PRIVACY
Last updated 26 August 2026.
Lazro Fit does not collect your data. There is no account, no server of ours, and no analytics. Everything you log stays on your iPhone.
What the app stores, and where. Your workouts, routines, body measurements, progress photos, runs, custom exercises and settings are written to storage on your own device. They are not uploaded anywhere, because there is nowhere to upload them to: Lazro Fit has no backend. Deleting the app deletes this data with it, which is why the app offers a backup file you can save yourself.
Apple Health. If you turn on the Health connection, the app reads bodyweight, body fat and height so you do not have to type them, reads workouts recorded elsewhere such as on an Apple Watch so your history is complete, and writes your finished workouts and runs back so they count toward your rings. HealthKit data is stored on your device by Apple. Lazro Fit never transmits it, never uses Health data for advertising, and never shares it with anyone. You can turn each direction off separately in the app, or revoke access entirely in the Health app.
Location. 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 position is used on the device to do that and is stored with that run in your own history. It is never uploaded to us. Generating a route sends the start point and requested distance to Apple's MapKit in order to get streets back. That request goes to Apple, under Apple's own privacy policy, and carries no account or identity of ours because we have none. This is the only network request the app makes. 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. Those images are stored on your device with the rest of your data and are never uploaded. When you share a workout image, the iOS share sheet hands it to whichever app you pick; where it goes from there is between you and that app.
Notifications. Notifications are optional and are scheduled by your phone, locally. There is no push server, so nothing about your training leaves the device to send 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 and does not knowingly collect personal information from anyone, including children, because it does not collect personal information at all.
Changes. If this policy ever 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.
