Legal & Security Standard

Privacy Policy

Effective Date: July 24, 2026 | Last Updated: July 2026

1. Overview & Single Purpose Statement

This Privacy Policy applies to the Structural Sensei website (structuralsensei.pages.dev) and the Sensei Takeoff Chrome Extension.

Sensei Takeoff is an engineering productivity tool designed exclusively to enable web-based linear, area, and count quantity takeoffs with local export capabilities (Excel BOQ generation). We adhere strictly to the Chrome Web Store Developer Program Policies, including the User Data Limited Use Disclosure.

2. Data Collection & Handling

We believe in total operational data minimization:

  • No Personal Identifiable Information (PII) Tracking: Sensei Takeoff does not harvest, log, or track your personal details, browsing history, keystrokes, or network credentials.
  • Local Measurement Data: All takeoff measurements, coordinate math, scale calibrations, and bill-of-quantities calculations remain strictly on your local device memory or within your browser's local extension storage.
  • Contact Forms: When you submit a custom project inquiry via our website, your name, email, and message are transmitted securely via HTTP POST directly to our email system (wico.pydev@gmail.com) solely to fulfill your service inquiry.

3. Chrome Extension Permissions Justification

Sensei Takeoff requests only the minimal necessary browser permissions required to operate:

activeTab

Used temporarily to inject the visual measurement overlay and canvas calculation interface on the document you are actively taking off.

storage

Used to save your local scale calibration settings and temporary takeoff totals locally on your device so work is not lost across page refreshes.

4. Zero Data Sales & Sharing Guarantee

We do not sell, trade, lease, or monetize user data under any circumstances.

Data collected via the website or saved within the Chrome Extension is never used for targeted advertising, broker transfers, credit evaluation, or third-party tracking.

5. Execution of Code & Security

Sensei Takeoff contains no obfuscated scripts, remote dynamic code execution, or unauthorized background network connections. All execution packages are self-contained within the extension bundle submitted to Google Chrome Web Store review.
