Privacy Policy

Last updated: June 9, 2026

Overview

BayesChat is a local AI chat client that connects to third-party AI providers configured by the user. We are committed to protecting your privacy.

Data Collection

BayesChat does not collect, store, or transmit any personal data to our servers. All data remains on your device.

API Keys

Your API keys for third-party AI providers (such as OpenAI, Anthropic, Google, etc.) are stored locally on your device using Apple's Keychain. They are never sent to us or any third party other than the AI provider you configure.

Conversations

All chat conversations are stored locally on your device using SwiftData. They are not backed up to or synchronized with any external server by BayesChat.

Third-Party AI Providers

When you use BayesChat to interact with AI providers, your messages are sent directly to the provider you have configured (e.g., OpenAI, Anthropic). Please review the privacy policy of each provider for their data handling practices.

Local Network Access

BayesChat may access your local network to connect to self-hosted AI servers (e.g., Ollama, LM Studio). This communication stays within your local network.

In-App Purchases

BayesChat offers a one-time “Pro” unlock purchase through Apple's App Store. Purchase verification is handled entirely by Apple's StoreKit. We do not have access to your payment information.

Analytics and Tracking

BayesChat does not use any analytics, tracking, or advertising SDKs.

Children's Privacy

BayesChat does not knowingly collect any information from children under the age of 13.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be reflected in the app and on this page.
