Privacy policy
Your images belong on your device.
Effective September 28, 2026
Rectangular Mosaic processes images locally in both the browser tool and mobile app. We do not upload images you select or edit to our servers.
1. Browser tool
The web tool uses browser File and Canvas APIs to read and process images you deliberately choose. Image data remains in the current page; when you close or refresh it, unexported results are not retained by this site.
2. Images and device permissions
The mobile app requests photo, camera, or storage permissions only when you choose a related action. You can withdraw these permissions in system settings.
3. Advertising and analytics
The free mobile app uses Google AdMob and may use Firebase Analytics and Microsoft Clarity for basic usage and stability information. These services do not receive images you edit.
4. In-app purchases
The mobile app uses RevenueCat to validate purchases, restore purchases, and manage Pro access. Payments are handled by the Apple App Store or Google Play.
5. Contact and updates
We may update this policy and will show a new effective date here. For privacy questions or data requests, email support@skstudio.cn.
