In one line

1SO is a single-purpose browser extension: type one query and open the result pages of several search and AI engines at once. It does not collect, store, sell, or transmit any personal data. There is no account system, no analytics, and no server of our own.

How data is handled

DataHandling
Search queryUsed only to build the URLs of the engines you selected. Sent directly from your browser to those engines — never to us. The last query may be kept locally as a convenience.
SettingsTheme, language, selected engines, saved combos, custom engines — stored in chrome.storage.sync / chrome.storage.local under your own browser profile.
Selected textRead only when you explicitly trigger search-on-selection (right-click or keyboard shortcut), used immediately to build the URL, and never persisted.
Page elements on AI sitesOn the AI chat sites declared in the manifest, a content script locates the question input box to pre-fill your query and show a follow-up bar. This happens entirely inside your browser: nothing beyond locating the input is read, nothing is recorded, nothing is transmitted.
Engine tableThe extension periodically fetches a public JSON list of engine URLs from our website. It contains no user data and is used only to fix engine URLs without shipping a new version.

What it never does

Permissions and why

PermissionWhy
activeTabAccess the current tab after a user gesture (icon click / context menu) to read selected text.
tabsCreate the result tabs; let the side panel list tab titles and URLs.
tabGroupsGroup the tabs produced by one search into a single colored tab group.
sidePanelShow the vertical tab overview next to the page after a search.
contextMenusAdd the right-click search entry for selected text.
storageSave your settings locally or through your browser sync.
scriptingRead the current selection when you press the search-selection shortcut.
notificationsShow a local system notification when a search completes or fails.
system.displayIn optional side-by-side window mode, lay result windows out across your screen.

The extension declares no host permissions. Content scripts run only on the fixed list of AI chat sites declared in the manifest, solely for the pre-fill and follow-up features described above.
