Policy

Effective Date: October 11, 2026

VentilatePro is operated by Patil Engineers, a sole proprietorship based in Maharashtra, India ("Patil Engineers," "we," "us," or "our"). This Privacy Policy explains what personal information we collect when you use www.ventilatepro.com, the VentilatePro HVAC software, its AI features, the Revit add-in, the command-line tool, the MCP server and our PE practice exams (collectively, the "Services"), how we use it, and the choices you have. It applies to everyone who uses the Services, wherever they live. It complements our Terms and Conditions and Refund and Cancellation Policy.

1. Information We Collect

• Account information: your name and email address, and your Google profile name and email if you sign in with Google.
• Project content: the projects, calculation inputs, Revit and gbXML imports, drawings, documents, notes, attachments and AI conversations you create in or upload to VentilatePro.
• Purchase information: what you bought, when, and the payment status. Card and bank details are entered with our payment processor and are not stored on our servers.
• Usage and device information: your IP address, browser and device type, the pages you visit, and server logs of requests, including requests made by the command-line tool and MCP clients.
• Support messages: what you send us by email, the support form or the in-app bug reporter.

2. Cookies and Similar Technologies

We use cookies that the Services need to work, such as the cookies that keep you signed in and protect forms against forgery, and to remember preferences such as dark mode. We also use Google Analytics, which sets cookies to measure how the site is used, and Google reCAPTCHA, which checks that sign-up and other forms are used by people, not bots. You can block or delete cookies in your browser settings, and you can opt out of Google Analytics with Google's opt-out add-on. Blocking essential cookies will stop you from signing in.

3. How We Use Your Information

• To provide the Services: running calculations, storing your projects, and running AI features when you ask for them.
• To manage your account, purchases and subscription, and to send transactional emails such as receipts, access codes and account notices.
• To answer support requests and fix problems.
• To keep the Services secure, enforce plan limits, and prevent fraud and abuse.
• To understand how the Services are used and improve them, using aggregated analytics.

We do not sell your personal information, and we do not use it for targeted advertising. We do not use your project content to train AI models.

4. Who We Share It With

We share personal information only with service providers that help us run the Services, and only what each needs:

• Hosting and delivery: our cloud hosting providers and Cloudflare, which delivers and protects the website.
• AI model providers: when you use an AI feature, such as Mimir, AI categorization, schedule extraction or an AI drawing review, the content that request needs is sent to the AI model provider that runs it, under that provider's terms for business API use.
• Google: for Google sign-in, Google Analytics and reCAPTCHA.
• Payment processors: such as Razorpay, which process payments and handle your card or bank details.
• Email delivery: our email provider, to send transactional emails.
• GitHub: bug reports you submit from the app are recorded as issues in our GitHub repository.
• Your team: project members you invite can see that project's content.

We may also disclose information when the law requires it, such as in response to a court order, or to protect our rights, our users or the public.

5. Where Your Information Is Processed

We are based in India, and our servers and service providers are located in the United States, India and other countries. Your information may be processed outside the country where you live. Where the law requires it, we rely on safeguards such as our providers' standard contractual terms.

6. How Long We Keep It

We keep your account information and project content while your account is open. When you delete a project or your account, we delete its content from our live systems, and copies in backups are removed on their normal schedule. We keep purchase records for as long as tax and accounting laws require, and server logs for a limited time for security.

7. Your Rights

Wherever you live, you can ask us to:

• Tell you what personal information we hold about you and give you a copy.
• Correct information that is wrong or incomplete.
• Delete your information, except what the law requires us to keep.
• Export your project data in a portable format.
• Stop or limit a use of your information that you object to, and withdraw consent you gave us, such as for analytics cookies.

Email [email protected] from your account email address, and we will respond within 30 days. We will not treat you differently for using these rights.

California and other US states: Residents of California and other states with privacy laws have the rights above, including the right to know, delete and correct personal information. We do not sell or share personal information for cross-context behavioral advertising. You may use an authorized agent to make a request, and you may appeal our decision by replying to it.

European Economic Area, United Kingdom and Switzerland: We process your information to perform our contract with you, for our legitimate interests in running and securing the Services, and with your consent for analytics cookies. You may also complain to your local data protection authority.

India: You may also contact us about a grievance at the email address above, and we will address it as required by Indian law.

8. Security

We protect your information with HTTPS encryption in transit, access restricted to authorized people, and token-based access for the command-line tool and MCP clients. No system is completely secure, so keep your password and access tokens private.

9. Children's Privacy

The Services are for people aged 18 or older. We do not knowingly collect personal information from anyone under 18. If you believe a minor has given us personal information, contact us and we will delete it.

10. Third-Party Links

The Services link to websites we do not control. Their own privacy policies apply when you visit them.

11. Changes to This Policy

We may update this policy as the Services change. We will post the new version here with a new effective date, and tell you by email or in the app when a change is significant.
