What the App Stores
Local device data only
The app stores your collection progress, variant mastery state, and saved timestamps locally in your browser storage so your checklist persists between visits and while offline.
- Collection and mastery state are saved in local browser storage.
- IndexedDB may also be used as a local backup on supported browsers.
- No sign-in, cloud sync, or developer-operated account system is required.
What the App Does Not Do
No ads or analytics SDKs
This version of the app does not intentionally collect personal information for advertising, profiling, or analytics through a dedicated third-party SDK.
- No in-app account creation.
- No payment processing.
- No advertising network integration in the app code.
User-Initiated Actions
Export, import, and sharing
If you choose to export your collection, import a backup, or share generated images or text, that action happens at your request using browser or device capabilities.
- Exports create a JSON file for you to store wherever you choose.
- Imports only read the file you explicitly select.
- Sharing uses your device share sheet or a downloaded file generated on your device.
