2. Collection and Storage of Personal Data
When you visit our website, your browser automatically sends information to the server of our website. This information is temporarily stored in a log file. The following information is collected without any action on your part and stored until it is automatically deleted:
- IP address of the requesting computer
- Date and time of access
- Name and URL of the retrieved file
- Website from which access is made (referrer URL)
- Browser used and, if applicable, the operating system of your computer
- Name of your access provider
The data mentioned is processed by us for the following purposes:
- Ensuring a smooth connection to the website
- Ensuring convenient use of our website
- Evaluating system security and stability, as well as for other administrative purposes
The legal basis for data processing is Art. 6(1)(f) GDPR. Our legitimate interest follows from the purposes of data collection listed above.
The log files are rotated daily and automatically deleted after no more than 15 days. Longer retention only takes place if there are specific indications of an attack or misuse and the data is required to investigate it. Our website is operated on a virtual private server (VPS) provided by STRATO GmbH, Otto-Ostrowski-Straße 7, 10249 Berlin, in data centres located in Germany. We manage the web server (nginx), including its log files, ourselves; STRATO merely provides the server infrastructure.
3. Email Contact
If you send us inquiries by email, your details, including the contact information you provide, will be stored for the purpose of processing the request and in the event of follow-up questions. We do not share this data without your consent.
If your enquiry relates to the performance of a contract or is necessary for pre-contractual measures, the legal basis is Art. 6(1)(b) GDPR. In all other cases, processing is based on our legitimate interest in effectively handling enquiries addressed to us (Art. 6(1)(f) GDPR).
The data transmitted to us will remain with us until you request deletion, revoke your consent to storage, or the purpose for storing the data no longer applies (e.g. after your request has been fully processed).
4. Cookies
This website does not use tracking cookies or third-party cookies. We only store two pieces of technically necessary information on your device: your language preference (cookie “devtank42_lang”, stored for 12 months, plus an identical localStorage entry as a fallback) and the fact that you have acknowledged our cookie notice (localStorage entry “devtank42_cookie_consent”, automatically deleted after 12 months). The localStorage entry for your language preference remains until you delete it. These entries contain no personal data and are not transmitted to third parties. The legal basis for storing this information on your device is Section 25(2) No. 2 TDDDG (German Telecommunications Digital Services Data Protection Act), as it is strictly necessary to provide the website you have expressly requested; consent is therefore not required. You can delete these entries at any time via your browser settings.
5. Web Analytics with Umami
To analyse access to our website statistically, we use Umami – a self-hosted, privacy-friendly open-source web analytics tool. Umami runs on our own infrastructure under the subdomain analytics.devtank42.de; no data is transferred to third parties.
Umami operates entirely without cookies and does not store any information on your device. No personal profiles are created and visitors are not recognised across websites. Only anonymised usage data is collected, such as the pages visited, referrer URL, browser and device type, and an approximate location based on the shortened IP address, which is not stored.
The legal basis is Art. 6(1)(f) GDPR; our legitimate interest lies in the statistical analysis and needs-based optimisation of our website. As no cookies are set and no personal data is stored permanently, no consent is required. You may object to this anonymous web analytics at any time by preventing the analytics script from loading in your browser (e.g. using a script or tracking blocker).
6. External Services
This website uses the font Hanken Grotesk, which is hosted locally on our server. No connection to external font servers takes place. Icons are displayed exclusively using SVG resources embedded server-side.

10. Currency and Changes to this Privacy Policy
