2.4. You shall not share, sell, transfer, sublicense, or otherwise make your API Keys available to any third party without our prior written consent.

2.5. We reserve the right to revoke any API Key at any time, with or without cause, and with or without notice.

4. Subscription Plans and Overages

4.1. The Service is offered under various Subscription Plans, including a free tier with limited usage. Details of each plan, including pricing, Usage Limits, and features, are set out on the pricing page of the Service.

4.2. Paid Subscription Plans are billed in advance on either a monthly or annual recurring basis, depending on the billing cycle you select at checkout. All payments are processed via Stripe. By subscribing to a paid plan, you authorize us to charge your designated payment method at the then-current rate for your selected plan on each renewal date.

4.3. All fees are quoted in United States Dollars (USD) unless otherwise stated and are exclusive of VAT and any other applicable taxes, which shall be charged in addition where required by law.

4.4. You are responsible for providing accurate and up-to-date billing information, including your business name, address, and VAT number where applicable, to ensure invoices are correctly issued.

4.5. We reserve the right to change our pricing at any time. Any price changes shall take effect at the start of your next billing cycle following notice of such change. Continued use of the Service after a price change constitutes acceptance of the new pricing.

4.6. Usage Limits. Usage Limits. Each Subscription Plan includes a monthly API request allowance. Paid plans include a grace buffer above your plan's monthly allowance, the size of which varies by plan (up to 50%) and is detailed on the pricing page. The free tier does not include a grace buffer. Once you exceed your allowance (or grace buffer, if applicable), further API requests will be rejected with a 429 (Too Many Requests) response until the start of your next billing cycle. We recommend monitoring your usage via the dashboard and upgrading your plan before reaching your limit.

4.7. Rate Limits. Each Subscription Plan includes per-second rate limits and burst allowances designed to ensure fair usage and service stability. Requests exceeding these limits will receive a 429 (Too Many Requests) response. Current rate limits for each plan are published on the pricing page.

5. Payment Processing and Security

5.1. Payment Processor. We use Stripe, Inc. and its affiliates (“Stripe”) as our third-party payment processor. By subscribing to a paid plan, you agree to be bound by Stripe’s Services Agreement, available at https://stripe.com/gb/legal/ssa.

5.2. PCI-DSS Compliance. The Service is designed to be compliant with the Payment Card Industry Data Security Standard (PCI-DSS). We do not store, process, or transmit your full credit card numbers or sensitive authentication data on our servers. All payment information is securely transmitted directly to Stripe via encryption.

5.3. Automatic Renewals. Paid Subscription Plans are billed on a subscription basis. You expressly authorise us (via Stripe) to charge your designated payment method for the applicable subscription fees on a recurring monthly basis until you cancel your subscription.

5.4. Failed Payments. If a payment fails (e.g., due to expiration, insufficient funds, or bank declination), we may suspend your access to the Service until payment is successfully processed. You remain responsible for any uncollected amounts.

6. Carbon Offset Purchases

6.1. Service Description. The Service offers the ability to purchase carbon offsets to neutralise CO₂e emissions calculated through the API. Carbon credits are sourced from verified registry projects and permanently retired on your behalf by CarbonCert™, a third-party verification and retirement service operated by Brighter Planet Inc. By purchasing an offset, you acknowledge and agree to be bound by the CarbonCert™ Terms of Service.

6.2. Intermediary Role. The Company acts as an intermediary and technology provider between you and CarbonCert™. We do not operate carbon registries, nor do we directly retire carbon credits. All retirements are performed by CarbonCert™ through projects certified by Verra (VCS), Gold Standard, or the UNFCCC Clean Development Mechanism. We act solely as an agent for the facilitation of this transaction and make no representations or warranties regarding the continued solvency, operational uptime, or future performance of CarbonCert™ or the underlying carbon registries.

