Terms of Service — CF-SCOPED-2026-09-21.1

1. Seller, scope and acceptance

Sunnyday Technologies LLC is a Wisconsin limited liability company in the United States, solely owned by Nick Sonnentag. “Sunnyday,” “we” and “us” mean the LLC. CEMFORGE and LOGiMIX identify its products and services; they are not separate contracting entities. Contact cemforge@sunn3d.com for sales, support and legal-notice intake.

These terms apply to a new Datapack sale or related service only when the exact policy version is supplied to the customer and expressly incorporated into a written order accepted by both parties. Browsing, making an inquiry, receiving a quote, downloading a free example, holding a credential or having an agent read this page does not itself accept a paid order. We do not create a subscription or recurring charge through this website.

An individual must have legal capacity to contract under applicable law. A person ordering for an organization must have authority to bind it. We serve business customers and individual consumers, subject to the product, intended use and location checks below. Calling a customer a business does not remove consumer protections that apply by law.

2. Your written order

Before you commit, the written order will identify the seller and required business contact details, customer, product and version, deliverables, included support, permitted use, inputs, format and compatibility requirements, delivery method and timing, access duration or expiry, total price, currency, applicable taxes and fees, payment schedule, cancellation rights and any special conditions. It must distinguish a fixed deliverable from prepaid API access, a hosted delivery service or professional services. An advertised example or estimated price is not an accepted order.

We will confirm the nonprivate geographic business address and other seller details required by applicable law in the pre-contract documents. Any public-offer disclosure required by applicable law must also be satisfied before making that offer. Where local law requires disclosures, a withdrawal notice, translations, particular consent or another step, the sale will not be concluded until those requirements can be met. Availability worldwide means inquiries are welcome; it does not mean every product or transaction is available in every jurisdiction.

The order expressly incorporates this version, the Datapack License, Cancellation and Refund Policy and Data Handling Statement. A negotiated order provision prevails over a conflicting standard commercial provision only where the order clearly identifies the change and law permits it. Mandatory law prevails. The Privacy Notice explains processing; acknowledging it is not consent to optional uses.

We provide a durable copy of the accepted order and incorporated policies. Changes to scope, price, deliverables or delivery require written agreement. A later website edit does not retroactively change an accepted order. Please retain your order and policy copies.

3. Products, evidence and limitations

A Datapack may contain a versioned digital record, modeled output, evidence summary, provenance, uncertainty fields or a specified hosted rendering, as described in its order. A synthetic example is illustrative data, not a measurement or project result. An Open Benchmark Mix Card may use a separately licensed open source record; any charge must identify the additional hosted delivery or support service. Purchasing that service does not narrow the open license.

Model outputs are decision support requiring physical validation. They may be incomplete, inaccurate or outside the model’s useful domain. Confidence metrics describe a computation; they are not a probability of project success or a guarantee of performance. We do not promise a new model run, access to a particular model or dataset, continued hosting, updates or API access unless the order includes it.

Before batching, printing, construction, structural, safety-critical or other real-world use, you and appropriately qualified professionals must assess the input rights and suitability, characterize the actual materials and equipment, and perform project-specific trial batching and physical testing. Outputs do not establish strength, printability, pumpability, buildability, durability, environmental performance, code compliance, safety, certification, fitness for purpose or freedom to operate under third-party patents.

CEMFORGE does not provide licensed engineering, architectural, legal or regulatory advice through these products. These limitations describe the product’s intended use; they do not exclude statutory quality, description, fitness, care or other guarantees that cannot lawfully be excluded.

4. Prices, payment and delivery

Only the accepted order establishes a payment obligation. It specifies an authorized payment method and when payment is due. No card details, wallet secrets or payment credentials should be sent by email. This website does not operate public self-service checkout, and publication of these terms does not authorize automated payments.

Required sales tax, VAT, GST or similar transaction taxes and unavoidable charges will be disclosed before acceptance as applicable, including the total payable or legally permitted calculation method. A business must supply accurate tax status and any valid exemption evidence. We may decline or pause a proposed sale when tax or eligibility requirements cannot be resolved.

We deliver through the method and by the date or period agreed in the order. Report inaccessible, corrupted, missing or incorrect delivery so we can investigate and provide a remedy. A receipt, payment settlement or access credential alone is not evidence of complete delivery or conformance. There is no automatic renewal; any recurring arrangement requires a separate express agreement.

5. Customer materials, confidentiality and rights

You retain your rights in submitted materials. You grant us only the permissions needed to perform the agreed work and meet applicable legal obligations. Provide accurate information and ensure you have authority to supply it. Start inquiries without confidential, sensitive personal, export-controlled or safety-critical project information. Agree a suitable transfer method and handling terms before sending project material.

Each party will use the other’s identified confidential information only for the agreed work, protect it with reasonable care, and disclose it only to people and authorized providers who need it and are subject to appropriate duties. This does not cover information already lawfully known, independently developed, publicly available without breach, or lawfully received without restriction. Legally compelled disclosure may be made, with notice where lawful and practicable.

Customer inputs and outputs are not licensed for general model training, public benchmarking, case studies or marketing by ordering a Datapack or acknowledging a privacy notice. Any such use requires a separate, specific permission or data-contribution agreement. Open material retains its stated license. Neither party acquires the other’s pre-existing intellectual property by this transaction.

