Terms of Service

Effective Date: March 1, 2026 · Last Updated: March 4, 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 desktop application and related services.

1. Acceptance of Terms

By downloading, installing, 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 desktop 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.

Desktop-Only Architecture: Dataset Reality Check is a locally installed application. All dataset processing occurs on your machine. No dataset contents are transmitted to our servers. The application communicates with our servers only for license verification (see Section 5).

3. Account Registration

You must create an account through our customer portal at portal.detailedindesign.com 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:

Download and install the Dataset Reality Check application on the number of devices permitted by your subscription tier
Use the application for its intended purpose of 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 Offline Activation

5.1 Online Verification

By default, the application performs a periodic license heartbeat to verify your subscription status. This heartbeat transmits only your license key, application version, operating system type, and a timestamp. No dataset information or usage data is transmitted.

5.2 Offline / Air-Gap Activation

For environments that require no network connectivity, we provide offline activation:

Request an offline activation key through the customer portal
Offline keys are valid for the duration of your billing cycle and must be renewed at each cycle
Air-gap deployments are supported on all subscription tiers
When operating with an offline key, the application makes zero network connections of any kind

6. Subscription Tiers and Pricing

Dataset Reality Check is available in the following subscription tiers:

Starter - $199/month: Core analysis workflows, single-device license, community support.
Professional - $399/month: Advanced analysis, multi-device license, priority support, offline activation.
Enterprise - $1,199/month: Full feature set, unlimited devices, dedicated support, air-gap deployment, custom integrations, volume licensing.

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 Stripe. Subscription fees are billed monthly in advance and are non-refundable except within a 14-day initial evaluation period from the date of first purchase. If you cancel within the 14-day evaluation period, you will receive a full refund.

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 application launch; local data and configurations remain intact on your device.

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.

Because the application processes data entirely on your machine, your datasets never enter our possession. We have no ability to access, view, copy, or control your data at any point.

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

Your use of Dataset Reality Check is also governed by our Privacy Policy, which describes how we handle the limited information we collect (license heartbeat, account data, and payment information). Your datasets are never collected, transmitted, or accessed by us.

13. Warranty Disclaimer

THE APPLICATION IS PROVIDED “AS IS” AND “AS AVAILABLE.” TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE COMPANY DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT.

Without limiting the foregoing:

Analysis results are provided as decision-support information, not as definitive conclusions about dataset quality.
The Company does not guarantee that analysis results will be error-free or that all dataset issues will be detected.
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.

Because your datasets are processed locally and never leave your machine, the Company bears no liability for data loss, data corruption, or unauthorized access to your datasets.

15. Indemnification

Customer Indemnification: You agree to indemnify and hold harmless the Company from claims arising from your use of the application, data processed in violation of applicable law, and decisions made based on analysis results.

Company Indemnification: The Company will indemnify you against third-party claims that the application infringes a valid patent or copyright.

16. Updates and Maintenance

The Company may release updates to the application to fix bugs, improve performance, or add features. For online installations, updates may be delivered automatically with a minimum 48-hour notice for non-critical updates. Offline / air-gap installations require manual update via downloadable packages from the customer portal.

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. The application will cease to function after your license 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.

Upon termination, your license key is deactivated. All local data, configurations, and analysis results remain on your device and under your control. We do not have the ability to delete data from your machine.

18. Modifications to Terms

The Company may modify these Terms with 30 days’ written notice of material changes via email to your account address. Continued use after the effective date constitutes acceptance. Non-material changes may be made by updating the “Last Updated” date.

19. Governing Law and Jurisdiction

These Terms are governed by the laws of the State of Illinois, without regard to conflict-of-law principles. Any disputes shall be subject to the exclusive jurisdiction of the state and federal courts located in Cook County, Illinois.

20. Dispute Resolution

Negotiation: The parties shall first attempt to resolve disputes through good-faith negotiation for 30 days.
Mediation: If unresolved, disputes shall be submitted to mediation in Cook County, Illinois.
Arbitration: If unresolved within 60 days, disputes shall be submitted to binding arbitration in Cook County, Illinois before the American Arbitration Association (AAA) under its Commercial Arbitration Rules.

Class Action Waiver: You agree to resolve disputes on an individual basis and waive any right to participate in a class action lawsuit or class-wide arbitration.

21. Force Majeure

Neither party shall be liable for failures or delays resulting from events beyond reasonable control, including natural disasters, acts of war, government orders, pandemics, or widespread internet outages. Because Dataset Reality Check operates locally, force majeure events affecting internet connectivity do not impact core application functionality.

22. General Provisions

Severability: If any provision is found invalid or unenforceable, the remaining provisions continue in full force.
Entire Agreement: These Terms, together with the Privacy Policy, constitute the entire agreement and supersede all prior communications.
Assignment: You may not assign these Terms without prior written consent. The Company may assign in connection with a merger, acquisition, or sale of substantially all assets with 30 days’ notice.
Waiver: Failure to enforce any provision does not constitute a waiver.
Notices: To the Company: privacy@detailedindesign.com. To Customer: the email address on file.
