fix: L1 privacy manifest, L2 privacy policy, M3-M5 code quality, version/icon confirmed

L1: Add PrivacyInfo.xcprivacy declaring UserDefaults (CA92.1), FileTimestamp (C617.1),
    DiskSpace (E174.1); register in Xcode project Copy Bundle Resources phase.

L2: Add PRIVACY.md - self-hosted server model, no third-party data collection.

L6: Version 1.0.0+1 already set in pubspec.yaml (confirmed).

L7: App icon sizes verified - all required sizes present, no alpha channel.

M3: Extract NavigateNotifier to lib/services/navigate_notifier.dart; replace
    mutable static instance with navigateNotifierProvider (Riverpod StateProvider).

M4: Replace O(n log n) Set eviction in _seenSeqs with O(1) FIFO List+Set pair.

M5: Register com.mnsoft.pailot/backup MethodChannel in SceneDelegate; call
    NSURLIsExcludedFromBackupKey on messages directory at first init.

+# Privacy Policy for PAILot
2
+
3
+**Last updated: April 1, 2026**
4
+
5
+## Overview
6
+
7
+PAILot is a voice-first AI communication client that connects to your own self-hosted AIBroker server. This privacy policy explains how PAILot handles your data.
8
+
9
+## Data Collection and Use
10
+
11
+**PAILot does not collect, transmit, or share your data with any third party.** The app communicates exclusively with your own AIBroker server, which you host and control.
12
+
13
+### What PAILot Accesses
14
+
15
+**Microphone**
16
+PAILot requests microphone access to record voice messages. Recorded audio is transmitted only to your own AIBroker server. No audio is sent to any third-party service.
17
+
18
+**Camera and Photo Library**
19
+PAILot requests camera and photo library access to allow you to attach images to messages. Images are transmitted only to your own AIBroker server.
20
+
21
+**Local Network**
22
+PAILot uses Bonjour/mDNS (via the local network) to discover your AIBroker server on the local network. No network scanning data is transmitted outside your local network.
23
+
24
+**Push Notifications**
25
+PAILot uses Apple Push Notification service (APNs) to receive notifications when messages arrive while the app is in the background. Your device token is transmitted only to your own AIBroker server, which uses it to send notifications via APNs on your behalf. The device token is not shared with any third party.
26
+
27
+### What PAILot Stores Locally
28
+
29
+**Messages**
30
+Conversation messages are stored locally on your device in the app's Documents directory. This includes text content and image attachments you have received or sent. Audio messages are stored as temporary files and cleaned up after playback.
31
+
32
+**Settings and Preferences**
33
+Connection settings (server address, port, authentication token) and app preferences are stored in the iOS Keychain (for the authentication token) and UserDefaults (for other settings).
34
+
35
+**No Analytics or Tracking**
36
+PAILot contains no analytics SDKs, no tracking libraries, no advertising SDKs, and no crash-reporting services that transmit data to third parties.
37
+
38
+## iCloud Backup
39
+
40
+Message data stored in the Documents directory may be included in iCloud backups if iCloud Backup is enabled on your device. This data is encrypted by Apple as part of the standard iCloud Backup encryption. You can disable iCloud Backup for PAILot in iOS Settings.
41
+
42
+## Data Sharing
43
+
44
+PAILot does not share any data with third parties. All communication is between your device and your own self-hosted AIBroker server.
45
+
46
+## Your Control
47
+
48
+Because all data is stored locally on your device or on your own server, you have full control:
49
+- Delete the app to remove all locally stored data
50
+- Manage your AIBroker server to control server-side data
51
+- Use iOS Settings to revoke microphone, camera, or notification permissions at any time
52
+
53
+## Children's Privacy
54
+
55
+PAILot is not directed at children under 13 and does not knowingly collect information from children.
56
+
57
+## Changes to This Policy
58
+
59
+If this policy changes in a meaningful way, the updated date at the top of this document will reflect the change.
60
+
61
+## Contact
62
+
63
+PAILot is a personal tool. For questions, contact the developer directly through the App Store listing.
