In an era where personal data is a commodity, privacy isn’t just a feature — it’s a fundamental right. As VP of Design at REALLY, the world’s first privacy-focused wireless carrier, I led the creative vision for a company that challenged the status quo of the telecom industry. Our approach was rooted in a simple but radical idea: assume that every user’s data is already exposed and build systems that protect them from further harm. This meant designing for anonymity by default, minimizing data collection, and ensuring users stayed in control of their information.

Privacy-first design isn’t just about compliance or security — it’s about trust, transparency, and reshaping the relationship between users and technology. In this piece, I’ll share practical strategies for designing products that prioritize user privacy in a world that too often exploits it.

Principles of Privacy-First Design

At the heart of privacy is a commitment to ethical design. I’ve come up with 8 key principles to guide my approach:

1. Minimize Data Collection

Only collect what’s absolutely necessary. Every piece of data you request increases risk. If a feature can function without personal information, don’t ask for it.

Example: Instead of requiring email or phone numbers, offer guest access or one-time authentication codes that don’t tie users to a persistent identity.

2. Transparency & Explainability

Tell users what’s happening to their data in plain language. People can’t make informed decisions if they don’t understand how their information is used.

Example: Create a “kid-friendly” privacy policy with visuals to ensure users understand their rights and how information is handled.

3. Automatic Data Expiration

Delete user data when it’s no longer needed. Holding on to unnecessary data increases the risk of leaks and abuse.

Example: Auto-delete all user data after 24 hours instead of storing it indefinitely.

4. No Dark Patterns

Respect user choices without manipulation. Privacy settings shouldn’t be buried in menus, use misleading language, or require unnecessary steps to enable stronger protections.

Example: Instead of “Are you sure you want to disable personalized ads?” (with the scary implication of a worse experience), use “Turn off ad tracking” with a simple toggle.

5. Decentralization & User Control

Where possible, let users own and store their own data. Centralized data stores are a prime target for breaches and abuse. Also, provide intuitive controls for managing this data without complicating the user experience.

Example: Instead of storing sensitive user information on company servers, encrypt it locally on the user’s device and give them full control over it.

6. Ethical Data Monetization

User data is valuable, but it shouldn’t come at the cost of privacy. Instead of exploiting personal information, businesses should explore ethical, transparent, and privacy-respecting ways to generate revenue.

Example: Generate revenue through subscriptions or other ethical business models rather than surveillance-based advertising.

7. Create Sustainable Privacy Practices

Regularly update privacy policies and practices to adapt to technological advancements and new regulatory requirements.

Example: Conduct periodic reviews of privacy policies and integrate new technologies like zero-knowledge proofs where applicable.

8. Be Accountable

Establish clear accountability measures through regular audits and transparent reporting of data practices to users.

Example: Announce quarterly privacy audits or provide links to independent third-party reports on data handling practices.

Embracing Privacy as a Value Prop

Beyond adopting these principles, it’s important to use privacy as a value prop. It forces you to align your entire company with an ethical promise and lays the foundations for an open and honest relationship with your customers. For example:

  • If you prioritize user autonomy, even if it means giving back control over data collection, you’re demonstrating that user choice is a core value.
  • If you choose not to monetize personal data (even through optional subscriptions or donations), you’re positioning yourself as a values-aligned company.

This alignment ensures that your product isn’t just a tool for managing privacy — it’s a way to be upfront and honest about how you treat data, which builds trust over time.

Furthermore, our own research found an overwhelming majority of people were valuing digital privacy and security more and more each year and were willing to pay for it. Here’s a question from our most recent survey:

A graph representing a majority of users perceive the importance of digital privacy and security over the past few years as “becoming much more important”
Over 60% of people told us they perceive the importance of digital privacy and security as becoming “much more important”.

The Future of Privacy-First Design

Privacy-first design isn’t a trend — it’s the future. As regulatory pressure increases and users become more aware of how their data is being used, companies that prioritize privacy will gain a competitive edge. But beyond compliance and business incentives, designing for privacy is simply the right thing to do.

It’s time for designers to take responsibility for how technology shapes people’s lives.

Privacy should never be a luxury. It should be the default.
