We build small free tools that do one thing well, without selling you out to third parties.
🛡 Try check.syviel.comMost "free" security tools exist to collect your data and pitch you a subscription by the second page. We do the opposite: tools you can use without an account, that never store what you give them, and that stay free for normal use. We're a small independent team, not a Silicon Valley unicorn — and we're perfectly fine with that.
Check in 10 seconds whether your email has leaked in a breached database, and whether your own mail domain is properly protected (SPF/DKIM/DMARC). No signup, no data retained.
We add new tools regularly. Check back sometime, or follow along.
We never ask for more data than we need, and we don't keep anything we don't need to keep.
No "free for 14 days" trick. Normal use stays free, period.
One tool, one job, done properly. No eleven-tab dashboard.
