What this calculator stores, and what it does not.
This site is run by VinTech AS. Questions: harald@vintech.no.
You can calculate handicaps without an account. Start-list data stays in your browser until you choose to save a race.
If you sign in with email or Google, we store your email (and name, if you give one) plus the races, clubs, and rowers you save. That data is in Firebase, visible only to you unless you publish a race link.
After you accept, we use Firebase Analytics and Vercel Analytics to see which pages are used. Decline (or clear this site's data in your browser) and we do not load those tools. The calculator still works.
