Policies

Terms and conditions

In force from 28 October 2026

These terms apply when you use the CADSECTION software (CADSECTION Studio and the CADSECTION plug-in for AutoCAD), this website and the CADSECTION account, licence and AI services, and when you buy any of them. CADSECTION is developed and sold by Ramkrishna Barman, an individual software developer, Sajherpar Ghoramara, Cooch Behar, West Bengal – 736165, India ("we", "us"). By creating an account, starting a trial or paying, you agree to these terms. If you buy for an office or a firm, you agree to them for it.

The use of the software itself is governed by the End User Licence Agreement (EULA), which you accept in the installer and when you create an account. These terms cover accounts, buying, payments and renewals; where the two differ about the use of the software, the EULA applies. We keep a record of each acceptance (the version, the date and time, your internet address and the program or browser used) as evidence.

1. The licence

When you pay for a plan, we give you a non-exclusive, non-transferable right to install and use CADSECTION on one PC for the period you paid for, on the conditions of the EULA. Plans run for one year, three years or – for the Standard plan only – Lifetime. "Lifetime" means 15 years from the day of purchase, paid once; it is not renewed and ends after those 15 years. The software stays ours; you buy the right to use it, not the software itself. In short:

  • The licence can be moved to another PC a limited number of times a year (twice on Standard and Pro, four times on Pro Max). More moves need our approval.
  • CADSECTION needs you to sign in to your account, and checks the licence with our server from time to time. A paid licence keeps working for up to 15 days without internet; a trial for 1 day.
  • A licence is tied to the PC through five hardware identifiers. When three or more of them change or cannot be read (for example on another computer), the licence has to be moved to that PC, which counts as one of the moves.
  • You may not copy, share, rent or resell a licence, or use one licence on more PCs than it allows.
  • You may not reverse-engineer, decompile, modify or crack the software, remove its licence checks, or help anyone else do so, except where Indian law expressly allows it.
  • Files exported by CADSECTION carry a small hidden mark with the licence number and date, so that a copy made with a misused licence can be traced.

2. The free trial

The trial lasts 14 days, has every feature, and is free. Drawings and PDFs made in the trial carry a TRIAL mark. There is one trial per person and per PC; trials are not available in virtual machines. When the trial ends, CADSECTION does not open until you buy a plan; your project files stay yours and remain on your PC. The same applies when a paid plan ends and is not renewed.

3. Your account and the download

An account needs your name, mobile number and e-mail address, and your acceptance of the EULA, these terms and the privacy policy. You sign in with one-time codes sent to you; there is no password. Keep your details correct and do not let others sign in to your account. You are responsible for what is done with your account. You must be 18 or older to create an account.

The installer (64-bit or 32-bit) is downloaded from the website by signed-in account holders. Do not pass the installer or a download link to others; each download is recorded with the account that made it.

4. Prices and payment

  • Prices are in Indian rupees and are shown on the pricing page. Prices are in Indian rupees and are the full amount you pay.
  • Payments are processed by Razorpay Software Private Limited. We do not receive or store your card, UPI or bank details.
  • We may change prices. A change never affects a period you have already paid for; for a renewing plan, we tell you at least 15 days before a renewal at a new price.
  • A Lifetime plan (Standard, 15 years from the day of purchase) is paid once. Its price is lower than fifteen yearly payments; it includes the updates and support of the Standard plan for the whole 15 years and the PC moves of the Standard plan in each of those years.
  • If a payment fails or is reversed, the plan or credits bought with it may be withdrawn.

5. Plans that renew every year

If you choose "renew every year", Razorpay charges the same price each year on the date your plan started, until you cancel. You can cancel at any time before a renewal by writing to us (see contact us); the plan then stays active until the end of the year already paid for, and no further charges are made. Refunds of renewals are covered in the cancellation and refund policy.

6. AI credits and the Copilot

  • The AI Copilot uses AI credits. Each request uses credits according to its size; CADSECTION shows the credits used and left after each answer. Credits included in a plan are given at the start of each plan year; credit packs are valid for 12 months from purchase. Unused credits expire at the end of their validity and have no cash value.
  • Plans have a daily limit of AI requests. We may limit, queue or pause the AI service for a time to protect it; the rest of CADSECTION keeps working.
  • AI answers can be wrong. Nothing changes in your project until you apply a proposal, and you must check the result.
  • Do not use the Copilot for anything other than work with CADSECTION, and do not try to get around its limits.

7. Your data and your drawings

Your projects, survey data, drawings and reports are yours. They are stored on your PC, not on our server, except what you send to the AI Copilot or to us for support. How we handle personal data is set out in the privacy policy.

8. Updates and support

Updates and support by e-mail and phone are included for the period you paid for (for a Lifetime plan, the 15 years). We aim to keep CADSECTION working on current versions of Windows and AutoCAD, but we may change or remove features over time.

9. Engineering responsibility

CADSECTION is a tool for preparing drawings and quantities. You remain responsible for checking every drawing, level, design and quantity before it is used for construction, measurement or billing, and for meeting the standards and instructions that apply to your work.

10. Warranty and liability

We provide CADSECTION with reasonable skill and care, but we do not promise that it is free of errors or that it will run without interruption. To the extent the law allows, our total liability for any claim connected with CADSECTION is limited to the amount you paid us in the 12 months before the claim, and we are not liable for loss of profit, loss of data, or indirect or consequential loss. Nothing in these terms limits a liability that cannot be limited under Indian law, including your rights under the Consumer Protection Act, 2019.

11. Suspension and ending

We may suspend or end a licence or an account that is used against these terms, for example a shared or cracked licence or misuse of the AI service. We tell you why, by e-mail, where we can. You can stop using CADSECTION and ask us to close your account at any time.

12. Changes to these terms and their transfer

We may update these terms. The date at the top shows the version in force. Important changes are announced on this website or by e-mail before they apply to you, and CADSECTION or the website asks you to accept them.

We may transfer these terms, and our rights and obligations under them, to a company we set up to carry on the CADSECTION business or to a successor, by notice on this website or by e-mail; your plans, credits and rights continue unchanged.

13. Law and disputes

These terms are governed by the laws of India. Please write to us first so that we can try to resolve any problem. Disputes that cannot be resolved are subject to the courts at Cooch Behar, West Bengal.
