Privacy Policy

Last updated: November 4, 2026

Complete OS LLC runs SiteGuard. This page says what we collect, why, who handles it and what you can do about it. We don't sell your data, we don't use it for advertising, and SiteGuard scans don't use AI.

What we collect, and why

• Your email address, to create your account, send sign-in links and send your reports.
• The websites you add or order an audit for, so we can scan them.
• Scan results: scores, the page addresses scanned, and for each issue the page address, the element and a short piece of that element's HTML. If a public page shows someone's personal details inside a flagged element, that snippet can end up in your report. We only scan pages a visitor can reach without signing in.
• Billing records: your Stripe customer and subscription IDs and subscription status. Stripe collects your card details; we never see or store them.
• Usage and error data: pages visited and approximate device and browser details through PostHog, error reports through Sentry, and normal server logs, including IP addresses, at our hosting provider. We use these to keep the site working and understand how it is used.

Who handles it

• Supabase stores the database and handles sign-in.
• Stripe takes payments and manages subscriptions.
• Resend delivers sign-in links and report emails.
• Vercel hosts the website.
• Fly.io runs the scanner.
• PostHog provides usage analytics.
• Sentry receives error reports.

These companies process data for us to run SiteGuard, and most of that processing happens in the United States. We may also share data if the law requires it, or with a buyer if the business is ever sold, in which case this policy keeps applying.

How long we keep it

We keep your account, sites and scan history while your account exists, including after you cancel, so your history is there if you come back. If you ask us to delete it, we remove it within 30 days. We keep payment records for as long as tax and accounting law requires, and analytics and error data follow those providers' retention periods.

Cookies and browser storage

We use a cookie to keep you signed in. PostHog uses a cookie or browser storage to recognize returning visitors. We don't use advertising cookies.

Your rights

You can ask for a copy of your data, a correction, a machine-readable export, or deletion of your account, by emailing hello@completeos.app. We will respond within 30 days. Depending on where you live, you may have further rights under local privacy law, and we won't treat you differently for using them.

Security and age

Data is encrypted in transit, and each account can read only its own records. No system is perfectly secure, and we will tell you if a breach affects your data as the law requires. SiteGuard is for people 18 and over, and we don't knowingly collect data from children.

Changes and contact

If this policy changes, we will update this page and its date, and email active customers about anything significant. Questions: Complete OS LLC, hello@completeos.app. The rules for using SiteGuard are in the Terms of Service.
