Checkout is hosted by Polar, a fully-featured merchant-of-record. They
handle VAT, receipts, refunds.
After payment you receive a license key via email.
Paste the key into the extension popup's License key field → Apply.
Green check mark = activated. The paid features unlock immediately.
All conversation data stays on your machine throughout this flow. Polar only ever
sees your email, payment details, and the license key — never your Claude content.
Payment methods

All major credit cards (Visa, Mastercard, Amex, Discover).

Refund policy
30-day money-back guarantee, no questions asked. Email hello@aichatarchive.app
with your license key.
Refunded licenses are revoked; the extension checks revocation status when it
validates the license. After revocation, the extension returns to free-tier
behavior. Already-exported files are yours to keep — we have no way to take them
back, and we wouldn't want to.
