Frequently Asked Questions
How do reminders and Live Activities work?
OlcSub uses native iOS local notifications and Live Activities to help you meet your daily hydration goal. Make sure notifications and Live Activities are enabled in your iOS Settings (Settings → OlcSub → Notifications & Live Activities).
Where is my hydration data stored?
Your data is stored 100% locally on your iPhone. We do not require any accounts, and we do not sync or upload your water intake records to external servers.
Are there any paid subscriptions?
No. OlcSub is a clean, distraction-free app without hidden recurring subscriptions.

In compliance with Apple App Store Review Guidelines, you have complete control over your on-device data:
