This Privacy Policy explains how ZauStudios ("we", "us") collects, uses and protects information when you use the YDS & YÖKDİL mobile application (the "App"). By using the App you agree to this policy.

Depending on how you use the App, we may collect:
- Your name and email address, used to create and manage your account
- Study progress, answers, statistics, league and duel results (stored on our servers, linked to your account)
- Words you suggest, your votes and reports
- Your name, which is shown to other users in leagues and duels
- A notification token, used to send study reminders and duel notifications
- Usage statistics and crash reports, linked to your account ID
- Purchase and subscription status
02How we use information

We never sell your personal information and do not use it for any other purpose.

04Advertising
The free version of the App shows ads served by Google AdMob. To show and measure ads, AdMob may use your device's advertising identifier, IP address and information about how you interact with ads. In the EEA, the UK and Switzerland we ask for your consent before ads are personalised, and on iOS the App asks for permission before using the advertising identifier for tracking. If you decline, you may still see non-personalised ads.
- Android: Settings › Google › Ads lets you reset or delete your advertising ID.
- iOS: Settings › Privacy & Security › Tracking lets you turn off tracking for the App.
- Buying Premium removes ads from the App completely.
05Purchases
In-app purchases and subscriptions are processed by Apple (App Store) or Google (Google Play). We do not receive or store your payment card details.
06Your account and data deletion
You can delete your account and all associated data at any time by emailing supportzaustudios@gmail.com from the address linked to your account. We delete your data within 30 days of your request, except where we are legally required to keep it.
07Data retention and security
Data linked to your account is stored on our servers for as long as your account exists and is deleted when you delete your account.
Data stored on your device stays there and is removed when you uninstall the App. Information processed by third-party services is retained according to their policies. We use reasonable technical and organisational measures to protect information, but no method of transmission or storage is completely secure.
08Children's privacy
The App is not directed at children under 13 and we do not knowingly collect personal information from them. If you believe a child has given us personal information, contact us and we will delete it.
09Your rights
Depending on where you live (for example under the GDPR or the Turkish Personal Data Protection Law, KVKK), you may have the right to access, correct or delete your personal information, to restrict or object to its processing, and to complain to a data protection authority. To exercise these rights, contact us.
10Changes to this policy
We may update this Privacy Policy from time to time. Changes are posted on this page with a new "Last updated" date. Continued use of the App after changes means you accept the updated policy.
