At Teacher-LM, we are committed to protecting the privacy of our users. This policy explains what information we collect, how we use it, and what rights you have regarding your personal information.

Sharing with Third Parties
We may share information only in the following cases:
- Infrastructure providers: cloud services providing technical infrastructure, bound by strict confidentiality agreements
- Legal requirement: when required by law to disclose information to authorities
Data Security
We take reasonable measures to protect your information from unauthorized access, alteration, disclosure, or destruction. However, no method of internet transmission is 100% secure, so we cannot guarantee absolute security.
Your Rights
You have the following rights regarding your information:
- Right of access: to know what information we hold about you
- Right to deletion: to request deletion of your personal information
- Right to restrict use: to request limitation on how your information is used

To exercise your rights, please use our [contact page](/en/contact).
Children's Privacy
The Service is intended for adult teachers and educators. We do not knowingly collect personal information directly from minor students. Homework content is processed as part of the service but is not linked to individual student identities.
Policy Changes
We may update this policy from time to time. Any material changes will be published on this page with advance notice. Continued use of the Service after changes constitutes agreement to the updated policy.
