A quiet sweep of your own mailbox for money that is about to move. Trial Radar is a Chrome extension that reads your mail locally, finds recurring charges and free-trial periods, and lists everything that will be charged in the coming seven days, each entry with a one-click path to the cancel page. Nothing is uploaded and no account is created: the scan runs inside the browser and the data never leaves the device. The free tier covers subscription detection, seven-day warnings, the open-cancel-page button, cheaper alternative suggestions, and plan comparison cards, which is enough to end a trial in seconds instead of hunting through a support inbox after the card has already been hit. A planned Premium tier adds cancel-for-you letters, refund request letters for trials that were already charged, and advance warnings before annual renewals. The business model is user-friendly by design: the tool is free, and it is monetized through referral rewards from the cheaper alternatives it suggests, never through selling user data. It fits anyone who signs up for free trials and loses track of them: streaming services, productivity apps, AI tools with trial periods, gym and delivery subscriptions. For people who review their subscriptions once a year and still get surprised, this is the recurring-charge inventory that updates itself. Maker: Vlad Kovnerov, who builds browser tools that keep data on the device.
