1. About these Terms

These Terms and Conditions govern access to and use of the Open Hydro online platform under the annual subscription products for Pequenas Centrais Hidrelétricas (PCHs) and Centrais Geradoras Hidrelétricas (CGHs) in Brazil.

The services are provided by Open Hydro Ltd (“Open Hydro”, “we”, “us”) to business customers (“Customer”, “you”).

By accessing or using the subscribed service, the Customer agrees to these Terms.

Where a subscription is purchased through FastSpring, the purchase and payment transaction is also governed by FastSpring’s applicable terms of sale.

2. Subscription products and pricing

Open Hydro offers the following standard annual subscriptions:

Product	Annual subscription price
PCH Reservoir Emissions Monitoring	USD 500 per PCH
CGH Emissions Monitoring	USD 150 per CGH

Each subscription covers one identified hydropower plant for 12 months.

Prices are displayed in US dollars. Applicable taxes, currency conversion and payment charges, where relevant, are presented during checkout.

For purchases involving multiple plants, the Customer must identify the plants covered by the subscription. Any portfolio-specific pricing or additional services must be agreed separately in writing.

3. Services included

Subject to data availability and technical applicability, the subscription includes:

• Access to the Open Hydro online platform for the subscribed plant;
• Access to available greenhouse gas emissions estimates and related indicators for the plant;
• Available annual and periodic emissions information, including emissions intensity in gCO₂e/kWh where supported;
• Access to available visualisations and standard reporting or export functions;
• Reasonable support for account access and use of the platform.

For PCHs with qualifying reservoirs, the service may include monthly estimates of CO₂ and CH₄ reservoir emissions.

For CGHs, the available assessment depends on the plant’s physical characteristics, including whether a reservoir is present. A subscription does not guarantee reservoir-emissions estimates where the plant has no qualifying reservoir.

The exact indicators and features available for each plant will be confirmed during onboarding or in the applicable product description.

4. Services not included

Unless expressly agreed in writing, the subscription does not include:

• Independent verification or third-party assurance of emissions estimates;
• Issuance of carbon credits or carbon offsets;
• Automatic award of the Low-Carbon Hydro Label or other certification;
• Bespoke consulting studies or on-site measurements;
• Regulatory filing or submission of a GHG inventory on the Customer’s behalf;
• Water-quality monitoring features not yet included in the subscribed product.

Additional services may be offered under separate commercial terms.

5. Nature and limitations of emissions estimates

Open Hydro uses available datasets, remote sensing, analytical models and other relevant information to estimate environmental indicators.

These estimates are subject to methodological assumptions, data limitations, uncertainty and periodic updates.

The Customer acknowledges that:

• Modelled estimates are not necessarily equivalent to direct field measurements;
• Results may change as methodologies, models or input datasets are updated;
• Estimates should be interpreted within their stated scope and limitations;
• Regulatory applicability and reporting obligations must be assessed by the Customer;
• The service does not guarantee compliance with any specific reporting standard.

Open Hydro will use reasonable care and skill in providing the service.

6. Customer responsibilities

The Customer agrees to:

• Provide accurate information identifying the subscribed plants;
• Supply any reasonably requested operational or plant-specific data necessary for the agreed assessment;
• Ensure that it has the right to share such data with Open Hydro;
• Maintain the confidentiality of user credentials;
• Use the platform only for lawful business purposes;
• Avoid unauthorised access, redistribution or interference with the service.

The Customer remains responsible for decisions made using the platform’s outputs.

7. Subscription duration and renewal

Each subscription is valid for 12 months from the agreed activation date.

Subscriptions do not renew automatically.

At the end of the subscription period, the Customer may purchase a new annual subscription at the price and terms applicable at that time.

Open Hydro may contact the Customer before expiry to discuss renewal.

8. Payments and invoicing

Online payments are processed through FastSpring, acting as Merchant of Record.

FastSpring is responsible for the payment transaction and applicable transaction-related taxes in accordance with its terms.

