This cover page summarizes the agreement structure, core commercial terms, and the product schedules that apply to F4 customer use.

Order Form

Framework Terms: This Order Form incorporates and is governed by the Framework Terms, which consist of the Key Terms below and the Common Paper Cloud Service Standard Terms Version 2.1, incorporated by reference. Any modifications to those Standard Terms made in this Cover Page or the Attachments below will control over any conflict with the Standard Terms.
Cloud Service: F4's technical drawing analysis product and related services, including downloadable desktop software made available in the F4 Lite and F4 versions, related cloud services, secure download and update services, authentication and account services, OCR and machine-learning-assisted document processing, compliance analysis, export tools, and related documentation.
Order Date: The Effective Date.
Subscription Period: One month, automatically renewing unless ended in accordance with this Agreement.
Cloud Service Fees: Lite is offered at no charge. Full and other Product offerings may be offered on a paid subscription, pilot, trial, usage-based, or separately negotiated basis, as described in the applicable purchase flow, quote, invoice, or separate Order Form. Customer will pay Provider the applicable Fees for the selected Product tier or other agreed commercial terms. Provider may update Fees for any renewing paid subscription by giving at least 30 days' notice to Customer, and any change will apply beginning with the next Subscription Period.
Payment Process: For self-serve paid plans, Customer authorizes Provider to bill and charge Customer's payment method on file monthly for immediate payment without further approval. For invoiced or enterprise customers, Provider may invoice Customer monthly, annually, or as otherwise stated in a separate Order Form, and Customer will pay each undisputed invoice within 30 days after receipt.
Non-Renewal Notice Period: At least 30 days before the end of the current Subscription Period.
Use Limitations: Customer may use the Product only for its internal business purposes or personal lawful use, subject to the Documentation, plan restrictions, seat limits, feature gating, and any usage limits or anti-abuse controls described in the Product, purchase flow, or applicable Product Schedule. Customer may not use the Product for any unlawful purpose or in violation of applicable export-control, data-protection, privacy, security, or other legal or regulatory requirements applicable to Customer's use. Provider does not represent, warrant, or guarantee that any cloud-based sharing, storage, collaboration, transmission, or export feature of the Product satisfies EAR, ITAR, CMMC, DFARS, NIST 800-171, CUI-handling, or similar requirements. Customer is solely responsible for determining whether Customer's intended use of any cloud-based Product feature is permitted and appropriate for Customer's data, obligations, and environment.
Access Suspension and Revocation: Without limiting Provider's termination rights or other remedies under the Standard Terms or Applicable Laws, Provider may suspend, limit, deny, or revoke access to all or any part of the Product (including User accounts, cloud services, downloads, updates, entitlements, seats, and integrations) when Provider reasonably determines that doing so is necessary to address non-payment, material or suspected breach of this Agreement, abuse of the Product or usage limits, security incidents or threats, legal or regulatory obligations, export or sanctions compliance, chargebacks or payment disputes, or material operational risk. Unless Applicable Laws require otherwise, Provider has no obligation to maintain access during any suspension period. Suspension does not by itself terminate this Agreement unless Provider gives notice of termination or the Standard Terms otherwise provide.
Refunds and Credits: Except where the Standard Terms or Applicable Laws expressly require a refund or credit, Fees remain non-refundable as stated in Section 4 (Payment & Taxes) of the Standard Terms. Without limiting that section, Provider may in its sole discretion issue refunds (including full or prorated refunds of prepaid Fees), credits toward future Fees, or other commercial resolutions when Provider determines appropriate, for example in connection with disputes, duplicate charges, documented service failures at Provider's discretion, goodwill adjustments, or compliance with payment-network or Applicable Law requirements. Any such refund or credit is voluntary unless expressly required by the Agreement or Applicable Laws, and does not create an obligation to offer the same treatment in other cases.
Technical Support: Provider will provide technical support, if any, according to the applicable Product tier, in-product terms, Documentation, purchase flow, or separate Order Form. Unless otherwise stated, Lite does not include any guaranteed support response times.
SLA: No service level agreement applies unless expressly stated in a separate Order Form or posted support/SLA policy that is incorporated into this Agreement.
Professional Services: None, unless expressly stated in a separate signed statement of work or Order Form.

Attachment 1 - Desktop Software Addendum

1. Desktop Software Included in the Product

For clarity, the Product includes downloadable and installable desktop software, updates, patches, model bundles, local components, and related documentation that Customer may install and use solely as permitted by this Agreement.

2. License Scope

Subject to this Agreement, Provider grants Customer a limited, non-exclusive, non-transferable, non-sublicensable right during the applicable Subscription Period to install and use the desktop software in object-code form on devices controlled by Customer, solely to access and use the Product as permitted by this Agreement.

