321ZERO is a carbon measurement and reporting platform built in Jersey, Channel Islands. We handle personal data in accordance with the Data Protection (Jersey) Law 2018. JOIC registration is in progress. You can contact us at privacy@321zero.je about this policy or a data rights request.
We do not currently operate a separate product analytics or behavioural tracking system. We do not collect data directly from utility providers.
The platform's primary store for dashboard and emissions data is your browser's localStorage. This means the data is normally kept on the device and within the browser profile you use. It is not automatically protected by Supabase Row Level Security and may be accessible to other people who can use your unlocked device or browser profile. Clearing site data, using private browsing, changing device or reinstalling the browser may remove locally stored data.
Supabase is used for authentication and may store account metadata, published ticker information, or other server-side records required by enabled features. Netlify hosts and delivers the website and may process request and deployment logs.
Supabase infrastructure used by this service may be located in the London AWS region (eu-west-2). London is in the United Kingdom and is not in the European Union. Provider processing may also involve other locations described in their own service and subprocessors documentation.
We do not sell your personal data. We do share or make data available to service providers where necessary to run the platform:
These providers act as processors or subprocessors for relevant data. They may use their own subprocessors as described in their terms and privacy documentation.
We do not send your emissions data to the Government of Jersey, JFSC or another reporting body on your behalf unless a feature clearly asks for your authorisation. Reports generated for download or email remain your responsibility to review and submit.
Information you opt to publish in a ticker is intentionally made public and may be viewed, copied or indexed by others.
Depending on the context, we process data to provide the service you request, to pursue legitimate interests such as security and support, to comply with legal obligations, or on the basis of consent for optional publication.
Where providers process data outside Jersey, including in the United Kingdom, we rely on the provider arrangements and applicable legal safeguards available for that processing.
Subject to applicable conditions and exemptions under Jersey law, you may have rights to:
Local dashboard data can be reviewed or removed through the platform and your browser's site-data controls. To exercise a right concerning server-side data, email privacy@321zero.je. We may need to verify your identity before acting on a request.
Browser data remains in localStorage until you delete it, clear the browser's site data, or the browser removes it. Account and other server-side records are retained while needed to provide the service and for reasonable security, support or legal purposes.
A dashboard deletion action first removes data available on the device and may also attempt to remove related server records. Server deletion is not guaranteed to be immediate: it can be delayed or fail because of a network, authentication or provider error. If the interface reports a failure, or if you want confirmation that server-side data has been removed, contact us at privacy@321zero.je. Limited records may be retained where required by law or necessary to resolve security and legal matters.
Connections to the deployed service use HTTPS. Supabase Auth handles account authentication and password storage; 321ZERO does not receive or store your plain-text password. No internet or browser storage system is completely secure, so you should use a strong, unique password, protect access to your device and keep your own exports or backups where appropriate.
We may update this policy as the service and its providers change. The date at the top identifies the latest version. Material changes will be presented through the platform or another reasonable channel where practicable.
Questions or requests can be sent to privacy@321zero.je.
