## 2. Getting Started
**Q4. Do I need an account?**
No. The app silently creates a sign-in. This creates a stable UID for your device/app install — not linked to your name, phone number, or email.
**Q5. How do I post a ping?**
1. Type your message (max 500 characters).
2. Or use **voice input** (tap the mic button).
3. Choose a category: ⚠️ Alert, ℹ️ Info, 💬 Social, 🆘 Help, or 🛍️ Market (for local products or services).
4. Set how long it stays (1–24 hours).
5. Select your visibility radius (500m → 10km).
6. Tap **Send.**
If you’re offline, you’ll see a **banner**:
> “🚫 No Network Available. You can still create a ping; it will be sent when network is restored.”
**Q6. What is the default message duration (TTL)?**
Default TTL = **1 hour.** You can choose up to 24 hours.
**Q7. Can I reply to a ping?**
Yes! Tap any visible ping → choose **Reply** → type or dictate your message.
Replies expire automatically when the parent ping expires.

## 4. Privacy & Safety
**Q12. Do you store messages permanently?**
No. All pings and replies expire automatically.
Unsent (offline) messages stay on your device until delivered.
**Q13. What personal data do you collect?**
mortalpings uses only:
- UID & displayId
- Approximate location (for radius)
- Message text (temporary)
- Basic device info
No names, phone numbers, emails, photos, or contact lists.
**Q14. What about voice input privacy?**
Voice processing happens locally — your audio is never uploaded or stored.
Voice mode is helpful when you can’t type — for instance, **while driving or eating.**
**Q15. What if someone abuses mortalpings?**
Use the in-app Report option. Reports include:
- messageId/replyId
- the reported item’s sender or displayId
- the reporter’s UID (reportedByUid) — this is required so reports cannot be forged
Moderation actions: warning, mute, suspend, or permanent ban of the offending UID. Bans prevent future writes from that UID
