Privacy Policy
Effective Date: September 2026 | Last Updated: September 24, 2026
1. Introduction & Scope
Welcome to HeyCall AI ("we", "our", "us", or "HeyCall"), provided by Rinvo Inc.. We are committed to protecting the privacy, security, and confidentiality of our users. This Privacy Policy describes how we collect, store, process, and safeguard your personal information when you access or use the HeyCall mobile application, our website (https://heycall.rinvo.in), our conversational AI voice receptionist, and related services.
By downloading, installing, registering, or using HeyCall AI, you explicitly consent to the collection, transfer, storage, and processing of information as explained in this policy.
2. Information We Collect
A. Account & Profile Information: When you register, we collect your verified phone number (via Firebase Phone Authentication), device identifier, preferred display language, and optional profile name.
B. Telephony & Call Information: When conditional call forwarding redirects calls to your dedicated HeyCall AI phone number, we process caller telephone numbers, call timestamps, durations, and routing metadata.
C. Audio Recordings & Transcripts: To provide real-time call handling, conversational AI responses, and post-call summaries, audio streams from callers and assistant speech are recorded, transcribed into text, and stored securely in your private account inbox.
D. Business & Knowledge Base Data: When you use our Business Hub, you may upload menus (PDF), price sheets (.xlsx, .csv), or submit website URLs. We process and extract text from these documents to train your AI receptionist's RAG memory.
3. How We Use Your Information
We use the collected information solely for legitimate service purposes, including:
- Answering forwarded incoming calls and holding contextual voice conversations with callers in natural Bengali, Hindi, or English.
- Accurately transcribing phone dialogues and extracting customer orders (items, delivery addresses) or appointment booking requests.
- Sending instant push notifications and alerts when new orders or calls are received.
- Allowing you to listen to full call audio recordings and read transcript summaries inside the app.
- Filtering unsolicited commercial telemarketing calls, spam, and fraud robocalls.
4. Third-Party Service Providers & Subprocessors
To deliver advanced conversational voice intelligence, we partner with industry-leading cloud infrastructure providers:
- ElevenLabs: Powers voice synthesis, speech recognition, real-time audio streaming, and RAG knowledge base search.
- Firebase (Google Cloud): Secures user phone authentication and push notification delivery.
- Telephony Carriers: Carrier-grade SIP routing and DID provisioning for incoming call forwarding.
We do not sell, monetize, or rent your personal information, call recordings, or transcripts to advertising agencies or data brokers.
5. Data Security & Storage
All API communications between the HeyCall app, our servers, and third-party AI engines are protected with industry-standard TLS 1.3 encryption. Call data and knowledge documents are stored in password-protected MySQL databases with strict access controls.
6. User Control & Data Deletion
You have complete ownership and control over your data. Inside the HeyCall app, you can delete individual call recordings, wipe call history, or delete uploaded knowledge base documents at any time with immediate effect on our servers.
