Callback Reminder

Never miss returning a call again. Callback Reminder detects every missed or
rejected call and instantly shows a popup on your lock screen — just tap when
you want to call back, and a reminder is created in your Google Calendar.

⚡ HOW IT WORKS
1. You miss a call or decline one
2. A popup appears on your lock screen
3. Tap a time — 30 min, 1 hr, 2 hrs, this evening (7 PM), or tomorrow morning
4. A calendar event with a reminder is created in your chosen calendar
5. You get notified and remember to call back

If you don't pick a time, the app automatically schedules a reminder for you
after your chosen default delay. No taps needed.

📅 CALENDAR INTEGRATION
Reminders are created directly in your Google Calendar. Pick any calendar you
have linked on your phone. If you have Google Calendar sync turned on, your
reminders will appear across all your devices automatically.

🔒 STAYS ON TOP OF YOUR CALLS
• Lock-screen popup — the reminder prompt appears even if your phone is locked
• Dual-SIM support — monitors calls on both SIMs
• Reliable background service — keeps working even after a reboot
• Battery friendly — efficient call monitoring that won't drain your battery

🎯 FILTER WHAT MATTERS
• Contacts-only mode — only create reminders for people in your contacts
• Spam filter — skip unknown callers and numbers you've blocked
• Exclusion list — add numbers you never want reminders for

🆓 COMPLETELY FREE
No ads. No in-app purchases. No subscriptions. Just a simple tool that works.

🔐 PRIVACY FIRST
Your personal data stays on your device — call logs, phone numbers, contacts,
and calendar events are never sent to external servers. We do not collect or
store your personal information. The app uses Firebase Crashlytics for crash
reporting, handled under Google's privacy policy. No accounts to create.

📲 WHAT THE APP NEEDS
The app requests a few permissions — all for the reminder feature:
• Phone state — to detect missed calls
• Contacts — to show the caller's name
• Calendar — to create reminder events
• Display over lock screen — to show the instant popup
