Swiss data protection in a nutshell

POSTARMAIL has everything you need to get your and your clients' personal and business communications up and running in no time!
All with the ease and security of our Swiss-based infrastructure, under the protection of some of the toughest data protection and privacy guarantees in the world.

The law

The Data Protection Act (DPA) guarantees that all personal data can only be processed lawfully. All personal data processing must also be proportionate and carried out with the best intentions. Article 13 of the Swiss Federal Constitution guarantees your right to privacy. Since 1993, the Federal Act on Data Protection and security has prohibited the processing of personal data without the explicit authorization of the data subjects.

The country

Switzerland is a world leader in banking, finance and international trading with a longstanding tradition of security and confidentiality. With an industry-leading IT infrastructure and data protection ingrained in Swiss law, Switzerland is the ‘secure heart of Europe.’ Due to its political stability, Switzerland is considered one of the safest countries in the world. Before deciding where to store your data, we considered stability as a key factor.

The people

The Swiss are rightfully viewed as representing the values of stability, neutrality, discretion and trustworthiness. The Swiss are a multilingual people, with four national languages spoken including German, French, Italian and Romansh. English is also widely spoken, with most companies speaking English in business. Language barriers are not a problem when working with and safeguarding your valuable data in Switzerland.
