Privacy
Everything on this site runs in your browser. Scoring, Predict, Coach, and Batch CSV never send your numbers anywhere — there is no backend and no account, and nothing you type is uploaded.
What is saved on this device
So return visits don't start blank, the site keeps your calculator entries, Coach settings, and weekly progress log in your browser's local storage (one record, key twip:v1). It stays on this device and is never uploaded. You can wipe it at any time:
What is counted
We use PostHog in cookieless mode to count which pages are visited: PostHog itself stores nothing in your browser (no cookies, no analytics storage), no person profiles are built, and click/session recording is off. Unique visitors are estimated from a hash PostHog discards daily. Pageviews are sent through this site's own domain, so your browser never contacts a third-party host directly.
