LohnStudio

Swiss payroll — entirely on your device

Privacy policy

Last updated: 5 September 2026

LohnStudio calculates payroll under Swiss law — entirely on your own device. There is no server, no user account, no login and no network connection. We as the developer receive none of your data.

In short

LohnStudio collects no data. No servers, no user account, no login, no network connection. No analytics, no statistics, no advertising, no trackers, no crash reports to us. Everything you enter stays in a file inside the app’s folder on your device.

What data does the app process?

All information comes from you; the app collects nothing on its own. It processes:

• Company details: name, address, company ID, details of the compensation office and insurers, contribution rates.
• Employee details: name, address, date of birth, social security (AHV) number, IBAN, workload, start and end dates, marital status and withholding tax tariff data.
• Salary and absence data: salaries, allowances, expenses, deductions (AHV/IV/EO, ALV, BVG, UVG, KTG, withholding tax) as well as holiday, sickness and accident absences.

Social security number, date of birth, IBAN and salary figures are sensitive personal data. They are used solely to calculate and produce the payslip — never analysed, profiled or passed on.

Where it is stored: in a file inside the app’s protected folder on your device. We recommend protecting the device with a passcode and — on the Mac — with FileVault; that is the most effective protection for this file.

Where does this data go?

Nowhere.

The app opens no internet connection. There is no server of ours, no cloud sync and no interface to third parties. Your data leaves the device only when you hand it over yourself:

• when you export, print or send a payslip as PDF,
• when you export the accounting journal as CSV,
• when you generate an e-banking payment file and upload it to your bank portal.

What happens to such a file afterwards — e-mail, printer, cloud folder, bank — is entirely up to you. From that moment the privacy terms of the service you chose apply. Please do not send payslips unencrypted to open distribution lists.

Backups

If iCloud Backup (iOS) or Time Machine or another backup (macOS) is enabled on your device, LohnStudio’s data file may be included in that backup. This is a setting of your device, not a feature of the app — the app backs up nothing on its own, and we have no access to such a backup.

A backup is sensible: if the device is lost, so are the payroll records you must keep for ten years as an employer. If you nevertheless do not want it, disable the backup for LohnStudio in your system settings and instead keep your own regular copy in a safe place.

Your rights

Access, rectification, erasure, restriction, objection and data portability always have to be addressed to the party that processes the data. We hold no data from LohnStudio — so there is nothing to request from us, and we could not provide any information even if asked.

You exercise your rights directly in the app, at any time and without us:

• view all recorded data,
• change or correct it,
• export it as PDF or CSV — which is also your data portability,
• delete individual records, or everything by removing the app.

Step-by-step instructions are under “Delete data” at the top of this page.

Responsible for the data processing

LohnStudio is merely a local tool on your device for that purpose, comparable to a spreadsheet. We are neither a processor nor a recipient of this data, because it never reaches us. A data processing agreement is therefore unnecessary and would have no subject matter.

As the controller you are responsible in particular for:

• informing your employees which data you process and for what purpose;
• recording only as much data as payroll actually requires;
• adequately protecting the device and the exported files (device passcode, FileVault, no open distribution lists);
• keeping payroll records for ten years (Art. 958f Swiss CO) and answering your employees’ access requests yourself.

Responsible for the app itself — its provision, how it works and this policy — is:

Contact

We are happy to answer questions about the app, this policy or the calculations. Please do not include any payroll or employee data — we do not need it and do not want to receive it.
