Nice

Product Introduction

1. Definition: Nice is an iOS-native sexual wellness tracker application (technical category: mobile health app) that operates exclusively on iPhone and iPad devices. It functions as a private digital journal for intimate activities without cloud synchronization or data collection.
2. Core Value Proposition: It exists to provide users with a secure, offline method to analyze sexual health patterns and relationship dynamics while guaranteeing end-to-end encryption and zero data sharing—addressing critical privacy concerns in sensitive health tracking.

Main Features

1. Activity Tracking: Logs encounters with customizable parameters (date, duration, protection use, partner(s)) and supports custom activities with unique icons/emojis. Data is stored in an encrypted SQLite database on-device.
2. Partner Management: Records partner details (name, photo, STD/STI status) using Core Data for local storage. Integrates with iOS Contacts for optional linking.
3. HealthKit Sync: Optional one-way integration with Apple Health via HealthKit API. Writes activity data to HealthKit but only modifies Nice-originated entries.
4. Encrypted Backups: Generates password-protected .nice files via iOS Document Picker. Restores via local storage or iCloud Drive without server dependency.
5. Biometric Security: Implements Apple’s Local Authentication framework for Touch ID/Face ID locking, with 256-bit AES encryption for all stored data.
6. Geotagging: Uses Core Location to map encounters via MapKit, with coordinates encrypted and never off-device.

Problems Solved

1. Pain Point: Traditional sexual health apps compromise privacy by storing sensitive data on external servers. Nice eliminates this risk via offline operation and device-exclusive encryption.
2. Target Audience:
   • Privacy-focused individuals tracking personal health metrics.
   • Couples using shared iCloud accounts for synchronized logging.
   • Polyamorous communities requiring multi-partner tracking.
   • Healthcare patients monitoring STD/STI history or fertility.
3. Use Cases:
   • Tracking contraceptive efficacy across partners.
   • Correlating mood changes with sexual activity frequency.
   • Auditing STD test dates for medical consultations.
   • Analyzing location-based encounter patterns privately.

Unique Advantages

1. Differentiation vs. Competitors: Unlike server-dependent apps (e.g., Coral), Nice requires no accounts, collects zero analytics, and rejects third-party SDKs. Competitors monetize via data; Nice uses a one-time purchase model.
2. Key Innovation: Hybrid privacy architecture—combining iOS-native encryption (Data Protection API) with optional iCloud sync. Users control data flow: fully local or encrypted Apple ecosystem-only.

Frequently Asked Questions (FAQ)

1. How does Nice ensure my sexual activity data remains private?
   All data is encrypted on-device using AES-256 and never transmitted to servers. Backups require manual export and password decryption.
2. Can Nice sync with Apple Health for comprehensive health tracking?
   Yes, via opt-in HealthKit integration. Nice writes activity duration/date to Health but only accesses its own entries.
3. What happens to my Nice data if I switch iPhones?
   Data transfers require manual iCloud backup (system-level) or .nice file export/import. No automated sync exists to prevent unintended data exposure.
4. Does Nice support tracking for non-monogamous relationships?
   Yes, unlimited partner entries with custom details (STD status, names, photos) are supported locally.
5. How do I recover data if my device is lost?
   Restore from a pre-exported .nice backup file stored in iCloud Drive or locally. Without a backup, data is irrecoverable due to zero server storage.
