PDF Tools ("the App") is a PDF utility application. We are committed to protecting your privacy. This policy explains what data we collect (very little) and how we handle it.
All PDF processing — merging, splitting, compressing, signing, watermarking, and all other operations — happens entirely on your device. No files are uploaded to any server. Your documents never leave your phone.
### Analytics (minimal) We collect anonymous usage data to improve the app:
This data is collected via Firebase Analytics and Firebase Crashlytics. It contains no personally identifiable information — no names, emails, file contents, or file names.
### In-App Purchases Subscription purchases are processed entirely by Google Play or Apple App Store. We do not collect, store, or have access to your payment information. Purchase validation is handled by RevenueCat, which receives only your anonymous app user ID.
### Advertising The free version displays banner ads via Google AdMob. AdMob may collect device identifiers for ad personalization. You can opt out of personalized ads in your device settings. Pro subscribers see no ads.
We do not sell, trade, or share your data with third parties, except:
No user data is stored on our servers. Analytics data is stored by Firebase under Google's privacy policies. Temporary files created during PDF processing are stored locally and cleaned up automatically.
The App does not knowingly collect data from children under 13. The App contains no age-restricted content.
Since we collect minimal anonymous data, there is little personal data to manage. If you have concerns, contact us and we will address them promptly.
We may update this policy. Changes will be posted here with an updated date.

This app is ad-supported and uses Google AdMob to display ads. To serve ads, AdMob collects and processes your device's Advertising ID (a resettable identifier) together with related technical data (such as IP address, device information and ad-interaction data). This is used to deliver, measure and — where applicable — personalize advertising, and the data is shared with Google for this purpose. This processing is performed by Google under its own privacy policy: policies.google.com/privacy (see also how Google uses information from apps that use its services). Apart from the Advertising ID used for ads, the app collects no name, email, account, precise location or file content. Data is encrypted in transit.
You can reset or limit this at any time on your device: Settings → Google → Ads — “Delete advertising ID” or “Opt out of Ads Personalization”. To request deletion of data associated with your Advertising ID, email admin@99ersstudio.com and reset your Advertising ID in device settings.
