To help you navigate the maze of privacy policies as easily as possible, this Privacy Policy is divided into two sections: the first section covers only the essentials (1–10), followed by more detailed information in the second (11–17).
Here, we explain how we collect personal data via this platform and other online channels, or process it in other ways. Personal data refers to any information relating to an identified or identifiable individual.
Please feel free to contact us directly at any time if this information does not answer all your questions.
The data controller within the meaning of data protection law is:
Institute for Swiss and International Tax Law (ISIS) Office Seestrasse 344 CH-8038 Zurich hello@zsis.ch +41 44 533 17 88
We process your personal data primarily for the following purposes:
We process the following types of personal data:
The legal basis for processing your personal data is typically:
If personal data is processed by external processors, we ensure that legal requirements are met. Disclosure to third parties generally only occurs if it is necessary for the performance of the contract with you, if disclosure is permissible based on a balancing of interests, if we are legally obligated to disclose the data, or if you have given your consent in this regard. Your data will never be sold.
Regular recipients of personal data may fall into the following categories:
Personal data is transferred to the specified recipients abroad within the scope of the processing described in this Privacy Policy. This applies to service providers whose servers or headquarters are located outside Switzerland (e.g., in the EU or the U.S.).
If data is transferred to countries without an adequate level of data protection, we ensure through appropriate safeguards that your personal data is adequately protected to the extent required by law.
We process personal data only for as long as necessary for the respective purpose.
If we store the data based on a contractual relationship with you, this data will remain stored at least as long as the contractual relationship exists and, at the latest, until the statute of limitations for potential claims by or against us expires or statutory or contractual retention obligations apply.
You have the right to access the personal data we process about you. Provided the legal requirements are met, you are also free to request data portability, rectification, erasure, or restriction of processing.
We ask for your understanding that, in such cases, we may require proof of identity to ensure that you are the person you claim to be.
You are also free to withdraw your consent to the processing of your personal data at any time. Within the framework of legal requirements, you also have the right to object to certain processing activities, for example, if they are based on a balancing of interests. In particular, you have the right to object to the processing of your data in connection with direct marketing.
The withdrawal of consent does not affect the lawfulness of processing carried out prior to the withdrawal. However, withdrawal may result in certain services or functions of the platform no longer being available or only being available to a limited extent.
Please contact hello@zsis.ch for this purpose, as well as for any questions, suggestions, or requests.
You have the right to lodge a complaint with a data protection supervisory authority regarding our processing of your data. The supervisory authority responsible for private individuals in Switzerland is the Federal Data Protection and Information Commissioner (FDPIC) (Feldeggweg 1, 3003 Bern, Switzerland).
We implement technical and organizational security measures to protect your personal data against manipulation, loss, destruction, or unauthorized access. The measures taken are intended to ensure the confidentiality and integrity of your personal data, as well as the availability and resilience of our systems and services when processing your personal data on an ongoing basis. Furthermore, they ensure the rapid restoration of the availability of your personal data and access to it in the event of a physical or technical incident.
Our security measures are continuously improved in line with technological developments.
Our website may contain links to third-party websites to which this Privacy Policy does not apply. Once you click on the link, we no longer have any influence over the processing of any data transmitted to third parties (such as the IP address or URL), as the conduct of third parties is, by nature, beyond our control. We therefore cannot assume any responsibility for the processing of your personal data by third parties. To the extent that the use of other providers’ websites involves the collection, processing, or use of your personal data, please refer to the privacy policies of the respective providers.
