Privacy

We minimize data collection and keep core functionality on your device.

Local progress

Checklist state, spoiler preference, language preference, and journey selection are stored in browser localStorage. They are not received by our server. Clearing browser data removes them.

Import and export

Export creates a JSON file on your device. Import reads the file you select inside the browser; it is not uploaded to us.

Basic traffic analytics

After launch we may use privacy-friendly aggregate analytics such as Plausible to understand page traffic and basic referrals, without cross-site advertising profiles. If the analytics script is not enabled, this processing does not occur.

Contact

Privacy questions can be raised through the project GitHub issue tracker. Contact details will be updated at public launch.
