Trial Watch — Free Trial Countdown par Swalter Factories

Firefox Add-on DescriptionTrialWatch is the only browser extension that makes sure you never get surprise-charged by a forgotten free trial again.The moment you sign up for a free trial — Netflix, Spotify, Adobe, Hulu, any SaaS tool, anything — you log it in one click. TrialWatch tracks the countdown and fires a browser notification 3 days before the trial ends, then again the day before, so you have time to cancel consciously instead of waking up to an unexpected charge on your statement.When you visit a page that looks like a free trial sign-up, TrialWatch automatically detects it and offers a one-click "Track this trial" button so you never forget to log it in the first place.Features:

Browser notifications fire 3 days before expiry, 1 day before, and on the end date itself

Smart page detection — automatically offers to track a trial when you're on a sign-up page

TrialWatch collects absolutely nothing. It never reads your payment information, never accesses your bank or credit card details, never connects to any server, and never transmits any data anywhere. All trial data is stored exclusively in your browser's local storage on your device. The extension has no backend, no account system, and no analytics of any kind.
