Terms of Use

Effective Date: July 25, 2026 Last Updated: August 22, 2026

These Terms of Use ("Terms") are a legal agreement between you ("you," "user") and D73 ("we," "our," "us"), the independent developer of the mobile application distributed with iOS bundle identifier com.d73.cdl on the Apple App Store and, if published, on Google Play (the "App").

Why these Terms do not print a product name. The store listing and the name

shown on your device may change; the bundle identifier com.d73.cdl does not.

These Terms therefore identify the App by that identifier, so they cannot fall

out of date with the product they govern.

By downloading, accessing, subscribing to, or using the App, you agree to these Terms. If you do not agree, do not use the App.

1. The App

The App is a study companion for commercial driver (CDL) exam preparation. The App may include reading chapters, practice quizzes, mock exams, personalized study plans, progress analysis, and reminders.

The App is designed for educational and exam-preparation support only.

2. Important Disclaimer

The App is an independent study aid. It is not an official or certifying service.

• The App is not affiliated with, endorsed by, or sponsored by the Federal Motor Carrier Safety Administration (FMCSA), the U.S. Department of Transportation, the American Association of Motor Vehicle Administrators (AAMVA), or any state Department of Motor Vehicles or licensing agency.
• Those names are used only to identify the tests this App helps you study for.
• The App does not register you for your CDL knowledge tests, issue a commercial learner's permit or CDL, provide Entry-Level Driver Training (ELDT), or replace your state's official driver manual.
• Practice questions, quizzes, mock exams, readiness scores, and study plans are not a guarantee that you will pass the official CDL knowledge test.
• App content is written from public state CDL manuals and may be incomplete, imperfect, outdated, or AI-assisted in its authoring. You are responsible for verifying important information against your state's official CDL manual.
• The App does not provide medical, clinical, behavioral-treatment, legal, employment, or professional advice.

3. Eligibility

You may use the App only if you can legally enter into these Terms. The App is intended for adults preparing for a professional certification and is not directed to children under 13.

If you use the App on behalf of another person or organization, you represent that you have authority to accept these Terms on their behalf.

4. No Professional Relationship

Your use of the App does not create a therapist-client, supervisor-supervisee, certification, training, employment, healthcare, legal, or other professional relationship with D73.

Any quiz explanation, study recommendation, or readiness estimate is provided for study support only.

5. Account and Device-Based Access

The App may identify your account using a device identifier and local installation credential instead of a traditional email/password login.

You are responsible for maintaining control of your device and for any activity that occurs through your installation of the App.

Because the App may use device-based identification, deleting the App, clearing device data, changing devices, restoring from backup, or reinstalling may affect local data, sync, or access behavior.

6. Premium Subscriptions

The App may offer optional Premium access through auto-renewing subscriptions, and may include an introductory or free-trial period.

Why these Terms print no price, no plan length, and no trial length. Every

one of those is set in App Store Connect and can change — for a promotion, a

price test, or a new plan we have not built yet. The App reads all of them live

from the store at the moment you look, so what you see on the purchase screen is

always the truth for you, in your currency, for your region. If we also printed

a figure here it would eventually contradict the one you are charged, and a

published document that contradicts the checkout screen is a false claim about

price, not a typo. The purchase screen governs. It shows the exact plans on

offer, their durations, their prices, and any trial or introductory terms before

you confirm anything.

6.1 Payment Processing

Payments are processed by the Apple App Store on iOS or Google Play on Android. We do not store your full payment card details.

6.2 RevenueCat

We use RevenueCat to manage subscription status, purchase verification, trial tracking, renewal status, cancellations, restorations, and entitlement state.

RevenueCat and the app stores are the source of truth for paid access. The App and our backend use RevenueCat subscription status to unlock Premium features.

6.3 Auto-Renewal

• Subscriptions renew automatically unless cancelled.
• To avoid being charged, you must **cancel at least 24 hours before the end of the current period**, through your Apple App Store or Google Play account.
• Your account is **charged for renewal within 24 hours prior to the end of the current period, at the then-current price** shown by the store.
• A free trial converts automatically into a paid subscription unless you cancel before the trial ends.
• If you buy a subscription during a free trial, **any unused portion of the trial is forfeited**.
• Managing and cancelling subscriptions is done in your store account settings, not in the App. Refunds are handled by Apple or Google, not by us — for Apple, see https://reportaproblem.apple.com.

