Snowflake Volunteer is a tool that allows users to help people in restrictive regions access the uncensored internet by donating a portion of their own connection. It is an open-source Android application developed by the Tor Project in collaboration with Bloco that functions as a bridge to the Tor network.
According to the Tor Project, millions of users across the globe face government-imposed internet censorship that blocks standard access to privacy tools like the Tor Browser. By installing Snowflake, you act as a proxy, allowing someone whose access to the Tor network has been blocked to route their traffic through your connection, effectively masking their activity as standard WebRTC video traffic.
Snowflake bypasses censorship by disguising Tor traffic as common, unrestricted web activity. Many governments block access to the public directory of Tor relay nodes to prevent citizens from using the network. Snowflake circumvents this by using the WebRTC protocol, which is the same technology used for browser-based video conferencing and voice calls. Because WebRTC traffic is essential for modern business and communication, it is rarely blocked by censors. When a user in a restricted region connects to your device, their traffic appears to local censors as a standard, encrypted video call, preventing the government from identifying that the user is actually accessing the Tor network.
Volunteering your connection creates a decentralized and highly resilient network that is nearly impossible for censors to dismantle. Because Snowflake bridges are transient and constantly changing, censors would have to block vast swaths of legitimate video-conferencing traffic to stop the service, which would cause significant economic and social disruption. By acting as a volunteer, you provide a temporary gateway that allows someone else to reach the open internet. This peer-to-peer approach ensures that even if one bridge is discovered and blocked, thousands of others remain active, keeping the network alive for those who need it most.

More from GroundworkThe setup process for Snowflake Volunteer is designed to be minimal, requiring only a few minutes to configure on an Android device. Before you begin, ensure you have a stable internet connection—preferably Wi-Fi—to avoid unexpected data charges, as you will be relaying traffic for others.
- Download the application: Install the Snowflake Volunteer app from the Google Play Store or F-Droid to ensure you are getting the official, verified version.
- Adjust battery optimization: Open the app and follow the prompts to exempt it from your device's battery management settings. This ensures the app can continue running in the background without being shut down by your phone's power-saving features.
- Enable the service: Toggle the switch on the main screen to start the service. Once active, your phone will begin accepting connections from users in restricted regions.
- Monitor your status: The app interface will show you when someone is actively using your connection to browse the web. You can toggle the switch off at any time if you need to preserve battery or bandwidth.
Running Snowflake Volunteer is generally considered safe for the volunteer, as you do not see the traffic passing through your device, and the users are not accessing the internet through your personal identity. The traffic is encrypted end-to-end, meaning you cannot see what the person is browsing, and they cannot see your personal data. However, be aware that you are donating a portion of your bandwidth, which may impact your upload and download speeds. Always ensure you are on an unlimited data plan if you intend to leave the app running for extended periods, as the relaying process consumes data just like any other internet activity.
