Thank you for your interest in Hatchiko. This Privacy Policy outlines how we handle your data and privacy when using the app, demonstrating our commitment to transparency, respect for users, and responsible data practices.

About Hatchiko

Hatchiko is a virtual pet experience inspired by classic Tamagotchis, reimagined for the Apple Watch. Users can feed, play with, and help their pet evolve — but with a unique twist: Hatchiko connects to your Apple Health data (sleep and exercise) to reflect your own healthy habits in your pet’s well-being.

• When you sleep using Sleep Mode, your pet also rests.
• When you exercise, your pet becomes happier and healthier.

It’s a fun, nostalgic, and engaging way to encourage better daily habits.

About the Developer

Hatchiko was entirely designed and developed by Luan Aiezza, an independent developer focused on creating creative, emotionally engaging, and well-being-oriented apps.

1. Data Collection

Hatchiko does not collect, store, share, or transmit any personally identifiable data.

The app uses data from the Apple HealthKit framework only with your explicit permission, and only locally. Specifically:

• Sleep Mode and Exercise Activity are accessed to reflect your habits in the pet’s behavior.
• No health data is sent to any server, stored externally, or shared with third parties.

2. Local Storage and Health Data Use
