Terms of Service

Athanor is free to use. We grant you a personal, non-exclusive, non-transferable license to use it for any lawful purpose, including study, teaching, research and commercial work. You may not copy, resell or redistribute the app itself, or reverse engineer it except where the law allows you to.

We work on Athanor continuously. Features may change, move or be withdrawn, and the desktop app updates itself. If we ever charge for a feature, we will say so before you use it, and nothing you made with a free feature will be held back.

You own the documents, drawings, structures, problem sets and other content you make in Athanor. We claim no rights to them. You give us only the permission we need to run the features you use with them: to store, sync, back up and display your content to you and to the people you share it with.

Athanor saves in an open file format (.athanor) holding standard chemistry formats, so your work can be opened without our app. Keep your own copies of anything important. Autosave and backups reduce the risk of losing work but cannot remove it.

When you upload something to the community library, it becomes public, and you give every Athanor user permission to view, use and adapt it in their own work, and us permission to host and display it. You can remove your uploads; copies others already made remain theirs to use.

Only upload or share what you have the right to share, including files you attach to comments. Do not post anything unlawful, anything that infringes someone else's rights, other people's personal information, or anything meant to harass. We may remove content and suspend accounts that break these rules.

Anyone signed in can report a community upload or comment. An upload reported by three different people is hidden until a moderator looks at it, and a moderator may restore it or remove it. Reporting something in bad faith is itself against these rules.

Athanor checks structures and offers predictions: names, properties, reaction outcomes, retrosynthetic routes, spectra, AI answers and similar. These are computed or generated estimates. They can be wrong, and Athanor labels them as predictions and shows where values come from.

Do not rely on Athanor as your only check for anything where a mistake could cause harm, including laboratory work, safety assessments, dosing, regulatory filings, or published results. Verify against primary sources and use your professional judgment. Hazard information in Athanor, such as GHS labels, is a reference and does not replace a supplier's safety data sheet or your institution's safety procedures.

You may not use Athanor to:

• Plan, design or obtain routes to chemical weapons, their precursors, or other agents controlled under the Chemical Weapons Convention or Australia Group lists.
• Produce controlled substances or explosives unlawfully, or help anyone else do so.
• Get around the safety screening built into Athanor, including by splitting, disguising or rephrasing requests.
• Break export-control, sanctions or other laws that apply to you.

Athanor screens structures and routes and refuses some of them. If you believe a refusal is wrong, you can ask us to review it from within the app. We may suspend accounts used against these rules and report them where the law requires.

The assistant runs on the AI provider you choose, with an API key you provide. Your use of that provider is governed by your agreement with it, and you are responsible for the key, its charges, and following the provider's usage policies. Answers come from the provider's model; the rules in "Predictions are not facts" apply to them fully.

Teachers may use Athanor to make, hand out and check problem sets. If you use it with students, you are responsible for following your school's policies and the laws on students' information. An arbastro account requires the account holder to be at least 13. If you set up an organization for a school or company, you are responsible for who you make an admin and for the email domains you say are yours. Student pricing is for people enrolled at a school; we may ask a verified student to verify again, and withdraw the price from an account that is not one.

Athanor includes and links to material from others, such as PubChem data, protein structures from RCSB and AlphaFold, and illustrations from NIH BioArt. Each keeps its own license, which Athanor shows with it; follow the license when you use the material, including giving credit where it asks for credit.

If you install Athanor from the Microsoft Store, Microsoft's terms for the Store also apply to how it is delivered to you. Microsoft is not responsible for Athanor or for supporting it; we are.

Athanor is provided "as is" and "as available", without warranties of any kind, to the fullest extent the law allows. We do not promise it will be error-free, uninterrupted, or that its predictions are accurate. The limits on arbastro's liability in the arbastro Terms of Service apply to Athanor. Nothing in these terms limits rights you have as a consumer that the law does not let us limit.

You can stop using Athanor at any time, and you can delete your account as the arbastro terms describe. We may suspend or end your access if you break these terms. If we ever discontinue Athanor, we will give reasonable notice so you can export your work; your files on your own device remain readable either way.

We may update these terms. The date at the top shows the latest version, and we will tell you in the app about significant changes before they take effect. Continuing to use Athanor after that means you accept them. Questions: [email protected], arbastro Inc.
