Data Validation
- Input validation for subscription data
- Message size limits (100 chars)
- Notification type validation
- Consider adding input sanitization for messages
Database Security
- SQLite database with configurable path
- No raw SQL queries (uses SQLAlchemy ORM)
- Consider adding database connection pooling
- Consider encryption at rest for sensitive data
Push Notification Security
