Privacy Policy — Fit for Two

Last updated: 2026-10-30

Fit for Two™ ("Fit for Two", "we", "us") is a fitness app made by Babbling Comet for you and one other person — a partner or workout buddy — to train together. This policy explains, in plain language, what the app does and does not do with your information.

Short version

We don't run a server. Nothing you enter leaves your iPhone except what you choose to share with your partner through Apple's iCloud, and what you choose to save to Apple Health or Apple Calendar. We do not sell your data, show you ads, track you across other apps, or share anything with third parties for advertising, analytics, or any other purpose.

What the app stores on your device

The app stores the following on your iPhone, using Apple's SwiftData local database:

Your name and the avatar photo you pick (or take with the camera).
Your age, biological sex (optional), height, body weight, fitness level, priorities, available equipment, and the days per week you want to train.
Your workout plan, completed workouts (date, exercises, sets, reps, weights), weight log entries, and any personal records the app detects.
Your reminder preferences, your choice of relationship type (partners or friends), and your preference about whether to see the "spicy" prompt variant.

This data stays on your device unless you explicitly turn on one of the integrations below.

Apple Health

If you allow it, the app reads the following from Apple Health to pre-fill your profile and show weight-trend charts:

Body weight (bodyMass)
Height (height)
Body mass index (bodyMassIndex)
Date of birth
Biological sex

If you allow it, the app writes the following to Apple Health so your activity rings reflect what you did in Fit for Two:

Completed workouts (HKWorkout) — kind, start/end time
Active energy burned (activeEnergyBurned) estimated from the workout

You can grant or revoke any of these permissions at any time in Settings → Health → Data Access & Devices → Fit for Two. The app does not use any of this information for advertising, does not share it with third parties, and does not send it to any Fit for Two or Babbling Comet server (there isn't one).

Apple Calendar

If you turn on Settings → Add to Apple Calendar, the app writes your upcoming workout events to a calendar you choose. Nothing is read from your other calendars. You can revoke access at any time in iOS Settings.

iCloud and partner sharing

To share progress with your partner, Fit for Two uses Apple's CloudKit service under your own iCloud account:

Your private workout data is not uploaded. We never put your SwiftData database into the cloud.
When you create or accept a partner invitation, Fit for Two creates a small "shared zone" inside your iCloud container. Only the two of you — the two Apple IDs on the share — can read it. Apple cannot read it either (CloudKit encrypts shared data).
Into that shared zone, Fit for Two writes a lightweight profile summary of you (your display name, chosen accent color, avatar photo, days per week, and whether you've designated the pairing as "Partners" or "Friends") and a workout summary for each completed workout (session title, kind, date, duration, any personal records). It does not write your full workout plan, your weight history, or anything you didn't finish.
You can leave or end the share at any time from Settings → Partner → Leave partnership. The app also offers Delete all my data, which removes your local profile and workout history and deletes the profile summary and workout summaries from the shared zone so your partner no longer sees them.
Apple's own iCloud and CloudKit services are governed by Apple's privacy policy, not ours.

Notifications

Reminders you schedule (workout reminders, weekly weigh-in) are local notifications generated on your own device. Nothing is sent through any remote server.

When your partner finishes a workout, Fit for Two receives a silent push from Apple's CloudKit; the device fetches the new workout summary from the shared zone and shows you a local notification with the result. No data about you is sent to Apple or anyone else beyond what Apple needs to deliver the push itself.

Photos and camera

If you choose to pick or take an avatar photo, iOS asks you for permission. The photo lives on your device and in the shared iCloud zone (so your partner can see it). It is not uploaded anywhere else.

Analytics, tracking, advertising

None.

Fit for Two does not include any analytics SDK, tracking SDK, or advertising SDK.
Fit for Two does not use the Advertising Identifier (IDFA) and does not request App Tracking Transparency consent.
Fit for Two does not profile you, segment you, or use your data to make decisions about you.
Fit for Two includes no third-party code that phones home.

Crash reports and diagnostics

Fit for Two subscribes to Apple's MetricKit service so that if the app crashes or hangs, iOS writes a diagnostic payload (stack trace, no personal content) to the device, which the app can read the next time it launches. These payloads are stored on your device only. They are not sent to Babbling Comet or any third party unless you email a copy to us at the support address below.

If you choose to email us a diagnostic report, that email contains only the stack trace information iOS produced — no workout data, no HealthKit data, no photos.

Children

Fit for Two is intended for adults and older teens who can safely follow a strength-training program. The app does not collect data from children or market to children. If you believe a child has used the app, email the support address and we will help you delete the data.

Account deletion

Because Fit for Two uses your iCloud account directly, there is no separate "Fit for Two account" to delete. To erase the data the app has created:

Open the app → Settings → Delete all my data. This removes your local profile, workout history, baselines, and weight log, and also deletes your profile summary and workout summaries from the shared iCloud zone so your partner can no longer see them.
(Optional) Delete the app from your home screen. This removes everything else the app stored on-device.
(Optional) iOS Settings → [your name] → iCloud → Manage Account Storage → Fit for Two → Delete Data removes any residual CloudKit records.

Changes to this policy

If we change this policy, we will update the "Last updated" date above and, where the change is material, show a notice in the app the next time you open it.
