Terms & Policies

1. Agreement to these terms

MapMath (“the Guide,” “we,” “us”) is operated by Umar Farooq, based in Lahore, Pakistan. By accessing this website, purchasing access, or downloading the PDF, you agree to be bound by these terms. If you do not agree, do not use the site or buy the Guide.

2. What you are buying

A single payment grants you a personal, non-exclusive, non-transferable licence for lifetime access to all chapters of the Guide and to download the accompanying PDF. “Lifetime” means the operational lifetime of the product and is not a guarantee of perpetual availability.

• The licence is for your individual use. You may not share, resell, sublicense, or publicly redistribute the chapters or the PDF.
• Code listings are yours to use. You may use the code examples freely in your own projects, commercial or otherwise, without attribution.
• For team, classroom, or bulk licensing, contact us before distributing to additional people.

3. Payment and access

Prices are listed in US dollars. Payments are processed manually through the methods offered at checkout (e.g. Wise, PayPal, or bank transfer). Access is granted to the email address associated with your purchase once payment is confirmed. If you sign up with the same email after paying, your access is unlocked automatically. If access does not appear within a reasonable time, contact us and we will resolve it.

4. Refund policy

We offer a 30-day refund, no questions asked. If the Guide isn’t for you, email us within 30 days of purchase and we will refund you in full through the same channel you paid with. After 30 days, refunds are at our discretion.

5. Accuracy, errata, and disclaimer of warranties

The Guide is provided for educational purposes. While it has been prepared with care, the formulas, code, and other content are provided “as is” and “as available,” without warranties of any kind, whether express or implied, including but not limited to the implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement.

Mapping and geospatial mathematics involves edge cases, differing datums, and platform-specific behaviour. You are responsible for independently verifying any formula or code against your own requirements before relying on it in production or in any safety-, navigation-, or financially-sensitive system.

We maintain the Guide and welcome corrections. If you find an error, email you@mapmath.dev. Confirmed corrections are credited and rolled into a future revision.

6. Limitation of liability

To the maximum extent permitted by law, in no event shall Umar Farooq or MapMath be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, data, or goodwill, arising out of or in connection with your use of (or inability to use) the Guide, even if advised of the possibility of such damages. Our total aggregate liability for any claim relating to the Guide shall not exceed the amount you paid for it.

7. Intellectual property

All text, diagrams, branding, and design of the Guide and this website are the property of Umar Farooq and are protected by copyright, except for the code listings, which you are licensed to use as described in section 2. You may not reproduce or redistribute the written content without prior written permission, other than brief quotations in a review.

8. Privacy

We collect only what we need to deliver the Guide: your name and email (via our authentication provider) and your order details. We use this to grant access, process payments and refunds, and respond to support requests. We do not sell your personal information. Account and order data is retained for as long as needed to provide access and meet legal obligations.

9. Changes to these terms

We may update these terms from time to time. The current version is always posted on this page with the “last updated” date above. Continued use of the site after changes take effect constitutes acceptance of the revised terms.

10. Governing law

These terms are governed by the laws of Pakistan, without regard to its conflict-of-law provisions.
