HVAC POCKET PRO — PRIVACY POLICY

Product: Ductless Master and related HVAC Pocket Pro services (the “Service”)
Effective date: September 14, 2026
Last updated: October 3, 2026
Provider: HVAC Pocket Pro LLC, an Illinois limited liability company (“HVAC Pocket Pro,” “we,” “us,” or “our”)

REQUEST TO DELETE YOUR DUCTLESS MASTER ACCOUNT

You can delete your account in the Ductless Master app by opening Settings → Delete Account. If you cannot access the app, email info@hvacpocketpro.com with “Ductless Master account deletion request” in the subject line. When possible, contact us from the email associated with your account. Do not send a password or other secret. We may ask for information reasonably needed to verify that the account is yours.

We will review and respond to deletion requests as required by applicable law. Some information may be retained for the reasons and periods described in Section 6.1. Deleting your Ductless Master account does not cancel an Apple App Store or Google Play subscription or stop store billing. Cancel a subscription separately through the store account used to purchase it.

1. INTRODUCTION

This Privacy Policy explains how HVAC Pocket Pro LLC collects, uses, shares, retains, and protects information when you use Ductless Master, our website, and related services. It applies to information collected online and through the mobile application. Third-party services that publish their own privacy notices are not governed by this Policy.

The Service is intended for people age 18 and older. This Policy describes our current practices. Where applicable law requires consent for a particular use of information, we will request that consent as required.

2. INFORMATION WE COLLECT

2.1 Information you provide

Depending on how you use the Service, we may collect:

• Account and authentication information, including a Firebase Authentication user identifier (UID), authentication-provider information, and, when you provide it, your name and email address. Anonymous or limited sign-in may create a randomly generated UID without requiring a name, email, or password.

• Feedback and support information, such as your name, email address, message, equipment model, app screen, suggested correction, attachments, and our replies.

• Promotional request and redemption information, such as your name, company or employer, email address, request details, promo code, redemption time, eligibility information, and grant status.

• Subscription and entitlement information, such as subscription status, plan or entitlement, purchase source, promotional access, expiration, and identifiers needed to reconcile access. Apple and Google process store purchases. We do not store your payment-card number.

• Content you submit or request, such as search terms, documents or images you upload or request, saved configurations, field notes, diagnostic information. Do not submit unnecessary customer personal information, credentials, trade secrets, or confidential information.

• Legal acceptance information. When an authenticated user accepts the EULA, our server records the verified Firebase UID, available name and email fetched from Firebase Authentication, a server-generated timestamp, the EULA version and effective date, app version, and platform. The current record uses EULA version 2026-09-14 and effective date 2026-09-14.

2.2 Information collected automatically

We and our providers may collect:

• Device platform, operating-system and application version, device or installation identifiers, language, and basic technical information.

• Dates and times of sign-ins, sessions, requests, feature use, document or content views, errors, and subscription checks.

• Network and security information, such as IP address, approximate region derived from an IP address, browser or app information, and abuse or rate-limit events.

• Operational logs, diagnostics, crash information, and performance information.

We use cookies, local storage, cached content, or similar technologies as needed to operate the website and app. Website cookies may also depend on the website platform and its configuration. The app may retain cached content on your device. Deleting the app or clearing its storage may remove that local copy, but does not necessarily delete server records.

2.3 Information we do not intentionally collect

During ordinary use, we do not intentionally request GPS or precise location, camera or microphone recordings, contacts, calendar information, biometric identifiers, or payment-card numbers. You may choose to include personal information in a feedback message or uploaded file; information you submit this way is treated as content you provide.

3. HOW WE USE INFORMATION

We use information to:

1. Create and authenticate accounts, maintain sessions, and secure access.
2. Provide documents, fault codes, diagrams, calculators, troubleshooting, search, uploads, and saved features.
3. Verify subscriptions, promotional access, entitlements, renewals, and fraud or abuse controls.
4. Store and retrieve user content and media, including through hosting and object storage.
5. Respond to feedback, support requests, correction reports, and promotional requests.
6. Send transactional messages such as support replies, promo-code delivery, account or service notices, and security notices. We do not currently send unsolicited marketing email as part of the Service.
7. Understand usage, monitor performance, diagnose failures, improve content and features, and maintain reliable operations.
8. Detect, investigate, prevent, and address fraud, misuse, security incidents, violations, and legal claims.
9. Create and preserve EULA acceptance and other business, accounting, audit, and compliance records.
10. Comply with law, enforce agreements, protect rights and safety, and support a merger, financing, acquisition, or other business transfer.

