2. Technical delivery and server logs
Technically necessary data such as IP address, time, requested page, browser and operating system is processed for secure delivery based on Art. 6(1)(f) GDPR.
3. Repair requests and photo uploads
We store appliance details, problem description, language, selected region and the generated result. Photos are held privately, processed for analysis and deleted immediately afterwards, no later than 24 hours. Private results normally expire after 90 days.
4. AI processing by OpenAI
Appliance details, problem description and, where provided, the rating-plate photo are sent to the OpenAI API to generate the requested analysis. Do not enter or upload unnecessary personal data.
5. Public guides
Eligible results may be stored as public guides only after anonymization and without photos, email addresses or serial numbers. Public content is prepared from separate technical fields and provided in five languages. Unclear device identity requires further review; hazardous cases are limited to safe assessment, professional service and alternatives.
6. Advertising and consent management
Google AdSense, including Rewarded Ads or Offerwall, may be used for financing. Non-essential advertising and storage access only occurs after any required consent through a certified consent-management platform.
7. Email delivery
If you choose optional email delivery, the address is used only to send the requested result link and is not stored for newsletters or advertising.
8. Your rights
Subject to legal requirements, you have rights of access, rectification, erasure, restriction, portability and objection, plus the right to complain to a data-protection authority.
Quality feedback and search demand
This section was updated on 10 September 2026. You may voluntarily submit yes/no feedback and a predefined optional answer about a public repair guide. There is no free-text field or public rating. We use the information for editorial improvements and do not link it to private repair requests.
We reuse the existing fixnavi_session cookie to secure submissions and prevent repeated votes during the same session. It is a session cookie with Secure, HttpOnly and SameSite=Lax. We add no feedback or tracking cookie. The server session records only which public guide and revision received a vote, not the answer.
To prevent abuse, we briefly process the IP address received by the server. A secret key that changes daily produces a technical HMAC identifier; IPv6 addresses are grouped by /64 network. Feedback and demand tables contain no plaintext IP address or User-Agent. These identifiers are pseudonymous, not automatically anonymous. Signed submission proofs expire after 15 minutes. Daily guards expire at the next UTC day boundary; short counters and one-time proofs expire within two and 15 minutes respectively. Cleanup runs every minute. Normal retention is at most 24 hours plus up to one minute until cleanup.
Only daily totals by public guide, revision, language and selected answer are retained long term. Search demand counts only exactly approved public model or component terms, language and whether a qualified match was found. Other input is discarded for these statistics; no search text or hash of it is stored in the demand data. Repeats are limited. Counts are neither unique people nor verified successful repairs.
The legal basis for this limited quality analysis and abuse prevention is our legitimate interest in reliable repair information and a secure service, under Article 6(1)(f) GDPR. Necessary session access relies on section 25(2)(2) TDDDG. We create no user profiles, advertising IDs or links to photos and private analyses. You may object to legitimate-interest processing on grounds relating to your particular situation; contact details and further rights are provided in this notice.
Hosting access logs are separate. They may contain IP address, time, requested URL including search parameters, status, referrer and browser identifier. Current hosting rotation uses a 10 MiB size threshold and up to ten compressed archived files, with no fixed retention period in days. The short feedback-guard retention does not apply to these separate server logs.
