About the SINAL crawler
SINAL is a digital presence analyser. When someone pastes their website address into our tool, our server opens that page once and measures it — speed, meta tags, structured data, accessibility, conversion paths. We then hand the owner a report with the fix, ready to paste.
When we visit
Only when a human asks. We do not crawl the web, we do not follow links beyond the page we were given, and we do not build an index. One person, one address, one read.
What we respect
- ✓robots.txt — if you disallow us, we stop
- ✓one request per analysis, no crawling of your whole site
- ✓we identify ourselves in the User-Agent, always
- ✓we never store your page content, only the measurements

How to allow us
If you are the owner and want a complete reading, allow the user agent below in your firewall. Our requests are also signed with Web Bot Auth (Ed25519), so you can verify cryptographically that a request really came from us:
SINAL/1.0 (+https://getsinal.com/robo; analisador de presença digital)
Verify it is really us
Every request we make is signed with Ed25519 (Web Bot Auth). Fetch our public key and you can verify it cryptographically — no IP allowlist needed, and nobody can pretend to be us.
