Swiss data protection and the GDPR
This is general information, not legal advice. Your legal adviser has the final word.
Revised FADP (nDSG)
The revised Federal Act on Data Protection came into force on 1 September 2023. We plan privacy by design, clear notices, data minimisation and deletion into the app from the first sprint.
Official source: Federal Office of Justice (bj.admin.ch) ↗FDPIC supervision
The Federal Data Protection and Information Commissioner (FDPIC) is the supervisory authority that makes sure federal bodies and private companies do not process personal data unlawfully.
Official source: FDPIC (edoeb.admin.ch) ↗GDPR for users across the border
If your app serves people in France, Germany or elsewhere in the EU, the GDPR applies too. We plan for both from the start.

Frequently asked questions
App development in Basel: before you book a call.
Do you have an office in Basel?
No. We serve Basel from our Zürich office at Hardstrasse 201, 8005 Zürich, about 70 km away. Meet us in person at our Zürich office or at any of our 10 offices, or by video. Workshops, design reviews and weekly check-ins run in English.
How much does app development cost in Basel?
Pricing is custom. Cost depends on platforms, screens and features, integrations, design depth, compliance needs and your timeline. After a short brief and a free 30-minute call, you get a written estimate.
How long does it take to build an app?
Typically: discovery 1 to 3 weeks, design 2 to 5 weeks, build 8 to 16 weeks for a first version, testing and store release 1 to 3 weeks. These are ranges, not guarantees.
Should we build a native app or use Flutter or React Native?
Native (Swift for iOS, Kotlin for Android) suits top performance and deep device features. Cross-platform (Flutter or React Native) shares one codebase and usually reaches both stores faster. We recommend one in discovery.
Can we meet in person?
Yes. Our nearest office is Zürich, about an hour from Basel. Meet us in person at our Zürich office or at any of our 10 offices, or by video.
How do you handle the revised Swiss FADP and the GDPR?
We plan privacy by design and by default, clear notices, data minimisation and deletion into the app from the first sprint, and the GDPR too when you serve users in the EU. Your legal adviser has the final word.
Do you build apps for pharma and life-science companies in Basel?
Yes, for example study, patient-support, field and internal apps. We document how data and access are handled so your quality and compliance teams can review it, and test security before every release.
Can the app work in German, French and English?
Yes. We set up the app for several languages from the start, so adding a language later is a content task, not a rebuild. German, French and English are among our eight working languages.
Who works on our project, and how do we communicate?
Projects are led by UnFoldMart from our international offices, with a small dedicated team; projects for Basel are led from our Zürich office. Calls are by video, in English, with a demo after each sprint.
Can you take over an existing app?
Yes. We start with a review of the code, the store listings and the backend, then fix, upgrade or rebuild in steps, so your app stays available.
