1. About These Terms

These Terms and Conditions ("Terms") govern your use of the Dashe mobile application and associated services (together, the "Service"), operated by Greenleaf TDG, a company registered in the United Kingdom ("we", "us", "our").

By creating an account or using the Service, you confirm that you have read, understood, and agree to be bound by these Terms, together with our Privacy Policy and Cookie Policy. If you do not agree with any part of these Terms, you must not use the Service.

We may update these Terms from time to time. We will notify you of material changes through the app or by email. Your continued use of the Service after changes are posted constitutes your acceptance of the updated Terms.

2. Eligibility

To use the Service, you must:

  • Be at least 16 years of age.
  • Have the legal capacity to enter into a binding agreement.
  • Provide accurate and complete information when creating your account.

If you are using the Service on behalf of an organisation, you confirm that you have the authority to bind that organisation to these Terms.

3. The Service

Dashe is a carbon emission tracking application that:

  • Automatically detects and records your journeys using GPS and activity recognition.
  • Classifies your mode of transport (driving, walking, cycling, and other modes).
  • Calculates and displays your carbon emissions based on your journeys and registered vehicles.
  • Allows you to join an organisation for corporate carbon reporting.
  • Provides car sharing features to split emissions among journey participants.
  • Enables you to log work schedules and holidays for commute analysis.

We reserve the right to modify, suspend, or discontinue any part of the Service at any time, with or without notice. We will use reasonable efforts to notify you of significant changes that affect your use of the Service.

4. Pricing and Subscriptions

4.1 Individual Users

The Dashe mobile app is free to download and use for individual users. There is no charge for journey tracking, emission calculation, or any personal features of the Service.

4.2 Business Subscriptions

Organisations that wish to access the Dashe web application, reporting dashboards, and organisational data features must purchase a paid subscription ("Business Subscription"). Business Subscriptions are priced based on headcount and site count and are subject to a separate subscription agreement between Greenleaf TDG and the subscribing organisation.

4.3 Subscription Terms

The following terms apply to Business Subscriptions:

  • Billing: Subscription fees are invoiced in accordance with the subscription agreement. All fees are quoted exclusive of VAT, which will be added where applicable.
  • Payment: Fees must be paid by the due date specified on the invoice. We reserve the right to suspend access to the web application and organisational features if payment is not received within 30 days of the due date.
  • Changes to pricing: We may change our subscription pricing with at least 30 days' written notice before the start of your next billing period. If you do not agree to the new pricing, you may cancel your subscription before the new pricing takes effect.
  • Cancellation: Either party may cancel a Business Subscription in accordance with the terms of the subscription agreement. Upon cancellation, the organisation's access to the web application and reporting features will end at the conclusion of the current billing period.
  • Refunds: Subscription fees are non-refundable except where required by law or as otherwise agreed in writing.
  • Individual users are not affected: Cancellation of a Business Subscription does not affect the accounts or data of individual users who were part of the organisation. Those users may continue to use the free mobile app.

5. Your Account

5.1 Account Creation

You must create an account to use the Service. You agree to provide accurate, current, and complete information during registration and to keep your account information up to date.

5.2 Account Security

You are responsible for maintaining the confidentiality of your account credentials. You agree to notify us immediately at support@dashe.ai if you become aware of any unauthorised use of your account. We are not liable for any loss or damage arising from your failure to protect your account credentials.

5.3 One Account Per Person

Each person may only maintain one account. We reserve the right to suspend or terminate duplicate accounts.

6. Permissions and Device Access

To provide the Service, the Dashe app requires access to certain features on your device:

Permission Why It Is Needed Required
Location (Always / Background) Automatic journey detection and tracking, even when the app is not in the foreground Yes (core functionality)
Activity Recognition Detecting your mode of transport (walking, driving, cycling, etc.) Yes (core functionality)
Motion and Pedometer Supporting transport mode classification and step counting Yes (core functionality)
Notifications Alerting you about journey updates, organisation invitations, and service messages Optional

You may revoke these permissions at any time through your device settings. However, revoking required permissions will prevent core features of the Service from functioning.

