Gemini is a capable general assistant with broad multimodal reasoning and close integration with Google services. Choose it when those services define the main use case.
Data architecture
For Google Gemini, the relevant feature path is: google-account data handling follows gemini apps activity and current privacy controls; google cloud processing; retention and human-review conditions depend on settings and service needs. Read the provider's current policy for retention, sharing, and account controls.
For Catina, imported health records are stored in an encrypted local Health Vault. Standard protection uses backend-assisted unlock and includes Catina's account service in the access path. Extra Local Protection separately adds passphrase-gated local encryption.
On current sensitive AI paths, the browser verifies an attested enclave before establishing a secure session. A verification failure stops the sensitive request. Request and response bodies are encrypted end to end to that enclave. Headers and operational metadata needed for authentication, routing, rate limits, and billing can remain visible to the relay. A verified secure session may be reused for up to 30 minutes, with attestation occurring when the session is established or refreshed.
Recommendation by use case
