This site runs on Cloudflare (Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA). When you visit, Cloudflare automatically processes the technical data your browser sends — IP address, time, requested URL, and browser type — in short-lived server logs. Cloudflare also keeps technical logs of our server code, and your browser may send it automatic error reports if something fails to load. We need this to deliver the site and keep it secure (Art. 6(1)(f) GDPR). Cloudflare may process data in the USA; it is certified under the EU–US Data Privacy Framework (Art. 45 GDPR).
All map tiles — the world map (from OpenFreeMap) and the Mars and Moon maps (from OpenPlanetaryMap) — are served by our own server. Your browser only talks to checktech.space. We fetch the tiles from those services ourselves and pass on none of your data to them: not your IP address, not your browser details.
We use your browser’s local storage for two things: your
dark/light mode choice (key theme) and — only if you
contribute — your contributor ID and access token (key
ct-account). This data stays on your device; only the
access token is ever transmitted, and only to this site, to identify
your contributions. Both are strictly needed for features you chose
(§ 25(2) TDDDG), so no consent banner is required. Remove them any time
by clearing your browser data.
You can suggest edits to project timelines without registering. We ask for no name, no email, and no password. On your first contribution we create a random account ID, an access token (kept in your browser; we store only a hash of it), and a random contributor name that you can change.
For each submission we store the content, your contributor name and ID, timestamps, and a salted hash of your IP address. The hash is used only for rate limits and abuse prevention — we never store your actual IP address. Approved edits become public, credited to your contributor name at the time of approval. Legal basis: our legitimate interest in a moderated, abuse-resistant edit system (Art. 6(1)(f) GDPR). To have your name removed from the public history, email us.
When bot protection is on, submitted edits are checked by Cloudflare Turnstile. The Turnstile widget loads from Cloudflare only while the edit form is open. The check sends your IP address to Cloudflare, and Turnstile may set a cookie of its own — the one exception to “no cookies” above.
Project entries link to external sites (official project pages, Wikipedia). Once you follow a link, that site’s privacy policy applies.
Under the GDPR you can ask us for access to your data (Art. 15), correction (Art. 16), deletion (Art. 17), restriction of processing (Art. 18), and a copy of your data (Art. 20), and you can object to processing based on legitimate interest (Art. 21). Write to the email address above. You can also complain to a data protection supervisory authority (Art. 77).
