Overview

• A decision is expected on 23 September 2025 at the Oberlandesgericht Stuttgart in the Verbraucherzentrale Bundesverband's cease‑and‑desist case against Lidl.
• The consumer group argues Lidl Plus does not make explicit that access to app‑exclusive discounts requires sharing personal data.
• Lidl confirms the app records details such as the visited store and redeemed coupons, stating the data support store network planning and personalized advertising.
• Price analysis by Smhaggle found modest average savings from loyalty programs in Q1 2025, including 2.29% with Kaufland Card, 0.82% with Rewe Bonus, and 0.75% with the Penny app.
• Surveys indicate loyalty apps can increase shopping frequency and spending, while many users criticize data collection, and Aldi Nord and Aldi Süd currently do not offer such programs.
