Vantic hashes them at the point of capture using SHA-256. The original string is discarded immediately and cannot be recovered. Hashes are used only for detecting repetition and continuity — not for reading what the title said. ## Why "architecture" not "policy" Content inside applications is not on the ingestion path. That is a different posture from "we collect everything and apply access controls." The privacy boundary is structural — enforced at capture, not downstream. See [Privacy-safe by architecture](/concepts/your-privacy-guarantee) for the full explanation. ## Auto-exclusions The following categories are excluded by default and cannot be re-enabled: * Password managers (1Password, Bitwarden, LastPass, macOS Keychain) * Australian banking applications * macOS system credential prompts and dialogs The live list includes **Australian banking applications** and **password managers** as described on the [Security](/resources/security) page. These exclusions are applied before any signals from those contexts are processed. *** How the structural privacy boundary works. Add your own exclusions and manage your data.
