Terms of Service

Last updated 14 October 2026

These terms are the agreement between you and Jehad Abughazaleh, South Africa (“we”, “us”), who runs UMLEdit (“the service”). By using the service you agree to them. If you do not agree, please do not use it.

1. The service

UMLEdit is a UML and diagram editor that runs in your web browser. It has a free plan and a paid plan called Pro. What each plan includes is shown on the pricing page. The marker gives automatic feedback on diagrams; it is a study aid, not an official grade, and your lecturer's marking always decides.

2. Your account

• You need an account only to buy and use Pro or a team seat. Everything in the free plan works without one.
• Use an e-mail address that is yours. We send confirmation codes and notices about your account to it.
• Keep your password and the codes we send you to yourself. You are responsible for what happens under your account.
• An account is for one person. Do not share it or sell access to it.
• You must be at least 13 years old to make an account. If you are under 18 you need the permission of a parent or guardian to buy Pro.

3. Pro, prices and payment

• 1-month pass: $7.99, paid once, Pro for 31 days. Semester pass: $19.99, paid once, Pro for 4 months. Passes do not renew; a new pass adds its time on top of the time left.
• Lifetime: $79, paid once. It is a permanent purchase. “Lifetime” means for as long as the service exists. If we ever have to close the service we will tell account holders at least 90 days before.
• Teams: seats bought through Contact sales, on the price and period agreed in writing. The person who runs the team decides who has a seat; a seat gives Pro to whoever logs in with that e-mail address while the team is active.
• Tax may be added depending on where you live. The final amount is shown before you pay.
• We may change prices for new purchases. A pass or Lifetime you already bought is not affected.

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns.

4. Refunds

A pass that has started and Lifetime are not refunded, except as set out in the Refund Policy, which is part of these terms.

5. Your diagrams

• What you make with the service is yours. We claim no rights to it.
• Your projects are stored in your own browser on your own device. We never receive them and cannot restore them. Export a project file of anything that matters to you, or use your browser's backup.
• When you share a read-only link, the diagram travels inside the link itself; anybody who has the link can open it.
• Live sessions run on the server named in the session, which is not ours unless we say so.

6. Fair use

Do not use the service for anything unlawful, do not try to get around the limits of your plan, do not share or resell accounts or seats, and do not disturb or attack the service. We may suspend or close an account that breaks these terms.

7. Changes and availability

We work to keep the service running and may add, change or remove features. The editor keeps working on your device even when our servers cannot be reached; buying and checking Pro need them.

8. Closing your account

You can stop using the service at any time. To delete your account, open Account in UMLEdit and choose Delete account. This removes it at once and cannot be undone; a pass or Lifetime on it ends with it. Records of payments are kept only as long as the law requires.

9. Liability

The service is provided as it is. As far as the law allows, we are not liable for lost work, lost marks, lost profit or indirect damage, and our total liability to you is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms takes away rights that the law of your country gives you as a consumer and that cannot be set aside by agreement.

10. Changes to these terms

We may update these terms. The date at the top shows the latest version. If a change matters to account holders we announce it by e-mail before it applies.

11. Law

These terms are governed by the law of South Africa, without taking away the protection that the mandatory consumer law of your own country gives you.

12. Trademarks

UML and Unified Modeling Language are trademarks of the Object Management Group. Visual Paradigm, Lucidchart, StarUML, Microsoft Visio, Enterprise Architect, draw.io and other names are the trademarks of their owners; UMLEdit is not affiliated with them and names them only to say which files it can make for them.
