The company that created the technical spec for the China Advertising ID (CAID), Reyun, was acquired by Chinese mobile ad tech company Mobvista last month.

One of many corporations that created the technical specs for the China Advertising ID (CAID) was acquired final month by Chinese language cell advert tech firm Mobvista.

One can consider Reyun, which helped developed the code for CAID on behalf of the state-backed China Promoting Affiliation (and whose identify in Chinese language – 热云数据 – roughly interprets to “Sizzling Cloud Information”), because the equal of third-party cell measurement agency Modify, however particularly centered on the China market.

Adjust was itself recently acquired by AppLovin in a deal value $1 billion. Mobvista snagged the Beijing-based Reyun for 1.5 billion RMB, or simply greater than $233 million. It’s planning to make use of Reyun’s cell measurement tech to assist builders outdoors of China develop their apps within the huge China market.

As a refresher, CAID is a stand-in for the IDFA that was designed to circumvent Apple’s AppTrackingTransparency framework on iOS 14.

The expertise gathers a bunch of various non-distributed metadata, aka knowledge that lives on a tool (nation, time zone, language, machine identify, bodily reminiscence, and so on.) and assembles it to generate an ID that isn’t deterministic however is ample sufficient for use for advert measurement.

If that appears like fingerprinting, that’s as a result of it just about is. And Apple’s ATT privateness framework explicitly prohibits fingerprinting.

The FT broke the news of CAID’s existence in March. Though Apple didn’t touch upon CAID particularly, it did say in an announcement that “the App Retailer phrases and tips apply equally to all builders around the globe” and “apps which are discovered the disregard the person’s selection shall be rejected.”

Though some builders and even advertisers had started testing CAID as of March – together with P&G, TikTok guardian firm ByteDance and Tencent – anybody utilizing CAID as a alternative for the IDFA is in for a impolite awakening, mentioned Clement Cau, CEO and co-founder of Mobvista.

“For those who use CAID SDK knowledge and Apple sees, you’ll obtain an e-mail from Apple and be faraway from the App Retailer,” he mentioned.

The identical is true of any associated expertise. And but some corporations appear to have an urge for food for threat. Though nobody will say publicly that it is monitoring customers throughout totally different functions on the server aspect, it is taking place, Cau mentioned.

“Firms have their very own options, however this type of calculated server-side expertise can’t be utilized in the long run,” he mentioned. “Everybody, together with each large platform, together with us, are solely capable of optimize primarily based on the aggregated knowledge that comes from SKAdNetwork postbacks.”

Mobvista’s rationale for buying the corporate, Cau mentioned, is to assist make the Chinese language market extra accessible to abroad builders that aren’t aware of its idiosyncrasies.

“It’s a really totally different cell ecosystem in China, but it surely’s one of the crucial necessary markets,” he mentioned. “And if builders wish to achieve success in China, they want a localized resolution.”

Story up to date to replicate that a number of corporations had been concerned in growing the CAID spec.
