Schools and care homes using Allergy Spotter can save every edit to a pupil's or resident's allergy register as a tamper-evident record. If a school or care home has switched on public verification, you can check here — no login, no account — whether their register's edit history is intact.
Tip: paste the school or care home's Allergy Spotter link, or just its slug from the link.
Each time a pupil's or resident's allergy record is added to or changed on the register, the entry saved includes a fingerprint of the entry right before it — like a chain of wax seals. This tool re-checks every seal in a school or care home's chain from the very first entry to the most recent. If even one old entry had been quietly edited afterwards, every seal after it would break, and this check would catch it and tell you exactly where.
Worth being honest about: this proves the chain hasn't been altered since it was created without also being caught. It doesn't yet prove independence from Allergy Spotter itself — the chain and the entries it protects both still live in our own database, so this is closer to "we've shown our working and it holds up" than "checked against something entirely outside our control." Anchoring the chain somewhere fully external to us is a possible future step, not something this page claims today.
This check never reveals any pupil's or resident's name, allergies, or record — only whether the chain is unbroken and how many edits it covers.
