            The latest release is always accessible via our alias to the Cloudflare IPFS gateway at [app.uniswap.org](https://app.uniswap.org).

            You can also access the Uniswap Interface directly from an IPFS gateway.
            The Uniswap interface uses [`localStorage`](https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage) to store your settings.
            **Beware** that other sites you access via the _same_ IPFS gateway can read and modify your settings on the Uniswap interface without your permission.
            You can avoid this issue by using a subdomain IPFS gateway, or our alias to the latest release at [app.uniswap.org](https://app.uniswap.org).
