Terms of service
Last updated 4 October 2026
Lectheo is a free prototype built for the ForgeHacks 2026 hackathon. By using it you agree to these terms.
The service
- Lectheo is provided “as is”, without warranty. It may change, break or be shut down at any time, and data may be lost.
- Questions, feedback and grades are generated and checked by AI. They are usually right, but they can be wrong. Lectheo is a study aid, not a substitute for your course materials or instructors.
- Daily usage limits apply to keep the service available for everyone.
Your responsibilities
- Only record or upload lectures you have permission to record or use, and follow your institution's rules.
- Don't upload content you don't have the right to share, and don't try to abuse, overload or break the service.
- Your study data stays yours. See the privacy policy.
