Practice without
handing over a trace.

No account, credentials, uploads or free-text fields are needed. Fictional examples ship with the page. No model executes.

In this browser

Local storage keeps only the IDs of missions you explored. It is not sent to us. Use Reset local progress to clear those marks. If storage is blocked, practice still works, but marks may not survive navigation.

Optional measurement

No analytics requests are sent before you explicitly opt in. Declining does not affect the missions. Analytics is restricted to the production hostname; local and Pages previews remain unmeasured.

After opt-in, a dedicated Google Analytics tag may receive fixed events: mission_started, mission_completed, hint_used, three_missions_completed and transfer_completed, practice_started and qualified_transfer_completed. Payloads contain a fixed mission ID, content version and, for transfer, two qualification booleans. No selected answers, fictional trace text, user text, URL query strings or referrers are intentionally sent. Automatic page views, enhanced measurement and advertising signals must remain disabled.

Google Analytics uses a browser identifier and receives network information such as an IP address when a request reaches it. Aggregate reports do not make the underlying service anonymous. No user account ID is supplied by this app. See Google’s privacy policy.

Consent and withdrawal

Consent and deduplication state are stored in session storage for the current tab session; browser session restoration can retain them. Withdrawal disables collection, removes accessible Google Analytics cookies and reloads the page with analytics off. Clearing local mission progress does not change consent or delete events already received by Google. No analytics events are queued before consent or replayed afterward.

Hosting and links

When published, the hosting provider may process normal request metadata to serve the site. External source links use their own privacy policies. There is no feedback form, email collection, payment or real tool execution here.