Invoices or purchase receipts for transactions processed through FastSpring are issued through the applicable FastSpring process.

Access to the service may be conditional on successful payment and completion of onboarding requirements.

9. Cancellation and refunds

Customers may choose not to renew their subscription at the end of the 12-month period.

Requests to cancel an active subscription or obtain a refund are governed by the Open Hydro Refund Policy, FastSpring’s applicable terms and mandatory legal rights.

10. Intellectual property and permitted use

Open Hydro retains ownership of its platform, software, models, methodologies, documentation and associated intellectual property.

The Customer receives a limited, non-exclusive, non-transferable right to access and use the subscribed service for its internal business purposes during the subscription period.

The Customer may use and share its plant-specific reports and results for legitimate internal reporting, sustainability disclosures and communications with customers, subject to applicable confidentiality obligations and appropriate acknowledgement of the methodology and limitations.

The Customer may not resell platform access, reverse-engineer the software or commercially redistribute Open Hydro’s underlying models or datasets without written permission.

11. Customer data and confidentiality

The Customer retains ownership of data it provides to Open Hydro.

Open Hydro may process Customer data to deliver the subscribed service, maintain the platform, provide support and perform agreed analyses.

Open Hydro will treat non-public plant-specific information supplied by the Customer as confidential and will not disclose it to third parties except as necessary to deliver the service, with authorisation, or as required by law.

Any use of Customer-confidential data for external publications, identifiable case studies or marketing requires separate authorisation.

Personal data is handled in accordance with the Open Hydro Privacy Policy and applicable data-protection agreements.

12. Service availability and changes

Open Hydro will make reasonable efforts to maintain platform availability.

Temporary interruptions may occur because of maintenance, technical issues, third-party services or circumstances outside Open Hydro’s reasonable control.

Open Hydro may update the platform, models and methodologies to improve performance or maintain the service, provided that material changes do not substantially remove the core functionality purchased without an appropriate remedy.

13. Liability

Nothing in these Terms excludes or limits liability where doing so would be unlawful, including liability for fraud or fraudulent misrepresentation.

Subject to applicable law, Open Hydro is not responsible for indirect or consequential losses arising from use of the service.

Open Hydro’s aggregate contractual liability in connection with a subscription is limited to the amount paid for the affected subscription during the relevant 12-month period, except where such limitation is prohibited by law.

14. Suspension or termination

Open Hydro may suspend access where reasonably necessary to address security threats, unlawful use, material breaches of these Terms or non-payment.

Where practicable, Open Hydro will notify the Customer and provide an opportunity to resolve the issue.

Either party may terminate the agreement for a material breach that remains unresolved following reasonable written notice.

15. Governing law

These Terms are governed by the laws of England and Wales, subject to any mandatory laws that apply to the Customer and cannot lawfully be excluded.

The courts of England and Wales will have jurisdiction, except where mandatory applicable law provides otherwise.

Refund and Cancellation Policy

Effective date: 05.11.2026
Last updated: 09.11.2026

1. Overview

This Refund and Cancellation Policy applies to annual PCH and CGH subscriptions for the Open Hydro online platform.

We aim to provide clear subscription terms and fair treatment of our business customers.

Purchases processed through FastSpring are also subject to FastSpring’s applicable terms of sale and payment procedures.

2. Subscription prices

Subscription	Annual price
PCH Reservoir Emissions Monitoring	USD 500 per plant
CGH Emissions Monitoring	USD 150 per plant

Each subscription covers 12 months of access to the applicable service for one identified plant.

The final amount payable, including applicable taxes or currency conversion, is displayed during checkout.

3. Subscription duration and cancellation

Subscriptions are purchased for a fixed period of 12 months.

Subscriptions do not automatically renew.

Customers are not required to submit a cancellation request to prevent renewal.

Customers may notify Open Hydro at any time if they wish to discontinue use of the service.

Discontinuing use does not automatically entitle the Customer to a refund for the remaining subscription period.

4. Refund requests within 7 days

Customers may request a refund within 7 calendar days of purchase by contacting info@openhydro.net and providing their order reference.

