Terms of Service
Last updated: August 11, 2026
1. Preamble
These Terms of Service ("Terms") govern the relationship between you ("User", "you") and I. Angelov ("Provider", "we") regarding the use of the CuttingOpt.Pro service ("the Service"), available at https://cuttingopt.pro/.
By registering or using the Service you accept these Terms. If you do not agree, please do not use the Service.
2. Service description
CuttingOpt.Pro is an online calculator for optimizing material cutting (stocks → cuts). The Service offers:
- Free plan with basic features and a monthly limit
- Paid plans (Hobby, Pro) with extended features
Full feature description per plan is published on the homepage.
3. Registration and account

3.2 User responsibilities

3.3 One account per person
Creating multiple accounts to circumvent limits is not permitted.
4. Acceptable use
The following are prohibited:
- Performing illegal actions through the Service
- Attempting to compromise the server, other accounts, or security
- Automated use beyond reasonable limits (scraping, botting)
- Reselling or redistributing without written permission

5. Paid plans
5.1 Pricing
Current prices are listed on the site. We reserve the right to update prices for new subscribers; existing subscriptions retain their price until the end of the current period.
5.2 Auto-renewal
Monthly and annual subscriptions auto-renew. You can cancel at any time via the Stripe Customer Portal or via "Delete account".
5.3 Right of withdrawal (EU consumer law)
Pursuant to EU Directive 2011/83/EU on consumer rights, you have the right to withdraw from the contract within 14 days of conclusion, WITHOUT giving reasons and WITHOUT penalty.
Important: By confirming at checkout that you start using the service immediately, you agree that the right of withdrawal lapses for the portion already used. The right remains for the unused portion.
5.4 Refund policy
- Erroneously charged payments → full refund promptly
- Technical issue caused by us (downtime > 24 hours) → pro-rated refund
- Change of mind → no refund; cancelling the subscription (see 5.2) stops future charges
Refund requests: cuttingopt.pro@gmail.com
5.5 "Lifetime" plan
"Lifetime" means a one-time payment for access with no recurring fees for the lifetime of the CuttingOpt.Pro service — not "forever" in a literal sense. Software services depend on technologies, infrastructure and third-party providers (hosting, payment systems, browser standards) whose availability cannot be guaranteed indefinitely.
We guarantee access to the service and the included Pro features for a period of at least 5 (five) years from the date of purchase. After that period we will make reasonable efforts to keep the service running unchanged, but we do not undertake an indefinite guarantee — the service may be modified, merged with another product or discontinued due to technological obsolescence, economic non-viability or cessation of business. Discontinuation after the guaranteed period does not give rise to a refund of the one-time payment.
6. Termination
6.1 By you
At any time via "Delete my account". Paid subscriptions continue until the end of the paid period; no refund for unused portion except as in 5.4.
6.2 By us
We may terminate your access in case of:
- Violation of these Terms
- Unpaid invoices > 30 days
- Service discontinuation (with 60-day notice)
7. Intellectual property
7.1 Our property
The source code, design and CuttingOpt.Pro brand are our intellectual property.
7.2 Your property
Data you input (stocks, parts, projects) remains entirely yours. We make no claim to it. You may export or delete it at any time.
7.3 License to us
You grant us a limited license to process your data solely for the purpose of providing the Service. We do not share, sell, or analyze beyond this.
8. Disclaimer and limitation of liability
8.1 Service provided "as is"
We do not provide guarantees for:
- 100% uptime
- Error-free cuts
- Fitness for a particular purpose
8.2 Limitation of liability
To the maximum extent permitted by law, our liability is limited to:
- The amount you paid in the last 12 months, or
- EUR 100 — whichever is greater
Under no circumstances are we liable for:
- Indirect damages (loss of profits, data loss outside our fault)
- Errors in actual cutting due to reliance on our calculations
⚠️ IMPORTANT: Always verify results before actual cutting. CuttingOpt.Pro is an auxiliary tool, not a substitute for professional judgment. We are not liable for lost materials or errors in actual production.
9. Changes to terms
For material changes we will notify registered users via email at least 30 days in advance. Continued use after the effective date constitutes acceptance.
10. Governing law and disputes
These Terms are governed by Bulgarian law. Disputes that cannot be resolved amicably are referred to:
