Questions, answered.
What should I check before using a reviews & loyalty tool under the GDPR?
Check which emails the tool sends and that each one offers an easy way to stop them. Decide how reviews are published: first name only, initials, or full name with agreement. Check how long points, reviews and referral data are kept. Record the region and any transfer outside the EEA.
Do I need a data processing agreement with a reviews & loyalty provider?
If the provider handles personal data on your behalf, yes: Article 28 of the GDPR requires a written contract. Some providers publish the text, others give it to you inside your account. Providers that decide their own purposes may act as independent controllers instead, so check the role.
