Privacy policy

Updated: 21 May 2026

This policy explains how we handle your personal data when you join the Cillero waitlist. It is written in accordance with Regulation (EU) 2016/679 (GDPR) and Spanish Organic Law 3/2018 on Data Protection (LOPDGDD).

1. Data controller

2. What we collect

Only your email address, which you provide voluntarily through the waitlist form. We do not collect your name or a persistent IP address. We only collect browsing data if you voluntarily enable advertising measurement (see section 8).

3. Purpose

To notify you by email when our beta opens. We do not use your address for any other purpose and will not send you unsolicited promotional messages.

4. Legal basis

Processing is based on your explicit consent (Art. 6(1)(a) GDPR), given when you submit the form. You may withdraw consent at any time without affecting the lawfulness of prior processing.

5. Recipients and processors

Emails are stored with Resend (Resend Inc., USA), acting as data processor. The international transfer is covered by the Standard Contractual Clauses approved by the European Commission. The site is hosted on Cloudflare (Cloudflare, Inc.) under the same regime.

To measure site traffic we use Plausible Analytics (Plausible Insights OÜ, Estonia, EU). It is a cookieless analytics tool that produces only aggregate statistics (pageviews, traffic sources) and does not store your IP address or build individual profiles. Processing happens entirely within the European Union.

If you accept advertising-measurement cookies (see section 8), we load the Meta Pixel, operated by Meta Platforms Ireland Ltd (Ireland, EU). Only in that case does Meta receive data about your browsing on this site, to measure how well our ads perform. If you do not accept, the pixel is never loaded and Meta receives nothing.

We do not share your email with any other third parties.

6. Retention

We keep your email on the waitlist until (a) we open the beta and send you the invitation, or (b) you ask us to delete it — whichever comes first. If you later register as a product user, the product privacy policy will apply.

7. Your rights

You can exercise the rights of access, rectification, erasure, restriction, portability, and objection at any time by writing to [email protected]. We will respond within one month.

If you believe processing does not comply with the law, you may file a complaint with the Spanish Data Protection Agency (AEPD) (aepd.es).

8. Cookies and tracking

Basic audience measurement is handled by Plausible Analytics (see section 5), which works without cookies or persistent identifiers. This analytics is always on and needs no consent, as it cannot identify you.

Optionally, we use the Meta Pixel to measure how well our advertising performs. The pixel does use cookies and is only loaded if you give explicit consent in the banner shown when you visit the site. It is off by default. You can reject it, and you can change your choice at any time by clearing the site's data in your browser. If you reject it, the site keeps working normally.

9. Changes

We may update this policy if processing changes. For material changes we will email you in advance.
