Privacy Policy

Last Updated: June 9, 2023

Tredio is committed to protecting your privacy and treating your personal information with transparency, care, and respect.

This Privacy Policy (Policy) explains how we collect, use, and share (collectively, Access) your personal information, personal data, or the equivalent terminology in your region (collectively, Data). For reference, Data refers to any information that may directly or indirectly identify you. The Policy also explains how you can exercise your rights under applicable data protection and privacy laws, including data protection and privacy laws in California, Europe, and Brazil.

Any reference in this Policy to “Tredio”, “we”, or “our” refers to Coresibo Ltd. dba Tredio., and its direct and indirect global subsidiaries.


Tredio is a global digital advertising platform. Our technology (the Tredio player and exchange) helps our clients deliver advertising to you. The Tredio Platform hosts digital auctions that help our clients buy and sell online ads (collectively, our Platform Services). These ads can be found on websites, mobile applications (apps), or video programming services, such as streaming apps on Smart TVs (collectively, Digital Properties).

As with any exchange platform, we act as an intermediary between buyers and sellers. Throughout this Policy, we refer to our clients that sell ad space as Publishers. Publishers own or operate the Digital Properties you may use or visit. We refer to clients that buy ad space (e.g., advertisers) as Buyers. Buyers may include Demand-Side Platforms (DSP), Data Management Platforms (DMPs) and other partners (collectively, Demand-Side Partners). Demand-Side Partners act as additional intermediaries in the digital advertising supply chain that connect advertisers to Tredio to serve relevant ads to you on the Publisher Digital Properties you visit. Demand-Side Partners liaise with other Buyers, which also include advertisers (e.g., brands), advertising agencies, and ad networks (collectively, Ad Partners). In summary, Tredio and Demand-Side Partners act as intermediaries that connect Ad Partners with Publishers to deliver relevant digital ads to you.

This Policy describes Tredio’s Data practices. It does not apply to information or Data collected by third parties, including those of Publishers or Buyers. We recommend that you consult the privacy policies of the Digital Properties you use in order to become familiar with their privacy practices.

Please note, Sections 1-10 of this Policy provide information about the Data we Access in the provision of our Platform Services to our clients. For information on our corporate Data collection practices, please refer to our Corporate and Careers Privacy Policy under Section 11.

We recommend that you read this Policy in full.


Tredio may Access your Data in different ways depending on the way you interact with us. Please find below an overview of how we may Access your Data.

Platform Services: Tredio Accesses your Data when you visit a Publisher’s Digital Properties. Tredio Accesses your Data only to provide our Platform Services if we have permission from Publishers to do so. The Data we Access is limited to digital identifiers (e.g., cookies, device information, IP address).

Corporate: If you interact with us in a business capacity, we Access your Data as part of our business relationship with you, either pursuant to a written agreement, or because of our legitimate interest.

Website: If you accept cookies, when you visit our corporate website, or any international, affiliated Tredio websites (Website(s)), Tredio receives Data including your IP address and information about your browsing behavior on our Website(s). If you fill out a form to connect with Tredio over email (for example, to hear more about our products and services), we collect and store your name and email and use this Data to communicate with you for the express purpose described when you provided this Data; we also associate this Data to the Data Tredio previously received from the cookies on our Website(s) (noted in the previous sentence). You can revoke your consent at any time and exercise your other privacy rights as outlined in Section 10 below). Tredio also uses cookies on our Website(s) for website function and to enhance your user experience. 

More information on these three categories can be found below.


Below is a list of Data we may Access solely for the provision of our Platform Services to our clients. We may not receive all of the information listed below every time we provide the Platform Services; the information we receive is predominantly determined by each Publisher with which you interact.

    1. Online identifiers (IDs) – these are digital identifiers that may indirectly identify you and include:
      1. Cookies – small text files/code stored on your browser that allows us to collect information. More information on our cookies can be found within our Website and Cookie Notice.
      2. Pixels – HTML code snippets loaded when you visit a website that allows us to collect Data.
      3. Third-party online identifiers – IDs that belong to third parties. Third-party IDs may be associated to broad aggregate audience segments and shared with Buyers to serve more relevant ads to you based on your interests (e.g., ads related to sports or fashion).
        1. Our handling of your Data includes a process known as user matching. In this process, we match our cookies to the third-party IDs of our partners to provide more effective ways to deliver relevant ads to you.
    2. Browser information – information including, but not limited to, the type and version of your browser, browser settings (such as language and local time), user agent, and your IP address.
    3. Device Information – as applicable, general information including, but not limited to: device type (e.g., laptop, mobile, TV), model, manufacturer, operating system, time zone, telephone carrier information, network information (e.g., WIFI), and mobile application information. Mobile device information includes standard mobile advertising identifiers located on every mobile device. These are:
      1. IDFA – advertising identifier used on Apple’s iOS devices; and
      2. Google Advertising ID (AAID or GAID) – advertising identifier used on Android devices, to track your use of mobile apps on your device(s).
    4. Location information – geolocation information such as city, country, zip code/postal code, and/or longitude/latitude. We may receive location information from Publishers that is referred to as precise geolocation data.

