Terms of Use (EULA)

Last updated: 9 July 2026

Juice ("the app") is a personal fuel and EV-charging log for iPhone, published by Luboš Bury ("we", "us"), an individual developer based in the Czech Republic. This End User License Agreement ("Agreement") is a legal agreement between you and us. By downloading or using the app you agree to these terms. If you do not agree, do not use the app.

1. The app

Juice lets you log fuel-ups and charges, import history, view statistics and insights, and — with a Juice Pro subscription or the Lifetime purchase — track multiple vehicles and back up your data to the cloud. The app works fully offline; a network connection is only needed for optional cloud sync.

You must be at least 16 years old (or the minimum age of digital consent in your country) to use the app.

2. Juice Pro — subscriptions and one-time purchase

Juice Pro is available as:

• Monthly and Yearly auto-renewable subscriptions. The Yearly plan starts with a 14-day free trial for new subscribers.
• A one-time Lifetime purchase.

Prices are shown in the app at the point of purchase in your local currency. All purchases are processed by Apple and billed to your Apple ID; Apple is the merchant of record.

Auto-renewal. Subscriptions renew automatically at the end of each period unless cancelled at least 24 hours before the period ends. You can manage or cancel a subscription anytime in your device's Settings → Apple ID → Subscriptions. If you cancel, Pro features remain available until the end of the paid period. If a free trial is not cancelled before it ends, it converts to a paid Yearly subscription.

Refunds are handled by Apple in accordance with the Apple Media Services Terms and Conditions. Where you are an EU/EEA consumer, statutory rights (including any right of withdrawal for digital content, to the extent applicable and not waived at purchase) are unaffected by this Agreement.

Lifetime means for the lifetime of the app and its service — not the purchaser's lifetime. See section 4.

3. Free tier and vehicle limits

Without Juice Pro, the app is fully usable for one active vehicle, entirely on-device. Juice Pro raises the active-vehicle limit to 50 vehicles — described as "unlimited" in marketing, but capped at 50 for performance and stability. Vehicles beyond your tier's limit are moved to a read-only archive; their data is never deleted, and reducing or upgrading your plan never erases anything.

4. Cloud service may change or end

Cloud backup and sync are provided on a best-effort basis. If the ongoing cost of operating the cloud service materially exceeds the revenue from Juice Pro, we may discontinue the cloud service with reasonable advance notice. In that event:

• Your data on your device is unaffected and remains fully usable and exportable.
• No refunds are owed for the discontinuation of an optional cloud feature, though we will handle any active subscriptions fairly and in line with App Store policy.

The core on-device app — logging, statistics, insights, import/export — does not depend on the cloud service and continues to work.

5. Your data

Your logs belong to you. Local data stays on your device. When you sign in and enable cloud sync (Pro), your data is stored with our cloud provider solely to sync it across your devices. Our handling of personal data is described in the Privacy Policy.

6. Acceptable use and termination

Use the app for your own personal record-keeping. Do not attempt to disrupt the service, reverse-engineer paid entitlements, circumvent purchase mechanisms, or misuse the cloud infrastructure. We may suspend or terminate access to the optional cloud service if you materially breach these terms; your on-device data remains yours and unaffected.

7. App Store and Apple

This Agreement is between you and us only, not with Apple. Apple is not responsible for the app or its content. The following terms apply to your use of the app obtained from the Apple App Store:

• Scope of license. Your license is non-transferable and limited to use of the app on any Apple-branded products that you own or control, as permitted by the App Store Usage Rules in the Apple Media Services Terms and Conditions.
• Maintenance and support. We are solely responsible for providing any maintenance and support for the app. Apple has no obligation to furnish any maintenance or support services.
• Warranty. We are solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) of the app to you; to the maximum extent permitted by applicable law, Apple will have no other warranty obligation with respect to the app.
• Product claims. We, not Apple, are responsible for addressing any claims relating to the app or your use of it, including (i) product liability claims; (ii) any claim that the app fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy, or similar legislation.
• Intellectual property. In the event of any third-party claim that the app or your use of it infringes that third party's intellectual property rights, we (not Apple) will be responsible for the investigation, defense, settlement, and discharge of such claim.
• Legal compliance. You represent and warrant that you are not located in a country subject to a U.S. Government embargo or designated as "terrorist-supporting," and that you are not listed on any U.S. Government list of prohibited or restricted parties.
• Third-party terms. You must comply with any applicable third-party terms of agreement when using the app.
• Third-party beneficiary. Apple and Apple's subsidiaries are third-party beneficiaries of this Agreement and, upon your acceptance of it, will have the right (and will be deemed to have accepted the right) to enforce this Agreement against you as a third-party beneficiary.

8. No warranty; limitation of liability

Except as expressly stated above and to the fullest extent permitted by applicable law, the app is provided "as is" and "as available", without warranties of any kind. Statistics and insights are informational estimates, not financial or engineering advice. To the fullest extent permitted by law, we are not liable for any indirect, incidental, or consequential damages arising from use of the app. Nothing in this Agreement limits liability that cannot be limited under applicable law, including your mandatory statutory consumer rights.

9. Governing law

This Agreement is governed by the laws of the Czech Republic, without prejudice to any mandatory consumer-protection rules of the country in which you are habitually resident. Nothing here deprives you of the protection afforded by provisions that cannot be derogated from by agreement under the law of your country of residence.

10. Severability

If any provision of this Agreement is held unenforceable, the remaining provisions remain in full force and effect.

11. Changes

We may update these terms as the app evolves. Material changes will be reflected here with a new "last updated" date.
