2. Scope
This policy applies to the Lighten iOS app.
3. On-device information
Debt relationships, amounts, dates, payments, reserves, tasks, communication logs and settings are stored on your device. No account is required and these records are not uploaded to our servers.
4. System and network services
Screenshot recognition uses Apple Vision on the device. App lock uses system authentication and reminders use local notifications. The app makes no advertising requests and sends no events to remote analytics services.
5. Permissions and choices
The app uses system features when you select a screenshot or enable notifications. You can manage notification and authentication permissions in system settings; related features may be unavailable when disabled.
6. Backup and restore
Backups are initiated by you and encrypted with a password you set, then saved to your chosen location. Protect your password and backup. Restore replaces local data after confirmation. Manage external copies separately.
7. Retention and deletion
Local content is managed through the app's save and delete features. Uninstalling usually removes its storage; manage system backups, exports and copies on other devices separately. Save required content before uninstalling.
8. Information about others
When recording information about others, ensure you have authority to process it, keep only what is needed, and protect your device and backups.
9. Contact and updates
For privacy and product support, contact contact@tricosmos.cn. Your email address, questions and attachments are used to handle your request. Do not send passwords or unrelated private information. Changes to data processing will be described here.
