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.
All context cards are stored using Chrome's built-in chrome.storage.sync API. For free users, data stays entirely on your local device. For Pro users, chrome.storage.sync automatically syncs your cards across devices using Google's encrypted infrastructure — this is Google's own sync system, not Pryme's servers. Keystone Automation Co. never has access to your data at any point.
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.
Pryme requests the following permissions and uses them only as described:
Pro subscriptions are handled by ExtensionPay.com and Stripe. Keystone Automation Co. does not store or have access to your payment information. View ExtensionPay's privacy policy at extensionpay.com.
Pryme uses ExtensionPay.com for subscription management. No other third party services are used.
If our privacy practices change we will update this page with a new date. Continued use of Pryme after changes constitutes acceptance of the updated policy.
