I often get people in shops ask for my email to send the receipt to, a paper receipt isn't even an option they offer. Thankfully when I ask for a paper receipt it's not usually a problem either. If I've just paid for the product, why would I want to give them my email address? Someone needs to make a receipt aggregator or something.
There are receipt aggregators; there's no reason to trust them though. There's too much of an amount of money to be made in this niche and thus no reason for any company to provide a honest solution.
Yeah that's fair, I should have elaborated and said "someone should make a privacy friendly one". I don't even care much about long term storage, I just want to be able to scan a QR code generated at check-out and have it loaded onto my phone.
You're likely right about there not being a good reason to provide an honest solution.
