Support & contact
A question, a bug, a GDPR request, or a B2B integration? Here is how to reach us.
Email us
Email is the fastest channel. Please include your browser (Chrome, Firefox…), the LLM platform (ChatGPT, Claude, Gemini…), and a short description of the issue or request.
✉ [email protected]Response time
We answer within 24-48 business hours on average (Mon-Fri, 9 am-6 pm CET). Security-related requests (suspected leak, vulnerability, exposed secret) are prioritised — start the subject line with 'SECURITY' for immediate escalation.
Frequently asked questions
- The extension doesn't detect my data — what should I do?
- First, make sure you are on one of the 7 supported platforms ( ChatGPT, Claude, Gemini, Qwen, DeepSeek, OpenRouter, Mistral Le Chat). Then hard-reload the tab (Cmd+Shift+R) and send a prompt containing a visible email address. If detection still doesn't fire, email us a screenshot of the DevTools console (right-click → Inspect → Console).
- False positive (data masked when it shouldn't be)
- The SafePrompt popup ships a "Report false positive" button next to each detection — it sends the minimal context (entity type, platform) without ever transmitting the original prompt. Otherwise, email us with the entity that was wrongly detected and the prompt you used.
- GDPR request (access, rectification, deletion, portability)
- Email [email protected] with subject "GDPR — <nature of the request>". We acknowledge within 72 hours and process within the legal one-month window. See also our Privacy Policy and Trust & Security page.
- B2B integration / Business plan / commercial questions
- Tell us briefly: target seat count, industry, specific requirements (anonymization mode, EU hosting). We offer personalised demos and Business plans (50+ seats) with priority support.
