3. Information Sharing

We retain your data while your account is active. If you delete your account, we permanently delete your personal data and recipes within 30 days, unless required by law to retain them.

We use encryption in transit (TLS) and at rest, and Supabase’s Row Level Security (RLS) to ensure your private recipes are only accessible to you.
If you become aware of a security issue, contact us at security@rationau.com.
