Privacy Policy

Last updated: May 4, 2026

Your Privacy Matters

AutoHVAC, Inc. ("AutoHVAC," "we," "us," or "our") provides AI-powered HVAC load calculation software to professional contractors. This Privacy Policy explains what personal information we collect when you visit autohvac.ai or use our services, how we use and share that information, and the choices and rights you have. It applies to all users of the AutoHVAC platform.

Loading your privacy preferences…

1. Information We Collect

Account & Profile Information

When you create an account or contact us, we collect:

  • Email address, name, and (optionally) company information
  • Password (stored as a salted, one-way hash — we never see plain text)
  • Phone number (if you provide one)
  • Communications you send to support, sales, or feedback channels

Project & Usage Data

To provide our services we collect and process:

  • Blueprint files and architectural drawings you upload
  • Building specifications, ZIP codes, and project parameters you enter
  • Generated load calculation reports and analysis output
  • Usage events such as uploads, report generations, and feature interactions

Payment Information

Subscription billing is processed by Stripe. Payment card data is sent directly from your browser to Stripe and is never stored on AutoHVAC servers. We receive only a transaction reference, the last four digits of your card, the billing postal code, and subscription status.

Device & Technical Information

We automatically collect, through cookies and similar technologies:

  • IP address, browser type, device type, operating system, and language
  • Referring URL, pages viewed, links clicked, and time spent
  • Approximate location derived from IP address (city/region level)
  • Diagnostic and error logs for security and reliability

Identifiers Used for Advertising Measurement

When you submit your email or phone number through our forms, we transmit a cryptographically hashed (SHA-256) version of those values to our advertising and measurement partners (Google and Meta) so they can match your conversion event to a prior ad click. Hashing reduces re-identification risk but does not anonymize the data: under US privacy law, hashed identifiers remain personal information that can be linked back to you by the recipient platform.

2. How We Use Your Information

Service Delivery

  • Authenticate your account and provide the AutoHVAC platform
  • Process blueprints into HVAC load calculations and reports
  • Send transactional emails (receipts, account alerts, report completions)
  • Provide customer support and respond to inquiries

Platform Improvement & Security

  • Monitor for abuse, fraud, and security incidents
  • Debug, troubleshoot, and improve product performance
  • Develop new features based on aggregated usage patterns
  • Train and refine our internal AI extraction logic (we do not train external AI models on your data — see Section 4)

Marketing & Advertising

  • Measure the performance of our marketing campaigns and attribute conversions
  • Build audiences of existing customers to exclude from prospecting ads
  • Show relevant ads to prospective customers on Google and Meta platforms
  • Send promotional emails (you may opt out at any time via the unsubscribe link)

Legal & Compliance

  • Comply with applicable laws, regulations, and lawful requests
  • Enforce our Terms of Service
  • Establish, exercise, or defend legal claims

3. Advertising, Analytics & Tracking Technologies

We use cookies, pixels, software development kits (SDKs), and server-to-server APIs from the providers listed below. Some of these tools transmit hashed identifiers and event data to third parties for cross-context behavioral advertising, which qualifies as a "sale" or "share" of personal information under California law and the laws of several other US states. See Section 8 ("Your Privacy Rights") for instructions on how to opt out.

Google Analytics 4 & Google Ads

We use Google Analytics 4 ("GA4") with the following Google Advertising Features enabled: Google Signals, Enhanced Conversions for Web, User-Provided Data Collection, Remarketing, and Demographics & Interest Reporting. Our GA4 property is linked to a Google Ads account, and conversion events (such as completed purchases and lead submissions) are imported into Google Ads to measure ad performance and inform automated bidding.

When you complete a purchase or submit a free-report request, we transmit a hashed SHA-256 version of your email address (and phone number, if provided) to Google. Google uses this hash to match your conversion to a prior signed-in Google session, improving cross-device attribution. Google may also associate analytics data with its own information about your signed-in Google account if you have Ads Personalization enabled in your Google account settings.

