Overview
- An internet‑representative survey for the vzbv found 78% use at least one supermarket app and 61% of users say their shopping behavior has changed.
- Two thirds of users reported buying more in the past two years to unlock app‑exclusive deals or benefits.
- Supermarket apps require personal registration and track detailed purchase and location data, while roughly 29% of non‑users avoid them over privacy concerns.
- The vzbv calls for prohibiting manipulative interface tactics such as gamified tiers, timed coupons and collection mechanics, and for restricting ad profiling.
- A legal case against Lidl challenges marketing of Lidl‑Plus as “free,” as price‑tracker Smhaggle estimates average real savings from app coupons at about 2%.
