Privacy policy

Last updated November 13, 2026

Answer Check Pro ("we") is a Chrome extension that checks quiz answers with AI. This page explains what data it uses and why. We do not sell your data, show ads, or use trackers.

What we collect

• Google account basics. When you sign in with Google we receive your name, email address, profile picture and Google account ID. We use them to identify your account and plan.
• Quiz content you ask us to check. When you check a quiz, the extension sends the question text, answer choices and short excerpts from your course readings to our server. Our server sends them to Anthropic's Claude AI to get the check results, then returns the results to you. We do not keep the questions or readings after the check is done.
• Free-plan counting. For free accounts we store a one-way fingerprint (a hash) of each question checked, so the free plan can be limited. The fingerprint can't be turned back into the question.
• Usage counts. We store how many checks each account makes per day and how much AI processing they used, to prevent abuse and control costs.
• Payments. Payments are handled by Stripe. We never see or store your card number. We store your Stripe customer ID, your plan, and its status and renewal date.

What stays on your computer

Course readings the extension gathers, your check results, and your settings are saved in your own browser's extension storage. They are not sent to us except for the excerpts needed for a check, as described above.

Who we share data with

• Anthropic (Claude AI) processes quiz content to produce check results.
• Stripe processes payments.
• Google provides sign-in.
• Cloudflare hosts our server and database.

Each handles data under its own privacy terms. We share nothing else with anyone, except where required by law.

Permissions the extension uses

The extension reads quiz and course pages on Canvas and MyOpenMath so it can find the questions and your class readings. It does not read other websites' content unless you open course material hosted there from your class.

Keeping and deleting data

Account and payment records are kept while your account exists and as required for tax and accounting. You can ask us to delete your account at any time; uninstalling the extension removes everything stored in your browser. You can also remove Answer Check Pro's access at myaccount.google.com/permissions.

Children

Answer Check Pro is meant for students 13 and older and is not directed at younger children.

Changes and contact

If this policy changes we'll update the date above. For questions or deletion requests, email support@answercheckpro.com.
