ZRO is developed and published by AppHouse, a registered business entity. For App Store compliance purposes:
ZRO stores all your data locally on your device using iOS's built-in UserDefaults system. This includes:

ZRO uses iOS notifications to remind you about your fundamentals. These notifications are handled entirely by Apple's notification system. We schedule them locally on your device at your chosen time. No data is sent to external servers for notifications.
You can delete all your data at any time by:
Since data is stored only on your device, deletion is immediate and permanent.
ZRO does not use any third-party analytics, tracking, or advertising services. Your data never leaves your device.
ZRO does not knowingly collect any data from children. Since we don't collect personal information at all, children can use the app safely.