7. Acceptable Use

You agree to use the Service lawfully and in accordance with these Terms. You must not:

  • Use the Service for any unlawful purpose or in violation of any applicable law or regulation.
  • Attempt to gain unauthorised access to the Service, other users' accounts, or our systems and networks.
  • Interfere with or disrupt the integrity or performance of the Service.
  • Reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code of the app, except where permitted by law.
  • Use automated scripts, bots, or other tools to access or interact with the Service without our prior written consent.
  • Submit false, misleading, or inaccurate information to the Service, including falsified journey data or vehicle details.
  • Impersonate any person or entity, or misrepresent your affiliation with any person or entity.
  • Use the Service to collect, harvest, or store personal data of other users without their consent.
  • Share your car share session codes publicly or use them to manipulate emission data.

We reserve the right to suspend or terminate your account if we reasonably believe you have breached these Terms.

8. Organisations

If you join an organisation within Dashe (for example, your employer):

  • Certain journey and emission data may be shared with your organisation's administrators for the purpose of corporate carbon reporting, as described in our Privacy Policy.
  • Your organisation may set policies or schedules that affect how your journeys are categorised (e.g. commute vs. personal travel).
  • You may leave an organisation at any time through the app. Data already shared with the organisation in aggregated form may not be retrievable.
  • Organisation administrators are responsible for their own use of data shared through the Service and must comply with applicable data protection laws.

9. Car Sharing

The car sharing feature allows multiple Dashe users to link their journeys and split carbon emissions among occupants. When using this feature:

  • You are responsible for sharing your car share session code only with the intended participants.
  • Emission calculations are based on the number of participants who join the session and the vehicle details provided.
  • We are not responsible for inaccurate emission splits caused by incorrect participant counts or users failing to join or leave a session.

10. Vehicle Data and DVLA Lookups

The Service allows you to register vehicles using your vehicle registration number. When you do so:

  • We look up publicly available vehicle information (make, model, fuel type, CO2 emission rate) from DVLA data.
  • You confirm that you are the registered keeper of the vehicle or have the keeper's permission to register it.
  • Vehicle data is used solely for carbon emission calculations. We do not share your registration number with third parties except as necessary to perform the lookup.
  • We do not guarantee the accuracy of data provided by external sources such as the DVLA. If the data appears incorrect, please contact us.

11. Accuracy of Data and Emissions

Please read this section carefully.

Dashe uses GPS, activity recognition, and vehicle data to estimate your carbon emissions. While we strive for accuracy, you acknowledge and agree that:

  • Emission calculations are estimates and should not be treated as precise scientific measurements.
  • GPS accuracy can be affected by environmental factors (buildings, tunnels, weather), device hardware, and battery-saving settings.
  • Automatic transport mode detection may occasionally misclassify your mode of travel. You can correct this manually within the app.
  • Emission factors are based on published averages and may not reflect the exact emissions of your specific vehicle under specific driving conditions.
  • We update our emission factors and calculation methods periodically, which may result in changes to historical data.

You should not rely solely on Dashe data for regulatory reporting, legal compliance, or any purpose requiring certified emission measurements.

12. Intellectual Property

If any provision of these Terms is found to be unfair under the Consumer Rights Act 2015, it will not bind you, but the remainder of these Terms will continue to apply.

19. Governing Law and Disputes

These Terms are governed by and construed in accordance with the laws of England and Wales.

If you are a consumer, you may bring legal proceedings in the courts of the part of the United Kingdom in which you live. If you are a business, any disputes shall be subject to the exclusive jurisdiction of the courts of England and Wales.

We encourage you to contact us first at support@dashe.ai to resolve any dispute informally before taking legal action.
