How can we help?

Email tereteresupport@gmail.com for account access, payments, cancellation, refunds, or privacy requests.

Help us find the problem

Include your account email, what happened, and the page or feature involved. For billing, include the charge date and invoice reference if available. A screenshot can help, but remove sensitive information first. Never send passwords, verification codes, full card numbers, or security codes.

Manage your subscription

Go to Settings → Manage billing to view invoices, update payment details, or cancel renewal. See Cancellation and refunds for refund and withdrawal requests.

Account and privacy requests

For account deletion, access to server-held records, or a correction, use the support option associated with your account where possible. Say whether you also want to cancel a paid subscription. See Privacy for local learning data and your rights.

Learning data

Use Settings to export a backup of learning progress. It is stored on your device; support cannot restore browser data that has been cleared unless you have a backup.
