We use necessary cookies to ensure the functionality and security of our websites. This processing serves our legitimate interests in operating our websites. 

In addition to the so-called necessary cookies, Sunrise may use additional or optional cookies when you visit our website. Performance and functional cookies are used for this purpose. These cookies help Sunrise to improve your experience on our website and to customize it according to your needs as well as to conduct market research. At the same time, this simplifies the usage as you don’t need to enter certain information repeatedly (e.g. when logging in).

In this case, the data processing is carried out in connection with the fulfillment of pre-contractual or contractual obligations as well as in our legitimate interest. 

Please also note that when you use our services, the data protection provisions in the current General Terms and Conditions and other applicable contractual provisions apply in addition to this Privacy Notice.

If you choose an online payment option, such as credit card, to purchase a product or obtain a service, the payment will be made via the online payment system of the respective provider. Please note that when using online payment systems, the data protection provisions of the respective provider also apply. 
 
3.3 Apps 

We use your data to ensure that our apps work properly. This includes login data and information about the functions you use within the app. To fix bugs and malfunctions, we sometimes need to use personal data, for example to evaluate why an app is not working properly. During system checks, we keep our analyses as simple and short as possible and delete the data once it is no longer needed for bug fixes or improvements. 

This includes, for example, the following data:

3.4 Marketing and newsletters 

In connection with the provision of our services, we use your personal data for marketing purposes and newsletters.  

Customer marketing serves our legitimate interests in promoting and improving our services. Newsletter subscriptions are addressed separately below. Service-related communications are separate from marketing messages. We send marketing messages by email, SMS, telephone or post in accordance with the consent requirements applicable to each channel. You can withdraw your consent or object to marketing at any time through your customer account, where available, or by contacting us. You can also unsubscribe from marketing emails using the link provided. This does not affect essential service-related communications. 

If you subscribe to a newsletter, we use your email address to send you the communications described when you subscribe. You may withdraw your consent at any time using the unsubscribe link in each newsletter. 

We use service providers to distribute newsletters and share your email address with them for this purpose. You can unsubscribe at any time using the link in each newsletter. 
 
3.5 Raffles and contests 

Personal data is processed in accordance with applicable legal provisions. Data collected for a raffle or contest will be used exclusively to conduct it, determine the winners and award prizes, unless you consent to broader use of your personal data. 

The applicable participation terms also apply. 
 
3.6 Credit checks 

If you wish to conclude a contract with us, we are entitled to carry out a credit check before concluding the contract. For this purpose, we may consult debt collection agencies (in particular Intrum AG, based in Schwerzenbach). We also use our own information about your previous payment history. We use this information to assess your creditworthiness. The credit check is a partially automated process that helps us decide whether, to what extent and under what conditions we can conclude the contract you have requested. We also transmit data about conduct contrary to contractual obligations or fraudulent behavior to the aforementioned third parties. This processing is carried out in connection with the conclusion of the contract. 
 
3.7 Contact requests 

You can send support or other service-related requests at any time via helpdesk, chat or via Sunrise Community. 

The mandatory fields in the contact form or Sunrise Community include your user login data (email address, telephone number or customer number), the support topic and your message (including any uploaded files). 

This information is required to process your request and provide any feedback. We also use AI to analyze chat histories, uploaded files and customer-service conversations to understand requests and improve service quality. Personal data used for this analysis is processed in Sweden. Further information is provided in Section 7 ‘Use of artificial intelligence (AI)’ and Section 9 ‘Data transfers abroad’. 
 
3.8 Social media 

Our websites provide access to our social-media profiles through the respective platform logos. 

The data protection provisions of the respective platform provider apply, whereby some content may only be accessible if you have a corresponding user account on the platform. 

When you follow a link to a social-media platform, it processes personal data in accordance with its own privacy notice. If you are logged in to that platform, it may associate your visit with your account. Logging out does not necessarily prevent the platform from receiving technical information.  

3.9 Visiting our shops 

For your and our safety, our shops are monitored by video. This video monitoring is intended to protect against theft, vandalism, assaults and burglary. It helps us ensure a safe environment for our customers and employees. The recording is carried out in accordance with applicable Swiss laws governing data and privacy protection. The recordings are stored for a maximum duration of 20 days and are shared with the relevant authorities only upon request in the event of a police investigation. 

