By accessing and using our apps, you (“User”) acknowledge that you have read, understood, and agree to be bound by these Terms and the Privacy Policy. If you do not accept these Terms and the Privacy Policy, you are not authorized to use the Services.


Math Easel takes your privacy seriously. You may opt to grant our apps access to your current location (“Location Information”) as set forth in the Privacy Policy. Math Easel may also automatically collect anonymous information regarding your interaction with, and use of, our apps. By using our apps, you agree that Math Easel may collect and use this information as set forth in the Privacy Policy.


Some parts of the Applications are billed on a subscription basis ("Subscription"). You will be billed in advance on a recurring and periodic basis ("Billing Cycle"). Billing cycles are set either on a monthly or annual basis, depending on the type of subscription plan you select when purchasing a Subscription.

Your Subscription will be charged to your iTunes account at confirmation of purchase. Your Subscription will automatically renew at the end of your Subscription period unless canceled at least 24 hours prior to the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period.

You can manage your Subscription or turn off auto-renewal at any time from your iTunes account settings. Cancellation of the active Subscription period is not allowed.

All Subscriptions may be final and non-refundable. By accepting these terms, you agree that Math Easel is not required to provide a refund for any reason.

Math Easel may change, modify, or eliminate features of the Subscription at any time, with or without notice. Specifically, Math Easel may from time to time change weather data providers as a result of pricing changes, changes to the terms of use, or other reasons. Math Easel does not warrant that any particular weather provider will be available in the future. You agree that Math Easel will bear no liability to you or any third party if Math Easel does so.

Subscription Fee Changes

Math Easel, in its sole discretion and at any time, may modify the Subscription fees for the Subscriptions. Any Subscription fee change will not go into effect automatically; you must opt into the fee change to continue using the Subscription after the end of the then-current Billing Cycle.
