Note: This page covers data integrity (how safety data is recorded, attributed, and preserved under the ALCOA+ framework). For privacy and personal-data handling across Holistic Quality services, see the HQ Data Policy (Version 2.0, April 2026).
The Holistic Quality safety database applies rigorous, auditable data-integrity practices to consumer safety information. Every claim is traceable. Every update is logged.
We organize our data-integrity practices around the ALCOA+ principles — a widely-used data-integrity model. Applied to our safety database:
Of 4,133 entries, 3,801 record which process created them and last reviewed them, and when; no entry yet names a human reviewer.
Data is structured consistently so humans and applications can read it reliably.
Entries are dated when created. Timestamps reflect when work was actually done.
We cite primary sources (EPA, MSDS, peer-reviewed research) rather than secondary summaries when possible.
Information reflects what sources actually say. We don't editorialize or spin data.
The + extends these principles:
We don't cherry-pick. If sources conflict (e.g., IARC vs EPA on carcinogenicity), we present both.
Every chemical entry follows the same structure. Same fields, same format, same rigor.
Data persists. Revision history is maintained. Nothing is silently deleted.
Information is accessible when you need it. No paywalls. No extraction.
We categorize sources by authority:

If we cannot cite a claim, we mark the entry as draft until
proper sourcing is established.
Every entry maintains a revision history showing:
Each entry carries its own change log. Over the last 60 days it recorded 75% of content changes (80% for compounds, 80% for materials, 8% for products).
Each entry has a status indicating its review state:
draft — Initial entry, may have incomplete sourcesactive — Reviewed and verifiedunder_review — Being updated or disputeddeprecated — Outdated, superseded, or found to be incorrectIf you find inaccurate information, missing sources, or outdated data, please report it:
Corrections are reviewed by the Holistic Quality team and logged in revision history with attribution to the reporter (or anonymous if preferred).
Our safety data structure is open. The schema is published. Truth shouldn't be paywalled.
Applications in the HQ ecosystem — including the ALETHEIA API — pull from this shared database, presenting the same underlying truth in context-appropriate ways.
