Privacy Policy - PDF Reader Pro

1. Information we process

Depending on how you use the app, we or our service providers may process the following categories of information:

Device and app information such as model, operating system, language, app version, and diagnostic events.
Identifiers used by advertising, analytics, installation, consent, or crash reporting SDKs.
Files and file metadata that you explicitly choose to open, merge, compress, convert, protect, share, or manage inside the app.
Support messages you send to us by email.
Purchase and entitlement status when you use optional paid features delivered through Google Play.

2. Why we process information

To open, display, organize, and transform PDF documents and related files you choose inside the app.
To keep the app stable, monitor crashes, measure performance, and understand feature usage.
To show ads, manage consent choices, and limit advertising for paid users where applicable.
To deliver remote configuration, app messaging, promotions, premium access, and support responses.
To comply with legal obligations, enforce our terms, and protect users, the app, and our systems.

3. Storage access and document handling

PDF Reader Pro works with files stored on your device. When you grant storage-related permissions or pick files through Android system dialogs, the app can access those files to perform the action you request.

Your documents may be copied, renamed, merged, compressed, locked, or exported locally on your device as part of the workflow. We do not describe those files as "uploaded to us" unless a future feature clearly says so.

4. Third-party services

The codebase for the current app release includes third-party services such as:

Google Play billing for optional purchases.
Google AdMob and Google User Messaging Platform for advertising and consent management.
Firebase services for analytics, remote configuration, installations, and crash reporting.

These providers act under their own privacy terms and may process technical information, identifiers, consent state, and event data.

5. Sharing

We do not sell your documents. We may share limited information with service providers that help us operate the app, including analytics, advertising, crash reporting, consent, hosting, and billing partners.

We may also disclose information when required by law, to respond to valid legal process, or to protect rights, safety, or the integrity of the service.

6. Retention

Local files remain on your device unless you delete them or use a tool that creates a replacement export. Technical records from analytics, crash reporting, ads, billing, and support may be retained for the period reasonably needed for operations, security, legal compliance, dispute handling, and financial reporting.

7. Security

We use reasonable administrative and technical measures to protect our services, but no transmission or storage method is completely secure. You remain responsible for protecting access to your device, backups, and any exported or shared documents.

8. Children

The app is not directed to children under 13, and we do not knowingly request that children provide personal information through the service.

9. International use

The app may be distributed globally through Google Play, and service providers may process information in countries other than your own. Those transfers occur subject to the provider's operational safeguards and applicable law.

10. Your choices

You can deny permissions, but some PDF workflows may stop working correctly.
You can manage advertising and consent preferences through supported prompts where available.
You can contact us to ask privacy questions about the current public release.

11. Changes to this policy

We may update this policy as the app, legal requirements, or third-party services change. The latest version will be posted on this page with a revised effective date.
