An alias email address is a unique email address generated by Privowny App for the purpose of anonymizing your real email address.
When you subscribe to online services (newsletters, products trials, …) that require email addresses, you can use the Alias Manager to generate a unique email address assigned to you for the service you are subscribing to.
Whenever the service sends you emails, it will use your alias and Privowny App will forward these emails to your primary email address.
This way, you no longer have to share your real email address in these situations. You can use aliases that protect your personal data.
