• No ads. We will never show advertisements to users.
• No third-party data sharing. We do not sell or share any data with third parties.

COPPA Compliance

Numra is designed to comply with the Children's Online Privacy Protection Act (COPPA). Our tools can be used without creating an account or providing any personal information. Teachers may create accounts to manage classroom settings, but student use requires no login or identification.

What We Store

• Local preferences: Tool settings (e.g., color choices, grid sizes) are stored in your browser's local storage and never sent to our servers.
• Essential cookies: If you log in, we use a session cookie solely for authentication. No tracking cookies are used.

Data Security

All data transmitted to and from Numra is encrypted using HTTPS/TLS. Teacher account passwords are hashed and never stored in plain text.

Data Deletion

Teachers can delete their account and all associated data at any time from their account settings. Local storage data can be cleared through your browser settings.