You can opt out of Google's use of your data for advertising through any of the following:

Meta (Facebook) Pixel & Conversions API

We use the Meta Pixel and the Meta Conversions API ("CAPI") to measure the effectiveness of advertising on Facebook and Instagram, build custom audiences, and attribute conversions. The Pixel runs in your browser; CAPI runs on our servers and transmits the same events directly from our backend to Meta with an event ID for deduplication.

When you submit your email through our forms (lead capture, checkout, or purchase), we transmit a SHA-256 hashed version of your email address — and your phone number if provided — to Meta. We also transmit non-identifying event metadata such as the event name (e.g., Lead, Purchase), value, currency, and timestamp.

You can manage Meta's use of your data at https://www.facebook.com/adpreferences/ad_settings and at Instagram's ad preferences. You can also opt out of interest-based advertising via the Digital Advertising Alliance at https://optout.aboutads.info/.

Microsoft Clarity (Session Replay)

Important — Session Recording Notice: We use Microsoft Clarity to record visitor interactions on our website. Clarity captures mouse movements, clicks, scrolls, page views, and pages visited in order to generate aggregated heatmaps and session replays we use to improve our user experience. Form input fields are masked by default and we do not collect keystrokes within form inputs. Recordings are transmitted to and stored by Microsoft Corporation, an independent third party that processes the data on its own servers consistent with Microsoft's Privacy Statement. By continuing to use this site, you consent to this recording.

PostHog (Product Analytics)

We use PostHog to capture product usage events (such as feature clicks, uploads, and conversions) for the purpose of improving our software. PostHog is configured to identify users by email after sign-in so that we can analyze longitudinal product behavior. PostHog is hosted on our behalf and acts as a service provider — it does not use your data for its own purposes. See PostHog's privacy policy.

Subprocessor Summary

The following service providers receive personal data on our behalf:

  • Google LLC — analytics, advertising measurement, email infrastructure
  • Meta Platforms, Inc. — advertising measurement, audience building
  • Microsoft Corporation — session replay (Microsoft Clarity)
  • PostHog Inc. — product analytics
  • OpenAI, L.L.C. — AI vision processing of uploaded blueprints (see Section 4)
  • Stripe, Inc. — payment processing
  • Amazon Web Services — cloud infrastructure and storage
  • Render Services, Inc. — application hosting

Do Not Track ("DNT") and Global Privacy Control ("GPC")

Most modern browsers offer a "Do Not Track" setting and a "Global Privacy Control" signal that can communicate your privacy preferences to websites. We treat a valid GPC signal as an opt-out request from selling and sharing your personal information for cross-context behavioral advertising and as an opt-out of targeted advertising under applicable state privacy laws. When we detect a GPC signal we will, where technically feasible, disable advertising-purpose data sharing for the duration of your visit. We do not currently respond to legacy DNT browser signals because there is no industry-standard interpretation of those signals.

4. AI Processing of Your Uploads

AutoHVAC's load-calculation pipeline includes a vision step that uses OpenAI's API (GPT-4 class models) to extract architectural information from blueprints you upload. Specifically, our backend converts pages of your PDF to images and sends those images to OpenAI's API along with a structured prompt requesting items like room labels, perimeter measurements, and door/window counts.

Per OpenAI's API Data Usage Policy:

  • Content submitted through OpenAI's API is not used to train OpenAI's models.
  • OpenAI may retain submitted content for up to 30 days for abuse and misuse monitoring, after which it is deleted.
  • We do not include personal identifiers (such as your name or email) in the prompt beyond what may already appear visibly on the blueprint itself.

See OpenAI's privacy policy and API data usage terms.

5. How We Share Personal Information

We do not sell your personal information for money. We do, however, share certain personal information as described in this Section 5 and Section 3 above. Some of that sharing constitutes a "sale" or "share" under California's CCPA/CPRA and equivalent definitions in other US state privacy laws — see Section 8 for your right to opt out.

