Analytics and Tracking
We do not set or allow:
- Advertising or marketing cookies
- Social media tracking pixels
- Third-party advertising or tracking cookies
Sentry error and performance monitoring is opt-in. It starts only after you accept analytics in the consent banner and helps us diagnose crashes and performance issues.
Your Choices
- Clear the session cookie at any time to sign out
- Consent banner — accept or decline Sentry analytics when the banner is shown
- Delete your account from the Account page to permanently remove all data
- Browser settings — block or delete cookies (will prevent dashboard login)
Legal Basis
The session cookie is strictly necessary for the service you requested (dashboard access). Under GDPR Art. 6(1)(b) and ePrivacy Directive Art. 5(3), strictly necessary cookies do not require consent.
