Data Storage

BuildBrief stores all data locally in your browser using localStorage. This includes:

• Your API key
• API Base URL and model name
• Your product idea and clarifying question answers
• Generated SPEC.md and TASKS.md content
• Brief history (last 50 entries)
• Language and theme preferences

You can clear all locally stored data at any time by clearing your browser's localStorage for this site, or by using the "Change API key" / "Start Over" options within the app.

API Requests

When you generate clarifying questions, SPEC.md, or TASKS.md, your product idea, answers, and previous outputs are sent to BuildBrief's /api/ai route. This route forwards the request to the AI provider you configured (via your API Base URL and API Key). BuildBrief does not log, store, or retain these requests or responses on any server.

Third-Party Services

BuildBrief sends data only to the AI provider you configure. No data is sent to BuildBrief's operators or any other third party. Your API requests are processed by your chosen provider (e.g., OpenAI, DeepSeek) and are subject to that provider's privacy policy.

No Server-Side Database

The current MVP version of BuildBrief does not use any server-side database or persistent storage. All state lives in your browser's localStorage and is only retained as long as you choose to keep it.
