We compared the signing certificate of this build with the certificate recorded the first time io.github.sds100.keymapper.inputmethod.latin entered the site, and published both the file's SHA-256 and the certificate's fingerprint above so you can check the download yourself. That comparison says the file was not repackaged by someone else; it is not a review of what the app does.
The manifest inside the APK declares 5 permissions, none of which cover contacts, location, SMS, the camera or the microphone.
