Privacy policy

Last updated: May 2026

1. Who we are

Phase Sight AI ("we", "us", "our") provides HVAC monitoring hardware and software for residential service contractors and multifamily property owners. This policy describes the information we collect, how we use it, and the rights you have over it.

2. Information we collect

Information you give us

When you sign up for our newsletter, request a portfolio assessment, request a demo, or pre-order a device, you provide information including your name, email address, company, role, portfolio size or fleet size, and any free-text message you choose to send us.

Information from your use of our hardware

Once an Irvin device is installed in an HVAC system, it transmits sensor readings (refrigerant pressure, line and air temperature, capacitor microfarad measurements, static airflow, condensate level) to our cloud platform. We associate these readings with the customer account responsible for that installation.

Information from your use of our website

We collect standard server logs (IP address, browser type, page visited, timestamp). We also use cookies for the purposes described in our cookie policy.

Payment information

When you pre-order or pay for a subscription, payment is processed by Stripe. We do not store full card numbers or other sensitive payment details on our own servers. We retain a transaction reference, the last four digits of the card, and the billing email.

3. How we use information

  • To provide the service you signed up for (deliver devices, run diagnostics, send alerts).
  • To respond to your inquiries and provide customer support.
  • To send service announcements (these are not promotional and cannot be opted out of while you have an active account).
  • To send marketing emails about new features and updates, if you've opted in. You can unsubscribe at any time.
  • To improve our products through aggregated and anonymized analysis of device telemetry.
  • To comply with legal obligations and enforce our terms of service.

4. How we share information

We share information only with the third parties we need to operate the service:

  • Stripe for payment processing.
  • Loops for email delivery.
  • Firebase / Google Cloud Platform for hosting, authentication, and database services.
  • Service contractors with whom you have an active relationship, when you've authorized them to view your device data.

We do not sell your personal information. We do not share it with advertising networks or data brokers.

5. Data retention

We retain account information for as long as your account is active and for a reasonable period afterward to support potential service inquiries and legal obligations. Device telemetry is retained for analytical and product-improvement purposes; aggregated anonymized data may be retained indefinitely.

6. Your rights

Depending on where you live, you may have the following rights regarding your personal data:

  • Access - request a copy of the personal data we hold about you.
  • Correction - ask us to fix inaccurate information.
  • Deletion - ask us to delete your data, subject to our legal obligations.
  • Portability - receive your data in a portable format.
  • Objection - object to specific uses of your data.
  • Withdrawal of consent - where we rely on consent, withdraw it at any time.

To exercise these rights, email hello@phasesight.ai. We respond within 30 days.

7. Children's privacy

Our service is not directed to children under 16. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it.

8. International data transfers

Phase Sight AI is based in the United States. If you access our service from outside the US, your information may be transferred to and processed in the US. By using the service, you consent to this transfer.

9. Security

We use industry-standard technical and organizational measures to protect personal information, including encryption in transit, access controls, and regular security reviews. No system is perfectly secure, however, and we cannot guarantee the security of information transmitted to us.

10. Changes to this policy

We may update this policy from time to time. When we make material changes, we will update the "Last updated" date and, where required by law, provide additional notice (such as an email to active customers).
