Apple cracking down on 'fingerprinting' with new App Store API rules

Starting with iOS 17, developers will need to explain why they're using certain APIs.

As technology continues to advance, privacy concerns have become paramount for users and companies alike. With the increasing use of smartphones and mobile applications, user data and privacy have become hot topics in the tech industry. One practice that has raised significant concerns is device fingerprinting, a technique used by advertisers and data analytics companies to track users across different apps and websites. Acknowledging the importance of user privacy, Apple has taken a major step towards safeguarding user data by introducing new App Store API rules aimed at cracking down on 'fingerprinting.'

Understanding Device Fingerprinting

Before delving into Apple's latest move, it is essential to grasp what device fingerprinting entails. Device fingerprinting is a method used to identify and track devices based on various unique attributes, such as device type, operating system, screen resolution, installed fonts, and more.

By collecting this information, advertisers and data analytics firms can create a unique "fingerprint" for each device, allowing them to track users' online activities across multiple apps and websites.

The Privacy Concerns Associated with Fingerprinting

While device fingerprinting might seem like a harmless way to target users with personalized advertisements, it raises serious privacy concerns. Many users are unaware that their online activities are being tracked across various platforms, leading to a breach of their privacy without informed consent. Additionally, fingerprinting can be used to build detailed user profiles, which may then be sold to third parties, leading to potential misuse of personal data.

Apple's Initiative: New App Store API Rules

Apple, known for its commitment to user privacy, has taken a significant step to address the issues surrounding device fingerprinting. The tech giant recently introduced new rules for its App Store API, aimed explicitly at curbing fingerprinting practices. These rules impose strict limitations on the data that app developers can collect and use, promoting a more privacy-centric approach.

1. Prohibition of Fingerprinting Techniques

Apple's new API rules explicitly prohibit app developers from using fingerprinting techniques to track users across different apps or websites. This measure aims to safeguard user anonymity and prevent the creation of detailed user profiles without consent.

2. App Store Privacy Labels

In addition to the API rules, Apple has mandated the use of privacy labels for all apps available on the App Store. These labels provide users with clear and concise information about the data an app collects and whether it is used to track them across other apps or services.

3. Transparency and User Consent

Apple emphasizes transparency and user consent when it comes to data collection. App developers must now seek explicit permission from users before collecting any data that can be used for tracking purposes. This empowers users to make informed decisions about sharing their data.

4. Data Minimization

With the new rules, Apple encourages app developers to practice data minimization, meaning they should only collect the minimum amount of data necessary for app functionality. This helps reduce the risk of potential data misuse.

Impact on the Digital Advertising Landscape

While Apple's move towards tightening the reins on device fingerprinting is undoubtedly a win for user privacy, it has also sparked debates within the digital advertising community. Advertisers and marketers heavily rely on user data to deliver targeted advertisements, and the limitations imposed by Apple's new rules might impact their ability to precisely target specific audiences.

However, this move could prompt advertisers to explore alternative, more privacy-friendly advertising practices that do not rely on intrusive data collection. Concepts like contextual advertising, where ads are shown based on the content of the app or website being used, are likely to gain traction.

The Future of User Privacy

Apple's proactive approach to safeguarding user privacy sets an essential precedent in the tech industry. As concerns over data privacy continue to grow, other tech giants may follow suit, implementing similar measures to protect their users.

In an era where data breaches and privacy violations make headlines regularly, users are becoming increasingly vigilant about their online privacy. Apple's move is a clear signal that protecting user data should be a top priority for all companies in the digital landscape.


As technology evolves, so do the challenges surrounding user privacy. Apple's latest initiative to crack down on 'fingerprinting' with new App Store API rules is a significant step towards protecting user data and ensuring transparency in data collection practices. By prohibiting fingerprinting techniques, promoting transparency, and advocating for user consent, Apple is setting a standard for user privacy in the tech industry.

This proactive approach will likely have a ripple effect on the digital advertising landscape, pushing advertisers to adopt more privacy-friendly practices. While the debate on balancing user privacy and targeted advertising continues, it is evident that user data protection is gaining momentum as a critical aspect of the digital world.
