Many schools block the installation of new software. You cannot run the .exe or .dmg installer. However, you can use a Portable version of the DuckDuckGo browser.
You tried the methods above, but you still see a block page. Here is the diagnostic checklist:
The standard DuckDuckGo page runs heavy JavaScript. Network filters sometimes block pages based on JavaScript signatures. The lightweight HTML version has almost no scripts and is often miscategorized.
DuckDuckGo operates an official Tor hidden service. Even if your ISP or government has blocked every standard IP address associated with DuckDuckGo, the Tor network can route around the block.
Admins often use content filters like GoGuardian, Lightspeed, or Fortinet. These filters typically block categories like "Proxy Avoidance" or "Anonymizers." Since DuckDuckGo promises privacy (and allows !bang commands to redirect searches), overzealous filters sometimes flag the entire domain as a way to bypass monitoring. duckduckgo browser unblocked
If you are trying to use the actual DuckDuckGo Private Browser app on a phone or tablet but cannot find it in the app store (or it is restricted):
If you're accessing the internet through a network that blocks DuckDuckGo, try switching to a different network. For example, if you're at school or work, try accessing DuckDuckGo from your home network.
Proxy servers act as intermediaries between your device and the internet. By using a proxy server located in a region where DuckDuckGo is not blocked, you can access the search engine.
