These terms cover your use of the hosted livediagram service at livediagram.app (the "Service"), operated by the livediagram team ("we", "us"). By using the Service you agree to these terms. If you do not agree, please do not use the Service. They work alongside our Privacy Policy, which explains what the Service does with your data.
The software is open source
livediagram's source code is public and MIT-licensed. You are free to read it, fork it, and run your own copy. These terms govern only the hosted Service we operate at livediagram.app. They do not apply to a copy you host yourself, which is yours to run (see Self-Hosting).
Using the Service
You can create and edit documents without an account. Some features, such as syncing across devices, may ask you to sign in. You are responsible for the activity that happens under your account and for keeping your sign-in details secure.
Your content
You own the documents and content you create. We do not claim ownership of it. You grant us the limited permission we need to store, process, and display your content so that we can provide the Service to you and to the people you share it with. You are responsible for the content you create and for making sure you have the right to use anything you add to a document.
Sharing
When you create a share link, anyone with that link can open the document, an editor link lets them change it, and a participant link lets them add stickies, comment and vote. You decide who to give a link to, and you can revoke a link at any time. You can also protect a link with a password or give it an expiry. Treat share links like keys. See Share Link Security.
Sharing to the Community
The Community is a public gallery. When you share a document to it (see Sharing to the Community):
- It becomes public. Anyone, with or without an account, can find it, view it read-only and make their own copy of it. Copies people make are theirs, and they stay theirs if you later remove your post.
- It stays live. The Community shows the document's latest saved version, so later changes you, or anyone with an edit link to it, make are public too. Its document and tab names are shown along with your title and description.
- You choose how you are credited. Posts are anonymous unless you turn that off, in which case your display name and profile picture are shown with it.
- You give us permission to show it publicly in the Community and in places that point to it, such as the livediagram home page, for as long as it is shared. You still own it, and you can remove it at any time, unless it has been hidden after reports.
- Only share what is yours to share. You must have the right to publish everything in the document, and it must not contain anyone's personal information without their permission. The acceptable-use rules below apply, and in addition Community posts must not be spam, advertising, or offensive, hateful, sexual or violent content.
Anyone can report a post. A post that several people report is hidden automatically and for good; nobody reviews posts by hand, and a hidden post can't be edited, removed or listed again. We may still take down a post where the law requires it. If you believe a post infringes your copyright or other rights, report it, or contact us using the details below.
API access
You can create API tokens to use the Service programmatically. A token acts as your account: anyone who holds it has the same access to your documents that you do. Keep tokens secret, treat them like a password, and revoke any that might have been exposed. You are responsible for activity carried out with your tokens. We may apply rate limits to keep the Service healthy, and the acceptable-use rules below apply equally to anything you do through the API. If you connect a third-party or AI tool to your account, you authorise it to act for you with that access; you can disconnect it at any time by revoking its token.
Communications
If you have an account, we may send you account and service emails (such as team invitations, a confirmation when you delete your account, and a reminder before an API token expires), notifications about activity on your documents, and a short onboarding series. You can turn off the notifications and onboarding emails in Settings. These help you use the Service; we do not send advertising. See the Privacy Policy for what we send and the provider we use.
Acceptable use
Do not use the Service to:
- break the law or infringe someone else's rights;
- store or share malicious, harmful, or illegal content;
- attempt to disrupt the Service or gain unauthorised access to it or its infrastructure;
- abuse the Service in a way that degrades it for other people.
Good-faith security research that follows our Reporting a Vulnerability policy is authorised and does not breach these rules. Please report anything you find privately, as that policy describes.
Availability and changes
We work to keep the Service running, but we provide it "as is" and "as available", without warranties of any kind. We may change, suspend, or discontinue any part of the Service, and we may update these terms. If we make significant changes we will update the date at the top of this article.
Limitation of liability
To the fullest extent allowed by law, we are not liable for any indirect, incidental, or consequential damages, or for any loss of data or profits, arising from your use of the Service. Because the software is open source, you can always self-host to keep full control of your data.
Termination
You can stop using the Service at any time. We may suspend or end access where these terms are breached.
