Never pay for a subscription you already cancelled.
CancelProof reminds you before every renewal, records tamper-evident proof when you cancel, and builds a refund pack if you're ever charged anyway.
Local-first · Your subscriptions and screenshots stay on your device
Three steps to never being charged by surprise
CancelProof documents your cancellations — it never cancels anything for you and never guarantees a refund. It's your record-keeper.
Track & get reminded
Add your subscriptions and get a heads-up 7, 3, and 1 days before every renewal — and on the day itself.
Record proof when you cancel
Start Proof Mode and CancelProof captures a timeline, the pages you saw, and screenshots — with sensitive fields automatically hidden.
Get your refund pack
Charged after cancelling? One click assembles a professional refund & dispute pack you can send to the merchant or your bank.
Built to be your proof
Track renewals, record the cancellation, and export a refund pack — all from your browser.
Private by design, built for proof
Your data never leaves your device. We don't sell it, run ads, or track your browsing.
Local-first
Subscriptions, screenshots, and records are stored in your browser — never uploaded to our servers.
Tamper-evident PDF
Every documented cancellation produces a timestamped evidence PDF, saved to your device.
Sensitive fields hidden
Passwords and card numbers are automatically covered before any screenshot is taken.
Never miss a renewal
Smart reminders before each charge, with recovery even if your browser was closed.
