Data controller and data processors

Information we collect

We collect information to provide and improve our service. The legal basis for processing depends on the specific context:

When you create an account with Reviy, we collect and store the personal information you explicitly provide during registration.

Registration via Google OAuth:

The data collected depends on what you authorize during the sign-in popup with your chosen provider. We only receive and store the information you explicitly consent to share through the OAuth provider's authorization flow.

Data security & retention

We implement technical and organizational security measures reasonably designed to protect your personal information from unauthorized access, disclosure, alteration, and destruction. This includes using secure services like Firebase for data storage and authentication, PostHog for analytics processing, and Mailchimp for marketing communications.

However, no method of transmission over the internet or electronic storage is 100% secure.

Data processed by PostHog on our behalf is stored within the European Economic Area (EEA).

We retain your personal data only for as long as necessary to fulfill the purposes for which it was collected, including for the duration of your account activity, and as required for legal, accounting, or reporting requirements.

  • Account data: retained until you delete your account or request erasure, subject to legal obligations.
  • Analytics data: collected via PostHog is typically retained for up to 12 months or until you withdraw consent.
  • Newsletter data: retained in Mailchimp until you unsubscribe or request deletion.

International data transfers

While we prioritize storing your data within the European Economic Area (EEA), some of our service providers process certain data in the United States:

  • Firebase Authentication (Google): Authentication services are processed in Google's US infrastructure, even when your primary Firebase region is set to europe-west.
  • PostHog analytics data: Stored within the EEA.
  • Mailchimp: May process data in the US, depending on configuration.
Data Transfer Safeguards: When your data is transferred outside the EEA, we ensure adequate protection through:
  • Standard Contractual Clauses (SCCs): Our processors (Google/Firebase, Mailchimp) use EU-approved Standard Contractual Clauses as mandated by GDPR.
  • Additional Security Measures: Our processors implement supplementary technical and organizational measures to protect data transferred to the US.

You can request more information about these safeguards by contacting us at matteo.beltrame@reviy.app.

Our service is intended for users who are at least 16 years of age. We do not knowingly collect personal information from individuals under 16 years old.

If you are under 16, please do not register for an account or provide any personal information to us. If we become aware that we have collected personal data from someone under 16 without parental consent, we will delete that information immediately upon request or discovery.

Parents/Guardians: If you believe your child under 16 has provided us with personal information, please contact us at matteo.beltrame@reviy.app and we will promptly delete such information.
