Terms of service

Last updated: November 7, 2026

By creating an account or using CellQuest you agree to these terms.

Your account

You need a valid email address to create an account. Keep access to your email secure, as it's how you sign in. One account is for one person.

Free and Premium

The Beginner course is free. Premium gives access to intermediate and advanced lessons, including new Premium lessons as they are released. Premium is a subscription billed monthly or yearly by our payment provider, Lemon Squeezy, and renews automatically until you cancel.

Cancelling

You can cancel anytime under “Manage billing” on your account page. You keep Premium until the end of the period you've paid for. Refunds are covered by our refund policy.

Acceptable use

Don't share your account, copy or resell the course content, or try to access parts of the service you haven't paid for.

Content

The lessons, exercises and design are owned by CellQuest. Microsoft Excel is a trademark of the Microsoft group of companies. CellQuest is not affiliated with or endorsed by Microsoft.

No guarantees

We work hard to make CellQuest accurate and available, but we provide it “as is” and can't guarantee it will be error-free or that it will lead to a particular job or result. To the extent the law allows, our liability is limited to the amount you paid us in the last 12 months.

Changes

We may update these terms. If a change is significant we'll let you know by email before it applies.
