What payment methods do you accept?
We accept all major credit cards through Stripe, our secure payment processor. We never see or store your card details.
Is my data safe?
Yes. All our add-ons process data within Google's infrastructure. We don't store your spreadsheet, email, or form data on external servers. See our Privacy Policy for details.
