Privacy Policy

Last updated: October 24, 2026

Mochi Fit ("the app") stores your workout records on your iPhone and Apple Watch. There is no account. The developer does not operate any server and does not collect your records. Only if you turn on the transfer backup for moving to a new iPhone or reinstalling the app, the app encrypts your records on your device and stores them in Google's Cloud Firestore (neither the developer nor Google can read them; see below).

Information stored on your device

• Your Omochitchi's name
• Workout records (exercise, reps, weight, date and time)
• Hourly step counts
• Settings (counting sensitivity, notification settings, whether reps are read aloud)
• Your transfer code (only if you turn on the transfer backup; stored in the keychain)

This information is kept in storage on your iPhone and Apple Watch that only the app and its widgets can use. It leaves your devices only if you turn on the transfer backup described below.

Transfer backup (only if you turn it on)

If you turn on "Back Up to the Cloud" in the app's Settings, the app encrypts the records above (except your transfer code) on your iPhone and stores them in Cloud Firestore (Firebase), provided by Google LLC, so you can restore them on a new iPhone or after reinstalling the app. It is off by default.

• The key to decrypt them is made only from your transfer code. The transfer code is never sent, so neither the developer nor Google can read the contents
• No name, email address or device identifier is attached to the backup
• Your transfer code is stored in your iPhone's keychain and, if iCloud Keychain is on, synced to your devices with the same Apple ID by Apple
• As with any network connection, Google receives connection information such as your IP address (Firebase privacy and security)
• Turning it off stops sending. You can delete the stored records with "Delete Cloud Records" in Settings. Deleting the app does not delete the cloud records (so you can restore them on a new iPhone)
• If you lose your transfer code, the developer cannot tell which backup is yours

Health

• Read: step count (used for your Omochitchi's stamina)
• Write: workouts counted in the app are saved as workouts (with active energy when recorded on Apple Watch)

The app never uses health data for advertising or marketing and never shares it with third parties. Health data leaves your devices only as step counts inside the encrypted records when you turn on the transfer backup (neither the developer nor Google can read them). You can change permissions at any time in the Health app.

Motion and proximity sensors

To count reps, the app uses the motion sensors of your iPhone and Apple Watch only while you exercise. For push-ups, the iPhone proximity sensor detects when your chest comes close. While you look at its screen, the Apple Watch app uses motion activity and the pedometer (Motion & Fitness) to tell when you start walking and switch its home screen to a step counter. Sensor readings are neither stored nor sent anywhere.

Camera

The app uses your iPhone's front camera only when you choose "Count with the camera". It reads the positions of your joints on the device and uses them only to count your reps. While counting, the video appears on the screen with lines connecting the joints it reads; this is only shown on your screen. No video or photos are saved or sent anywhere. You can change camera access at any time in the iPhone Settings app. If you don't allow it, you can still use the other ways of counting.

Notifications

Notifications about your Omochitchi (hungry, sulking) and workout reminders on days you haven't reached your goal are scheduled on your device. No information is sent anywhere for notifications. You can turn them on or off in Settings.

Sync between iPhone and Apple Watch

Records are exchanged only between your own iPhone and your paired Apple Watch, using Apple's WatchConnectivity. When you choose "Count with Apple Watch", the reps your Apple Watch counts are sent to your iPhone the same way.

Subscription (purchases)

Purchases, renewals and cancellations of the app's monthly plan (new subscribers get the first month free) are handled by Apple's App Store. Payment information such as your card is managed by Apple and never reaches the developer. The app only checks with the App Store on your device whether you're subscribed and when the subscription expires; nothing is sent to any server. The expiry checked on your iPhone is passed to your paired Apple Watch the same way as above (WatchConnectivity). You can review or cancel your subscription in Settings > your name > Subscriptions on your iPhone.

Information we do not collect

• Your name, email address or other contact information (there is no account)
• Location
• Advertising identifiers (IDFA) or any information for tracking
• Usage analytics or crash reports (the app contains no such tools)

If you have turned on "Share With App Developers" in your device settings, Apple may share crash information about the app with the developer.

Deleting your records

Choose "Erase All Records" in the app's Settings to delete all records on your devices (records on Apple Watch are deleted too). Deleting the app also deletes its records on your devices. You can delete the transfer backup with "Delete Cloud Records" in Settings (after "Erase All Records", the backup is emptied too). Workouts saved to Health can be deleted in the Health app.