6.4 Trials

If a free trial is offered, trial eligibility and duration are determined by the app store and RevenueCat. After the trial ends, the subscription may automatically renew unless cancelled before the trial or billing period ends.

6.5 Pricing

Subscription prices, durations, currency, taxes, and trial availability are shown in the App using information loaded from the app stores through RevenueCat. Prices may vary by country, currency, tax rules, store account, promotions, or app-store configuration.

6.6 Cancellation

You must cancel subscriptions through the Apple App Store or Google Play. Deleting the App does not automatically cancel your subscription.

• iOS: Settings > Apple ID > Subscriptions
• Android: Google Play > Profile > Payments & subscriptions > Subscriptions

6.7 Refunds

Refunds are handled by Apple or Google Play according to their policies. We do not control app-store refund decisions.

6.8 Restore Purchases

The App may provide a restore-purchases option. Restore depends on the app store, RevenueCat, your store account, and your subscription status.

7. Acceptable Use

You agree not to:

• Use the App for unlawful, harmful, fraudulent, abusive, or misleading purposes.
• Attempt to bypass paywalls, subscription checks, rate limits, security controls, or backend access controls.
• Reverse engineer, decompile, modify, resell, copy, scrape, or redistribute the App or its content except as allowed by law.
• Use automated tools, bots, scripts, or excessive requests that burden the App or backend.
• Send support messages that are illegal, harmful, abusive, hateful, threatening, infringing, or otherwise inappropriate.
• Misrepresent the App as official FMCSA, AAMVA, or state DMV material, or use it to provide unauthorized certification or training services.

We may limit, suspend, or terminate access if we believe you violated these Terms or are abusing the App or backend.

8. Where the Content Comes From

The App's written course content was authored with AI assistance and edited against public state CDL manuals. It may still be incomplete, imperfect, or outdated. You should not rely on it as official exam guidance, professional advice, legal advice, or a substitute for your state's official CDL manual.

You are responsible for verifying important information.

9. Study Content and Intellectual Property

The App, including its design, code, text, explanations, study plans, question formats, graphics, branding, and other materials, is owned by D73 or its licensors and is protected by intellectual-property laws.

Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable, revocable license to use the App for your own study purposes.

You may not copy, sell, publish, redistribute, create competing datasets from, or train models on App content without our written permission.

10. User Content

You may enter information such as onboarding answers and quiz activity. Support is by email, sent from your own email application.

You retain any rights you have in content you submit. You grant us a limited right to host, process, transmit, analyze, and display that content as needed to provide, secure, support, and improve the App.

You are responsible for the content you submit and must not submit content that violates law, infringes others' rights, or contains sensitive information you do not want processed by the App.

11. Privacy

Your use of the App is also governed by our Privacy Policy:

https://cdl-prep-api.fly.dev/legal/privacy

The Privacy Policy explains what data we collect, how we use it, how subscription status is synced, and how to request deletion or access.

12. Availability and Changes

We may modify, suspend, discontinue, or limit any part of the App at any time, including features, content, pricing, subscriptions, backend services, or support availability.

We may update content, fix errors, change study plans, adjust feature access, and improve or remove features without notice.

We do not guarantee that the App will be uninterrupted, error-free, available on every device, or compatible with every operating-system version.

13. Third-Party Services

The App may rely on third-party services including Apple, Google Play, RevenueCat, Mixpanel, Fly.io, Google Cloud, and Firebase.

Third-party services are governed by their own terms and privacy policies. We are not responsible for third-party service outages, decisions, policies, refund handling, store account issues, sandbox account behavior, or app-store subscription processing.

14. No Warranty

The App is provided "as is" and "as available," without warranties of any kind, express or implied.

To the fullest extent permitted by law, we disclaim warranties of merchantability, fitness for a particular purpose, accuracy, completeness, availability, non-infringement, and uninterrupted or error-free operation.

15. Limitation of Liability

To the fullest extent permitted by law, D73 will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost data, lost opportunities, exam results, certification outcomes, business losses, or damages arising from your use of or inability to use the App.

