Keys for All - Complete Feature Documentation

Overview

"Keys for All" is VoiceUwu's innovative monetization system where users purchase keys to unlock individual features. Each key costs $3 and unlocks one feature permanently. Users can purchase keys individually or in bulk packs with discounts, and share keys with the community.

Core Philosophy

The Keys for All system is built on these principles:

1. Core functionality remains free - Basic voice analysis is always available
2. Pay for what you use - Each feature costs 1 key ($3)
3. Community distribution - Users can share and donate keys to others
4. No user tracking - Anonymous, local validation preserves privacy
5. Transparent pricing - Simple 1 key = 1 feature model

How It Works

Free Features (No Keys Required)

• Core voice pitch tracking
• Basic visualization
• Standard haptic feedback
• Access to feature marketplace
• 1 vote for feature requests

Paid Features (1 Key Each)

Users can unlock any feature for 1 key ($3):

• Advanced monitors and analysis tools
• Premium visualizations
• Export and reporting features
• UI customization options
• Enhanced haptic patterns
• Professional tools

Key Purchasing Options

• Individual Keys: $3 each
• 5-Key Pack: $15 (includes 1 bonus key)
• 10-Key Pack: $30 (includes 1 bonus + 3 community keys)
• Bulk Packs: Larger packs with increasing discounts

Key Format and Validation

Key Structure

VUUW-XXXX-XXXX-XXXX

• VUUW: Product identifier
• XXXX-XXXX-XXXX: 12-character alphanumeric code
• Each key unlocks one feature permanently

Validation Process

1. Local Validation: Keys are validated using a cryptographic algorithm locally
2. No Network Required: Works offline, no server calls needed
3. Instant Activation: Feature unlocks immediately upon key entry
4. Persistent Storage: Validated keys stored securely in UserDefaults
5. Feature Binding: Each key is bound to a specific feature

Technical Implementation

Key Generation Algorithm

// Pseudo-code for key generation
func generateKey(level: LicenseLevel, batch: String?) -> String {
    let segments = [
        "VUUW",
        generateSegment(4),
        generateSegment(4),
        generateSegment(4),
        level.identifier // "L1" or "L2"
    ]
    
    let key = segments.joined(separator: "-")
    let checksum = calculateChecksum(key)
    
    return embedChecksum(key, checksum)
}

Validation System

// Key validation structure
struct LicenseValidator {
    static func validate(_ key: String) -> ValidationResult {
        // 1. Format validation
        guard isValidFormat(key) else {
            return .invalid(.formatError)
        }
        
        // 2. Checksum validation
        guard isValidChecksum(key) else {
            return .invalid(.checksumError)
        }
        
        // 3. Level extraction
        let level = extractLevel(key)
        
        // 4. Store validated key
        if case .valid(let license) = result {
            LicenseManager.shared.store(license)
        }
        
        return .valid(License(key: key, level: level))
    }
}

Storage and Persistence

// License storage in UserDefaults
extension UserDefaults {
    private static let licenseKey = "com.voiceuwu.license"
    private static let keyInventoryKey = "com.voiceuwu.keyInventory"
    
    var currentLicense: License? {
        get { 
            guard let data = data(forKey: Self.licenseKey) else { return nil }
            return try? JSONDecoder().decode(License.self, from: data)
        }
        set {
            let data = try? JSONEncoder().encode(newValue)
            set(data, forKey: Self.licenseKey)
        }
    }
    
    var keyInventory: [String] {
        get { array(forKey: Self.keyInventoryKey) as? [String] ?? [] }
        set { set(newValue, forKey: Self.keyInventoryKey) }
    }
}
