CleanboardCleaner

9 months on Pixel 3. Excellently simple and effective utility on Android 9 [Pie]. However, its operation appears not to have survived the upgrade to Android 10: No longer cleans the Clipboard and no longer provides the corresponding message, "Clipboard has been emptied'. Only notifies that that 'Clipboard is empty', which manifestly is NOT the case. Here's hoping compatibility with A10 can be be accomplished and a return to 5 Stars!

Works on Android v12 on my new Samsung S22 Ultra, despite the limitations described here under "About this app" (read below). It certainly cleans text (e.g. passwords) from the clipboard, which is crucial - and the only thing I use it for. I like apps that does one thing and one thing only (utilities) like this one. I know it's supposed to be able to show the content of the clipboard too, but I don't need, use or have tested that. Added the 5th star. 21 Sep 2022

I agree with the word "incompetent" in the app's own description. Don't be thinking that this app actually works unless you have the know-how to thoroughly check its effectiveness. The app may say your clipboard is clean but, as the dev says, it may actually not be. In my tests other apps can read the clipboard EVEN WHEN this app tells me it's clean. When the app says that it has cleaned the clipboard, it probably hasn't. Along with the developer I understand why not. Hopefully you do also.
