Permissions
Tab Bard asks for up to four permissions, since not every browser has favicon. What they read stays on your device: it has no servers and makes no network requests.
Why does my browser say it can read my browsing history?
Your browser may show “Read your browsing history” for the tabs permission, because the titles and URLs of your Tabs show where you've been. Tab Bard needs them to draw your Tabs.
It doesn't ask for the separate history permission, so it can't read your past browsing, only the Tabs you have open.
What each one is for
tabsRead your browsing history. Reads each Tab's title and URL, to show your cards, search them, and find duplicates.tabGroupsView and manage your tab groups. Reads your Groups and changes them when you ask: names, colors, collapsing, and moves.faviconRead the icons of the websites you visit. Shows each Tab's icon, from the browser's own cache. Without this permission, the icon comes with the Tab's details fromtabs.storageNo warning. Saves your settings, your Window names, colors, and order, and when Tabs were opened.
The warnings are the browser's own wording, so yours may put them differently. Some say “Access browser tabs” for tabs.
What happens to your data
Tab Bard has no accounts or analytics, and it doesn't transmit, sell, or share anything.
To recognize your Windows and Tabs after the browser restarts, it saves their URLs in the browser's local extension storage. It deletes a closed Window's entry after 30 days, and removing Tab Bard deletes everything it stored.
It doesn't run in incognito or private Windows. The privacy policy has the rest.
