About Perkmon

Perkmon helps you turn card offers into something you can actually remember to use. The Chrome extension lets you add eligible credit card offers, supported loyalty snapshots, and merchant reminders to your Perkmon account while you are already signed in on provider websites. Use Perkmon to: - Save eligible issuer offers without manually copying offer terms or expiration dates. - Match offers to the right card using card names and last four digits. - Keep supported loyalty snapshots current, including points, miles, status, and progress. - Get local reminders when a merchant you visit may match one of your saved offers. - Review what was found before keeping it in Perkmon. Typical flow: 1. Sign in to Perkmon in the extension. 2. Open a supported issuer, loyalty program, or offer page. 3. Sign in on the provider's own website. 4. Use the Perkmon side panel to start a sync. 5. Review the results and continue tracking them in Perkmon. Privacy and control: - Perkmon does not ask for, collect, or store issuer passwords. - Perkmon does not collect CVVs, full card numbers, or full bank account numbers. - Sync starts from the Perkmon side panel on supported provider pages. - Merchant reminders are based on offers saved in your Perkmon account. - Perkmon does not browse unrelated websites in the background. - We do not sell your personal data. Why Chrome asks for website access: Chrome may show broad website-access language because Perkmon needs to recognize supported issuer, loyalty, offer, and merchant pages. The extension still limits its behavior to supported provider syncs and local merchant reminders for saved Perkmon offers.
