Why CallDo exists

CallDo is designed to ensure you never miss a vital reminder by using real-time phone calls instead of easy-to-ignore notifications. Whether it's for medication, caring for loved ones, or your own critical tasks, our goal is reliability with absolute privacy.

What we collect

Nothing. We do not collect, store, or transmit any of your personal data.

• No personal information (Name, Email, etc.) is required.
• No contact lists are uploaded.
• No audio recordings leave your device.
• No Internet connection is required for the app to function.

What we ask for

To provide reliable "real call" reminders, we ask for specific system permissions:

• Manage Calls: To show the custom incoming call screen.
• Exact Alarms: To trigger reminders at the precise second you set.
• Battery Optimization: To ensure Android doesn't "kill" the reminder service while your phone is asleep.

How we process data

Everything stays on your phone. All scheduling logic, audio processing, and contact association happen strictly within the local CallDo database on your device. We use industry-standard encryption for local storage where applicable, ensuring that even on-device, your data is secure.
