Public pages

heartdok.io sets no cookies, runs no analytics, shows no ads and loads nothing from other sites. Cloudflare, which hosts it, keeps standard request logs (address, time, page and browser) to run and protect the service.

The study workspace

The workspace at arch.heartdok.io is private. Cloudflare Access checks every visit, and only invited accounts get in. It keeps study progress for its own user and shares nothing with anyone.
