What counts as a scan?
A single completed scan of one URL. Failed fetches, blocked hosts and invalid URLs do not consume scan credits.
Can I scan anything?
Any public website. Private IPs, localhost, internal-only TLDs and unsafe schemes are rejected before any network call.
Do you store scanned sites?
We store the resulting report, not a full copy of the target site. Reports contain extracted evidence only.
Is this legal advice?
No. Signal is a heuristic scanner. Findings describe likelihoods based on public signals and are strictly informational.
Which currency?
EUR. Lemon Squeezy acts as merchant of record, which simplifies VAT and invoicing across the EU and Balkans.
Can I cancel anytime?
Yes. Subscriptions can be cancelled at any time. Access continues until the end of the current billing period.
Signal diagnoses. Cadmus rebuilds. We work with a short list of boutique European clients each quarter.
