What cookies we use

Strictly necessary (always on)

• sf-theme. Stores your preference between dark and light theme so the site doesn't flash on every page load. Stored as localStorage, not technically a cookie. No personal data.
• sf-lang. Stores your preferred interface language (EN, ES). Stored as localStorage, not technically a cookie. No personal data.

Optional (only if you opt in)

The following are not currently used. They are listed here so you know what to expect if and when they are added:

• Analytics. If privacy-respecting analytics are added, they will be disclosed here with the specific cookies set.
• Advertising. If display advertising (for example, Google AdSense) is added, the advertising network may set cookies and a consent banner will be shown before any advertising cookies are placed.

Controlling cookies

You can clear cookies and localStorage from your browser settings at any time. Doing so will reset your theme and language preferences to defaults. The site will continue to function.

Third-party cookies

We load fonts from Google Fonts. Google may set cookies as part of that request. See Google's privacy policy for details.

Changes

If we add or remove cookies, this page will be updated and the "Last updated" date will change.
