A restaurant loyalty program collects contact data (name, email, phone), behavioral data (visit frequency, time and day of visits, average spend, menu preferences), and engagement data (email open rates, offer redemption, WhatsApp response). This guest intelligence lets you segment your audience, identifying your top 20% of guests who drive 80% of revenue, targeting lapsed guests with win-back campaigns, and personalizing offers by preference or occasion. In the UAE, data collected through loyalty programs must comply with the UAE Personal Data Protection Law (PDPL), which requires transparent opt-in consent.
