Photo Shrink ("we", "the app") respects your privacy. This policy explains what data the app processes, why, and where it goes. All photo compression happens entirely on your device — your photos are never uploaded anywhere.
1. Data We Collect and Process
1.1 Advertising identifiers (Google AdMob)
The app shows ads via Google AdMob. To serve and measure ads, Google may collect the advertising ID and device identifiers, and use them for ad personalization, attribution, and fraud prevention, subject to your consent choices (EU/UK users are asked via a UMP consent dialog on first launch).
You can reset or limit your advertising ID in Android Settings (Ads / Privacy).
1.2 Analytics (Firebase Analytics)
We use Firebase Analytics to understand feature usage (e.g., counts of compressions and size savings percentages, ad impressions). Events contain no photos and no file names — only event types (such as task_start, task_success) and technical parameters.
No personal identity information (name, email, contacts, location) is collected.
1.3 Crash reporting (Firebase Crashlytics)
We use Firebase Crashlytics to collect crash logs and device state at the time of a crash, to keep the app stable. Crash reports do not include your photos.
1.4 Remote configuration (Firebase Remote Config)
Ad frequency parameters (e.g., interstitial caps) are remotely configurable via Firebase Remote Config. It does not collect user data.
2. Data We Do NOT Collect
No account, no sign-up, no personal information (name, email, phone)
No location data
No contacts, call logs, SMS, microphone, or camera access
Your photos are processed only locally: originals are read via the Android system Photo Picker, compressed copies are saved to your gallery via the system MediaStore, and compression history stays in on-device storage — nothing is ever transmitted to us or any third party
No cookies or tracking pixels
3. Permissions
Permission
Purpose
Notes
None. The app declares no camera, storage, or media permissions. Photo selection uses the Android system Photo Picker and saving uses the system MediaStore, neither of which requires a runtime permission.
4. Data Retention and Deletion
Local data (compression history, settings) stays on your device until you delete it: use Settings → Clear History, or uninstall the app to remove everything. Compressed photos you saved to the gallery are yours and remain until you delete them.
Analytics/advertising data collected by Google is governed by Google's retention policies.
The app is a general-audience utility rated for adults (18+ target audience declaration). We do not knowingly collect data from children under 13.
7. Changes to This Policy
We may update this policy as features change (e.g., when ad mediation is added). Material changes will be reflected by an updated effective date and in-app notice where appropriate.
