It can be frustrating trying to figure out how to remove your email address from Square, especially if you never gave it to them in the first place, and you are trying to invoke a ‘right to be forgotten’.

Chances are very good that, in 2017, you have encountered a merchant that uses the Square payment system (often presented on an iPad that swivels around so that you can sign the check, include a tip, etc.). Square is very popular in coffee shops and fast food places. And, if you have ever paid through the Square system, you may be wondering how to change or remove your email address from the Square system.

“How did this store get my email address to send me a Square receipt?” asks a reader. “I paid for something at a new store that had the Square iPad checkout thing. I never gave the store my email address, but within seconds I had an emailed receipt. How the heck did Square get my email address?” laments another. Here’s how.

Snapchat, the “now you see it now you don’t, but it didn’t really disappear” company, has partnered with Square, the money people, to provide a new mobile payment service called Snapcash. Of course, it’s really just Square, private labelled for Snapchat.

Paying for your morning latte just got easier with the new Pay with Square app, which allows users to pay for purchases without swiping their credit card. Instead, users can pay for their purchases directly with their Android or iPhone. The app can be downloaded directly from the Apple App Store or Google Play. Users must be running at least iOS 4.1 or Android 2.2 in order to use the app.
