Marketing cookies (_fbp, _fbc) are only set after you explicitly consent. You can withdraw consent at any time using the cookie preferences button at the bottom of the page.
We use Vercel Analytics, which is a privacy-first analytics solution. It does not use cookies and does not collect any personally identifiable information. Data is aggregated and anonymized.
With your consent, we load the Meta Pixel — a script provided by Meta Platforms Ireland Ltd that sets the _fbp and _fbc cookies listed above.
When you complete a booking, we additionally use Meta's Conversions API — a server-to-server integration that sends conversion signals directly from our server to Meta. This allows us to measure whether our advertising campaigns lead to actual bookings, even when browser-based tracking is blocked.
Data sent via Conversions API includes: hashed email address, hashed name, IP address, browser user agent, and the _fbc/_fbp values (if available). Email and name are irreversibly hashed with SHA-256 before leaving our server. This data is used solely for ad measurement and is processed by Meta under their Data Policy.
When you book a call, the embedded Cal.com scheduler may set its own cookies. Please review Cal.com's Privacy Policy for details.
