Terms of Service

Account

You're responsible for keeping your account credentials secure. One account per person — please don't share logins. Pro subscriptions are for individual use; team plans are available separately.

Content

All concept guides, problem descriptions, and study materials on CalibreOS are copyrighted. You can use them for personal interview prep. You can't republish, resell, or redistribute them — including feeding them into competing training datasets.

Subscriptions

Pro plans bill monthly or annually and auto-renew until cancelled. Cancel anytime from your dashboard — you keep Pro access until the end of your billing period. Refunds are handled case-by-case; reach out if something went wrong.

Fair use

Don't scrape, abuse rate limits, or try to break the platform. Don't use CalibreOS to cheat in live interviews. We reserve the right to suspend accounts that violate these terms.

No guarantees

CalibreOS helps you prepare — it doesn't guarantee offers. The platform is provided "as is" without warranty of any kind.
