The extension needs an active subscription to connect to your account. You manage your plan from the panel, under Settings → Subscription.
Free trial
A new account gets one 3-day trial on Pro or Ultra. In Settings → Subscription, pick a plan and open Stripe Checkout to save your card. The extension works normally during the trial. After 3 days Stripe charges the monthly fee unless you cancel first.
Activation
If you already used your trial, click "Buy Vintly Pro" or "Buy Vintly Ultra" to open Stripe Checkout. After payment, the subscription activates automatically. The extension refreshes its licence the next time it connects on Vinted.
Renewal and cancellation
The subscription renews automatically each month. Cancellation, invoices, and your card are in the Stripe portal ("Manage subscription"). After you cancel, access continues until the end of the paid period.
Subscription history
Every activation, renewal, and cancellation is logged in the history table on the settings page, with the date and the period it covered.
