Terms of Use

Chassis helps you keep your project car's parts, tasks, notes, and history together. These terms explain the app's role and your responsibilities when using it.

Effective: October 28, 2026

Chassis is operated by William Tradd McCorkle, an individual developer. “Chassis,” “we,” and “us” refer to that developer when describing the provider. These terms address the released Chassis apps and the Chassis website.

Apple's standard app license

The Chassis apps distributed through the App Store are licensed under Apple's Standard End User License Agreement. These Chassis-specific terms supplement that agreement; they do not replace it or grant a different app license. If these terms conflict with the standard EULA on an app-license matter, the standard EULA controls, subject to applicable law.

Apple's terms also govern your use of the App Store. Our Privacy Policy explains how Chassis handles information. Nothing here expands the collection or use of your records described in that policy.

Records and vehicle decisions

Chassis is a recordkeeping tool. Saving a part, recording a specification, or completing a task does not verify the information or certify that a vehicle, repair, or modification is safe, roadworthy, compatible, or legally compliant.

You are responsible for checking the records you enter or import and the information you rely on when working on a vehicle. Verify specifications, procedures, and fitment with appropriate manufacturer documentation and qualified professionals. Chassis does not replace an inspection or professional mechanical, engineering, legal, or financial advice.

Purchase totals and other summaries depend on the information you provide. They are not an appraisal or a guarantee of resale value. Use the app only when it is safe to do so, never while driving or performing work that requires your full attention.

Your records and content

You retain your rights in the records, photos, files, and other content you add. You are responsible for having permission to use content you import or share and for respecting other people's privacy and intellectual property.

Using Chassis does not give us ownership of your vehicle records or permission to publish, sell, advertise with, or train models on them. App storage, private iCloud sync, exports, and support correspondence follow the Privacy Policy. Sharing an export sends a separate copy to the destination you choose; that recipient controls its copy.

Use the app and website lawfully. Do not attempt to gain unauthorized access to another person's information or interfere with the security or operation of the website. Your rights to use the app software are set out in the standard EULA.

Storage, sync, and backups

Chassis stores records on your device and can sync them through your private iCloud account when available. Sync depends on Apple's services, your account, available storage, network access, and device settings. Changes may take time to reach another device.

Keep independent backups of records that matter to you, using Chassis's export tools and a storage location you control. iCloud sync is not a substitute for an independent backup. Review exports before relying on them, and keep original source files where needed.

Device loss, storage failures, software errors, or deletion can cause records to become unavailable. We cannot retrieve your private iCloud repository for you. Deleting records in Chassis does not delete copies you previously exported or shared. These practical limits do not remove any rights or remedies you have under applicable law.

Purchases and optional tips

Apple processes App Store purchases. The App Store or system purchase sheet shows the price and applicable purchase terms before you confirm. Contact Apple about billing, purchase history, and refund requests through Apple's purchase support. Applicable consumer rights remain in place.

On iPhone, tips are optional, one-time purchases. They do not unlock features or create a subscription. A tip does not purchase priority support or a promise of future features. Deleting the app or its records does not automatically refund a purchase.

Availability and support

Features and compatibility may change with app updates, operating-system requirements, and third-party services. We do not promise uninterrupted availability, compatibility with every future device or operating system, or a particular future feature or release date.

Contact support@chassis.build for help. We do not promise a particular response time or that every issue can be resolved. Any support or other obligations required by applicable law still apply.

Warranties, liability, and your rights

The standard EULA contains the warranty disclaimers and limitations of liability applicable to the app. Those provisions apply only to the extent permitted by law. These terms do not add a separate liability cap or expand those exclusions.

Nothing in these terms excludes liability that cannot lawfully be excluded, limits mandatory consumer protections, or waives your privacy rights. These terms do not add mandatory arbitration, a class-action waiver, or a requirement to bring a dispute in a new forum. If a provision cannot be enforced, it applies only to the extent legally permitted, and the remaining provisions continue to apply.

Changes to these terms

We will post updates on this page and revise the effective date. For material changes, we will provide a prominent website notice and, when the change affects app use, notice in the app. Where agreement is required, we will obtain it before applying the change. Changes will not retroactively remove accrued rights or authorize new uses of your private records.
