[FEATURE]Save user content locally

[hhbisheng]

Can Amethyst save the content and replies it sends locally?
I heard that the repeater will clean up old tweets, and I am worried that the content I send out may be lost as there may be some important content inside.
The content of Nostr is mainly text and does not take up much space.
The current phone memory is sufficient to store these texts.
I think a normal user, even if they save all the content sent out within ten years, should not occupy 1GB.
So can Amethyst consider providing a feature to save their own articles and replies locally?

For now you can try using Citrine. It's a local relay you can install on your phone.
There's a local relay section in amethyst relays settings

Well, that's great, but the isolated mode of Nostr relays makes me feel like I'm using a local area network. I've considered using other software instead, but currently there's no good solution.
I think Briar may be a choice, although Briar may not seem as convenient as Nostr. I am looking forward to other software that is more conducive to information exchange, such as IPFS's Berty? Well, it seems that we still need to wait for a considerable amount of time.
