Privacy Policy

PDF & EPUB Reader (com.nakou.pdfreader)
Last updated: 10 September 2026

This policy explains what PDF & EPUB Reader ("the app") does with your information. The short version: the app does not have accounts, does not upload your documents, and the only data leaving your device is what Google's advertising service collects to show ads.

Your documents stay on your device

The app opens PDF and EPUB files you choose. Those files are read directly from the location you picked, on your device. The app never uploads, transmits, copies to a server, or shares the contents of any document you open. Document contents are not readable by the developer.

What the app stores on your device

To make the app usable, the following is saved in the app's own private storage:

• A list of recently opened files: the file name and the system reference to it.
• The last page you read in each document, and any bookmarks you added.
• Your display preferences, such as night mode and scroll mode.
• Small preview images of recently opened documents, and the unpacked contents of EPUB files, kept in the app's temporary cache.

All of this stays on your device. None of it is transmitted anywhere. Uninstalling the app deletes it. Clearing the app's storage from Android Settings also deletes it. The app has Android backup disabled, so this information is not copied to your cloud backups.

Advertising

The app is free and supported by ads served through Google AdMob. To provide and measure those ads, Google collects information such as:

• Your device's advertising identifier
• Device and app information, such as model, operating system version and app version
• Approximate location, derived from your IP address
• Ad interaction data, such as which ads were shown and whether they were tapped

This collection is performed by Google, not by the developer, and is governed by Google's own policies. See How Google uses information from sites or apps that use our services and the Google Privacy Policy.

What the app does not do

• No user accounts, sign-in, or registration.
• No collection of your name, email address, phone number or contacts.
• No precise or GPS location access.
• No access to your camera, microphone, contacts, or messages.
• No selling of personal information.
• No analytics beyond what Google AdMob performs for advertising.

Your choices

• Limit ad personalisation. On Android, open Settings, then Privacy, then Ads, where you can delete or reset your advertising ID and opt out of personalised ads.
• Remove locally stored data. Clear the app's storage in Android Settings, or uninstall the app.

Children

The app is a general-purpose document reader. It is not directed to children under 13, and the developer does not knowingly collect personal information from children.

Data security

Information stored by the app is held in private app storage that other apps cannot read. Advertising requests made by the Google Mobile Ads SDK are sent over encrypted connections.
