Accounts are optional. You can take the quiz without registering. We do not ask for your age, phone number, address or payment details.
Account data
If you create an account, Supabase processes your email address, authentication records and password hash. Your password is not stored as readable text in this site's database. We keep your chosen nickname and standard-round personal best for each topic and difficulty, with update timestamps.
Sign in with Google
Google sign-in is optional. When you choose it and approve Google's permission screen, Google shares your email address, name, profile picture URL and account identifier, along with email verification information, with Supabase's authentication service. These basic profile details may be stored in your account's identity metadata. We use them to identify your account and let you sign in; your quiz nickname can be changed separately. We do not ask Google for access to Gmail messages, Drive files, contacts or YouTube data. Your Google password is entered only on Google's own sign-in screen, never on this site.
Google account data are not sold or used for advertising, marketing or AI model training. They are shared only with the services needed to authenticate and operate your account, or where legally required. This site does not use Google sign-in to access additional Google services in the background.
Purpose and services
These data are used to operate your account, send verification and recovery emails, protect access and sync personal bests between devices. Hetzner serves the website; Supabase provides authentication and cloud storage. Authentication emails use the configured email provider. These services may process connection and security logs. We do not use advertising trackers.
Website analytics cookies
Only if you choose Allow, we load Google Analytics 4 on the website to count visits and page views. Google may process your IP address, browser and device information, visited page path, and analytics cookie identifiers. We do not send your email, account ID, quiz answers or URL query parameters as analytics events. Google may process these data outside Türkiye. Analytics is separate from optional local quiz statistics and is not used in the Android app. Rejecting does not limit the quiz. We store only your Allow/Reject choice on this device so we can respect it on future visits.
You can change your choice with Cookie preferences on the website at any time. Withdrawing permission stops further Analytics tracking and removes accessible Analytics cookies from this browser; it cannot undo data already received by Google. For questions or deletion requests, contact the address above. Google's own retention and deletion rules also apply.
Analytics uses the first-party _ga and _ga_* cookies to distinguish visitors and sessions; Google documents a maximum cookie lifespan of two years. The local analytics-consent preference has no fixed expiry and remains until you change it or clear browser data. Analytics event-level retention is controlled separately in the Google Analytics property.
On your device
Theme, guest personal bests and recently seen questions are stored locally. With your optional statistics consent, up to 100 completed rounds and their question IDs, answer outcomes and completion times are kept on this device for statistics and the Knowledge Profile. Signed-in users also sync these round details to Supabase so their profile works across devices; guest records are never uploaded. Turning statistics off clears local history and deletes cloud Knowledge Profile rounds for the signed-in account. Without consent, mistakes remain only in session memory. Your active round is saved in temporary tab storage for reload recovery. Signing out does not erase guest records.
Service providers
Google handles optional Google sign-in and, with your separate permission, website analytics. Supabase handles account authentication and cloud records, Hetzner hosts the website, and Güzel Hosting sends account verification and recovery emails. Providers may process IP addresses, connection information and security logs as part of these services. Their infrastructure may process data outside your country.

Control and deletion
You can change your nickname, sign out or delete your account from My Account. Cloud account data remain until you delete the account. For access, correction or deletion requests, contact us below. Do not include your password. Data region, provider retention terms and the operator's legal privacy obligations must be confirmed before accounts are publicly launched.
Account Deletioninfo@yeninesilbilgiyarismasi.com
Account deletion removes the site's authentication account, stored Google identity metadata, nickname, cloud personal bests and cloud Knowledge Profile rounds. Provider backups and security logs follow the providers' applicable retention rules and may not be removed immediately. You can also revoke this app's access from your Google Account's third-party connections page; revoking access is separate from deleting the quiz account. Neither action deletes your Google account.
