Two things the EU information duties ask a shop to produce, kept where the shop finds them again. The Omnibus prior price: the lowest price in effect in the 30 days before a reduction, computed from your own recorded price history. And a shop-level record of which notices were active, and when they changed. No shopper data is stored: no customer id, no e-mail, not even a hash. Whether your shop meets a duty is for a qualified professional to judge; this app gives the record and the arithmetic.

• Withdrawal, GPSR and AI-notice blocks for your theme, in your own words.
• Omnibus prior price, computed from your own recorded price history.
• A shop-level, anonymous evidence log: which notices changed, and when.
• The three mandatory GDPR webhooks, HMAC-verified, with erasure that erases.
• Built by one person plus automation; no shopper data is stored.
