SubSentry: Subscription Saver

Save and track subscriptions and free trials so you don't forget to cancel.

SubSentry: Subscription Saver helps you stop getting hit with surprise charges from free trials and subscriptions you forgot about. Whenever you are on a subscription or free-trial page (streaming, apps, SaaS, anything), open the SubSentry popup and click “Save this subscription.” The extension scans the page, grabs key details like the site, price, billing cycle, and any “7-day free trial” style text, then saves it with an estimated cancel-by date. In the popup, you get a simple dark dashboard that shows all your saved subs and trials in one place. Entries are sorted by upcoming renewals, with small “coming up” or “past due” warnings so you can quickly see what needs attention first. Clicking a saved item opens the original page again, so it is easy to review or cancel. SubSentry is designed to be fast, quiet, and ADHD-friendly: one button, clear status messages, no extra setup, and no accounts to create. Everything is stored locally in your browser using Chrome storage; your subscription data is not sent to any server. If the extension helps you dodge a fee or feel more on top of your money, there is an optional tip section that links to the creator’s Cash App so the tool can stay free for everyone.
