Your VPN or ad-blocker app could be collecting your data

Written by Toni Morrison

The underpinnings of how app retailer analytics platforms function have been uncovered this week by BuzzFeed, which uncovered the community of cellular apps utilized by a preferred analytics agency Sensor Tower to amass app information. The corporate had operated at the very least 20 apps, together with VPNs and advert blockers, whose principal objective was to gather app utilization information from finish customers with a purpose to make estimations about app tendencies and revenues. Sadly, these kinds of knowledge assortment apps are usually not new — nor distinctive to Sensor Tower’s operation.

Sensor Tower was discovered to function apps reminiscent of Luna VPN, for instance, in addition to Free and Limitless VPN, Cellular Knowledge, and Adblock Focus, amongst others. After BuzzFeed reached out, Apple eliminated Adblock Focus and Google eliminated Cellular Knowledge. Others are nonetheless being investigated, the report mentioned.

Apps’ assortment of utilization information has been an ongoing concern throughout the app shops.

Fb and Google have each operated such apps, not all the time transparently, and Sensor Tower’s key rival App Annie continues to do the identical as we speak.


For Fb, its 2013 acquisition of VPN app maker Onavo for years served as a aggressive benefit. The site visitors by means of the app gave Fb perception into what different social functions have been rising in reputation — so Fb might both clone their options or purchase them outright. When Apple lastly booted Onavo from the App Retailer half a decade later, Fb merely introduced again the identical code in a brand new wrapper — then known as the Fb Analysis app. This time, it was a bit extra clear about its information assortment, because the Analysis app was truly paying for the info.

However Apple kicked that app out, too. So Fb final 12 months launched Research and Viewpoints to additional its market analysis and information assortment efforts. These apps are nonetheless reside as we speak.


Google was additionally caught doing one thing comparable by the use of its Screenwise Meter app, which invited customers 18 and up (or 13 if a part of a household group) to obtain the app and take part within the panel. The app’s customers allowed Google to gather their app and net utilization in trade for present playing cards. However like Fb, Google’s app used Apple’s Enterprise Certificates program to work — a violation of Apple coverage that noticed the app eliminated, once more following media protection. Screenwise Meter returned to the App Store last year and continues to trace app utilization, amongst different issues, with panelists’ consent.

App Annie

App Annie, a agency that instantly competes with Sensor Tower, has acquired cellular information corporations and now operates its personal set of apps to trace app utilization beneath these manufacturers.

In 2014, App Annie purchased Distimo, and as of 2016 has run Cellphone Guardian, a “safe Wi-Fi and VPN” app, beneath the Distimo model.

The app discloses its relationship with App Annie in its App Retailer description, however stays obscure about its true objective:

“Trusted by greater than 1 million customers, App Annie is the main international supplier of cellular efficiency estimates. Briefly, we assist app builders construct higher apps. We construct our cellular efficiency estimates by studying how folks use their units. We do that with the assistance of this app.”

In 2015, App Annie acquired Mobidia. Since 2017, it has operated a real-time information utilization monitor My Knowledge Supervisor beneath that model, as effectively. The App Retailer description solely affords the identical obscure disclosure, which implies customers aren’t seemingly conscious of what they’re agreeing to.


The issue with apps like App Annie’s and Sensor Tower’s is that they’re marketed as providing a selected perform, when their actual objective for current is completely one other.

The app corporations’ protection is that they do disclose and require consent throughout onboarding. For instance, Sensor Tower apps explicitly inform customers what’s collected and what’s not:


App Annie’s app affords an identical disclosure, and takes the additional step of figuring out the guardian firm by title:

App Annie additionally says its apps can proceed for use even when data-sharing is turned off.

Regardless of these opt-ins, finish customers should still not perceive that their VPN app is definitely tied to a a lot bigger information assortment operation. In any case, App Annie and Sensor Tower aren’t family names (except you’re an app writer or marketer.)

Apple and Google’s accountability 

Apple and Google, let’s be truthful, are additionally culpable right here.

In fact, Google is extra pro-data assortment due to the character of its personal enterprise as an advertising-powered firm. (It even tracks customers within the real-world by way of the Google Maps app.)

Apple, in the meantime, markets itself as a privacy-focused firm, so is deserving of elevated scrutiny.

It appears unfathomable that, following the Onavo scandal, Apple wouldn’t have taken a more in-depth look into the VPN app class to make sure its apps have been compliant with its guidelines and clear in regards to the nature of their companies. Specifically, it appears Apple would have paid shut consideration to apps operated by corporations within the app retailer intelligence enterprise, like App Annie and its subsidiaries.

