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 Portland's best brunch spots to health insurance plans and quotes.

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 Dùn is Locked screen. A colorful purple background on the iPhone's screen presents a lock icon, the safe 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 it's filtered by a tag that says Shopping. The same tag is attached to links below talking about gifts for grown-ups and affordable running shows.

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 space 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 vault 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.