4. Protection of your personal data

Sunrise has implemented numerous technical and organizational measures to protect your data from unauthorized or unlawful processing and from loss, alteration, misuse, destruction or unauthorized access.

5. Duration of data storage

We retain personal data for as long as necessary for the purposes described in this Privacy Notice, including to meet applicable retention obligations and establish, exercise or defend legal claims. We then delete or anonymize it.

Location data retained to meet statutory telecommunications obligations is stored for six months and then deleted, subject to any applicable preservation requirements. Where we use location data for other purposes, including to measure and improve network quality, we retain it only for as long as necessary for the relevant purpose and then delete or anonymize it. Wherever possible, we use anonymized or aggregated data for network-quality analysis.

Usage data is only stored for as long as it is required for the fulfillment of the contract or our legitimate interests and then deleted.

This is subject to legal retention periods and the use of data to enforce legal claims.

6. Data transfer to third parties

In order to be able to offer you our website and services, we involve third parties. These are primarily service providers, such as our cloud providers. Due to legal and/or regulatory requirements, we may also be obliged to disclose data to competent courts, authorities, or other government bodies. In addition, we pass on your location data to the responsible emergency call center if you make an emergency call from your smartphone.

We work particularly closely with some partners, for example in customer service (call center) or with IT service providers. Before these partners are allowed to process your personal data on our behalf, we contractually ensure that they comply with the applicable data protection laws and implement the necessary technical and organizational measures to protect your data.

We may share personal data with other companies in the Sunrise group to the extent covered by the purposes described in this Privacy Notice.

7. Use of Artificial Intelligence (AI)

Sunrise uses artificial intelligence (AI) to analyze data, optimize its networks, personalize services and offers, detect and prevent fraud, improve its products and customer support, and operate virtual assistants and chatbots. When you interact with an AI-based virtual assistant or chatbot, we make this clear to you. 

We process personal data in connection with AI only for specified purposes that are recognizable to you, in accordance with applicable data protection law and our internal AI governance framework. Our safeguards include clearly assigned responsibilities, transparency and, where appropriate, explainability, human oversight, testing and monitoring, information security, and privacy by design and by default. These measures serve to protect personal data and to reduce the risk of bias, misuse and unintended consequences. 

Content generated by AI, such as responses from our virtual assistants and chatbots, may be inaccurate, incomplete, misleading or outdated, and we cannot guarantee its correctness. Please verify important information and exercise your own judgment before relying on it.  

7.1 Automated individual decisions 

Automated individual decisions may involve AI or other automated processing. We do not make decisions based exclusively on automated processing that have legal effects on you or significantly affect you, unless this is permitted by applicable law and appropriate safeguards are in place. When we make such a decision, we will inform you accordingly. Where required by applicable law, you may express your point of view and request review by a member of our staff.  

Where AI supports a decision made by our staff, the decision remains subject to human oversight. Where we make decisions exclusively by automated means, the safeguards described in Section 7.1 apply. 

8. Personalized prices and offers

We use AI-supported mechanisms to adapt certain prices and offers to you individually. For this purpose, we evaluate personal data from your customer profile, in particular the products and services held on your account, including tariffs, options, devices and existing discounts; information about your customer relationship, such as contract duration and tenure; and financial information relating to those products and services, such as recurring charges and revenues. We may also use telecommunications usage information to estimate the costs and value associated with the customer relationship. 

We do not use sensitive personal data to personalize prices or offers. The pricing engine used to determine personalized prices and offers does not use precise location data.  

We design and regularly review these mechanisms to prevent unlawful discrimination. 

If your personalized price is determined exclusively by automated means, you may express your point of view and request a review by a member of our staff. 

9. Data transfers abroad

While providing its services, Sunrise also relies on products and services from producers and suppliers abroad who process Data or telecommunications data on behalf of Sunrise in the course of fulfilling their obligations, for example when providing maintenance or service support (including call centers). 

Your data will always be treated with the necessary care and processed in compliance with the applicable data protection regulations. Your data will be processed within the European Union, the European Economic Area (EEA), Moldova, India, Tunesia, Georgia, Kosovo, Serbia, Turkey, the United States, the United Kingdom and Switzerland. 

Where personal data is transferred to a country that provides a different level of data protection, an adequate level of data protection is ensured through contractual measures, such as standard contractual clauses, together with supplementary technical and organizational measures where necessary.
