Privacy Policy

1. Introduction

QuantX Takeoff ("the Service") is a construction takeoff and quantity-measurement application provided by Nomitech LTD ("we", "us", "our"). The Service consists of a web application at quantx.nomitech.com, the QuantX Takeoff add-in for Microsoft Excel, which links worksheet cells to live measurement data, and the QuantX Takeoff apps for iPhone and iPad, for Android, and for Windows and Mac ("the apps").

This Privacy Policy explains what information the QuantX Takeoff Service, add-in and apps collect, how we use and protect it, and the choices and rights you have. It applies to the Service, the add-in and the apps specifically — not merely to our marketing website. By installing or using QuantX Takeoff, you agree to the practices described here.

2. Information we collect

2.1 Account & authentication data

When you sign in to QuantX Takeoff (via our single sign-on provider), we process your name, email address, organization/tenant membership, role, and authentication identifiers and session tokens. We do not receive or store your password in plain text; authentication is handled by our identity provider.

Accounts are by invitation only: a company administrator invites the users of the company's workspace, and trials are by invitation too. There is no self sign-up. Signing in with Google, Apple, Microsoft or Facebook works only for an email address that has been invited; the provider then shares your name and email address with us.

2.2 Project & takeoff content

To provide the Service, we process the content you create or are authorized to access, including construction drawings and documents, measurements and measurement groups, templates, bills of quantities, notes, and the quantities, units, and titles displayed in Excel.

2.3 Workbook link metadata

To keep your cells linked, the add-in stores small settings inside your Excel workbook — such as the server URL, a read-only share token, the project identifier, and the cell-to-measurement links. This information lives in your workbook file.

2.4 Usage & technical data

We automatically collect technical information such as IP address, browser and Office host type (e.g., Excel for Windows, Mac, or the web), device and operating-system information, log and diagnostic data, timestamps, and feature-usage events. We do not use this data to build advertising profiles.

2.5 Mobile apps (iPhone, iPad and Android)

The QuantX Takeoff apps for iPhone, iPad and Android also process the following, and only when you use the feature concerned:

• Photos and scanned documents — photos you take with the camera and documents you scan, when you choose to upload them to a project.
• Room scans — on an iPhone or iPad with a LiDAR sensor, the rooms you scan with Apple RoomPlan, uploaded to your project as drawings.
• Microphone and speech — when you ask a question by voice, your speech is turned into text on your device where possible, and otherwise by your device's speech recognition service (Apple's, on iPhone and iPad). We receive only the text; we do not store the audio.
• Notification token — if you allow notifications, your device's push notification token is stored with your user account so that we can deliver notifications to it. It is removed when you sign out on that device or delete your account.
• Drawings on your device — drawings you open or keep for offline use are cached on your device, so that they open quickly and also work without a connection.

The apps show no advertising, do not track you across other companies' apps or websites, and do not collect your location. We do not sell your data.

2.6 Desktop app (Windows and Mac)

The QuantX Takeoff desktop app for Windows and Mac gives you the same Service as the web application. In addition:

• Local settings — the app keeps a small settings file on your computer with the server you chose and the window's size and position.
• Update checks — the app asks our server whether a newer version is available, sending the app's version number.
• App version — the app's version is included in the user agent of the requests it sends to the Service.
• Sign-in — signing in may open your computer's web browser; you sign in there and are then returned to the app.

The desktop app sends no telemetry and no crash reports.

3. How we use information

• To authenticate you and authorize access to your organization's projects;
• To display live measurement values, units, titles, and drawing previews in Excel via the =CELLBIM functions;
• To maintain links between cells and measurements and keep linked values current;
• To process drawings and generate measurements (including optional AI-assisted features — see §5);
• To provide customer support and respond to your requests;
• To maintain security, prevent fraud and abuse, and ensure service integrity;
• To analyze usage and improve performance, reliability, and features;
• To comply with legal obligations and enforce our Terms of Service.

4. Read-only share tokens

Workbooks exported from QuantX Takeoff may embed a read-only share token so colleagues can view live values and drawings without signing in. The token grants read-only access to that project's measurements and drawings only. Treat exported workbooks like any document that contains project data, and share them accordingly. Authorized users can revoke tokens at any time from the QuantX Takeoff web app.

