ARC Tab is built to be private by default. Everything you create — your sections, links, notes, tasks, and anything you place on your tab — is stored only on your device and is never sent to any server run by ARC Tab. ARC Tab has no backend database and keeps no copy of your data.

A small number of features are opt-in and only reach the network when you choose to use them (feeds and buying Pro). Those are described explicitly below. When you don't use them, ARC Tab makes no outbound network requests at all.

In one line: ARC Tab collects nothing, transmits nothing to us, and has nowhere to transmit it to.

What ARC Tab stores on your device

ARC Tab stores only the data you create:

• Your sections and links (titles, URLs, optional notes, and per-item settings such as hidden/collapsed state).
• Your widgets and their contents — to-do items, notes, Pomodoro settings, quick links, the address of any feed you added, and saved AI-chat links.
• Your workspaces and, if you use them, the schedule rules that switch between them by day and time.
• Anything you place on the tab canvas: sticky notes, text, drawings, and images. Images you upload from your device are kept in a separate device-local slot and, like your licence, are never included in an export (see below).
• Your preferences (theme, appearance, accent colour, density, display name, and toggles for the greeting, search, and link-opening behaviour).
• Onboarding progress (so it doesn't show again).
• If you buy Pro, a licence record for this device (see below).

This data is saved locally using the browser's extension storage (chrome.storage.local, with a localStorage fallback). It stays on your computer. ARC Tab does not use chrome.storage.sync, so nothing is copied to your Google account.

What ARC Tab does not do

• No servers of our own. ARC Tab has no backend and no database. There is no ARC Tab account to create and nothing to sign in to.
• No tracking or analytics. ARC Tab contains no telemetry, analytics, ad SDKs, or third-party tracking scripts.
• No browsing-history or bookmarks access. ARC Tab does not read your history, bookmarks, or the content of the pages you visit.
• No favicon fetching. Around 110 brand icons ship inside the extension, so saving a link never tells a third party which sites you use.
• No content scripts. ARC Tab never injects code into the pages you browse.
