What is ARK's AI Opt-Out Hub?
ARK's AI Opt-Out Hub is a Fortress-tier feature that automates data-subject access requests under GDPR, letting you opt out of AI training datasets and control how your personal data is used by tech companies.
How the AI Opt-Out Hub works
The AI Opt-Out Hub sits inside ARK's Fortress tier and handles the legal groundwork of GDPR data-subject requests on your behalf. Instead of manually writing emails to each company that holds your data, the hub generates and submits formal opt-out notices to major platforms and data brokers. It tracks which requests have been sent, their status, and any responses. This matters because as of 2026, major AI companies are training models on personal data harvested from social media, email services, and data brokers. The hub gives you a way to formally object without legal fees or guesswork.
What data does it help you control?
The hub focuses on data commonly used in AI training: your email address, public social profiles, browsing history captured by data brokers, and any personally identifiable information collected by third-party services. ARK first identifies which companies and data brokers have your information using its data-broker exposure scan, then the hub generates compliant opt-out requests. You remain in control at every step. No data is deleted without your say-so, and ARK logs what was requested on your behalf so you can follow up manually if needed.
Why this matters for mobile security
Your phone is the window through which most of your digital life flows. Apps, browsers, and services collect fragments of your identity every day, and much of that data ends up in third-party hands. ARK's Fortress tier connects the dots: it runs breach checks, stalkerware detection, and now the AI Opt-Out Hub to cover the full lifecycle of your personal data. This isn't just about privacy compliance. It's about reducing your attack surface. The less data about you circulating in marketplaces and training datasets, the lower your risk of identity fraud, targeted phishing, or social engineering.
ARK's full mobile security stack
The AI Opt-Out Hub is one tool in ARK's layered approach. Your phone gets a 0-100 security credit score that breaks down your risk across device security, network exposure, app permissions, and breach history. Shield tier adds dark-web monitoring, phishing scanning via QR and URL analysis, Wi-Fi security audits, and password health checks. Fortress (which includes the AI Opt-Out Hub) layers on data-broker exposure mapping, voice-clone risk detection, GDPR autopilot for automated requests, and SDK X-Ray to see which third-party software libraries are embedded in your apps. Each finding comes with one-tap remediation links, so you don't have to guess what to do next.
Privacy-first scanning on your device
ARK keeps your data local by default. On the free tier, all scans run on your phone using on-device analysis. Paid tiers (Shield and Fortress) add cloud-based features like dark-web monitoring and breach checking, but only with your explicit consent. No analytics are collected on free-tier scans, and any data sent to our servers for premium features is encrypted in transit and stored securely. This matters for the AI Opt-Out Hub too: your GDPR requests are generated and tracked with minimal exposure.

Frequently asked questions
Is the AI Opt-Out Hub the same as a VPN or antivirus?
No. ARK is not a VPN (it doesn't mask your traffic) or an antivirus (it doesn't scan for malware). The AI Opt-Out Hub is specifically a GDPR compliance and data-subject rights tool. It works alongside ARK's security scanning to give you a complete picture of your phone's exposure.
Does ARK store my passwords or personal information?
ARK does not store your passwords. Personal information (like email addresses used in breach checks) is encrypted in iOS SecureStore, never stored in plain text. Your GDPR requests are tracked, but your data is processed with encryption throughout.
Which tier includes the AI Opt-Out Hub?
The AI Opt-Out Hub is part of the Fortress tier (£7.99/mo or £79.99/yr). Shield tier (£2.99/mo or £29.99/yr) includes breach monitoring and dark-web alerts but not automated GDPR requests. The free tier includes stalkerware detection and basic permission audits.
Can I use ARK on Android?
ARK is currently iOS only. If you need mobile security on Android, we recommend looking at our full app portfolio on MRVL Hub for other platforms.
How long does it take to see results from the AI Opt-Out Hub?
ARK generates and logs the requests immediately, but response times from companies vary. GDPR law typically gives companies 30 days to respond. ARK tracks the status of each request so you can follow up if needed.