Where liability cannot be excluded, our total liability will be limited to the amount you paid for the App or subscription during the three months before the claim, or the minimum amount allowed by law.

16. Indemnity

You agree to defend, indemnify, and hold harmless D73 from claims, losses, liabilities, damages, costs, and expenses arising from your use of the App, your content, your violation of these Terms, or your violation of any law or third-party rights.

17. Account Deletion and Termination

You may request account deletion as described in the App or Privacy Policy. We may terminate or restrict access if you violate these Terms, misuse the App, attempt to bypass payment or security controls, or create risk for us, other users, or third-party services.

Termination does not automatically cancel an active app-store subscription. You must cancel subscriptions through Apple or Google Play.

18. Apple-Specific Terms

This section applies when you obtain or use the App through Apple's App Store. It sets out, in full, the minimum terms Apple requires a custom End User License Agreement to contain. Where this section conflicts with anything earlier in these Terms, this section governs for App Store users.

18.1 Acknowledgment

These Terms are concluded between you and D73 only, and not with Apple. D73, not Apple, is solely responsible for the App and its content. These Terms do not provide for usage rules for the App that conflict with the Apple Media Services Terms and Conditions in force at the date you obtain the App; where they would, the Apple terms prevail.

18.2 Scope of License

The licence granted to you in these Terms is limited to a non-transferable licence to use The App on any Apple-branded product that you own or control, and as permitted by the Usage Rules set out in the Apple Media Services Terms and Conditions — except that the App may be accessed and used by other accounts associated with you via Family Sharing or volume purchasing, where Apple permits it.

18.3 Maintenance and Support

D73 is solely responsible for providing any maintenance and support services for the App, as specified in these Terms or as required by applicable law. Apple has no obligation whatsoever to furnish any maintenance or support services for the App.

18.4 Warranty

D73 is solely responsible for any product warranties, whether express or implied by law, to the extent they are not effectively disclaimed. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the App to you (if any). To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to The App. Any other claims, losses, liabilities, damages, costs or expenses attributable to a failure to conform to a warranty are D73's sole responsibility.

18.5 Product Claims

D73, and not Apple, is responsible for addressing any claims by you or a third party relating to the App or your possession and use of it, including: (i) product liability claims; (ii) any claim that the App fails to conform to an applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy, or similar legislation, including in connection with the App's use of any framework. These Terms do not limit D73's liability beyond what applicable law permits.

18.6 Intellectual Property Rights

In the event of any third-party claim that the App or your possession and use of it infringes that third party's intellectual property rights, D73, and not Apple, will be solely responsible for the investigation, defence, settlement and discharge of that claim.

18.7 Legal Compliance

You represent and warrant that: (i) you are not located in a country subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties. You further agree not to use or export the App in violation of applicable export-control or sanctions laws.

18.8 Developer Name and Address

Questions, complaints or claims about the App should be directed to:

D73 — connectstillalive@gmail.com

18.9 Third-Party Terms of Agreement

You must comply with any applicable third-party terms of agreement when using the App, including the terms of your wireless data plan and your internet service provider.

18.10 Third-Party Beneficiary

You acknowledge and agree that Apple, and Apple's subsidiaries, are third-party beneficiaries of these Terms, and that upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary of them.

18.11 Apple's Standard EULA

Unless D73 has supplied a custom EULA through App Store Connect, your licence is also governed by Apple's current Licensed Application End User License Agreement:

https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Where these Terms are supplied as a custom EULA, they apply in place of the standard agreement in the countries or regions selected.

19. U.S. Government End Users

The App and its documentation are "Commercial Items" as that term is defined at 48 C.F.R. §2.101, consisting of "Commercial Computer Software" and "Commercial Computer Software Documentation". Consistent with 48 C.F.R. §12.212 and 48 C.F.R. §227.7202, U.S. Government end users acquire the App with only those rights granted to all other end users under these Terms.

20. Changes to These Terms

We may update these Terms from time to time. We will update the "Last Updated" date above. Continued use of the App after changes means you accept the updated Terms.

21. Governing Law

These Terms are governed by applicable laws, without regard to conflict-of-law rules, except where local consumer-protection laws require otherwise.
