Privacy Policy
Effective October 2, 2026
ZeroTo: 0-60 & Drag Timer ("the app") is developed by Vladyslav Shchuka ("we", "us"). This policy explains what happens to your information when you use the app.
What we collect
Nothing automatically. We don't run any servers, there are no accounts, no analytics and no ads. We only receive run files if you email them to us yourself (see below).
Location and motion data
While you record a run, the app reads your precise location, the motion sensors and the barometer. These readings are saved on your iPhone as run files (in the app's folder, visible in the Files app) so results can be shown and recalculated. Location is used only while recording. Nothing is sent anywhere unless you choose to share or export something yourself. Deleting a run, or the app, deletes this data.
Sharing and exporting
When you tap Share with friends, the app creates an image of your result and hands it to the app you pick, such as Instagram or Messages. Export creates a file you choose where to send. From then on, the app you shared with handles that content under its own policy.
Sending run logs to us
You can choose Send run logs for analysis in Settings, or Send log to the developer on a result. The app then opens an email to us with your run files attached. Nothing is sent until you press Send in your email app. Run files contain the GPS track, speed and motion readings of those runs, plus your phone model and iOS version. Your email address comes with the message. We use the files only to check and improve measurement accuracy, keep them only as long as that takes, never share or sell them, and delete them on request. Reply to your email to ask.
Maps
The app shows where your runs happened on an Apple map. The track is drawn on your iPhone; to show the map, Apple Maps loads map images for that area under Apple's privacy policy. We never receive your location.
Purchases
ZeroTo Pro is sold by Apple through the App Store. We never see your payment details. The app only asks Apple whether your Apple Account owns Pro.
Children
The app is not directed at children under 13, and we don't knowingly collect personal information from anyone.
Changes
If this policy changes, we'll update this page and the effective date above.
