Privacy Policy

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.

This version of the app uses Google Analytics only for basic usage measurement, such as page views and general device or browser information, so the developer can understand how the app is being used.

• No in-app account creation.
• No payment processing.
• No advertising network integration in the app code.
• No analytics data is sold to third parties.
• Analytics data is not used by this app for advertising or ad targeting.
• Collection progress, mastery state, backups, and imported data are not sent to Google Analytics by the app logic.

Google Analytics may receive technical information such as IP address, browser or device characteristics, approximate geography, and page interaction events in accordance with Google's own policies.

• Analytics helps measure traffic and feature usage across the app pages.
• The app does not intentionally attach your collection checklist data to analytics events.
• You can limit some analytics collection through browser settings, content blockers, or privacy tools.

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.

If you need help with the app or want to request changes to this policy, use the support information on the support page.
