Privacy Policy

Last updated: November 2, 2026 • Effective date: September 15, 2026

Your privacy is our utmost priority. Photo Compressor & Resizer was engineered from the ground up as a standalone, privacy-first utility. We firmly believe your personal photos belong to you alone. This policy details our strict zero-data collection architecture, permissions utilized, and third-party advertising disclosures in strict accordance with the Google Play Developer Distribution Agreement and User Data policies.

1. Google Play Data Safety Declarations

Data Category	Collected or Shared?	Processing Details
Photos & Videos	No (0 bytes collected)	Processed 100% locally on your phone hardware. Never transmitted.
Personal Information	No	No account, registration, name, email, or identity required.
Location Coordinates	No	Optional EXIF stripping removes GPS metadata prior to saving.
Device / Ad IDs	Third-Party Only (AdMob)	Google AdMob may process Android Advertising ID for banner ads.
Analytics & Crash Telemetry	No	Zero custom telemetry or server tracking.

2. 100% On-Device Processing Architecture

When you select an image in Photo Compressor & Resizer, the image file is loaded strictly into your Android device's local volatile memory (RAM). Our binary-search image compression engine executes entirely within your device's native runtime environment. At no point in time is your image content, thumbnail, or metadata ever uploaded to any cloud server, API, remote service, or external network. The application works with complete functionality even in airplane mode with all network connections turned off.

3. Device Permissions & Purpose

Photo Compressor & Resizer requests only the minimum Android operating system permissions strictly required for photo compression:

• READ_MEDIA_IMAGES / READ_EXTERNAL_STORAGE: Required to allow you to browse and select photos from your device gallery using Android's system photo picker. Images are read strictly in-memory on your device and are never transmitted.
• WRITE_EXTERNAL_STORAGE: Required on legacy Android versions (Android 9 and below) to save the resulting compressed image back into your device's photo gallery.
• INTERNET & ACCESS_NETWORK_STATE: Utilized exclusively by the Google Mobile Ads (AdMob) SDK to request and render banner advertisements.

Photo Compressor & Resizer does not request microphone, camera, contacts, location, audio, or video permissions.

4. Advertising & Google AdMob

To keep Photo Compressor & Resizer free for all users, we display non-intrusive banner advertisements provided by Google AdMob (Google LLC).

Google AdMob may automatically collect and process certain standard telemetry to serve advertisements, including:

• Google Advertising ID (AAID)
• Approximate device model, language, and network connection characteristics
• Ad impressions, interactions, and viewability diagnostics

AdMob data usage is subject to the Google Privacy Policy and Google AdMob Policies. You can opt out of personalized advertising at any time through your Android device settings: Settings → Google → Ads → Reset or Delete Advertising ID.

LaunchStack maintains an authorized publisher record at https://lstack.co/app-ads.txt.

5. Local Data Storage & History

The App stores local configuration settings and an optional recent compression history log exclusively on your device using AsyncStorage:

• Preferred UI theme (Light/Dark/System default)
• Your last selected target size preset (e.g. 200 KB)
• EXIF metadata stripping toggle preference
• Local history log (timestamp, original size, compressed size)

This data is stored purely within the application's private sandbox and is never uploaded externally. You can clear your entire history at any time by tapping Clear History in the Settings screen, or by clearing app storage in Android settings.

6. EXIF Metadata Removal

Digital photos often contain EXIF data such as GPS coordinates, camera make/model, aperture, and capture timestamps. When "Strip EXIF Metadata" is enabled (default), Photo Compressor & Resizer strips these tags during compression before writing the final output image. This operation occurs strictly on your device to protect your privacy when sharing images online.

7. Children's Privacy (COPPA & Families Policy)

Photo Compressor & Resizer does not knowingly collect, request, or solicit any personal information from children under the age of 13. The application is a general utility tool with no user accounts, no social components, and no data collection mechanisms.

8. Third-Party Libraries & SDKs

The only third-party SDK integrated into Photo Compressor & Resizer is:

• Google AdMob (Google Mobile Ads SDK): Used for advertisement delivery. Privacy policy: https://policies.google.com/privacy

We do not incorporate third-party analytics trackers (such as Google Analytics, Mixpanel, or AppsFlyer) or social login SDKs.

9. Changes to This Privacy Policy

We may update our Privacy Policy periodically to reflect app updates or regulatory requirements. Any modifications will be posted to this URL with an updated date. Continued use of the application following the posting of modifications constitutes acceptance of the revised terms.

10. Your Rights & Data Deletion (Google Play Compliance)

Because LaunchStack does not collect, transmit, or store your photos or personal data on any server, there is no remote user data held by us to access, rectify, or delete.

How to Delete Data: All app configuration preferences and local history logs are stored purely on your local device. You can immediately delete all local data at any time by:

• Tapping Settings → Clear History inside the Photo Compressor & Resizer app, or
• Clearing the app's cache and data via Android Settings → Apps → Photo Compressor & Resizer → Storage → Clear Data, or
• Uninstalling the application from your device.
