Privacy notice: We process data that you voluntarily submit through forms, the customer portal or the support chat to handle your request, perform services, document work and protect the website technically. Necessary cookies and session data are used for login, CSRF protection, language preferences and site operation. Optional support-chat memory and privacy-friendly visit analytics are activated only with voluntary consent. Visit analytics record pages viewed, visible usage time, a coarse device, browser and operating-system class, a truncated IP address, monthly rotating pseudonymous identifiers and – only when supplied by a trusted hosting proxy – an approximate region. We do not use canvas, font or audio fingerprints, advertising profiles or third-party trackers. Analytics data are normally retained for no more than 90 days; withdrawing consent in Cookie settings stops collection and deletes analytics sessions linked to the consent identifier. You may request access, correction, deletion, restriction and objection. Do not send passwords, API keys or unnecessary personal data through free-text fields. In the protected customer project chat, the original message, translation, selected service/order context, reply drafts and delivery status are stored to handle and document the communication. Minimized excerpts are processed only server-side through the configured OpenAI API for translation and reply drafts; suggestions are never sent automatically. The customer selects the reply language and confirms the AI notice for each message; the notice version and acknowledgement time are recorded. Credential-like content is held before AI processing and remains stored locally for manual review. Project chats with no new activity and related notifications are removed regardless of status after the configured period (365 days by default) in bounded cleanup runs; the actual period and legal basis must be confirmed before live operation.
