Site measurement and your choice

Vercel Analytics provides cookieless aggregate page and click counts; account and order identifiers are removed from URLs before sending. We do not use advertising or retargeting cookies. Unless you have previously turned analytics off, PostHog starts automatically. PostHog measures the pages you visit, link and button interactions, and the time each page remains visible on screen. A random analytics identifier is stored in your device’s localStorage; your name and email address are not sent to PostHog. If you open a personal link sent on Instagram, its random reference code is stored in this browser for up to 30 days. Your teacher can associate visits from this link with the Instagram username it was sent to. The username is stored only in the teacher panel and is not sent to PostHog. Opening the link does not verify the visitor’s identity. Turning analytics off also clears this reference from your browser. About 20% of sessions on public information pages with analytics enabled are replayed with text masked; form fields, payment and sign-in pages, and student/teacher panel screens are excluded from replay. Data is sent to PostHog’s European Union region. You can turn analytics off or back on at any time using Privacy preferences in the website footer or the portal account menu. Turning analytics off applies on this device until you change your preference or clear browser storage; an on preference is stored for 180 days. Previous rejections are respected. Turning analytics off does not prevent you from using the service.

Third parties

The iyzico payment page you are redirected to for card payments may use its own strictly necessary cookies, governed by iyzico's policy.

When analytics is enabled, the random code in a personal introductory-meeting link sent on WhatsApp is included in form-open, step-completion and submission events. Your teacher can associate that code with the phone number the link was created for in the teacher panel. Your phone number, form answers and voice recording are not sent to PostHog; the form is not recorded. The link code is not saved in browser storage. You can turn analytics off using Privacy preferences at the bottom of the form. Submitting the form still associates the application with the invitation when analytics is off. Forwarding a link may associate another person’s application with that link; the link does not verify identity.
