Privacy Policy
Last Updated: November 17, 2025
1. Introduction
BD1 LLC ("we," "our," or "us") operates BD1.ai ("BD1"), an AI-powered business development automation tool for Telegram. We are committed to protecting your privacy and being transparent about how we handle your data.
This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our service.
2. Our Privacy-First Architecture
Key Privacy Features:
- Client-Side Processing: Your Telegram data is processed locally in your browser and does not touch our servers
- Session-Less Architecture: We do not store your Telegram credentials or authentication tokens on our servers
- Browser-Only Storage: Telegram conversation data remains in your browser's local storage and is never uploaded to our backend
- You Control Your Data: You can disconnect and delete your data at any time
This architecture means that even if our servers were compromised, your Telegram data would remain secure because we never store it.
3. Information We Collect
3.1 Information You Provide
When you use BD1, we may collect:
- Account Information: Email address, name, and account preferences
- Telegram Connection: Authorization to access your Telegram data (processed client-side only)

3.2 Telegram Data (Client-Side Only)
When you connect your Telegram account, the following data is processed locally in your browser:
- Telegram messages and conversations
- Contact information from your Telegram contacts

Important: This data is stored only in your browser's local storage and is never sent to our servers unless you explicitly trigger an AI query or export action.

When you disconnect your Telegram account or clear your browser data, all locally stored Telegram information is permanently deleted.
6. AI and LLM Processing
BD1 uses artificial intelligence and large language models to process your queries. Here's how it works:
6.1 What We Send to AI Providers
When you make an AI query (e.g., "Summarize my unread messages"), we send:
- Your natural language query

6.2 Third-Party AI Providers
We currently use the following AI service providers:
- OpenAI (GPT models)
- Anthropic (Claude models)
- Other LLM providers as we expand our capabilities
These providers process your data according to their own privacy policies. We minimize the data sent and do not share unnecessary personal information.
6.3 AI Data Retention
We configure our AI providers to:
- Not use your data for training their models (where supported)
- Delete query data after processing (according to their retention policies)
- Maintain industry-standard security and encryption

Your Responsibility: You are responsible for ensuring you have proper authorization to sync Telegram data with third-party services and for complying with their terms of service and privacy policies.
