Privacy and local data

Local data is classified before release.

NATIVE038 inventories browser-profile, cache, Mission, evidence, diagnostic, download, policy, and support data. The goal is to define what exists, where it belongs, how it is retained, and what must never enter evidence or support output.

Local-data classes

Different data requires different handling.

Final behavior remains subject to native runtime and packaging proof. This page describes current source-level privacy rules, not a released binary’s final retention controls.

Browser profile

Normal Chromium profile data such as history, cookies, cache, site permissions, and session state stays within the relevant profile boundary.

Mission data

Mission structure, recipes, pane roles, timeline metadata, notes, and user-created operational context require profile-scoped handling.

Evidence data

Evidence output must be deliberate, reviewable, and redaction-aware. It must not silently absorb browser secrets.

Diagnostics

Support output is planned to be metadata-only and to include redaction reporting rather than private browsing payloads.

Downloads

Downloaded files remain user-controlled files and must not be silently included in support or evidence bundles.

Policy data

Active policy truth may be reported without exposing credentials or unrelated private content.

Absolute exclusions

Secrets do not belong in evidence or support output.

The source rules explicitly prevent the following categories from entering evidence or support bundles.

CookiesSession tokensPasswordsCredentialsAuthorization headersRefresh tokensAPI secretsRaw browser storageCopied authentication data

TAHAI services

The browser is not the authority.

Safe references and authorized links may connect users to TAHAI Portal, IT Docs, PSA, or other services. The browser does not become an authentication authority, credential vault, or provider-connector host.

Authorization boundary: IT Docs and PSA operations remain server-authorized. Local IDs and Mission references never grant access by themselves.

Status

Final privacy controls require runtime proof.

Retention choices, deletion behavior, profile migration, support-bundle generation, and installed-package behavior will be finalized and documented through the remaining passes.
