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
CancelProof documents your cancellations — it never cancels anything for you and never guarantees a refund. It's your record-keeper.
Add your subscriptions and get a heads-up 7, 3, and 1 days before every renewal — and on the day itself.
Start Proof Mode and CancelProof captures a timeline, the pages you saw, and screenshots — with sensitive fields automatically hidden.
Charged after cancelling? One click assembles a professional refund & dispute pack you can send to the merchant or your bank.
Your data never leaves your device. We don't sell it, run ads, or track your browsing.
Subscriptions, screenshots, and records are stored in your browser — never uploaded to our servers.
Every documented cancellation produces a timestamped evidence PDF, saved to your device.
Passwords and card numbers are automatically covered before any screenshot is taken.
Smart reminders before each charge, with recovery even if your browser was closed.
Step-by-step guides for cancelling popular services, plus what to do if you're charged after cancelling.
More guides coming soon — Adobe, YouTube Premium, HBO Max, Amazon, and more.
CancelProof is launching soon on the Chrome Web Store. Leave your email and we'll let you know.
