Accepting push notifications stores a unique number on the phone; is this a security risk?

Apple push notifications are used to notify you that you have an incoming call, or a text/email message has arrived in MySudo. If you do not accept push notifications, you will not be notified of incoming calls or that new messages/emails have arrived.

So that Sudo Platform can send push notifications for new incoming messages, incoming calls and other events, Sudo Platform stores a unique identifier generated by the mobile device provider (e.g. Apple). This unique identifier allows Sudo Platform to send messages via the mobile device provider’s push notification service. This mechanism does not reveal the device’s serial number or IMEI number, or the user’s Apple ID or other personally identifiable information to Anonyome Labs.

All network communications between Sudo Platform and the push notification services, and the mobile devices and the push notification services are encrypted using transport-level security (TLS).

The data sent in MySudo push notifications is encrypted so that it can only be decrypted by the receiving user’s private key. This makes the notification payload opaque to mobile device providers such as Apple or Google and other intermediaries.
