SplitEye asks for android.permission.CAMERA to watch a small region of the live preview and detect when your marker is covered, so it can start and stop the clock. That analysis - a colour comparison on a handful of pixels - happens entirely on your phone, frame by frame, and is thrown away immediately after. The camera feed is never uploaded, and by default no image or video is ever saved.
Switching this on in Settings saves one video per run - from the start crossing to a few seconds after the finish - into your device's normal Movies/SplitEye folder, the same shared storage any camera app writes to. It shows up in your Gallery and file manager like any other video you've filmed. It is off by default.
These files live only on your phone. SplitEye has no server, so there is nothing to upload them to.
Every timed run - date, time, duration - is written to a small file inside the app's own storage. There's no login and nothing is synced anywhere. Uninstalling the app, or clearing its data, deletes this history for good unless you've exported it first.
The Settings screen can export your history as a CSV file through your phone's own share sheet, or delete it outright. Both only happen when you tap them - SplitEye doesn't send this data anywhere on its own, ever.
SplitEye is free to use, with a limit on how many runs you can time before a short wait. An optional yearly subscription, SplitEye Pro, removes that limit.
Payment is handled entirely by Google Play. Your card or payment details never reach SplitEye or us, and we can't see who subscribes. The app only asks Google Play whether your Google account has an active subscription, and keeps that yes-or-no answer, along with how many free runs you have left, on your phone. You can manage or cancel the subscription at any time in the Play Store under Subscriptions.
The upgrade screen shown once the free runs are used is part of the app itself. It is not an advertising network and shows no third-party content.
After you end a timing session, the app may ask whether you'd like to rate it, using Google Play's own review prompt. Google runs that prompt. If you post a review it appears on Google Play under your Play profile, as with any app; we don't receive anything from the prompt itself.
The "Send feedback" button opens your email app with a message pre-addressed to us, with your app version, device model and Android version filled in to help us track down bugs. You can edit or delete any of that before it's sent - and it isn't sent at all unless you press send yourself.
If SplitEye's data practices change, this page will change with them, and the date at the top will be updated.
