Terms of Service

These terms are an agreement between you and [Legal entity name], company number [Company number], registered at [Registered address]. In these terms that company is called Nitsor. They cover nitsor.com, your Nitsor account and the hosted service.

About these terms

You accept these terms when you create an account or use the hosted service. If you act for an organisation, you accept them on its behalf and confirm that you have authority to do so. In that case, "you" means the organisation. If you do not have that authority, do not create the account.

The Privacy Policy explains how Nitsor handles personal data, and the Cookie Policy lists the cookies and browser storage the sites use. Neither one changes what these terms allow or what you pay.

Which terms apply to your plan

Community is free, and you run it on infrastructure you provide. The source-available licence distributed with the software governs how you may use that software. These terms cover nitsor.com and any Nitsor account you create. They do not widen the licence, and Nitsor does not operate your installation.

Team is hosted by Nitsor and governed by these terms. At paid launch, the subscription is paid upfront, monthly or yearly, and includes 250 model-assisted volumes per monthly billing cycle. Extra volumes cost $0.25 each and settle after that cycle. The pricing page states the launch prices. These are launch prices. Paid checkout and usage charging are not active.

Enterprise is arranged with the Nitsor sales team and billed separately under a signed order form or agreement. Where that document conflicts with these terms, the signed document wins. These terms cover anything it does not address. Existing negotiated commitments, rollover and overages remain governed by that agreement; the Team rate does not change Enterprise contracts. Hosted model runs are available on Team and Enterprise at paid launch, within the supported scope.

Accounts

Give accurate account and billing details and keep them current. You are responsible for the people you invite, for the roles you give them and for what they do in your account. Remove access when someone no longer needs it.

Keep sign-in details private. If you learn of unauthorised access to your account, tell Nitsor at [legal contact email] as soon as you can.

Team payment and Enterprise billing

Creating a Team account does not start a paid subscription. At paid launch, you accept the plan, included allowance and overage rate and complete checkout before the subscription starts.

Monthly Team pays $649 upfront per workspace per month. Yearly Team pays $6,228 upfront per workspace per year; $519 per month is only an equivalent, not a monthly debit. The subscription renews on its selected monthly or yearly cadence until cancellation. The subscription is paid upfront. Extra usage is settled after each monthly billing cycle. A cycle follows your billing dates and can start partway through a calendar month. Included volumes reset at the start of each monthly billing period on both Team plans; unused volumes do not carry over. The yearly plan does not pool the allowance for the year.

One model-assisted volume is one completed scan/model result under the existing scan identity rules, with every object the model finds included. Within one billing period, the first successful run of a model version on a scan counts one volume. Later runs of the same model version on the same scan in that period are free. A new billing period, a new model version or a different scan counts again. A failed run never counts. See the scan identity rules for each format.

Team runs follow these controls. Before every run you see its quote: included volumes, any extra volumes at $0.25 each, and the most the run can be charged. You confirm before it starts; the charge cannot exceed that quote. Each Team workspace has a default usage budget of $1,000 per monthly billing period on top of the subscription, before tax. A run that would take usage past the budget waits instead of starting. A repeat run, which is free, can start even when the budget is used up.

A workload outside the supported models and scan sizes, including an exceptionally expensive run, needs a separate fixed quote agreed before it runs, with no surprise runtime charge.

New paid signups accept these prices at signup, without an automatic extra 30-day free-usage period. We honour free-usage or advance-notice commitments actually made to existing accounts. Development, test and free-pilot usage is never billed retroactively.

At paid launch, you can cancel from the billing portal. Cancellation takes effect at the end of the current billing period, and partial periods are not refunded unless the law requires it. Charges already incurred remain due. Fees exclude taxes, which you pay except for taxes on Nitsor's income.

Nitsor will give you at least 30 days' notice before changing the Team fee. The new fee applies from your first renewal after the notice period ends, so you can cancel before it does. To dispute a charge, write to [legal contact email] and say which charge and why.

Enterprise charges, including any hosted model compute, and invoicing and payment dates are set in the signed order form.

Fair use

Team is unlimited for people, labels and reviews under fair use. Fair use also covers Nitsor-managed storage, including uploaded scans, label records, history and dataset versions, and the volume of API traffic, including from agents and scripts. Existing scans referenced in customer storage remain in that storage.

Fair use is not a meter, and Nitsor does not bill for it. If a workspace uses far more than a typical team, we talk to its owner and agree a plan that fits. We give notice before we change this policy.

Your data

You own your scans, labels and the records your work creates. You give Nitsor permission to host, process and display them only as needed to provide the service you use, including through the providers listed in the Privacy Policy. That permission ends when the agreement ends, apart from the deletion steps described below.

