Vimium C supports both export and cloud-based synchronization of your settings (including key mappings and search
engines). None of your browsing behavior is included.

By default, Vimium C only downloads synced settings during the first installation, and if no synced settings are found,
it will never sync with your browser account. However, if you do wish to enable this behavior, you may enable the
advanced `Synchronize settings with your current account for this browser` setting.

All information handled by Vimium C, including history, bookmarks, page titles and URLs, will only be used locally.

Your search history in `Vomnibar` and `Link Hints` modes will be purged immediately after use. Your keyword searches --
entered when using `FindMode` -- are stored but never included in synced settings. Please note that your `FindMode`
search keywords on Incognito windows are stored temporarily, and will remain in memory, until all of your Incognito
windows have been destroyed.


Permissions Required
====================

Vimium C requires these permissions:
* **`bookmarks` & `history`**: to match queries and generate suggestions for Vomnibar.
* **`tabs`**: to operate your tabs, including opening, removing, moving and updating.
* **`webNavigation`**: to match an incoming URL, confirming whether Vimium C should be enabled or disabled on the page.
* **clipboard read+write & browsing activity**: to add shortcuts for copying and pasting the page title/URL, link
text/href, and the like.
* **`contentSettings`**: to toggle your browser's content settings. For example, displaying your preferred typeface, or
a larger font size, on selected websites.
* **`notifications`**: to show a notification whenever Vimium C is upgraded.
* **`sessions`**: to allow you to restore closed tabs. This functionality requires Chrome 37+ or Firefox.
* **`storage`**: its syncing functionality is **not in use** by default. However, if you enable "`Sync settings with
your current account for this browser`", Vimium C will require **`storage.sync`**, to sync your settings items with
the browser account servers.

Note:
* The "**browsing activity**" listed above actually includes a number of separate permissions: `tabs`, `<all_urls>` and
`webNavigation`.
* Vimium C never deletes any browser history item, except on explicit user requests (such as <kbd>Shift+Delete</kbd>).
