AI 2nd Line Privacy Policy

Effective July 20, 2026

AI 2nd Line ("the app") is an AI-powered second phone line by EString Software Corporation. This policy explains what we collect and why. Short version: we collect what the product needs to run your second line, we don't sell it, and we don't use it for advertising or tracking.

What we collect

• Account: your email address and a password (stored hashed).
• Phone numbers: your AI 2nd Line number(s) and, if you provide it, your personal phone number (used to recognize you when you call your own line).
• Calls: call metadata (numbers, times, duration), transcripts of calls answered by your AI receptionist, and audio recordings of voicemails and calls you choose to record. The AI discloses that calls may be recorded; you can turn this recording off in the app.
• Messages: texts sent and received on your AI 2nd Line number(s).
• Contacts: if you enable contact sync, names and numbers from your address book, used to show who's calling/texting and to let your assistant reach people by name.
• Usage: AI talk-time minutes, for plan metering.

How it's used

Solely to provide the product: routing calls and texts, screening calls with your AI assistant, transcription, notifications, and billing. We do not sell your data, do not use it for advertising, and do not track you across other apps or websites.

AI processing & third-party AI services

To power your assistant, the app sends your data to third-party AI services. Specifically:

• Call audio and transcripts are sent to Deepgram (speech-to-text) and to Anthropic (the Claude model, which generates your assistant's spoken and written replies).
• Message text you send or receive through the app is sent to Anthropic (Claude) when the assistant helps with a text.

This data is sent solely to operate your assistant — to transcribe, screen, and respond to calls and messages. It is never sold or used for advertising. Both Deepgram and Anthropic are bound by contract to protect this data with the same or equal protection described in this policy, to use it only to provide their service to us, and not to train their models on it. You are asked to consent to this AI data sharing inside the app before your assistant is used.

Other service providers

We also use: Twilio (telephony and SMS), ElevenLabs (text-to-speech), Apple (subscriptions), and Railway (hosting). Each receives only what's needed for its function and is contractually required to protect your data.

Retention & deletion

Your data is retained while your account is active. To delete your account and its data, use the contact form and we'll remove it within 30 days. Releasing a phone number deletes our routing for it immediately.

Call recording & consent

Recording laws vary by state. AI 2nd Line's receptionist announces that calls may be recorded by default. You are responsible for using recording lawfully in your jurisdiction.

Changes

We'll update this page when the policy changes; material changes will be noted in the app.
