Independent digital studio
Ideas worth thinking through carefully.
CMZen Digital is the studio of Christian Mäusezahl. The thematic focus is deliberately kept open: at the center is careful craft, not a single industry. The first project: ChessLynx, a chess app for children that he is especially excited about right now.

Approach
How we work
People first, not metrics
No growth at any price, no tracking or advertising tricks. What we make has to answer to the people who use it, not to a dashboard.
Data stays minimal
Only what a function really needs is processed, whatever the project.
Craft, not templates
Illustration, interaction and text are made iteratively and in detail: better one chapter done thoroughly than ten done superficially.
The first project
What we are working on right now
ChessLynx
ChessLynx is a chess-learning app for children aged 5 and up, designed from the ground up for independent learning without reading. Lux the lynx explains through speech, pictures and demonstrated moves. Children take an active part and deepen their understanding, from the first piece movements to tactical ideas and full games. Parents can join in at any time and manage daily play time. ChessLynx is in development.

In short
This site sets no cookies and uses no analytics or marketing tools and no content from third parties. You do not have to enter anything to read it.
Hosting and server logs
The site is hosted by ALL-INKL.COM – Neue Medien Münnich, Hauptstraße 68, 02742 Friedersdorf, Germany, which acts as our processor (contract under Art. 28 GDPR). To deliver the site, the host first processes the full IP address. It also processes technically necessary access data: date and time, page requested, browser and operating system, referring page. Before storage in the access logs, the IP address is truncated (11.22.33.44 becomes 11.22.0.0). Truncation reduces identifiability; we do not treat the logs as necessarily anonymous for that reason alone. The logs are deleted automatically after 7 days. The purpose is secure and trouble-free operation of the site; the legal basis is our legitimate interest in it (Art. 6(1)(f) GDPR). The data is processed in Germany.
Fonts
The fonts are hosted on our own server. No connection to Google or other font providers is made when you visit.
If you write to us at support@cmzen-digital.com, we process your email address, your name (if given) and the content of your message to answer your inquiry. We handle contract-related inquiries under Art. 6(1)(b) GDPR and other general inquiries based on our legitimate interest in responding (Art. 6(1)(f) GDPR). Art. 6(1)(c) GDPR applies when we fulfill data-protection requests or other legal obligations. The mailbox is also hosted by ALL-INKL.COM in Germany. We delete completed inquiries no later than 90 days after handling is finished, provided no further processing purpose or statutory retention obligation remains. Where further retention is necessary, we limit it to that purpose and delete the message when the purpose ends or the statutory period expires. We do not pass the information on to third parties.
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 legitimate interests (Art. 21). These rights apply subject to their respective legal requirements. An informal email to support@cmzen-digital.com is enough. You can also lodge a complaint with a data protection supervisory authority (Art. 77 GDPR); the authority responsible for us is the Bavarian State Office for Data Protection Supervision (Bayerisches Landesamt für Datenschutzaufsicht), Promenade 18, 91522 Ansbach, Germany.
