If Exodus as a company dies (HIGHLY unlikely at this point), the Exodus app will still open on your computer. The exchange feature won't work, obviously. Some assets won't be able to send due to our servers being down (some will fallback to public servers and still work). For those assets that don't work, you can either import your Exodus 12 words into a compatible wallet to claim them, or export private keys from your Exodus app and import each private key one-by-one into a wallet for that asset.
