5. Data Storage and Security

Your data is stored in a Supabase database hosted on Amazon Web Services (AWS) infrastructure. We take the security of your data seriously and employ the following measures:

• Encryption in transit: All data transmitted between your device and our servers is encrypted using TLS (Transport Layer Security).
• Row Level Security (RLS): Our database enforces Row Level Security policies, meaning you can only access your own data and data from matches in which you participate. Other users cannot query or view your personal information.
• Local storage: Some data is stored locally on your device using SwiftData for offline access. This data remains on your device and is protected by your device's built-in security features.

We retain your personal information for as long as your account is active. If you request deletion of your account, we will delete your personal data from our servers. Some information may be retained in aggregated or anonymized form that cannot be used to identify you.

Match data (scores, statistics, settlements) associated with other players may be retained in those players' match histories, but your personal identifiers will be removed upon account deletion.
