Last updated: 8 November 2026
Pdfvio ("the app") is a PDF reader and PDF tools app for Android, published by Tech Dunya (PVT) LTD. ("we", "us"). This policy explains what information the app handles, what it does not collect, and your choices. We wrote it to be read, not skimmed – it is short because the app collects very little.
1. The short version
- Your PDFs, scans, images and signatures are processed entirely on your device. They are never uploaded to us or to any server.
- The app has no account, no sign-up and no login.
- We do not collect your name, email, contacts, location or the contents of your documents.
- The app shows ads through Google AdMob, which may use your device's advertising ID. You can limit this in your phone settings and, where required, through the in-app consent form.
2. Information the app processes on your device only
To do its job, the app works with files you choose, such as PDFs you open, photos you convert, documents you scan with the camera, and signatures you draw. All of this stays on your phone:
- Files you open are copied temporarily into the app's private storage so they can be read, and are deleted automatically.
- Files the app creates (merged, compressed, converted, signed PDFs, and so on) are saved in the app's private storage and, if you keep the "Save copy to Downloads" setting on, in your phone's Downloads/Pdfvio folder.
- A signature you draw is stored as an image in the app's private storage so you can reuse it. You can delete it at any time in Settings → Delete saved signature.
- Your preferences (theme, settings) are stored on the device.
None of this information leaves your device, and we have no way to access it. Uninstalling the app deletes the app's private storage; files you saved to Downloads remain until you delete them.
3. Permissions the app uses
| Permission / feature | Why it is needed |
|---|---|
| Camera (through Google's document scanner) | Only when you tap Scan, to photograph documents. The scanner runs on your device via Google Play services. Photos are not sent to us. |
| Files and photos (through the Android file picker) | Only for the files and photos you select. The app cannot browse your storage on its own. |
| Internet | Used to load ads and, only when you use Web to PDF, to load the web page you type in. Your PDFs are never transmitted. |
| Sends a PDF you choose to Android's print service and the printer you pick. |
4. Advertising (Google AdMob)
Pdfvio is free and supported by ads served by Google AdMob, a service of Google LLC. To show and measure ads, the AdMob SDK may collect:
- your device's advertising ID (a resettable identifier),
- approximate location derived from your IP address,
- device and app information (device model, OS version, app version, language, screen size), and
- ad interaction data (which ads were shown, viewed or tapped).
We do not receive personal information from AdMob; we only see aggregated statistics. How Google uses this data is described in Google's Privacy Policy and How Google uses information from sites or apps that use its services.
Your choices:
- On Android, go to Settings → Google → Ads (or Settings → Privacy → Ads) to delete or reset your advertising ID or opt out of ads personalization.
- If you are in the European Economic Area, the United Kingdom or Switzerland, the app shows a consent form the first time it runs. You can change your choice at any time in Settings → Ad privacy options inside the app.
5. Google Play services and the document scanner
The Scan feature uses Google's ML Kit Document Scanner, which runs through Google Play services on your device. Scanned pages are processed locally and handed back to the app; we do not receive them. Google Play services is governed by Google's Privacy Policy.
6. Information we do not collect
We do not collect, store or share: the contents of your documents, your name, email address, phone number, contacts, precise location, photos (other than the ones you convert, which stay on the device), or any analytics about how you use the app. The app contains no crash-reporting or analytics SDK other than what AdMob needs to serve ads.
7. Data sharing and selling
We do not sell personal information. We do not share any data with third parties, except that the AdMob SDK communicates directly with Google as described in section 4.
8. Data retention
Because we do not collect your data, there is nothing for us to retain or delete. Files and settings on your device remain until you delete them or uninstall the app. Advertising data held by Google is subject to Google's retention policies.
9. Security
Your files are processed in the app's private storage, which other apps cannot read. PDFs you protect with a password are encrypted with 128-bit AES on your device. Keep in mind that no method of storage is completely secure, and that files you share or save to Downloads are outside the app's control.
10. Children
Pdfvio is not directed at children under 13 (or the age of digital consent in your country), and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us and we will delete it.
11. Your rights
Depending on where you live (for example under the GDPR or the California Consumer Privacy Act), you may have rights to access, correct, delete or restrict the use of your personal data, and to object to processing. Since we hold no personal data about you, these rights are mainly exercised through your device's ad settings and the in-app consent form described in section 4. For anything else, contact us at the address below.
12. Changes to this policy
If the app's data practices change – for example, if a future version adds a cloud feature – we will update this page and change the date at the top before the change takes effect. Continued use of the app after an update means you accept the revised policy.
