ArchiFit Privacy Policy
Effective date: 2026-11-05
ArchiFit (the "app") helps you log workouts, read InBody result sheets and follow a workout plan. This page explains what information the app handles, where it is kept and what it sends to a server. It is a translation of the Korean policy (/privacy); where the two differ, the Korean one applies.
1. Accounts and identifiers
The app does not create accounts. It does not collect names, email addresses, phone numbers, location or advertising identifiers, and it does not track you across other apps or websites. Requests to the ArchiFit server carry nothing that identifies you. The iPhone app does not collect device identifiers. The Android app includes Google ML Kit, and ML Kit sends a per-installation identifier and device information to Google as listed below.
Google ML Kit in the Android app
The Android app reads the text in InBody sheet photos on your phone with Google ML Kit. The photos and the text read from them are not sent to Google. For diagnostics and usage analytics, ML Kit sends the information below to Google over HTTPS, and it does not transfer this information to third parties. Google's ML Kit data disclosure has the details.
- Device information (manufacturer, model, OS version and build, available ML hardware accelerators)
- App information (package name and app version)
- Per-installation identifiers that are not intended to uniquely identify a user or physical device
- Performance metrics such as latency, API configuration such as image format and resolution, input and output size, feature version, event type and error codes
The iPhone app uses Apple's on-device text recognition and sends none of this.
2. Information kept only on your phone
| Information | Details |
|---|---|
| Workout records | Workout dates, exercises and body parts, weight and reps of each set, rest times |
| Cardio records | Kind (treadmill and so on), time and distance |
| InBody results | Measurement date, sex, height, weight, skeletal muscle mass, body fat percentage, basal metabolic rate and other numbers from the sheet |
| Workout plan | The direction, workouts per week, split and rep scheme you chose |
| Set photos and videos | Photos and videos attached to a set (taken in the app or picked from your photo library). They are copied into the app's folder and never sent to the server |
- InBody sheet photos and PDFs are read on your phone for their text only and deleted right away. The photos are not sent to the server and not kept in the app.
- This information is deleted from your phone when you delete the app. If your phone's backup is on, this information, set photos and videos included, may go into your iCloud backup on iPhone or your Google backup on Android.
3. Information sent to the server (only after you agree to the AI report)
The server (Google Cloud, Seoul region) only writes an answer to the request below and sends it back. It does not store what it receives and does not write it to its logs. The logs keep only numbers such as the kind of request and how long it took.
| When | What is sent | Purpose |
|---|---|---|
| When you open the weekly report after agreeing to the AI report (once a week) | Your workout records from the last 8 weeks (month and day of each workout day, weight and reps of each set by finer body part, the order on that day), what your phone found in those records (body parts kept at the same weight, reps gained at the same weight, rep differences by order and gap, the next weight compared with the plan's reps, records up since the start), and your workout plan (direction, split, workouts per week, rep scheme) | Writing the AI analysis |
- InBody numbers, names, years, cardio records, photos and videos are never sent. The recommended direction and plan, the next-set suggestion and the next workout table are worked out on your phone.
- The app connects to the server to get the list of exercise names. Nothing that identifies you is sent then.
4. Service providers and transfer abroad
The server uses the services of the companies below to write its answers. Personal information is not sold or given to anyone for any purpose other than the ones above.
| Company | Country | What it receives | Purpose | Retention |
|---|---|---|---|---|
| Google LLC (Google Cloud Run) | Republic of Korea (Seoul region) | The requests in section 3 | Running the app's server | Not stored |
| Anthropic PBC (privacy@anthropic.com) | United States | The report request in section 3 | Writing the AI analysis | Deleted within 30 days of receipt (up to 2 years when reviewed for usage policy violations); not used for AI training |
Every company above receives only what this section lists, uses it only to provide its service to ArchiFit, and protects it at the same or an equal level as this policy, the App Store Review Guidelines and the Google Play User Data policy require.
The transfer abroad happens when you open the report, through the ArchiFit server (Seoul) over an encrypted connection (HTTPS). Your consent is asked the first time you open the report. If you decline, or later turn off the AI report in Settings, nothing is sent (turning it off also deletes the AI analysis kept on your phone). The report and every other feature of the app still work.
5. Retention and deletion
- Information on your phone: kept until you delete it in the app or delete the app.
- The server: stores nothing, so there is nothing to delete.
- The companies in section 4: each deletes the information when its retention period ends.
6. Your rights
- You can edit or delete your workout records and InBody results in the app. Settings → Delete all records deletes everything at once, and deleting the app deletes everything.
- Nothing is left on the server, so there is no information to request access to or deletion of. For any question, use the contact below.
7. Security
- All communication with the server is encrypted with HTTPS.
- The server does not store what it receives and does not write it to its logs.
- The app's information is protected by your phone's operating system storage protection for apps.
8. Children
The app is not intended for children under 14.
9. Medical disclaimer
The app's guidance and sentences are general fitness information and not a medical diagnosis, treatment or prescription. If you feel pain, stop exercising and consult a medical professional.
10. Changes
When this policy changes, the app and this page will say so.
