Privacy Policy

What stays on your device

Unsigned drawings live only in the active editor tab unless you export them. Signed-in cloud save uses your SVG Lab account instead of browser-persistent storage. Concretely:

• Your unsigned drawings are not saved after refresh or close. Export the file or sign in for cloud save before leaving.
• Your editor preferences (such as colour swatches and magnetic snap) are kept in memory for the current tab only.

What we collect

To understand whether the editor is useful and to catch bugs, we send a small amount of anonymous usage data to three privacy-respecting services. None of it includes the drawings you make.

• Cloudflare Web Analytics — cookieless page-view metrics: which page was visited, the referring URL, your country (not city or IP), browser family, and Core Web Vitals (how fast the page loaded for you). This is used to measure traffic and performance. Cloudflare's product specifically does not use cookies and does not fingerprint individual visitors. More info.
• PostHog — product analytics that capture page views, the page you came from, your country, your browser, and the time you arrived/left. SVG Lab configures PostHog with memory-only persistence, so analytics state is not kept across browser restarts by SVG Lab. PostHog session recording is disabled. PostHog privacy policy.
• Sentry — receives a copy of any JavaScript error that the editor throws, plus the surrounding browser context (URL, browser version, the last few user actions in the app). This is how we find and fix bugs. If you submit feedback via the in-app feedback widget, that message is sent to the same Sentry inbox. Sentry privacy policy.
• Standard request data — your IP address, browser version, and the page you requested — is briefly seen by Cloudflare, our hosting provider, the same way every website on Cloudflare does. Cloudflare uses this for delivering the page and for DDoS protection.

What we don't collect

• No traditional advertising cookies.
• No advertising pixels, no behavioural retargeting, no fingerprinting beyond the anonymous browser-session identifier described above.
• No cross-site tracking — the analytics above only see what happens on svglab.app.
• No copy of your drawings on our servers — there are no servers that store user content yet.
• No session replay or screen recording.

Opting out

If you'd rather not be counted at all, you have a few options:

• Turn on Do Not Track in your browser. Cloudflare Web Analytics honours it automatically.
• Use a privacy-focused browser extension like uBlock Origin or Privacy Badger to block the analytics endpoints.
• Run the editor from a local copy: clone the repository and open index.html from your filesystem — none of the analytics fire from file:// or localhost.

What changes when accounts arrive

In the future, we plan to add optional sign-up via Google or magic-link email so you can sync your work across devices. When that ships:

• Sign-up will always be optional. The editor itself stays free and usable without an account.
• If you sign up, we'll store your email address, your account ID, and the project files you choose to save to the cloud.
• This policy will be updated and dated before that goes live.

Third-party services we use

• Cloudflare hosts the site, provides DNS, the CDN, DDoS protection, and the cookieless analytics described above. Their privacy policy is at cloudflare.com/privacypolicy.
• PostHog provides the product-analytics described above. We use the EU/US Cloud service. Their privacy policy is at posthog.com/privacy.
• Sentry provides the error-monitoring described above. Their privacy policy is at sentry.io/privacy.

Your rights

Because we don't store personal information on our servers in the current browser-only version, there's nothing of yours to access, correct, or delete. Clearing your browser's site data for svglab.app removes everything SVG Lab put there.

Children

SVG Lab is a general-purpose creative tool with no targeted features for children, no advertising, and no data collection. It's safe for any age.

Changes to this policy

If we change what's collected, this page will be updated and the date at the top will be revised. Significant changes will also be flagged in the editor itself.
