Privacy notice
Tesselan, a service of BEMACS GmbH. Last updated: 13 November 2026.
In short
- This website sets no cookies and has no analytics tools, ads or tracking. Like any website, our host sees technical request data such as your IP address (section 3). If you arrive through a partner's link, we only count sign-ups per partner, anonymously. Its fonts and images come from our own server.
- To join the waitlist you give us your email address and tell us where in Switzerland you live. We confirm your address once, then write to you only about the waitlist and when Tesselan opens.
- Please don't send us sensitive details (health, religion, ethnic origin, sexual orientation, or who you'd like to meet). We'll ask for what we need later, with your clear consent.
- We don't sell your data, and we make no automated decisions about you.
1. Who is responsible
BEMACS GmbH, Albisriederstrasse 56, 8003 Zürich, Switzerland (UID CHE-327.768.012) runs Tesselan and is responsible for your data. Privacy contact: hello@tesselan.com.
2. Who can join
For now the waitlist is open to people living in Switzerland. If you tell us you live elsewhere, we store nothing about you. We only add one to an anonymous count, so we know how much interest there is from outside Switzerland.
You must be 18 or older.
3. What we use your data for, and why we may
| What | Why | Basis |
|---|---|---|
| Visiting this website. Technical request data (IP address, browser type, date and time, page requested), handled by our host | To show you the site and keep it secure | Legitimate interest in running a secure website (GDPR Art. 6(1)(f)); under Swiss law, processing in line with the Data Protection Act's principles |
| Joining the waitlist. Your email address, where in Switzerland you live (a city from our list, a city you type in, or just "elsewhere in Switzerland"), when you signed up, which version of the consent text you saw, and when you confirmed your email. We don't store your IP address. | To confirm your address, tell you about the waitlist and when Tesselan opens, and plan which cities to start in (cities only ever in totals) | Your consent (GDPR Art. 6(1)(a)), which you can withdraw at any time with the unsubscribe link in every email or by writing to us |
| Emailing us. Your address, your name if it appears, and what you write | To read and answer you | Your request (GDPR Art. 6(1)(b)) and our legitimate interest in answering (Art. 6(1)(f)) |
| Business contacts. If we write to an organisation or community group about Tesselan: the public contact address we used, the name of anyone who replies, and the exchange | To ask whether they would share a note about Tesselan, and to respect a no | Our legitimate interest in introducing our service to organisations (GDPR Art. 6(1)(f)); we use only addresses the organisation publishes for contact, write at most twice, and stop as soon as you say no |
Partner links. If you reach us through a link shared by a partner group, the link carries a short code for that group. We only add one to an anonymous count per group when you sign up. We don't store the code with your address. Like any page request, it appears briefly in our host's technical logs (section 7).
We send no newsletters or promotions unless you clearly agree to them first. You don't have to give us any data, but without an email address we can't put you on the waitlist.
4. Please keep sensitive details out
Please don't write to us about your health, religion, ethnic origin, sexual orientation, sex life, or who you'd like to meet. If you do, we won't use it. We'll delete that message and ask you to write again without it.
5. Who receives your data
- Cloudflare, Inc. (USA) hosts this website, runs our sign-up form and stores the waitlist in a database located in the EU. Its network handles your connection, including technical request data such as your IP address, when you load a page or submit the form.
- Brevo SAS (RCS Paris 498 019 298, 9-17 rue Salneuve, 75017 Paris, France) sends the confirmation and waitlist emails. It uses anonymous tracking: it may count how many of our emails are opened or clicked in total, but it doesn't link this to your address or IP address, and we don't use it to profile anyone.
- Google (Google Workspace) is our email provider. Mail to hello@tesselan.com is forwarded by Cloudflare to our Google mailbox.
- Inside BEMACS: only the people who look after the waitlist and the inbox. Others see totals only.
- Authorities, only if the law requires it.
They all process data only for us, under their data processing terms. We don't sell your data or share it with advertisers or partners. Groups that share our link don't receive your data from us.
6. Transfers abroad and safeguards
| Recipient | Countries | Safeguard |
|---|---|---|
| Cloudflare | USA (company); waitlist database in the EU | Cloudflare, Inc. is certified under the EU-U.S. and Swiss-U.S. Data Privacy Frameworks and the UK Extension; standard contractual clauses in Cloudflare's data processing terms also apply |

| Google (email) | Several countries, including the USA | Google LLC is certified under the Swiss-U.S. and EU-U.S. Data Privacy Frameworks and the UK Extension; Google's data processing terms |
7. How long we keep it
- Waitlist: until you unsubscribe or ask us to delete it, and at most 12 months after our last email to you. Sign-ups not confirmed within 7 days are deleted.
- Emails to us: 3 months after our conversation ends, unless you're also on the waitlist.
- Website request data: kept by our host for a limited time it sets. We don't keep it.
8. Your rights
You can ask to see, correct or delete your data, to restrict or object to its use, or to get a copy in a common format. You can withdraw consent at any time, with effect for the future. Write to hello@tesselan.com (to delete, just reply "delete" to any of our emails). We reply within 30 days, free of charge. We may need to check that the request comes from the same email address.

10. Changes
If we change this notice, we'll update this page and its date. If a change matters for how we use your email address, we'll tell you by email first.
