Terms of Service

These Terms of Service ("Terms") govern your access to and use of the website, software, SDK, dashboard, and related services (collectively, the "Service") offered by DeltaProof, a product of Calmarin Ltd, a company registered in Israel ("DeltaProof", "we", "us"). By accessing or using the Service you agree to these Terms. If you do not agree, do not access the Service.

• "Service" — the DeltaProof website at deltaproof.ai, the SDK distributed under the package name plexdb, the compliance dashboard, the sandbox, and any related APIs, documentation, and assets.
• "Customer" — the individual or legal entity that has agreed to these Terms and that uses the Service.
• "Customer Data" — any data, content, model weights, training data, or learned adaptations submitted to or processed by Customer through the Service.
• "Documentation" — the technical documentation we make available with the Service.
• "Beta Program" — the current pre-general-availability phase of the Service, accessed via an invitation code.

DeltaProof provides infrastructure for compliance-grade memory management of language models, including runtime weight-delta capture, tag-scoped serving, time-travel reconstruction, atomic replacement, verifiable deletion, non-learning attestation, and related primitives. The Service is described in the Documentation and the Service itself.

The Service is currently offered as part of a private Beta Program. You acknowledge that:

• The Service is provided AS-IS and AS-AVAILABLE for evaluation purposes.
• The Service may contain bugs, errors, or incomplete features and may be modified, suspended, or discontinued at any time without notice.
• No service-level agreement (SLA) applies to the Beta Program.
• Compliance certificates and reports generated during the Beta Program are technical artifacts and do not, by themselves, constitute legal advice or a regulatory determination.
• You may be required to provide feedback. By providing feedback you grant DeltaProof a perpetual, irrevocable, royalty-free license to use it without restriction.

To access the Service you must create an account, currently via our authentication provider Clerk. You agree to provide accurate and complete information, to keep your credentials confidential, and to notify us promptly of any unauthorized use of your account. You are responsible for activity under your account.

You agree not to:

• Use the Service in violation of any law, regulation, or third-party right;
• Reverse-engineer, decompile, or disassemble the Service except where expressly permitted by law;
• Remove, obscure, or alter any proprietary notices, including patent-pending notices;
• Use the Service to develop a competing product;
• Resell, sublicense, or redistribute the Service without our prior written agreement;
• Probe, scan, or test the vulnerability of the Service except as part of a coordinated disclosure;
• Submit content or instructions designed to overload, disrupt, or impair the Service;
• Use the Service to process personal data without a lawful basis under applicable law;
• Use the Service to generate, train, or augment systems that produce illegal content, including child sexual abuse material, content that incites violence, or content that infringes intellectual property.

The Service, including all software, source code, designs, text, graphics, the .plx file format, the .dpkg interchange format, the API surface, AI features built into DeltaProof's own product, and the Documentation, is owned by DeltaProof and protected by copyright, trademark, trade secret, and patent law. The mechanisms underlying the Service are the subject of two provisional patent applications filed with the United States Patent and Trademark Office, comprising fifty-six (56) claims. All rights not expressly granted are reserved.

Customer Data remains the property of the Customer. The Customer grants DeltaProof a limited, non-exclusive, worldwide, royalty-free license to process Customer Data solely as necessary to provide the Service. DeltaProof does not access, copy, or use Customer model weights or training data except as instructed by the Customer through the documented API surface. Where the SDK runs on Customer infrastructure, model weights and training data never leave that infrastructure.

Any feedback, suggestions, or ideas you submit may be used by us without obligation. You assign to us all rights, title, and interest in such feedback, to the maximum extent permitted by law.

Subject to these Terms, DeltaProof grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Service for your own internal business purposes during the term of these Terms.

Each party may have access to non-public information of the other party ("Confidential Information"). The receiving party will: (i) use Confidential Information only to exercise rights and perform obligations under these Terms; (ii) protect it with at least the same degree of care it uses for its own confidential information (and no less than reasonable care); and (iii) not disclose it to third parties except to its employees, contractors, and advisors who have a need to know and are bound by confidentiality obligations no less protective than these.

Our processing of personal data is governed by our Privacy Policy. For Customers who require a Data Processing Agreement (DPA) under GDPR Art. 28, contact comply@deltaproof.ai and we will execute a DPA aligned with applicable law.

