How can I delete my MetaMask?
Due to the nature of the blockchain, you cannot permanently delete an account on the Ethereum network. You can "hide" any accounts you don't wish to see anymore by following the steps here.
If you no longer want to use MetaMask, simply uninstall.
Your ETH addresses are permanent on the blockchain and can simply be forgotten or abandoned if you like.
MetaMask is software that you can delete at any time. The accounts that you manage in MetaMask are permanent, and, once created, will be around for as long as Ethereum is. See also: What's the difference between a wallet and an account?

If you'd like to remove MetaMask from your browser, just open your browser extensions, click the 3 dots next to MetaMask, and click "Remove from Chrome" (this process will be similar for all web browsers).
On mobile, simply remove the app as you would any other, and according to how you normally would on your device.
