Email support@circlevoice.aiDuring public beta, we aim to reply within two working days. Do not send passwords, API keys or full card details by email.Sign-in problems
Confirm that you are using https://circlevoice.ai, then retry in a private or incognito window. Email sign-in links can be used only once; request another if yours has expired. For Google sign-in failures, note the on-screen error and the time it occurred.
Voice problems
Check browser microphone permission, the selected input device and media volume. iPhone Safari may ask you to tap the circle again before playing an answer. With Bluetooth, confirm that the selected device includes a microphone.
Billing and cancellation
After signing in, select the account icon at the top right and choose “Manage billing / cancel renewal” to open the Stripe billing portal. Unless stated otherwise, you can normally use Plus until the end of the current period after cancelling, and it will not renew.
Chat history
After signing in, open “Chat history” from the account menu. Every chat is independent, and a new conversation never imports messages from another chat. You may permanently delete individual conversations from the list.
Permanently deleting an account
Choose “Delete account” in the top-right account menu and type DELETE to confirm. Circle first cancels the related Stripe subscription immediately, then permanently deletes the account and all saved conversations. If you only want to stop the next renewal and keep this period’s Plus access, cancel through the billing portal instead.
What to include in a report
- The date and Hong Kong time of the issue

- The state shown at the time, such as Listening, Thinking, Speaking or Error
- Steps that reproduce the problem and a screenshot with personal data hidden
- For payment issues, the Stripe receipt email or transaction date—but never the full card number
