Privacy & Cookies

Applies to logoslang.dev.

This is the documentation and marketing site for the Logos language. We keep data collection to a minimum, run our own analytics rather than handing anything to a third party, and never sell your data. There are no advertising or tracking cookies, and nothing loads from another company's servers to watch you.

Analytics we collect

To understand how the site is used, a small first-party script records a page view and a few interactions and sends them to our own server (a Cloudflare function), which stores them in our own database. What is recorded:

• the page you viewed and its title, the site or link that referred you, and your language;
• approximate location derived from your IP address by Cloudflare (country, region, city, and a city-level latitude/longitude that points at the city, not at you) and your network provider;
• your device type, browser, and operating system;
• how long the page was in view, how far you scrolled, and clicks on a few elements (downloads, outbound links, the version picker, the notify form, the playground).

We do not store your IP address, and we do not record your name, email, or anything you type. We do not try to work out who you are, and this data is never sold or shared.

How visits are counted (no cookies)

Instead of cookies we keep two random, meaningless ids in your browser:

• a visitor id in localStorage, so returning visits can be counted. It stays until you clear your browser's site data, holds no personal information, and can be removed any time via your browser's "clear site data" for logoslang.dev.
• a session id in sessionStorage, which groups the pages of one visit and disappears when you close the tab.

Neither is a cookie, neither is shared with anyone, and neither identifies you personally.

Release notifications (only if you sign up)

The home and download pages have an optional "get notified" form. If you submit it, we store the email address you entered, the time you signed up, and which page's form you used, in Cloudflare Workers KV, and use it for exactly one purpose: emailing you when the most important Logos builds are released. It is a low-volume announcement list; you will not be spammed. It is never sold, shared, or used for analytics, and it sets no cookies. The legal basis is your consent, given by submitting the form.

To be removed from the list at any time, contact the maintainers via the GitHub repository and the address is deleted.

Cookies and local storage we use

• theme cookie: remembers your light/dark choice (strictly necessary). ~180 days.
• localStorage visitor id and sessionStorage session id: the anonymous analytics ids described above. No advertising or third-party cookies are set.

Legal basis and your choices

The analytics are first-party, anonymous, and low-impact, used on the basis of our legitimate interest in understanding and improving the site. You can opt out at any time by clearing site data for logoslang.dev or using your browser's private mode or storage controls; the site works fully either way. If you would prefer we did not, contact the maintainers via the GitHub repository.

Where your data goes

The site, the analytics database, and any notification signups are all hosted on Cloudflare, which processes them on our behalf. No analytics data is sent to Google, Microsoft, or any other third party. See Cloudflare's privacy policy.

Your rights

Depending on where you live (for example, the EEA or UK under the GDPR), you may have the right to access, correct, or erase your data, to object to or restrict processing, and to withdraw consent. To exercise these rights, contact the maintainers via the GitHub repository.

Changes

We may update this page as the site evolves; material changes will be reflected here.
