This site sets no advertising, profiling or analytics cookies. There is no Google Analytics, no tracking pixel and no measurement tool of any kind installed. That is also why you see no cookie consent banner: only the technical data strictly necessary to run the service is used.
Cookies and browser storage we use
| Name | Type | Purpose | Lifetime |
|---|---|---|---|
| celsus-lang | Local storage (localStorage) | Remembers the language you chose (English/Turkish) | Stays in your browser until you clear it |
| celsus_pay_… | Strictly necessary cookie (HttpOnly, Secure, SameSite=Lax) | Binds the return from Stripe to the right agreement after payment; scoped to the /agreement/ path only | Short-lived; expires once the payment flow ends |
The language preference stays in your browser and is never sent to our server. The payment cookie is HttpOnly, so no script on the page can read it.
Third-party resources
When a page loads, your browser fetches fonts from Google Fonts (fonts.googleapis.com, fonts.gstatic.com) and interface libraries from jsDelivr (cdn.jsdelivr.net). Those requests disclose your IP address to the provider concerned. During payment you are taken to Stripe’s own domain, where Stripe’s cookies apply.
Server logs
Separately from cookies, our web server records requests (IP address, user agent, requested URL) for security purposes. Those logs are deleted automatically after at most 14 days.
Managing cookies
You can clear or block cookies and local storage in your browser settings. If the language preference is cleared the site reverts to its default language; if the payment cookie is blocked, the return step after payment may not complete. See the Privacy Policy for more detail.
