Privacy policy

This is an English translation provided for convenience. The Spanish version (política de privacidad) is the legally binding one, as the site operates under Spanish law.

The short version, no fine print: this site uses no cookies, has no user accounts, sells no data to anyone and shows no ads. The only personal data it processes is your Telegram chat identifier if you voluntarily sign up for alerts, plus the technical logs any web server generates. The full detail follows.

Data controller

Controller: Rafael Devos Cerezo
Tax ID (NIF): 27323711X

What data is processed and why

1. Telegram alerts (only if you sign up)

If you start a conversation with the alerts bot (@BlockPulseAlertsBot), we store only your numeric Telegram chat identifier (chat_id) — not your name, username, phone number or anything else. It is the bare minimum needed to send you the alert message.

Purpose: notifying you when the Score phase changes.
Legal basis: your consent (signing up is your own voluntary action: messaging the bot).
Retention: until you unsubscribe. Sending the /stop command to the bot deletes your record entirely from the database — no unsubscribe history is kept.
Note about Telegram: communication happens through the Telegram platform, which processes your data under its own privacy policy, independent of this site.

2. Server technical logs

Like any web server, ours automatically logs technical data for each request: IP address, date and time, requested URL and browser user agent.

Purpose: security (abuse detection, per-IP rate limits) and technical diagnostics.
Legal basis: legitimate interest in keeping the service secure and operational.
Retention: the technically necessary time for those purposes; logs are rotated and deleted.
The server is hosted in the European Union (Germany, provider Contabo GmbH). This data is not transferred outside the EU.

3. Web analytics (cookieless)

We use Cloudflare Web Analytics in its cookieless variant: it sets no cookies, uses no persistent identifiers or fingerprinting techniques, and produces only aggregate statistics (page views, country of origin, browser type). It cannot identify you or track you across sites.

4. Bitcoin addresses you analyse in the tools

Addresses you enter in the analyser are public Bitcoin blockchain data. The site queries them against public sources to generate the analysis and may temporarily cache the public data retrieved, to speed up future responses. They are not linked to your identity or your IP beyond the technical logs described in section 2.

Cookies and local storage

This site sets no cookies, first-party or third-party. It uses the browser's local storage (localStorage) for a single technical purpose: keeping the latest Score response on your own device so the page loads without flickering. That data never leaves your browser, contains no personal information, and you can delete it at any time from your browser settings. Being strictly technical storage, it requires no consent — which is why you will not see a cookie banner.

What we do NOT do

No user accounts or registration forms.
No newsletters or emails (we do not collect email addresses).
No selling or sharing of data with third parties.
No advertising or ad trackers.
No user profiling.

Your rights

You can exercise your rights of access, rectification, erasure, objection, restriction of processing and portability at any time by writing to contacto@blockpulseanalytics.com. For Telegram alerts, the most direct route is the bot itself: /stop deletes your data instantly, no need to write to us.

If you believe the processing does not comply with the regulations, you can file a complaint with the Spanish Data Protection Agency (www.aepd.es).

Changes to this policy

If the site adds features in the future that change this data processing, this policy will be updated before they go live, and the last-updated date (at the bottom) will reflect it.
