We compared the signing certificate of this build with the certificate recorded the first time it.collideorscopeapps.codename_hippopotamos 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 no permissions at all.
Its licence is CC-BY-SA-4.0. We took this build from F-Droid, and the source for this exact version is linked below.
The most recent release upstream is from Jan 10, 2020, over 6 years ago. It still installs; it is simply not being updated.
We do not show a star rating or an install count for this page: we have no measured figure for either, and a number we cannot source is worth less than an empty field.
