Last updated: April 2026

Agreement to Terms

By installing or using the Leif browser extension ("Service"), you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use the Service.

Description of Service

Leif is a browser extension that provides ESG (Environmental, Social, and Governance) sustainability scores and information for products and brands. The Service is provided for informational purposes only.

Use of the Service

You agree to use the Service only for lawful purposes and in accordance with these Terms. You agree not to:

Accounts

Some features require you to create an account. You are responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account.

Intellectual Property

The Service and its original content, features, and functionality are owned by Leif and are protected by copyright, trademark, and other intellectual property laws.

Affiliate Links and Product Information

The Service contains links to products on Amazon.com and other retail websites. These links may include affiliate tags, meaning Leif may earn a commission if you make a purchase through them. You are never charged more as a result of using these links.

Product information, prices, and availability shown in the extension are sourced from third-party data providers and Amazon, and may not reflect real-time values. The prices displayed reflect the most recent data available at the time indicated by the accompanying timestamp. Leif does not guarantee the accuracy of pricing or availability information and is not responsible for any discrepancies between the extension and the retailer's website. Users should always verify the final price and availability on Amazon before completing a purchase.

Disclaimer of Warranties

The Service is provided "as is" and "as available" without warranties of any kind, either express or implied. ESG scores and sustainability information are provided for informational purposes and should not be the sole basis for purchasing decisions.

Limitation of Liability

To the fullest extent permitted by law, Leif shall not be liable for any indirect, incidental, special, consequential, or punitive damages resulting from your use of the Service.

Changes to Terms

We reserve the right to modify these Terms at any time. We will provide notice of significant changes through the extension or via email. Your continued use of the Service after changes constitutes acceptance of the updated Terms.
