What you keep in Space is not confined solely to our platform, as you retain ownership and control over your space, allowing access through various interfaces if desired. All files, transactions, and activities within Space benefit from end-to-end encryption, ensuring that only users hold the decryption keys necessary for access. Our code is open to anyone who wishes to review it, enabling verification of our privacy and security assertions, while developers are encouraged to build upon our Open Web framework. By utilizing a Space, you can securely store files that are exclusively under your control and accessibility. The management of your files and account keys resides solely with you, not us, and all data is automatically backed up to Filecoin, providing an additional decentralized layer of security. Each account in Space is linked to an Ethereum key-pair that only you possess and control. You have the option to log in using various methods, including Twitter, Gmail, or email secured through the Torus network, as well as high-privacy alternatives such as MetaMask and other cryptocurrency wallets. Additionally, you can share your content via convenient methods (like email or social media handles) or prioritize privacy with options such as crypto addresses and links, ensuring you can choose how to manage and distribute your data securely. Ultimately, the framework we provide empowers users to maintain autonomy over their digital assets and interactions.
