The short version

This site sets no cookies and uses no analytics or advertising tools. Fonts are served from our own host. We only receive personal data when you join the waitlist or write to us.

Visiting this site

The site is hosted by Cloudflare, Inc. To deliver and protect it, Cloudflare processes technical data such as your IP address, browser type and the time of your request. The legal basis is our legitimate interest in a secure, working website (Art. 6(1)(f) GDPR).

Waitlist

When you join the waitlist, we store your email address, the role you picked (if any) and the time you signed up. We use this only to tell you about early access to Tsuna and to understand who is interested. The legal basis is your consent (Art. 6(1)(a) GDPR), which you give by submitting the form.

The waitlist is stored in a database run by Cloudflare. We are also notified of each signup by email through Resend, Inc. Both act as our processors. We keep your entry until early access has opened and you have been invited, or until you ask us to remove it, whichever comes first. To leave the waitlist, email [email protected].

Writing to us

If you email us, we process your address and your message to answer you. The legal basis is our legitimate interest in answering enquiries (Art. 6(1)(f) GDPR) or steps taken at your request before a possible contract (Art. 6(1)(b) GDPR).

Transfers outside the EU

Cloudflare and Resend are based in the United States, so data may be processed there. These transfers rely on the safeguards the GDPR provides, such as EU standard contractual clauses or an adequacy decision.

Your rights

You can ask for access to your data, and for it to be corrected, deleted, restricted or handed over to you. You can object to processing based on legitimate interests, and withdraw any consent at any time. Just email us. You can also complain to a data protection authority, for example the Bavarian State Office for Data Protection Supervision (BayLDA).
