What Patina is

Patina is a Mac app that helps you stay organized by connecting to your calendar, email, and messages. It gives you daily briefings, keeps notes on the people in your life, and tracks your goals.

Data we collect

Patina stores your data locally on your device. When you connect Google Calendar or Gmail, we request read-only access to your calendar events and email. This data is used solely to provide you with summaries and context inside the app.

How we use Google data

Patina accesses Google Calendar and Gmail with the following permissions:

• calendar.readonly — Read your calendar events to show your schedule
• gmail.readonly — Read your email to surface relevant messages in briefings
• email — Identify your Google account

Patina's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Data storage

Your files are stored locally on your Mac in a folder you choose. If you opt into GitHub sync, your data is pushed to a private repository only you control. OAuth tokens are stored in your macOS Keychain.

Data sharing

We do not sell, share, or transfer your personal data to third parties. Your calendar events and emails are processed locally on your device. The only external service Patina communicates with is Anthropic's API to power the AI assistant.

Data retention

All data stays on your device until you delete it. Disconnecting a service immediately removes its stored credentials. Uninstalling Patina removes all app data.

Security

OAuth tokens are stored in your macOS Keychain. All API communication uses HTTPS. The app uses hardened runtime and is notarized by Apple.
