Our Privacy & Data Principles
Every application we create adheres to strict transparency, minimal data retention, and user sovereignty standards.
On-Device Local Storage
No mandatory cloud accounts, usernames, or remote profile synchronization. Your data stays in your device's sandboxed local storage.
Ephemeral AI Processing
When AI speech synthesis is requested, text is streamed transiently in memory over HTTPS (TLS 1.3) and never saved or indexed on our TTS servers.
Strict Child Safety
Full compliance with COPPA and GDPR-K regulations. Roleplay and simulation tools feature adult gate verification for parental operation.
Instant Data Erasure
Deleting an item within the app or uninstalling the application permanently wipes all profiles, audio caches, and settings with no residual traces.