6.3. Pricing. Carbon offsets are priced per tonne of CO₂e at the rate displayed on the offsets dashboard at the time of purchase. Prices are quoted in United States Dollars (USD) and are exclusive of any applicable taxes, including Value Added Tax (VAT), which will be added at checkout where required by law. We reserve the right to change offset pricing at any time; any price change shall apply to purchases made after the change takes effect.

6.4. Payment. Offset purchases are charged immediately to your payment method on file via Stripe. A minimum purchase amount applies, as displayed on the offsets dashboard. All offset payments are one-off charges separate from your subscription fees.

6.5. Auto-Offset. You may enable automatic monthly offset purchases. When enabled, we will calculate your total emissions for the preceding calendar month and charge your payment method on file for the corresponding offset amount. If the price per tonne increases, we will notify you prior to your next billing cycle, providing you the opportunity to disable the feature before the new rate applies. You may disable auto-offset at any time through the dashboard. Disabling auto-offset shall take effect from the next billing cycle; no refund shall be issued for auto-offsets already processed.

6.6. Non-Refundable and Right to Cancel. Offset purchases are non-refundable once carbon credits have been retired on the source registry. By purchasing an offset, you expressly consent to the immediate commencement of the retirement process and acknowledge that you lose your statutory right to cancel the service (the 14-day cooling-off period) once the credits are retired. You acknowledge that retired carbon credits are consumed immediately and cannot be returned. If you dispute a charge, you agree to contact us first to attempt resolution. If a chargeback is processed for credits that have already been retired, you shall remain fully liable to us for the original purchase amount plus any administrative or dispute fees incurred from our payment processor. In the event that CarbonCert™ is unable to complete a retirement, we will either arrange an alternative retirement of equivalent value or issue a full refund at our discretion.

6.7. Verification. Each offset purchase receives a unique CarbonCert™ verification ID linking to the retirement record on the source registry. You acknowledge and agree that the provision of this verification ID (or the successful return of a 'confirmed' status via the API) constitutes full and final delivery of the Service. Verification IDs are displayed in your offset history and included in compliance PDF exports. Verification timelines depend on CarbonCert™ processing and registry procedures; we do not guarantee a specific timeframe for verification.

6.8. No Project Allocation Guarantee. While all credits are sourced from projects certified by recognised registries, we do not guarantee allocation to any specific project, geography, or credit vintage unless expressly agreed in writing.

6.9. No Compliance Guarantee. Carbon offset purchases are intended to support your voluntary emissions reduction efforts. The Company does not warrant that offset purchases satisfy any specific regulatory, compliance, or reporting obligation. You are solely responsible for determining whether carbon offsets meet the requirements of any applicable regulatory framework, including but not limited to CSRD, SECR, or CDP.

6.10. Third-Party Dependency. The availability and fulfilment of carbon offsets depends on CarbonCert™ and the underlying carbon registries. The Company shall not be liable for any failure, delay, or inability to retire credits caused by CarbonCert™, registry downtime, credit supply shortages, or other factors beyond our reasonable control.

6.11. Data Sharing. To facilitate carbon credit retirement, we share limited information with CarbonCert™ including your name/business name, country, and a platform reference identifier. This data is used solely for the purpose of retirement processing and certificate generation. CarbonCert™'s handling of this data is subject to the CarbonCert™ Privacy Policy.

7. Refund Policy

7.1. All fees paid are non-refundable. This includes, without limitation, monthly subscription fees, overage charges, and any other charges incurred through use of the Service.

7.2. Downgrading your Subscription Plan shall take effect at the end of the current billing period. No pro-rata refund shall be issued for the remainder of any billing period in which a downgrade is requested.

7.3. Upgrading your Subscription Plan shall take effect immediately, and you shall be charged a pro-rated amount for the remainder of the current billing period.

7.4. In exceptional circumstances, refunds may be considered at the sole discretion of the Company. Any such refund shall not constitute a waiver of such refund policy in the future.

7.5. Nothing in this clause shall affect your statutory rights under the Consumer Rights Act 2015 or any other applicable consumer protection legislation where you are contracting as a consumer.

