tileco privacy policy

Effective 24 October 2026.

tileco is a Chrome extension that tiles and arranges your Chrome and web app windows on chromeOS. This policy says what it reads, what it keeps, and where that goes.

In short: tileco has no server, no analytics and no ads. It sends nothing to its developer or to anyone else. What it keeps stays in Chrome’s own extension storage, on your Chromebook. The one exception is your settings, which Chrome Sync copies to your Google account if you have Sync turned on.

What tileco reads

• Your windows, through Chrome’s windows API: each window’s position, size and state, to tile your windows and put them on workspaces.
• Your tabs, only if you allow tab search in tileco’s settings: each tab’s title, address and site icon, through Chrome’s tabs permission. tileco uses them to find tabs in its launcher, put windows back where they were after Chrome restarts, and recognize Secure Shell’s windows.
• Your displays’ sizes, to lay out windows on each one.
• Page titles on sites you allow for unread counts: Gmail, Google Chat and Google Calendar to start with, and any others you add, each only once you allow it in tileco’s settings. On those sites a small script reports the page title whenever it changes. tileco reads only the unread count in the title, such as the 3 in “Inbox (3)”, to mark a window that needs your attention. It doesn’t read the page’s content.
• Nothing else from the pages you visit. If you turn on “Dim inactive windows”, tileco asks for access to all sites. It uses that access only to place a translucent overlay over windows you’re not using, and it reads nothing from those pages.

What tileco keeps, and where

• On your Chromebook, in chrome.storage.local:
  • which windows are on which workspace, and their layouts;
  • with tab search allowed, the addresses of up to 20 tabs per window, so windows can return to their workspaces after a restart;
  • the latest unread count for each tab on a site you allowed;
  • this Chromebook’s layout and mouse settings, the setup checklist’s ticks, and the mouse’s input device number from its mouse page.

  This data never leaves the Chromebook. Removing tileco deletes it.

• In your Chrome settings, in chrome.storage.sync:
  • your clocks and working hours;
  • the names and addresses of the sites on tileco’s app keys;
  • the sites in your unread counts list;
  • your workspace layout settings and how dark inactive windows are dimmed.

  If Chrome Sync is on, Chrome copies these to your Google account and your other signed-in browsers, as it does for any extension’s synced settings. That is Chrome’s service, covered by Google’s privacy policy. tileco has no access to your account beyond these settings. Removing tileco, or resetting its settings on its options page, deletes them.

What tileco sends

Nothing. tileco makes no network requests of its own. Showing a tab’s site icon in the launcher loads that icon the way Chrome’s own tab strip does.

Permissions

tileco asks for the first three when you install it. Chrome shows no warning for them. It asks for the rest only when you click Allow in its settings, and you can turn each off there again.

Permission	Why
system.display	Each display’s size, to lay out windows
storage	Keeping the state and settings above
scripting	The unread-count script on sites you allow, and the shade over inactive windows
tabs (optional)	Tab titles and addresses, for tab search, restarts and Secure Shell’s windows
Each site in your unread counts list (optional)	Its unread count, from the page title
All sites (optional)	Only for dimming inactive windows
