Privacy Policy

ZAVoiceAI ("we", "us", "ZAVoiceAI") provides an AI call-screening service for Android, built by BuySave. This policy explains what we collect through the app, why, and how it's protected. It applies to the ZAVoiceAI Android app and to this website.

What we collect

• Account information. When you sign in with Google, we receive your name, email address, and Google account identifier to create and secure your account.
• Phone numbers you configure. Your screening line, your trusted-numbers list, and any transfer number you set. These are used only to route and screen calls on your account.
• Call metadata. The number that called, the time, and the outcome (screened, transferred, or connected).
• Call transcripts. When a call is screened, the spoken conversation between the caller and the AI receptionist is transcribed and stored so you can read it. We only keep the final transcript of each turn — not intermediate speech fragments.
• Custom greeting text. Whatever you write for your AI receptionist to say.
• Subscription and billing status. Handled through Google Play Billing. We receive purchase and entitlement status from Google to unlock paid features — we do not receive or store your card details.
• Device push token. Used to notify your device when a screened call ends.

What we don't collect

• We do not access your phone's contact list, SMS messages, or call history outside of calls routed through ZAVoiceAI.
• We do not sell your data, transcripts, or phone numbers to anyone, for any purpose.
• We do not use your call transcripts to train third-party AI models.

How your data is isolated

Every customer's call data — settings, trusted numbers, greetings, and transcripts — is stored in an isolated, per-account instance on our infrastructure. Your data is never visible to, or mixed with, another customer's account.

How we use your data

• To answer, screen, and route your calls as you've configured.
• To show you call transcripts and history inside the app.
• To verify and maintain your subscription through Google Play.
• To operate, secure, and improve the reliability of the service.

Who we share data with

We use a small number of infrastructure providers to run the service, each processing data strictly on our behalf:

• Twilio — carries and transcribes the phone call itself.
• Cloudflare — hosts our backend and stores account data securely.
• Google — provides sign-in and subscription billing.

We do not share your data with advertisers or data brokers.

Data retention

Call transcripts and history are retained for as long as your account is active, so you can refer back to them. You can request deletion of your account and associated data at any time by contacting us below.

Your rights

You can request a copy of your data, ask us to correct it, or ask us to delete your account and all associated data. Email hello@zavoiceai.online and we'll action it within a reasonable time.

Children

ZAVoiceAI is not directed at children and we do not knowingly collect data from anyone under 16.

Changes to this policy

If this policy changes materially, we'll update the date at the top of this page and, where required, notify you in the app.
