Overview

Pryme is a Chrome extension built by Keystone Automation Co.. We take your privacy seriously. Pryme stores your context cards locally on your device only. We do not collect, transmit, or store any personal data on external servers.

Data storage

All context cards you create are stored locally on your device using Chrome's built-in chrome.storage.sync API. This data never leaves your device and is never sent to our servers.

Clipboard usage

Pryme writes to your clipboard only when you explicitly click the "Pryme it" button. We never read the contents of your clipboard at any time.
