Privacy Policy

Last updated: March 18, 2026

        Short version: PDFCrush compresses your PDF files entirely on your device.
        Your files are never uploaded, shared, or seen by us. We show ads via Google AdMob,
        which may collect certain device information as described below.
    

1. Who We Are

PDFCrush is an Android application developed by an independent developer. This privacy policy explains how the app handles your data.

2. Data We Do NOT Collect

PDFCrush does not:

Upload, transmit, or store your PDF files anywhere
Collect your name, email, phone number, or any personal details
Require account registration or sign-in
Track your location
Share any data with the app developer

All PDF compression happens 100% locally on your device. Compressed files are saved to your device storage only.

3. Advertising (Google AdMob)

PDFCrush displays ads provided by Google AdMob. To serve relevant ads, AdMob may collect and use the following information from your device:

Advertising ID (resettable device identifier)
IP address (used to infer approximate location for ad targeting)
Device type, OS version, and language settings
Ad interaction data (impressions, clicks)

This data is collected and processed by Google, not by PDFCrush. Google's data practices are governed by the Google Privacy Policy.

You can opt out of personalised advertising at any time by going to your device Settings → Google → Ads → Delete advertising ID (Android 12+) or Opt out of Ads Personalisation (older Android).

4. Permissions Used

INTERNET — Required to load advertisements via Google AdMob. Not used to upload your files or any personal data.
READ/WRITE Storage (implicit via Storage Access Framework) — Required to let you select a PDF file and save the compressed result to your Downloads folder. Files are accessed only when you explicitly choose them.

5. Compression History

PDFCrush saves a local history of your compression sessions (file name, original size, compressed size, date) to display in the History screen. This data is stored only on your device using Android's SharedPreferences and is never transmitted anywhere. You can delete individual history entries or all history at any time within the app.

6. Children's Privacy

PDFCrush is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through the app, please contact us and we will take steps to remove it.

7. Changes to This Policy

We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated date. Continued use of the app after changes constitutes acceptance of the updated policy.
