Current use
On an ordinary page visit the site sets no cookie of its own. No analytics, advertising or behavioural-targeting cookie is used, and no tool for those purposes runs on the site.
Technical cookies are written only when you use the related feature: requesting a resource by email, signing in to a Learn account, resetting your password or using the cart. Each one is listed below with its name, purpose and lifetime.
Tab storage
Apart from cookies, the site uses only the browser's tab storage (sessionStorage). Nothing kept there is sent to the server by itself, and it is cleared when you close the tab. Persistent local storage (localStorage) is not used.
Contact form: what you type is kept there so it is not lost when you switch language. Hidden fields are not stored, and the entry is removed once your enquiry is received.
Expandable sections: when you switch language, a short list keeps the sections you had open so they open on the other language's page too. The new page reads it once and removes it.
When the Learn checkout step is active, the visible fields of the checkout form are kept there for the same reason.
Resource-access cookie
gc_site_access is a first-party technical cookie written after you enter your email address, or after newsletter confirmation, so that you can access the resource you requested. It carries a signed representation of the resource identifier and, after confirmation, the subscriber identifier; it is HttpOnly and SameSite=Lax, and it is sent only on that resource's address. It lasts 24 hours.
Learn account, recovery and cart cookies
gc_learn_auth_v2 keeps you signed in to your Learn account; sign-in is provided by Supabase. It is HttpOnly and SameSite=Lax, and it is sent on every address of the site. If the session data is long, it may be written in numbered parts (gc_learn_auth_v2.0, gc_learn_auth_v2.1); during account verification or a password reset, short-lived helper cookies with the same prefix may also be written. The cookie is kept for up to 400 days and removed when you sign out; how long the session itself stays valid depends on the sign-in provider's settings.
gc_learn_login_email keeps the email address you typed after a failed sign-in, so you don't have to fill in the field again. It is HttpOnly and SameSite=Lax, lasts two minutes and is removed after a successful sign-in.
gc_learn_recovery_v2 supplies an additional authorisation check after you return from a password-recovery link. It is HttpOnly and SameSite=Lax, and lasts 10 minutes.
gc_learn_cart_v2 carries a signed cart identifier when the Learn cart is used; products, quantities and prices are not stored in the cookie. It is HttpOnly and SameSite=Lax, and lasts 30 days.
Management panel cookie
gc_management_auth_v1 is written only when I sign in to the site's management panel (/yonetim), and only for that address. It is not used in any visitor flow. It is HttpOnly and SameSite=Lax, is kept for up to 400 days and is removed when I sign out.
Cloudflare, Google Maps and third-party storage
The site runs behind Cloudflare's security layer. When Cloudflare needs to check a request for automated traffic, it may set its own technical cookie; Cloudflare determines that cookie's name and lifetime.
The map on the contact page is the site's own drawing; it does not load from Google, and no request is sent to Google when the page opens. The map therefore uses no Google cookies or similar storage.
If you follow the page's "Open in Google Maps" link, Google Maps opens in a new tab. Google may use its own cookies or similar storage in that tab; Google determines their names, purposes and lifetimes. Appointments are also not embedded; no scheduling cookie is written until you open the external Google link.
Choice and consent approach
If non-essential analytics, advertising or similar technology is added, it requires a clear preference screen before activation. Accept, reject and detailed settings must be equally accessible, with no pre-selected consent.
The contact page loads nothing from Google automatically. The "Open in Google Maps" link opens a new tab only when you follow it; a cookie preference on this site does not control that tab, and Google's own privacy and storage rules apply there.
Managing storage
You can view, remove or block cookies and site data in your browser settings. Blocking technical cookies may stop a feature you request, such as a session, cart, password recovery or resource access, from working.