Existing scans registered by reference remain in customer storage. Uploads can go to a write-enabled customer bucket or a Nitsor-managed bucket, or Nitsor can manage all storage. Hosted uploads use Nitsor storage by default; the owner can switch it off. Nitsor-managed storage falls under the fair-use policy. Managed uploads are retained until the owner deletes them. The browser reads viewed slices through signed links that expire within 900 seconds. Customer connections start read-only; saving masks, stored previews, uploads and model outputs requires write access. On read-only connections, Nitsor keeps source metadata, point, box and class labels, reviews, audit events and dataset version manifests, never scan pixels or derived files. Bulk voxels never pass through the control plane. Preview and hosted model jobs process temporary inputs on Modal for the length of the job. Nitsor never deletes source scans in customer storage.

Nitsor does not use your data to train models.

You need the rights and permissions to register and process everything you put into Nitsor. You also control your storage: keep the credentials you give Nitsor limited to what the connection needs, and replace them if you think they are exposed.

Clinical images and health data

You may register clinical images only when you have the right to use them for the work you ask Nitsor to do. De-identifying images and their metadata where the law requires it, and giving any notices and getting any permissions, is your responsibility.

Nitsor makes no HIPAA claim. Do not put protected health information into hosted Nitsor unless Nitsor has agreed to it in writing. A subscription, or the fact that a scan can be registered, is not that agreement.

Acceptable use and security

Use Nitsor lawfully and within your plan and licence. Do not access another organisation's data, interfere with the service or its providers, upload malicious code, get around access or payment controls, resell access, or use the service to infringe anyone's rights.

Do not test for vulnerabilities without written permission. If you find a security problem, report it to [legal contact email] without accessing or sharing data that belongs to someone else.

Model output

Model proposals are suggestions for a person to review. They can be incomplete or wrong. Check them against the source scan before you rely on them. Your quality authority makes the call on what to accept and how it is used, and you remain responsible for decisions made with scans, labels and model output.

Confidentiality

Each party keeps the other's confidential information private and uses it only for this agreement. Your data counts as confidential information. Each party may share the other's confidential information only with staff and providers who need it for that purpose and are bound by confidentiality duties, and is responsible for what they do with it.

These duties do not cover information that is public through no fault of the recipient, that the recipient already had lawfully or developed on its own, or that the law requires it to disclose. In the last case the recipient will tell the other party first where the law allows. The duties continue after the agreement ends.

Nitsor's software and your feedback

Nitsor and its licensors keep all rights in the service, the software and this website. You receive only the rights these terms, a signed agreement or the Community licence give you.

If you send suggestions, Nitsor may use them to improve its products without paying you or naming you. This does not cover your data or confidential information included with them.

Suspension, cancellation and termination

Nitsor may suspend access if you seriously breach these terms, do not pay charges that are due, or your use creates a security or legal risk. Nitsor will limit the suspension to what is needed and tell you why, unless the law or the risk prevents it.

Either party may end the agreement if the other seriously breaches it and does not fix the breach within 30 days of written notice, or at once if the breach cannot be fixed. You can close your account at any time by writing to [privacy contact email]. Team cancellation follows the billing terms above.

While your account is open, your labels and their history stay available in the product, and you can export them until the account closes. Accounts are closed on request, as the Privacy Policy describes: Nitsor deletes or anonymises the account and its workspace records by hand. Before closing the account, export any scans in Nitsor-managed storage that you want to keep and request deletion of managed uploads when you ask for account closure. The account and workspace-record deletion period does not set a deletion deadline for managed scan files. Nitsor never deletes source scans in customer storage.

Disclaimers and liability

As far as the law allows, the website and the hosted service are provided as they are, without implied warranties of quality, fitness for a particular purpose or non-infringement. Nitsor does not promise that the service will be uninterrupted or free of errors.

Neither party is liable for indirect or consequential loss, or for lost profits, revenue or goodwill. The most Nitsor will pay for all claims under this agreement together is what you paid Nitsor during the 12 months before the first claim arose. If you paid nothing in that time, for example on Community, Nitsor's liability is limited as far as the law allows.

Some liability cannot be limited by contract, such as liability for fraud or for death or personal injury caused by negligence. These terms do not try to limit it.

If someone claims that data you put into Nitsor infringes their intellectual property, you will defend Nitsor against that claim and pay any damages finally awarded. The party being defended must tell the other promptly and help with the defence.

Changes to these terms

Nitsor will tell account owners by email or in the product at least 30 days before a material change takes effect, and will name the change and its date. If you do not accept it, cancel before that date. Using the service after that date means you accept the change. A signed Enterprise agreement may set its own change process.

Governing law and contact

These terms, and any dispute about them, are governed by the laws of the State of Delaware, United States, with the state and federal courts in Delaware deciding any dispute, except where mandatory law gives you rights that these terms cannot remove.

Neither party may transfer the agreement without the other's written consent. If part of these terms cannot be enforced, the rest still applies. A delay in using a right does not give it up.
