Loom Recordings Are Permanent Artifacts

Live screen sharing is risky because it broadcasts your screen in real time. Loom is riskier because the broadcast is permanent. When you record a Loom, you create a video file that can be viewed, rewound, paused, scrutinised, and shared with anyone who has the link. A fleeting moment of accidental exposure during a live call might be missed. In a Loom recording, it is preserved forever.

Over 25 million people use Loom. The tool has become the default for async communication in remote teams: product demos, bug reports, internal updates, client walkthroughs. But the same features that make Loom powerful -- easy recording, instant sharing, automatic transcription -- also make it a significant privacy risk if you record without preparation.

This guide covers how to protect sensitive information when recording with Loom, what Loom's built-in privacy features do and do not cover, and how to fill the gaps.

What Loom Offers Natively

Recording modes. Loom lets you record your full screen, a specific window, or a specific Chrome tab (via the extension). Tab recording is the most private option because it excludes everything outside that single tab. Window recording excludes your desktop and other applications. Full screen recording exposes everything.

Drawing tools. Loom includes on-screen drawing tools during recording. You can use these to highlight content, but they are not designed for hiding content. Drawing over sensitive data is not reliable because it does not persist consistently and cannot cover dynamic content.

Video trimming. After recording, Loom lets you trim the beginning and end of the video. This helps if you accidentally showed something before or after your intended content, but it does not help with sensitive data visible during the middle of the recording.

Link privacy settings. Loom recordings can be set to "Anyone with the link," "Workspace only," or "Only specific people." This controls who can view the recording but does not protect the content within it. If sensitive data is visible in the recording, the privacy setting only limits who sees it, not whether it exists.

Password protection. Loom Pro and Business plans allow password-protecting recordings. Same limitation as link privacy: it restricts access but does not redact content.

Transcription and AI summaries. Loom automatically transcribes recordings and generates AI summaries. If you speak sensitive information aloud (names, account numbers, internal project details), it appears in the text transcript and the AI summary, both of which are separately searchable and shareable.

What Loom Does NOT Offer

No content blur or redaction. Loom has no built-in feature for blurring or redacting parts of your screen. You cannot select an element and hide it from the recording. This is the most significant privacy gap.

No post-recording redaction. Once a Loom is recorded, you cannot edit the video to blur sensitive content. Your options are to delete the recording and re-record it, or to leave it as-is. There is no video editor for redacting specific areas or time ranges.

No notification suppression. Loom does not suppress system notifications during recording. If a Slack message, email preview, or calendar alert appears while you are recording, it is captured in the video. Unlike live screen sharing where a notification vanishes in seconds, a Loom notification is permanent and replayable.

No auto-DND. Loom does not activate Do Not Disturb on your system when recording starts. You must configure this manually. Check our guide on hiding notifications during screen sharing for the shortcuts on every OS.

The Loom Privacy Problem

The combination of these gaps creates a specific problem: Loom makes it extraordinarily easy to create a permanent, shareable, searchable recording that contains sensitive data you did not intend to include.

Consider the typical Loom workflow. You click record, walk through your screen, click stop, and share the link. The entire process takes two minutes. There is no review step built into the workflow. There is no "are you sure?" prompt that checks for sensitive data. The speed that makes Loom valuable is the same speed that makes it dangerous.

And because Loom recordings persist, the exposure is not limited to the moment of recording. A recording created six months ago with a visible API key, a client name in a sidebar, or an employee salary on a dashboard remains accessible until someone notices and deletes it.

How to Protect Sensitive Data in Loom Recordings

Method 1: Record a Tab, Not Your Screen

Always choose "Current Tab" recording mode in the Loom Chrome extension. This captures only the content of a single browser tab. Your desktop, taskbar, other applications, other tabs, and even the rest of your browser window are excluded.

Tab recording is the single most effective privacy measure for Loom. It eliminates entire categories of accidental exposure: notifications, background apps, desktop icons, and the personal information that lives on your desktop.

Method 2: Blur Sensitive Elements Before Recording

Before you click record, blur any sensitive data visible in the tab you are about to share. CRM sidebars, data tables, name fields, email addresses, account numbers -- anything that should not be in a permanent recording.

ContextBlur works before and during Loom recordings because it operates at the browser DOM level. Blur the elements, then start your Loom. The blurred elements remain blurred throughout the recording. When you stop recording and want to resume normal work, remove the blurs.

If you have auto-blur rules configured for the domain you are recording, they apply automatically. This is particularly valuable for recurring Loom workflows: if you regularly record walkthroughs of a CRM or analytics dashboard, set up the blur rules once and they apply every time.

Method 3: Enable System DND Before Recording

Open the Loom extension. Before clicking record, enable Do Not Disturb at the OS level.

macOS: Hold Option and click the date/time in the menu bar. Windows 11: Win+N to open notifications, toggle DND. Windows 10: Click the notification icon, select Focus Assist, then Alarms Only.

This prevents notifications from appearing in your recording. Make it a reflex: DND first, then record.

Method 4: Use a Clean Browser Profile

If your Loom recordings show browser content, switch to a presentation browser profile before recording. A profile with no personal bookmarks, no sensitive browsing history, and no autofill data eliminates the risk of exposing personal context through your browser chrome.

Method 5: Review Before Sharing

Loom makes it easy to share immediately after recording. Resist this urge for any recording that might contain sensitive data. Watch the recording back at 2x speed. Check for:

• Visible notifications that slipped through
• Sidebar data from other clients or projects
• URL bar suggestions that appeared during navigation
• Tab titles from other open tabs (if you used window recording)
• Spoken information captured in the transcript

If you find an issue, delete the recording and re-record. There is no editing option.

Loom-Specific Privacy Settings

Workspace-Level Controls (Loom Business)

Loom Business plans offer workspace-level settings that administrators should configure:

• Default recording privacy: Set to "Workspace only" to prevent recordings from being publicly accessible by default.
• Download permissions: Restrict who can download recordings. Downloaded recordings are outside Loom's access controls.
• Transcript visibility: Consider whether transcripts should be visible to all viewers or restricted.
• Retention policies: Set automatic deletion timelines for old recordings to limit the persistence of exposed data.

Individual Recording Settings

For each recording, verify:

• Access level is appropriate (public link vs workspace vs specific people)
• Comments are limited to appropriate audiences
• Password protection is enabled for sensitive content

Loom vs Live Screen Sharing: The Privacy Comparison

The privacy risk profile of Loom is strictly higher than live screen sharing. Every risk that exists in live sharing also exists in Loom, plus the additional risks of permanence, searchability, and uncontrolled distribution.

The Recording Mindset

When you share your screen live, the moment passes. When you record a Loom, you create an artifact. The right mindset for Loom recording is closer to writing a document than having a conversation. You would not put a client's account number in a written report. Do not put it in a Loom recording.

The preparation takes the same thirty seconds as live screen sharing: DND on, clean browser profile, sensitive data blurred, tab recording mode selected. The difference is that for Loom, these thirty seconds protect you not just during the recording but for as long as that recording exists.

Record with intention. Blur what should not be seen. Review before sharing. Delete what should not persist.
