Knowledge privateness has change into a hot-button concern all through the know-how {industry}, and in June 2020, Apple shook up the cell advertising world with the announcement of recent person privateness rules starting with iOS 14. After a delay to provide builders time to adapt, these adjustments went into full impact with the discharge of iOS 14.5 in April of 2021.

Whereas Apple has beforehand added different options to provide customers extra perception and management over the info collected on their iOS gadgets, the introduction of those adjustments, such because the AppTransparencyFramework, mark a major shift in how cell person knowledge will be accessed and shared. For cell entrepreneurs each outdated and new, navigating the myriad particulars and implications of those adjustments will be overwhelming.
On this information, we offer a “again to fundamentals” walkthrough on the core ideas associated to person privateness starting with iOS 14.5 and past, together with understanding system identifiers, the IDFA, and the AppTrackingTransparency (ATT) Framework. We additionally talk about the small print of navigating SKAdNetwork, Apple’s attribution answer, in addition to different privacy-protecting, Apple-compliant attribution choices. At Regulate, we’ve labored intently with Apple and our companions and shoppers to be able to assist educate and supply options that meet the wants of builders, advertisers, and entrepreneurs whereas defending person privateness.
What’s a Gadget ID?
A tool identifier is a novel string of numbers and letters that identifies a person smartphone or pill. Gadget identifiers will be both a hard-coded system ID which is troublesome for customers to vary or reset, or an promoting ID, which is straightforward to reset and supposed for advertising use.
In a cell advertising context, a system ID usually refers back to the second possibility. Promoting IDs allow entrepreneurs to determine and observe person conduct from a tool with out revealing any private or figuring out details about the person. Utilizing system IDs, entrepreneurs can extra precisely observe particular person person conduct, permitting for correct attribution, putting customers into cohorts primarily based on identifiers, higher advert focusing on and optimization, and studying how customers work together with an app after set up.
There are two most important system ID varieties relying on working service. On Android, the system ID is named the GPS ADID (or Google Play Companies ID for Android). On IOS, it’s referred to as the Identification for Advertisers (IDFA).
What’s the IDFA?
The Identifier for Advertisers (IDFA) is a random system identifier that’s assigned to a person’s system by Apple. Just like a third-party cookie in a browser, it is utilized by entrepreneurs to trace a person’s interactions with commercials and cell apps, comparable to clicks, downloads, and purchases. Utilizing the IDFA, advertisers can ship focused adverts to customers with out revealing their private data.
The IDFA is probably the most exact approach to observe iOS customers and carry out attribution. By assigning a tool to a single IDFA, advertisers can determine when customers work together with a cell promoting marketing campaign, whether or not customers click on on a given commercial, and which in-app occasions the person triggers.
What’s the IDFV?
The Identifier for Distributors (IDFV) is an identifier assigned to all apps by one developer by Apple and shared throughout all apps from that developer on a tool. The worth of an IDFV is similar for all apps from the identical developer operating on the identical system. A unique worth is returned for apps on the identical system that come from completely different builders and for apps on completely different gadgets, whatever the developer.
Whereas the IDFA is assigned on the system degree and will be reset by customers, the IDFV is assigned to all apps by the one vendor and doesn’t persist as soon as all apps from that vendor are uninstalled. If the person deletes all apps from that vendor from the system after which reinstalls a number of of them, the worth of the IDFV will change. Sometimes, the IDFV is decided primarily based on knowledge supplied by the App Retailer concerning the developer. If the app was not put in from the App Retailer (for instance, enterprise purposes and apps in improvement), a supplier ID is calculated primarily based on the app’s bundle ID.
IDFVs are necessary as they supply a way to run cross-promotional iOS campaigns which embody customers who haven’t consented to sharing their IDFA. As long as an IDFV is handed in a tracker URL, the IDFV can present entrepreneurs with extra correct attribution knowledge for iOS campaigns.
What’s AppTrackingTransparency (ATT)?
