1. Introduction
In this Privacy Policy, we, tiun AG (also "we", "us"), describe what we do with your data when you use our website, communicate with us or otherwise deal with us. In addition, we may inform you about the processing of your data separately.
If you disclose data to us or share data with us about other individuals, such as family members, co-workers, etc., we assume that you are authorized to do so and that the relevant data is accurate. When you share data about others with us, you confirm that. Please make sure that these individuals have been informed about this Privacy Policy.
This Privacy Policy is aligned with the EU General Data Protection Regulation (GDPR) and the Swiss Data Protection Act (DPA). However, the application of these laws depends on each individual case.
This Privacy Policy is not part of a contract with you. We can change this Privacy Policy at any time. The version published on this website is the current version.

3. Collection and Processing of Personal Data
We primarily process personal data that we obtain from you when you communicate with us or that we collect from users when operating our website.
Insofar as it is permitted to us, we obtain certain personal data from certain parties, e.g. in connection with your use of our website (e.g., IP address, information regarding your device and settings, cookies, date and time of your visit, sites and content retrieved, referring website, localization data).
4. Purpose of Data Processing and Legal Grounds
In relation to our website, we may process your personal data and personal data of third parties for the following purposes, which are in our (or, as the case may be, any third parties') legitimate interest, such as:
providing and developing our website;
advertisement and marketing (including organizing events), provided that you have not objected to the use of your data for this purpose (if you are part of our customer base and you receive our advertisement, you may object at any time and we will place you on a blacklist against further advertising mailings);
market and opinion research, media surveillance;
asserting legal claims and defense in legal disputes and official proceedings;
ensuring our operation, including our IT and our website.
If you have given us your consent to process your personal data for certain purposes (for example when registering to receive newsletters), we will process your personal data within the scope of and based on this consent, unless we have another legal basis, provided that we require one. Consent given can be withdrawn at any time, but this does not affect data processed prior to withdrawal.
5. Cookies
We typically use "cookies" and similar techniques on our website, which allow for an identification of your browser or device. A cookie is a small text file that is sent to your computer and automatically saved by the web browser on your computer or mobile device, when you visit our website. If you revisit our website, we may recognize you, even if we do not know your identity. Besides cookies that are only used during a session and deleted after your visit of the website ("session cookies"), we may use cookies in order to save user configurations and other information for a certain time period (e.g., two years) ("permanent cookies"). However, depending on the purpose of these technologies, we may ask for consent before they are used. Notwithstanding the foregoing, you may configure your browser settings in a way that it rejects cookies, only saves them for one session or deletes them prematurely. Most browsers are preset to accept cookies. We use permanent cookies in order to understand how you use our website. Certain cookies are sent to you from us, others from business partners with which we collaborate. If you block cookies, it is possible that certain functions are no longer available to you.
We currently use offers from the following service providers:
We use the feature experimentation and analytics service Statsig, provided by Statsig, Inc., 1065 Borregas Ave, Sunnyvale, CA 94089, USA. Statsig allows us to test and gradually roll out product features and better understand how users interact with our website and services. The insights gained help us improve our offerings continuously. Statsig processes pseudonymized user data such as event logs, feature exposure, usage patterns, IP address, and technical information like browser and device type. Statsig typically uses cookies or similar technologies for this purpose. The processing of data is based on your consent. You can withdraw your consent at any time with effect for the future. Statsig is based in the United States. An adequate level of data protection for transfers of personal data outside the EU/EEA or Switzerland is ensured through the use of Standard Contractual Clauses (SCCs). Further information about Statsig’s data protection practices is available here
6. Data Transfer and Transfer of Data Abroad
In the context of our business activities and in line with the purposes of the data processing set out in Section 4, we may transfer data to third parties, insofar as such a transfer is permitted and we deem it appropriate, in order for them to process data for us or, as the case may be, their own purposes. In particular, the following recipients set out in Section 5 may be concerned. Additionally, we may disclose personal data to courts and other authorities in Switzerland and abroad if we are legally obliged or entitled to make such disclosures or if it appears necessary to protect our interests. Finally, in certain circumstances we may interact with third parties where such interaction follows from the purposes set out in Section 4.
Certain Recipients may be within Switzerland but they may be located in any country worldwide. You must anticipate your data to be transmitted to any country in Europe and the USA where our service providers are located.
If a recipient is located in a country without adequate statutory data protection, we require the recipient to undertake to comply with data protection (for this purpose, we use the revised European Commission’s standard contractual clauses, which can be accessed here), unless the recipient is subject to a legally accepted set of rules to ensure data protection and unless we cannot rely on an exception. An exception may apply for example in case of legal proceedings abroad, but also in cases of overriding public interest or if the performance of a contract requires disclosure, if you have consented or if data has been made available generally by you and you have not objected against the processing.
7. Retention Periods for Your Personal Data
We process and retain your personal data as long as required for the performance of our contractual obligation and compliance with legal obligations or other purposes pursued with the processing. Personal data may be retained for the period during which claims can be asserted against our company or insofar as we are otherwise legally obliged to do so or if legitimate business interests require further retention (e.g., for evidence and documentation purposes). As soon as your personal data are no longer required for the above-mentioned purposes, they will be deleted or anonymized, to the extent possible. In general, shorter retention periods of no more than twelve months apply for operational data (e.g., system logs).9. Contact Us
If you have any questions about this Privacy Policy or our data practices, please contact us at our email address.
8. Data Security
We take appropriate security measures in order to maintain the required security of your personal data and ensure its confidentiality, integrity and availability, and to protect it against unauthorized or unlawful processing, and to mitigate the risk of loss, accidental alteration, unauthorized disclosure or access.
9. Your Rights
In accordance with and as far as provided by applicable law (as is the case where the GDPR is applicable), you have the right to access, rectification and erasure of your personal data, the right to restriction of processing or to object to our data processing, in particular for direct marketing purposes and for other legitimate interests in processing in addition to right to receive certain personal data for transfer to another controller (data portability). Please note, however, that we reserve the right to enforce statutory restrictions on our part, for example if we are obliged to retain or process certain data, have an overriding interest (insofar as we may invoke such interests) or need the data for asserting claims. If exercising certain rights will incur costs on you, we will notify you thereof in advance. We have already informed you of the possibility to withdraw consent in Section 4 above.
In general, exercising these rights requires that you are able to prove your identity (e.g. by a copy of identification documents where your identity is not evident otherwise or can be verified in another way). In order to assert these rights, please contact us at the addresses provided in Section 2 above.
In addition, every data subject has the right to enforce his/her rights in court or to lodge a complaint with the competent data protection authority. The competent data protection authority of Switzerland is the Federal Data Protection and Information Commissioner.
