1. Overview

This privacy policy informs you which personal data we process when you visit this website, for what purpose, and what rights you have.

Personal data is any information relating to an identified or identifiable natural person. “Processing” includes any handling of personal data, regardless of the means and procedures used — in particular collecting, storing, using, disclosing and destroying.

The Swiss Federal Act on Data Protection (DSG) and the Data Protection Ordinance (DSV) apply.

2. Controller and contact

The controller responsible for processing personal data on this website is:

Dr. TRETTER AG
Schaffhauserstrasse 96
8222 Beringen
Switzerland

Email: info@tretter.ch
Phone: +41 52 670 06 10

The controller is the person who, alone or jointly with others, decides on the purpose and means of processing.

3. Principles of our data processing

We process personal data in good faith, proportionately and transparently. We collect data only for a specific purpose that is apparent to you and do not process it in a way that would be incompatible with that purpose.

As a private company, we do not require a legal basis under Swiss law for processing. Where we obtain your consent for specific processing — for example for analytics services or the newsletter — this is expressly noted below. You can withdraw consent at any time with effect for the future; this does not affect the lawfulness of processing carried out up to that point.

We ensure the security of personal data with appropriate technical and organizational measures. We point out that data transmission on the internet, especially by email, may have security gaps and that complete protection against access by third parties is not possible.

4. Your rights

Under the DSG, you have the following rights in particular:

• Right of access: You can request information at any time as to whether we process personal data about you, and which data.
• Rectification: You can request that incorrect personal data be corrected.
• Deletion or destruction: You can request the deletion or destruction of your personal data, provided there are no statutory retention obligations or overriding interests to the contrary.
• Objection: You can object to specific processing.
• Data release and transfer: You can request that we provide you with personal data that you have disclosed to us in a common electronic format or transfer it to another controller.
• Withdrawal of consent: possible at any time, with effect for the future.

To exercise these rights, an informal notification to the address stated in section 2 is sufficient. We may request suitable evidence to verify your identity.

In addition, you may contact the Federal Data Protection and Information Commissioner (FDPIC), Feldeggweg 1, 3003 Bern.