Starting with iOS 14.5, person consent for advert monitoring is managed via the AppTrackingTransparency system (ATT). ATT is Apple’s framework for letting customers management when and the way their knowledge is shared with third events comparable to advert networks and analytics and measurement companions. The first purpose of ATT is to make sure customers have a transparent understanding of precisely what knowledge is shared from their system, and to restrict that sharing until the person grants consent.
In accordance with Apple’s tips, any iOS app that collects end-user knowledge and shares it with third events should use the ATT framework. So as to get hold of entry to a tool’s IDFA, app builders and their companions should obtain express consent from the person via an iOS system immediate. This consent can solely be granted by way of an opt-in, on a per-app foundation. With out that opt-in, the ATT won’t permit entry to and monitoring of the IDFA and person degree knowledge.
The ATT Immediate
So as to request entry to the IDFA from a person, an app can set off a one-time popup immediate to the person. The immediate is a system alert from Apple that the person will see when within the requesting app, and controls entry to the IDFA. Apps management if, when, and to whom the immediate is proven, however till a person opts-in utilizing this immediate, their IDFA won’t be accessible.
The alert consists of a header (which isn’t editable) and a subheader (which is editable), and two selections for the person. The header is written by Apple and states “Enable ‘app title right here’ to trace your exercise throughout different firms’ apps and web sites?” Beneath this can be a subheader which permits an app developer to state a motive for the request, comparable to “Your knowledge shall be used to supply you higher and customized adverts.”
The person has two choices to pick:
Enable Monitoring. If the person selects this, the app writer and their companions can learn the IDFA of the system.
Ask App To not Monitor. If the person selects this selection, the app writer and their companions can’t learn the IDFA. The immediate won’t ever be proven to the person on this app once more, until they uninstall and reinstall it.
Even when a person chooses “Ask App To not Monitor,” they’ll all the time go to their Settings for the app and select to share the IDFA. Moreover, customers can determine to toggle off the power for apps to ask for permission utilizing this immediate. With this selection chosen within the system’s Settings, anytime an app asks for permission, the popup by no means seems and the IDFA is returned to the writer as a string of zeros.
No matter this setting, even when the consent type by no means pops up, a developer can nonetheless hyperlink customers to the Settings for the app. They’ll do that at any time, and allow monitoring for this app, even when the above setting is off. With this mechanism, if the person agrees, they’ll all the time be despatched conveniently to the right app-level Settings web page and consent there.
ATT statuses
The ATT has 4 statuses of person consent, which decide entry to app-related knowledge that can be utilized for monitoring the system:
-
- 0 – Not Decided. This worth means the person has not but obtained the ATT immediate to be able to request entry to the IDFA.
- 1 – Restricted. This worth is returned if authorization to entry the IDFA is restricted.
- 2 – Denied.The person has denied entry to the IDFA. This contains having switched “Enable apps to request to trace” to OFF at a worldwide degree within the system’s Settings.
- 3 – Licensed.The person has granted permission to entry the IDFA.
Person opt-in
Some of the necessary methods for entrepreneurs to achieve success after iOS 14.5+ is to maximise person opt-in charges. In spite of everything, the upper the consent fee, the nearer you may be to pre-iOS 14 capabilities – which is a large aggressive benefit.
The ATT person consent popup can solely be triggered as soon as, so it’s essential to optimize for the opt-in. Take care to supply person expertise and set off the popup when customers are more likely to worth the app expertise in trade for system knowledge.
Don’t set off the pop-up instantly. Whereas it’s good to have the IDFA as quickly as potential for analytics functions, Regulate can backfill a tool’s knowledge with the IDFA when it may be retrieved. It’s extra necessary to ask at a time when the person is extra more likely to say sure.
Display worth. Earlier than asking the person to offer you one thing (they’ll possible say no), first present expertise and display your app’s worth, which is able to make the person extra prepared to share their knowledge in trade.
Use a pre-permission immediate to request consent previous to triggering the iOS pop-up. This immediate will be designed, custom-made, and worded to finest suit your app. To learn to develop a robust UX technique and persuasive pre-permission immediate, see our weblog publish on getting the opt-in.
