Privacy Policy

Last updated: April 27, 2026

Brain Dump is a Pebble smartwatch app built by Adrien Thiery. This policy explains what data the app accesses, where it goes, and what is never collected.

What data the app processes

Brain Dump processes the voice notes you dictate on your Pebble watch. Depending on the destinations you configure in settings, a note may be sent to:

• Google Tasks — to create a task in your Google account
• Notion — to create a page in your Notion database
• An AI provider — to generate a reply (e.g. NVIDIA, Groq, Mistral, OpenRouter, or a local model via Ollama / LM Studio)
• A custom webhook URL — to a destination you configure yourself
• On-watch local storage — stored only on your Pebble device

No note text is ever sent to any server operated by the developer.

Google OAuth & Google Tasks

If you connect Google Tasks, Brain Dump uses OAuth 2.0 to request read/write access to your Google Tasks (https://www.googleapis.com/auth/tasks). The OAuth flow is:

• Initiated from the app's settings page on your phone
• Completed in your system browser (Chrome or Safari)
• Tokens (access token and refresh token) are stored locally in the Pebble app's settings storage on your phone — they are never transmitted to any third-party server

Brain Dump only uses your Google Tasks access to create tasks. It does not read, list (beyond fetching your task list names for the settings dropdown), modify, or delete existing tasks.

You can revoke access at any time from your Google Account permissions page or by tapping Disconnect in the app settings.

AI providers

If you enable the AI Agent destination, the text of your note is sent to the AI provider you configure (e.g. NVIDIA NIM, Groq, Mistral, OpenRouter, or a local model). The API key you supply is stored locally on your phone and is never shared with anyone other than the provider you chose. Refer to your chosen provider's privacy policy for how they handle request data.

Third-party services

All third-party integrations (Google, Notion, webhooks, AI APIs) are opt-in and configured entirely by you. Brain Dump acts only as a local relay between your voice and the services you explicitly connect.

Data collection

The developer does not collect, store, or have access to:

• Your voice recordings or transcriptions
• Your Google account data
• Your Notion content
• Your AI conversations
• Any analytics, crash reports, or usage data

Children's privacy

Brain Dump is not directed at children under 13 and does not knowingly collect information from them.
