Chrome permissions and why Trellus uses them
| Permission | When | What Trellus uses it for |
|---|---|---|
| Storage | Always | Keeps your Trellus settings and session state on your device between browser sessions. |
| Tabs | Always | Finds the supported CRM and dialer tabs you have open and passes messages between them and the Trellus panel. This permission lets an extension read the address of open tabs; Trellus uses it to find supported pages. |
| Alarms | Always | Schedules background tasks, such as retrying an extension update. |
| Display information | Always | Places the Trellus window correctly on your screen during calls. |
| Network rules | LinkedIn inbox only | Adjusts one request header for linkedin.com so the LinkedIn inbox can load your messages. It has no effect unless you allow Trellus on linkedin.com. |
| Offscreen documents | Asked when needed | Runs calling audio in a hidden Trellus page, so a call keeps going when you switch tabs. |
| Scripting | Asked when needed | Adds Trellus to sites you turn it on for, and restores it on open tabs after an update. |
| Cookies | LinkedIn inbox only | Uses your signed-in LinkedIn session so the LinkedIn inbox can load and send your LinkedIn messages. |
| Notifications | Asked when needed | Alerts you to an incoming Trellus call. |
Sites Trellus runs on
Preset when you install
Chrome shows these at install: Salesloft, Outreach, HubSpot, Apollo and Salesforce, plus the dialer pages Trellus has supported for coaching (Orum, PhoneBurner, Salesfinity, Dialpad, Kixie and RingCentral Embeddable).
Asked site by site
For any other site, such as Google Sheets, Attio, Close or GoHighLevel, Trellus asks Chrome for access to that site when you turn Trellus on there. You can review or remove that access at any time under Site access on the extension's details page.
Microphone and call audio
Trellus places calls from its own dialer in your browser. The first time, Chrome asks you to allow microphone access for the Trellus extension; without it, Trellus can't place calls. You can revoke it later in Chrome's site settings for the extension.
Call audio goes through Trellus's calling service to connect the call. Depending on your plan and team settings, Trellus also uses it for transcripts, call summaries, recording links and live coaching.
When Trellus coaches calls placed in another dialer, such as Aircall, Dialpad or RingCentral, it listens to that dialer's call audio in the browser tab rather than opening your microphone itself.
Turn Trellus off or limit it
- Pause it. Switch Trellus off on Chrome's Extensions page (chrome://extensions); nothing runs until you switch it back on.
- Limit sites. Under Details, then Site access, remove sites you no longer want Trellus to open on.
- Revoke the microphone. In Chrome's site settings for the Trellus extension, set Microphone to Block.
- Remove it. Choose Remove on the Extensions page to uninstall Trellus and its stored settings from this browser.

Frequently asked questions
Can Trellus read every website I visit?
No. Trellus runs on its preset CRM and dialer sites and on sites you turn it on for, and Chrome asks before Trellus gets access to any other site. You can review that access under Site access on the extension's details page.
Does Trellus need my microphone?
Yes, to place calls from the Trellus dialer. Chrome asks you to allow it the first time, and you can block it again in Chrome's site settings for the extension.
Does Trellus record calls?
Supported call activities can include a recording link, transcript and summary, depending on your plan and team settings. Ask your admin or contact us through the Support Center to check what your team has turned on.
