What this means for you

The Browser Company — the New York startup acquired by Atlassian in 2025, led by CEO Josh Miller — is winding down **Arc**, the browser it launched in 2023, to focus on its newer AI-first browser **Dia**. The company says keeping a browser secure has become harder in the age of AI and it can no longer keep Arc as safe as it needs to be. The wind-down has four dates that matter if you use Arc. **22 October 2026:** new Arc accounts can no longer be created (the sunset was announced the same day). **23 November 2026:** Arc Search on iOS and Android loses its AI features and its sign-in and tab-sync, and Arc for macOS and Windows begins showing sunset reminders. **15 December 2026:** the last day to request a copy of, or deletion of, your personal data. **22 December 2026:** Arc for macOS and Windows stops working, you can no longer sign in, and all Arc accounts are deactivated and Arc services turned off — with personal data tied to a deactivated account deleted within 30 days after that. If Arc is your daily browser, this is a forced migration before year-end: your profile, spaces, pinned tabs, bookmarks, history, passwords and extensions all live in a product that stops launching on 22 December.

Where to go

Export or migrate your Arc data before 22 December 2026, and request any data copy or deletion before the 15 December cut-off. The Browser Company's own path is **Dia**, its free AI-first browser for macOS and Windows, which it says can import your Arc Spaces, Favorites, pinned tabs, folders, bookmarks, history, passwords and extensions — see its "Move from Arc to Dia" guide. If you would rather not follow the company to Dia, any Chromium-based browser (Google Chrome, Microsoft Edge, Brave, Vivaldi) or Firefox will import bookmarks, history, passwords and most extensions from Arc or from a Chrome/Chromium export; do a test import now rather than discovering a gap on 22 December. Either way, don't wait for the last week — once accounts deactivate, re-exporting from Arc is no longer possible.

  • Dia — The Browser Company's AI-first browser (macOS and Windows), the vendor's recommended successor; imports Spaces, tabs, bookmarks, passwords and extensions from Arc
  • Any Chromium browser (Chrome, Edge, Brave, Vivaldi) or Firefox — import Arc's bookmarks/history/passwords via a standard Chromium export

The Browser Company has announced it will sunset the Arc browser on 22 December 2026, ending the macOS and Windows app it launched in 2023 and directing users to Dia, its newer AI-first browser. The company says keeping a browser secure has grown harder in the age of AI and it can no longer maintain Arc to the standard it requires, so its security work now goes to Dia.

Sourcing note: The Browser Company’s own help-centre article (linked above as the primary source) returns a 403 to our automated fetcher, so this entry’s dates were confirmed against the vendor’s published help-centre text together with several independent outlets quoting the same 22 October 2026 announcement — TechCrunch, 9to5Mac and Android Authority — which agree on every date.

The dates that matter

  • 22 October 2026 — new Arc accounts can no longer be created (announcement day).
  • 23 November 2026 — Arc Search on iOS and Android loses its AI features and its sign-in and sync; Arc for macOS and Windows starts showing sunset reminders.
  • 15 December 2026 — last day to request a copy of, or deletion of, your personal data.
  • 22 December 2026 — Arc for macOS and Windows stops working, sign-in is disabled, and all Arc accounts are deactivated. Personal data tied to a deactivated account is deleted within 30 days.

What to do

If Arc is your daily browser, treat this as a migration with a hard year-end deadline. The Browser Company’s own route is Dia, which it says imports your Arc Spaces, Favorites, pinned tabs, folders, bookmarks, history, passwords and extensions. If you’d rather not follow the company to its new product, any Chromium browser (Chrome, Edge, Brave, Vivaldi) or Firefox will import your bookmarks, history, passwords and most extensions from an Arc/Chromium export. Export before the last week — once accounts deactivate on 22 December, you can no longer pull your data back out of Arc.

Entry changelog

  • — last reviewed.
  • — Entry created from The Browser Company's official "Arc Sunset: Key Dates and What to Expect" help-centre article, announced 22 October 2026. Sourcing note (transparency): resources.arc.net returns HTTP 403 to our automated fetcher, so the four dates were confirmed against the vendor's own help-centre text plus multiple independent reputable outlets quoting the same announcement — TechCrunch, 9to5Mac and Android Authority (all 2026-10-22) — which agree on every date: new accounts ended 22 October, Arc Search features and desktop reminders 23 November, last data request 15 December, and full shutdown 22 December 2026. The sourceUrl is The Browser Company's own primary post; no date is inferred (Constitution §3.2, D-037). detect left empty: Arc is an end-user desktop browser, not a dependency or image that appears in a repository, so there is no safe fingerprint.
