Over the past week or so I came across a few posts on here that pertained to online scams and how a few people were tricked by scamming tactics, so thought I'd mention a few apps that might be worth looking into. Email scams have increased over the last two months, most of which are phishing attempts that contain a potentially malicious link, so it's advised to only open an email that comes from an address you are familiar with and or do business with, and quarantine suspicious emails in the spam folder. I understand that Google and Apple often require smartphone users to have a Gmail or Yahoo email account setup in order to download apps from their respective app stores, but it might not be a bad idea to have a backup email address with a different provider as Gmail and Yahoo email addresses are public and thus easier for scammers to target. A reliable (and free to use basic package) email provider that I would recommend in addition to the others mentioned above would be ProtonMail. With servers based in Switzerland and email communications encrypted if both parties use it, ProtonMail would be ideal to handle business and shopping accounts with. The main functions of ProtonMail are free to use with optional paid upgrades for those who may want extra features like more than one address or additional archive storage space, and the same developers also have a VPN app called ProtonVPN that could be used with a current ProtonMail account, so that way you could have both a good email and VPN service with one account. Just thought I'd mention that here, and lastly you might want to check out an app called Signal which encrypts text messages and phone calls provided both ends use it. Those are a few suggestions to help with privacy concerns, and there is no shortage of scams going around.
