Privacy policy

1. Who is responsible for your data

Controller

Gustavo Martín, trading as Tesselium Labs

Privacy contact

privacy@tesselium.com

2. What data we process and why

Contact form. Name, email, company or project (optional) and message. We use them to reply to your message and, if you ask about a project, to prepare a proposal.

Call booking. When you book a call through Cal.com, the name, email, time and notes you provide. We use them to hold the call.

Security. The form is protected by Cloudflare Turnstile, which analyses technical signals from your browser to tell people from bots.

Statistics. We use Cloudflare Web Analytics, which counts visits without cookies and without identifying you.

We do not use your data for advertising, we do not sell it and we do not make automated decisions about you.

3. Legal basis

Project enquiries and proposals. Steps taken at your request before a possible contract (Article 6(1)(b) GDPR).

Other messages and call bookings. Our legitimate interest in replying to you (Article 6(1)(f) GDPR).

Security and statistics. Our legitimate interest in protecting the website and understanding how it is used (Article 6(1)(f) GDPR).

4. How long we keep it

Messages and bookings that do not lead to a contract are deleted 12 months after the last contact. If they lead to a contract, the data are kept for as long as the contract lasts and afterwards for the periods required by tax and commercial law.

5. Who processes it on our behalf

The following providers act as data processors under a data processing agreement.

• Cloudflare (hosting, contact form, security and statistics)
• Cal.com (call booking)
• Google (email and video calls through Gmail and Google Meet)

Some of them may process data outside the European Economic Area, in particular in the United States. In those cases, transfers rely on the EU-US Data Privacy Framework or on the European Commission's standard contractual clauses.

We do not share your data with anyone else unless the law requires it.

6. Your rights

You can request access to your data, its rectification or erasure, the restriction of or objection to its processing, and its portability, by writing to privacy@tesselium.com. If you believe your rights have not been respected, you can file a complaint with the Spanish Data Protection Agency (www.aepd.es).

7. Required fields

Fields marked with an asterisk are needed to reply. Without them, we cannot answer your message.
