Cancel-By Reminder

No bank link, and that is the point

Subscription trackers usually work by connecting to your bank or card and watching the charges. That means handing a company access to every transaction you make in order to catch a handful of renewals.

This reads what is already in your inbox instead. It cannot see your finances because it never touches them, and there is no account to create and nothing to connect.

How it avoids false positives

Two conditions must both hold. First, a commitment phrase: not the word "trial" on its own, which appears in every marketing email ever sent, but wording describing an arrangement you are already in, like "your free trial ends", "renews on", "cancel by" or "unless you cancel". Second, a real future date near that phrase.

Wording that means the opposite disqualifies the message outright: "start your free trial", "try it free for 30 days", "your trial has ended", "cancellation confirmed". That filter does most of the work.

When it does save something, a card confirms what it found with a "Not a trial" button, so a mistake takes one click to correct and is never re-added for that message.

Picking the right date

Emails often carry several. Candidate dates are scored by how close they sit to the phrase that made them interesting, so in "your plan begins on September 2 and will automatically renew on October 15" the date beside "renew" wins. Dates already in the past are ignored, since a cancel-by date that has passed is not actionable.

It reads September 3, 2026, 3 September 2026, 2026-09-03, 09/03/2026, and relative phrasing like in 14 days.

One honest limit

A browser extension can only read what the page has rendered, so this checks messages you open. It cannot sweep an entire mailbox, because that would need the Gmail API and a linked account, which is the exact thing this product exists to avoid. In practice that works, because the emails that matter are the confirmations you open anyway when you sign up.

Permissions

Gmail only, plus storage, alarms and notifications. It reads a message when you open it, in the tab, to look for subscription wording and a date. Nothing is sent anywhere. Saved reminders hold a service name, a date and a link back to the thread, and are deleted a week after the date passes.
