Lazro Fit is a free gym and running log for iPhone. No account, no subscription, no ads. Everything you log stays on your phone, with a backup in your own iCloud.
PRIVACY
Last updated 27 September 2026.
Lazro Fit does not collect your data. There is no account, no server of ours, no analytics and no advertising. Nothing you log is ever sent to us.
What the app stores, and where. Your profile (the name, birth date, sex, height, bodyweight and picture you choose to enter), workouts, routines, body measurements, progress photos, runs, custom exercises, gyms and settings are stored on your iPhone. The app also keeps a backup of them in your own iCloud, described below, unless you turn that off.
Your iCloud backup. The app backs up your data to your own private iCloud, under your Apple ID and against your own iCloud storage. It is on from the start and needs no setup, so that losing or replacing your phone does not mean losing your training history. It is kept in the private database of the app's iCloud container (iCloud.com.cobeyabbott.lazrofit), which only your Apple ID can read.
The developer cannot read or receive it. Apple stores it for you under Apple's own privacy policy. Unless you have turned on Advanced Data Protection for iCloud, Apple holds the keys to it, as it does for the rest of your iCloud data.
The backup includes your profile, workouts, routines, the measurements you entered, runs with their routes, progress photos, custom exercises, gyms and settings. From version 1.0.6 it does not include readings or workouts read from Apple Health (see below). The first backup after updating replaces any earlier copy; if you have turned backup off, an earlier copy stays until you delete it.
To turn it off: tap your picture at the top right, then Data & privacy, then "Back up to iCloud". To delete it: the same screen has "Delete iCloud backup". Deleting the app removes the data on your phone but leaves the iCloud backup, so that a reinstall can bring your history back; delete the backup in the app, or in your iPhone's iCloud settings, if you want it gone.
Deleting your data. Tap your picture, then Data & privacy, then "Delete all data". It erases your workouts, runs, photos and measurements on this phone, and your custom exercises, gyms and folders, and puts your routines back to the starter set. Workouts the app saved to Apple Health go too. Your profile details stay until you change them, and the iCloud backup stays until you delete it with "Delete iCloud backup": deleting turns "Back up to iCloud" off, so that copy is kept rather than replaced. If Apple Health is still connected, the app reads the last ninety days from it again the next time it opens; turn off "Connect to Health" first if you do not want that.
Apple Health. If you turn on the Health connection, the app reads your bodyweight and body fat so you do not have to type them, and runs and walks recorded elsewhere (such as on an Apple Watch) so your history is complete. It writes your finished workouts and runs, with their distance, to Apple Health.
Data read from Apple Health stays in Apple Health and on your phone. It is not included in your iCloud backup (from version 1.0.6). After a restore, once you reconnect Apple Health, the app reads it again from whatever Apple Health on that phone holds. Lazro Fit never sends Health data anywhere itself, never uses it for advertising and never shares it with anyone; a CSV or backup file you export, or a workout card you share, can include it, because you chose to. You can revoke access at any time in the Health app.
Location is used for two things: drawing a running or walking route from where you are standing, and measuring the distance and pace of a run in progress. Your route is stored with that run in your own history, and in your own iCloud backup if backup is on. It is never sent to us.
Network requests. The app makes only two kinds of network request, and none of them reaches the developer:
Apple Maps. Generating a route sends the start point and the points around it to Apple's MapKit, which returns streets. The map picture shown on a run is drawn by Apple's MapKit too. These requests go to Apple, under Apple's own privacy policy, and carry no account or identity of ours because we have none.
Your iCloud backup, described above, which goes to your own iCloud.
Logging, and recording, saving and reviewing a run, all work with no connection at all.
Camera and photos. The camera and photo library are used only when you choose to add a progress photo or a profile picture, or to save an image you share. Those images are stored on your phone and in your own iCloud backup if backup is on, and are never sent to us. When you share a workout image, iOS's own share sheet hands it to whichever app you pick; where it goes from there is between you and that app.
Notifications are optional and are scheduled by your phone, locally. There is no push server, so nothing about your training leaves the phone to send them.
Turning permissions off. Location, the camera, photos and notifications can each be turned off at any time in your iPhone's Settings app, under Lazro Fit, and access to Apple Health in the Health app. Turning one off stops only the feature that uses it; logging a workout needs none of them.
Data you export. The CSV and backup files the app creates are yours. They are written where you tell iOS to put them, and we never see them.
Children. Lazro Fit is a general-audience fitness app. It does not collect personal information from anyone, including children.
Changes. If this policy changes, the updated version will appear at this address with a new date at the top. Any change that would involve collecting data would be a change to what the app is, and would be described plainly here and in the App Store release notes.
