We try to keep data collection to what's needed to run the app and its ad-supported free features. We collect information in three ways:
PDF Reader does not require account creation or sign-in. We do not collect your name, email address, or phone number directly through the app.
| Permission | Why we ask for it |
|---|---|
| Storage / manage external storage | To find, open, and organize PDF files and wallpapers you choose to view or set. |
| Post notifications | To show reminder and update notifications, which you can disable anytime. |
| Internet / Advertising ID | Required to load ads, sync configuration, and send anonymous analytics. |
You can review or revoke any of these permissions at any time from your device's Settings > Apps > PDF Reader > Permissions. Some features (like opening PDFs) will not work correctly without the storage permission.
PDF Reader is a free, ad-supported app. Our advertising and analytics partners may collect your advertising identifier, general device information, and approximate location (derived from IP address) to serve ads, measure performance, and prevent fraud. Some partners may build an advertising profile across apps to personalize ads, subject to your device's ad settings and, where applicable, your consent choice shown in-app.
We use Firebase Analytics to understand how people use the app (screens visited, features used, crash frequency) in aggregate — this data is not used to identify you personally.
We do not sell your personal information. We share the limited data described above with:
Analytics and crash data are retained by our providers per their own retention policies (typically up to 14 months for Firebase Analytics, configurable on our end). Installation attribution records in our database are retained as long as needed for attribution reporting, after which they are periodically purged. PDF files and other content you open never leave your device through us.
We rely on Android's app sandboxing and Firebase's infrastructure security (encryption in transit) to protect data in our systems. No method of electronic storage or transmission is 100% secure, and we cannot guarantee absolute security.
PDF Reader is not directed at children under 13 (or the equivalent minimum age in your region), and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us using the details below and we will remove it.
We may update this policy from time to time to reflect changes in our practices or for legal reasons. We'll update the "Last updated" date above when we do. Continued use of the app after changes take effect means you accept the revised policy.
