Hey everyone,
I wanted to share a project I launched this week: Calculy.online.
The idea stemmed from a real pain point: most payroll calculators today are slow, full of intrusive ads, and often ask for email/registration just to show a simple result.
The Technical Solution: I decided to go against the grain and create a PWA focused on performance and privacy.
Zero Backend: All calculation logic (progressive income tax, social security, vacation pay) runs in the user's browser via pure JavaScript.
Privacy: Since there's no server-side, salary data never leaves the user's device.
Stack: Semantic HTML5 + CSS3 (Grid/Flexbox) + Vanilla JS.
Hosting: Static.
The site already has 10 tools (Termination, Net Pay, Vacation, etc.).
I would greatly appreciate any feedback on the mobile UX or any bugs in the logic!
