Common Questions

Do I need to sign up or give an email?

No. The calculators work without an account or an email.

What happens to the numbers I enter?

They are saved without your name, email or company, and added to the anonymous data on company pages, like what teams pay and how much of a tool they use. You can skip the optional questions.

Are the results estimates?

The renewal check compares your quote with real bills other teams shared. The Build vs. Buy estimator gives estimates, and they are labeled as estimates.

How the numbers are used: methodology and privacy policy.
