Terms of Service

Application: Constructor Estimator (com.orbittechlab.constructorestimator)
Developer: Orbit Tech Lab
Effective Date: January 1, 2026 · Last Updated: November 2026
Important Engineering Disclaimer: Constructor Estimator provides preliminary estimates for budgeting, planning, and material rule-of-thumb calculations. Calculations are not a substitute for professional architectural, structural engineering, or geotechnical consultation. Always have your structural drawings and material specifications stamped and approved by a licensed engineer prior to physical procurement or construction work.

1. Agreement to Terms

By downloading, installing, or using the Constructor Estimator mobile application (the "App"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree with any part of these Terms, do not install or use the App.

2. Description of the Service

Constructor Estimator is an offline Android mobile application designed to assist property owners, contractors, and builders in estimating plot area conversions (Marla, Kanal, Square Feet, Square Yards), construction quantities (brick counts, cement bags, sand volumes, aggregate volumes, steel rebar tonnage), and contractor quote comparisons.

3. Intellectual Property Rights

The App, including its visual design, layout, calculation algorithms, formulas, branding, graphics, and source code, is the proprietary property of Orbit Tech Lab and is protected by copyright, trademark, and intellectual property laws. You may not reverse-engineer, decompile, distribute, resell, or create derivative works from the App without prior written consent from Orbit Tech Lab.

4. Accuracy of Calculations & Limitations

While every effort has been made to incorporate standard civil engineering ratios (such as standard mortar ratios, wet-to-dry conversion factors of 1.54 for concrete, and standard rebar density formulas):

  • Material consumption on actual job sites varies due to ground conditions, contractor workmanship, soil bearing capacity, structural design variations, wastage factors, and local building codes.
  • Unit material prices (such as cement per bag, brick rates, and steel per kg) are based on user inputs and regional market volatility. Users are responsible for confirming actual market pricing with suppliers before entering contractual agreements.
  • Orbit Tech Lab does not guarantee that actual job-site expenditures will match calculations generated by the App.

5. Limitation of Liability

To the maximum extent permitted by applicable law, Orbit Tech Lab and its developers, contractors, and agents shall not be liable for any direct, indirect, incidental, consequential, special, or exemplary damages arising out of or in connection with your use or inability to use the App. This includes, without limitation, damages for cost overruns, construction delays, structural failures, material shortages, or procurement inaccuracies.

6. User Responsibilities & Acceptable Use

You agree to use the App solely for lawful purposes. You agree not to:

  • Use the App to produce fraudulent contractor bids or deceptive construction records.
  • Attempt to tamper with, modify, or inject malicious code into the App binaries.

7. Offline Storage & Backup

The App stores project information locally in your device's private sandbox. You acknowledge that if you delete the App or wipe your device storage without exporting your Bill of Quantities (BOQ) PDF reports, your project data cannot be recovered by Orbit Tech Lab.

8. Termination & Modification

Orbit Tech Lab reserves the right to modify, suspend, or discontinue the App or any part thereof at any time. We also reserve the right to revise these Terms at our discretion. Changes will take effect upon posting to this page.

9. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the jurisdiction where Orbit Tech Lab operates, without regard to its conflict of law principles.
