Privacy Policy

Official Privacy Policy for Photo Compressor & Resizer (com.launchstack.exactkb) • Developed by LaunchStack

This Privacy Policy applies to the mobile application Photo Compressor & Resizer (package name: com.launchstack.exactkb), developed by LaunchStack (https://lstack.co). This policy describes our data handling practices and strict compliance with Google Play Developer Policies.

1. Zero Personal Data Collection

Photo Compressor & Resizer does not collect, store, share, sell, or transmit any personal data. We do not require accounts, logins, or user registration. We do not access or transmit your name, email, contact list, location coordinates, or device identifiers.

2. 100% Local On-Device Processing

Photos selected for compression or resizing are loaded strictly into temporary device memory and processed entirely on-device. No photos or image data are ever uploaded to any server, cloud service, or third party.

3. Android Permissions

READ_MEDIA_IMAGES / READ_EXTERNAL_STORAGE: Used solely to allow you to select photos from your device gallery. Photos are accessed locally only.
WRITE_EXTERNAL_STORAGE: Used on legacy Android versions solely to save the compressed image back to your photo library.
INTERNET: Used solely by the Google Mobile Ads (AdMob) SDK to request and display advertising banners.

The App explicitly blocks audio, video, camera, location, and contact permissions.

4. Advertising (Google AdMob)

Photo Compressor & Resizer displays advertisements provided by Google AdMob (Google LLC). AdMob may use standard device advertising identifiers (Android Advertising ID) in accordance with Google's Privacy Policy. You can reset or opt out of personalized ads at any time via Android Settings → Google → Ads. Our publisher record is hosted at https://lstack.co/app-ads.txt.

5. User Data Storage & Deletion

The App stores user preferences (theme, default ceiling) and an optional compression history log locally using device AsyncStorage. This data never leaves your device. You can clear it at any time via Settings → Clear History inside the App or by clearing app storage in Android settings. Because LaunchStack does not retain user data on any remote server, there is no remote user data to delete.

6. Children's Privacy

Photo Compressor & Resizer does not knowingly collect any information from children under 13 years of age. The App is a general utility with zero personal data collection.
