Privacy Policy

Last updated: February 26, 2026

Summary: Bruin Notes does not collect, store, or transmit any personal data to external servers. All your notes and data stay on your device.

Data Storage

All data created in Bruin Notes is stored locally on your device in a SQLite database. This includes:

Notes and their content
Tags and organizational metadata
Task and workflow data
App settings and preferences
Search embeddings (computed on-device)

iCloud Sync

If you choose to enable iCloud sync, your notes are synced as Markdown files through Apple's iCloud Drive infrastructure. This sync is:

Optional — you can use Bruin entirely offline
Managed by Apple's iCloud service and subject to Apple's Privacy Policy
End-to-end encrypted by Apple when Advanced Data Protection is enabled

Bruin does not operate any sync servers. The sync happens directly between your devices via iCloud.

AI and Embeddings

Bruin's semantic search feature uses a machine learning model (all-MiniLM-L6-v2) that runs entirely on your device. No note content is sent to external AI services for embedding computation.

When you connect external AI agents via the MCP (Model Context Protocol), those agents may process your note content according to their own privacy policies. Bruin itself does not send data to any AI service.

Webhooks

If you configure webhooks, Bruin will send event notifications to the URLs you specify. This is entirely under your control — no webhook data is sent unless you explicitly configure it.

Data Collection

Bruin Notes does not:

Collect analytics or usage data
Use crash reporting services
Include advertising SDKs
Track your behavior
Share data with third parties
Require account creation

Third-Party Services

Bruin Notes contains no third-party SDKs, analytics tools, or advertising frameworks. The only external service interaction is Apple's iCloud, which is optional.

Children's Privacy

Bruin Notes does not knowingly collect information from children under 13. The app does not collect information from any user.

Changes to This Policy

If we update this privacy policy, we will post the changes on this page and update the "Last updated" date. Since Bruin does not collect any contact information, we cannot notify users directly of changes.
