You should hire a web designer to help you out a bit.

If you can't afford that, you could do the following small tweaks to make the site look better:

1. The main font color should be black or very dark gray, not this odd blueish green.
2. Get someone design you a logo. "MAJ" with the "A" awkwardly positioned does not look great. You can get a logo designed for you for a couple bucks at Fiverr or similar websites.
3. Use different color for the buttons. Now you have clickable elements (buttons) and non clickable elements (e.g. the top navigation bar) that look basically identical. This is bad for usability, when users need to be guessing what is clickable and what is not.
4. There is no need to have 10 CTA buttons in the front page. 1-3 CTA buttons would be enough.
5. Right now, the website as well as the UI of your web app is visually dull. An easy way to fix this would be to add some colorful icons. You can buy professional looking icons at 1-2 usd for one, or use some free icons collections.

There are also some bugs in the website. For example, there is no input validation in the signup form. One could even click the Create button without making any inputs at all.

Looking at the demo account, the web app itself looks pretty useful, if I'm being honest. If you invested into making the UI look really nice and fun to use, this could be a cool product!

I understand your point, but maybe you should go make that point with something else, that is actually suspect in regards of privacy.

This is open source, no data is sent anywhere, there is a clear privacy policy in place in the website, the author of the website is clearly indicated and it doesn't even use any adtech tracking spyware for website statistics. Literally everything about this website is made with privacy first.

It's literally open source. If you don't trust it, you can review it. Unlike most things people run on their computers.

If by honeypot you mean to imply that this website would collect some data: It doesn't. All data processing is done in the user's own browser and anyone can confirm this to be the case by analyzing the JavaScript of the page. This is also clearly stated in the website.

That just made Array Cat feel sad.

Just like cats.
