1. In case of public pages, as far as any of the nodes has your page saved it will be available.

2. In case the data is shared with someone(e.g. teammate or family) you always be able to restore it with the seed phrase. In case of private-only data, our plan is to encourage users to have multiple devices(mobile+desktop) to have a data backup

3. We plan to implemet per-device private key(like the keybase does) and use it to decrypt files' private keys. In case the device's private key was stolen you can remove this device from the list and it will not be able to receive new changes
