Ophel requests only the permissions it needs to operate. Required permissions are declared in the extension manifest and granted when you install Ophel. Optional permissions are never granted silently — your browser asks you the first time a feature that needs one is activated, and you can revoke any of them later from Settings → Permissions.

​
Required permissions

These permissions are always active. Ophel cannot function without them.

​
Optional permissions

These permissions are off by default. Ophel requests each one through a browser prompt the first time you use a feature that depends on it.

​
Granting a permission

You do not need to grant optional permissions manually in advance. When you turn on a feature that requires one — for example, enabling WebDAV sync or the completion notification — your browser displays a standard permission prompt. Click Allow to grant it.
If you dismissed a browser permission prompt by accident, go to Settings → Permissions and use the grant controls there to trigger it again.

​
Revoking a permission

Go to Settings → Permissions. Each optional permission has a Revoke button. After you revoke a permission, any features that depend on it are automatically disabled — you do not need to turn them off individually.
Revoking <all_urls> disables both WebDAV sync and watermark removal at the same time, because both features depend on broad host access. If you only want to disable one of them, turn it off in its own feature settings instead of revoking the permission.

​
Site Extension host access

Site Extensions use optional host permissions for each pack origin, not a permanent blanket host grant at install time. When you install a pack or bind a custom HTTPS origin, the browser asks for access to those origins only. Denying the prompt rolls back that install or binding. See Install and manage Site Extensions for the full permission, reauthorization, and custom-origin flow. Granting Advanced Features Access (<all_urls>) also covers the origins of installed Site Extensions, so packs and custom bindings can activate without per-origin prompts. Revoking it returns those origins to per-origin prompts; Site Extensions are not disabled.

Frequently asked questions

WebDAV servers can be hosted at any URL — there is no fixed hostname Ophel can request permission for in advance. The <all_urls> permission allows Ophel to make a network request to whatever server address you configure. The request goes only to your own WebDAV server.
The cookies permission lets Ophel read session cookies on Claude’s domain so you can store and switch between multiple Claude accounts (Claude Session Keys). Ophel does not read cookies on any other site.
Yes. All optional permissions are off by default. Core features — conversation organization, prompt library, outline panel, themes, and local backup/restore — work without any optional permission.
