Privacy Policy
Last updated: 2026-09-02
This Privacy Policy explains what information Bro Coach ("we", "us", "our") collects, how we use it — including how your data is processed by the AI models that power your coach — and the choices available to you.
1. Information We Collect
Account information: email address and authentication details, handled via our identity provider.
Chat messages: the messages you send to a coach and the replies you receive are stored so your conversation history persists across sessions.
Facts we learn about you: to make coaching feel continuous, we automatically extract durable facts from your conversations (for example, goals, routines, or preferences you mention) and store them for future context. You can also provide facts directly. See "Fact memory" below for how this works and how updates are handled.
Coach knowledge base content: if you or a coach creator submit websites, PDFs, or text to build a coach's knowledge base, that content is stored and used to answer related questions.
Avatar images: profile pictures you upload are stored in our file storage.
Payment information: purchases are processed by Apple (iOS In-App Purchase) or Stripe (web). We do not store your full payment card details ourselves.
Usage data: basic technical data needed to operate the Service (e.g., timestamps, token usage per request) for billing and reliability purposes.
2. How We Use AI to Power Your Coach
When you send a message, we assemble a prompt that may include:
Your current message and recent conversation history (up to the last 20 messages).
Relevant facts we've previously learned about you, so the coach can reference context from earlier conversations.
Relevant chunks from that coach's knowledge base, if one exists.
The coach's persona instructions (written by the coach's creator or our team).
This prompt is sent to a third-party large language model provider to generate the coach's reply. Depending on which model is configured for a given coach, this may be OpenAI, Anthropic, Google, OpenRouter, or Groq. These providers process your message content solely to generate a response; we configure these integrations to avoid using your data to train the providers' general-purpose models, but you should review each provider's own policy for details, as terms can change.
We also make a separate, automatic call to a language model after each message specifically to extract new facts worth remembering (see below), and — where enabled for a coach — a lightweight call to decide whether a reaction image should accompany the reply.
3. Fact Memory
To avoid making you repeat yourself, we extract structured facts from your messages (such as a goal you mentioned or a preference you stated) and store them with a category, confidence score, and the message they came from. When a fact changes, we record the update as a new entry rather than silently overwriting the old one, so context isn't lost mid-conversation — older superseded values are not currently deleted automatically. If you want a specific fact permanently removed, contact us (see "Your Choices" below) and we will delete it on request.
4. Coach Knowledge Base (RAG)
Coach creators can add a coach's knowledge base by submitting a website URL, a PDF, or raw text. Website and PDF content is fetched and parsed through a third-party content-extraction service, then broken into searchable chunks stored on our servers. When you chat with that coach, relevant chunks are retrieved and included in the prompt sent to the AI model to ground its answer.
5. Other Service Providers
Authentication and database: your account, messages, and facts are stored with our backend infrastructure provider.
File storage: avatar images and similar uploads are stored with our object storage provider.
Payments: Apple (iOS subscriptions/IAP) and Stripe (web payments) process purchases under their own privacy policies.
We do not sell your personal information.
6. Data Retention
We retain your account data, chat history, and extracted facts for as long as your account is active, so your coach relationship stays continuous. We do not currently have an automated retention limit that purges old data on a fixed schedule.
7. Your Choices
Self-service account deletion and data export are not available in the app yet. Until they are, you can request access to, correction of, or deletion of your personal data — including your account, chat history, and specific facts — by emailing bro@brocoach.win. We will verify your request and act on it as promptly as we reasonably can.
8. Children's Privacy
The Service is not directed to children under 13 (or the relevant minimum age in your jurisdiction), and we do not knowingly collect personal information from them.
9. Security
We use reasonable technical and organizational measures to protect your information, including encrypted storage of sensitive credentials such as third-party API keys. No method of transmission or storage is perfectly secure, and we cannot guarantee absolute security.
10. Changes to This Policy
We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Last updated" date above.
