Effective Date: February 22, 2026  ·  Last Updated: February 22, 2026

Important Legal Disclaimer Stonepath is a professional software tool. It does not constitute legal advice, tax advice, or financial advice. Output produced by Stonepath must be reviewed by a licensed attorney, certified public accountant, or other qualified professional before being relied upon in any legal proceeding, filing, or negotiation. Results are estimates only.

Please read these Terms of Service and End User License Agreement ("Agreement") carefully before accessing or using the Stonepath software platform ("Stonepath," "Service," or "Software"), operated by Stonepath ("Company," "we," "our," or "us"). By creating an account, clicking "I Agree," or using any part of the Service, you ("User") agree to be bound by this Agreement in its entirety. If you do not agree, do not use the Service.

Part 1 — Terms of Service

1. Description of Service

Stonepath is a web-based legal and financial calculation platform designed for use by attorneys, paralegals, and other legal professionals practicing in the State of California. The Service includes tools for:

2. Eligibility

You must be at least 18 years old to use the Service. By using Stonepath, you represent and warrant that you have the legal capacity to enter into this Agreement and that your use will comply with all applicable laws and regulations. The Service is intended for use by licensed legal and financial professionals or supervised legal staff. Use by unrepresented parties in litigation without professional supervision is strongly discouraged.

3. Account Registration

You agree to provide accurate, current, and complete information during registration and to keep your account information updated. You are responsible for maintaining the confidentiality of your login credentials and for all activity that occurs under your account. You agree to notify us immediately at stonepath.app+security@gmail.com of any unauthorized use of your account.

4. Subscription Plans and Billing

4.1 Free Tier

A limited-feature free tier may be available. After any applicable trial period, free accounts may have reduced functionality, watermarked output, and limited case storage. The Company reserves the right to modify or discontinue free-tier availability at any time with reasonable notice.

4.2 Paid Subscriptions

Paid plans are billed in advance on a monthly or annual basis as selected at checkout. All prices are in U.S. dollars. Annual subscriptions receive a discount versus the equivalent monthly rate. By subscribing, you authorize us (or our payment processor) to charge the applicable fee to your payment method on a recurring basis until you cancel.

4.3 Firm Plans and Seat Licensing

Firm plan subscriptions include a specified number of user seats. Additional seats may be purchased at the per-seat rate applicable to your billing cycle. Seats are non-transferable between unaffiliated organizations. Seat counts are validated at login; sharing credentials between multiple individuals violates this Agreement.

4.4 Cancellation and Refunds

You may cancel your subscription at any time through your account settings. Cancellation takes effect at the end of the current billing period; no partial-period refunds are provided unless required by applicable law. Annual subscriptions cancelled within 14 days of the initial purchase date may be eligible for a prorated refund at the Company's discretion. Contact stonepath.app+billing@gmail.com for billing inquiries.

4.5 Price Changes

The Company may change subscription prices with at least 30 days' advance written notice (by email or in-app notification). Continued use after the effective date constitutes acceptance of the new pricing.

5. Acceptable Use

You agree not to:

6. Professional Responsibility and No Legal Advice

Stonepath provides calculation tools for use by licensed professionals. Nothing in the Service or its output constitutes legal advice, tax advice, financial advice, or a substitute for independent professional judgment. Users are solely responsible for verifying the accuracy of all calculations and for complying with applicable professional responsibility rules, including rules governing competence, candor, and supervision of staff.

The support calculator tools are designed to follow California Family Code guideline formulas. However, courts may exercise discretion to deviate from guideline. The Company makes no representation that Stonepath's output will match any particular court's calculation or ruling.

7. CRC Rule 5.275 and Certified Software

California Rules of Court, Rule 5.275, governs the use of computer software for calculating guideline child support. Certain Stonepath tools may or may not hold certification under CRC Rule 5.275 for a given certification period. Users must independently verify the current certification status of any tool before relying on that tool's output in a California court proceeding. We will indicate within the applicable tool interface whether it is currently certified. Presenting results from a non-certified tool as certified program output may constitute a misrepresentation to the court.

8. Tax Law Changes — SB 711, TCJA, and Related Federal Legislation

Effective January 1, 2025, California Senate Bill 711 conformed California law to the federal Tax Cuts and Jobs Act (TCJA) treatment of spousal support. Under currently applicable law and guidance:

Federal tax law may change, including through TCJA sunset provisions and through enacted or proposed federal legislation sometimes referred to in public reporting as the "One Big Beautiful Bill." Stonepath attempts to reflect current law in its calculations, but tax law is complex and changes frequently. Users must independently verify the applicable tax treatment for their specific client's circumstances and tax year. Stonepath's calculations do not constitute tax advice and are not a substitute for consultation with a licensed CPA or tax attorney.

9. Data and Privacy

Your use of the Service is also governed by our Privacy Policy, incorporated herein by reference. Case data you enter into Stonepath is stored for the purpose of providing the Service. We do not sell your case data to third parties. You retain ownership of your client case data. We retain the right to use anonymized, aggregated data for service improvement purposes.

You are responsible for compliance with any applicable confidentiality obligations (including attorney-client privilege and Cal. Rules of Professional Conduct, Rule 1.6) when entering client information into the Service. You should not enter information that would be inappropriate to share with a cloud-based service provider.

