Privacy policy
Draft pending legal review. This page will be finalised by counsel before launch.
This policy explains how Kelvin AI [legal entity — TBD] ("Kelvin", "we") collects and uses information through this website and through the Kelvin service we provide to HVAC businesses ("customers").
1. Two kinds of information
- Website visitors and prospects. When you request an audit or contact us, we are responsible for that information.
- Our customers' customers (homeowners). When an HVAC business uses Kelvin to contact its own customers, that business controls the data and we process it on its behalf under a data processing agreement. Homeowners with questions should contact the HVAC business first; we will help them respond.
2. What we collect on this website
- Details you submit: name, company, email, phone number, state, the software you use and approximate business size.
- Your consent choices for email and text messages, with the wording you agreed to, the time and your IP address.
- Campaign information in the link you followed (for example UTM parameters) and the referring page.
- Privacy-friendly, cookieless analytics (page views and form submissions, aggregated). We do not use advertising pixels or cross-site tracking cookies.
3. How we use it
- To respond to your audit request, schedule calls and deliver the audit.
- To send you emails and, only if you opted in, text messages about your request.
- To understand which pages and channels work, in aggregate.
- To meet legal obligations and keep records of consent.
4. Audit data
If you share an export from your field-service software for an audit, we use it only to produce your audit. If you do not become a customer, we delete it within 30 days.
5. Text messages
We send text messages only to numbers whose owners have agreed to receive them. Reply STOP to opt out at any time. We do not sell, rent or share mobile numbers or text-message opt-in data with third parties or affiliates for their marketing purposes. See our SMS terms.
6. AI and your data
We use AI models through zero-data-retention endpoints. Customer and homeowner data is never used to train AI models, ours or anyone else's. We do not create voiceprints or biometric identifiers.
7. Who we share it with
We use a small number of service providers (sub-processors) to host and operate Kelvin, listed on our sub-processors page. They may use the data only to provide their service to us. We do not sell personal information.
8. Where it's stored and how it's protected
Data is stored in the United States, encrypted in transit and at rest. Access is limited to people who need it, and access by our operations team is logged.
9. How long we keep it
- Audit requests from prospects who don't become customers: up to 24 months, then deleted. [Counsel to confirm.]
- Audit data: deleted within 30 days if you don't become a customer.
- Customer data: deleted within 30 days of contract end, after an export is offered.
- Opt-out and consent records: kept as long as the law requires to honour them.
10. Your choices and rights
You can ask us to access, correct or delete your information, or to stop contacting you, by emailing privacy@kelvin.example. Depending on your state you may have additional rights; we will honour them as required by law.
11. Children
Kelvin is a business service and is not directed at children under 16.
12. Changes and contact
We will post changes on this page and update the date above. Questions: privacy@kelvin.example · Kelvin AI [legal entity — TBD], [postal address — TBD].