Beta Program access is currently provided without charge. Pricing for the general-availability Service is set out separately and will be communicated to you before any chargeable activity begins. Taxes (VAT, GST, etc.) are your responsibility unless explicitly included.

The Service is provided on an "AS IS" and "AS AVAILABLE" basis.

To the maximum extent permitted by law, DeltaProof disclaims all warranties, whether express, implied, statutory, or otherwise, including warranties of merchantability, fitness for a particular purpose, title, non-infringement, and any warranty arising out of course of dealing or usage of trade.

DeltaProof does not warrant that the Service will be uninterrupted, error-free, secure, or that defects will be corrected. Compliance certificates produced by the Service represent technical verifications (cryptographic hashes, audit records) and do not by themselves constitute legal advice. Customers must consult their own legal counsel for regulatory interpretation.

Capped liability and exclusion of indirect damages.

To the maximum extent permitted by law, neither party will be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including lost profits, lost revenues, lost data, loss of goodwill, or business interruption, arising out of or in connection with these Terms or the Service, even if advised of the possibility of such damages.

To the maximum extent permitted by law, each party's total aggregate liability arising out of or in connection with these Terms will not exceed the greater of (a) the fees paid by the Customer to DeltaProof in the twelve (12) months immediately preceding the event giving rise to the claim, or (b) one hundred U.S. dollars ($100). The Beta Program is currently fee-free; for Beta participants the cap is $100.

The limitations in this section do not apply to: (i) breaches of confidentiality, (ii) infringement of the other party's intellectual property rights, (iii) a party's indemnification obligations, or (iv) liability that cannot be limited under applicable law.

You agree to defend, indemnify, and hold harmless DeltaProof and its officers, agents, and affiliates from and against any third-party claims, damages, losses, and expenses (including reasonable attorneys' fees) arising out of or related to: (i) your breach of these Terms; (ii) your Customer Data, including any claim that Customer Data violates applicable law or third-party rights; (iii) your use of the Service in violation of law; or (iv) your willful misconduct.

These Terms remain in effect while you use the Service. Either party may terminate the Beta Program relationship at any time, with or without cause, on written notice. We may suspend or terminate access immediately for material breach, security risk, or as required by law.

Upon termination: your license to use the Service ends; you must stop using the Service; we may delete your data subject to legal retention obligations and the data-export window described in our Privacy Policy. Sections that by their nature should survive (IP, confidentiality, disclaimers, limitation of liability, indemnity, governing law) survive termination.

We may update these Terms from time to time. Material changes will be communicated via email to active Customers and will take effect thirty (30) days after notice (or, for Beta Program participants, immediately on posting). Continued use of the Service after effectiveness constitutes acceptance.

These Terms are governed by the laws of the State of Israel, without regard to its conflict-of-law provisions. The competent courts of Tel Aviv-Jaffa, Israel have exclusive jurisdiction over disputes arising out of or related to these Terms, except that either party may seek injunctive relief in any court of competent jurisdiction to protect its intellectual property or confidential information.

The United Nations Convention on Contracts for the International Sale of Goods does not apply.

You represent that you are not located in, under the control of, or a national or resident of any country or entity subject to applicable embargoes or trade sanctions, and that you will not export, re-export, or transfer the Service in violation of such laws.

These Terms, together with the Privacy Policy and any DPA or order-form executed between the parties, constitute the entire agreement between you and DeltaProof regarding the Service and supersede all prior agreements.

If any provision is held unenforceable, the remaining provisions will remain in full force and effect.

You may not assign these Terms without our prior written consent. We may assign these Terms to an affiliate or in connection with a merger, acquisition, or sale of assets. Any attempted assignment in violation of this section is void.

Failure to enforce any right is not a waiver of that right.

Neither party is liable for delays or failures caused by events beyond its reasonable control, including but not limited to: acts of God, war, civil unrest, cyberattacks (including denial-of-service attacks and ransomware), supply chain disruptions affecting compute or telecommunications infrastructure, internet or third-party-service failures, government actions, pandemics, and labor stoppages.

Legal notices to DeltaProof must be sent to comply@deltaproof.ai. We will send notices to the email address associated with your account.
