Terms of service
Draft, 14 November 2026 (to be reviewed before launch)
These terms are the agreement between you and Kothon for the AI phone agent service. By creating an account you accept them.
1. The service
Kothon lets you set up AI agents that answer and make phone calls in Bangla and English on your own phone lines, with a dashboard and an API. Features, voice qualities and prices may change; we will tell you about changes that affect you.
2. Your account
You must give correct details and keep your password safe. You are responsible for everything done through your account, including your team members and API keys.
3. Acceptable use
Use the service only for lawful calls. Do not use it for spam, harassment, fraud, impersonation, or to pressure people who have said no. Follow the telephone, privacy and consumer laws of the places you call, respect do-not-call requests, and make sure you have the right to call every number you upload. We may suspend an account that breaks these rules.
4. Calls with an AI
Callers should know they are speaking with an AI. The agent says so at the start unless you switch that off in the agent settings; you remain responsible for telling callers when a call is recorded where the law requires it.
5. Credit and charges
Calls are charged per minute of call time, in 6-second steps, at the price of the voice quality chosen for the agent, from your prepaid credit. New calls are refused when credit runs out. Prices are shown in your dashboard and may be changed with notice.
6. Your call data and how we use it
Transcripts, summaries, call details and recordings belong to you and are stored in your account. We use them to run the service. We use them to improve the service only if you switch on "Use my calls to improve the service" in Settings, with phone numbers hidden, and you can switch it off at any time. We never sell call data.
7. Availability and responsibility
We work to keep the service running, but calls depend on phone providers, networks and third-party speech and language services, and the AI can make mistakes. The service is provided as it is; to the extent the law allows, we are not liable for indirect losses, and our total liability is limited to the amount you paid in the last three months.
8. Ending the agreement
You can stop using the service and ask us to delete your account at any time. We may suspend or end accounts that break these terms. Unused credit is handled as set out when you buy it.
9. Changes and contact
We may update these terms and will post the new version here. Questions: use the contact page.
