Juice is built to be private by default. This policy explains what the app stores, when anything leaves your device, and your rights over your data.
Data controller. The controller responsible for any personal data processed through Juice is Luboš Bury, Czech Republic, contactable at [email protected].
Everything you log — fuel-ups, charges, expenses, vehicles, receipts — is stored on your device. You can use the entire app, including statistics and insights, without an account and without any data ever leaving your iPhone.
If you have Juice Pro and sign in (Sign in with Apple or Google), you can enable cloud backup and sync. Then, and only then, your logged data leaves your device to sync across your devices.
Where the GDPR applies, we process personal data on these legal bases:
We keep third parties to a minimum and do not use advertising or analytics SDKs:
Your synced content is stored in the EU. Sign-in and purchase providers may process limited account data under their own policies.
Receipt text recognition runs on-device (Apple Vision / on-device intelligence). Receipt photos are not uploaded for processing.
Data in transit is protected with TLS (HTTPS). Cloud-stored data is held by Supabase with access restricted to your authenticated account. No method of storage or transmission is 100% secure, but we take reasonable measures to protect your data.
Cloud data is retained while your account is active. When you delete data or your account, we remove the corresponding cloud-stored data; short-lived backups may persist for a limited period before being overwritten. On-device data is removed when you delete entries or uninstall the app.
Where the GDPR applies, you have the right to access, rectify, erase, restrict, or object to processing of your personal data, and the right to data portability and to withdraw consent at any time. To exercise these rights, contact [email protected].
You also have the right to lodge a complaint with a supervisory authority. In the Czech Republic this is the Office for Personal Data Protection (Úřad pro ochranu osobních údajů), uoou.gov.cz.
Juice is not directed to children. You must be at least 16 years old (or the minimum age of digital consent in your country) to create an account or enable cloud sync.
The Juice website (juicelog.com) is a static site. It sets no cookies and uses no analytics or tracking.
We may update this policy as the app evolves; material changes will be reflected here with a new "last updated" date.
