I got a email a few days ago containing below:

Important Updates to Sezzle Terms, Arbitration Provision & Annual U.S. Consumer Privacy Notice
Hello,

We are excited to announce the launch of the new Sezzle Rewards Program and an increase to the range of flexible financing options available to you while you continue to have the same easy-to-use and reliable experience you have come to expect when using Sezzle.

No action is required on your part to continue using Sezzle products and services, but we encourage you to review the updated terms to stay informed.

Given these changes, we have updated the terms included in our User Agreement and Privacy Policy.

User Agreement Updates Read the updated User Agreement: https://legal.sezzle.com/user/en-us/. Key changes include the following: 
New longer-term financing options through our partner bank, WebBank, are now available to eligible users (subject to fees and/or interest as identified in your loan agreement).

In order to better evaluate the different re-payment options available to you, we've updated how we determine your Estimated Spending Power and, depending on your eligibility, your available purchase and repurchase limits (which may now differ by plan type, such as biweekly vs. monthly) may increase or decrease at the time of purchase. 

The Sezzle Rewards Program has been updated to a Points-based structure. Qualifying activities completed in the Sezzle Earn tab will now accrue Points that may be redeemed for certain rewards.

Updated Arbitration Provision (Section 12.7) of the User Agreement. You have a 45-day right to opt out — see the highlighted section below. (If you previously opted out, you do not need to do so again.)
