5. Automated Decision-Making and AI Processing
The AI audit uses automated analysis of your responses via the Claude language model (Anthropic). Based on your business description and (optionally) analysis of your publicly available website, the AI generates personalized recommendations. The results are indicative and do not constitute binding advice. They have no legal effects and do not significantly affect you within the meaning of Art. 22 GDPR.
Safeguards: Before sending data to the AI model, personal identifiers (emails, phone numbers, addresses) are automatically removed. Anthropic does not use commercial API data to train its models. You have the right to request human review of the results — contact us at info@allier.studio.
6. How Long We Retain Data
We retain personal data only for as long as necessary for the given purpose:
- Contact form: up to 3 years from last contact
- AI audit (inquiries): for the duration of the business relationship, then up to 3 years; deleted upon request at any time
- Offers: for the validity period of the offer and then up to 3 years; anonymized upon request

After the retention period expires, data is permanently deleted or anonymized (name replaced with "[deleted]", email replaced with "anonymized@deleted.invalid", IP address and other identifiers removed). Anonymized data cannot be traced back to a specific individual.

8. Cookies and Analytics
This website does not use any marketing or analytics cookies. For traffic measurement we use self-hosted Plausible Analytics, which does not collect personal data, does not store cookies, and is fully GDPR compliant. No cookie banner is therefore required.
The administration interface uses a single technical HTTP-only cookie (admin_session) for administrator authentication. This cookie is strictly necessary for the operation of the admin area (Art. 5(3) ePrivacy Directive) and expires after 24 hours. Regular website visitors do not encounter this cookie.
9. Security
We use appropriate technical and organizational measures to protect your data: encrypted transmission (HTTPS/TLS), server-side input validation (zod schemas), form rate limiting, honeypot bot protection, timing-safe authentication token comparison, security HTTP headers (X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy), and serverless function hosting in the EU region (Frankfurt). Admin access is protected by HMAC-based session authentication with login attempt limiting.
10. Children's Data Protection
Our services are not intended for persons under 16 years of age. We do not knowingly collect personal data from children. If you become aware that a child has provided us with personal data, please contact us at info@allier.studio and we will delete the data promptly.
11. Changes to This Policy
We may update this policy from time to time, particularly when changing processors, processing purposes, or in response to changes in legislation. The current version is always available on this page with the date of the last update. In case of a material change, we will inform you by email (if we have your email) or by a prominent notice on the website.
