Frequently Asked Questions

- Pro and Business are billed monthly (cancel anytime) or annually (two months free on the yearly plan). Business is priced per seat. All recurring payments are managed via our secure payment portal — Stripe.

We only store your name, email address, and snippets, which can be removed by request anytime. We comply with Google's security standards for Google Workspace™ add-ons.
- We're here for you. All users get access to our online documentation and contact forms. We also love feedback — many of our newest features came directly from user suggestions. Business customers get priority support, and Enterprise customers get a dedicated account manager.
