Running a Snowflake Proxy is one of the easiest, safest, and most impactful ways to help people circumvent censorship, especially if you're in a place with an open and free Internet. Your device, through your public IP address, becomes an essential bridge for people in places where Tor is blocked (in, say, Iran or China) and an entry point to the Tor network. There are many ways you can run a Snowflake Proxy.
You are not using Tor yourself; you are simply a bridge for someone else.
All of the data passing through your device is encrypted; nothing is visible to you.
There will be an impact on your bandwidth, but it is minimal, and you can set limits.
Run Snowflake from a trusted, unrestricted, unlimited network.
When you can, set limits on when and how the Snowflake Proxy should be available.
Don't use it on shared, public, or corporate networks where administrators might block or misinterpret traffic.
