How we protect merchant data, cashier sessions, and customer loyalty records.
Cryptographically signed sessions separate merchant administrators, store staff, and platform operators with strict permission scopes.
Every customer queue, reward transaction, and stamp card is strictly scoped by merchant ID across all database queries.
All communication runs over TLS 1.3. Google OAuth refresh tokens and API credentials are stored encrypted at rest.
High-concurrency SQLite WAL mode prevents transaction locks during simultaneous peak-hour cashier check-ins.
