Short version: we don't know who you are, and we'd like to keep it that way.

We use two privacy-friendly tools to understand whether the site works and whether anyone visits it:
Umami — self-hosted, anonymous, aggregated page views, approximate country, browser type, and the page that referred you. No cookies, no IP addresses retained, no fingerprinting. Runs on our own server in the EU (stats.plocic.dev).
Core Web Vitals — anonymous performance metrics (load time, layout stability) so we can spot slow pages, sent to our own EU server (vitals.plocic.dev). Same deal: no cookies, no identifiers.
Crash reports — if the app hits an error, you can send a technical report (error message, stack trace, the page) to our own EU server (report.plocic.dev) from the error screen, so we can fix it. Nothing is sent unless you tap it — never automatically. No personal data, no account info; there are no accounts.
None. The only thing we leave in your browser is the local cache your browser would keep for any website (and the in-memory query cache that disappears when you close the tab). No tracking cookies, no consent banner needed.
Tournament information is fetched from the public sumo-api.com service. We do not forward any information about you to it; we only request the public data you see on the page.
Because we don't collect personal data, there's nothing tied to you to access, correct, export, or delete. You are welcome to use the site without identifying yourself in any way.
If laws like the GDPR or CCPA apply to you and you have questions, the contact below works for those too.

If this policy changes, the “last updated” date at the top will move with it. Material changes will be called out on the homepage.