4. SERVICE PROVIDERS AND DATA FLOWS

We disclose information to service providers as reasonably needed to operate and protect the Service. These providers may process information under their own terms and privacy notices.

4.1 Google Firebase and Firebase Authentication

We use Google Firebase and Firebase Authentication to authenticate users, issue and verify UIDs, store and query Service data in Firestore, enforce access rules, and support operational functions. Firebase may process account, device, usage, security, subscription, feedback, legal-acceptance, and other information needed for those functions. Supported builds may also use Firebase App Check and platform security checks to help verify app requests and reduce abuse.

Google’s privacy information is available at https://policies.google.com/privacy.

4.2 RevenueCat

We use RevenueCat to reconcile in-app subscription and entitlement status across platforms and to process promotional entitlement grants. RevenueCat receives identifiers such as the Firebase UID and subscription or entitlement information needed for that purpose. It may process purchase metadata from the platform.

RevenueCat’s privacy information is available at https://www.revenuecat.com/privacy.

4.3 Apple App Store and Google Play

Apple and Google process purchases, billing, payment cards, refunds, and store-account details under their own terms. We receive subscription or entitlement information needed to provide access, not your payment-card number.

Apple’s privacy policy: https://www.apple.com/legal/privacy/
Google’s privacy policy: https://policies.google.com/privacy

4.4 Brevo

Our current server uses Brevo for transactional email, including feedback or support notifications and promotional-code delivery. When an email is sent, Brevo may receive the recipient’s email address, name, message or request content, subject, and delivery metadata.

Brevo’s privacy policy is available at https://www.brevo.com/legal/privacypolicy/.

4.5 Replit hosting and object storage

The Service is hosted and operated using Replit infrastructure. Replit object storage and related storage services may store uploaded documents, captures, images, videos, and other media according to the feature and access controls. Replit and its infrastructure providers may process content, account, technical, and operational data to host, secure, back up, and deliver the Service.

Replit’s privacy information is available at https://replit.com/site/privacy. Do not upload content you are not authorized to store.

4.6 Document-search providers (Google and Exa)

When you search for a manufacturer document in the app, the text you type in the search box is sent to Google Programmable Search and, when needed, to Exa (exa.ai), two third-party web search services, to find publicly available manufacturer documents. Only the search text is sent. We do not send your name, email address, account identifier, location, or device identifiers to these providers. Before your first web search, the app explains this and asks you to continue or cancel; if you cancel, only the in-app document library is searched. You can change this choice on the Document Library screen at any time. Do not include personal or customer information in a search. We use these providers only to return search results, and they process search text under their own privacy policies, which provide protection for this data equal to or greater than this Policy: Google – https://policies.google.com/privacy; Exa – https://exa.ai/privacy-policy.

4.7 No AI model providers

Ductless Master does not currently include an AI assistant and does not send your information to AI model providers such as OpenAI. If we add such a feature, we will update this Policy and ask for your permission in the app before any of your information is sent to that provider.

4.8 Vimeo

When you play a Vimeo-hosted video in the Service, your device connects to Vimeo’s player. Vimeo may receive connection, device or browser, and playback information, and may use cookies or similar technologies according to its own settings and policies.

Vimeo’s privacy information is available at https://vimeo.com/privacy.

4.9 Wix website hosting

Our public website, including this Policy page, is hosted by Wix. When you visit the website, Wix may process standard connection, device or browser, cookie, and technical information needed to serve, secure, and operate the site. If you submit information through a Wix-hosted form, Wix may process the information you enter to deliver that submission to us.

Wix’s privacy information is available at https://www.wix.com/about/privacy.

5. SHARING AND DISCLOSURE

We do not sell personal information and do not currently share it for cross-context behavioral advertising. We may share information:

• With the providers and platforms described in Section 4, as needed to operate the Service.
• With contractors, professional advisers, auditors, insurers, and other vendors working for our business.
• When you direct us to share information or otherwise consent.
• To comply with a subpoena, court order, law, regulation, or lawful government request.
• To protect the rights, property, security, or safety of HVAC Pocket Pro, users, providers, or the public, or to investigate fraud and abuse.
• In a merger, acquisition, financing, reorganization, bankruptcy, sale of assets, or similar transaction. When reasonably practicable, we may provide notice through email or an in-app or website notice.

