Essential Upsell & Cross Sell

Check their new permissions... They want all of your customer data. Ah, yea, no thanks. YOU ARE OUT OF YOUR MIND and Shopify should not even allow this. This app may be free, but is it really worth it at the cost of your customers data going to Lithuania? The best thing you can do is report this app to Shopify.

From their permissions:
View personal data
Customers
Name, email address, phone number, physical address, geolocation, IP address, browser and operating system

Update: They recently updated their ToS and now require full access to customer personal information and all orders for last 60 day. I take my customer data protection serious and do not see why they need this info. Moving to 1 star and unnstaling. Here is what the ToS is :

View personal data
Customers
Name, email address, phone number, physical address, geolocation, IP address, browser and operating system
View store data
View orders
All order details for the last 60 days

I 100% recommend this app for cross-sell. This app is simple and effective. I have been using it for the cross-sell functionality and it has led to a purchase of the cross-sell every time!
