1. Who provides this service

ERDism is operated by Cutaway Works, based in the Republic of Korea. In these terms, "we" and "us" mean Cutaway Works, and "you" means the person using ERDism.

You can reach us at [email protected].

2. Accepting these terms

These terms cover ERDism at erdism.com: the website, the application, and the public documentation.

By creating an account or using the service, you accept these terms and confirm that you have read our Privacy policy. The Privacy policy explains how we handle personal data; it is not something you are asked to agree to. There is no separate box to tick. Every screen where an account can be created — signing up with an email address, or continuing with Google or GitHub — says so directly under the button, together with the minimum age (section 4).

If you use ERDism on behalf of a company or another organisation, you confirm that you have the authority to accept these terms for it.

3. The service

ERDism is where a team keeps its database schema. Everyone who works with the database reads the same live schema, every change to it is recorded, and changes are reviewed before they are published.

ERDism is in beta. Features may change, move, or be withdrawn while we learn what works, and we do not promise any level of availability. Because of that, you can always take your schema with you: any project can be exported as SQL.

4. Accounts

You can open an account with an email address and a password, or by continuing with Google or GitHub. A password must be at least 8 characters and at most 255. There are no other composition rules.

An account is identified by its email address, and there is one account per address. When you sign up with a password we email you a link to confirm the address. Until you confirm it, you can only confirm it, have the link sent again, correct the address, sign out or close the account — you cannot use the rest of ERDism. An account that is not confirmed within seven days is deleted. If someone signs up with an address whose account has not been confirmed, the new sign-up replaces it: whoever confirms the address first owns it. If you later continue with Google or GitHub using an address that already has an account, that provider is attached to the existing account rather than creating a second one.

You must be at least 16 years old to open an account.

You are responsible for your password and for the Google or GitHub accounts that can sign in as you. Choose a password you do not use anywhere else, and do not let anyone else use your account. If there are too many failed attempts to sign in to an account, or from one network address, in a short time, further attempts are refused for about fifteen minutes. The account is not locked: you can try again once that time has passed.

5. Acceptable use

You may not use ERDism to:

  • store or share content that is unlawful, or that infringes someone else's rights;
  • try to get into accounts, workspaces or projects you have not been given access to, or into the systems that run the service;
  • put an unreasonable load on the service, for example with automated requests;
  • use another person's account, or let someone else use yours;
  • resell the service, or access to it, without our written agreement.

If you do, we may remove the content concerned or suspend your account, as described in section 10.

Reporting content

If content shown through ERDism — for example a project opened through a public link — invades your privacy, defames you or otherwise infringes your rights, you can ask us to remove it. Write to [email protected] with the address of the content, what in it infringes your rights, and why.

  • When we receive a request, we remove the content without delay or, if it is unclear whether it infringes your rights or the person who posted it disputes the request, block access to it for up to 30 days while the matter is settled.
  • We tell both sides. We tell you what we did, and we tell the workspace that holds the content what was requested and what we did. Its owner can tell us why the content should stay.
  • After a temporary block, if within the 30 days the matter is not settled in favour of keeping the content, we remove it.

6. Your content

The schemas, diagrams, SQL and documentation that you upload or create remain yours — or, if you work in an organisation's workspace, that organisation's.

You give us permission to store, process and display that content as far as we need to in order to run the service for you and for the people you share it with.

You also allow us to learn from it in one limited way. We may derive knowledge from it that does not identify you, your workspace or your project — totals, and patterns or shapes in which every name has been replaced by a placeholder — and use that knowledge to improve ERDism, including to train machine-learning models. We never train models on your schemas, SQL or documentation themselves. Section 9 of the Privacy policy sets out what we derive and the rules it follows, as well as what we keep, what we delete, and what becomes public only when you choose.

We do not use your content for advertising, and we do not sell it or anything derived from it.

7. Workspaces and members

A workspace holds projects, and a project holds diagrams, SQL and documentation. A workspace stands for one organisation. Every account gets a personal workspace when it is created, and you can create more.

The owner of a workspace has the highest authority in it and can open every project in it, whatever the project roles say. Members are invited to the workspace and carry a role there; an invitation can be accepted for seven days. The owner can hand the workspace to another member, and the previous owner then stays on as a member.

