Stop being surprised
by renewal charges.

Option 1 — Browser extension (lowest effort, highest reliability)

Install a tracker extension once. From then on, every time you sign up for a new subscription, open the extension and one click pins the renewal date. The extension emails you 3 days, 1 day, and the day of renewal.

RefundFlow does this for free, stores data locally in your browser, and never asks for an account. The capture flow takes about 8 seconds on a typical merchant signup page.

• Pros: works automatically once set up; multiple reminder dates; covers annual plans.
• Cons: requires installing once — but you'll never have to think about it again.

Option 2 — Calendar reminders

When you sign up for a new subscription, immediately add a calendar event 3 days before the renewal date with a [Cancel?] prefix. Google Calendar, Apple Calendar, Outlook — any of them work. The downside is you have to actually remember to do this every time, which most people don't.

Option 3 — Bank app notifications

Chase, Bank of America, Apple Card, and Capital One all let you turn on alerts for recurring charges. The problem: they alert you after the charge, not before. Useful as a safety net to catch the first charge inside the refund window — useless for prevention.

Combine all three

Defense in depth wins. The extension is your front line because it captures on signup. Calendar is your manual backup. Bank notifications are the last safety net — if a charge slips through, you still catch it in time to refund.
