Is Duolingo Max safe?

Low risk

Duolingo Max modifies Duolingo pages to unlock paid subscription features and bypass feature gates.

On Duolingo pages, the extension injects scripts that intercept Duolingo app bundles and rewrites them before they run. The patched code makes the page show a paid subscription state, enables Plus-related flags, and routes premium practice buttons directly to the relevant Duolingo pages.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
