Operator
Lighten is provided by Hangzhou Jianlan Zhiwei Technology Co., Ltd. Updated September 30, 2026.
Media processing
Your selected photos and videos are processed on your device. Lighten does not upload them or scan your entire photo library. Originals remain unchanged. Output retains supported location and capture information; a change such as removing transparency requires your confirmation.
Local storage and deletion
Working files, results, rules and settings are stored on your device. Unsaved results remain until you delete them. Results saved to Photos or Files may be cleared after 24 hours; externally saved files are unaffected. You can delete tasks and results in History and clear saved results in Storage.
System and purchase services
The system may retrieve originals from iCloud or your file provider. Apple handles purchases and restore requests. Optional completion notifications are local. Lighten requires no account and includes no advertising or third-party analytics SDK. System backup and diagnostics remain subject to your device and Apple settings.
Support and privacy requests
If you contact support, we receive the message and attachments you choose to send. Optional diagnostics contain only the app version, device type, iOS version and a non-sensitive error code. We use this information to resolve your request. Contact us to request access, correction or deletion of your support correspondence, subject to applicable retention duties.