Take into account the person’s relationship with the app, and previous experiences with the app, when crafting a message asking to trace the system. Thank the person and if potential, acknowledge the methods they’ve already used the app.
Present the long run worth the person can get in the event that they do consent to monitoring. Do you want to present focused adverts, or promote the person associated companies? In that case, show how that is for the good thing about the person.
Since Apple first introduced the AppTrackingTransparency framework in 2020, Regulate has labored with shoppers to organize and discovered quite a bit about what steps to take to enhance opt-in charges — and what steps to keep away from. To study the do’s and don’ts of utilizing design to enhance your opt-in charges, take a look at our weblog publish documenting key learnings on the subject.
What’s SKAdNetwork?
Along with the ATT, the second main implication of iOS 14.5+ is working with SKAdNetwork. SKAdNetwork is Apple’s answer for offering attribution for app installs and reinstalls with out sharing any user-level knowledge with the app developer.
Whereas it has “community” within the title, it’s truly a service supplied by Apple that consists of a mixture of SDK features and API calls. SKAdNetwork is free for app advertisers to make use of, and data supplied by SKAdNetwork will be relayed between the system, Apple, advert networks, and to advertisers and their companions comparable to Regulate utilizing callbacks. Attribution is first carried out by the App Retailer, is verified by Apple’s servers, and is cleansed of any user-level knowledge earlier than being despatched to advert networks or builders. To make use of SKAdNetwork, advert networks should register with Apple, and builders should work to make sure that their apps are suitable with the registered networks and the framework. Regulate helps an industry-leading variety of SKAdNetwork associate integrations.
The aim of SKAdNetwork is to supply fundamental, aggregated attribution knowledge whereas sustaining a excessive degree of system privateness. SKAdNetwork doesn’t present real-time knowledge, user-level knowledge, timestamps on installs or occasions, as an alternative providing a restricted variety of occasions, and solely the primary occasion of a post-install occasion. SKAdNetwork doesn’t at the moment assist deep linking (deferred or conditional), view-through attribution, and doesn’t contemplate something however the act of downloading as attributable.
SKAdNetwork is restricted to 100 completely different campaigns per community. On condition that there are sometimes numerous sub-campaigns for various geographies, system varieties, or creatives, this generally is a limiting issue for advertisers. For instance, the usage of ten creatives in 5 nations would solely permit two completely different campaigns per community.
Shoppers can implement SKAdNetwork both on their very own or with Regulate’s assist. When built-in with Regulate, Apple nonetheless performs the attribution, whereas Regulate aggregates the info.
What are conversion values on SKAdNetwork?
When an advert is clicked and the App Retailer is opened, the App Retailer will ship a notification to the advert community or app developer of a profitable conversion consisting of the Writer ID, community ID, and marketing campaign ID. Alongside this, a conversion worth shall be connected, which will be set by the app.
The conversion worth is a quantity between 0 and 63 (or between 000000 and 111111 in binary) that’s set by the advertiser to permit some fundamental post-install occasion monitoring. This notification and conversion worth is distributed at the least 24 hours after the primary time the person launches the app, to be able to stop with the ability to join the knowledge to a selected person id.
It’s as much as app builders to determine which occasions they wish to map onto the conversion worth; as an example, a sport could wish to observe level-ups. Nevertheless, there is a vital restrict to conversion values: they’re unidirectional, can solely progress upward, and should be mapped to occasions that happen within the first 24-hours post-install. For instance, let’s say a sport creates an occasion code for ‘Stage One’ that reads 000001. Then the person buys in-game forex, which is assigned a unique worth of 000011. If this person later completes ‘Stage Two,’ the bits can’t be modified to 000010, since adjustments in just one course are allowed. To keep away from this, builders must assign a bit worth to every path or mixture of potentialities, somewhat than to any particular person occasion.
One concern about these conversion values is they’re unsigned, which means that app builders will be unable to confirm whether or not the occasion came about with the identical degree of certainty as earlier than.
