Common questions

01. Do I need another SIM card or phone number?

No. TonoCard connects to a compatible phone via Bluetooth. No extra SIM card or phone number is needed.

02. Can I use it with Bluetooth headphones or my car?

Yes. TonoCard can be used with Bluetooth headphones or your car's Bluetooth system.

03. What is the connection range?

Once connected, TonoCard can handle calls within a range of up to 5 meters from your phone.

04. What needs to stay on for AI to answer calls?

Keep your phone connected to the internet and Bluetooth, with the app running. It can run in the background. Enable notifications to use it while your phone is locked.

Closing the app disables all features. If Bluetooth or the internet connection is turned off, AI will no longer answer calls.

05. Can I hand a call back to AI after taking over?

No. Once you take over a call, you cannot hand that same call back to AI.

06. What if AI misjudges a call?

AI can make mistakes. Review the summary and original audio to decide whether to call back, then adjust your call rules if needed.

07. Will callers know it's AI? What if they don't want to talk to it?

The current demonstration opens with “Hello, I'm the AI secretary.” If a caller does not want to talk to AI, the phone owner decides how to handle it.

08. Will AI make important decisions for me?

No. AI prompts you to review the key points. The decision is yours.

09. Are calls recorded? Where are the records stored?

Summaries and original audio from the part of a call handled by AI are stored locally. You can review them in the app. Cloud data is used only for processing and deleted as soon as processing ends. Recording stops when you take over.

10. Could my cloned voice be stolen?

Before using voice cloning, you must read and accept the relevant privacy policy and terms of service. These appear when you first open the app and set up TonoCard. See the TonoCard Privacy Policy for details on how voice data is handled and protected.

11. How much are the plans? How many phones can I use?
