What we collect, and what we do not

Who runs this site

Sauna.Guide is operated by AC0 AI S.L.U. (NIF B26808741), the data controller for anything described here. Full registered details are on the Aviso Legal page. Questions, or to exercise any of your rights below, email david@sauna.guide.

How we measure the site

We use one first-party analytics cookie to count page visits and recognise a returning visitor anonymously, so we can see which guides are useful and whether the site works. It stays on your device, on our own domain. We never share it with ad networks and never use it to track you across other websites.

Cookies we use

One first-party analytics cookie, set by PostHog through our own domain. You can block or delete it any time in your browser settings, and the site keeps working without it. We may also use strictly necessary browser storage for basic platform behavior. We do not use advertising cookies.

Tools we use

• PostHog for product analytics, hosted in the EU. Traffic is routed through our own domain (a reverse proxy at /ingest), and it sets one first-party analytics cookie. We do not share it with third parties.
• Vercel Analytics and Speed Insights for aggregate page metrics and performance. These are cookieless and do not identify you.
• Google Search Console shows us how pages perform in Google Search. Google processes that search data on Google's side.

We do not sell your data, we do not run ad networks, and we do not track you across other websites.

Your rights

Under the GDPR you can ask us to access, correct, or delete your data, or object to its processing. Email david@sauna.guide and we will handle it. Our analytics are anonymous and not linked to your name or email, so in practice there is little personal data to delete, and you can clear the analytics cookie yourself in your browser at any time. You also have the right to complain to the Spanish data protection authority (AEPD).

Retention and changes

We keep analytics only as long as it is useful for improving the site. If this policy changes in a way that matters, we will update the date at the top and, where required, ask for consent.
