Questions about a fee, a bug, billing or an idea for a new tool. Write to us and a real person will answer.
Billing and subscriptions
You can cancel, change your card and download invoices yourself in the billing portal. Sign in with the email you used at checkout.
A fee looks wrong
Tell us the platform, the page and what you expected. We check it against the platform's official fee page and update the calculator if it changed.
Paid tools stopped working
Paid tools are unlocked per browser. Open the welcome link from your purchase in the new browser, or email us your checkout email and we will send it again.
