Terms of Service

Last Updated: February 18, 2026

1. Acceptance of Terms

By accessing and using CarbonGuru, you accept and agree to be bound by these Terms of Service and our Privacy Policy.

2. Description of Service

CarbonGuru provides carbon footprint analysis services through:

  • Browser extension — analyzes shopping carts and product pages to estimate the carbon footprint of your purchases
  • Email analysis — connects to your Gmail account (with your permission) to extract purchase information from order confirmation and receipt emails
  • Carbon offsets and removals — allows you to purchase verified carbon offsets and removals to compensate for the footprint of your purchases
  • Website dashboard — displays your carbon footprint history, order details, and offset portfolio

3. User Responsibilities

You are responsible for:

  • Maintaining the confidentiality of your account
  • All activities that occur under your account
  • Ensuring you have authority to grant access to any email account you connect

4. Acceptable Use

You agree not to:

  • Use the service for any illegal purpose
  • Attempt to gain unauthorized access to our systems
  • Interfere with the proper functioning of the service
  • Submit content designed to exploit or disrupt our analysis systems

5. Gmail API Usage

By connecting your Gmail account, you authorize CarbonGuru to access your email messages using Google’s Gmail API with read-only access. CarbonGuru cannot modify, delete, or send emails on your behalf.

CarbonGuru accesses only order confirmations, receipts, and invoices for the purpose of carbon footprint analysis. Email content is processed in memory and is not stored after product data has been extracted.

To extract product information from emails, preprocessed email content is sent to AI service providers acting as sub-processors on CarbonGuru’s behalf. These providers process content solely for product identification and do not retain or independently use the data.

CarbonGuru’s use of Gmail data complies with the Google API Services User Data Policy, including the Limited Use requirements. See our Privacy Policy for full details.

You may revoke Gmail access at any time through your CarbonGuru account settings or through Google Account Permissions.

6. Carbon Offset and Removal Purchases

Carbon offsets and removals purchased through CarbonGuru are fulfilled by our provider, CNaught. Payments are processed by Stripe and PayPal.

Carbon credits are retired on your behalf through verified registries (Verra, Puro.earth, and others). Once credits have been retired, purchases are non-refundable, as retirement is an irreversible action on the public registry.

CarbonGuru does not guarantee the accuracy of carbon footprint estimates. Estimates are based on publicly available lifecycle assessment data and may differ from the actual environmental impact of specific products.

7. Data and Privacy

Your use of CarbonGuru is also governed by our Privacy Policy, which describes what data we collect, how we use it, and your rights. By using the service, you consent to the practices described in the Privacy Policy.

8. Limitation of Liability

CarbonGuru is provided “as is” without warranties of any kind, express or implied. We are not liable for any indirect, incidental, or consequential damages arising from your use of the service, including but not limited to the accuracy of carbon footprint estimates or the environmental impact of purchased offsets.

9. Termination

You may terminate your account at any time through your account settings or by contacting us. We reserve the right to terminate or suspend access to our service for violations of these terms.

Upon termination, your Gmail connection (if any) will be disconnected and tokens revoked. Your carbon footprint history will be retained unless you request deletion.

10. Changes to Terms

We reserve the right to modify these terms at any time. Material changes will be communicated through the service or by email. Continued use of the service after changes constitutes acceptance of modified terms.

11. Governing Law

These Terms are governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to conflict of law provisions.
