Privacy Policy

Last updated: May 2026

Callio ("we", "our", or "us") respects your privacy. This Privacy Policy explains how we collect, use, share, and protect your personal information when you use our AI-powered phone assistant service. By using Callio, you consent to the practices described in this policy.

We process your data based on: (a) your consent, (b) performance of our contract with you, (c) our legitimate business interests, and (d) compliance with legal obligations.

1. Information We Collect

Account Information

Call Data

Payment Information

Device Information

Referral & Abuse Prevention

When you use an invite code, we record that you joined through it, linking your account to the friend who invited you. To keep free calls and invite rewards fair, we also use a pseudonymous identifier from your Google or Apple sign-in, an approximate network region (never your full IP address), and a device identifier — solely to stop the same person or device from claiming a bonus more than once. These signals are used only for abuse prevention — never advertising or profiling. To keep this protection working, one-way-hashed versions of your sign-in and device identifiers are kept after you delete your account — only as long as needed to prevent repeat bonus claims — and carry no other personal information.

2. How We Use Your Information

3. Call Recording & AI Disclosure

Important information about how calls work:

4. Third-Party Services

We use trusted third-party services to provide our functionality. Your data may be processed in the United States and other countries where our service providers operate:

Retell AI

Apple

AI Model Providers

We may use AI model providers, such as Google Gemini and OpenAI, to analyze call instructions, call context, transcripts, and related information to generate call plans, summaries, and responses. These providers process data on our behalf according to their applicable data processing terms and do not use your data to train their general-purpose foundation models. Providers may process limited data for abuse detection and safety as described in their terms.

Google Places

Provides business search and information. Your searches are not personally identified.
