We’ve decided to sunset Arc on December 22, 2026

That’s not an easy sentence to write. We spent years building Arc and celebrating each and every release along the way: we have so much pride and love for what we made alongside the Arc community.

Our priority is to deliver best-in-class security for our members. Keeping a browser secure takes constant, dedicated work that is only increasing in the age of AI. Dia was built from the ground up to meet today’s security standards, so that’s where our engineering and security teams will focus moving forward.

We’ve worked to make switching to Dia as easy as possible for Arc members. Here’s how:

Your passwords, bookmarks, extensions and history come over to Dia seamlessly.
Spaces, Folders, and Tab Groups are in Dia and import over with your data intact.
Dia now surpasses Arc benchmarks in stability, speed, and security.

The browser features you use in Arc are free in Dia, and the AI is optional.

Thank you for using Arc, for pushing us to make it better, and for building alongside us. The team that made Arc is the same team behind Dia, and some of our most ambitious work is just ahead. We’d love for you to be there with us when it lands.

New Arc accounts can no longer be created. For existing Arc members, nothing will change yet. The latest version of Arc adds an option to export all of your data out of Arc, and an even smoother import into Dia.
November 23
On iOS and Android, Browse for Me and other AI features will be disabled. Arc Search will continue working as a browser, but you will no longer be able to sign in or sync your tabs.
December 22
You will no longer be able to access or use Arc on macOS or Windows. Arc accounts will be deactivated, with their personal data deleted within 30 days. Arc Search for Android will be pulled from the Google Play Store.

Moving to Dia is easy

Import from Arc, and your setup comes with you.

Your Spaces are now Profiles

They come over to Dia with all your info. Use profiles for work, personal browsing, and everything in between. Swipe between them to switch contexts just like in Arc.

Keep your tabs in the Sidebar

Choose Sidebar tabs for the familiar vertical layout. Keep your tabs close by, or hide the sidebar with /Ctrl+S when you need to focus.

Bring your Pinned Tabs and Favorites

They come over from Arc when you import, with their custom names intact. Your everyday sites stay easy to reach.

Folders come along, too

They import seamlessly, now called Tab Groups in Dia.

Questions

Arc for macOS and Windows will remain available until December 22, 2026. Until then, Arc will continue to work as usual and will receive basic updates.

On December 22, 2026, Arc for macOS and Windows will stop working, and you will no longer be able to sign in to your Arc account.

As of October 22, 2026, new Arc accounts can no longer be created. Existing accounts are not affected by this change.

Dia is replacing Arc. It’s the new browser from the team that built Arc, and it keeps the Arc features you rely on, like vertical tabs in the Sidebar, Spaces (now called Profiles), Pinned Tabs, Folders, and Split View. You can bring your Arc data (passwords, extensions, profiles, tabs) over in a few clicks, and Dia is free to download for macOS and Windows at diabrowser.com.

Yes, in just a few clicks during sign up. Download Dia, and when it asks which browser to import from, select Arc. Dia brings over your passwords, history, tabs, Profiles, Folders, bookmarks, and extensions, on both macOS and Windows.

Already using Dia? You can import from Arc at any time before December 22, 2026. On macOS, go to Dia > Import from Another Browser from the Mac menu bar. On Windows, open the Dia app menu and select Import from another browser.

Yes. If you’re moving to Dia, you don’t need to export anything first, because Dia brings your logins, extensions, Spaces, Favorites, Pinned Tabs and Folders straight over from Arc.

If you’d like to use your tabs in another browser, you can save them as a list of links before December 22, 2026.

On macOS

Go to Arc > Settings in the Mac menu bar.
Select Advanced, then Export Data.
Choose where to save the file, then select Save.

On Windows

Open Arc’s settings: press Ctrl+,, or open the Arc menu and select Settings.
In the Advanced section, find Export Spaces and tabs and select Export Data.
Choose where to save the file, then select Save.

Haven’t opened Arc in a while? You can still export your data before December 22. Download Arc again using the link for your computer, then export your data from inside the app.

On iOS (Arc Search)

Tap the Tab Switcher icon in the bottom-left corner, tap Settings, then tap Export Data to share or copy a list of your open tabs.

On Android (Arc Search)

Tap the Tab Switcher (the stacked tabs button) in the bottom-left corner, tap Settings (⚙️), tap Storage, then tap Export data to share or copy a list of your open tabs.

We will deactivate all Arc accounts on December 22, 2026. Once an Arc account is deactivated, personal data related to the account is deleted within 30 days.

If you have an account for both Dia and Arc, this will only affect personal data related to your Arc account.

As of December 22, 2026, we will no longer be able to identify or retrieve Arc user data for data requests. To keep your data, export it from Arc or import it into Dia before December 22, 2026. For instructions, see the FAQs “Can I export my tabs out of Arc?” and “Can I import Arc data into Dia?”.

Dia is made by the team that made Arc, and it’s where all of our focus is going, including our whole security team.

Give Dia a try.
