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 collect anonymous usage events to understand how the extension is being used and improve the product. No personally identifiable information is ever collected or transmitted.
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.
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 Google Analytics 4 to collect anonymous usage events (such as feature interactions and upgrade screen views). This data contains no personally identifiable information and is used solely to understand how the product is being used. Each installation is assigned a random anonymous identifier. No user names, emails, or card content are ever transmitted.
Pryme uses ExtensionPay.com for subscription management and Google Analytics for anonymous usage measurement.
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.
