3. Hosting by Cloudflare

This website is delivered by Cloudflare, Inc., 101 Townsend St., San Francisco, CA 94107, USA. When you visit the site, Cloudflare processes technically necessary data so that the site can be displayed and protected against attacks, in particular your IP address, the date and time of access, the requested address and information about your browser and operating system. I do not analyse this data myself.

The legal basis is Art. 6 (1) (f) GDPR. My legitimate interest lies in providing the website securely, quickly and reliably. I have a data processing agreement with Cloudflare.

Data may be transferred to the USA in the process. Cloudflare is certified under the EU-US Data Privacy Framework (adequacy decision of the European Commission, Art. 45 GDPR) and has additionally concluded the European Commission's Standard Contractual Clauses (Art. 46 GDPR). More information: Cloudflare privacy policy.

4. Contact by email

If you send me an email, I process your address and the content of your message in order to reply. The legal basis is Art. 6 (1) (b) GDPR where your enquiry relates to a contract, otherwise Art. 6 (1) (f) GDPR (my interest in answering enquiries). I delete messages once they have been dealt with, unless statutory retention obligations apply.

Emails to info@codonwerk.de are automatically forwarded to my mailbox by Cloudflare (see section 3). Cloudflare processes sender, recipient and content only for forwarding and does not store the message permanently.

My mailbox is hosted by Proton AG, Route de la Galaise 32, 1228 Plan-les-Ouates, Switzerland. Switzerland is covered by an adequacy decision of the European Commission.

5. Features in your browser

The 3D helix runs entirely in your browser. If you allow "Enable tilt" on your phone, your device's orientation data is only used there to move the camera. It never leaves your device and is not stored.

Storage in your browser (local storage)

Simply visiting the site stores nothing on your device. Only when you use one of these features yourself does the site create an entry called codonwerk in your browser's local storage:

This data stays on your device. It is not transmitted to me, to Cloudflare or to third parties, and I cannot see it. The image of your specimen is also generated only in your browser; only you can share it.

The legal basis for storing it is Section 25 (2) No. 2 TDDDG, because storage is strictly necessary to provide the feature you explicitly requested. Where personal data is involved, Art. 6 (1) (b) GDPR applies.

Deletion: On the home page under "Your DNA", "Delete my data" removes everything at once. Alternatively, clear the site data in your browser settings. There is no fixed retention period; the data remains until you delete it.

6. Your rights

You have the right of access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and to object to processing based on Art. 6 (1) (f) GDPR (Art. 21) at any time. An informal email to the address above is sufficient.

7. Right to lodge a complaint

You can lodge a complaint with a data protection supervisory authority. The authority responsible for me is the Unabhängiges Landeszentrum für Datenschutz Schleswig-Holstein (ULD), Holstenstraße 98, 24103 Kiel, Germany, datenschutzzentrum.de.
