Privacy Policy

Last updated: August 15, 2026

We designed this app with privacy in mind. Images selected for compression are processed locally on your device and are not uploaded to our servers. We do not display third-party advertisements, we do not use the Identifier for Advertisers (IDFA), and we do not track you across apps or websites owned by other companies.

1. Information We Process

Images. When you select images for compression or resizing, the images are processed locally on your device. We do not upload, store, or collect your images on our servers.

Usage analytics. We use Firebase Analytics and Umeng Analytics to understand how the app is used and to improve its features, stability, and user experience. These analytics services may process limited technical and usage information, such as app interactions and events, app version, device model, operating system version, language or region settings, network-related information, IP address, and device-level identifiers used for analytics, such as IDFV or analytics-generated identifiers.

We do not use IDFA for analytics, advertising, or any other purpose. Analytics information is not used by us to track you across apps or websites owned by other companies.

Purchases. In-app purchases are processed by Apple through the App Store and StoreKit. We do not receive or store your payment card or banking information. The app may receive purchase status or transaction information from Apple as necessary to provide purchased features.

2. How We Use Information

Analytics information is used only to understand app usage, measure feature performance, diagnose technical issues, improve reliability, and improve the overall user experience.

We do not use analytics information for third-party advertising, personalized advertising, cross-app tracking, cross-website tracking, or sale to data brokers.

3. Tracking and Advertising

The app does not contain third-party advertising. We do not use IDFA and do not use information collected from this app to track you across apps or websites owned by other companies for advertising or advertising measurement.

The app does not request permission through Apple's AppTrackingTransparency framework because the app does not engage in tracking as defined by Apple.

4. Third-Party Analytics Services

We use the following third-party analytics services:

These service providers may process analytics and technical information on our behalf in accordance with their own privacy and security practices. We use these services for analytics purposes only and not for advertising or cross-app or cross-website tracking.

5. Image Privacy

Your images remain on your device during compression and resizing. The app does not upload your images to our servers or to Firebase Analytics, Umeng Analytics, or any other analytics provider.

Analytics events are intended to describe how app features are used and do not include the content of your images.

6. Data Retention and Deletion

We do not operate a server that stores your images.

Analytics information may be retained by Firebase Analytics and Umeng Analytics for the period necessary to provide analytics services and according to their applicable retention practices.

You may contact us at any time with questions about our privacy practices or requests relating to data that we control. In some cases, analytics information may not be directly identifiable as belonging to a particular individual, which may limit our ability to locate or delete a specific analytics record.

7. Children's Privacy

The app is not designed to collect personal information from children. We do not knowingly collect children's images, names, contact information, or other user-created content on our servers.

8. Security

We use reasonable measures designed to protect information handled by the app. Processing images locally on the device reduces the amount of user content transmitted over the internet.

9. Apple's Services

Apple may independently process information when you download the app, use App Store services, or make an in-app purchase. Apple's processing of that information is governed by Apple's own privacy policies.

10. Changes to This Privacy Policy

We may update this Privacy Policy when the app's features, analytics practices, or legal requirements change. The updated version will be posted on this page with a revised “Last updated” date.
