Trust & attribution

ServiceLedger is built on tools and datasets we can name in plain English — critical for courtroom-grade calm on the service drive.

NHTSA recall data

Open recall summaries are queried from NHTSA public datasets and APIs. We display structured facts with source links so customers can verify directly with the federal register of safety campaigns.

LubeLogger (MIT)

Maintenance intelligence routes through a fork of LubeLogger, which ships under the MIT License. Commercial use is permitted with attribution; we maintain separation between open tooling and proprietary report composition per CarStack architecture notes.

Human review

PDFs are not legal advice. Shops remain responsible for diagnosis, repair quality, and customer disclosures. ServiceLedger accelerates transparency; it does not replace technician judgment.
