What is SDK X-Ray? How ARK Detects Risky App SDKs
SDK X-Ray is a mobile security feature in ARK Fortress that identifies third-party software development kits embedded in your installed apps, revealing which ones request excessive permissions or pose privacy risks.
SDK X-Ray explained
SDK X-Ray is a Fortress-tier feature of ARK: Mobile Security Score that scans your device's installed apps and identifies the third-party software development kits (SDKs) they use. Apps rarely work in isolation; most pull in code from external vendors for analytics, advertising, crash reporting, or login services. SDK X-Ray shows you which SDKs are present, what they do, and whether they request risky permissions or have known privacy issues. This visibility matters because SDKs are often the least-understood part of app ecosystems; a seemingly innocent app might bundle an analytics SDK that collects location data, or an ad SDK that tracks your behaviour across multiple apps.
Why SDKs matter for privacy
A single app install can quietly introduce a dozen SDKs into your device, each with their own data collection practices. Some are benign; others request microphone access, location history, or contact lists without obvious reason. SDK X-Ray surfaces this hidden supply chain, letting you understand exactly what third-party code is running on your phone and what it might be accessing. As of 2026, the average smartphone hosts hundreds of active SDKs across all apps. ARK's Fortress tier gives you visibility into which ones are installed and what permissions they've been granted, so you can make informed decisions about which apps to keep or uninstall.
What ARK's SDK X-Ray shows you
When you run an SDK X-Ray scan in ARK Fortress, the app identifies the embedded SDKs in your installed apps and displays them with context: the vendor name, the category (analytics, ads, crash reporting, login), and a risk indicator based on permission requests or known privacy concerns. You also get ARK's AI Opt-Out Hub, which provides one-tap deep-links to disable tracking or opt out of data collection within apps that support it, bypassing the need to dig through settings menus. The scan results don't require internet connectivity for analysis; ARK processes the data on-device when possible, respecting your privacy while delivering the insights.
How SDK X-Ray fits into ARK's broader security model
SDK X-Ray is one of six major security scans in ARK Fortress, alongside breach exposure checks, dark-web monitoring, phishing detection, password health audits, and Wi-Fi security analysis. Together, these scans generate your mobile security credit score, a 0-100 rating that updates as you patch vulnerabilities or remove risky apps. ARK also includes a stalkerware detector (free for all users), data-broker exposure checks, GDPR Autopilot for automated privacy requests, voice-clone risk alerts, and BYOD audits for small business users. Each scan delivers one-tap remediation, so you can act on findings immediately rather than reading a report and doing nothing.
Who should use SDK X-Ray
SDK X-Ray is designed for privacy-conscious users aged 25-45, people who've experienced data breaches, parents monitoring family devices, and small business owners managing multiple corporate phones. If you want visibility into third-party code running on your device, or you're concerned about invisible trackers and data collection, ARK Fortress's SDK X-Ray addresses that gap. It's particularly useful for users who've heard about data-broker exposure or SDK-based ad tracking but haven't had a straightforward way to audit it on their own phone.

Frequently asked questions
Is SDK X-Ray the same as antivirus scanning?
No. SDK X-Ray identifies third-party code and its permissions; it doesn't scan for malware or viruses. ARK focuses on privacy and data exposure, not antivirus protection.
Can I remove SDKs from my apps?
Not directly. SDKs are built into apps at development time. If an SDK's data collection concerns you, your options are to uninstall the app or disable app permissions that the SDK uses. ARK's AI Opt-Out Hub shows you privacy settings within each app.
Which ARK tier includes SDK X-Ray?
SDK X-Ray is a Fortress-tier feature (£7.99/mo or £79.99/yr). It's not available on ARK's free tier or Shield tier.
Does ARK store the results of SDK X-Ray scans?
On-device analysis is the default; ARK uses iOS SecureStore for any stored identifiers, never plain text. Fortress tier users can opt into cloud backup for historical scan results, but SDKs themselves are analysed locally first.
How often should I run an SDK X-Ray scan?
You can run it anytime, but SDK composition only changes when you install or update apps. Many users run it monthly or after installing new apps to check for permission changes.
