 ### End-to-end Encryption
 
 For end-to-end encryption, the encrypted data can be synced using PowerSync. The data can then either be encrypted and decrypted directly in memory by the application, or a separate local-only table can be used to persist the decrypted data — allowing querying the data directly.
 
+[Raw SQLite Tables](/usage/use-case-examples/raw-tables) can be used for full control over the SQLite schema and managing tables for the decrypted data. We have a [React & Supabase example app](https://github.com/powersync-community/react-supabase-chat-e2ee) that demonstrates this approach. See also the accompanying [blog post](https://www.powersync.com/blog/building-an-e2ee-chat-app-with-powersync-supabase).
