Privacy Policy — Foulée

Last updated: October 29, 2026

Foulée is a local app. It helps you keep up a streak of outings — walks or runs — from your activity data. No data is sent to any server of ours, and there is no account to create. Everything stays on your devices: your iPhone, your Apple Watch, and your Garmin watch if you install Foulée’s Connect IQ app on it. Only your settings and your outing merges also go through your iCloud, at Apple, to follow your other iPhones (see “iCloud”).

Health data (HealthKit)

With your permission, Foulée reads from the Health app: your steps, your distance, your exercise minutes, your active calories, your heart rate, the water you drank, your workouts and their routes. This data is used only to show your statistics and your outings in the app, and to work out your streak. The Hydration screen also shows each of the day’s glasses with the name of the app that logged it in Health.

Foulée also writes to the Health app, if you want it to: your outings (as workouts, with their route when they are recorded on the Apple Watch) and the water you log in the hydration tracker. When you undo a glass, Foulée deletes from Health the entry it has just written, and only that one: Health does not let an app delete data written by another.

This health data never leaves your device: it is neither passed on to a third party nor stored anywhere other than Apple’s Health app, which you fully control.

Garmin watches

If you wear a Garmin watch, your data reaches Foulée through the Health app, like all the rest: Garmin Connect writes it there, and Foulée reads it on your device, whatever its source.

Foulée never talks to Garmin’s servers: no Garmin account sign-in, no Garmin API, no exchange with any server — neither ours nor Garmin’s. The promise stays the same — your health data never leaves your devices.

The Foulée app for Garmin watches (Connect IQ)

Foulée also offers a small app to install on the watch itself, from the Connect IQ Store. It is optional: without it, everything keeps working through the Health app, as described above.

What it reads on the watch — only the day’s counters the watch already keeps (ActivityMonitor): your steps, your distance, your active minutes, your vigorous active minutes and your calories. Outside a session, no GPS, no heart rate, no sensor switched on for the occasion.

During a session you start on the watch — the watch records the activity itself, with its own recorder, like its sports apps: duration, distance, GPS position and heart rate. GPS and the heart rate sensor are only on from “Start” to “Save” or “Discard”. A saved session goes to Garmin Connect like any other activity from your watch, and Garmin Connect writes it to Health; a discarded session leaves no trace. Of your position, Foulée’s watch app keeps only the session’s route, thinned out, for your iPhone (see below): it stays on the watch only until the iPhone receives it.

During the session, when your iPhone is in range, it also sends it, every ten seconds as well as on pause, resume and finish, where the session stands: walk or run, time of the reading, duration, distance, steps, current heart rate, paused or not, finished or not. The iPhone shows it on its session screen and does not keep it once the session is over. Only the “finished” state waits until the iPhone has received it, so that its screen does not stay open.

What it sends — a snapshot of these five values, plus the time of the reading, the time your day starts on the watch (to count the values on the right day when the watch and the phone are not in the same time zone), the message type, the format’s version number and a send number that lets the iPhone ignore a snapshot it has already received. All of it goes straight to your iPhone over Bluetooth, at most once every five minutes, and only if these values have changed since the last send. When the phone is out of range, the watch sends nothing and simply waits for the next chance.

At the end of a saved session, it also sends its summary: walk or run, start and end time, duration, distance, ascent and descent, steps and the session’s route, reduced to 64 points at most. The iPhone uses it to show the outing and its map until Garmin Connect writes it to Health, which receives it without a route. The summary waits on the watch until the iPhone has received it (along with session ends and glasses, the last thirty-two messages at most); heart rate is not part of it. The iPhone keeps the route with the pending outing, and forgets it along with it.

When you tap “Log a glass” in the watch’s menu, it sends the glass: its time, its amount and an identifier. The watch cannot write to Health: the iPhone writes it there, with that identifier, so that a glass received twice only counts once.

On your watch face, if you add the “Foulee streak” complication, the watch shows your streak. The complication is public, like the watch’s own: any installed watch face can read it. It does not leave the watch.

