Introduction

Prism ("we", "our", or "the extension") is committed to protecting your privacy. This Privacy Policy explains how we handle your information when you use our Chrome extension.

Data Collection

We do NOT collect any personal data. Prism operates entirely on your device and does not transmit any user data to our servers.

Data Stored Locally

The following data is stored locally on your device using Chrome's storage API:

Data Type	Purpose	Storage Location

Database Configuration	Store your database preferences	Local
Field Mappings	Remember your custom field settings	Local
Offline Queue	Store pending captures when offline	Local
Usage Statistics	Track daily capture count	Local

Data Sharing

We do NOT share your data with any third parties.

The only external communication is between the extension and Notion's official API, which is necessary to save your captures. This communication is:

Initiated only when you explicitly click "Send to Notion"
Encrypted via HTTPS
Subject to Notion's own privacy policy

Third-Party Services

All sensitive data (like your Notion Token) is encrypted using AES-256
Data never leaves your device except when explicitly sent to Notion
