## What it is
ImmortalDB is a resilient key-value store for the browser that redundantly persists data across Cookies, IndexedDB, and LocalStorage. It uses a consensus mechanism to detect and self-heal deleted or corrupted data via a simple Promise-based API.

## Use cases
- persist key-value data in the browser that survives cache clearing
- store user preferences reliably across cookies, IndexedDB, and localStorage
- protect browser storage from eviction under storage pressure
- replace evercookie-style persistent storage with a modern Promise API
- self-heal corrupted or deleted browser storage data

## When to choose
- you need highly persistent client-side key-value storage in the browser
- you want redundancy across multiple browser storage backends with automatic healing
- you want a simple Promise-based API using only standard HTML5 storage APIs

## When to avoid
- you need server-side or structured/relational storage
- you need to store non-string data types or large binary blobs
- you want storage that users can fully and easily purge, since redundancy makes deletion harder

## Facets
