Terms of use

Last updated 4 October 2026

Graspline is an engineering graphics tutor run by Sharmin Sirajudeen. By using it you agree to these terms. They are short on purpose: read them once and you know where you stand.

1. What Graspline is for

Graspline draws engineering graphics questions step by step and explains each line, for your own learning and for teaching. It is free while we test it. Some features may become paid later; we will say so clearly before anything costs money, and founding members will hear first.

If you are under 18, please use Graspline with a parent or guardian's OK.

2. What you may not do

• Copy, download in bulk, or republish Graspline's code, drawings, explanations or design, except a drawing you made for your own study or class.
• Reverse-engineer, decompile, de-minify or otherwise try to extract how the engine works, or use it to build a competing product.
• Scrape it, or send automated requests to it (bots, scripts, crawlers), or try to get around its limits.
• Resell or rent access to it, or remove the copyright notice.
• Use it to break your institution's exam rules. Graspline is a tutor, not a way to sit an exam for you.

3. Your questions and notes

What you type stays yours. You let us use it only to read and draw your question, and, if you agreed to share how you use Graspline, to improve it, exactly as the notice in the app describes. You can ask us to delete it any time at graspline@drengr.dev.

4. Check the drawings

Every drawing is checked against the facts you confirmed before it is shown, and a question it cannot read or draw is refused rather than guessed. Even so, Graspline is a study aid: compare it with your textbook and your teacher's method. It is provided as it is, and to the extent the law allows, we are not responsible for marks, grades or any loss that comes from relying on it.

5. Who owns Graspline

Graspline, its engine, drawings, explanations and design are copyright (c) 2026 Sharmin Sirajudeen. All rights reserved. Its typeface is used under the SIL Open Font License. Graspline is not affiliated with any university or examination board.

6. Changes

We may update these terms as Graspline grows. The date at the top always shows the latest version; if a change matters to you, we will say so in the app or by email.

7. Law

These terms are governed by the laws of India.
