Google's policy.
- Google Analytics for Firebase (analytics). To understand usage and improve the app, we log app-activity events (for example screens viewed and which tools are opened) together with app instance identifiers and general device information. This is processed by Google on our behalf. See Firebase privacy.
- Firebase Remote Config. Used to fetch app configuration (such as which ad units to show). It does not collect your personal data or your files.
- Google Play Billing (Remove ads). If you buy Remove ads, Google Play handles the payment. The app receives only a confirmation that the purchase belongs to your Play account — never your payment details — and records the purchase in analytics.
We do not collect your name, email, contacts, precise location or the contents of your documents. There are no user accounts.
In Google Play's Data safety terms, DocMaster collects and shares App activity and Device or other IDs (including the advertising ID) with Google for advertising and analytics. It does not collect or share your files, photos or documents. Data is sent over encrypted (HTTPS) connections.
Consent (EEA / UK)
Where required (for example in the EEA and UK), the app shows Google's consent message on first launch so you can choose whether to allow personalised ads. You can change this choice later from the app's ad consent options.
Permissions
- All files access (MANAGE_EXTERNAL_STORAGE) — asked for only when you choose to turn it on (for example from the Files tab), so the app can work as a file manager across your storage. Decline and it uses the system folder picker instead.
- Camera — only when you use the document scanner or ID-card scan.
Your choices and controls
- Reset or limit the advertising ID: Android Settings → Privacy → Ads.
- Ad consent: change your choice in the app's ad options (EEA/UK).
- Delete local app data: Android Settings → Apps → DocMaster → Storage → Clear data (removes the local catalogue, recents and favourites). Uninstalling removes all local data.
- Analytics and ads data held by Google: manage it through your Google account and the Google policies linked above, or contact us to request deletion of data associated with your device.
Children
DocMaster is a general-purpose utility, is not directed at children, and does not knowingly collect personal information from children.
