Coming Early 2026: Your private link storage app

Dùn

Some things don’t belong everywhere. Keep personal links separate from your browser & protected by Face ID.

An orange iPhone floats over a blue background and its screen features the app. The app is a list of links, from how to get out of debt to health insurance themes.

Create a clear boundary between everyday browsing and personal interests.

Some links don’t belong in your browser

Browsers are great at remembering everything — sometimes too great. Dùn gives you a separate space for links you don’t want mixed with work tabs, suggestions, or shared devices. Nothing hidden. Just intentionally placed elsewhere.

Protected by Face ID. Stored on your device.

Private by design

Dùn is built around discretion. Your links stay protected behind Face ID or Touch ID, with no accounts, no tracking, and no feeds. What you save is yours — and only yours.

An iPhone displaying the Vault Locked screen. A colorful purple background on the iPhone's screen presents a lock icon, the vault locked title and the phrase: Unlock with Face ID to access your links.

Zoomed in view of an iPhone. The same main list of links is shown but this time there are colored filters at the top: Finances, Later and Personal. These are attached to links below.

Tags, no algorithms or distractions.

Organize without noise

Add context to your links with tags so you remember why you saved them. Dùn stays intentionally quiet — no recommendations, no rankings, no resurfacing things at the wrong time.

Free to start. Upgrade when it becomes essential.

A locker that grows with you

Dùn is free for up to 50 links — enough to see if it fits your life. When you’re ready to store more, a simple upgrade lets your locker grow, without changing how the app treats your data.

Why Dùn exists

I wrote about the small anxieties that led to Dùn — and why separation matters more than hiding.

Built with intention

Dùn doesn’t track you, rank your data, or try to be clever. It’s designed to stay out of the way and give you control over what belongs where.

Thank you

Your interest means a lot to me. I'm a sole developer working on this app on my spare time but I will try to get back to you ASAP!
