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. No advertising or third-party analytics have been added.
On your device
Theme, guest personal bests and recently seen questions are stored locally. Optional statistics keep up to 100 completed rounds and question IDs for reviewing mistakes on your device, separated by account or guest. They are not uploaded and are deleted when statistics are switched off. Without consent, mistakes remain only in session memory. Your active round, question order, answers and timer are saved in tab session storage to recover after a reload; leaving the round clears that temporary snapshot. If you sign in, session tokens and a separate account-specific personal-best cache are stored locally. Signing out does not erase guest records. Clearing app or browser data removes these local records.
Service providers
Google handles Google sign-in, 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 and cloud personal bests. 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.
