Effective Date: March 8, 2026 | Version 5.0
These Terms of Service (“Terms”) govern your access to and use of the Arithym computation service, application programming interfaces (APIs), MCP server software, documentation, and related services (collectively, the “Service”) provided by Geometric Data Systems, Inc., a Delaware corporation registered in Minnesota (“Arithym,” “Company,” “we,” “us,” or “our”).
By creating an account, accessing, or using the Service, you agree to be bound by these Terms. If you are using the Service on behalf of an organization, you represent and warrant that you have authority to bind that organization to these Terms. If you do not agree to these Terms, do not use the Service.
“Service” means the Arithym computation platform, including the REST API, MCP server, SDK libraries, documentation, and any updates or modifications thereto.
“User,” “you,” or “your” means any individual or entity that accesses or uses the Service.
“API Key” means the unique authentication credential issued to you upon registration.
“Content” means the inputs you submit to the Service and the outputs the Service returns to you.
“Subscription Tier” means the level of service associated with your account (Explorer, Pro, or Engineer), each with distinct usage limits.
“Computational Output” means any mathematical result, value, tolerance bound, precision indicator, or metadata returned by the Service.
To use the Service, you must create an account by providing a valid email address and explicitly accepting these Terms. By completing registration, you acknowledge that:
Your acceptance of these Terms is recorded with a timestamp at the time of registration. You may not create multiple accounts for the purpose of circumventing usage limits or other restrictions.
API Key Security. Your API Key is shown once upon email verification and cannot be retrieved thereafter. You are solely responsible for storing your API Key securely. Arithym is not liable for any unauthorized access to your account resulting from your failure to safeguard your API Key. Arithym will never ask you for your API Key via email, phone, or any other channel.
Arithym provides a computation service designed to deliver mathematical results to software applications and AI agents via the Model Context Protocol (MCP) and REST API. The Service accepts numerical and mathematical inputs and returns computed results along with metadata including precision indicators, tolerance bounds, and structural information.
The specific methods, algorithms, processes, architectures, and techniques used by the Service to produce results constitute proprietary trade secrets of Arithym and are not disclosed to Users.
Arithym reserves the right to modify, improve, or change the internal methods and processes of the Service at any time without notice, provided that the external API interface and documented behavior remain materially consistent.
The Service is offered across the following tiers:
Arithym reserves the right to modify pricing and usage limits with 30 days’ notice to existing subscribers. Changes take effect at the start of the next billing cycle. Fees are billed monthly in advance through our payment processor (Stripe, Inc.). All fees are non-refundable except as required by applicable law. Arithym is not responsible for any fees, charges, or taxes imposed by your payment method provider.
You agree to use the Service only for lawful purposes and in compliance with these Terms. You agree not to:
All right, title, and interest in and to the Service — including but not limited to all software, algorithms, methods, processes, architectures, designs, data structures, documentation, trademarks, trade names, and trade secrets — are and shall remain the exclusive property of Arithym. These Terms do not grant you any right, title, or interest in the Service except for the limited right to use the Service in accordance with these Terms.

The internal workings of the Service — including but not limited to computational methods, data structures, optimization techniques, precision mechanisms, processing pipelines, and architectural decisions — are confidential and proprietary trade secrets of Arithym. You agree not to:
This confidentiality obligation survives termination of your account and these Terms.
IMPORTANT: READ THIS SECTION CAREFULLY.
