Earlier this month, a massive data breach exposed the precise location data of millions of users across popular apps including Candy Crush, Tinder, and MyFitnessPal. The breach was particularly alarming because some of the affected apps were VPNs and privacy tools — apps that people trusted to protect their data.

This incident exposed the use of real-time bidding (RTB), which involves “data brokers” auctioning off your browsing activity and personal information to the highest bidder — all to power the advertising industry. Your location, device details, content you viewed, and other private information are shared with auction winners in milliseconds, often without your knowledge. According to the Electronic Frontier Foundation (EFF), “while only one advertiser wins the auction, all participants receive the data,” including malicious parties posing as ad buyers.
And that’s just one of the latest hacks in the news. With today being Data Privacy Day and new data breaches happening left and right, there’s no better time to take control of your digital privacy. While it can sound daunting, protecting yourself is simpler than you might think. Let's look at ten essential tools that can help protect your privacy in 2025.
Quick tip to get started:
Data brokers and apps are constantly trying to track your every move online. Here are two simple ways to throw them off:
- iPhone users: Head to Settings → Privacy & Security → Tracking and turn off "Allow Apps to Request to Track"
- Android users: Try DuckDuckGo's App Tracking Protection to block trackers
This helps limit the amount of personal information apps can collect and share.

The foundation of your online privacy starts with your browser. While Chrome and Safari collect some user data by default, Brave stands out by blocking trackers, third-party cookies, and ads automatically, putting privacy first.
What makes Brave stand out is how the browser prioritizes online privacy without sacrificing performance:
- No trackers or ads means web pages load noticeably faster, and pages aren’t cluttered with ads that make it hard to focus on content
- Direct connection to the decentralized web through IPFS lets you access content that can't easily be censored
- Private browsing with Tor integration helps hide your IP address and location
For anyone frustrated with Google's data harvesting or skeptical of Apple's privacy marketing, Brave offers a serious alternative. It's built on the same Chromium platform as Chrome, so you get familiar speed and compatibility — just with privacy protection turned on from the start.

DuckDuckGo: Private search engine

While most search engines store and build a profile of your every online move, DuckDuckGo takes a different route. Built around its privacy-first search engine, the platform offers tools that help you browse and search without becoming a data point for advertisers.
Key privacy features include:
- Private search with zero history collection or user profiling
- Standalone browser apps for Mac, Windows, iPhone and Android with built-in tracking protection
- Email protection service that strips trackers from your incoming messages
- Browser extensions for desktop to extend your privacy protection (you can add the DuckDuckGo extension to Brave)
The Gravy Analytics breach laid bare the dangers of unchecked app tracking, especially on Android devices. DuckDuckGo's tools act as a shield, blocking trackers before they can vacuum up your personal information.

Building your privacy stack
Privacy requires a multi-layered approach. Each tool we've covered plays a specific role: browsers block tracking, messaging apps protect communications, and monitoring tools watch for threats. When used together, these tools protect your personal information and online activity. Recent breaches remind us that our personal information is increasingly vulnerable. But with the right tools and protections in place, we can take back control of our privacy.
