Terms of Service

Keystone Systems LLC · Revised, Posted, and Effective August 26, 2026

Agreement to These Terms

These Terms of Service (“Terms”) are an agreement between Keystone Systems LLC (“Keystone,” “we,” “us,” or “our”) and the person and company using FieldFaktor (collectively, “you”). FieldFaktor includes its mobile application, web workspace, websites, reports, support, and related services (the “Services”). By creating an account, accepting an Order Form, purchasing or using a credit, or using the Services, you agree to these Terms and represent that you can bind the company account.

If a signed Order Form, master services agreement, data processing addendum, or other written agreement conflicts with these Terms, the signed agreement controls for the subject of the conflict. If you do not agree, do not use the Services.

1. Our Services

FieldFaktor is a business property-inspection documentation platform for contractors and contractor companies. It helps authorized users organize projects, capture observations and media, create reports, manage teams, and use related mapping, weather, delivery, and narrative tools. Keystone does not visit or inspect property and does not make insurance coverage, causation, damage, scope, engineering, code, repair, valuation, safety, or legal determinations. You remain responsible for inspection methods, lawful access, safety, professional judgment, report review, and decisions based on output.

The Services are intended for business users who are at least 18 and located in the United States. You may use them only where lawful and authorized by your company.

2. Intellectual Property Rights

Keystone and its licensors own the Services, software, interfaces, workflows, templates, documentation, designs, trademarks, and other Keystone materials (“Keystone Materials”). Subject to these Terms and payment of applicable fees, Keystone grants you a limited, non-exclusive, non-transferable, revocable right to use the Services for your company's internal business purposes during the applicable term.

You and your company retain rights in content you lawfully submit (“Company Content”), subject to Section 10. No rights are granted by implication. Feedback may be used without restriction or payment if it does not require Keystone to disclose confidential Company Content.

3. User Representations

You represent and warrant that information you provide is accurate; you are at least 18 and authorized to bind and act for the company; you have the lawful rights, permissions, and notices needed to collect, submit, process, and share Company Content, including another person's address, contact information, location, or images; your use will comply with law and professional duties; and you will not use output as a substitute for required professional judgment.

4. User Registration

You must protect credentials and devices, maintain accurate account details, and promptly report unauthorized access. Accounts are individual and may not be shared. Company administrators may invite, suspend, remove, and manage users and may access Company Content according to company settings and agreements. You are responsible for activity under your account except to the extent caused by Keystone's breach of these Terms or applicable law.

5. Purchases and Payment

Prices, taxes, included features, and refund eligibility are shown at purchase or in a signed agreement. You authorize Keystone and its payment processor to charge the selected payment method. Payment information must be current and lawfully used. Taxes may be calculated at checkout. Except as stated in these Terms, a signed agreement, or law, fees for delivered Services are non-refundable.

The current direct offer provides five complimentary company credits and allows additional credits to be purchased for $30 each, with no seat fee, recurring subscription, or minimum purchase. This is a current offer, not a promise that future prices or promotions will remain unchanged. The price shown at checkout governs each future purchase.

6. Credits; No Subscription

One credit is consumed for the project or report package described at purchase. Complimentary credits have no cash value and are not refundable or transferable outside the company account. Purchased unused credits remain available while the company account is active and in good standing. An unused purchased credit may be refunded if requested within 30 days after purchase. A credit consumed by report generation is generally non-refundable except where Keystone fails to deliver the purchased Service or law requires otherwise. A written business agreement may set different rules and controls for that customer.

FieldFaktor does not currently use an automatically renewing subscription for the direct offer. Keystone may offer a different plan only with clear purchase terms and any consent required by law.

7. Software License

The software is licensed, not sold. You may install and use object-code copies on supported devices for authorized company purposes. You may not copy, modify, distribute, sell, lease, sublicense, reverse engineer, bypass security, or derive source code except to the limited extent a restriction is prohibited by law. Open-source components remain governed by their licenses.

8. Prohibited Activities

You may not use the Services to violate law or another person's rights; access property or data without authorization; submit unlawful, deceptive, malicious, or infringing content; harass or discriminate; transmit malware; probe or defeat security; scrape or overload the Services; impersonate another person; share credentials; resell the Services without permission; falsify inspection evidence; remove notices; or use output to misrepresent that Keystone performed an inspection or made a professional or insurance determination.

9. User-Generated Contributions

Company Content may be visible to company administrators, authorized members, and recipients selected by users. You are solely responsible for its legality, accuracy, quality, and appropriateness. Do not submit content you lack authority to use or content that violates privacy, intellectual-property, contractual, or other rights. FieldFaktor is not a public social forum, and Keystone has no duty to publish Company Content publicly.

10. License to Company Content

You grant Keystone and its providers a limited, worldwide license to host, copy, transmit, format, modify as technically necessary, analyze, create reports from, display, and deliver Company Content solely to provide, support, secure, and maintain the Services; follow authorized instructions; comply with law; and enforce these Terms. This license ends when the content is deleted from active systems, subject to company control, retention obligations, and backup rotation.

