Terms of Service

Effective Date: March 1, 2026 · Last Updated: May 21, 2026

These Terms of Service (“Terms”) constitute a legally binding agreement between you (“Customer,” “you,” or “your”) and Detailed In Design, LLC, an Illinois Limited Liability Company (“Company,” “we,” “us,” or “our”), governing your access to and use of the Dataset Reality Check hosted application and related services.

1. Acceptance of Terms

By accessing or using Dataset Reality Check, you acknowledge that you have read, understood, and agree to be bound by these Terms. You represent that you are at least 18 years of age and have the legal capacity to enter into this agreement. If you are accepting these Terms on behalf of an organization, you represent that you have the authority to bind that organization.

2. Service Description

Dataset Reality Check is a hosted application for pre-model epistemic dataset analysis. The application enables you to:

Analyze dataset quality before model training
Detect drift, regime shifts, and distributional anomalies
Assess feature fragility and identify unstable predictors
Identify assumption violations that undermine model reliability
Generate analysis reports and diagnostic summaries

The application supports CSV, TSV, and Parquet file formats with a maximum file size of 500 MB per file.

Hosted Launch Scope: The June 1 self-serve service processes non-regulated datasets uploaded by authorized users. Private, offline, desktop, and air-gapped deployments require a separate enterprise agreement.

3. Account Registration

You must complete the DID checkout and license-agent account flow to obtain a license key. You agree to provide accurate and complete registration information. You are responsible for maintaining the confidentiality of your account credentials and license key. You must notify us immediately at privacy@detailedindesign.com of any unauthorized use of your account.

4. License Grant

Subject to your compliance with these Terms and payment of applicable fees, we grant you a limited, non-exclusive, non-transferable, revocable license to:

Access the hosted Dataset Reality Check service under the seats and usage limits permitted by your subscription tier
Use the application for its intended purpose of non-regulated dataset analysis
Generate and retain analysis reports for your own use

This license does not include the right to:

Sublicense, resell, or redistribute the application or any component thereof
Reverse engineer, decompile, or disassemble the application
Remove or alter any proprietary notices, labels, or marks
Use the application for competitive analysis or benchmarking without prior written consent
Modify or create derivative works based on the application

5. License Verification and Private Deployments

5.1 Online Verification

Hosted subscriptions are verified through the Detailed In Design account, billing, and license systems. Private deployments may perform a periodic license heartbeat. Hosted job processing is separate from license verification.

5.2 Offline / Air-Gap Activation

For environments that require no network connectivity, offline activation is scoped as custom enterprise work:

Deployment, support, updates, and retention must be agreed in writing
Offline keys and renewal terms are defined in the enterprise agreement
Air-gap deployments are not part of the self-serve hosted SaaS launch
Network behavior is governed by the private deployment configuration

6. Subscription Tiers and Pricing

Dataset Reality Check is available in the following subscription tiers:

Starter - $199/month: Core hosted analysis workflows and email support.
Professional - $399/month: Advanced hosted analysis, API access, and priority support.
Enterprise - $1,199/month: Expanded hosted usage, SSO-ready planning, custom rules, and enterprise deployment scoping.

All pricing is subject to change with 30 days’ written notice. Price changes take effect at the start of the next billing cycle.

7. Billing and Payment

Payment is processed through Detailed In Design checkout and Stripe. Subscription fees are billed monthly or annually in advance and are non-refundable except where required by law or explicitly stated in a written order form.

Late payment results in license suspension after 15 days’ notice. Outstanding balances accrue interest at 1.5% per month or the maximum rate permitted by law, whichever is lower. Suspended licenses prevent hosted access unless an enterprise agreement provides a different remedy.

8. Data Ownership

Your data is yours. You retain all right, title, and interest in your datasets, analysis results, and any outputs generated by the application. We claim no ownership, license, or rights of any kind over your data.

For hosted SaaS, datasets you upload are processed for the requested analysis job. You must not upload PHI, payment card data, classified data, or other regulated datasets unless a separate enterprise agreement authorizes that use.

9. File Size and Format Limitations

The application supports the following file formats and size limits:

Supported Formats: CSV (comma-separated values), TSV (tab-separated values), Parquet (Apache Parquet)
Maximum File Size: 500 MB per file
Encoding: UTF-8 encoding is required for CSV and TSV files

Files exceeding the 500 MB limit will be rejected at load time. The Company is not responsible for performance degradation when processing files near the maximum size limit on hardware with insufficient resources.

10. Intellectual Property

The Company retains all right, title, and interest in Dataset Reality Check, including all software, algorithms, analysis methods, user interface designs, and documentation. Nothing in these Terms transfers any intellectual property rights to you except the limited license granted in Section 4.

11. Acceptable Use

You agree not to:

Use the application for any purpose that violates applicable laws
Attempt to circumvent license restrictions, activation mechanisms, or file size limits
Share your license key with unauthorized users or organizations
Use the application to process data for which you lack lawful authorization
Transmit malware through the license verification channel
Interfere with the application’s operation or security mechanisms

12. Privacy

The Company is not responsible for decisions made based on analysis results.

14. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE COMPANY’S TOTAL LIABILITY SHALL NOT EXCEED THE AMOUNTS PAID BY CUSTOMER IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO LIABILITY. IN NO EVENT SHALL THE COMPANY BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL, INDIRECT, SPECIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOST PROFITS, LOST DATA, OR COSTS OF PROCUREMENT OF SUBSTITUTE SERVICES.

You are responsible for keeping source copies of uploaded datasets and for ensuring the data you upload is authorized for hosted processing.

16. Updates and Maintenance

The Company may release updates to the hosted application to fix bugs, improve performance, or add features. Private, offline, and air-gapped installations require a separate maintenance and update process.

The Company reserves the right to discontinue the application with 90 days’ written notice. In the event of discontinuation, customers will receive a pro-rated refund for any prepaid subscription fees.

17. Termination

By Customer: You may cancel your subscription at any time through the customer portal. Cancellation takes effect at the end of the current billing cycle. Hosted access will cease after your subscription expires.
By Company for Breach: We may terminate your license for material breach of these Terms with 30 days’ written notice and opportunity to cure.
By Company for Non-Payment: We may suspend and terminate your license after 15 days’ written notice of non-payment.

18. Modifications to Terms
