Privacy and cookies

Spaceflightpedia is a non-profit encyclopedia run by Jan Kučera as a one-person project. Contact: info@spaceflightpedia.com. The site is hosted by Roští.cz, whose servers process ordinary operational logs (IP address, request time, browser type) needed to run and secure the service.

We use Google Analytics 4 to learn which entries people read and what is worth writing next. Measurement runs under Google Consent Mode v2 with the default set to “denied”.

Without your consent no analytics cookies are stored — only an anonymous, cookieless signal with no identifier is sent, from which Google derives aggregate estimates. You cannot be identified as an individual from it.

Only after consent does Google Analytics set cookies (_ga, _ga_*) and measurement becomes complete. The data is used in aggregate only; we do not link it to your account and we do not sell it.

Running the site and producing the content is paid for by reader contributions and by advertising. Ads on the site are served by Google AdSense and Ezoic, including their programmatic partners.

Google, Ezoic and their partners use cookies and similar technologies to serve ads. Personalised advertising is not shown without your consent. Consent for Ezoic and its partners is handled by the Ezoic Privacy (Gatekeeper Consent) banner on your first visit; advertising consent for Google defaults to denied and is never obtained automatically.

How Google handles data from partner sites is described in “How Google uses information from sites that use our services”. Ezoic’s own privacy policy describes its practices. You can change your ad preferences at any time in your Google account ad settings, or reopen the Ezoic Privacy banner.

Consent is voluntary and revocable. Withdrawing it is as easy as giving it — use the “Privacy settings” link in the footer of any page.

Your decision is stored locally in your browser (the sfp-consent entry) so the banner does not ask on every visit. It is not a cookie and is never transmitted.

If you create an account we store your email, the name you choose, and your role. These are used for signing in and for attributing proposed edits.

Edit proposals form part of the encyclopedia’s editorial history and stay with the article after approval.

Under the GDPR you have the right to access your data, correct or erase it, restrict processing and object to it. Write to info@spaceflightpedia.com and we will get back to you.

If you are not satisfied with how we handle your request, you may contact the Czech Data Protection Authority (Úřad pro ochranu osobních údajů).
