A privacy and evidence boundary for owner authorization, minimum scopes, revocation, deletion, and read-only vehicle data.
Ask only for the evidence the job needs
A responsible authorization flow names the provider, requested read scope, retention window, vehicle binding, and deletion path before the owner grants access. Location, media, contacts, cabin data, and state-changing commands should remain outside a diagnostic recorder that does not need them.
Authorization is not ownership
Tokens should be encrypted, rotated where the provider permits, bound to one account and vehicle record, and removed when the owner disconnects. The product should retain a privacy-reduced evidence record rather than treating long-lived access as the default.
- Use the provider's approved OAuth flow.
- Keep client secrets on the server.
- Provide one-step connection deletion.
- Record unavailable signals as unavailable.
Make the report independently understandable
A useful report names the source, capture period, sampled signals, missing channels, processing version, and integrity fingerprint. It should not imply a manufacturer endorsement or a confirmed diagnosis.
THE TAKEAWAYOwner authorization, minimum collection, clear revocation, and bounded evidence make connected diagnostics useful without turning the vehicle into a surveillance product.
ScanWrench Editorial created this issue from the platform's evidence model and reviewed educational workflows. It separates observed facts, plausible paths, decisive tests, safety limits, and remaining unknowns. Its purpose is to improve vehicle decisions; it does not replace exact manufacturer procedures or qualified professional judgment.
