Privacy Policy
Effective 9 November 2026
The short version: Zone Work keeps your training on your device and in Apple Health: your settings, your threshold heart rate and zones, and a history of your tests. None of it is sent to us. We don't have accounts, analytics, ads or trackers. The only thing that ever reaches us is an email address, and only if you choose to give one for updates.
Zone Work is an app for iPhone, iPad and Apple Watch made by Kirkcaldy Digital Labs Inc., trading as Kirkcaldy Labs ("we", "us").
On your device and in Apple Health
What the app keeps on your device
- Your settings: the session times, sport and mode you last used.
- Your threshold heart rate for each sport, and the zones worked out from it.
- Your test history: for each test you finish, the date, the sport, how long it ran and the threshold it gave, so the app can show your last test and suggest when to retest. It does not keep the heart-rate readings themselves.
Each device keeps its own: your iPhone, iPad and Apple Watch don't share them with each other. They are included in your device's own backups (for example iCloud Backup, which Apple runs, not us), and they are deleted when you delete the app.
What it does with Apple Health
With your permission, Zone Work:
- reads your heart rate from Apple Health while a session runs, to show your zone and to measure a test;
- saves each session to Apple Health as a workout, with heart rate and energy;
- on Apple Watch, records the route of an outdoor run using location, and saves it to Apple Health with the workout. To do that, the watch also asks to read workouts, routes, energy and distance from Health;
- on Apple Watch, saves a swim as a pool swim workout. The laps, distance and strokes are counted by Apple Watch itself, as in Apple's Workout app. The watch reads that swim distance from Health during the swim, so a warm-up or cool-down can end when its distance is done. It stays on your watch.
None of this is sent to us or to anyone else. We can't see it and can't recover it. Health and location data is never used for advertising, and never shared or sold. You can change these permissions at any time in Settings, and delete the workouts in the Health app.
The optional updates email
When you set up the app you can enter an email address and tap to get occasional emails about Zone Work. If you do, we store:
- your email address;
- the date, and the exact wording you agreed to;
- what you said you're training for, if you picked something;
- the app version.
We use it only to send you emails about Zone Work. Every email has an unsubscribe link. If you unsubscribe, we keep your address marked as unsubscribed so that we never email it again. To have it removed completely, email us.
To stop the sign-up form being abused, we briefly keep a scrambled (one-way hashed) form of the network address each sign-up comes from, for about a day. We never store the address itself.
Purchases
The unlock is sold by Apple through the App Store. Apple handles the payment; we never see your payment details or Apple Account. The app checks your purchase with Apple on your device.
Who processes data for us
- Cloudflare hosts this website and stores the updates list, in North America (the United States and Canada). Cloudflare's privacy policy.
- Apple processes purchases and provides Apple Health. Apple's privacy policy.
We don't sell or rent personal information, and we use no advertising networks, analytics or tracking tools.
Children
Zone Work is not directed at children under 13, and we don't knowingly collect an email address from anyone under 13. If you believe a child has given us one, email us and we will delete it.
Your rights
You can ask us to show you, correct or delete what we hold about you, which is at most the sign-up described above. Email support@zonework.app. If you are outside North America, the address you give us is stored in North America.
Changes
If we change this policy, we'll update the date at the top. If the change matters, and we hold your email address, we'll tell you.
