Data Security

We implement industry-standard security measures to protect your data:

• All data is transmitted over HTTPS (TLS encryption).
• Passwords are hashed using bcrypt — we never store your plain-text password.
• Access to production data is restricted to authorized personnel only.
• JWT tokens with expiry are used for authentication — no sensitive credentials are stored in the app.

Despite our best efforts, no method of transmission over the internet is 100% secure. We encourage you to use a strong password and not share your account credentials.
