FlexTable is a native desktop app. Your databases are yours: it connects directly to them and does not proxy your data through its own servers.

​
Where your data is stored

Connections, settings, saved queries, history, and AI provider configs live in a single local SQLite database, flextable.db, in the app data directory:
OSLocation
macOS~/Library/Application Support/com.flextable.desktop/flextable.db
Windows%APPDATA%\com.flextable.desktop\flextable.db
Linux~/.local/share/com.flextable.desktop/flextable.db

​
Credentials and secrets

Connection passwords, SSH keys, and AI API keys are encrypted at rest with AES-256-GCM (Argon2id key derivation) and never leave your machine. The encryption is bound to your machine and user account, so the database file cannot be decrypted if it is copied elsewhere.
FlexTable does not use the OS keychain today, and the encryption is not based on a master password. It protects against casual inspection of the file and against copying it to another machine or account, but it is not keychain-grade on the same machine. OS-keychain integration is on the roadmap.
API keys are also write-only in the UI: after you save one, the app only ever shows a short fingerprint, never the key itself.

​
Telemetry

FlexTable collects no telemetry, analytics, or automatic crash reporting. There is nothing to opt out of. The only times FlexTable talks to the network, none of which is telemetry:
  • License activation with api.flextable.dev, required for licensing.
  • Update checks with api.flextable.dev (version and architecture only).
  • Feedback you explicitly submit from the feedback dialog (your message, plus optional app version/OS and email). Nothing is sent unless you fill it in and click submit.
  • AI requests go directly to the provider you configured, with your own key, never through FlexTable servers. See AI Assistant.
