LifterOS is a fitness data app for organizing training logs, cardio, body composition, progress photos, sleep, nutrition, bloodwork, protocols, imports, and related notes. This policy explains what information LifterOS handles, how it is used, and what choices you have.

LifterOS is designed to be local-first. Most data you enter, import, or sync stays on your device unless you choose a feature that uploads data, such as LifterOS Cloud, ChatGPT integration, TestFlight feedback, or the beta sign-up form on the LifterOS website.

Information LifterOS Handles

Depending on the features you use, LifterOS may handle:

• Account information, including Sign in with Apple identifiers and any name or email address Apple provides.
• Beta sign-up and support information, including your name, email address, interest in LifterOS, phone or iOS version, and messages you choose to submit.
• Fitness data, including strength workouts, cardio activity, workout templates, folders, sets, reps, loads, distances, times, training notes, and activity history.
• Body and health data, including body weight, body composition, DEXA or InBody-style records, sleep, nutrition, bloodwork, supplements, medications, protocols, and related measurements.
• Imported content, including PDFs, CSV files, images, extracted values, source records, review sessions, normalized metrics, and observations created from imports.
• Photos or videos, if you use progress-photo features.
• User content, including manual entries, notes, custom protocol names, custom exercise names, and other details you choose to save.
• LifterOS Cloud and ChatGPT integration data, including cloud export status, link codes, proposed drafts, save or reject actions, and authentication state.
• App diagnostics that may be available through TestFlight, Apple crash reporting, or privacy-safe app logging.

Apple Health

If you grant Apple Health permissions, LifterOS uses only the categories you approve. Current Apple Health workflows may include body composition, sleep, nutrition, and other user-approved fitness or health signals. You can change Apple Health permissions at any time in iOS Settings. LifterOS does not use Apple Health data for advertising or tracking.

How LifterOS Uses Information

LifterOS uses information to:

• Save, normalize, and display your fitness, health, nutrition, protocol, import, and progress history.
• Consolidate related fitness data into a standardized record that can be reviewed across workouts, recovery, body composition, bloodwork, protocols, and progress photos.
• Generate trends, summaries, charts, and personal analysis inside the app.
• Support optional ChatGPT analysis and draft creation when you choose to upload data and link ChatGPT.
• Maintain account access, authentication, beta access, security, and support.
• Improve reliability and investigate crashes or defects without intentionally logging private health payloads.

LifterOS does not sell your personal information. LifterOS does not track you across apps or websites for advertising.

Local Data, LifterOS Cloud, and ChatGPT

Most LifterOS data is stored locally on your device. Local data remains on your device unless you delete it, uninstall the app, sync it through Apple Health, or choose a feature that uploads data.

LifterOS Cloud and ChatGPT integration are optional. If you use them:

• You sign in with Apple before uploading app data.
• Uploads occur only after an explicit upload action in LifterOS.
• Uploaded data is associated with your LifterOS Cloud account.
• ChatGPT may use uploaded LifterOS data to answer questions, analyze trends, and propose new records or drafts.
• ChatGPT-created drafts are proposals until you review and approve them in LifterOS.
• Rejecting a draft prevents that draft from being saved into your local app data.

Disconnecting or signing out of LifterOS Cloud on a device stops that device from using the current cloud session, but it may not automatically delete data that was already uploaded. If you have used LifterOS Cloud or ChatGPT integration and want to ensure all cloud-linked data is deleted, email info@lifter-os.com.

Sharing and Service Providers

LifterOS may use service providers to operate app features, authentication, cloud storage, beta distribution, website forms, support, and ChatGPT integration. These may include Apple services, TestFlight, WordPress.com or Jetpack for website forms, cloud infrastructure providers, and OpenAI services when you choose to use ChatGPT features.

LifterOS shares information only as needed to provide the features you use, comply with law, protect users and the service, investigate issues, or act with your direction.

Retention and Deletion

Local app data remains on your device until you delete records, delete imports, uninstall the app, or otherwise remove the data using iOS or LifterOS controls.

Cloud data may be retained while your LifterOS Cloud account or ChatGPT link is active, or as needed to operate beta features, investigate issues, prevent abuse, and comply with legal obligations.

Deleting local records does not necessarily delete earlier cloud uploads until you upload updated data or request cloud deletion. To ensure all LifterOS Cloud, ChatGPT-link, beta support, or website form data associated with you is reviewed for deletion, email info@lifter-os.com. This is the recommended deletion path if you have ever uploaded data, linked ChatGPT, joined the beta, or contacted support.

Some records may be retained when required by law, security needs, abuse prevention, backup retention windows, or legitimate operational obligations.

Security

LifterOS uses platform security features such as iOS app sandboxing and Keychain storage for cloud authentication tokens. Cloud features use encrypted network connections. No app or service can guarantee perfect security, so you should use LifterOS only with data you are comfortable storing in a personal fitness and health-tracking app.

Medical and Fitness Disclaimer

LifterOS organizes health, fitness, nutrition, lab, protocol, and progress data for personal tracking and analysis. LifterOS does not diagnose, treat, prescribe, or replace advice from qualified medical professionals.

Your Choices

You can:

• Choose what to enter, import, sync, or upload into LifterOS.
• Approve or deny Apple Health permissions in iOS Settings.
• Use LifterOS without connecting LifterOS Cloud or ChatGPT.
• Sign out of LifterOS Cloud in the app.
• Review, approve, or reject ChatGPT-created drafts before they are saved.
• Delete local records, imports, and progress photos in the app where delete controls are available.
• Email info@lifter-os.com to request deletion of cloud-linked data, beta sign-up data, or support messages associated with you.

Children

LifterOS is not intended for children under 13. Do not use LifterOS if you are under 13.

Changes to This Policy

This policy may be updated as LifterOS changes. The effective date above will be updated when material changes are made.
