Privacy and data protection
Your tax data stays on your device. We take your privacy very seriously.
Your tax data stays on your device
Our calculator works entirely in your browser. Your personal and tax information is NEVER sent to our servers. You keep full control of your sensitive data.
What we collect
Our service is designed to minimise data collection as much as possible:
- Personal tax data: None. Your payslips and tax information stay on your device.
- Anonymous statistics: We collect anonymised usage data (number of visitors, pages viewed) only to improve the service.
- Cookies: Only for language preference and anonymous statistics. No advertising or tracking cookies.
How it works technically
Our calculator uses client-side processing technology:
You enter your data
The information from your salary certificate stays in your browser and is never sent to our servers.
Local calculation of your estimate
The tax calculation is done entirely in your browser. No data is transmitted online.
Result and recommendation
The estimate is done entirely in your browser. If you choose our TOU service (CHF 20), your data is transmitted securely only for filing the request.
Swiss compliance
We comply with all Swiss data protection standards:
- Compliant with the revised Swiss Federal Act on Data Protection (FADP) 2023
- Hosted in Switzerland (Swiss servers)
- No transfer of personal data outside Switzerland
- Full transparency on data processing and non-collection
Your rights
Since we do NOT store ANY personal tax data, there is nothing to delete, correct or export on the server side. You have full control because everything stays on your device. If you clear your browser cookies or close the tab, all traces of your calculations disappear from your device.
