Cookie policy
Last updated: 19 October 2026
1. What cookies are
Cookies are small files a website stores in your browser. Similar technologies, such as the browser's local storage, serve the same purpose. This policy covers both and follows article 22.2 of Spain's Law 34/2002 (LSSI-CE) and the GDPR.
2. What this site stores
This site does not use advertising, profiling or social-media cookies. It only stores the following:
| Name | Owner | Purpose | Duration | Type |
|---|---|---|---|---|
| btcscore.theme, btcscore.lang | The Bitcoin Score (own) | Remember the theme and language you chose. | Until you delete it | Preference(exempt from consent) |
| btcscore.chart.* | The Bitcoin Score (own) | Remember which series you left visible on each chart. | Until you delete it | Preference(exempt from consent) |
| btcscore.cookies | The Bitcoin Score (own) | Remember whether you accepted or rejected analytics, so we don't ask again. | Until you delete it or change your choice | Technical(exempt from consent) |
| btc_score_visitor_id | The Bitcoin Score (own) | Anonymous random ID to tell new visitors from returning ones in our visit statistics. Not linked to any real identity. | Until you delete it or withdraw consent | Analytics(requires consent) |
If you accept analytics, we also send your IP address to ipapi.co (or, if it fails, ipwho.is) to find out which country you are visiting from. We only keep the country, never the IP. If you reject, no request is made to these services.
The admin area (/admin and /login) uses a Supabase session cookie, strictly necessary to keep the administrator signed in. Visitors never get it.
3. When they are set
Preference and technical entries are saved when you make the choice they remember. The analytics ID and the country lookup only happen if you accept in the cookie notice. If you reject or ignore the notice, your visit is still counted, but anonymously: without the ID and without the country.
4. How to change or withdraw your consent
You can change your choice at any time, as easily as you made it, with this button. It is also in the footer of the site. Withdrawing consent deletes the analytics ID from your browser.
You can also block or delete cookies and site data from your browser's privacy settings.
