Juice ("the app") is a personal fuel and EV-charging log for iPhone, published by Luboš Bury ("we", "us"). By using the app you agree to these terms. If you do not agree, please do not use 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.
Juice Pro is available as:
Prices are shown in the app at the point of purchase in your local currency. Purchases are billed to your Apple ID.
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.
Lifetime means for the lifetime of the app and its service — not the purchaser's lifetime. See section 4.
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.
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:
The core on-device app — logging, statistics, insights, import/export — does not depend on the cloud service and continues to work.
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. See the Privacy Policy for details.
Use the app for your own personal record-keeping. Do not attempt to disrupt the service, reverse-engineer paid entitlements, or misuse the cloud infrastructure.
The app is provided "as is", 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 or consequential damages arising from use of the app.
We may update these terms as the app evolves. Material changes will be reflected here with a new "last updated" date.
