Privacy

The BookOS operating system sends no telemetry. This website uses Microsoft Clarity to analyse browsing only if you accept analytics. You can reject it or withdraw consent at any time.

The data controller is the BookOS Project. For anything related to your personal data or the GDPR, contact [email protected].

Once installed, BookOS sends no data about you, your hardware or your usage to any server. The native apps (Store, Notepad, Clock, Calc, Settings, Launchpad, Control Center) include no tracking.

Updates are checked by contacting the official site. That check includes no identifier beyond that of any normal web browsing.

This website:

• Uses Microsoft Clarity to generate heatmaps and session recordings of public pages, only after you accept the cookie notice. Legal basis: your consent.
• Clarity collects interactions such as clicks and scrolling, together with information about the page. Microsoft receives this data to provide the service. See its privacy statement.
• The integration denies advertising storage and does not load Clarity in the admin panel or during local testing.
• Webfonts are hosted on our own server. Your language and cookie choice are kept in your browser.
• The admin panel uses a necessary session cookie, without tracking.
• The server records requests for security and troubleshooting. Legal basis: legitimate interest in keeping the service available and protected.

Analytics is optional. These are the cookies and local data this website may use:

• bookos-lang (localStorage) — the language you picked, so we don’t have to ask again. Stored only if you accept the notice. Legal basis: your consent. Retention: until you clear your browser data.
• bookos-consent (localStorage) — your answer to this notice. Stored either way, including when you reject: it is precisely what lets us stop asking. Legal basis: our need to evidence the decision. Retention: until you clear your browser data.
• Admin panel session cookie — only under /admin, only for whoever maintains the site. Strictly necessary, exempt from consent, and expires when the browser closes.
• Microsoft Clarity — may use cookies such as _clck and _clsk to recognise visits and group interactions within a session. It loads only with your consent. Microsoft handles the data under its privacy statement.
• Cloudflare — we use Cloudflare as a proxy, CDN and attack protection in front of our server. Every visit passes through their network first, which sees your IP address; they also cache copies of pages and static files on servers worldwide so the site loads faster. We have Bot Fight Mode enabled: if it detects suspicious traffic, it may set its own verification cookies (cf_bm, cf_clearance) in your browser. We don't control these cookies or use them to profile you; they belong to Cloudflare as a data processor. More info in their privacy policy.

If you reject, Clarity will not load and we delete your saved language preference. If you withdraw previous consent, we notify Clarity and stop recording. Your language continues to work through the URL.

You can change your mind at any time with the button below, or by clearing this site’s data in your browser.

If you subscribe with your email, we notify you when we publish a new stable version.

• Data we store: your email address, the sign-up date and the IP address you subscribe from (to prevent abuse and fraudulent sign-ups).
• Legal basis: your consent, which you give by subscribing and can withdraw at any time.
• Retention: we keep your data until you unsubscribe. When you unsubscribe it is deleted. You can do so with the link included in every email.
• Disclosures: we do not share or sell your address to anyone. There are no international transfers of this data.

Under the GDPR you can exercise your rights of access, rectification, erasure, objection, restriction and portability over any data associated with your email, as well as withdraw your consent at any time. Write to [email protected] and we will respond within 30 days. You also have the right to lodge a complaint with the competent supervisory authority (in Spain, the Spanish Data Protection Agency, aepd.es).
