Privacy Policy
Last updated: March 8, 2026
This Privacy Policy explains how Koi ("we", "our", or "the App") handles information within the app. We are committed to respecting your privacy.
Information Stored on Your Device
Koi does not collect your data. The app only stores the information you choose to enter locally on your device:
- Your name and birthday (optional) to personalize your experience
- The habits you create, track, and complete, along with your goals and progress
- Journal entries you write within the app
- Images and voice notes you choose to add to reflections and goal journals
- Records of meditation, breathing exercises, and timer sessions you complete
- Your notification settings, sound, and haptic feedback preferences
Data Storage
All your data is stored locally on your device. Koi does not transmit your personal information to any external servers. Your data remains on your device unless you choose to back it up using your device's backup services (such as iCloud or Google Cloud).
No Analytics or Tracking
Koi does not use any analytics services, advertising networks, or third-party tracking tools. We do not use third-party analytics or advertising trackers. The app functions entirely offline.
Permissions
Koi requests the following device permissions:
- To send you habit reminders, goal reminders, and daily check-in notifications at times you choose
- To provide haptic feedback when you interact with the app (can be disabled in settings)
- To let you take and attach photos in reflections and goal journals
- To let you record and attach voice notes in reflections and goal journals
- To let you select and attach existing images from your photo library in reflections and goal journals
- To calculate local sunrise and sunset times for Koi's Solar Time features
Camera, microphone, and photo library access are optional and only used when you choose to create or attach media in the app.
Location Data
Koi may request access to your device's location to power the Solar Time feature, which calculates local sunrise and sunset times and uses them to shape your in-app experience.
- Your approximate geographic coordinates (latitude and longitude), accessed only while the app is in use
- Solely to compute sun position and local solar times on your device
- All location calculations happen entirely on-device. Your location is never sent to our servers, stored remotely, or shared with any third party
- You can withdraw location permission at any time in your device's Settings under Privacy & Security → Location Services → Koi. If you decline or revoke this permission, Solar Time features may be unavailable or fall back to a default experience
Data Sharing
We do not sell, rent, or share your personal information with any third parties. Since all data is stored locally on your device, we do not have access to it.
Your Control
You have full control over your data:
- Edit or delete individual habits, goals, and reflections at any time
- Disable notifications globally or for specific habits and goals
- Toggle sound effects and haptic feedback in settings
- Uninstalling the app will permanently delete all locally stored data
Children's Privacy
Koi is not directed at children under 13. Because Koi does not collect personal information, we do not receive personal information from children.
Changes
We may update this policy from time to time. If changes are significant, we will update the "Last updated" date above.
