Under what circumstances can your personal data be transmitted to other entities, sub-contractors or third parties?

Your data can be transmitted to sub-contractors so that they can use them for and in the name of NOS. In this case, NOS will take the necessary contractual measures to ensure that subcontractors respect and protect the owner’s personal data.  
The data can also be transmitted to third parties – entities which are distinct from NOS or subcontractors – such as for example companies within the NOS group, companies with which NOS has built partnerships, where the owner has given his permission, targeted advertising service providers (for instance, social media) or entities to which data have been communicated due to legal requirements, such as the fiscal authorities.  

Regarding NOS’s personalized ads on third party platforms:

• How it works - When you use our websites and contacts, we collect information that allow us to personalize our ads based on your interests, either through their presentation or omission. These ads are displayed on NOS's digital platforms (apps and websites) and third parties (such as Google, Meta, and TikTok).
  The personalization of ads on third-party platforms involves sharing your data with these entities, which, in certain situations, may act as joint data controllers. On our websites, you can check on the information provided alongside those contacts, whether your data will be shared with third parties. If you do not wish for us to share this information, you can always use our alternative contacts.

• Data processed - To present you with ads, we may use your identification and contacts, along with service data and, if you have allowed cookies, your browsing data on websites and apps. You can check examples of data that fall under the categories mentioned here.

• Stop receiving - To stop receiving personalized ads on NOS's digital platforms, you can access the cookie settings panel of that platform and withdraw permission for "personalized advertising“. You can also deactivate marketing messages through your device's notification settings.
  To stop receiving personalized ads from NOS on third-party platforms, you can change your preferences regarding cookie settings and personalized ad presentation directly on those platforms. Please note that you may continue to receive non-personalized ads related to NOS. NOS is not responsible for any other type of personalized ads you may receive.

• More information - You can find complete and updated information about NOS's personal data processing in our privacy policy. For information regarding data processing on third-party digital platforms, please check the privacy policies of those entities.

Under what circumstances can NOS transfer your data to a third party?

NOS may have to transfer your personal data to a third party country outside the European Union and which is not part of the list of countries that the EU considers to have adequate levels of protection of personal data. Under these circumstances, NOS will ensure that any data transfers are done in strict compliance with applicable legal regulations.