This license does not authorize Keystone or a provider to train a generalized AI model on Company Content unless the company expressly agrees in writing.

11. Mobile Application License

Your app-store provider is not a party to these Terms and is not responsible for FieldFaktor. You must comply with applicable Apple App Store or Google Play terms. To the extent required by platform terms, the platform provider is a third-party beneficiary of this section and may enforce the applicable mobile license. Keystone, not the platform, is responsible for support and claims about the app to the extent required by law and these Terms.

12. Third-Party Services and Content

FieldFaktor may use or link to payment, maps, Street View, address, weather, email, AI, app-store, and other third-party services. Their data and availability may be incomplete, delayed, inaccurate, or governed by additional terms. A link or integration is not an endorsement. You are responsible for complying with third-party terms applicable to your direct use. Keystone remains responsible for its own obligations and does not disclaim liability that law does not permit it to disclaim.

13. Service Management

Keystone may monitor the Services for security, abuse, operation, and compliance; investigate suspected violations; remove or restrict unlawful or harmful content; suspend access; and manage capacity and features. Keystone is not obligated to pre-screen all Company Content. We will exercise these rights consistent with applicable contracts and law.

14. Privacy Policy

The FieldFaktor Privacy Policy explains personal-information practices and is incorporated by reference. A signed data processing addendum controls processing terms if it conflicts with the policy or these Terms. Company administrators are responsible for providing required notices and establishing a lawful basis for Company Content they direct Keystone to process.

15. Term and Termination

These Terms continue while you use the Services. You or the company may stop using FieldFaktor and request account closure. Keystone may suspend or terminate access for material breach, nonpayment, security risk, unlawful use, harm to the Services or others, or as permitted by a signed agreement. Where reasonable, Keystone will provide notice and an opportunity to cure unless immediate action is needed for security, legal, or safety reasons.

An individual account-deletion request will be processed within 30 days after receipt and verification. It removes the user's access and personal profile information from active systems, subject to the Privacy Policy. It does not delete company-controlled projects, inspections, photographs, reports, completed transactions, billing, fraud-prevention, security, audit, legal-hold, or other records that Keystone or the company lawfully retains.

Termination does not eliminate accrued payment duties or rights that by nature survive, including intellectual property, disclaimers, limits, indemnity, disputes, and lawful retention. Company access or export after termination is governed by the signed agreement and applicable retention procedure.

16. Modifications and Interruptions

Keystone may maintain, improve, replace, or discontinue features. We may update these Terms, with additional notice or consent when required. Material changes apply prospectively as stated in the notice. The Services may be unavailable because of maintenance, third parties, connectivity, emergencies, or events beyond reasonable control. Nothing here overrides a signed service-level or commercial commitment.

17. Governing Law

These Terms and any dispute arising from or relating to these Terms or the Services are governed by the laws of the State of Texas, without regard to conflict-of-law principles. Mandatory protections that cannot lawfully be waived remain applicable.

18. Dispute Resolution

Before filing a lawsuit, the complaining party must give the other party written notice describing the dispute and requested relief and allow 30 days for a good-faith informal resolution, unless immediate injunctive or other emergency relief is reasonably necessary. Notices to Keystone must be sent to the legal email and mailing address in Section 32.

Any lawsuit arising from or relating to these Terms or the Services must be brought exclusively in a state or federal court located in or serving Harris County, Texas, or Dallas County, Texas. Each party consents to personal jurisdiction and venue in those courts. Nothing prevents either party from seeking temporary or injunctive relief for misuse of confidential information, intellectual property, or security credentials where legally permitted.

To the maximum extent permitted by applicable law, any claim arising out of or relating to the Services must be commenced within one year after the claimant knew or reasonably should have known of the events giving rise to the claim; provided that this limitation will not apply to claims for unpaid fees, misuse of intellectual property, fraud, willful misconduct, or claims that cannot lawfully be shortened by contract.

19. Corrections

Information in the Services may contain typographical, pricing, availability, or descriptive errors. Keystone may correct errors and update information, subject to honoring completed purchases and rights required by law.

20. Disclaimer

To the maximum extent permitted by law, the Services and output are provided “as is” and “as available.” Keystone disclaims implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement. Keystone does not warrant that the Services will be uninterrupted, error-free, or free of harmful components, or that output will be complete, accurate, or suitable for a particular inspection, claim, code, engineering, repair, or business decision. Some jurisdictions do not allow certain disclaimers, so they may not apply.

This disclaimer does not limit an express warranty in a signed agreement or a liability that cannot lawfully be limited.

