Privacy Policy – StudyPacket

Last updated: April 2026

StudyPacket (“the App”) is developed and operated by AstralQuill, an independent developer. This Privacy Policy explains how information is handled when you use the App.

1. Account System

StudyPacket does not require user registration, login, passwords, or a traditional account system.

Some premium features, including cloud backup, may use Google/Firebase-generated identifiers and optional email-based identifiers solely for backup, restore, and service functionality.

2. Information We Collect

2.1 Device and Usage Data

• Device model and manufacturer
• Android OS version
• App version
• Language and region settings
• App interaction events (screen views, feature usage)
• Performance metrics (load time, responsiveness)

2.2 Crash and Diagnostics Data

Crash and error logs are collected to improve stability, including stack traces, device state at time of crash, and application version information.

2.3 Analytics Data

We use analytics to understand feature usage, session duration, and navigation flows. This data is aggregated and not used to identify individual users.

2.4 Push Notifications

We use Firebase Cloud Messaging to deliver notifications. This involves device push tokens and notification delivery data (sent, received, opened).

2.5 Cloud Backup (Premium Users)

Premium users may store app-generated data such as study content, settings, and backup metadata in cloud storage. This data is linked to a device or service identifier for restoration purposes.

5. Data Sharing

We do not sell personal data. Data is processed through Google Firebase infrastructure to enable app functionality.

6. Data Retention

Data is retained only as long as required to provide services, support backups, and meet legal obligations. Users may request deletion at any time.

7. Security

We implement reasonable technical safeguards to protect data against unauthorized access, loss, or misuse.

8. Children’s Privacy

StudyPacket is not intended for children under 13, and we do not knowingly collect personal data from children.
