Privacy Policy

Last updated: November 10, 2026

This Privacy Policy explains how Fonoster Inc. ("Fonoster", "we", "us") collects, uses and shares personal data when you visit fonoster.com or fonoster.ai, or use Fonoster Cloud (the "Service"). It does not cover copies of the open-source Fonoster software you run yourself; we receive no data from those.

1. What we collect

Account data: your name, email address, workspace names, and the people you invite.
Billing data: your plan, credit balance and invoices. Card details are collected and stored by Stripe, not by us.
Customer content: what you put into or send through the Service: agent configurations, prompts, knowledge files, phone numbers, call audio, recordings, transcripts and call records (such as caller and callee numbers, times and durations).
Usage and technical data: logs, IP addresses, device and browser details, and how you use the dashboard and API.
Website analytics: fonoster.com uses Google Analytics, which sets cookies to measure visits.
Messages you send us: support requests and other emails.

2. How we use it

to provide, run and secure the Service, including routing calls and running the agents you configure;
to bill you and keep financial records;
to send you account and service emails, such as sign-in links, invitations and notices about changes;
to support you, fix problems and improve the Service;
to prevent fraud and abuse and to comply with the law.

We do not sell personal data, and we do not use your customer content to train AI models.

3. Customer content and your callers

For the people who call or are called by your agents, you are the controller of their personal data and we process it on your behalf, following your instructions and this policy. You are responsible for giving them any notice and getting any consent the law requires, for example before recording a call.

4. Who we share it with

Service providers that host and operate the Service for us, such as cloud hosting, email delivery, and payment processing (Stripe).
Providers you choose: carriers and speech-to-text, text-to-speech and language-model vendors you configure receive the call audio and text needed to do their job, under their own terms.
Legal reasons: when the law requires it, or to protect the rights and safety of Fonoster, our customers or others.
Business transfers: if Fonoster is involved in a merger, acquisition or sale of assets, subject to this policy.

5. How long we keep it

We keep account data while your account is active. Logs are kept for a limited period (30 days on the current plan). Recordings, transcripts and call records are kept until you delete them or your account ends. Billing records are kept as long as tax and accounting laws require.

6. Security

We protect data with access controls, encryption in transit and encryption of sensitive fields at rest. No system is perfectly secure; if a breach affects your personal data, we will notify you as the law requires.

7. International transfers

We and our providers may process data in the United States and other countries. Where the law requires it, we use appropriate safeguards for those transfers.

8. Your rights

Depending on where you live, you may have the right to access, correct, delete or export your personal data, to object to or restrict some uses, and to complain to a data-protection authority. You can update most account data in the dashboard. For anything else, email team@fonoster.com. If you are a caller of one of our customers, please contact that customer first; we will help them answer your request.

9. Children

The Service is not meant for children under 16, and we do not knowingly collect their personal data.

10. Changes to this policy

We may update this policy. We will post the new version here with a new date and, for material changes, notify you by email or in the dashboard.
