Your choices
We do not load any non-essential analytics or diagnostics until you accept them. You can change your decision at any time:
Strictly necessary (always on)
Authentication session — an HTTP-only session cookie that keeps you signed in. The site cannot function without it, so it does not require consent.
Consent preference— your cookie choice is stored in your browser's local storage so we don't ask again on every visit.
Analytics & diagnostics (require consent)
These run only after you click Accept. They are cookieless but still process limited technical data, so we ask first.
Vercel Analytics — privacy-friendly, aggregate page-view and navigation measurement. No cross-site tracking.
Vercel Speed Insights — anonymous performance metrics (Core Web Vitals).
Sentry (browser) — captures JavaScript errors so we can fix bugs. Error monitoring on our servers runs independently of this choice. When an error happens it may record a replay of that session; form fields and text are masked.
PostHog — product analytics: which pages and buttons are used, so we can see where people get stuck. Sets cookies. Hosted in the EU. Records clicks on links, buttons and form submissions — never what you type into a field.
