Privacy Policy

What Layer8 Is

Layer8 is a Chrome extension that lets you draw on web pages. Your drawings are stored on our servers so other Layer8 users can see them when they visit the same page.

Data We Collect

Drawing data

When you draw on a page, we store the stroke data (coordinates, color, brush size) and the normalized URL of the page. We do not store screenshots, page content, or any information about the page itself beyond its URL.

Account data

If you sign in, we store your email address and a display name via our authentication provider (Clerk). You can use Layer8 without signing in — anonymous drawings are associated with a random device identifier stored locally in your browser.

Device identifier

A random UUID is generated on install and stored locally in your browser via chrome.storage.local. This lets us associate anonymous drawings with your browser session. It is never shared with third parties and can be reset by reinstalling the extension.

Data We Do NOT Collect

• Browsing history or pages you visit (we only know about pages you draw on)
• Page content, text, or screenshots
• Cookies from other sites
• Keystrokes or form inputs
• Location data
• Personal files or system information

How We Use Your Data

• To display your drawings to other Layer8 users on the same page
• To restore your drawings when you revisit a page
• To associate drawings with your account (if signed in)

We do not sell, share, or monetize your data in any way. We do not run ads. We do not use analytics or tracking scripts in the extension.

The Layer8 website (layer8.art) uses AWS CloudWatch RUM to monitor page performance and errors. This collects anonymized metrics (page load times, JS errors, HTTP request timings) and is limited to the marketing site only — it is not present in the extension.

Third-Party Services

• Clerk — Authentication provider. Handles sign-in/sign-up. Subject to Clerk's privacy policy.
• Neon — Database hosting (PostgreSQL). Stroke data is stored here. Subject to Neon's privacy policy.
• AWS — API hosting (Lambda, API Gateway). Requests are processed here. Subject to AWS's privacy policy.
• AWS CloudWatch RUM — Website performance monitoring on layer8.art only (not the extension). Collects anonymized page load, error, and HTTP metrics. Subject to AWS's privacy policy.

Data Retention

Drawings are stored indefinitely unless you delete them or your account. To request data deletion, email privacy@layer8.art.

Your Rights

You can:

• Use Layer8 without creating an account
• Request a copy of your data
• Request deletion of your data and account
• Uninstall the extension at any time (local data is deleted immediately)

Changes to This Policy

If we make material changes, we'll update the date at the top and notify users through the extension or this page.
