1NIP-782======34Arbitrary custom app data5-------------------------67`draft` `optional`89The goal of this NIP is to enable [remoteStorage](https://remotestorage.io/)-like capabilities for custom applications that do not care about interoperability.1011Even though interoperability is great, some apps do not want or do not need interoperability, and it wouldn't make sense for them. Yet Nostr can still serve as a generalized data storage for these apps in a "bring your own database" way, for example: a user would open an app and somehow input their preferred relay for storage, which would then enable these apps to store application-specific data there.1213## Nostr event1415This NIP specifies the use of event kinds `30078` (an _addressable_ event) with a `d` tag containing some reference to the app name and context -- or any other arbitrary string. `content` and other `tags` can be anything or in any format.1617It also defines the kind `78` (a _normal_ event) for when the app needs to store and query multiple events of the same type. Apps should use some unique tag (even a `d` tag) for grouping these events together.1819## Some use cases2021 - User personal settings on Nostr clients (and other apps unrelated to Nostr)22 - A way for client developers to propagate dynamic parameters to users without these having to update23 - Personal private data generated by apps that have nothing to do with Nostr, but allow users to use Nostr relays as their personal database