Service Providers

We share personal information with the subprocessors listed in Section 3 strictly to perform services on our behalf, under written contracts that prohibit them from using the data for their own purposes.

Advertising & Analytics Partners

We share hashed identifiers and event data with Google and Meta so that they can attribute ad clicks to conversions, build audiences, and personalize advertising. Although these partners are technically processors for some of these activities, certain uses (such as cross-context behavioral advertising) qualify as a "sale" or "share" of personal information under US state privacy laws.

Business Transfers

If we are involved in a merger, acquisition, financing, reorganization, or sale of assets, personal information may be transferred to the successor entity, subject to the commitments in this Privacy Policy.

Legal & Safety

We may disclose personal information when we have a good-faith belief that disclosure is necessary to (a) comply with applicable law or valid legal process, (b) enforce our Terms of Service, (c) protect the rights, property, or safety of AutoHVAC, our users, or the public, or (d) investigate suspected fraud or wrongdoing.

6. Data Security

Enterprise-Grade Security

We protect your data with industry-standard administrative, technical, and physical safeguards. No method of transmission over the internet or storage is 100% secure, however, and we cannot guarantee absolute security.

  • Encryption in transit: All connections use TLS 1.2 or higher
  • Encryption at rest: Database and file storage encrypted with AES-256
  • Access controls: Role-based access, multi-factor authentication for staff, audit logging
  • Infrastructure: AWS and Render data centers with SOC 2 controls
  • Backups: Encrypted, geographically distributed, and routinely tested
  • Vulnerability management: Dependency monitoring, security review of code changes, periodic penetration testing
  • Incident response: Documented breach-notification procedures consistent with applicable state laws

7. Data Retention

We retain personal information only as long as needed for the purposes described in this Policy:

  • Account data: While your account is active, plus up to 90 days after closure for billing and support
  • Project data and reports: While your account is active; deleted within 90 days of account closure
  • Blueprint files: Retained for the life of the project; you may request earlier deletion at any time
  • Analytics and advertising data: Retained according to GA4's default 14-month window and Meta's default windows; aggregated reports may be retained longer

  • Directly from you (account creation, uploads, support)
  • Automatically from your device and browser (cookies, server logs)
  • From service providers and partners (advertising attribution, payment processors)

Purposes for Collection

See Section 2 ("How We Use Your Information") for the full list.

Categories of Recipients

See Section 3 ("Subprocessor Summary") and Section 5 ("How We Share Personal Information").

Right to Opt Out of Sale / Sharing

California residents have the right to opt out of the "sale" or "sharing" of personal information. To exercise this right, email support@autohvac.ai with "Do Not Sell or Share" in the subject line, or enable a Global Privacy Control browser signal as described in Section 8. When you opt out, we will visibly indicate that the opt-out preference signal has been honored.

Shine the Light

California's "Shine the Light" law (Cal. Civ. Code § 1798.83) permits California residents to request information about disclosures of personal information to third parties for those parties' direct marketing purposes. We do not disclose personal information to third parties for their own direct marketing.

10. Notice for Other US State Residents

Residents of states with comprehensive privacy laws — including Virginia, Colorado, Connecticut, Utah, Texas, Oregon, Montana, Iowa, Delaware, New Jersey, New Hampshire, Tennessee, Nebraska, Minnesota, Indiana, Kentucky, Rhode Island, Maryland, and Florida — have the rights described in Section 8. Where state law requires, we honor a Universal Opt-Out Mechanism (such as Global Privacy Control) and provide an appeals process for denied requests.

11. International Users

AutoHVAC operates from the United States and our subprocessors are primarily located in the United States. If you access our services from outside the US, your information will be transferred to and processed in the United States, where data protection laws may differ from your jurisdiction. Our services are not directed at residents of the European Economic Area, the United Kingdom, or other regions with comprehensive non-US privacy laws, and we do not solicit business from such residents.

12. Children's Privacy

AutoHVAC is a professional B2B tool not intended for individuals under the age of 18. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us at support@autohvac.ai and we will delete it.
