Personal Data Stores (PDS) & Solid Pods Explained – How to Own Your Data in 2025
Introduction – The Myth of “Owning Your Data”
Last week, I wrote about Cognitive Sovereignty—the ability to protect our minds from manipulation in the digital era. But sovereignty is meaningless if we don’t first address the foundation: who actually controls our data.
Most of us believe that downloading an archive from Google or Meta means we “own” our data. That’s a myth. At best, it’s like asking your landlord for photocopies of the house you rent—useless without the keys.
In 2025, a quiet revolution is taking shape through Personal Data Stores (PDS) and Solid Pods, giving individuals like us the power to store, move, and control their data on their own terms. This is not a futuristic dream; it’s already here. And it may be the most practical step toward true digital sovereignty.
What is a Personal Data Store (PDS)?
A Personal Data Store (PDS) is your private vault of digital life—a place where your information lives under your control, not Facebook’s servers or Google’s cloud.
- You decide who can access what, and for how long.
- You can revoke access at any time.
- Apps don’t “own” your data; they simply request permission to use it.
Think of it as flipping the data economy upside down: instead of apps hoarding your data, you host your data and let apps come to you.
Enter Solid Pods: Tim Berners-Lee’s Answer to the Data Monopoly
The most prominent implementation of PDS today is Solid Pods, created by Tim Berners-Lee, the inventor of the World Wide Web. His frustration is obvious: the internet he built for openness has become a handful of walled gardens.
Solid Pods aim to:
- Break the silos: Your health data, social connections, and photos shouldn’t live in separate prisons.
- Enable portability: Switch apps without losing history, friends, or preferences.
- Protect privacy: Fine-grained permissions (e.g., “share this photo with this app for 24 hours”).
In short, Pods give you the keys to the house, not just the photocopies.
PDS vs. Data Wallets vs. SSI (A Quick Comparison)
| Feature | Personal Data Store (PDS) | Data Wallet | Self-Sovereign Identity (SSI) |
| Main Purpose | Store and control your data | Hold verifiable credentials | Manage digital identity |
| Examples | Solid Pods | DigiLocker | IGNOU |
| Control | Full data storage + permissions | Credential-focused | Identity-focused |
| Use Cases | Health records, social graph, files | University degrees, KYC | Login, identity verification |
| Sovereignty Level | High | Medium | Medium |
Why This Matters in 2025
- AI Needs Data, You Need Control
AI agents are becoming our daily assistants. But they’re only as useful as the data they can access. Do you want your agent tied forever to one company’s ecosystem? PDS ensures your AI works for you—not Google, not Meta, not Amazon. - Regulations Are Catching Up
Governments are tightening rules on data portability and privacy (GDPR in Europe, India’s DPDP Act). Solid Pods align with this shift, making adoption more likely. - The Trust Crisis
Every scandal—Cambridge Analytica, spyware apps, data breaches—pushes people to ask: “Why do companies need to own my data at all?” PDS answers: They don’t.
Real Use Cases Already Emerging
- Healthcare: A patient controls medical records and grants temporary access to a doctor or AI health assistant.
- Education: Students own their certifications and share them instantly with employers.
- Social Media: Imagine posting once, but choosing whether LinkedIn, Facebook, or a niche community can display it.
AI Agents: Your “personal AI” pulls directly from your PDS—no risk of Meta or OpenAI scraping your life without consent.
The Obstacles Nobody Talks About
Let’s be brutally honest: the dream of PDS is powerful, but adoption is hard.
- UX is painful: Setting up a Solid Pod isn’t as easy as signing into Gmail.
- Ecosystem gap: Not all apps integrate directly with Pods (yet).
- Convenience vs Control: People still trade privacy for “free” services.
- Corporate resistance: Why would Meta or Amazon give up its treasure chest of behavioral data?
But here’s the truth: all revolutions look impractical at the start. Remember when people said “no one will shop online”?
My Take – The Next Internet Is Local
We’ve been fooled into thinking our data belongs on someone else’s server farm. That mindset is the root of the problem. PDS flips the architecture of the web—it makes your device the hub, not their cloud.
Just as we’re moving toward local-first AI (models that run on your phone, not OpenAI’s servers), the local-first internet is inevitable. PDS and Solid Pods are simply the first visible wave. And once AI agents become mainstream, they’ll demand it. Your agent won’t work unless it can freely pull your data without begging 10 different companies. That pressure alone could accelerate PDS adoption faster than most expect.
How to Get Started (Practical First Step)
If you’re curious, you can create your own Solid Pod today:
- Sign up at Solid Community Pods (free starter pod).
- Store a simple dataset (like your contact list).
- Experiment by sharing it with a Solid-compatible app.
This is the equivalent of setting up your first email account in the 1990s—you won’t see the full picture yet, but you’ll feel the paradigm shift.
FAQs
Q: Is a Personal Data Store the same as downloading my data from Google?
No. Downloads are static copies; PDS is a living store that apps can query with your consent.
Q: Can Solid Pods replace social media?
Not directly. They’re the backend. Social networks could plug into your Pod, but they’d no longer own your data.
Q: Is this only for techies?
Right now, yes. But like websites or email in the ’90s, tools will get simpler.
Q: Who’s backing this?
Tim Berners-Lee’s company Inrupt, the Open Data Institute, and universities are already piloting PDS projects.
Conclusion – Sovereignty Isn’t Given, It’s Taken
Owning your data isn’t a product you buy; it’s a power shift you claim. Personal Data Stores and Solid Pods won’t solve everything overnight, but they’re the closest thing we have to digital independence.
If Cognitive Sovereignty is about protecting the mind, then Data Sovereignty is about protecting the self. And in 2025, that fight has only just begun.