3. Updates

The desktop software may download, install, or require updates, patches, configuration changes, security fixes, or model bundles. Customer agrees that some Product features may require Customer to use a current or supported version of the desktop software.

4. Local Storage and Device Environment

The desktop software may store files, cached data, encrypted model bundles, logs, settings, credentials, and related Product data locally on Customer devices. Customer is responsible for maintaining the security of Customer devices and operating environments.

5. Restrictions Specific to Desktop Software

Without limiting Section 2.1 of the Standard Terms, Customer may not, and may not allow anyone else to:

bypass or circumvent license checks, access controls, plan restrictions, or feature gating;
extract, decrypt, scrape, benchmark, copy, redistribute, or republish any model bundle, model key, or protected Product component except as expressly permitted by Provider in writing;
use the desktop software or any Product component to create, train, improve, or validate a competing product or service; or
tamper with update, download, telemetry, integrity-checking, or security mechanisms included with the Product.

6. Third-Party Components

The Product may include open-source or third-party software components subject to their own license terms. To the extent required by those licenses, such terms will apply to the relevant third-party components.

7. Cloud Sharing and Regulated Data

The Product may include cloud-based sharing, storage, collaboration, download, or recipient access features for exported files or other artifacts. Unless Provider expressly agrees otherwise in a separate written agreement, Provider does not represent, warrant, or guarantee that any cloud-sharing or cloud-export feature satisfies EAR, ITAR, CMMC, DFARS, NIST 800-171, export-control, controlled-unclassified-information, or similar requirements.

Customer is solely responsible for determining whether Customer Content may be uploaded to, stored in, shared through, exported through, or otherwise processed by any cloud-based Product feature. Organizations subject to EAR, ITAR, CMMC, DFARS, NIST 800-171, CUI-handling, or similar requirements may use the Product only at their own risk and remain solely responsible for configuring their workflows and using or avoiding cloud-based Product features as appropriate for their obligations.

For clarity, the statement above is specific to cloud-based sharing and export workflows. Except as expressly stated in a separate written agreement, Provider does not make any independent representation that the Product, or any specific workflow, is compliant with any particular regulatory or security framework.

Attachment 2 - ML/OCR & Output Addendum

1. Product Features

The Product may use optical character recognition, machine learning, statistical inference, document parsing, classification, extraction, validation, and related automated processing to analyze technical drawings and related files.

2. Output Disclaimer

Customer acknowledges that OCR, machine learning, and automated analysis features may produce incomplete, incorrect, inconsistent, or misleading output. Product output is not a substitute for independent engineering, manufacturing, quality, inspection, regulatory, or professional review. Customer is solely responsible for reviewing and validating all inputs, outputs, analyses, exports, and downstream decisions before relying on them.

3. No Engineering or Professional Advice

The Product provides software assistance tools only. Provider does not provide engineering, legal, compliance certification, manufacturing approval, or other professional services merely by making the Product available.

4. Customer Content Processing

Provider may process Customer Content as needed to provide, maintain, secure, support, and improve the Product and related offerings, including document ingestion, OCR, export generation, secure sharing, troubleshooting, abuse prevention, and account administration.

5. Modification to Section 1.6 (Machine Learning)

Section 1.6 of the Standard Terms is replaced with the following:

Provider may use Usage Data to maintain, improve, enhance, secure, support, and promote Provider's products and services. Provider may also use Customer Content to provide the Product features requested by Customer, including OCR, parsing, validation, export, and sharing workflows. Provider will not use Customer Content to train generalized machine learning models for Provider's products except with Customer's express consent or as otherwise expressly described in an applicable Order Form, Product Schedule, or posted policy incorporated into this Agreement.

6. High-Risk Use

Customer will not use the Product as the sole basis for decisions in any context where an error in Product output could reasonably be expected to cause death, personal injury, environmental harm, or other high-risk outcomes.

Attachment 3 - Lite Product Schedule

1. F4 Lite Nature

F4 Lite is a self-serve version of the Product that may be offered on a free, trial, preview, pilot, or limited-feature basis.

2. Eligibility and Gating

Access to F4 Lite may be conditioned on account creation, email verification, intake or onboarding completion, anti-abuse checks, rate limits, download controls, and other eligibility requirements. Provider may deny, suspend, or limit Lite access to prevent abuse, misuse, or operational risk.

3. Feature Limits

F4 Lite may include reduced functionality, reduced storage, reduced export rights, reduced collaboration rights, reduced secure sharing functionality, reduced support, and other feature limitations determined by Provider from time to time.

4. Support and Availability

Unless expressly stated otherwise, F4 Lite is provided without any SLA, uptime commitment, or guaranteed support response time.
