Cookies Policy
1. What we use
This site does not use HTTP cookies for tracking, advertising, or analytics. We only persist a single value in your browser's localStorage to remember your interface language preference between visits.
2. Storage we set
| Name | Type | Purpose | Lifetime |
|---|---|---|---|
ng-lang |
localStorage | Remembers your selected interface language so you do not need to set it on every visit. | Until you clear it from your browser. |
3. Third parties
We load fonts from Google Fonts (fonts.googleapis.com, fonts.gstatic.com). When your browser fetches these fonts, Google receives standard request metadata (your IP address, user agent, the referring URL). This is governed by Google's privacy policy. The site itself is hosted on Firebase Hosting (Google LLC), which receives the same metadata for delivering pages.
We do not embed analytics scripts, advertising pixels, social-media trackers, or chat widgets on this site.
4. Managing your preferences
You can clear or block local storage at any time using your browser settings:
- Chrome / Edge: Settings → Privacy and security → Cookies and other site data → See all site data and permissions.
- Firefox: Settings → Privacy & Security → Cookies and Site Data → Manage Data.
- Safari: Preferences → Privacy → Manage Website Data.
Clearing the ng-lang entry will reset the language picker to the browser default the next time you visit.
5. Changes
If we ever start using cookies for analytics or other purposes, we will update this page and (where required by law) ask for your consent before doing so.
