What you can reach out about
Bug reports & errors
Found a calculator that returns a wrong result? A broken tool? A PDF that didn't convert correctly? These are the most valuable messages — please send them.
Tool suggestions
Need a calculator, converter, PDF tool, generator, or developer utility that isn't here yet? Suggest it. If it's useful and fits the site, I'll build it.
Formula or data corrections
Spotted a formula that doesn't seem right, or data that looks outdated? I genuinely appreciate these — corrections like these make the tools better for everyone.
General feedback
Something you like, something you hate, a UX complaint, or just a general thought about the site. All feedback is welcome and helps shape where the project goes next.
Support the project
Like the tools? Buy me a coffee.
Nivesly Tools is free and will stay free. If these tools have saved you time, you can optionally support the work behind them. It goes directly toward hosting costs and building more tools.
