The opposite of the apps that read your whole inbox.
Never your bank.
We read receipts sent to your canary address. We have no connection to any bank, card, or balance — there's nothing to connect.
Never sold.
Not your address, not your subscriptions, not aggregate anything. No ads, no data brokers, no training. You are the customer, not the product.
Delete everything, instantly.
Every message is yours to export or delete the moment you want — no ticket, no waiting, no asking us. It just goes.
Remember when Unroll.me sold users’ inbox data? TrialCanary can’t. It never touches your real inbox — a service mails your canary address directly, or you forward it a receipt. That’s the whole surface.
Three steps. Then it runs itself.

Small, sharp features. No busywork.
Countdown chirps
A chirp three days before a trial converts, and again the day before — “$17.99 on July 25”, never “renews soon”.
Cancel deep-links
Every chirp carries a direct link to the exact cancel page — no digging.
Price-change alerts
When something you already pay for quietly goes up, you hear about it.
Manual & screenshot add
Already paying for something? Type it in plain language — “Spotify $11.99 monthly” — or drop a screenshot. We’ll track it too.

No bank. No inbox access. No catch.
The honest answers to the things people ask before they trust an app with anything near their money.
Do you connect to my bank?
No — and we can't. TrialCanary has no connection to any bank, card, or balance. We only read receipts sent to your canary address. There's simply no bank to see.
Do you read my real inbox, like Unroll.me did?
Never. We have no access to Gmail, Outlook, or any mail account. A service mails your canary address directly, or you forward us a receipt yourself. That's the entire surface — nothing else is visible to us.
What do you actually keep, and for how long?
Mail to your canary address is kept 90 days by default, and it's yours to export or delete instantly. Once a receipt is parsed we delete the body, keeping only the service, amount, and date. Anything you forward that isn't a receipt is deleted within 24 hours.
Is my data sold or used to train AI?
No. Nothing is sold — not your address, not your subscriptions, not aggregate anything. Nothing trains AI, ours or anyone else's.
What stays free if I don't pay?
Your canary address and everything in it — reading mail, grabbing OTP codes, exporting, deleting. The inbox is free forever and is never paywalled. Pro adds the tracking and chirps.