Apple is unquestionably conscious of how these corporations purchase information — it’s widespread trade information. Plus, App Annie’s acquisitions have been publicly disclosed.

However Apple is conflicted. It needs to guard app utilization and consumer information (and be recognized for safeguarding such information) by not offering any broader app retailer metrics of its personal. Nevertheless, it additionally is aware of that app publishers want such information to function competitively on the App Retailer. So as an alternative of being proactive about sweeping the App Retailer for information assortment utilities, it stays reactive by pulling choose apps when the media places them on blast, as BuzzFeed’s report has since achieved. That permits Apple to take care of a veil of innocence.

However pulling consumer information instantly covertly is just one option to function. As Fb and Google have since realized, it’s simpler to run these kinds of operations on the App Retailer if the apps simply say, mainly, “it is a information assortment app,” and/or supply fee for participation — as do many advertising analysis panels. This can be a extra clear relationship from a client’s perspective too, as they know they’re agreeing to promote their information.

In the meantime, Sensor Tower and App Annie competitor Apptopia says it examined then scrapped its personal an advert blocker app round six years in the past, however claims it by no means collected information with it. It now favors getting its information instantly from its app developer clients.

“We are able to confidently state that 100% of the proprietary information we accumulate is from shared App Analytics Accounts the place app builders proactively and explicitly share their information with us, and provides us the correct to make use of it for modeling,” acknowledged Apptopia Co-founder and COO, Jonathan Kay. “We don’t accumulate any information from cellular panels, third-party apps, and even on the consumer/machine degree.”

This method (which is utilized by the others as effectively) isn’t essentially higher for finish customers, because it additional obscures the info assortment and sharing course of. Shoppers don’t know which app builders are sharing this information, what information is being shared, or the way it’s being utilized. (Luckily for many who do care, Apple permits customers to disable the sharing of diagnostic and utilization information from within iOS Settings.)

Knowledge assortment achieved by app analytics companies is just one of many, many ways in which apps leak information, nonetheless.

The truth is, many apps accumulate private information — together with information that’s much more delicate than anonymized app utilization tendencies — by way of their included SDKs (software program growth kits). These instruments permit apps to share information with quite a few know-how corporations together with advert networks, information brokers, and aggregators, each giant and small. It’s not unlawful and mainstream customers in all probability don’t find out about this both.

As a substitute, consumer consciousness appears to crop up by means of conspiracy theories, like “Fb is listening by means of the microphone,” with out realizing that Fb collects a lot information it doesn’t really want to take action. (Nicely, besides when it does).

Within the wake of BuzzFeed’s reporting, Sensor Tower says it’s “taking instant steps to make Sensor Tower’s connection to our apps completely clear, and including much more visibility across the information their customers share with us.”

Apple, Google, and App Annie have been requested for remark. Google isn’t offering an official remark. Apple didn’t reply.

Sensor Tower’s full assertion is under:

Our enterprise mannequin relies on high-level, macro app tendencies. As such, we don’t accumulate or retailer any personally identifiable data (PII) about customers on our servers or elsewhere. The truth is, based mostly on the way in which our apps are designed, such information is separated earlier than we might presumably view or work together with it, and all we see are advert creatives being served to customers. What we do retailer is extraordinarily excessive degree, aggregated promoting information that will reveal tendencies that we share with clients.

Our privateness coverage follows finest practices and makes our information use clear. We wish to reiterate that our apps don’t accumulate any PII, and subsequently it can’t be shared with some other entity, Sensor Tower or in any other case. We’ve made this very clear in our privateness coverage, which customers actively choose into in the course of the apps’ onboarding processes after being proven an unambiguous disclaimer detailing what information is shared with us. As a routine matter, and as our enterprise evolves, we’ll all the time take a privacy-centric strategy to new options to assist make sure that any PII stays uncollected and is absolutely safeguarded.

Primarily based on the suggestions we’ve acquired, we’re taking instant steps to make Sensor Tower’s connection to our apps completely clear, and including much more visibility across the information their customers share with us.

App Annie shared the next:

App Annie doesn’t use root certificates at any level in its information assortment course of.

App Annie discloses that when customers choose into information assortment (and information sharing just isn’t obligatory to make use of our apps), information will likely be shared with App Annie for the needs of making market analysis. We solely accumulate information after customers expressly consent to this assortment inside our apps. We’re very clear, each on the app shops and within the apps themselves and clearly join App Annie to our cellular apps.
