2. General information on data processing

Personal data is processed only to the extent necessary to provide a functional website and the content and services offered. Processing of personal data generally takes place only with consent or where permitted by law.

3. Hosting

This website is operated on servers of an external hosting provider. When you access the website, information is automatically transmitted to the server and stored in server log files. This includes:

• IP address of the requesting device
• Date and time of access
• Name and URL of the file retrieved

4. Contact form and email

When you use the contact form or contact me by email, the information you provide (name, email address, message) is processed to handle your inquiry. The data is processed on the server and forwarded by email to yannic@schroeer.tech.

Legal basis: Art. 6 (1) lit. b GDPR (pre-contractual measures) or Art. 6 (1) lit. f GDPR (legitimate interest in responding to inquiries). Data is shared with third parties only where necessary for contract performance or required by law.

5. Cookies and storage technologies (§ 25 TDDDG)

This website uses cookies and similar storage technologies. Pursuant to § 25 (1) TDDDG (German Telecommunications Digital Services Data Protection Act), storing information on an end device or accessing information stored there is permitted only with express consent.

Technically necessary cookies are set without consent pursuant to § 25 (2) TDDDG because they are strictly required for the operation of the website. This includes storing cookie consent (localStorage).

Optional cookies and analytics technologies are activated only after express consent via the consent banner. Consent can be withdrawn at any time by deleting browser storage data.

6. Web analytics with PostHog

This website uses PostHog, a web analytics service. PostHog is operated on EU servers (PostHog Cloud EU, Frankfurt). Processing takes place only after prior consent via the consent banner.

PostHog collects usage data such as pages visited, time on page, device information, and interactions. No personal data is transferred to third parties outside the EU. Data is used solely to analyze and improve the website.

Legal basis: Art. 6 (1) lit. a GDPR (consent) in conjunction with § 25 (1) TDDDG.

7. Google Ads (conversion tracking)

This website uses Google Ads, a service of Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland ("Google"), to measure the effectiveness of advertisements. Use takes place only after express consent via the consent banner (category "Marketing").

After consent, the Google tag (gtag.js) is loaded. When you visit the website, Google may set a cookie with a click identifier (Google Click Identifier, "GCLID") and additional device data if the visit came through a Google Ads ad. In addition, conversion events (e.g. submitting the contact form) are transmitted server-side to Google via the Google Ads API. Pseudonymized contact data hashed with SHA-256 (email, name) is transmitted to match previous clicks to conversions ("Enhanced Conversions for Leads").

Transmission goes to Google servers in the USA. Google has committed to an adequate level of data protection under the EU-US Data Privacy Framework (EU Commission adequacy decision of 10 July 2023).

Legal basis: Art. 6 (1) lit. a GDPR (consent) in conjunction with § 25 (1) TDDDG. Consent can be withdrawn at any time with effect for the future via cookie settings.
