Your Privacy, Secured: Inside the Tech Powering Safe, Personalized Galaxy AI Experiences

The potential of AI is limitless, but to truly unlock its possibilities, user inputs that power personalized experiences are key for those who want to get the most out of their AI tools. When AI understands you — your preferences, and your routines — it can deliver a mobile experience that feels like a natural extension of your everyday life.

Intuitive, context-aware Galaxy AI¹ features bring personalized experiences to life, transforming your smartphone from a tool to a smart companion that offers suggestions designed to make you more productive, creative, and connected.

To deliver a personalized experience, your device needs access to certain personal data. It allows AI to understand you and tailor its responses in ways that can make your life more seamless. To protect your personal data in this era of AI, Samsung is constantly innovating to enhance data protection on your device.

Personalization Made Possible with Personal Data Engine

Samsung’s Personal Data Engine² (PDE) is a key component of realizing these highly personalized experiences safely. First introduced with the Galaxy S25 series, the PDE is the powerhouse behind some of Galaxy’s most life-changing AI experiences yet. It learns from your patterns and preferences, creating a personalized experience tailored to you.

Whether it’s Now Brief³ guiding you through your day with curated updates, or simply finding that one perfect photo in your Gallery⁴ by describing it in natural language, Galaxy AI makes AI-powered actions feel seamless. And because the PDE processes many important pieces of data safely on-device, you get all the benefits of deeply customized AI — without compromising on privacy.

Powerful Advancements with Knox Enhanced Encrypted Protection

To deliver these personalized Galaxy AI experiences safely, Samsung has developed Knox Enhanced Encrypted Protection (KEEP) — a powerful new layer of on-device security that protects your sensitive data, without interrupting your experience. First developed for the Personal Data Engine, KEEP now also safeguards other Galaxy AI features including Smart Suggestions, Now Brief, Samsung Moments, and more to give each supported app its own secure environment.

Think of your phone like a house. Each app has its own room — separate, but all under the same roof. Then there’s Secure Folder,⁵ which works like a fully detached guesthouse with its own key, set apart from the main home. It’s great for keeping certain things extra private, offering added peace of mind. But as AI features like the Personal Data Engine start handling more sensitive tasks in real time, there’s a growing need for security that’s just as strong but more connected to your everyday experience.

That’s where KEEP comes in. Imagine turning part of the house into a private suite — still under the same roof, but with its own secure entrance that only you can use. It’s more private than a regular room, but not completely separate like the guesthouse. KEEP works the same way: it creates a secure, dedicated space for individual apps, like the Personal Data Engine, so it can safely handle your data without sending it anywhere or getting in the way of how you use your phone.

As our mobile experiences become more intelligent, KEEP is designed to protect your most personal data. Together with tools like Secure Folder, it reinforces Samsung’s multi-layered approach to protection — giving both users and services the right type of security for different privacy needs.

With Galaxy AI being able to offer personalized experiences, features like the Personal Data Engine and Knox Enhanced Encrypted Protection offer powerful ways to keep your data safe by putting personalization and privacy protections hand in hand. Even as these experiences grow smarter and more attuned to your needs, we’re committed to keeping your most sensitive information protected on your device, exactly where it belongs.

5 Secure Folder offers users a separate and protected area of their phone or tablet to store sensitive apps and data. It allows users to set up separate profiles which can duplicate their apps. Users have the option to customize the Secure Folder app and set up their own lock type, including PIN, pattern, password and fingerprint. For enhanced security, users of Secure Folder are also provided with an option to hide and encrypt the Secure Folder, which helps keep data safe from advanced cybersecurity threats. While hidden, the apps will stop working, in order to keep the data safe. Once the Secure Folder is opened again, the encryption will be deactivated, and the apps will resume normal operation.