As a goodwill policy, Open Hydro will generally approve a full refund within this period where:

• The request relates to the original subscription purchase;
• Substantive plant-specific emissions results or reports have not yet been delivered or made available;
• The subscription has not been substantially used.

Where the service has already been substantially delivered, refund eligibility will be assessed individually, taking into account the work performed and any applicable legal rights.

5. Refund requests after 7 days

After the initial 7-day period, subscription payments are generally non-refundable.

However, a refund or other appropriate remedy may be available where:

• Open Hydro is unable to provide the core subscribed service;
• The service materially differs from its agreed description;
• A duplicate or erroneous payment has occurred;
• A refund is required under applicable law or FastSpring’s terms.

Where only part of the service has been delivered, Open Hydro may offer a proportionate refund or an alternative remedy, depending on the circumstances.

6. Technical limitations and plant eligibility

Certain emissions estimates depend on plant characteristics, data availability and the technical applicability of Open Hydro’s methodologies.

If Open Hydro determines during onboarding that it cannot provide the core service purchased for the identified plant, the Customer will be offered an appropriate alternative or a full refund.

The Customer will not be required to accept a materially different service without agreement.

7. How to request a refund

To request a refund, please contact:

Email: info@openhydro.net

Please include:

• Company name;
• FastSpring order reference;
• Name of the subscribed PCH or CGH;
• Reason for the request.

Open Hydro aims to acknowledge refund requests within five business days.

Approved refunds will be processed through FastSpring, generally using the original payment method where supported.

The time required for funds to appear in the Customer’s account depends on the payment method, payment provider and banking arrangements.

8. Payment disputes and chargebacks

Customers are encouraged to contact Open Hydro first if they experience a problem with their subscription.

FastSpring may independently handle payment disputes, chargebacks, suspected fraudulent transactions and other payment-related matters in accordance with its applicable terms.

Nothing in this Policy limits any mandatory rights or remedies available under applicable law.

9. Changes to this Policy

Open Hydro may update this Refund and Cancellation Policy from time to time.

The policy applicable at the time of purchase will govern that transaction, subject to applicable law and any mandatory rights.

3. Environmental and operational data

Open Hydro may also process hydropower plant information, reservoir characteristics, electricity generation data, water-quality measurements and other environmental or operational datasets.

These datasets are generally business or technical information rather than personal data.

Where such information is confidential, its use is governed by our contractual confidentiality commitments and any applicable data-sharing agreement.

If any dataset contains personal information, the relevant data-protection obligations will also apply.

4. How we use personal information

We use personal information to:

We do not sell personal data to advertisers.

5. Legal bases for processing

Where UK GDPR applies, we rely on the appropriate legal basis depending on the activity, including:

• Contractual necessity: where processing is necessary for a contract with the individual;
• Legitimate interests: for customer relationship management, platform security and service improvement, where those interests are not overridden by individuals’ rights;
• Legal obligations: where information must be retained or processed to comply with law;

Customer contact information and correspondence may be maintained in our customer relationship management systems, including HubSpot, for the duration of the business relationship and for an appropriate period thereafter where necessary for legitimate business purposes.

Subscription and transaction information received from FastSpring may be retained for account administration, customer support, accounting, contractual and legal purposes. FastSpring separately manages information that it processes and retains in accordance with its own privacy policies and legal obligations.

Platform account information and technical records are retained for as long as necessary for account management, security, troubleshooting and service operation, taking into account the purposes of processing and applicable legal requirements.

We review the personal information we hold and delete or anonymise it when it is no longer required, unless continued retention is necessary or permitted under applicable law.

Individuals may contact info@openhydro.net to request information about the retention of their personal data or to exercise applicable data protection rights.

10. Data security

We use appropriate technical and organisational measures designed to protect personal information against unauthorised access, loss, alteration and disclosure.

These measures may include access controls, authentication, encryption where appropriate, backups, security monitoring and restrictions on personnel access.
