The essentials
- This website sets no cookies and loads nothing from other providers: no fonts, no scripts, no videos from third-party servers.
- There is no analytics service and no counter.
- We receive data from you only when you write to us.
Visits and hosting
The website runs on our own server at Contabo GmbH in Germany. In front of it stands the network of Cloudflare, Inc., 101 Townsend Street, San Francisco, CA 94107, USA: it receives your request, usually in a data centre near you, wards off attacks and passes it on to our server. The technically necessary details are processed in doing so: your IP address, date and time, the address requested, your browser's identification and the page you came from.
Our web server keeps a log of this to detect attacks and find errors, and deletes it after 14 days at the latest. The legal basis is Art. 6(1)(f) GDPR; our interest is secure and reliable operation. Cloudflare and Contabo work on our behalf. More about Cloudflare: www.cloudflare.com/privacypolicy
Cookies and storage in your browser
This website sets no cookies. Your browser keeps only what you choose yourself: light or dark and whether motion is paused. This is necessary to keep the appearance you chose (Section 25(2) no. 2 of the German TDDDG). The values stay in your browser and are not sent to us; you can delete them there at any time.
Contact form and email
If you write to us through the contact form or by email, we process your email address and your message in order to answer you. Messages from the form are sent by email to our mailbox. If that fails, we store them on our server until we have read them. Mailbox and server are at Contabo GmbH in Germany.
Against spam we use a hidden field, a timing check and a daily limit, not a third-party service. The legal basis is Art. 6(1)(f) GDPR; our interest is to answer enquiries. Where your message concerns a contract with us, it is Art. 6(1)(b) GDPR. We delete enquiries once they are settled, after twelve months at the latest, unless a statutory retention duty applies.
Links to other sites
This website links to the sites of our projects, for example daynori.mizustudio.dev. Only when you follow a link does the other site receive data from you. Its own privacy policy applies there.
Service providers
The following work on our behalf and on our instructions (Art. 28 GDPR):
- Cloudflare, Inc., USA: protecting and forwarding requests to the website.
- Contabo GmbH, Munich, Germany: our server in Germany with the website, the contact form and our mailbox.
We do not sell data and pass it on to no one else, unless the law obliges us to.
Countries outside the European Union
Cloudflare is certified under the EU–U.S. Data Privacy Framework, for which the European Commission has adopted an adequacy decision (Art. 45 GDPR). Cloudflare receives requests to the website in data centres in many countries.
How long we keep data
- Web server log: 14 days at most.
- Enquiries: until they are settled, twelve months at most.
Your rights
You have the right of access (Art. 15 GDPR), to rectification (Art. 16), to erasure (Art. 17), to restriction of processing (Art. 18) and to data portability (Art. 20). Write to us at support@mizustudio.dev.
You can also lodge a complaint with a data protection supervisory authority (Art. 77 GDPR), for example the authority where you live.
Your right to object
Where we process data on the basis of a legitimate interest (Art. 6(1)(f) GDPR), you can object at any time on grounds relating to your particular situation (Art. 21 GDPR). We then stop processing the data, unless there are compelling legitimate grounds for it or the processing serves legal claims.
Voluntary details, no automated decisions
You are not obliged to give us data. Without your email address, however, we cannot answer you. No decisions are made here that are taken solely by automated means and affect you legally (Art. 22 GDPR).
Changes
We update this policy when the website or the law changes. The version on this page applies.
