Privacy policy
Gartenzettel is built so that as little data as possible arises. Your region and your plant selection never leave your device — there is no account, no sign-in and no synchronisation.

No cookies
This website sets no cookies. No consent banner is required because no consent-requiring technologies are used.
Data that stays on your device
Your selection and settings are stored solely in your browser (localStorage). This data is never transmitted and the operator cannot see it. You can delete it at any time through your browser settings.
- gartenzettel-garden — your federal state, your climate band and your list of selected plants
- gartenzettel-theme — your choice between light and dark theme
Hosting and server log files
The website runs on servers of Hetzner Online GmbH, Industriestr. 25, 91710 Gunzenhausen, Germany. A data processing agreement under Art. 28 GDPR is in place with Hetzner.
When you load a page, the web server processes technically necessary connection data (IP address, time, requested resource, status code, user agent). The legal basis is Art. 6(1)(f) GDPR; the legitimate interest is secure and reliable operation. These logs are deleted after 14 days at the latest.
Audience measurement with Matomo
Audience measurement uses the self-hosted open-source software Matomo on our own infrastructure. No cookies are set, IP addresses are truncated, no data is merged with other sources and nothing is passed to third parties. Your browser’s "Do Not Track" setting is respected.
The legal basis is Art. 6(1)(f) GDPR (legitimate interest in data-minimising statistics about use of the service).
Technical usage counters
For operational monitoring the server counts anonymous events, such as how often a plant page was opened or a calendar exported. These counters contain no personal data, no IP addresses and nothing about which plants any individual selected. "Do Not Track" is respected here too.
Contacting us and the contact form
If you write to kontakt@gartenzettel.de or use the contact form, the information you provide is processed in order to handle your enquiry (Art. 6(1)(f) GDPR — legitimate interest in answering enquiries). Via the form that is your name, your email address and the text of your message. Messages are deleted once they are no longer needed, and at the latest six months after the enquiry has been dealt with.
Delivery: messages from the contact form are delivered via the email service rapidmail GmbH (Augustinerplatz 2, 79098 Freiburg im Breisgau, Germany), acting as a processor, and arrive in a mailbox operated by Proton AG (Geneva, Switzerland). Switzerland is covered by an adequacy decision of the EU Commission (Art. 45 GDPR). No further transfer to third countries outside the EEA takes place.
Spam protection (ALTCHA): so that the form cannot be abused by machines, your browser solves a small computation in the background (proof of work). The software for this runs on the same server as this site. No cookies are set, no data is passed to third parties, and nothing is stored on or read from your device.
Your plant selection and your region reach none of these providers — they stay exclusively in your browser. No newsletter is sent.
Your rights
You have the right of access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and objection (Art. 21 GDPR). You also have the right to lodge a complaint with a supervisory authority.
Because your selection is stored only locally, the operator generally holds no data about an individual that could be the subject of an access request.
