Free core, optional Premium

StatRise is a study aid for learning statistics. The core is free with no account. An optional Premium subscription (weekly, yearly, or lifetime) unlocks the full calculator, lesson, practice, simulation, and Data Lab sets, and is provided as-is.

Refunds

Not happy with a purchase? Email [email protected] within 14 days of a first purchase, or within 7 days of a renewal, and we will refund it. Send the message from the email address you used at checkout, and include:

  • the email address used at checkout (if you are writing from a different address)
  • your access code, shown on the Premium page while you are signed in on the browser you purchased from
  • roughly when you purchased, and which plan (weekly, yearly or lifetime)
  • the last 4 digits of the card, if you have the receipt handy

That is everything needed to find the purchase and process the refund. This policy does not limit any statutory rights you may have.
