• User-generated content, such as vocabulary entries, lists, and notes created within the App;
• Technical information, including device type, operating system, app version, and language settings;
• Usage data related to interactions with App features;
• Push notification tokens required to deliver notifications.

2. How We Use Your Information

We use your information to:

• provide, operate, and maintain the App;
• authenticate users and manage user accounts;
• store and synchronize user data across devices;
• deliver push notifications related to App functionality;

3. Legal Basis for Processing (GDPR)

If you are located in the European Union, we process personal data based on one or more of the following legal bases:

• your consent;

• our legitimate interests, such as improving and securing the App.

4. Third-Party Services

We use trusted third-party services to operate the App, including:

• Supabase, for backend services, authentication, and data storage;
• Expo and Apple Push Notification service (APNs), to deliver push notifications;

These third-party services may process certain technical data or device identifiers solely for the purposes of providing their respective services and in accordance with their own privacy policies and applicable data protection laws.

5. Advertising and Consent

The App may display advertisements provided by third-party ad networks such as Google AdMob.

If you are located in the European Union, we will request your consent for personalized advertising in accordance with the General Data Protection Regulation (GDPR) using an approved consent mechanism. You may choose to receive non-personalized ads or withdraw your consent at any time via the App’s settings.

On iOS devices, the App may also request permission to track activity across apps and websites in accordance with Apple’s App Tracking Transparency (ATT) framework. Granting or denying this permission does not affect your ability to use the App.

We retain personal data only for as long as necessary to provide the App and fulfill the purposes described in this Privacy Policy, unless a longer retention period is required by law.

7. Account Deletion and Data Removal

You may delete your account and associated personal data at any time directly within the App. Upon deletion, your personal data will be permanently removed from our active systems, except where retention is required by law or for legitimate purposes such as security, fraud prevention, or backup integrity.
