Renewal Check Studio

Renewal Check Studio is a subscription list you keep yourself. After buying it you get a ZIP with one HTML file and a quick-start guide. Open the file in a browser, add each subscription by hand with its price, how often it bills, the renewal date and the notice period, and the app works out the rest. It shows estimated monthly and annual equivalent costs, moves the expected payment date forward each cycle, and calculates a notice deadline, the last day to act before a contract renews.

The review view gathers renewal dates that need updating and decisions due within 30 days. You can label each subscription Keep, To review or Cancelled, and cancelled ones drop out of the active totals. A payment method can be noted by nickname, such as a card or wallet name, without entering any numbers.

Everything stays in the browser's local storage, and the file itself doesn't hold your saved list, so the store page recommends exporting a JSON backup before moving the file or clearing browser data. It also points out that the backups contain your entries and should be kept private.

The listing is open about what it doesn't do. The file does nothing while closed, so there are no reminders, emails or calendar exports, and it has no bank connection or device sync. Renewal dates and notice periods stay manual, currency labels don't convert amounts, and the cost figures are estimates rather than a payment forecast.

It costs $15 as a one-time purchase on Payhip, sold by Support Studios, and the interface is available in English, French and Spanish. A free interactive preview with sample subscriptions lets you try the date calculations before buying.
