Privacy Policy
Last updated: 14 October 2026
QTac (Quantity Takeoff) is desktop software from Brainquisitive Merits, India ("we", "us"). It is designed so that your work stays on your computer. This policy explains the little personal data we do collect, why, and your rights under India's Digital Personal Data Protection Act, 2023.
What stays on your computer
- Drawings you open (PDF, DXF, DWG), measurements, quantities, project files and Excel exports. QTac never uploads them.
- Your Item Library, layer profiles and automatic recovery copies, kept in your Windows user profile.
What we collect
- When you register: your name and email address, any optional details you choose to give (mobile number, organisation, city), whether you agreed to news emails, a random identifier for this installation and the QTac version number.
- When you buy or renew: your name, email and this computer's installation code, so we can issue an access code for it. Your card, UPI or bank details go to the payment provider, never to us.
- When you check for updates: nothing but the request itself. No account, no code, no email address.
- When you write to us: your message and email address.
No drawing, project, measurement, quantity or file name is ever sent. QTac contains no advertising, analytics or usage tracking.
Why we use it
- To create and check your account and access to QTac.
- To tell you about important changes: updates, security fixes, changes to these terms, and any move to paid plans.
- To answer your support requests.
- To send news about QTac, only if you agree to it. You can withdraw that consent at any time with the unsubscribe link or by writing to us.
Who else sees it
We do not sell or rent your personal data. Registration details are kept in a Google Sheet in our Google account, and the registration code is emailed through Gmail, so Google processes them for us under its own terms. If paid plans start, a payment provider will handle payments. These providers use the data only to provide their service to us. Payment details go to the payment provider, not to us; its privacy policy applies to them. We disclose data to authorities only when the law requires it.
How long we keep it
We keep your account details while your account is active, and delete them within 90 days after you ask us to, unless the law requires us to keep them longer (for example, invoices).
Your rights
You may ask for a summary of the personal data we hold about you, have it corrected or completed, have it erased, withdraw any consent you gave, and nominate someone to act for you. Write to bqi.support@brainquisitive.com; we reply within 30 days. If you are not satisfied, you may complain to the Data Protection Board of India.
Children
QTac is for professionals and is not intended for anyone under 18. We do not knowingly collect their data.
Changes
We will post changes to this policy in the app, and email registered users about significant changes.
