Terms of Use

By creating an account on 1D2A, or by otherwise accessing or using the service, you agree to be bound by these Terms of Use. If you are using 1D2A on behalf of an organization, you confirm that you have the authority to accept these terms on its behalf.

If you do not agree with any part of these terms, please do not use 1D2A.

1D2A is a tool for preparing, making, and preserving decisions. It lets you build the rationale behind a decision as a structured log of interlinked nodes — options, assumptions, evidence, risks, arguments, and commitments — and to keep an immutable record of how the reasoning developed.

1D2A is a personal project by Ivan Jureta. It is not affiliated with, endorsed by, or operated on behalf of any organization, and it is offered free of charge until further notice.

You may sign in with a supported identity provider, such as Google, or with an email address. You are responsible for keeping access to your account secure and for all activity that takes place under it.

You must provide accurate information, be an adult in the country you are using 1D2A.com in, and not share your account in a way that misrepresents who is using it. Notify the contact below promptly if you believe your account has been accessed without authorization.

You retain ownership of the decision logs, nodes, attachments, and other content you create on 1D2A. These terms do not transfer any ownership of your content to 1D2A.

You grant 1D2A only the limited rights needed to host, store, back up, display, and operate the service on your behalf — for example, rendering your logs in your browser and preserving their history. You are responsible for having the rights to any content you add, and for not including material you are not permitted to store or share.

You may choose to publish a decision log or template so that it is readable by others, including signed-out visitors browsing the public library. Publishing is an explicit, deliberate action that you make; logs are private to you and the people you invite unless you publish them.

Only publish content you have the right to make public, and avoid including confidential information or personal data about others. Because 1D2A is built around an immutable history, published snapshots are designed to persist and may have been viewed or referenced by others before you change them.

You agree not to use 1D2A to break the law, infringe the rights of others, or store or share content that is unlawful, harmful, or that you have no right to handle. You also agree not to attempt to disrupt or compromise the service, to access accounts or logs that are not yours, or to extract data from the service at scale through automated means.

1D2A may suspend or limit access where use threatens the integrity, security, or lawful operation of the service.

Some features use automated and AI-based assistance to assess reasoning for gaps, surface overlooked risks, or suggest additional options. This output can be incomplete, inaccurate, or unsuitable for your situation.

1D2A uses OpenAI models via API. We provide AI services only if you provide us with an API key from OpenAI. Otherwise, you cannot use AI features on 1D2A. This ensures that we are not responsible for whether you have allowed OpenAI to use your data to train their models, and it makes you responsible for covering the costs of using OpenAI models.

AI assistance is intended to prompt your own judgment, not to replace it. You remain solely responsible for the decisions you prepare, record, and make using 1D2A.

How 1D2A handles personal data is described in the Privacy Policy, which forms part of these terms. By using 1D2A you also agree to the practices described there.

1D2A is offered free until further notice. It is provided on a best-effort basis, without any guarantee of uninterrupted or error-free availability.

Features may be added, changed, suspended, or removed over time. Where a change is material and notice is practical, reasonable advance notice will be given. If the service is ever discontinued, reasonable steps will be taken to let you export your logs first.

The 1D2A name, design, interface, and underlying software are the property of their author and are protected by applicable law. These terms grant you a personal, non-exclusive, non-transferable right to use the service — they do not grant you any rights in the 1D2A brand, design, or software beyond that use.

1D2A is provided "as is" and "as available", without warranties of any kind, whether express or implied, including fitness for a particular purpose and non-infringement, to the maximum extent permitted by law. 1D2A does not warrant that the service will meet your requirements or that the reasoning it helps you record will lead to any particular outcome.

To the maximum extent permitted by law, and given that 1D2A is provided free of charge, 1D2A and its author will not be liable for any indirect, incidental, special, or consequential damages, or for any loss of data, profits, or decisions arising from your use of or inability to use the service.

Nothing in these terms excludes any liability that cannot lawfully be excluded.

You may stop using 1D2A at any time and may request deletion of your account and content. 1D2A may suspend or terminate access where these terms are breached, or where required to protect the service or comply with the law. Provisions that by their nature should survive termination — such as ownership, disclaimers, and limitation of liability — will continue to apply.

These terms may be updated from time to time. When changes are material, the updated version and its effective date will be posted here, and reasonable notice will be given where practical. Your continued use of 1D2A after a change takes effect means you accept the revised terms.

These terms are governed by the laws of Canada, the Province of British Columbia, without regard to conflict-of-law principles. Where a dispute cannot be resolved informally, it will be subject to the competent courts of that jurisdiction, except where mandatory local consumer law grants you other rights.

Questions, requests, or concerns about these terms can be sent to ivan@ivanjureta.com. Because 1D2A is a personal project, correspondence is handled directly by its author.
