GDPR for Restaurants: What Customer Data Can You Keep in 2026?
GDPR governs how restaurants collect and store customer data — names, emails, order history. Here is what you may keep, your lawful basis, retention limits, and the right to erasure.
GDPR for restaurants is the EU data-protection rule set that governs how a restaurant may collect, store, use, and delete personal data about its customers — names, emails, phone numbers, addresses, and order history. This is not legal advice.
If you serve or market to people in the EU/EEA, GDPR applies even if your restaurant is elsewhere.
What customer data can a restaurant keep?
You may keep data you actually need for a clear purpose: contact details to fulfill and deliver an order, an address for delivery, order history to run loyalty, and email for marketing if the customer opted in. You should not keep data "just in case".
What is your lawful basis?
Every use of personal data needs a lawful basis. The common ones for restaurants are:
- Contract — you need the address and phone to deliver the order.
- Consent — marketing emails and SMS require a clear opt-in.
- Legitimate interest — fraud prevention or basic analytics, balanced against privacy.
How long can you retain it?
GDPR has no fixed number — the rule is "no longer than necessary." Practical patterns: keep order/transaction records as long as tax law requires (often 6–10 years for financial data), but scrub marketing contact data when a customer goes inactive (for example 24–36 months) or asks you to stop.
What is the right to erasure?
A customer can ask you to delete their personal data ("right to be forgotten"). You must remove identifying data — but you keep the monetary/financial record for tax, just anonymized. Direct Dine builds this in: erasure scrubs name, email, phone, and notes while retaining order totals, plus a DSAR export so a customer can download their data. This is not legal advice.
When is this NOT a worry?
- Truly anonymous, no-account walk-in cash sales with no personal data captured.
- If you collect nothing beyond an anonymized order, there is little personal data to govern.
But the moment you store an email, phone, or delivery address, GDPR is in scope — so choose a platform that handles consent, retention, and erasure for you.
