Know what you’re getting.
Is this a full security or SEO audit?
No. LaunchCheck checks one HTML response and a limited set of headers. It does not execute JavaScript, crawl your website, exploit vulnerabilities, measure Core Web Vitals or certify legal/accessibility compliance. The score is the percentage of checks passed, not a ranking or safety guarantee.
What if my site renders everything with JavaScript?
The report sees only server-delivered HTML. Client-rendered content may be absent, so findings can require manual review. Use the free preview before buying.
How does payment work?
Pay native USDC on Base directly to the displayed merchant address. We verify the exact transfer and wait for chain finality before unlocking the saved report. No token allowance or wallet custody is requested. A payment can unlock only one order.
What data is stored?
We store your page URL, derived findings, report time and payment record. We do not store full fetched HTML. The secret in your recovery link controls report access; anyone with it can view your purchased report. Treat it like a password. Avoid submitting private or sensitive URLs.
Who sells the report, and where can I get help?
Merchant setup is pending. Payments are disabled; free audits and sample reports are available.
