ShredMode Privacy Policy

What data ShredMode handles

Core ShredMode data is primarily stored on your device and may include:

• Profile settings used for estimates, such as age, sex, height, weight, body fat, goals, and targets
• Weight, body fat, nutrition, calorie, food, meal, macro, and progress records
• Training activity definitions, sessions, sets, heart-rate zone progress, workout calories, and activity history
• Step data and related activity metrics

Optional connected features may also handle:

• Google account information such as email address and Google user identifier when you connect Google
• Apple account information such as a user identifier and, when Apple provides it, email address or name for Sign in with Apple and related iCloud backup connection
• Google Drive AppData backups containing your ShredMode local database when you enable Drive backup and restore
• iCloud AppData backups containing your ShredMode local database when you enable iCloud backup on iOS
• Food text, food photos, workout details, and relevant profile context when you explicitly use AI estimates
• Diagnostic and crash information used to monitor and improve reliability
• On iOS only, Apple Health data based on the permissions you grant: step count, active energy burned, workouts, and heart-rate samples for reading; and completed live heart-rate workouts that ShredMode records and may save back to Apple Health

How data is used

ShredMode uses data to:

• Operate local calorie, macro, progress, steps, and training features
• Generate calculations and estimates shown to you in the app
• Connect Google only when you choose to use AI estimates or Google Drive backup and restore
• Connect Apple Sign in / iCloud only when you choose optional Apple identity or iCloud backup features
• Create and restore Google Drive or iCloud backups at your direction or while backup is enabled
• Sync steps, import workout and heart-rate context from Apple Health, and avoid double-counting workout calories
• Save live heart-rate workouts you record in ShredMode to Apple Health so they can appear in Health and Fitness history
• Process AI estimate requests that you initiate after granting AI data-sharing consent
• Detect, diagnose, and fix crashes or reliability issues

AI estimates and third-party AI

AI estimates are optional. Before ShredMode sends AI request data off-device, the app asks for explicit AI data-sharing consent. If you allow AI data sharing, ShredMode sends the food text or photo, workout details, and relevant profile context you provide through Quietfield Technologies servers to OpenAI to generate an estimate. AI requests currently require a connected Google account for authentication.

You can revoke AI data-sharing consent inside the app under Account & Data > AI Data Sharing. Revoking consent stops new AI estimate requests until you allow AI data sharing again.

Apple Health

Apple Health access is optional and iOS-only. If you grant permission, ShredMode may:

• Read step count, active energy burned, workouts, and heart-rate samples to sync daily steps, import workout-zone credit, and avoid double-counting workout calories
• Write completed live heart-rate workouts that you start and end in ShredMode, so those workouts can appear in your Apple Health and Fitness history and contribute to activity rings when applicable

ShredMode does not use Apple Health data for advertising, marketing, or data mining. You can change or revoke Health permissions in the iOS Health app or iOS Settings.

ShredMode is not a medical device and does not diagnose, treat, or provide medical advice. It provides user-controlled fitness and nutrition estimates.

Sign in with Apple and iCloud backup

Sign in with Apple is optional. When you use it, Apple may provide a stable user identifier and, when available, an email address or name so ShredMode can associate optional account features on the device.

iCloud backup is optional and iOS-only. When enabled, ShredMode stores app-created backup files using the Apple account on the device (via iCloud Drive / AppData-style storage provided by the platform). ShredMode remains local-first; iCloud and Google Drive backups are user-controlled backup and restore options, not a required cloud account for core tracking.

Third-party services

ShredMode may use these services to provide optional features and reliability functions:

• Google, for optional Google connection and Google Drive AppData backup and restore
• Apple, for optional Sign in with Apple, iCloud backup on iOS, and Apple Health
• OpenAI, through Quietfield Technologies serverless functions, for AI-assisted food and workout analysis that you initiate
• Sentry, for crash reporting and diagnostics. ShredMode limits diagnostics to reliability data, does not send default personal identifiers for advertising, and does not use diagnostics for advertising.

Data sharing and storage

Quietfield Technologies does not operate a general hosted user database for core ShredMode health and fitness data. Most core app data remains on your device unless you enable optional connected features.

When optional connected features are used, some data may be transmitted off-device to perform the requested functionality, such as uploading your local database to Google Drive AppData or iCloud for backup, or processing data you submit for AI analysis. Data transmitted off-device is sent over encrypted HTTPS connections where network transport is used.

Quietfield Technologies does not sell your personal data.

Data retention and deletion

You can delete ShredMode account and app data inside the app under Account & Data > Delete Account & Data. This deletes local ShredMode data on the device and, when Google Drive and/or iCloud backup is connected, app-created cloud backups for those connections. Local backup files you exported yourself remain where you saved them.

You can also disconnect Google or iCloud backup inside the app under Account & Data. Disconnecting a backup service stops new backups for that service on that device but does not by itself delete local app data.

AI data-sharing consent can be revoked in Account & Data > AI Data Sharing.

Apple Health permissions and historical Health records remain under your control in the iOS Health app. Deleting ShredMode app data does not automatically remove workouts or other samples already written to Apple Health; manage those in Health if you want them removed.

To request deletion assistance, email support@quietfieldtechnologies.com with the subject line ShredMode Account Deletion. Quietfield Technologies can delete records under its direct control related to your request and support history, including support correspondence and limited service records where applicable.

Quietfield Technologies may retain limited support and compliance records related to deletion requests for up to 90 days after request completion, unless a longer retention period is required by law.
