+# Phone Recorder - Future Ideas / TODO
+
+## Questions to Address
+
+### Key Rotation
+- What happens when server keypair changes?
+- Current behavior: Old encrypted files can't be decrypted with new key
+- Options:
+  1. Keep old private key archived for decrypting old files
+  2. Sync all files before rotating keys
+  3. Store key version/ID in encrypted file header
+
+### Manual Decryption
+- Document steps to decrypt files copied via USB from phone
+- Need: Python script using server's private key
+- Consider: CLI tool in server/ directory
+
+### No-Key Behavior
+- Current: Deletes recordings if no public key configured (security-first)
+- Alternatives to consider:
+  1. Store unencrypted with warning (less secure)
+  2. Queue recordings until key configured (could fill storage)
+  3. Current behavior is probably correct for security model
+

+
+## Possible Features
+
+### High Priority (if needed)
+- [ ] QR code for key import (avoid email/typing)
+- [ ] Server URL configuration in app UI (currently requires code change for non-defaults)
+- [ ] Manual sync trigger button
+- [ ] View sync history/status in app
+- [ ] **Display last successful sync time on phone** (e.g., "Last sync: 2 hours ago")
+- [ ] **Server status page** - HTML dashboard showing:
+  - When phone last synced
+  - Total recordings count
+  - Recent uploads
+  - Disk space usage
+  - Could be at `/status` or `/dashboard`
+
+### Medium Priority
+- [ ] Configurable recording quality (bitrate, sample rate)
+- [ ] Configurable segment duration (currently 2 hours)
+- [ ] Delete synced files automatically (with configurable retention)
+- [ ] Server: Authentication for upload endpoint
+- [ ] Server: HTTPS with Let's Encrypt
+
+### Audio Analysis & Intelligence
+- [ ] **Speech detection bar** - Visual indicator showing when speech is detected vs silence
+  - Display as additional bar in recording detail view alongside waveform
+  - Data comes from batch processing script
+- [ ] **Sleeping detection** - Detect periods of sleep/silence for overnight recordings
+  - Could help skip to interesting parts
+  - Visual indicator in timeline
+- [ ] **Auto voice recognition / Speaker identification**
+  - Identify who is talking (requires training on voice samples)
+  - Label segments by speaker
+  - Not text-based (transcripts are unreliable)
+- [ ] **Auto highlight generation**
+  - Audio-based detection (not text search since transcripts are bad)
+  - Example: detect phrase patterns like "Ok, note taken" acoustically
+  - Auto-create highlights with tags like "note_taken"
+  - Use audio fingerprinting or keyword spotting models
+
+### Viewer UX
+- [ ] **Background audio playback** - Keep playing current audio while browsing other recordings
+  - Mini player that persists across views
+  - Allows reviewing recordings list while listening
+- [ ] **Highlight duration** - Currently highlights mark only a point; consider adding end time/duration
+- [ ] **Auto-scroll timeline to recordings** - If recordings are only at end of day, auto-scroll so user doesn't have to scroll down to see them
+
+### Low Priority / Nice to Have
+- [ ] Multiple server destinations
+- [ ] Compression before encryption
+- [ ] Resume interrupted uploads
+- [ ] Server: Web UI to browse/play recordings
+- [ ] Server: Transcription integration
+
+### Infrastructure
+- [ ] Systemd service file for server
+- [ ] Docker container for server
+- [ ] NixOS module for server
+- [ ] Backup strategy for server private key
+

+
+## Known Limitations
+
+1. **No streaming encryption**: Entire temp file must complete before encryption
+2. **No partial sync**: If upload fails, whole file retries
+3. **Single server**: Can only sync to one destination at a time
+4. **No authentication**: Anyone who can reach server can upload (relies on encryption for confidentiality)

+
+## Testing Notes
+
+### Unit Tests (server/)
+```bash
+python test_crypto.py
+```
+
+### Integration Tests (server/)
+```bash
+# Start server first
+python main.py &
+python test_integration.py
+```
+
+### Manual Testing Checklist
+- [ ] Record short clip, verify .ogg.enc created
+- [ ] Verify temp file deleted after encryption
+- [ ] Check sync triggers after recording stops
+- [ ] Verify hash verification (corrupt a file, see it retry)
+- [ ] Test LAN detection with different subnets
+- [ ] Test sync mode transitions
