support@nettopia.appHow accurate are the results?
Nettopia implements each country's official rules – wage tax, surcharges and all social security contributions – and is checked with 121 reference cases against the finance ministries' official calculators. Results are still non-binding estimates: your payslip is what counts.
Which countries are supported?
Currently Germany and Austria – more countries are coming. New values and laws arrive automatically, no app update needed.
Is my data stored or transmitted?
No. All inputs stay on your device. The app only downloads a public file with current contribution rates and tax values. Only if you choose to turn on notifications is an anonymous device token registered with Google Firebase. Details in the privacy policy.
What does Nettopia cost?
Nothing. Nettopia is free and has no ads.
Which languages are available?
German and English. The app follows your device, but you can switch under “More”.
How do I restart the tour?
In the app under “More → App tour”.
