Public blockchains like Ethereum are the next evolution of Internet databases, and MetaMask is the next evolution of the browser.
MetaMask is a web browser extension and mobile app that allows you to manage your Ethereum private keys. By doing so, it serves as a wallet for Ether and other tokens, and allows you to interact with decentralized applications, or dapps. Unlike some wallets, MetaMask keeps no information on you: not your email address, not your password, and not your Secret Recovery Phrase or other private keys. You retain all power over your crypto-identity.

Configuring your privacy settings
When installing the MetaMask extension, you'll be able to adjust privacy settings one-by-one to ensure the app is set up according to your privacy preferences.
To do this, simply hit the 'Advanced configuration' button in the wallet set-up process. Here you can toggle/configure settings including:
* Phishing detection
* Incoming transactions
* Additional token price information from third-party sources
* The default RPC provider
* Token autodetect
* Batch account requests
* Custom IPFS gateway.
