Terms of Service

Last updated: July 20, 2026

Greenlens is free to use, shows you other people's published opinions about cosmetics, and is not a doctor. The long version is below. By using the Greenlens web app, browser extension, or mobile app you agree to these terms.

What Greenlens is

Greenlens aggregates publicly available cosmetics ratings from independent sources, shows where those sources disagree, and computes a composite score using weights you control — on the web, in a browser extension, and in a mobile app that scans product barcodes. The ratings belong to their sources; Greenlens reports them, including their disagreements, and never invents or hides one.

Not medical or professional advice

Everything Greenlens shows is informational. Scores, verdicts, ingredient flags, and Sonion's commentary are summaries of third-party opinions, not medical, dermatological, or safety advice. If you have allergies, sensitivities, a skin condition, or are pregnant or nursing, talk to a qualified professional before acting on anything you read here. Do not stop or start using a product solely because of a Greenlens score.

No warranty on ratings data

Ratings come from external sources (for example Open Beauty Facts) and are matched to products by software. We work to keep matches accurate and we show each match's confidence, but we cannot guarantee that any rating, ingredient list, or product match is complete, current, or correct. The service is provided “as is”, without warranties of any kind.

Affiliate links

As an Amazon Associate, Greenlens earns from qualifying purchases. Some product pages link to Amazon with an affiliate tag; if you buy through one, Greenlens may receive a commission at no extra cost to you. Affiliate income never changes a score, a ranking, or which alternatives we suggest. Alternatives are ranked by safety, never by payout.

Billing and subscriptions

Where Greenlens Pro is offered, it is offered as a free beta: starting it puts a card on file through Stripe, nothing is charged during the trial, and we will email you before any charge ever starts. You can cancel anytime from the billing portal on your account page. Because the beta is free, refunds do not apply. Stripe processes all payments; we never see or store your card number. Pro is only ever purchased and managed on the web at usegreenlens.com; the mobile apps never sell subscriptions or take payments.

Acceptable use

The web app and its API endpoints exist to serve people looking up products. Don't abuse them: no scraping at volume, no automated traffic designed to overload the service, no attempts to bypass rate limits, and no use of the data to misrepresent what a rating source said. We may block traffic that ignores this.

The browser extension

The extension reads publicly visible product information on retailer pages you visit and shows ratings for it. It runs only on sites you have allowed. Retailer sites belong to their operators; the extension does not modify your purchases or interfere with checkout.

The mobile app

The mobile app uses your phone's camera solely to read product barcodes; scanning a barcode looks the product up in our catalog and may add a product's public record from Open Beauty Facts to it (see the Privacy Policy for exactly what is and isn't collected). The app is distributed through the Apple App Store and Google Play, and your use of it is also subject to those stores' own terms.

Limitation of liability

To the fullest extent permitted by law, Greenlens and its operator are not liable for any damages arising from your use of the service, including decisions made based on ratings shown, product purchases, or service interruptions.

Changes

We may update these terms as the product evolves. The date above reflects the latest revision; continued use after a change means you accept it.