We may use aggregated or de-identified information that does not reasonably identify you for analytics, security, reporting, and improvement, and may retain it as permitted by law.

6. RETENTION

We retain information for as long as reasonably needed for the purposes in this Policy, our business operations, security, dispute resolution, and legal obligations. Current baseline periods are:

• Anonymous user session and operational records: up to 12 months from last activity, unless needed for security, legal, or aggregate purposes.
• Feedback submissions: until you request deletion or for 2 years, whichever comes first, except records needed for security, legal, or dispute purposes.
• Promotional request records: 2 years.
• Subscription and entitlement status: duration of the subscription plus 1 year, subject to provider records and legal needs.
• Analytics and performance data: according to applicable provider defaults and configuration, currently potentially up to 14 months.
• EULA acceptance records: account lifetime plus 7 years.

6.1 Deletion and legal retention

You may request deletion of personal information by contacting info@hvacpocketpro.com. We will review and respond as required by applicable law. We may retain information that we must or may keep for legal compliance, fraud prevention, security, accounting, tax, dispute resolution, exercise or defense of legal claims, or the EULA acceptance-retention period above. In particular, deleting an account or other personal information does not automatically delete the legal acceptance record retained for the account lifetime plus 7 years. We may de-identify or securely isolate retained information and delete it when the applicable retention need ends.

Provider, store, backup, and legal records may persist for a limited period after our deletion action under their own retention schedules. We cannot delete information you voluntarily submitted to another user or third party from that party’s systems.

7. YOUR RIGHTS AND CHOICES

Depending on where you live and subject to legal exceptions, you may request access to, correction of, deletion of, or a copy of personal information we hold about you. You may also ask about processing, object to or restrict certain processing, or request that we exclude your information from optional analytics where we can do so. You may manage a store subscription through Apple or Google and control some device permissions through your device settings.

Send a request to info@hvacpocketpro.com, preferably from the email associated with your account. We may ask for information reasonably needed to verify the request and protect your account. We will not use verification information for an unrelated purpose. Where applicable law permits, you may use an authorized agent, subject to verification. We do not discriminate against you for exercising a privacy right. If we deny a request, we will explain the reason and any appeal or regulator option required by applicable law.

7.1 California residents

If California law applies, California residents may have rights to know or access, correct, delete, and obtain portability of personal information, and to limit certain uses of sensitive personal information. California residents may also have the right to opt out of the sale or sharing of personal information for cross-context behavioral advertising. We do not sell personal information or currently share it for cross-context behavioral advertising. We do not knowingly use sensitive personal information to infer characteristics.

To submit a request, contact info@hvacpocketpro.com. We may verify requests as required by law and will not discriminate against you for exercising your rights.

8. CHILDREN AND AGE

The Service is not directed to anyone under 18. We do not knowingly permit a person under 18 to use the Service or knowingly collect personal information from one. If we learn that a person under 18 has provided information, contact us at info@hvacpocketpro.com. We will take reasonable steps to investigate and delete it where required, subject to legal retention and safety obligations.

9. SECURITY

We use reasonable technical and organizational measures appropriate to the information and risks, including HTTPS/TLS transmission, access controls, server-side authentication checks, Firebase security rules, restricted administrative access, and provider safeguards. No transmission, storage system, or email is completely secure, and we cannot guarantee absolute security.

If you suspect unauthorized access or a security issue, contact info@hvacpocketpro.com. Do not send passwords or other secrets.

10. INTERNATIONAL AND GEOGRAPHIC PROCESSING

HVAC Pocket Pro is based in Illinois, United States. Our providers may process information in the United States or other locations where they or their subprocessors operate. Those locations may have privacy laws different from your own. We use safeguards and contractual arrangements made available by applicable providers and law, but no transfer method eliminates every risk.

11. CHANGES TO THIS POLICY

We may update this Policy as the Service, providers, or legal requirements change. We will post the revised Policy and update the “Last updated” date. For material changes, we may provide an in-app notice, email, or other reasonable notice. If a change requires consent, we will request it before the affected processing where required.
