Ultrasurf is a modified‑free release, but as with any third‑party APK, download it from a reputable source. Review the permissions it requests; typical VPN apps need network access and the ability to create a VPN connection. Avoid entering sensitive credentials (banking, passwords) while using any unofficial build.
Because the app is free and does not require a subscription, updates may be less frequent. An updated version could change the server list or introduce new privacy policies, so keep an eye on release notes when a newer build appears.
