Essential

Session cookies and security tokens keep you signed in, protect access to your projects, and let you complete payments.

Analytics

We measure page visits, product actions and performance to understand which features people use and where a flow fails. Umami and Vercel Web Analytics are cookieless. Google Analytics uses cookies. PostHog uses cookies and browser storage for product analytics and session replay.

Session replay is limited to public marketing and authentication pages. Inputs are masked. Uploads, projects, results, dashboards, reports, account pages and shared projects are excluded. Product events contain a redacted page category, never your email, name, filenames, cell values, findings or report text. After sign-in, PostHog uses your account UUID to connect activity across sessions.

Analytics is enabled by default for all visitors. Previously saved choices from the retired cookie banner no longer control analytics. You can block cookies or tracking requests using your browser settings or a browser extension. Processors: Umami, Vercel Web Analytics, Vercel Speed Insights, Google Analytics and PostHog (product analytics and public-page session replay).

Reliability

Sentry and PostHog receives scrubbed error diagnostics. PostHog also receives anonymous Stripe lifecycle notices to help us operate and repair the service. Server monitoring does not use browser cookies.

Marketing

We do not use advertising cookies. Marketing email preferences are separate from website analytics and can be changed in your account.
