Help & Support
Having trouble, want to share your experience, or need help with your subscription? Contact Tolux at info@tolux.org. You do not need to sign in to ask for help.
Send a support request
This form prepares an email in your email app. You must send it there; nothing is submitted or stored by this page.
If your email app does not open, email info@tolux.org directly with your request.
Billing and cancellation
To request cancellation, choose “Cancel my subscription” above and include the email used to subscribe. Sending a request does not itself cancel the subscription. Ask for confirmation of the cancellation and its effective date. Signing out or stopping use of the app does not cancel billing.
Self-service subscription management is not available on this page yet. For billing problems or difficulty accessing a paid account, contact us using the same form.
Refund requests
Choose “Refund request,” include your account email, the charge date, and the reason for your request. Requests are reviewed individually; this page does not issue or guarantee a refund.
Report a math issue or share feedback
For a grading issue, include the lesson or test name, question, your answer, and the result shown. For feedback or a complaint, tell us what worked, what did not, and how we can improve.
