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.

2. Data collected when visiting the website

When this website is accessed, our hosting provider Metaliance ISP Systems e.K. (serverdiscounter.com), Friedrichstraße 155, 10117 Berlin, Germany, collects technical data automatically transmitted by the browser on a server located in Germany: IP address, date and time, transferred data volume, user agent, referrer. The website is operated on that server via Coolify / Docker. 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.

On our Odoo comparison pages we additionally offer a detailed report (full comparison table and PDF) after you fill in a short form. We process your company name and business email (required) and, if provided, your current system, company size, industry and your concern (information / contact request / demo). On this basis we deliver the report and handle your enquiry. Two separate consents apply: a mandatory one to receive the report and be contacted about your enquiry (Art. 6 (1) (b) GDPR, pre-contractual measures) and an optional one to receive further information (newsletter; Art. 6 (1) (a) GDPR, consent, revocable at any time). Storage: like other enquiries, until revocation, otherwise 3 years after last contact.

4. Data processors

  • Metaliance ISP Systems e.K. (serverdiscounter.com), Friedrichstraße 155, 10117 Berlin: server hosting in Germany / technical provisioning (operated via Coolify / Docker)
  • 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
  • SuperX GmbH (Superchat): chat widget for customer communication, loaded only with your active consent, see section 8
  • Cloudflare, Inc. (USA): "Turnstile" spam protection on the Odoo comparison form (checks whether a submission is human). Processes the IP address and technical browser signals; cookie-free. Data transfer to the USA is based on the EU-US Data Privacy Framework and/or standard contractual clauses.

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 services that may set cookies or store data on your device (Microsoft Clarity, see section 7, and the Superchat chat widget, see section 8) are loaded only after your active consent via the cookie banner. You can decide on chat and analytics separately and revoke either 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. Superchat chat widget (only with consent)

With your consent we embed the chat widget of SuperX GmbH (Superchat), Germany, so you can message us directly from the website. The widget is loaded only after you actively enable "Chat" in the cookie banner; without consent no Superchat script is loaded and no connection to Superchat is established.

Once loaded, the widget transfers your IP address to Superchat, may set cookies or store data on your device, and processes the content you enter in the chat (message text and any contact details you provide) to handle your enquiry. Purpose: direct customer communication.

Legal basis: Art. 6 (1) (a) GDPR and § 25 (1) TTDSG (your consent for loading the widget and any storage on your device) as well as Art. 6 (1) (b) GDPR (handling your enquiry once you start a chat). The processing by SuperX GmbH as our processor is governed by a data-processing agreement pursuant to Art. 28 GDPR.

Withdrawal: open the "Cookie settings" link in the footer and disable "Chat", or delete the corresponding cookies in your browser. The withdrawal does not affect the lawfulness of processing carried out before.

9. 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.

10. Right to object (Art. 21 GDPR)

You have the right to object at any time, on grounds relating to your particular situation, to processing of your personal data which is based on Art. 6 (1) (f) GDPR (legitimate interests). This applies in particular to the technical logging described in section 2 and to the reach measurement via Umami described in section 6. If you object, we will no longer process the affected personal data unless we can demonstrate compelling legitimate grounds which override your interests, rights and freedoms.

An informal message to info@wissen-beratung.de is sufficient to exercise your right to object.

11. Withdrawal of consent (Art. 7 (3) GDPR)

Where we process data on the basis of your consent (Art. 6 (1) (a) GDPR) — in particular for the contact form (section 3), Microsoft Clarity (section 7) and the Superchat chat widget (section 8) — you have the right to withdraw that consent at any time with effect for the future. The withdrawal does not affect the lawfulness of processing carried out on the basis of the consent before its withdrawal. For consent given via the cookie banner, use the "Cookie settings" link in the footer; for any other consent an informal email to info@wissen-beratung.de is sufficient.

12. 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.

13. 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.