21. Limitations of Liability

To the maximum extent permitted by law, Keystone and its officers, directors, members, employees, agents, affiliates, and licensors will not be liable for indirect, incidental, special, exemplary, punitive, or consequential damages, or lost profits, revenue, goodwill, business opportunity, or data, arising from or relating to the Services, even if advised of the possibility of those damages.

To the maximum extent permitted by law, Keystone's total aggregate liability arising from or relating to these Terms or the Services will not exceed the lesser of $50,000 or the fees paid to Keystone for FieldFaktor during the six months immediately preceding the event giving rise to the claim.

These limitations apply regardless of the theory of liability and even if a remedy fails of its essential purpose. They do not exclude liabilities that cannot legally be excluded or limited.

22. Indemnification

To the extent permitted by law, you and the company will defend, indemnify, and hold harmless Keystone and its officers, directors, members, employees, agents, affiliates, and licensors from third-party claims, liabilities, damages, judgments, losses, and expenses, including reasonable attorneys' fees, arising from Company Content; unauthorized property or data access; inspection conduct; your use or misuse of the Services; violation of law or third-party rights; or material breach of these Terms. Keystone will provide prompt notice and reasonable cooperation. The indemnifying party may control the defense, subject to Keystone's right to participate with counsel of its choice and approve any settlement that admits fault by or imposes payment, restriction, or obligation on Keystone.

23. User Data

You are responsible for the accuracy and lawful collection of Company Content and for retaining copies needed for your professional or legal obligations. Keystone uses safeguards and continuity measures but is not your exclusive records archive unless a signed agreement says otherwise. Company-controlled records may remain accessible to authorized administrators after an individual user leaves.

24. Electronic Communications and Signatures

You consent to receive agreements, notices, receipts, disclosures, and other communications electronically at the account email or through the Services. Electronic acceptance and records satisfy writing requirements to the extent permitted by law. Keep contact information current. Marketing communications, if any, remain subject to applicable consent and opt-out rules.

25. California Users and Residents

Under California Civil Code Section 1789.3, California users are entitled to a consumer-rights notice. The Services are provided by Keystone Systems LLC at the contact information in Section 32. Pricing and service information is stated in these Terms and at checkout. To resolve a complaint or receive further information, contact Keystone using Section 32.

The Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs may be contacted using the following official contact information: 1625 North Market Boulevard, Suite N 112, Sacramento, California 95834; telephone 800-952-5210 or 916-445-1254.

26. Miscellaneous

These Terms, the Privacy Policy, and incorporated or signed documents are the complete agreement for their subject. Failure to enforce is not a waiver. If a provision is unenforceable, it will be limited or severed while the remainder continues. You may not assign these Terms without Keystone's consent, except as permitted in a signed agreement; Keystone may assign them in a merger, reorganization, financing, or sale of the relevant business. No agency, partnership, employment, fiduciary, or joint venture is created. Headings are for convenience. Force-majeure events excuse delay to the extent permitted by law and signed commitments.

27. User Responsibility for Property Access and Damage

You and your company are solely responsible for permission to enter and document property, safe inspection practices, personnel qualification, legal and professional compliance, and any physical act performed at the property. FieldFaktor records user-supplied observations; Keystone does not direct field conduct or assume responsibility for property damage, personal injury, or a decision made from unreviewed output, except to the extent liability cannot be lawfully excluded.

28. Company Content and Administrative Access

As between Keystone and the company, the company retains its rights in Company Content. Individual users do not obtain personal ownership of company project records merely by creating them. Authorized company administrators may access, reassign, preserve, export where supported, or delete Company Content according to the agreement and law. Removing a team member or deleting an individual user account does not automatically delete company records. You must not use FieldFaktor to defeat a property owner's, customer's, employer's, or other party's lawful rights.

29. AI-Assisted Features

AI-assisted narrative output may be incomplete, inaccurate, or inappropriate. It is a draft aid and cannot make coverage, causation, damage, scope, engineering, repair, valuation, professional, or legal determinations. Users must review and revise output before use. Company Content will be processed for the configured feature but will not be used to train generalized models absent express written company authorization. Provider retention protections, including any zero-data-retention arrangement, apply only when available and verified for the configured production service. Do not submit content you lack authority to process.

30. Credit Rules

Credits are a limited contractual right to obtain the Service described at purchase, not currency, stored value, or property. They may not be resold, exchanged for cash, transferred outside the company account, or used after fraudulent acquisition. Keystone may correct a credit-ledger error and may suspend credits tied to a reversed or disputed payment. Complimentary credits may be changed for future accounts or offers but will not retroactively create a charge. Section 6 controls refunds and persistence.

31. Weather and Hail Evidence

Weather evidence may rely on HailBrief and public government sources. Source data can be delayed, incomplete, revised, unavailable, or too coarse to prove conditions at a particular point. Geocoding can select an incorrect or approximate location. Government sources do not endorse FieldFaktor. Weather evidence is informational and does not prove hail impact, property damage, causation, date of loss, or coverage. Users must independently review it.
