Nothing is sent to our servers about an individual shopper. The
storefront offer bar reads the merchant's current discount config (code, value,
time window) from a public, non-personal endpoint — the same response is served to
every visitor.
To avoid re-showing a deal a shopper has already used or dismissed, the app writes
small flags directly to that shopper's own browser
(localStorage) — for example, "seen today" or "redeemed" markers keyed
to a product ID. These flags never leave the shopper's device and are never
transmitted to Flash Discounts or to the merchant.
A companion Shopify web pixel listens for the storefront's own
checkout_completed event so it can mark a purchased product as
redeemed in that same browser storage. It does not send order details, payment
information, or any personal data anywhere — it only writes a local flag in the
shopper's browser.
