The short version
- Your documents stay on your device. We do not upload, view or store the files you scan, create or edit.
- We do not require an account, and we do not sell your personal information.
- We use Google Firebase for anonymous usage analytics and crash reports so we can fix bugs and improve the app.
1. Who we are
This Privacy Policy explains how the developer of PDF Master – Scanner & Tools (“the app”, “we”, “us”) handles information when you use the app. By using the app, you agree to the practices described here.
2. Your documents
Scanning, PDF creation, merging, splitting, compression, conversion, signing and other editing happen locally on your device. Images you capture and the files you open, create or edit:
- are stored only in the app's storage or in locations on your device you choose;
- are not uploaded to our servers, and we cannot access them;
- leave your device only when you share, export, print or save them to another app or cloud service yourself. In that case, the privacy policy of the service you choose applies.
If you uninstall the app, files stored in the app's private storage are deleted by your operating system. Files you saved elsewhere on your device stay there.
3. Information we collect
We do not ask for your name, email address, phone number or other contact details, and the app does not require an account. Through Firebase (see section 5), the following is collected automatically:
- Usage data: which features are used, screens viewed, session length, and app version.
- Device data: device model, operating system version, language, approximate country (derived from IP address), and app instance identifiers.
- Crash and diagnostic data: crash logs, stack traces, and the device state at the time of a crash.
This data does not include the content of your documents or scans.
4. Device permissions
| Permission | Why we ask |
|---|---|
| Camera | To scan documents. Images are processed on the device and are not sent to us. |
| Photos / Storage / Files | To import images and PDFs you select and to save the files you create. |
| Internet | To send anonymous analytics and crash reports. Document features work offline. |
You can grant or revoke these permissions at any time in your device settings. Some features may not work without them.
5. Third-party services
The app uses these services provided by Google LLC:
- Google Analytics for Firebase: helps us understand how the app is used.
- Firebase Crashlytics: helps us find and fix crashes.
Google processes this data under its own terms. Learn more at Firebase Privacy and Security and the Google Privacy Policy. The app does not show third-party advertising.
6. How we use information
- To keep the app working reliably and to diagnose and fix crashes and bugs.
- To understand which features are useful and improve the app.
- To meet legal obligations.
Where the GDPR or a similar law applies, we process analytics and crash data based on our legitimate interest in providing a stable, improving app, or on your consent where the law requires it.
7. Sharing
We do not sell or rent your information, and we do not share it for targeted advertising. We share data only with the service providers listed above, who process it on our behalf, or when the law requires it, for example in response to a valid legal request.
8. Data retention
Analytics data is kept for the retention period set in Google Analytics for Firebase, and crash reports for the period set by Firebase Crashlytics (90 days by default). After that, the data is deleted or aggregated so it no longer identifies a device. Your documents are kept only on your device for as long as you keep them.
9. Security
Because your documents are processed and stored locally, they are protected by your device's own security, such as your lock screen and device encryption. Data sent to Firebase is encrypted in transit. No method of transmission or storage is completely secure, but we take reasonable steps to protect the information we handle.
10. Your choices and rights
Depending on where you live (for example under the GDPR in the EU/UK or the CCPA/CPRA in California), you may have the right to access, correct, delete, or restrict the processing of your personal information, to object to processing, and to data portability. You can also:
- reset your device's advertising/app identifiers in your device settings;
- revoke app permissions in your device settings;
- uninstall the app to stop all further collection.
Because we do not collect your name or contact details, we may need you to provide your app instance ID (if available) so we can find related data. To make a request, contact us using the details below. You also have the right to complain to your local data protection authority.
11. Children's privacy
The app is not directed to children under 13 (or the minimum age in your country). We do not knowingly collect personal information from children. If you believe a child has given us personal information, please contact us and we will delete it.
12. Changes to this policy
We may update this Privacy Policy from time to time. Changes are posted on this page with a new “Last updated” date. For significant changes, we may also notify you in the app.
