By creating an account or using Underlayer, you agree to these Terms of Service. If you do not agree, do not use the platform.
You are responsible for keeping your account credentials secure and for all activity that occurs under your account. You must provide accurate information and be old enough to form a binding contract in your jurisdiction.
You agree not to misuse the service, including by attempting to disrupt it, accessing other users' data, scraping content at scale, or using the platform for unlawful purposes.
Course content is provided for educational purposes. We work to keep it accurate, but we make no warranty that it is free of errors. Technical content may change as specifications and tools evolve.
You retain ownership of notes and other content you create. You grant us the limited rights needed to store, process, and display that content back to you as part of the service.
The service is provided "as is" and "as available". We may modify, suspend, or discontinue features at any time. We are not liable for interruptions or data loss, though we take reasonable care to avoid them.
You may delete your account at any time. We may suspend accounts that violate these terms. On termination, your access ends and your data may be deleted in line with our Privacy Policy.
We may update these terms. Material changes will be reflected by updating the date above. Continued use after a change constitutes acceptance.
