StealthStack is a search index for agent resources. This page explains, in plain terms, what we collect, why, and how long we keep it.
What we collect
Requests and visits. When you use our website, search API or MCP server, we log basic request details, such as what was requested, when, the referring page, the country and network Cloudflare reports, and the kind of browser or client. We also count page visits. We keep these logs to run and protect the service and to understand how it's used.
Searches. We store search text as you typed it, for up to 180 days. Please keep personal information and secrets out of searches.
IP addresses. We use IP addresses to keep the service safe, to spot fake search-engine crawlers and to count visits. We don't keep them in a readable form, apart from short-term backups and logs that are deleted within 30 days.
File conversions. Files you convert are deleted when the conversion finishes, and we never keep their contents.
Conformance checks. To check a domain, we fetch its public ARD catalog. Results are shown on the public scoreboard only for domains already in our index.
Publishers. We index public ARD catalogs as their publishers list them. Our crawler also reads other public registries.
How long we keep it
- Search text: up to 180 days.
- Request logs: kept to run and protect the service and to understand usage.
- Backups: deleted within 30 days.
Third parties
- Cloudflare hosts our website, API and data. Cloudflare Web Analytics counts page views, and Cloudflare says it uses no cookies.
- Our pages load fonts from Google Fonts, so your browser contacts Google.
- GitHub runs our crawler and scheduled jobs, and holds short-term backups.
Cookies
We don't use tracking or advertising cookies. Cloudflare may set a strictly necessary security cookie.
What we don't do
We have no accounts and no ads, and we don't sell data.
