Safety & Security

U Dictionary is a standard Android package. As with any APK, download it only from a trusted source and verify the file’s integrity if a hash is provided.

Keep the app updated to receive the latest security patches, and avoid entering sensitive personal information unless you are certain the app is legitimate.
