Agreement
These Terms of Use ("Terms") are a contract between you and the independent developer of UNDERGROUND (the "Developer", "we", "us") for the UNDERGROUND iOS app and its related services ("the Service"). By installing or using the app you accept these Terms and our Privacy Policy. If you do not agree, do not use the app.
Apple is not a party to these Terms and is not responsible for the app or its content. Apple's standard Licensed Application End User License Agreement also applies to your use of the app; where the two conflict, these Terms govern as far as Apple's agreement permits.
Eligibility
You must be at least 13 years old, or the minimum age required in your country to use online services without parental consent, and at least 18 (or have a parent's or guardian's consent) to make purchases.
The Service
UNDERGROUND lets you upload a photo of a car, select modifications and scene presets, and receive AI-generated images of that car with the modifications applied. Results are produced by a generative model. They are artistic visualizations: parts may not exist in the exact form shown, may not fit a real vehicle, and colours and proportions may differ from real products. Do not rely on the images for purchasing, insurance, legal, safety or engineering decisions.
We may change, suspend or discontinue features, part catalogues and presets at any time. We aim for a build to complete in seconds, but generation times and availability depend on third-party model providers and are not guaranteed.
Credits, subscriptions and coin packs
Credits
Every build costs credits: a base credit for the generation plus a fixed number of credits per selected part, shown in the app before you confirm. Scene presets have a flat price. Credits are deducted when a build starts and refunded automatically if the build fails on our side. A build that completes is final, even if you dislike the result; "Retry" is a new build and is charged again.
Starter credits
New installs receive a small number of free starter credits once. Reinstalling the app to obtain more starter credits is not permitted, and we may withhold or revoke credits obtained this way.
Subscriptions
Weekly, monthly and yearly plans grant a fixed number of credits per billing period. Unused subscription credits do not roll over: at each renewal the subscription balance is reset to the plan amount. Subscriptions renew automatically through your Apple ID until cancelled in your device's Settings at least 24 hours before the current period ends. When a subscription ends, any remaining subscription credits are converted to purchased credits and stay usable.
Coin packs
Coin packs are one-time purchases of credits that do not expire while your anonymous account exists.
Prices, taxes and refunds
Prices are shown in the App Store in your local currency and may change; changes apply to future periods only. All payments are processed by Apple and are subject to Apple's terms. Refund requests must be made to Apple through your purchase history; we cannot issue refunds directly. Credits have no cash value and cannot be transferred, sold or exchanged.
Anonymous account and loss of balance
The app works without registration and identifies you by an anonymous ID stored on your device. If you delete the app or move to a new device, that ID is lost together with the credit balance and garage tied to it. Active subscriptions can be restored with "Restore Purchases" and will grant credits for the current period again; consumed credits and coin-pack balances tied to the previous ID cannot be recovered. Do not delete the app while you hold a balance you care about.
Your content
You keep all rights to the photos you upload. You grant us a limited licence to store, process and transmit them (including to our AI provider) solely to provide the Service to you. You confirm that you own or have permission to use every photo you upload and that it does not contain other people's faces, licence plates or private information you are not entitled to share.
You must not upload content that is illegal, infringes someone else's rights, or is sexual, violent, hateful or otherwise abusive, and you must not use the Service to create misleading images of real vehicles for fraud, false advertising or insurance claims.
Generated images
Subject to these Terms, you may use the images generated for you for personal and commercial purposes, for example sharing them on social media or showing them to a body shop. You are responsible for how you use them and for complying with the rights of third parties (for example trademarks visible on wheels or liveries). Because generative models can produce similar outputs for different users, we cannot guarantee that a result is unique, and we make no claim of copyright in generated images on our own behalf.
Acceptable use
- Do not reverse engineer, scrape, or access the Service by any means other than the app.
- Do not attempt to bypass credit charges, rate limits or authentication, or to obtain credits you did not pay for.
- Do not use automated tools to submit generation requests.
- Do not use the Service to harass anyone or to create content that violates the law or App Store guidelines.
We may suspend or terminate access, and forfeit credits, for accounts that violate these rules.
Our intellectual property
The app, its design, the UNDERGROUND name and logo, part catalogues, reference images, presets, sounds and software are owned by us or our licensors and are protected by intellectual property laws. Apart from the licence to use the app on your Apple devices under Apple's EULA, no rights are granted to you.
Disclaimers
The Service is provided "as is" and "as available". To the fullest extent permitted by law we disclaim all warranties, express or implied, including fitness for a particular purpose, accuracy of generated images, and uninterrupted or error-free operation. AI-generated results may be inaccurate, incomplete or unexpected.
Limitation of liability
To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential or punitive damages, or for loss of data, profits or goodwill, arising from your use of the Service. Our total liability for any claim relating to the Service is limited to the amount you paid us in the twelve months before the claim. Nothing in these Terms limits liability that cannot be limited under applicable law, including your statutory rights as a consumer.
Termination
You may stop using the app at any time by deleting it; subscriptions must be cancelled separately in your Apple ID settings. We may suspend or terminate your access if you breach these Terms or if we discontinue the Service, in which case we will try to give reasonable notice where practical.
Governing law and disputes
These Terms are governed by and construed in accordance with applicable law. UNDERGROUND is offered worldwide, and nothing in these Terms limits the mandatory consumer-protection rights you have under the laws of your country of residence. Where a dispute cannot be resolved with us directly, it will be brought before the courts competent under those laws.
Changes to these Terms
We may update these Terms from time to time. The effective date at the top shows the latest version. Continued use of the app after a change means you accept the updated Terms; if you do not, stop using the app and cancel any subscription.