6. Permitted use and access

The Datapack License governs use of delivered material. Do not use the service unlawfully, submit material without rights, bypass access or metering controls, share credentials, extract restricted models or datasets, or misrepresent modeled or synthetic data as tested performance. Restrictions apply only to the extent permitted by law and do not override rights in separately licensed open material.

An order including API access must specify quotas, duration, metering, failed-request treatment, credential recovery and suspension. Such access is not included by default. We may proportionately restrict access to address a material breach, genuine security risk, unpaid agreed charges or a legal requirement. Where feasible and lawful, we give reasons, an opportunity to correct the issue and a route to human review. Undisputed consumer remedies and appropriate refunds remain available.

7. Cancellations and remedies

The Cancellation and Refund Policy applies alongside your order and mandatory law. We do not apply a blanket “all sales final” rule. Statutory withdrawal, cancellation, conformity, repair, replacement, price-reduction, refund and compensation rights remain available where applicable.

A customer’s request for early digital delivery does not itself waive a withdrawal right. Any legally permitted loss of that right requires the applicable prior information, express consent, acknowledgment and durable confirmation. Custom digital work is not automatically treated as exempt personalized goods.

8. Responsibility and liability

We are responsible for performing the accepted scope and providing any remedies required by the order and applicable law. We do not guarantee real-world outcomes from modeled or illustrative information. You are responsible for decisions outside the agreed scope, the materials and permissions you supply, and the physical validation and professional oversight described above.

For a business customer, any negotiated liability cap, exclusion or indemnity must be stated expressly in the accepted order. These standard terms impose no automatic monetary liability cap and no broad customer indemnity. We do not exclude liability that cannot lawfully be limited, including applicable liability for fraud, deliberate misconduct, death or personal injury, or mandatory consumer guarantees. A disclaimer elsewhere in a historical document does not override this section for a new order incorporating this version.

Nothing here prevents a consumer from seeking legally available remedies, contacting a regulator, using a payment-dispute process or accessing a competent court. Remedies are assessed under the law applicable to the transaction.

9. International availability and trade controls

Inquiries are welcome internationally. Supply is conditional on applicable local law, sanctions and export controls, tax treatment, privacy requirements, product restrictions and consumer rights. We may seek the minimum information necessary to assess customer, destination, end user and intended use, and may decline or hold a transaction that cannot lawfully proceed.

Do not use an intermediary, agent or inaccurate location or ownership information to evade restrictions. Screening and customer attestations assist review; they do not certify legal clearance. If an accepted order later cannot lawfully proceed, we will notify you where allowed and address undelivered work and payments as applicable law permits or requires. We do not require a customer to forfeit a legally owed refund merely because a compliance review occurs.

10. Agents and automated channels

A software agent may help prepare an inquiry. A customer’s human representative must approve the scoped order and have authority to do so. Public agent guidance, a protocol manifest, a model response or a payment signature does not by itself establish the authority and acceptance required for a scoped order under these terms.

Production MCP/ACP purchasing and mainnet x402 purchases are not offered under this policy. Any future automated channel requires separately approved and published checkout terms, evidence of the buyer’s bounded authority, applicable disclosures and consent, price/resource/version binding, and appropriate cancellation, refund and privacy controls. Test or sandbox records are qualification evidence, not proof of a live sale.

11. Ending work, disputes and governing law

Either party may end an order for a material breach that is not corrected within a reasonable written cure period, or when continued performance would be unlawful. A serious security issue may justify an immediate proportionate suspension. We will address delivered work, undelivered balances, data return or deletion and any continuing confidentiality or license rights under the order, Refund Policy and applicable law. Force majeure does not remove mandatory remedies; we will communicate material delays and agree a lawful resolution.

For concerns, contact cemforge@sunn3d.com with the order reference and requested resolution. Informal discussion is encouraged but is not a prerequisite that delays statutory deadlines or access to remedies. These standard terms impose no mandatory arbitration, class-action waiver or exclusive Wisconsin forum on consumers.

Wisconsin law governs to the extent a choice of law is permitted, without depriving a consumer of mandatory protections of an otherwise applicable jurisdiction. Consumers retain any mandatory right to bring proceedings in their home courts. For business transactions, forum or dispute-resolution provisions may be agreed in the written order. If a provision is unenforceable, the remainder applies to the extent lawful; invalid consumer terms will not be rewritten to defeat mandatory protections.

12. Versions and existing agreements

This is policy suite CF-SCOPED-2026-09-21.1. Its version date identifies the text, not a retroactive start date. The policy register identifies each document and its role. For sales, the accepted order records the version and acceptance time.

Existing contracts, historical policy acceptance records, accrued rights and statutory obligations remain governed by the applicable agreement and law. This publication does not relabel old acceptance records or make a retired subscription policy current. Future automated-checkout candidates are not incorporated into a scoped sale merely because they are retained in development records.

Legal notices may be initiated at cemforge@sunn3d.com; use a notice method required by your agreement or applicable law. An email intake address does not replace a mandatory pre-contract geographic address or formal service requirement.
