We are powered by Stripe and they accept all major debit and credit card payments(Visa, American Express, Mastercard) and other local payments solutions.
tabExtend will pay the local sales tax out of our end so no, you don't need to pay any sales tax.
We are a bootstrapped company and to cover our cost and keep development going we have chosen a paid plan over selling data, showing advertisement, or implementing malicious third-party code into the product. If tabExtend saves you only a few minutes a day it will quickly add up and benefit you enough to hopefully be worth the price.
All payments and security are handled by Stripe. We never see or touch your credit card information. Stripe is PCI-certified and all card numbers are encrypted at rest with AES-256, read more at stripe.com
If you for any reason want to cancel your plan we have a 30-day full refund policy.
