GDPR Loyalty Programme Small Business Guide

Loyalty programmes collect customer data. What GDPR requires of small businesses, what you can and cannot do, and how to stay compliant.

GDPR does not stop you from running a loyalty programme. It stops you from running one badly. Here is what every small business owner needs to know — without the legal jargon.

GDPR has a reputation for complexity that frightens small business owners away from data-driven tools. The reality for a loyalty programme is more straightforward: collect only what you need, tell customers what you are collecting and why, keep it secure, and give customers control over their own data. Here is how that works in practice.

What Data Do Loyalty Programmes Typically Collect?

  • Name (first name is usually sufficient)
  • Mobile phone number or email address (for card delivery and communications)
  • Visit history and transaction dates (not always itemised)
  • Points balance and redemption history
  • Optionally: date of birth (for birthday offers)

The Legal Basis for Collecting Loyalty Data

Under GDPR, you need a legal basis for processing personal data. For a loyalty programme, two bases typically apply: legitimate interests (you have a genuine business reason to track purchases for a rewards programme your customer has chosen to join), and consent (for marketing communications sent beyond the functional programme communications). Be clear which applies to which data type.

What You MUST Tell Customers at Sign-Up

  • What data you collect
  • Why you are collecting it (to run the loyalty programme)
  • How long you will keep it
  • Whether you share it with third parties (and if so, who)
  • How they can access or delete their data

Data Retention: How Long Can You Keep Loyalty Data?

There is no fixed GDPR retention period — it must be proportionate to the purpose. For a loyalty programme, keeping data for as long as a member is active plus 12 months after their last interaction is a defensible retention policy. After that, data should be anonymised or deleted.

Customer Rights Under GDPR

  • Right to access: a customer can ask for a copy of all data you hold about them
  • Right to deletion ('right to be forgotten'): they can request deletion of their account and data
  • Right to portability: they can request their data in a machine-readable format
  • Right to rectification: they can correct inaccurate data

What to Do If a Customer Asks to Be Forgotten

You must delete their personal data within 30 days of the request. Keep a record that the request was made and fulfilled (without retaining the personal data itself). Your loyalty platform should have a 'delete member' function that handles this automatically.

A simple GDPR-compliant sign-up script: 'We will save your name and contact details to run your loyalty account, send you reward notifications, and occasional offers. You can unsubscribe or delete your account at any time by asking us or contacting [email].' That covers the essentials.

Frequently Asked Questions

Do I need a Data Protection Officer (DPO)?

Almost certainly not. A DPO is only required for organisations that process large volumes of sensitive personal data or conduct large-scale systematic monitoring. A small business loyalty programme does not trigger this requirement.

What if I use a third-party loyalty platform like Loyenix?

You are the data controller (you decide what data is collected and why). The platform provider is the data processor (they process data on your behalf). You should have a data processing agreement in place — Loyenix provides this as part of its terms of service. The platform's compliance with GDPR reduces but does not eliminate your own obligations.

73% of consumers say they trust businesses with loyalty programmes more when they explain clearly how their data is used — consumer trust survey