5. AI features & sub-processors

Certain optional features process your drawings and project data through trusted third-party sub-processors that act on our behalf:

• Document conversion & rendering — to convert and render uploaded drawings for viewing and measurement.
• AI object detection — to detect rooms, walls, and other elements in drawings when you use automated detection.
• AI measurement generation — large-language-model providers used to assist with AI-Vision measurement features when you invoke them.
• Microsoft — distribution of the add-in through Microsoft AppSource and the Office platform.
• Apple, Google and Microsoft — distribution of the apps through the App Store, Google Play and the Microsoft Store, and Apple's push notification service for notifications on iPhone and iPad.

We share only the data necessary to perform these functions, and we require sub-processors to protect it. AI-assisted features run only when you choose to use them.

When you use the AI features — the AI assistant (Ask), AI takeoff, object detection and questions about your documents — your question, the project or drawing data needed to answer it and any photos you attach are sent to our AI processing providers:

• Language and vision model providers — third-party providers such as OpenAI, Anthropic and Google, which write the answers and read drawings, documents and photos.
• Drawing recognition — our own BimCT services and Togal.AI, which recognise rooms, walls, symbols and other elements on drawings.

These providers act as our processors under contract and use the data only to produce the answer or result for you. We use providers whose terms do not allow them to use this data to train their models.

The apps ask for your consent before your data is first sent to an AI provider. You can withdraw your consent at any time in the app's settings.

6. Microsoft 365 & Office scope

The add-in runs inside Microsoft Excel via the Office Add-ins platform. It accesses only the workbook content needed to read and write the linked cells you choose, together with the data you are authorized to access in QuantX Takeoff. It does not access other documents or files on your device.

7. Storage & international transfers

The Service is hosted on servers located in the United States. If you access QuantX Takeoff from the European Economic Area, the United Kingdom, or another region, your information will be transferred to and processed in the United States. Where required, such transfers are made under appropriate safeguards, including Standard Contractual Clauses with our processors.

8. How we share information

We do not sell your personal information. We share information only: (a) with the sub-processors described in §5 to operate the Service; (b) when required by law, regulation, or valid legal process; (c) to protect the rights, safety, and security of our users and the Service; and (d) in connection with a merger, acquisition, or sale of assets, subject to this Policy. Your project data stays within your organization's tenant and is accessible only to authorized users (or via a share token you create).

9. Data retention

We retain your account and project data for as long as your organization maintains its account or as needed to provide the Service. When you delete content or close your account, we delete or anonymize the associated data within a commercially reasonable period, except where retention is required for legal, accounting, or security purposes. Link metadata stored inside a workbook remains in that file until you remove the links or delete the file.

9.1 Deleting your account

You can delete your account yourself in the mobile apps (More → Delete account), or ask us to delete it at support [at] nomitech.com. Deleting your account:

• removes your profile, your preferences, your notification devices, your sessions and your entries in the activity log;
• leaves your company's projects with your company: they belong to it, and their ownership passes to a company administrator;
• if you are the only member of your company, also deletes the company's workspace and its projects (the app warns you first). This is not possible while the company has a paid plan: the plan must be cancelled first;
• also deletes your sign-in account at our sign-in service, unless you use it for other Nomitech LTD products.

A company workspace with several members is closed as a whole by its administrator, who asks us through support.

10. Your rights

Depending on your location, you may have the right to access, correct, delete, restrict, or object to the processing of your personal data, and to data portability. To exercise any of these rights, contact us at support [at] nomitech.com or through your organization's account administrator. We will respond within the timeframe required by applicable law. You may also have the right to lodge a complaint with your local data-protection authority.

11. Cookies & local storage

QuantX Takeoff uses essential cookies and browser local storage to keep you signed in (for example, storing your authentication token) and to remember your preferences. These are necessary for the Service to function. We do not use them for third-party advertising.

12. Security

We protect your data with industry-standard measures, including encryption in transit (TLS/HTTPS), access controls, and logical isolation of each customer's (tenant's) data. No method of transmission or storage is completely secure, but we work continuously to safeguard your information.

13. Children

QuantX Takeoff is a professional tool intended for business use and is not directed to children. We do not knowingly collect personal information from anyone under the age of 16.

14. Changes & contact

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Last updated" date above and, where appropriate, by notice within the Service. Your continued use of QuantX Takeoff after an update constitutes acceptance of the revised Policy.
