This Privacy Policy explains how StudyHub ("we", "us", or "our") collects, uses, and protects information when you use the StudyHub mobile application (the "App") on Android and iOS devices.
The App is intended for parents and legal guardians of children attending a study center ("StudyHub"). The App is not directed to children.
User accounts are created and managed by StudyHub. Parents/guardians receive their login credentials from StudyHub.
Data Controller: StudyHub
Address: Kerasountos 10, Aigaleo 122 42, Greece

The App may display information related to a child’s participation in StudyHub, as provided by StudyHub, such as:
To support offline mode and improve performance, the App stores data locally on your device. This cached data may include the information described above (including child-related information, reports, attendance, and schedules), as well as your preferences.
You are responsible for maintaining the security of your device (e.g., device passcode/biometrics). If you use a shared device, other device users may be able to access locally cached data.
The App uses push notifications to inform you about updates such as new progress reports or other Study Center notifications.
Push tokens are used only for delivering service notifications and are not used for advertising or cross-app tracking.
To improve stability and fix bugs, the App uses Firebase Crashlytics (Google LLC) for crash reporting. Crash reports may include diagnostic information such as:
We do not intend to send the content of your child’s records (e.g., reports/attendance) to Crashlytics. However, logs and diagnostics can sometimes include incidental technical data depending on the nature of the crash.
We use information strictly to:
User authentication is performed via a backend API over encrypted HTTPS connections. After a successful sign-in, the server issues a
JSON Web Token (JWT). The JWT contains only an internal user identifier (user_id) and is used to authenticate subsequent API requests.
When you log out, the App deletes the JWT from the device. We do not store JWTs in our database for lookup. Access is therefore limited by the token’s validity period and normal server-side authorization checks.
We process personal data under one or more of the following legal bases, as applicable:
StudyHub is responsible for ensuring that the necessary permissions/consents and declarations related to children’s data are collected from parents/guardians as required by law.
We share limited data with third-party service providers that help us operate the App:
These providers process data on our behalf as service providers, under their own privacy terms and security practices.
Relevant policies:
If you are in the European Economic Area (EEA), you may have rights including access, rectification, deletion, restriction, objection, and data portability, subject to applicable law.
To exercise your rights, contact us at info@studyhub.gr. We may need to verify your identity before fulfilling requests.
Because accounts are managed by StudyHub, certain requests (e.g., updating child-related records) may require coordination with StudyHub.
We implement reasonable administrative, technical, and organizational safeguards designed to protect information, including encrypted transport (HTTPS). No method of transmission or storage is completely secure.
Our service providers (e.g., Google Firebase, Apple) may process data on infrastructure located outside your country. Where applicable, transfers are handled under appropriate safeguards.
We may update this Privacy Policy from time to time. We will post the updated version on this page and update the "Last updated" date. Continued use of the App after changes become effective indicates acceptance of the updated policy.
