Privacy policy

Last updated: March 2026

1. Who is responsible?

This site, tüftle.li, is operated by Lex (full name available upon request). If you have any questions, you can reach me at hello@tüftle.li.

2. What data is collected?

When you subscribe to the launch notification list, I collect:

No other data is collected. I do not use cookies, tracking pixels, or analytics tools.

3. Why is it collected?

The sole purpose is to send you a single notification when tüftle.li launches. I will never use your email for anything else.

4. Legal basis (GDPR Art. 6)

I rely on your explicit consent (Art. 6(1)(a) GDPR), which you give by checking the consent box and submitting the form.

5. Where is data stored?

Data is stored in Cloudflare Workers KV (a secure, serverless database) hosted in the European Union. Cloudflare is certified under the EU-US Data Privacy Framework.

6. How long is data kept?

Until the launch of tüftle.li. After the notification is sent, all email addresses will be deleted. If you unsubscribe earlier, your data is removed immediately.

7. Your rights

Under the GDPR, you have the right to:

To exercise any of these rights, simply reply to any email from me or write to hello@tüftle.li. I will respond within 30 days.

8. How to withdraw consent

You can withdraw your consent at any time by replying "unsubscribe" to any email, or by emailing me directly. Your data will be deleted immediately.

9. Data sharing

I do not share, sell, or rent your data to anyone. Ever. The only third party involved is Cloudflare, which acts as a data processor (they store the data on my behalf).

10. Changes to this policy

If this policy changes, I will update this page. If the changes are significant, I may notify subscribers by email.
