Terms of Service
Last updated: October 22, 2026
These terms cover your use of Hidio (the website at hidio.app, the browser extension and related services). By creating an account or using Hidio you agree to them.
Your account
You sign in with an email address you control. You are responsible for activity on your account. You must be at least 13 years old to use Hidio.
Using Hidio
Hidio gives study help: answers and explanations for the questions you show it. You are responsible for how you use that help and for following the rules of your school, course and any test you take. Answers are generated automatically and can be wrong; check anything that matters.
Don't misuse the service: no reselling access, automated scraping, attempts to break or overload the service, or uploading content you have no right to share.
Plans and billing
Paid plans renew automatically every week or month at the price shown at checkout until you cancel. You can cancel any time from your account page; you keep access until the end of the period you have paid for. Payments are processed by Stripe. Unlimited plans are subject to a fair-use limit of 400 answers per day.
Refunds
See our refund policy.
Changes and termination
We may update Hidio and these terms. We may suspend accounts that break these terms. You can stop using Hidio and ask us to delete your account at any time.
Disclaimer
Hidio is provided "as is" without warranties of any kind. To the extent allowed by law, our total liability is limited to the amount you paid us in the 30 days before the claim.
