Privacy policy

This English version is a courtesy translation. The legally binding version is the German "Datenschutzerklärung" served under wissen-beratung.de. Data processing is governed by EU GDPR and German data-protection law regardless of the domain you visit.

1. Controller

WISSEN BERATUNG
Owner: Tobias Wissen

2. Data collected when visiting the website

When this website is accessed, the hosting provider (Coolify / Docker hosting in Germany) collects technical data automatically transmitted by the browser: IP address, date and time, transferred data volume, user agent, referrer. These data are used exclusively for technical provisioning and are deleted after a maximum of 14 days.

Legal basis: Art. 6 (1) (f) GDPR (legitimate interest in the stable operation of the website).

3. Contact form

When you reach out via the contact form we store name, email, optionally company and phone number, and your message. These data are stored in our CRM system (CRM 19, hosted in Germany) and used to handle your enquiry.

Legal basis: Art. 6 (1) (a) GDPR (consent) and Art. 6 (1) (b) GDPR (pre-contractual measures). Storage duration: until consent is revoked, otherwise 3 years after last contact.

4. Data processors

  • Coolify / Docker hosting (servers in Germany) — technical provisioning
  • CRM-System (eigener Server in Deutschland) — Speicherung der Kontaktanfragen
  • Optional: Slack / Mattermost webhook — internal notification only, no personal content
  • Umami Analytics (self-hosted on our own server in Germany, analytics.wb-crm.net) — cookie-free reach measurement, see section 6
  • Microsoft Clarity (Microsoft Corporation, USA) — heatmaps and session replays, only with your active consent, see section 7

Data-processing agreements (DPA) pursuant to Art. 28 GDPR are in place with all processors.

5. Cookies

We use cookies sparingly. Strictly necessary entries — for example rate-limiting for forms and a localStorage entry that remembers your cookie-banner decision — are exempt from the consent requirement under § 25 (2) TTDSG, because they are required to provide functionality you actively requested.

Optional cookies (Microsoft Clarity for heatmaps and session replays — see section 7) are loaded only after your active consent via the cookie banner. You can revoke consent at any time using the "Cookie settings" link in the footer.

6. Reach measurement (Umami Analytics)

For anonymous reach measurement we use Umami Analytics, self-hosted on our own server in Germany (analytics.wb-crm.net). Umami does not set cookies and does not use cross-site identifiers. IP addresses are processed only in memory to generate an anonymous, salted hash; no IP addresses or personal identifiers are stored. Processed information: anonymized page views, referrer, device type, browser, coarse country/region based on the hashed IP.

Legal basis: Art. 6 (1) (f) GDPR (legitimate interest in understanding the usage of our website to improve it). Since no information is stored on or read from your device, § 25 TTDSG does not apply and no consent is required. You may object at any time by sending an email to info@wissen-beratung.de.

7. Microsoft Clarity (heatmaps & session replays — only with consent)

With your consent we use Microsoft Clarity (Microsoft Corporation, One Microsoft Way, Redmond, WA 98052, USA) for heatmaps and anonymised session replays. The goal is to understand where visitors get stuck on our pages so we can improve them. Clarity sets first-party cookies (e.g. _clck, _clsk) and records aggregated usage information: mouse movements, scroll depth, clicked elements, screen size, browser, coarse location, and pseudonymised session identifiers. Form input fields are masked by default.

Legal basis: Art. 6 (1) (a) GDPR (consent) and § 25 (1) TTDSG (consent for storing information on terminal equipment). Without your active consent via the cookie banner, no Clarity script is loaded and no Clarity cookies are set.

Third-country transfer: Clarity data is processed by Microsoft Corporation in the USA. Microsoft is certified under the EU-US Data Privacy Framework (DPF); we additionally rely on the EU Standard Contractual Clauses pursuant to Art. 46 (2) (c) GDPR.

Storage duration: Clarity cookies have a maximum lifetime of 1 year (renewed on each visit). Session replays are retained by Microsoft for a maximum of 1 year and are then deleted automatically.

Withdrawal: open the "Cookie settings" link in the footer and choose "Decline", or delete the Clarity cookies in your browser. The withdrawal does not affect the lawfulness of processing carried out before. More information on Microsoft Clarity privacy: learn.microsoft.com/clarity.

8. Your rights

You have the right to access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction (Art. 18), data portability (Art. 20) and to object (Art. 21). You may also lodge a complaint with the competent supervisory authority.

To exercise your rights, an informal email to info@wissen-beratung.de is sufficient.

9. Fonts

The fonts Inter and Montserrat are served locally from our server. No connection is established to Google Fonts CDN or similar third-party providers.

10. Right to complain

Without prejudice to any other legal remedy, you have the right to lodge a complaint with a data-protection supervisory authority. Competent authority is: Landesbeauftragte für den Datenschutz Niedersachsen, Prinzenstraße 5, 30159 Hannover, lfd.niedersachsen.de.
