In November, Google will ban Android VPN apps in its Play Store from interfering with or blocking advertising, a change that could cause problems for some privacy apps.
Google Play’s updated policy, announced last month, will go into effect on November 1. It states that only applications using the Android VPNService base class, and which function primarily as VPNs, can open a secure device-level tunnel to a remote service.
These VPNs, however, cannot “manipulate ads that may impact app monetization.”
The rules appear to be intended to deter data-logging VPN services, such as Facebook’s abandoned Onavo, and prevent ad fraud. The T&Cs specify that developers must declare use of the VPN service in their apps’ Google Play listing, must encrypt device data at the VPN endpoint, and must comply with Developer Program policies, in particular those related to ad fraud, permissions and malware. .
Blokada, a Swedish maker of an ad-blocking VPN app, fears the rule will hamper at least the previous iteration of its software, v5, and other privacy-focused software.
“Google claims to be cracking down on apps that use the VPN service to track user data or redirect user traffic to earn money from ads,” wrote Reda Labdaoui, head of marketing and sales at Blokada, the last week in a forum post.
“However, these policy changes also apply to apps that use the service to filter traffic locally on the device.”
Labdaoui suggests that Blokada v6, which launched in June, shouldn’t be affected because it filters in the cloud without violating Google’s device policies. But other apps may not be so lucky.
Labdaoui points to the DuckDuckGo privacy browser for Android, which creates a local VPN service for its app tracking protection to block tracking server connections, as a potential victim of the new Play policy.
DuckDuckGo, however, is unconvinced. “We don’t believe we will be impacted by the policy, but our team continues to review it,” a company spokesperson said. The register in an email.
Another app that could be affected is Jumbo for Android, which also appears to be using VPN-related code to block trackers.
Google’s policy is not unique. Apple’s iOS App Store includes a similar requirement to use a specific VPN API, named NEVPNManager, which is only available to developers who are part of an organization, not individual unaffiliated developers.
While Apple’s VPN rules don’t specifically address ad interference, it’s likely that the iOS guidelines leave ample room for interpretation that Apple might ban an iOS app that interferes with the operation of other applications, if desired.
For years, Google has banned Android apps that block ads in other Android apps (except browsers), and its Chrome Web Store includes language that could be used to ban ad-blocking extensions if Google chose to do so. For example, “We don’t allow content that harms or interferes with the operation of Google’s or third-party networks, servers, or other infrastructure.”
However, Google has said it wants to let developers “create more secure and better performing ad blockers”, even though its pending Manifest v3 transition seems likely to make these extensions less efficient.
