Editorial policy

What we promise

• Primary sources first. Laws from the legislature, certifications from the certifier, specs from the manufacturer. See the methodology.
• Every claim shows its status. Each fact carries a label and a source link right next to it.
• No fake reviews. Untested products get a profile, never a review or a "best" ranking.
• No fake freshness. An "updated" date only moves when a fact changed. Every change is logged on What changed.
• No hype. No countdowns, no fake scarcity, no inflated savings claims.
• Money never sets a label. An affiliate program or a sponsorship never changes whether a product is listed as compliant. See the affiliate disclosure.
