How it works

Clearya is activated when you visit supported shopping websites (currently: Amazon, Target, Sephora, iHerb and Walmart). When you browse a webpage in a supported product category (beauty products, personal care, baby care and cleaning products), Clearya "wakes up" and automatically searches the webpage for the product's ingredient list. Clearya then checks if any of the listed ingredients is identified as a substance of concern according to several authoritative chemical hazard lists (see which ones below). Many ingredients have tens of different trade names and synonyms, so Clearya checks if the listed ingredients may be identified as toxicants under different names. In addition to flagging products based on their ingredient lists, Clearya may flag other types of products based on reports from product testing labs which inspect products for undisclosed contaminants. Click the Clearya button at the top of the product page to review the results.

In addition to using the Clearya mobile app and Chrome/Edge extension while shopping online, you may use the "Capture Ingredients" feature on the Clearya mobile app when shopping in-store, as well as for checking products at home. Simply use your device's camera to snap a photo of the product label. Alternatively, select a product image from your photo gallery. Clearya will extract the ingredient list text from the photo and analyze it for you. For best results, ensure the image is clear and focused, and crop it to include only the ingredient list.

Note that Clearya does not analyze labels of food products, dietary supplements or drugs.

Clearya alerts
Clearya's alerts provide information about chemicals included in the product's ingredient list that are recognized by authoritative chemical hazard lists as chemicals of concern. Review the alert details to decide what alerts are relevant to your situation. When you click an alert you can see the following details:

You can personalize the type of alerts you'd like Clearya to display to you by modifying the default Alert Settings. For example, you can choose not to be shown alerts on allergens, or on ingredients that are only potentially toxic.

When Clearya displays an "Ingredients Not Listed" status it means that a proper Ingredients section wasn't found in the product page. In this case, Clearya cannot assess whether the product includes ingredients of concern or not. Likewise, Clearya may flag generic terms, such as "fragrance" which do not disclose the actual substances being used.

Product discovery
When you browse a product Clearya may display a list of related products for which Clearya did not identify unsafe ingredients, carried by the same shop. The collection of related products will be growing over time: when Clearya users browse new products Clearya automatically assesses their ingredient safety and adds relevant products to the alternatives collection, for the benefit of the rest of the users. Clearya is not paid by brands or retailers for including their products.

Our goal is to provide accurate and relevant information to help you decide which products are right for you. However, it's important to know that our analysis is limited by several factors:

Please help us improve: let us know if you think something isn't right.

Hazard vs. Risk
Note that the potential health risk posed by a chemical hazard depends on the actual exposure (which is a function of concentration, frequency of exposures, route of exposure and more), and on individual factors. Clearya does not assess potential health risks posed by products. It informs consumers of hazardous ingredients, so that they may apply the precautionary principle and reduce their exposure to toxic chemicals.

Supported shopping websites
Clearya currently supports Amazon, Target, Sephora, iHerb, and Walmart. We're busy adding additional online shopping websites, so stay tuned.

We update our chemical and toxicology sources periodically.
