Privacy Policy

1. Controller

Hex Engine – Alex Hug und Max Wagenfeldt GbR, Gustav-Müller-Platz 5, 10829 Berlin.
Email: contact@hexengine.de

2. Email gate (demo access)

To unlock the demo we collect the data you provide (first/last name, email, company name, address). The legal basis is your consent (Art. 6(1)(a) GDPR), given via checkbox; the timestamp is stored. Your IP address is stored solely as an irreversible SHA-256 hash for abuse prevention — never in plain text.

3. AI analysis

The text you enter in the demo is transmitted to the AI provider configured by you or us (Anthropic or OpenAI) to create the analysis. Do not enter any sensitive personal data.

4. Offer creation

If you request a personal offer, we use the master data you provided in the gate to create the offer PDF and send it by email.

5. Contact form

For a contact request we process name, email and message to handle your enquiry (Art. 6(1)(b)/(f) GDPR). Delivery is via SMTP.

6. Cookies & local storage

Only session and CSRF cookies are essential. Functional services (e.g. LinkedIn button, booking calendar) only load after your explicit consent. We store your cookie decision in your browser (localStorage).

7. Usage analytics (Umami)

We use Umami for statistical analysis of usage – a privacy-friendly analytics tool that we self-host on a server in Germany (Hetzner). No cookies are set and no cross-device profiles are created. The data collected (e.g. pages viewed, approximate origin, device type, anonymised interactions) is processed exclusively in aggregate and without a direct personal reference; IP addresses are not stored in plain text. No transfer to third parties or to third countries (in particular the USA) takes place. The legal basis is our legitimate interest in a needs-based design of our website (Art. 6 (1) (f) GDPR).

8. Your rights

You have the right at any time to access, rectification, erasure, restriction, data portability and objection. To delete your data, an email to the address above is sufficient.

9. Hosting & fonts

Fonts are served locally; no requests are made to Google servers. Hosting is on servers within the EU.
