Terms of Service

Last updated: September 15, 2026

These terms apply when you use WrenchStrike, an iPhone and iPad app published by HOMERUNUNIT L.L.C., a Michigan limited liability company ("we", "us"). By downloading or using the app, you agree to them. If you do not agree, do not use the app.

What WrenchStrike is

WrenchStrike is a record-keeping tool for independent mechanics. It helps you write estimates, send invoices, record payments and organize your own numbers. It is software you use to do your own work. It is not a service we perform for you.

Your work and your customers

WrenchStrike is only a tool for preparing estimates, invoices and records. We are not a party to any agreement between you and your customers, and we are not involved in the repair work, the price, the quality of the work, any warranty you give, or any payment between you and your customer. Any dispute about a job, a charge or a payment is between you and your customer.

It is not tax, legal or accounting advice

WrenchStrike includes sales tax calculations and a Schedule C summary. These are arithmetic tools that use the information and tax rates you enter. Tax rules vary by state, city and situation, and they change. We do not verify your rates, your categories or your figures.

You are responsible for the sales tax you charge, collect and remit, for what you report on your tax return, and for confirming all of it with a qualified tax professional. Do not rely on WrenchStrike as your only source for any tax decision.

Your account and your data

Your data lives on your device and, if you enable it, in your own iCloud account. We do not host your customer records. Backup and restore depend on Apple's iCloud service, your device and your settings, and we cannot guarantee they will always work. Keep your own copies of anything you cannot afford to lose.

Your content

Everything you type or add in WrenchStrike, including invoice and estimate wording, warranty text, footer notes, business details, prices, photos, signatures and customer information, belongs to you. You are responsible for that content, for making sure it is accurate and lawful, and for having any rights or permissions it requires, including permission to store and use your customers' information. We do not review or approve it.

Payment and subscriptions

WrenchStrike is free to try. Paid subscriptions are sold through Apple and billed by Apple to your Apple Account. Prices are shown in the app before you buy. Manage, cancel or request a refund for a subscription through your Apple Account settings or by contacting Apple. We cannot process refunds for purchases Apple handled.

What you may not do

Do not use WrenchStrike to break the law, to create false or fraudulent records, or to harass anyone. Do not attempt to reverse engineer, resell or redistribute the app.

No warranty

WrenchStrike is provided "as is". We do not warrant that it will be uninterrupted, error free, or that every calculation, PDF or export will be correct for your situation. To the fullest extent allowed by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose and non-infringement.

Limit of liability

To the fullest extent allowed by law, HOMERUNUNIT L.L.C. is not liable for lost profits, lost data, lost business, tax penalties, interest, or any indirect, incidental, special or consequential damages arising from your use of WrenchStrike. Our total liability for any claim will not exceed the greater of the amount you paid for the app in the twelve months before the claim, or twenty-five US dollars.

Some states do not allow certain limits, so parts of this section may not apply to you.

Changes to the app and to these terms

We may update, change or discontinue features. We may update these terms; when we do, we will change the date at the top of this page. Continuing to use the app after a change means you accept the updated terms.

Ending your use

You may stop using WrenchStrike at any time by deleting it. We may suspend or end your access if you break these terms.

Governing law

These terms are governed by the laws of the State of Michigan, without regard to its conflict of law rules. Any dispute will be brought in the state or federal courts located in Washtenaw County, Michigan, and you and we agree to the personal jurisdiction of those courts.
