This Privacy Policy and Advertising Technology Notice explains how Antengo Inc., doing business as Sellwild (“Antengo,” “Sellwild,” “we,” “us,” or “our”), collects, uses, discloses and otherwise processes personal information.
This Privacy Policy applies to:
We refer to these products and activities collectively as the “Services.”
This Privacy Policy does not replace a publisher’s own privacy notice. When Antengo technology operates on a third-party website, application or other digital property, that publisher may separately collect and process personal information under its own privacy policy.
Antengo provides digital marketplace, eCommerce, advertising and publisher-monetization technology.
Our Services may enable publishers and application developers to:
Antengo works with publishers, mobile application developers, advertisers, advertising agencies, demand-side platforms, supply-side platforms, advertising exchanges, ad servers, data and identity partners, measurement providers, fraud-prevention providers and other advertising technology companies.
Depending on the Service and applicable agreement, Antengo may act as:
The information we collect depends on the Services involved, the way you interact with us, the publisher property you visit, the technology being used and the privacy choices associated with your browser or device.
You may provide us with:
Payment transactions may be processed by third-party payment providers. These providers generally collect and store complete payment-card information. Antengo may receive transaction identifiers, payment status, billing information and limited payment-method information.
When you interact with our websites, Services or technology, we or our partners may automatically collect:
This information is usually pseudonymous and does not directly identify an individual by name. However, privacy laws may treat online identifiers, device information and Internet activity as personal information.
Antengo does not intentionally collect precise GPS location through its Advertising Services unless that collection is expressly disclosed, permitted by applicable law and supported by any required consent.
We may receive information from:
We require partners to provide personal information lawfully and to obtain any notice, consent or other authorization required for the collection and transmission of that information.
We may create or receive inferences based on online activity, page or app context, advertisements viewed, approximate location, device information or other pseudonymous data.
These inferences may include:
We do not intentionally use sensitive personal information to infer sensitive characteristics or target advertisements based on sensitive characteristics.
When you visit a publisher website or application using Antengo technology, the publisher or Antengo may generate an advertising request.
That request may contain information such as:
Antengo may transmit some of this information to advertising partners so that they can determine whether to bid for the opportunity to display an advertisement and how much to bid.
The winning advertiser or demand partner may then provide an advertisement for display. Advertising creatives may include cookies, pixels, software-development kits or other technologies operated by the advertiser or its vendors for measurement, attribution, fraud prevention or other disclosed purposes.
Advertising partners may independently process information under their own privacy notices.
Contextual advertising is selected based primarily on information about the publisher, page, application, content or advertising placement rather than a profile of activity across unrelated services.
Where permitted, advertising may be personalized based on pseudonymous identifiers, prior interactions, inferred interests or activity across different websites, applications or services.
Depending on applicable law, this activity may be described as:
Where enabled and legally permitted, Antengo and its partners may associate or synchronize pseudonymous identifiers to recognize that different identifiers relate to the same browser or device.
This activity may be used to:
We process applicable consent, opt-out and restricted-processing signals when conducting these activities.
We may use personal information for the following purposes:
The legal basis for processing depends on the Service, purpose and jurisdiction.
Where the laws of the European Economic Area, United Kingdom, Switzerland or another jurisdiction require a legal basis, we may rely on:
We may rely on consent for:
You may withdraw consent through the applicable publisher’s consent-management platform or other privacy controls. Withdrawal does not affect processing that occurred before consent was withdrawn.
We may process information as necessary to:
Where permitted, we may process information for legitimate interests including:
We consider the nature of the information, reasonable expectations and potential impact on individuals before relying on legitimate interests.
We may process information to comply with legal obligations or protect the vital interests, rights or safety of an individual.
Antengo and its partners may use:
These technologies may be used for:
Where consent is required, non-essential technologies should not be activated until valid consent has been obtained.
Publishers using Antengo technology are responsible for operating an appropriate consent-management mechanism on their properties where required. Antengo may receive and process consent, opt-out and privacy signals passed by publishers and their consent-management platforms.
These signals may include:
Where a valid signal requires restricted processing, Antengo may limit processing to permitted activities such as contextual advertising, security, fraud prevention, frequency capping, measurement or other legally permitted business purposes.
We may disclose personal information to the following categories of recipients.
We may provide reporting, marketplace, advertising and performance information to publishers or application developers using our Services.
We may transmit advertising-request information to advertisers, agencies, demand-side platforms, exchanges and other buyers so they can:
When enabled for particular inventory, these partners may include TripleLift, Inc. and its demand partners. TripleLift’s Advertising Technology Platform Privacy Notice provides additional information about TripleLift’s processing. The words “TripleLift’s Advertising Technology Platform Privacy Notice” should be linked to TripleLift’s current platform privacy notice on the published webpage.
We may work with other supply-side platforms, advertising exchanges and resellers to make publisher inventory available to advertisers and demand partners.
Where enabled and permitted, we may disclose pseudonymous identifiers or receive matching information from identity or data partners for advertising delivery, measurement or addressability.
We may disclose information to providers that assist with:
We may use providers for:
These providers are subject to contractual restrictions appropriate to the services they perform.
Information may be disclosed to sellers, buyers, payment providers, shipping providers and other commerce partners when necessary to process or fulfill a marketplace transaction.
We may disclose information:
Information may be transferred in connection with a merger, financing, acquisition, restructuring, bankruptcy, sale of assets or similar corporate transaction.
Antengo does not sell personal information in exchange for money in the conventional sense.
However, certain disclosures of online identifiers, Internet activity, device information, approximate location or inferred interests to advertising partners may be considered a “sale,” “sharing,” targeted advertising or cross-context behavioral advertising under applicable U.S. state privacy laws.
During the preceding 12 months, Antengo may have sold or shared the following categories of personal information through its Advertising Services:
These categories may have been sold or shared with:
The purposes may include:
These activities are subject to applicable consent, opt-out and restricted-processing signals.
You may opt out of the sale or sharing of personal information and processing for targeted advertising through our Your Privacy Choices page.
The words “Your Privacy Choices” should be linked to Antengo’s functioning privacy-choice interface and should also appear as a conspicuous link in the footer of Antengo and Sellwild websites.
Where legally required, we also treat a qualifying browser-based opt-out preference signal, including Global Privacy Control, as a request to opt out for the browser or device transmitting the signal.
Opt-out choices are generally browser- and device-specific. Clearing cookies, changing browsers or changing devices may require you to renew your selection unless your choice is associated with an authenticated account or otherwise capable of being recognized.
You may also use privacy controls provided by your mobile operating system, browser or the publisher property you are visiting.

Where information is maintained as deidentified information under applicable law, we will not attempt to reidentify it except as legally permitted to test whether our deidentification processes are effective.
We use reasonable administrative, technical and organizational safeguards designed to protect personal information.
These measures may include:
No system or Internet transmission can be guaranteed to be completely secure. We therefore cannot guarantee that unauthorized access, loss, misuse or alteration will never occur.
Antengo’s Services are not directed to children under 13, and we do not knowingly collect personal information from children under 13.
We do not knowingly sell or share personal information belonging to individuals under 16 without legally required authorization.