A note on Cross Device Linking: Cross device linking is the process of tracking a user across multiple devices, for example, across a Smart TV, mobile, and/or website. Tredio does not directly participate in cross-device linking. However, some of our partners may engage in cross device linking to serve you more personalized advertising.

Tredio also does not measure click through rates, your browser history, or engage in retargeting, reidentification, or audience segmentation; however, some of our partners may engage in these practices.


We Access your Data to provide our Platform Services. Please find described below the business purpose(s) for which we process Data, and our legal basis for doing so:


We Access your Data (per Section 3 above) for the following business purpose(s):

  1. Ad delivery – to deliver ads to you on Publishers’ Digital Properties.
  2. Ad reporting – to verify an ad was delivered to you with accuracy.
  3. Troubleshooting, optimizing, and product improvement – to improve our Platform Services and ensure ads are delivered correctly to you.
  4. Ad vetting – to prevent fraud, malware, and other unacceptable behaviour.
  5. Privacy Rights – to view and enforce your opt-out choices, and honour your privacy choices/rights. For example, we may Access your Data if you make a request to delete your Data.

International law, such as European data protection law, requires us to have a legal reason for Accessing your Data. Tredio Accesses your Data under one or more of the following legal bases:

  1. Consent – Tredio may Access your Data if you provide Publishers with the consent for us to do so. This means, for example, if you visit a website that has a cookie banner and click “Accept All”, Tredio will receive a technical signal confirming that you are providing us with the consent to Access your Data.
  2. Legitimate Interest – we may also Access your Data if we have a legitimate reason to do so. For example, we Access your Data to provide our Platform Services. Such Platform Services allow you to view the free online content in which you may be interested (e.g., a news website or blogs). Tredio will not override your privacy and/or fundamental rights and freedoms to exercise our legitimate interests.

We may disclose, share, or sell (collectively, Share) your Data with the following partners for the purpose of delivering ads to you:

  1. BUYERS: As noted above, we connect Publishers with Buyers of ad space. Buyers include Demand-Side Partners (other intermediaries) and Ad Partners (advertisers and ad agencies). We Share your data with Buyers to source ads that may be relevant to your interest(s). Buyers may Share your information with their clients and partners for the provision of their services. Each Buyer processes and Shares Data in accordance with their own privacy policies.
  2. IDENTITY PARTNERS: On the instruction of Publishers, your Data may be Accessed and Shared by Identity Partners. These are independent companies that use online identifiers to group you into broad based, aggregated audience segments (i.e., age 25-35; interests: cars), which they have collected independently of Tredio. Tredio does not actively collect any audience segments about you, however our technology facilities the delivery of these audience-based identifiers to Buyers.
  3. QUALITY VENDORS: We may send your Data to third-party vendors that help maintain the integrity of our Platform Services; for example, by preventing malicious software (e.g., viruses, trojans), or traffic from non-humans (i.e., bots), from loading on the websites you browse.
  4. LEGAL REASONS: We may be required to disclose your Data to comply with our legal obligations, or in cases where we believe in good faith that such disclosure is required by law.

How we protect your Data: If we Share your Data with another company, it becomes subject to their privacy practices which may differ from the information found in this Policy. To help protect your Data, Tredio contractually requires Buyers to comply with applicable data protection and privacy laws and implement user-centric privacy practices.


Tredio is a global company. To provide our Platform Services, we may transfer your Data internationally to any of our data center locations, or to any Buyer’s international data center locations. We respect the security and confidentiality of your data while effecting these international transfers as described below:


We ensure any international transfers of your Data are compliant with the laws of that region, including the European General Data Protection Regulation (GDPR). Specifically, with respect to the European Economic Area (EEA), we ensure appropriate legal protections are in place when we transfer Data outside of the EEA to the United Kingdom (UK), Switzerland, or any other country, as provided for under European data protection legislation. These protections include using technical measures, such as encryption of Data, or a legal mechanism, such as the Standard Contractual Clauses (SCC), which are approved by the European Commission. The SCCs standardize the protections for any international transfers of your data from the EEA to other countries, thus providing you with assurance that your will be able to access your rights for the protection of Data in a manner consistent with European data protection law. In the event of any conflict between the terms of this Policy and such transfer mechanism, the terms of the transfer mechanism will govern.


Tredio will investigate and attempt to resolve any privacy-related complaints or concerns within forty-five (45) days of receipt. If you have an unresolved complaint or concern that we have not addressed satisfactorily or in a timely manner, you may contact the International Centre for Dispute Resolution/American Arbitration Association (“ICDR/AAA”), a US-based, third-party dispute resolution provider (free of charge).
