Pro is a monthly or yearly subscription, price shown before payment, cancel anytime from the extension. Payments are handled by ExtensionPay and Stripe.

Honest note: automated checks find part of the accessibility barriers (often 30–50 %). Keyboard use, screen reader behaviour and content clarity still need a manual review.
