Restaurants using Allergy Spotter can save every guest's "yes, I checked my allergies" confirmation as a tamper-evident record. If a restaurant has switched on public verification, you can check here — no login, no account — whether their record is intact.
Tip: paste the restaurant's Allergy Spotter menu link, or just its slug from the link.
Each time a guest confirms they've checked their allergies and intolerances, the record saved includes a fingerprint of the record right before it — like a chain of wax seals. This tool re-checks every seal in a restaurant's chain, in order, and counts the confirmations that are not in the chain at all — it can only vouch for the confirmations that are in the chain. If even one old record 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 records 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 guest's name, allergies, or order — only whether the chain is unbroken, how many confirmations it covers, and how many it does not. Where a card was checked while the restaurant had no internet connection, it also shows the name of the till that checked it and the two times involved: when the check was made, and when it reached the record.
