I use UPX packer, because I don't think it makes any sense to waste bandwidth and user resources by not compressing one's data. It's a matter of providing optimized binary file. I don't know what could cause high entropy, as I don't use any methods of obfuscation in the code. Here is the executable file without the UPX compression:
https://uninstalr.com/Uninstalr_v11_raw.exe
I specify in the Privacy Policy what information the program collects from users: None. (You can find the Privacy Policy at the bottom of the website
Uninstalr)
The only internet related thing that the program does is it checks for latest version if you click the "click here to check what is latest version" link at the bottom part of the UI, OR if you click the logo that opens the app's website. If you don't click either of those parts of the UI, the program doesn't connect to the internet at all and when it does connect, the only data it sends out is the app's name and version number as a part of the http agent string.
The method I use to fetch the latest program version is to use Windows API call InternetOpen(), InternetConnect() and HttpOpenRequest() to perform a http GET call to read the latest version number from the web server. That's all. If any of those function calls are somehow suspect, please let me know which Windows API calls should rather be used.
Not even the website uses any kind of Google or Facebook spyware. It doesn't even use any kind of tracking cookies. I would say my software including the website are among the most privacy friendly things you can find online.
And what it is worth: I have been publishing software since 1998. The number of malware that has ever been included in any file that I have ever published since that time is zero. I have not even include any gray area things, such as bundled software. Believe me, I get contacted on regular basis by some shady people asking whether I would be interested to include some VPN or browser extension to my software as a bundled software to be paid per install. I have said no to every single such offer since day one.
