Last updated: March 2026

1. Introduction

Simmer (“we”, “us”, “our”) is committed to protecting your privacy. This policy explains what personal data we collect, how we use it, and your rights under applicable data protection laws including the UK GDPR and EU GDPR.

  • Recipe content: recipes you create, import, or photograph, including ingredients, steps, notes, adaptations, and photos.
  • Organisation data: collections, meal plans, shopping lists, cooking history, and person tags.
  • Family data: family membership details when you use the family sharing feature.
  • AI interactions: messages you send to the AI Chef Chat feature.
  • Usage data: basic analytics such as feature usage and error logs to improve the service.

3. How We Use Your Data

7. Cookies

Simmer uses only essential cookies required for authentication and session management. We do not use tracking cookies, advertising cookies, or third-party analytics cookies. No cookie consent is required for essential cookies under GDPR, but we inform you of their use for transparency.

8. Data Retention
