They stay with you, on your Phone, like all your personal data. We don't even know who you are. Self gives you: DIGITAL FREEDOM - You can use Self to prove you are the right human just by being you. Instead of passwords, seed phrases or *** *** codes sent by SMS, Self lets you prove you are you, and does it without disclosing your personal data to whoever wants to check (unless you agree to). Now you can prove your age, prove you approved a payment or logged into a service all without needing to share private, personal data. SECURE COMMUNICATION- Self calls and messages are end to end encrypted, and only between verified people and companies you have agreed to communicate with. No more wondering if a call is genuine or from a scammer, or if that message is a phishing trick or an AI-powered marketing bot. AN ADVANCED WALLET - The companies you buy from can help protect your personal data by storing any they hold with you, in your Self wallet. Now you're not at risk if they get hacked, and you can trust them when they communicate with you through Self, instead of wondering if the email you got was really from your bank. CRYPTOGRAPHIC PROOF - Because Self lets you prove who you are, it takes messages beyond communication, now you can sign them, prove you've seen them, prove you've been somewhere, prove you're with someone, all without disclosing any data you don't want to. CONTROL OF YOUR DATA - With Self your personal data is only stored by you, on your phone or in your backup and always encrypted end-to-end. It's not in our database, because we don't have one. It's in your hand and it can only be shared with someone if you choose to share it. You are in control.
