PDF Chat – Privacy Policy
This policy explains what the PDF Chat Android app ("PDF Chat", "we") collects, why, who processes it, and the choices you have. It applies only to the PDF Chat Android app.
1. Summary
- PDF tools (merge, split, compress, convert, scan) run entirely on your device. Those files are not uploaded.
- AI features (chat, summaries, flashcards, quizzes, notes) send your document's text, and for chat the PDF file itself, to our server so an AI model can answer. See section 3.
- We use Google Firebase (sign-in, analytics, crash reports), Google AdMob (ads) and RevenueCat with Google Play Billing (subscriptions).
- We do not sell your personal data. We do not use your documents to show you ads.
2. Data stored on your device
Documents you open in AI features are copied into the app's private storage, together with the extracted text, your chat history, saved summaries and study progress. This data stays on your device, is excluded from Android backups, and is deleted when you uninstall the app or clear its data.
3. Documents and AI processing
When you use an AI feature:
- The PDF file is uploaded and its extracted text is sent to our backend at
ai-platform.neetpav46.workers.dev, hosted on Cloudflare Workers. - For each question or summary, the relevant passages of the document, your question and recent messages from the conversation are sent to an open-source AI model (such as Meta Llama, Qwen or Mistral) running on Cloudflare Workers AI, which generates the answer. Your content is not sent to any other AI company.
- Uploaded files and text are kept until you delete the document in the app (deleting a chat from your history also deletes its uploaded copy) or ask us to delete them. They are used only to provide the feature you asked for, and are not used to train AI models, by us or by Cloudflare.
Do not upload documents you are not allowed to share with a third-party service. AI answers can be wrong. Check important information against the original document. You can report any answer with the flag button under it.
4. Data we collect
| Data | Purpose | Processor |
|---|---|---|
| Anonymous account ID (Firebase anonymous sign-in) and an app-generated device ID | Authenticate requests to our AI server, track your AI credit balance, link purchases | Google Firebase, our Cloudflare backend |
| Document files, extracted text, questions and AI answers | Provide AI features (section 3) | Cloudflare |
| App usage events (e.g. feature used, success or failure, timing). These never include document or answer text. | Analytics and product improvement | Google Firebase Analytics |
| Crash logs and device information (model, OS version) | Fixing crashes | Firebase Crashlytics |
| Advertising ID, IP address, approximate location derived from IP, ad interactions | Showing ads to free users, measuring them, preventing fraud | Google AdMob |
| Purchase and subscription status (no card details; Google Play handles payment) | Unlock Premium, restore purchases | RevenueCat, Google Play |
| Answer ratings (category only) | Improve answer quality | Google Firebase Analytics |
| Reported answers: the answer text you report and the reason you pick | Review and remove harmful AI output | Our Cloudflare backend |
The camera is used only for the document scanner. Text recognition (OCR) runs on your device using Google ML Kit.
5. Ads and consent
Free users see ads from Google AdMob. In the EEA, the UK and Switzerland, we ask for your consent through Google's consent form before personalised ads are shown. You can change your choice at any time in Settings → Privacy options. Elsewhere you can reset or delete your advertising ID in Android settings. Premium users see no ads. See how Google uses data from apps that use its services.
6. Sharing
We share data only with the processors listed above, so they can run the app's features, and when the law requires it. We do not sell personal data.
7. Retention
- On-device data: until you delete it, clear app data or uninstall.
- Uploaded documents and text: until you delete the document in the app, or ask us to delete them.
- AI credit balance and anonymous account record: while you use the app, and until you ask us to delete them.
- Analytics and crash data: according to Firebase's retention settings (default 14 months for analytics).
8. Your choices and data deletion
You can delete local data at any time by clearing the app's data or uninstalling it. Deleting a chat from your history in the app also deletes that document from our server. To delete everything held on our servers (uploaded documents, credit balance, account record), email neetpav786@gmail.com from inside the app (Settings → Contact Developer). We will complete the request within 30 days. Depending on where you live, you may also have the right to access, correct or port your data, or to object to processing. Contact us at the same address.
9. Security
All traffic between the app and our server uses HTTPS. Access to our AI server requires a signed Firebase token.
10. Children
PDF Chat is not directed at children under 13 (or the minimum age required in your country), and we do not knowingly collect their personal data.
11. Changes
If this policy changes, we will update the date above. Significant changes will also be announced in the app.