10. Intellectual Property

The Service, including all software, algorithms, formulas, user interface elements, and documentation, is owned by the Company and is protected by copyright, trade secret, and other intellectual property laws. This Agreement grants you a limited, non-exclusive, non-transferable license to use the Service as permitted herein. No other rights are granted.

11. Availability and Modifications

We strive for high availability but do not guarantee uninterrupted access. We reserve the right to modify, suspend, or discontinue any feature of the Service at any time, with or without notice for minor changes and with reasonable advance notice for significant changes that affect paid functionality.

12. Termination

Either party may terminate this Agreement at any time. We may suspend or terminate your account immediately upon material breach of this Agreement, including misuse of the Service, fraudulent activity, or non-payment. Upon termination, your right to use the Service ceases immediately. We will retain your data for a reasonable period (typically 90 days) to allow export, after which it may be deleted.

13. Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR ACCURACY OF RESULTS. THE COMPANY DOES NOT WARRANT THAT THE SERVICE WILL BE ERROR-FREE OR THAT ANY CALCULATION OUTPUT WILL BE ACCEPTED BY ANY COURT OR AGENCY.

14. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL THE COMPANY BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES, INCLUDING LOST PROFITS, LOSS OF DATA, MALPRACTICE LIABILITY, OR ANY OTHER LOSS ARISING FROM OR RELATING TO YOUR USE OF THE SERVICE, EVEN IF THE COMPANY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. THE COMPANY'S TOTAL CUMULATIVE LIABILITY TO YOU FOR ANY CLAIMS ARISING FROM THIS AGREEMENT SHALL NOT EXCEED THE AMOUNT YOU PAID TO THE COMPANY IN THE TWELVE MONTHS PRECEDING THE CLAIM.

15. Indemnification

You agree to indemnify, defend, and hold harmless the Company and its officers, directors, employees, and agents from and against any claims, liabilities, damages, judgments, awards, costs, and expenses (including reasonable attorneys' fees) arising out of or relating to your violation of this Agreement, your use of the Service, or your misrepresentation of calculation output to any court, client, or opposing party.

16. Governing Law and Dispute Resolution

This Agreement shall be governed by the laws of the State of California, without regard to conflict of law principles. Any dispute arising under this Agreement shall be resolved by binding arbitration under the rules of the American Arbitration Association (Commercial Rules), with proceedings conducted in Los Angeles County, California, in English. Notwithstanding the foregoing, either party may seek injunctive or other equitable relief in a court of competent jurisdiction to protect intellectual property rights.

YOU WAIVE ANY RIGHT TO A JURY TRIAL AND TO PARTICIPATE IN ANY CLASS ACTION OR REPRESENTATIVE PROCEEDING.

17. Changes to Terms

We may update this Agreement from time to time. If we make material changes, we will provide at least 30 days' notice by email or prominent in-app notice. Your continued use of the Service after the effective date of changes constitutes acceptance of the updated Agreement. If you do not agree to the changes, you must stop using the Service and cancel your subscription before the effective date.

18. Miscellaneous

This Agreement constitutes the entire agreement between you and the Company regarding the Service and supersedes all prior agreements. If any provision is found unenforceable, the remaining provisions remain in full force. Our failure to enforce any right under this Agreement is not a waiver of that right. You may not assign your rights under this Agreement without our written consent.

Part 2 — End User License Agreement (EULA)

19. Grant of License

Subject to your compliance with this Agreement and timely payment of all applicable subscription fees, the Company grants you a limited, non-exclusive, non-transferable, revocable license to access and use the Stonepath Software solely for your internal professional purposes in connection with the practice of law or related legal services in the State of California.

20. Scope of License

The license does not permit you to:

21. Updates and Versions

The Company may release updates, patches, or new versions of the Software. Such updates are part of the Service and subject to this Agreement. We reserve the right to modify the formula implementations, tax tables, and calculation logic used by the Service to reflect changes in applicable law, without prior notice, provided that we document significant methodology changes in the Service's release notes.

22. Formula Transparency and Limitations

Stonepath implements California Family Code guideline formulas and, where applicable, local county spousal support formulas based on publicly available information. Due to the complexity and interpretive nature of some formulas, and the lack of official publication for certain county formulas, results may not precisely match those of other software programs. Users should:

23. Net Disposable Income and Tax Calculations

The support calculator's Net Disposable Income (NDI) calculations are intended to approximate after-tax income using estimated tax rates for the applicable filing status and tax year. These approximations do not constitute a substitute for actual tax return analysis by a licensed CPA. Tax calculations in Stonepath are provided as estimates only and should not be used as the basis for tax return preparation or tax advice. The Company targets reasonable accuracy for typical fact patterns but makes no warranty regarding tax calculation precision for unusual, complex, or edge-case scenarios.

24. Open Source Components

The Service may incorporate open-source software components. Such components are used in compliance with their respective licenses, which are available upon request at stonepath.app+legal@gmail.com. Your use of the Service does not grant you any rights in those components beyond what their respective licenses provide.

25. Feedback

If you submit suggestions, bug reports, feature requests, or other feedback about the Service, you grant the Company a royalty-free, worldwide, perpetual license to use, incorporate, and commercialize that feedback without restriction or compensation to you.