Content belongs to the workspace, not to the member who typed it. When a member leaves or is removed, they lose access straight away, but what they created stays, and the history keeps showing them as the person who made each change.

When you delete a project or a workspace it goes to the trash. Anything in the trash is permanently deleted seven days after it was put there. For the first three days it can be restored but cannot be permanently deleted by hand, so that a mistake can still be undone.

If you own a workspace that has other members, you cannot close your account until you have handed that workspace to another member or deleted it, so a team never loses its work because its owner left. A workspace you own with no other members is closed together with your account.

8. Fees

ERDism is free during the beta. No payment is taken, and no payment details are asked for or stored.

During the beta there is no limit on how many members of a workspace can have editing rights, apart from a technical ceiling of 30 people with editing rights per workspace. If you need more, contact us.

Paid plans will come after the beta. A plan belongs to a workspace, and the workspace owner is responsible for paying for it. Every plan includes every feature. Plans differ only in their size: how many people can edit in the workspace, and how many live databases ERDism keeps watch on for it. People who only view are free on every plan. The pricing page sets out what each plan includes.

When the beta ends, we will tell workspace owners at least 30 days in advance, by email and inside the service. Nobody is removed from a workspace when it ends, and nothing anyone made is lost. In each workspace, everyone who had editing rights before that announcement and edited during the beta keeps them. Other people with editing rights become viewers: they stay members, and their history stays. The workspace's free plan then allows as many people with editing rights as kept them this way, or three if that is more.

After the beta, when a workspace already has as many people with editing rights as its plan allows, giving them to one more person needs a paid plan. On the free plan that number is three, or the number the workspace kept when the beta ended. People who already have editing rights keep them; when one of them leaves, their place is not filled again without a paid plan.

We will tell workspace owners at least 30 days before any of this changes, by email and inside the service. Payments may be handled by a reseller (a merchant of record). When that happens the reseller is the seller, and its purchase terms apply alongside these. Refunds are covered by our Refund policy.

9. Availability and changes to the service

We work to keep ERDism running, but during the beta we make no promise about uptime and the service may be interrupted for maintenance or by faults. We may add, change or remove features.

10. Suspension and ending the agreement

We may suspend or close an account, or remove content, if it breaks these terms, if the law requires us to, or if it puts the security of the service or of other users at risk. We will tell you first and give you a chance to respond, unless the situation is urgent or the law does not allow us to.

You can close your account from your account page at any time. You confirm it with your password, or — if your account signs in only with Google or GitHub — by signing in with that provider again. Closing an account hides the account, your profile, your memberships, the invitations you sent or received, and the workspaces and projects you own — which, as section 7 says, can only be workspaces with no other members. You are signed out everywhere.

For thirty days after you close it, you can reopen the account — with your email address and password, or by continuing with the same Google or GitHub account — and everything that was closed with it comes back. During those thirty days its email address cannot be used to open a new account. After thirty days the account is erased as section 8 of the Privacy policy describes, and can no longer be reopened. If you want it erased sooner, ask us as described in section 10 of the Privacy policy.

11. Warranties and liability

ERDism is provided "as is" and "as available". As far as the law allows, we make no promises about the service beyond those written in these terms.

As far as the law allows, we are not liable for indirect or consequential losses, such as lost profits, lost revenue or lost business opportunities. Our total liability to you for any claim is limited to the amount you paid us for the service in the 12 months before the claim arose. If you paid nothing, it is limited to the smallest amount the applicable law permits.

Nothing in these terms limits a liability, or takes away a right, that consumer protection law does not allow to be limited or taken away.

12. Governing law and disputes

These terms are governed by the laws of the Republic of Korea. Any dispute about them is heard by the Seoul Central District Court.

If you use ERDism as a consumer, you keep the protection of the mandatory laws of the country where you live.

13. Changes to these terms

When we make an important change to these terms, we will tell you at least 30 days before it takes effect, by email and inside the service. If you keep using ERDism after a change takes effect, you accept the new terms. If you do not accept them, you can close your account before then.

The date at the top of this page shows when these terms were last changed.