What it receives — from your iPhone, over the same Bluetooth link: your streak, your step and minute goals, your walk / run choice and your hydration settings (on or off, goal, glass size). That is what the Apple Watch already receives. During a session, if you tap “Stop the session” on the iPhone, the watch also receives the order to save it. The watch keeps the last state it received to show it when the phone is out of range.

What it does not send — nothing goes to Garmin’s servers, nor to ours (we have none). There is no account to create in this app, no setting, and nothing is stored anywhere but on the watch and on your iPhone.

Once on the iPhone, these values follow exactly the same path as the others: they are used to show your statistics and work out your streak, and stay on your device.

It is of no use without the iPhone app. Installed on its own, it only shows your day’s counters on the watch.

Location

With your permission (“while using the app”), Foulée uses your location for two things, and never anything else:

For the weather, your coordinates are sent to Apple WeatherKit, which returns the local conditions (see Apple’s privacy policy).

The route of an outing made with the Apple Watch is saved in the Health app, with the workout, as Apple’s Fitness app does: that is what lets you see it again on a map in Foulée, in Fitness or in any app you give access to Health. It stays on your devices, in Health, which you fully control, and is sent to no one. The route traced by the iPhone, for its part, is not kept after the outing.

Motion and fitness

Foulée uses the pedometer (CoreMotion) to count your steps live during your outing and, on the Apple Watch, to read your current cadence and pace: they are shown on your wrist and help tell whether you are walking or running. This data is processed locally, in real time.

With your permission, Foulée also reads the system’s motion detection to tell on its own whether you are walking or running:

In both cases, the reading is used to save your outing under the right sport in Health. Nothing is sent, nothing is kept outside the session itself.

During a session, the barometer of the iPhone and the Apple Watch measures the elevation you climb and the elevation you descend. Only these two totals are kept: they are saved with the session in Health, like its distance.

What Foulée does not do

Preferences

Your settings (goal, activity, window, theme, reminders) are stored on your device, and follow your other iPhones through your iCloud (see “iCloud”).

The summary of the last 7 days and of the month is worked out on your iPhone, from the Health data Foulée already reads. Its notification is scheduled locally: nothing is sent anywhere to produce it.

The notification that follows a session arriving from a watch is worked out the same way: your iPhone compares the outing with those of the last six months, read from Health, and schedules the notification itself. Nothing leaves your iPhone to write it.

When you merge two outings, Foulée remembers on your iPhone which workouts make up one, and nothing else: Health is not changed. The merge follows your other iPhones through your iCloud (see “iCloud”). Splitting the outings erases that link, everywhere.

iCloud

So that a new iPhone, or a reinstall, gets your settings back, Foulée also keeps them in your iCloud, with Apple’s key-value storage. They are at Apple, in your account, never with us: we have no server and cannot read them. Only your devices signed in to the same iCloud account receive them.

What goes through iCloud:

What does not: your health data — steps, distance, heart rate, water, workouts, routes — and your location. They stay in Health, which has its own iCloud sync, run by Apple and not by Foulée.

To turn it off: iOS Settings → your name → iCloud, then turn Foulée off in the list of apps using iCloud. Your settings then stay on this iPhone only.

To erase everything: Settings › “Reset Foulée” puts every setting back to its default and undoes every merge, on this iPhone and, through iCloud, on the others. Nothing in Health is touched.

Diagnostics

On the iPhone, Foulée receives from iOS (MetricKit) the reports of its own crashes, hangs and slow launches. It keeps ten at most, for a month at most, on your iPhone. These reports describe how the app runs — version, device model, iOS version, technical traces — and contain no health data and no location.

Nothing leaves on its own. In Settings › About, “Report a problem” shows you the summary before anything is sent:

Uninstalling the app deletes these reports.

Apple privacy manifest

The app and its extensions (widgets, Watch app) ship a privacy manifest (PrivacyInfo.xcprivacy), Apple’s standard format for declaring what an app does with your data. Foulée’s declares:

Your settings going through your iCloud is not collection: they go to your Apple account, not to us.

Your choices

You stay in control at any time from iOS Settings:

Deleting the app erases the preferences it stored on the device; those kept in your iCloud stay there for your next install, unless you first use “Reset Foulée”. The data in the Health app remains managed by Health.
