Privacy Policy
Last updated: 3 May 2026
What we collect
We collect the minimum data needed to run the service. For the free tier (anonymous URL checks): we never store your IP address. We salt-and-hash an IP prefix with the current hour for rate-limiting purposes only. The hash is one-way and discarded after one hour.
For paid accounts: we store your email address (used for sign-in via magic link, GitHub, or Google OAuth), your subscription details (handled by our payment processor Polar.sh), the URLs you choose to monitor, and the check results we generate over time.
Cookies and analytics
We use only strictly-necessary cookies by default (sign-in session, theme preference, consent choice). On first visit we ask you whether to enable analytics. If you opt in, we use self-hosted Umami analytics — no third-party cookies, no IP collection, no cross-site tracking.
Our analytics consent also enables session recording on a 15% sample: roughly 1 in 7 visits is recorded as an anonymized replay so we can spot UX issues we wouldn't otherwise notice. Recordings are stored on our self-hosted Umami instance, capped at 5 minutes per session, and use moderate masking — input fields, password fields, and elements marked sensitive on the page are obscured. We do not share recordings with third parties.
You can change your choice anytime via “Manage cookies” in the footer. Declining analytics turns off both page-view tracking and session recording entirely.
Transactional emails (magic links, alerts, billing) are sent via Resend from noreply@web-down.com. Replies go to our support inbox. We do not send marketing emails without explicit consent.
Third parties
Our processors are: Cloudflare (CDN/DNS), Hostinger (hosting), Convex (database), Polar.sh (payments and VAT), Resend (email), Anthropic (AI features for Pro tier only). All have GDPR-compliant DPAs in place.
Your rights
You can export, modify, or delete all your data from the account settings page. Account deletion is irreversible and removes all monitors, results, incidents, AI reports, and anomalies.
