Warns about dark patterns at checkout and quietly keeps your own record of what you consented to. ColdStamp is a quiet helper for online checkouts. It does two things, both entirely on your device. 1. It warns you about dark patterns BEFORE you click. On any checkout page, a small panel in the corner flags: • A recurring or auto-renewing option that's already ticked for you. • A free trial that quietly converts to a paid plan. • A recurring price shown in much smaller or fainter type than the headline. • An order total that's bigger than the items add up to. • A "no" button worded to make you feel bad for declining. The panel is informational. It does not change the page, submit anything, or interfere with checkout. You can dismiss it. 2. It can keep your own record of what you agreed to (optional, off by default). When you click a primary checkout button — Subscribe, Start free trial, Place order — ColdStamp can snapshot the page at that moment: which boxes were ticked, what prices were visible, what the payment request actually said. The snapshot is stored locally on your device. Card numbers and CVVs are redacted before anything is saved. You can export any snapshot as a JSON file and use it however you like — for example, attaching it to a chargeback claim. Why this exists. Subscription vendors keep structured, timestamped logs of every signup. When something goes wrong, they show up to disputes with logs and screenshots. You show up with a vague memory. ColdStamp is the user's side of that record. It does not file disputes for you, does not connect to your bank, and does not cancel subscriptions. It just makes sure that when you need to prove what the page actually said, you can. What ColdStamp does NOT do. • It does not transmit any data over the internet. No accounts, no servers. • It does not collect your name, email, card number, or browsing history. • It does not auto-cancel subscriptions or auto-file disputes. • It does not connect to your bank or payment provider. Privacy. Everything ColdStamp captures stays in your browser. There is no ColdStamp server. The full privacy policy is linked below. Source.