8. Service Availability and SLA

8.1. Service Level Agreement (SLA). For the Scale Plan, we commit to a Monthly Uptime Percentage of 99.9%. No other plans carry a specific uptime commitment.

8.2. Free, Launch, Starter & Growth Plans. The Service is provided on an "as available" basis without a specific uptime guarantee. We will use commercially reasonable efforts to maintain availability but do not provide financial remedies for downtime on these tiers.

8.3. Remedy. If we fail to meet the specific Monthly Uptime Percentage for your paid plan, your sole and exclusive remedy for such failure shall be the receipt of a Service Credit calculated as a percentage of your monthly subscription fee. To receive a Service Credit, you must submit a claim to [email protected] within thirty (30) days of the incident.

8.4. Exclusions. The SLA does not apply to any unavailability, suspension, or termination of the Service caused by: (a) factors outside of our reasonable control (force majeure); (b) your use of the Service in violation of these Terms; or (c) scheduled maintenance windows.

8.5. Support. Support is provided in accordance with your Subscription Plan. Free-tier customers receive community support (documentation and guides). Launch and Starter plans receive email support. Growth and Scale plans receive priority email support.

9. Data and Accuracy

9.1. The Service provides carbon emission calculations based on publicly available emission factor databases, including but not limited to DEFRA, EPA eGRID, Ember, and the GLEC Framework. We endeavour to use the most current and accurate data sources available.

9.2. The data and calculations provided by the Service are for informational and estimation purposes only. They do not constitute professional environmental advice, certified carbon accounting, or regulatory compliance validation.

9.3. Whilst we use commercially reasonable efforts to ensure the accuracy of our calculations, we make no warranty or representation that the emission factors, grid intensity data, or calculation results are complete, accurate, or fit for any particular purpose.

9.4. You are solely responsible for verifying the accuracy and suitability of any data obtained through the Service before relying upon it for any purpose, including but not limited to regulatory reporting, carbon offsetting, or commercial decision-making.

9.5. Emission factors and methodology may be updated from time to time, which may result in different calculation outputs for the same input parameters. We shall endeavour to document material changes in our changelog.

10. Intellectual Property

10.1. The Service, including all software, APIs, documentation, designs, algorithms, data compilations, trade marks, and other materials, is the property of the Company or its licensors and is protected by applicable Intellectual Property Rights.

10.2. These Terms do not grant you any right, title, or interest in the Service except for the limited licence expressly set out in clause 3.1.

10.3. You retain all rights in any data you submit to the Service. By submitting data to the Service, you grant us a limited, non-exclusive licence to process such data solely for the purpose of providing the Service to you.

(b) we reasonably believe your use of the Service poses a security risk to the Service or any third party;

(d) you fail to pay any amounts due under these Terms;

(e) you significantly exceed your Usage Limits and fail to pay associated overage fees or upgrade your Subscription Plan upon request; or

(f) we are required to do so by law or regulation.

11.2. Cancellation. You may cancel your subscription at any time through the account dashboard or by contacting us at [email protected]. For monthly plans, cancellation shall take effect at the end of the current monthly billing period. For annual plans, cancellation shall take effect at the end of the current annual billing period; no pro-rata refund shall be issued for the remaining months of an annual term. Upon cancellation, your account will revert to the free tier at the end of your paid billing period, and you will retain access to your paid plan features until that date.

11.3. Account Deletion. You may permanently delete your account at any time through the account dashboard. Deleting your account will revoke all API keys and permanently remove your account data. This action cannot be undone. We will attempt to cancel any active subscriptions automatically upon account deletion; however, it is your responsibility to confirm that your subscription has been cancelled via your Stripe billing portal or by contacting us at [email protected]. Deletion of your account does not entitle you to a refund for any remaining portion of a paid billing period. We may retain certain data (such as billing records) as required by law in accordance with our Privacy Policy.
