Coming soonChrome Extensions
Here we introduce the Chrome extensions we develop and offer. For every extension, feature data is stored only in your browser (chrome.storage.local) and never sent to any external server. Payments are handled by ExtensionPay (a payment service backed by Stripe); this site and its developer never handle your card details directly. See Privacy Policy for details.