Conversion worth timer
When a person launches an app for the primary time, a timer begins for twenty-four hours till the conversion worth is distributed to the advert community. Each time the conversion worth is up to date as a consequence of an in-app occasion, the timer will get prolonged by an extra 24 hours.
As soon as the timer will get to zero, as no extra conversion occasions have occured inside a 24-hour interval, a second 24-hour timer for attribution begins counting down. At a random time inside this 24-hour window, the SKAdNetwork returns the attribution knowledge in an aggregated type, with no granular knowledge accessible on the person degree. This randomization and delay within the supply of the SKAdNetwork payload prevents any in-app occasion triggers comparable to log-ins or purchases from being linked to particular person customers. Nevertheless, this delay additionally prevents entrepreneurs from with the ability to carry out real-time optimization on their SKAdNetwork campaigns.
To benefit from SKAdNetwork, entrepreneurs must work totally throughout the first 24 hours, leveraging all knowledge potential to color a transparent image of person conduct. Unpacking the person behaviors that happen throughout the first 24 hours is the important thing to constructing conversion values that may precisely predict and assess the standard of the customers you’re buying. Since this knowledge can solely be gathered within the first 24 hours, app builders want to interact customers as a lot as potential inside that first 24-hour window. This may can help you acquire an understanding of the customers that carry out nicely long-term to be able to proceed to focus on and purchase them.
How does attribution work post-IDFA?
Given the AppTrackingTransparency framework, what choices for attribution on iOS does that go away entrepreneurs going ahead?
There are three choices for attribution after iOS 14.5: SKAdNetwork, deterministic attribution, and probabilistic attribution. Entrepreneurs have the selection of utilizing whichever mixture of those finest strategies most accurately fits their wants. Regulate can assist every of those strategies, and might present steerage on which can work finest for a specific app.
If a person consents to sharing the IDFA, deterministic attribution stays probably the most correct possibility for advertisers. Nevertheless, given opt-in charges, advertisers may even want to make use of SKAdNetwork. Whereas it has its limitations, it ought to be very correct in last-click attribution of aggregated installs. We imagine that utilizing all three strategies, whereas posing probably the most complexity, additionally supplies probably the most alternative.
What’s probabilistic attribution?
Probabilistic attribution is a type of attribution primarily based on chances, not ID or system matching (generally known as deterministic attribution). It depends on machine studying and statistical modeling strategies to determine conversions to a excessive diploma of likelihood, in a method that’s compliant with Apple’s tips.
Within the case of Regulate, probabilistic matching is our secondary attribution technique. We use system particulars to attribute installs to clicks and impressions with matching traits. As an MMP, we do not observe or goal customers throughout websites or apps. Our solely purpose is to attribute an set up to an engagement with some extent of certainty. Since 80% of installs occur throughout the first hour of a click on, this kind of attribution doesn’t require any persistent ID. We’re in a position to make predictions with short-term knowledge (comparable to time of click on, time of set up, and fundamental system data) that turns into out of date inside a number of hours.
Probabilistic attribution isn’t meant to switch SKAdNetwork and can by no means be as correct. Nevertheless, it supplies actual property to any advertisers operating campaigns. Probabilistic attribution supplies entrepreneurs with extra visibility into artistic knowledge, enabling them to investigate creatives, construct effectivity fashions round media spend, and enhance ROI. Nevertheless, combining attribution strategies can create a difficulty with duplicated attribution.
What’s duplicated attribution?
Duplicated attribution is an issue that may come up for advertisers operating adverts on a community that helps a mix of each deterministic attribution and SKAdNetwork, which leads to advertisers getting charged twice for a similar person. How does duplicated attribution happen?
Let’s say you might be operating a non-SKAdNetwork marketing campaign, and a person consents each on the writer app and your app, main the channel to trace the person utilizing the IDFA. Nevertheless, the person has additionally clicked on or seen a SKAdNetwork advert from one other media supply previously 30 days, main SKAdNetwork to provide credit score for the set up. As a result of SKAdNetwork set up knowledge is aggregated, there is no such thing as a approach to de-duplicate the attribution.
