Privacy Policy
Apps covered: Shop Dyno, Writer Commission, Auto Shop Calcs, and Tech App (the "Apps")
Effective date: November 9, 2026
Who operates the Apps
The Apps are operated by Darrel Draper (an individual developer; the Apps are not yet operated by a company) ("I," "me," or "my").
Privacy contact: dmdraper@gmail.com
Scope
This policy describes how information is handled when you use the Apps, including beta builds distributed through Apple TestFlight. The Apps are decision-support and calculation tools for auto-repair shop operations. They are not a point-of-sale system, shop-management system of record, payment processor, or human coaching service.
Information the Apps handle
Information you enter
Depending on which App you use, you may type in shop operating numbers (such as labor rates, hours, capacity, sales figures, or tire/gear sizes), service-writer commission inputs, or other figures you choose to enter. You could also type optional notes such as a name or vehicle reference. You control what you enter.
Where that information stays
App data you enter stays on your device, except Shop Dyno numbers you choose to send to OpenAI or Anthropic, as described below. The Apps do not create accounts, do not sync your entries to my servers, and do not use a backend I operate. If you back up your device (for example with iCloud Backup), Apple's backup may include app data under Apple's terms.
Optional AI insights in Shop Dyno
Shop Dyno is the only App with AI features. Writer Commission, Auto Shop Calcs, and Tech App have no AI features.
- On-device by default. Shop Dyno's default AI option is Apple Intelligence, which runs on your device. With that option, your numbers do not leave your device.
- Optional outside AI, only with your own key. You can instead choose OpenAI or Anthropic. These options work only after you enter your own API key from an account you set up with that provider. Without a key, nothing is sent to OpenAI or Anthropic.
- Only when you tap. Data is sent only when you tap an AI option, such as "Analyze with AI" or an AI button on a KPI. The App labels these options to show that the page's numbers will be sent to the provider you chose. Nothing is sent in the background.
- What is sent. When you use OpenAI or Anthropic, Shop Dyno sends the numbers needed for that analysis: the period or month label, your KPI figures (for example sales, gross profit dollars and percent, effective labor rate, net, car count, and hours), each KPI's goal and status, sales needed per day, and how many KPIs are on goal. For a single-KPI analysis, it also sends that KPI's formula and up to 7 recent daily values.
- What is not sent. Shop Dyno does not send your shop name, your owner profile (name, email, or phone), employee, service-writer, or technician names, or individual pay records.
- Who receives it. The data goes directly from your device to the provider you chose. It does not pass through any server I operate, and I do not receive or store your data, your requests, or the AI's responses.
- Provider terms apply. OpenAI or Anthropic handles the data under its own terms and privacy policy, including how long it keeps the data and whether it may be used to improve its models. Review those terms and your account settings: OpenAI privacy policy (https://openai.com/policies/privacy-policy) and Anthropic privacy policy (https://www.anthropic.com/legal/privacy).
- Your API key. Your key is stored on your device in the iOS Keychain. It is sent only to that provider to authorize your requests, and never to me.
- AI output can be wrong. AI insights are informational only. They are not financial, tax, legal, accounting, or payroll advice, and they may contain mistakes. Check important numbers before acting on them.
Information collected through TestFlight / Apple
When you install a beta through Apple TestFlight, Apple's TestFlight terms apply. Crash data and statistics about how you use the App may be provided to me and linked to your email address, and I may contact you about that information. Feedback you submit through TestFlight may also be shared with me. Apple may use crash and usage information to improve its own products and services.
Purchases
If you buy an in-app purchase or subscription through the App Store (for example, the one-time tire calculator unlock in Auto Shop Calcs), payment is processed by Apple. I may receive purchase or entitlement status from Apple. I do not receive your full payment-card number.
What I do not collect
I do not seek government IDs, precise GPS location, contacts, photos, microphone or camera content, or health data. The Apps do not use third-party analytics or crash-reporting SDKs beyond Apple's own frameworks and TestFlight. Apart from Shop Dyno's optional OpenAI or Anthropic requests and Apple's App Store purchase system, the Apps make no network connections.
How information is used
I use information only to:
- Provide the calculations and features you request on your device
- Send Shop Dyno numbers to OpenAI or Anthropic when you choose that option and tap an AI button, as described above
- Review TestFlight crash reports, usage statistics, and feedback so I can fix bugs and improve the Apps
- Contact beta testers about testing issues when appropriate
- Verify purchases or entitlements through Apple
- Comply with law and Apple platform requirements
I do not sell your information.
Sharing
I do not sell personal information and do not share identifiable shop, employee, or customer data with advertising networks.
Information may be shared only with:
- Apple (TestFlight, App Store, purchases, and related platform services), under Apple's terms and privacy policy
- OpenAI or Anthropic, only if you choose that provider in Shop Dyno, add your own API key, and tap an AI option, sent directly from your device under that provider's terms
- When required by law, court order, or to protect rights, safety, or security
- If the project later moves into a company or is transferred, under continued privacy protections
Retention
- On-device entries: remain until you delete them in the App, delete the App, or clear related device data.
- Shop Dyno AI requests: I never receive or keep them. Your AI provider's retention rules apply to data you send it.
- API key: stays in your device's Keychain until you remove it in the App or delete the App.
- TestFlight crash, usage, and feedback: kept only as long as needed to fix issues during testing, then deleted or anonymized when no longer needed, subject to Apple's retention of data Apple controls.
- Purchase or entitlement records from Apple: kept as needed for accounting, refunds, and Apple reconciliation.
Your choices and deletion
You may:
- Stop using an App and delete it from your device
- In Shop Dyno, switch back to Apple Intelligence or remove your API key at any time to stop sending data to OpenAI or Anthropic
- Leave a TestFlight beta and manage TestFlight notifications in Apple's TestFlight app
- Ask to be removed from a tester list by emailing dmdraper@gmail.com
- Email dmdraper@gmail.com to ask about personal information I hold from TestFlight (for example your tester email and related crash or feedback records)
Because calculation data stays on your device (apart from Shop Dyno AI requests you choose to send), deleting the App (or clearing its data) removes that local information from the device.
Children
The Apps are built for auto-repair shop professionals and business users. They are not directed to children under 13, and I do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided personal information, email dmdraper@gmail.com and I will delete it.
Security
The Apps rely on your device's operating-system protections and Apple's platform security. No method of storage is 100% secure. Beta software may crash or cause data loss; do not rely on a beta build as your only copy of important shop records. If you enter real employee, customer, or vehicle details while testing, use a device you control and avoid sharing screenshots that identify other people.
U.S. privacy rights
Depending on where you live, you may have rights to know, access, correct, or delete certain personal information, or to opt out of certain processing. To make a request about information I hold (such as TestFlight-related records), email dmdraper@gmail.com. I will not discriminate against you for exercising privacy rights.
International users
The Apps are aimed at U.S. independent auto-repair shops. If you use them from another country, information handled by Apple (including TestFlight) may be processed in the United States.
Changes
I may update this policy as the Apps change. When I do, I will revise the effective date above and, for material changes, provide additional notice when appropriate (for example in the App or TestFlight notes). Continued use after an update means you accept the revised policy.
