Privacy policy
Secure PDF for Android · Last updated 28 August 2026
Secure PDF collects no personal data, has no analytics, no crash reporting, no advertising and no user accounts. Your documents are processed entirely on your device and are never uploaded to us or to anyone else.
The short version
There is no server behind this app. There is nothing for you to sign in to, no profile, and no record of what you open. Put the phone in airplane mode and every tool still works, which is the simplest way to check any of this for yourself.
What we collect
Nothing.
We do not collect your name, email address, phone number, location, contacts, device identifiers or advertising ID. We do not know how many documents you have opened, which tools you use, or whether the app worked. The app contains no analytics library and no crash reporting library of any kind.
Your documents
Every operation — compressing, merging, splitting, signing, redacting, text recognition, encryption — runs on your device using your device’s own processor. Files are never transmitted anywhere.
The app requests no storage permission. It can only read a file you have explicitly handed it through Android’s own file picker, or one shared to it from another app. It cannot browse your storage.
While a job runs, a working copy is written to the app’s private cache so the original is never modified in place. These copies are removed automatically, and you can clear them at any time from Settings.
Permissions, and why each one is there
| Notifications | So a long job can finish while you use another app. Optional; declining it does not disable anything. |
|---|---|
| Billing | Only for the optional tip. Payment is handled entirely by Google Play; the app never sees a card number. |
| Internet, network state | Requested by Google's own libraries for in-app purchases and for downloading the offline text-recognition model. The app itself never sends a document anywhere. |
| Wake lock, run at startup | Declared by Android's WorkManager, which is what lets a long job survive you switching apps. |
The app requests no advertising ID. You can verify the full permission list on the Google Play listing before installing, and compare it with any other PDF app.
Third-party components
Two Google libraries are built into the app. Neither receives your documents.
- Google Play Billing handles the optional tip. Google processes the payment and tells the app only whether a purchase completed.
- Google ML Kit performs text recognition and document edge detection. Recognition runs on your device and your pages are not uploaded. The recognition model itself is delivered by Google Play services, and ML Kit reports its own usage statistics to Google independently of this app, under Google’s privacy policy. We mention this because it is the one part of the app we do not control, and we would rather say so than let you assume otherwise.
What is stored on your device
Your settings, the order you arranged your tools in, a list of recently used file names, and a count of how many times you have left a tip. All of it lives in the app’s private storage on your phone, is never transmitted, and is deleted when you uninstall the app.
Children
Secure PDF is a document utility with no social features, no user-generated content and no data collection, so it is suitable for all ages. We do not knowingly collect information from anyone, of any age, because we do not collect information at all.
Your rights
Rights to access, correct, export or delete personal data are central to the GDPR and to India’s Digital Personal Data Protection Act. They do not apply here in any practical sense, because we hold no personal data about you to access, correct, export or delete. Uninstalling the app removes everything it stored.
Changes
If this policy changes, the date at the top changes with it. If a future version of the app ever collects anything, that will be stated here plainly and before the release, not quietly after it.
