What we do with your email
You join the waitlist and leave us your email. This is everything that happens with it, no fine print.
Last updated: August 5, 2026
Who is responsible for your data
Darío Guerra Aragón, in a personal capacity, from the United States. For anything to do with your data, write to [email protected].
What we collect
Your email address, the date you signed up and which form on the site you used. Nothing else.
This site uses no cookies, no analytics and no trackers. There are no advertising pixels or social media buttons, and the fonts are served from our own domain, so your browser talks to nobody else while you visit.
Even though Reven is a health tool, this site collects no health data about you.
What we use it for
To let you know when Reven opens access and, in the meantime, to tell you now and then how the project is coming along. Nothing else.
We do not sell your email, we do not rent it and we do not pass it to anyone for advertising.
On what basis
On your consent: you give it when you submit the form. You can withdraw it whenever you want, from the unsubscribe link in every email we send or by writing to [email protected]. Leaving is as easy as joining.
Where it is stored
In two places, both providers working on our behalf and unable to use your email for their own purposes:
- Cloudflare, which hosts this site and keeps our copy of the list.
- Brevo, the tool we send the emails with. It is a French company and stores the data in the European Union.
Since we are in the United States and Brevo is in Europe, your email crosses borders. Both providers rely on the safeguards set out for those transfers.
For how long
Until Reven opens access and we let you know, or until you unsubscribe, whichever comes first. When you unsubscribe we delete your email from both copies.
If the project never launches, we delete the whole list and tell you before we do.
What you can ask us for
To tell you what we hold about you, to correct it, to delete it or to send it to you in a file. Write to [email protected] and we will reply within 30 days at the most. It costs nothing and we will not treat you differently for asking.
If you live in the European Union or the United Kingdom, the GDPR gives you these same rights and you can also complain to the data protection authority in your country.
Minors
The waitlist is not meant for anyone under 16. If we receive an email address from someone that age, we delete it as soon as we know.
If this changes
We will update the date above. If the change really affects you, we will tell you by email before it applies.
