Cookie Policy
Last updated May 18, 2026
This Cookie Policy explains how Furkan Sönmez ("Company," "we," "us," and "our") uses cookies and similar technologies to recognize you when you visit our website at https://furkan.sonmez.me("Website"). It explains what these technologies are and why we use them, as well as your rights to control our use of them.
What are cookies?
Cookies are small data files that are placed on your computer or mobile device when you visit a website. Cookies are widely used by website owners in order to make their websites work, or to work more efficiently, as well as to provide reporting information.
Cookies set by the website owner (in this case, Furkan Sönmez) are called "first-party cookies." Cookies set by parties other than the website owner are called "third-party cookies."
Why do we use cookies?
We use a small number of cookies that are strictly necessary for our Website to function. These cookies let you sign in, keep you signed in across pages, and protect against cross-site request forgery on authentication endpoints.
We do not use cookies for advertising, retargeting, cross-site tracking, or behavioral profiling. We do not embed third-party social media widgets, ad networks, or tracking pixels. We do not use Google Analytics or any cookie-based analytics service.
For website analytics, we use Plausible, a privacy-friendly, cookieless analytics tool that does not set cookies, does not collect personal data, and does not track visitors across websites.
Cookies we set
The cookies listed below are first-party, strictly necessary cookies. Because they are required for core site functionality (signing you in and keeping your session secure), they cannot be disabled through a consent banner; you can only block them via your browser settings, in which case sign-in will not work.
| Cookie | Purpose | Duration | Type |
|---|---|---|---|
authjs.session-token__Secure-authjs.session-token | Stores your authenticated session so you stay signed in across pages. The __Secure- variant is the HTTPS-only version used in production. | 30 days | Strictly necessary |
authjs.csrf-token__Host-authjs.csrf-token | Protects authentication forms against cross-site request forgery (CSRF) attacks. | Session | Strictly necessary |
authjs.callback-url__Secure-authjs.callback-url | Remembers the page you wanted to visit before signing in, so we can return you there after authentication. | Session | Strictly necessary |
authjs.pkce.code_verifier | Short-lived PKCE verifier used during the OAuth handshake with Google or GitHub. Set only while a sign-in is in progress. | Session | Strictly necessary |
We may also receive standard infrastructure cookies set by our hosting and CDN providers (Vercel, Cloudflare, Bunny.net) for security, load balancing, and bot mitigation. These are set automatically by the hosting platforms and contain no personal data.
How can I control cookies on my browser?
You can set or amend your web browser controls to accept or refuse cookies. If you choose to reject cookies, you may still browse public pages of our Website, but you will not be able to sign in or purchase course access. As the means by which you can refuse cookies through your web browser controls vary from browser to browser, you should visit your browser's help menu for more information:
How often will you update this Cookie Policy?
We may update this Cookie Policy from time to time in order to reflect, for example, changes to the cookies we use or for other operational, legal, or regulatory reasons. Please revisit this Cookie Policy regularly to stay informed about our use of cookies. The date at the top of this Cookie Policy indicates when it was last updated.
Where can I get further information?
If you have any questions about our use of cookies or other technologies, please email us at support@furkan.sonmez.me. For more information about how we handle personal data generally, see our Privacy Policy.
