We do not sell your personal information. We may share your information in the following circumstances:

Educators and classrooms

If you join a classroom, certain information is shared with the educator:

LMS integrations

If a teacher connects a classroom to Google Classroom or Microsoft Teams, assignment data and roster information may be synced between RevisionSuccess and the connected platform. This only occurs when a teacher explicitly connects the integration.

Legal requirements

We may disclose your information if required by law or in response to valid legal requests, such as subpoenas or court orders.

Business transfers

In the event of a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction. We will notify you of any such change.

We implement appropriate technical and organizational measures to protect your personal information, including:

• Encryption of data in transit (TLS) and encryption of sensitive credentials at rest
• Secure authentication with password hashing and OAuth token encryption
• Access controls and role-based permissions
• Regular security assessments

No method of transmission over the Internet or electronic storage is 100% secure. While we strive to protect your information, we cannot guarantee its absolute security. If you believe your account has been compromised, please contact us immediately.

We retain your personal information for as long as your account is active or as needed to provide you with the Service. We may also retain certain information as necessary to comply with legal obligations, resolve disputes, and enforce our agreements.

You can delete your account at any time through your account settings. When you request deletion:

• Your account is immediately deactivated and you are logged out
• Any active subscription is cancelled
• You have 14 days to cancel the deletion by logging back in
