Privacy Policy: RangeDot
Last updated: 2026-10-22 (draft)
RangeDot ("the app") is published by SIA "ZeroLN", registration No. 40203796385, registered office 5 Meldru iela, Sigulda, Siguldas novads, LV-2150, Latvia ("we"). This policy covers the app on Android and iOS. We are the data controller for the limited data described under "Contacting support".
Summary
The app does not collect, store on any server, share, or sell any personal data. It has no accounts, no advertising, no analytics and no tracking, and it does not connect to the internet.
What the app uses on your device
- Camera: to watch your paper target and find new bullet holes. Images are analysed on your phone.
- Microphone (optional): to hear the bang of each shot, count shots and check the target. The sound level is analysed live. The sound is saved only as part of a session video (see Storage), and only while you watch a target.
- Debug mode (off by default): when you turn it on in Settings, each session also saves a video of the screen view and a log of app events (and the session video, see Storage). These files help to find detection problems. They stay in the app's own storage on your phone. They leave the phone only when you attach them to a Support email (see "Sharing"). Settings > Debug shows how much space they use, and "Delete debug data" deletes them from all sessions. They are also deleted with the session.
- Storage: each session (a reference image, one image per shot, a video of about 1 second of each shot without sound, a small file with shot positions and app settings, and, when "Save session videos" is on (it is on by default; you can turn it off in Settings), a video of the analysed camera image with the microphone sound, from Start to Finish) is saved inside the app's own storage on your phone. While the app watches, it records the camera image for these short videos, and it deletes the longer recording as soon as the short videos are cut. On iOS, sessions are visible in the Files app under the app's folder.
- Your photos and videos: the app does not open or show the photos and videos of your phone.
- Photos / Gallery: only when you tap Save, the session images are added to your photo library. On iOS, the app asks only for permission to *add* photos, never to read them.
Sharing
Nothing is sent anywhere automatically. Two actions on a saved session can send data, and only when you choose them:
- Share session sends the images, the short shot videos and the session video of that session to an app that you pick in the share sheet of your phone, for example WhatsApp, Messages or your email app. It sends no debug files.
- Support (in the same share sheet) opens a form. When you press "Write the email", the app packs the files of that session into one zip file: the images, the short shot videos, the session video and the file with shot positions. If Debug mode was on and you leave "Attach the debug files" on, the zip file also holds the screen video and the log (with app settings). The session video holds the microphone sound. The email also contains your text, the app version, the phone model and the OS version. The videos and the audio can show people and voices near the camera; the form tells you this and the size of the files. Your email app then opens with the email: you can read and change it, and you decide whether to send it. The app keeps its copy of the zip file only until the next zip or the next start of the app.
If you send a report to us, we use it only to fix the problem you reported, and we delete it within 90 days after the fix is released, unless you agree that we keep it as a test case.
Contacting support
If you email us, we process your email address, your message and any attachments you choose to send. We use them only to answer you and fix the problem. The legal basis is our legitimate interest in providing support (GDPR Art. 6(1)(f)). We keep support emails for up to 12 months after the case is closed, and attachments as described under "Sharing". We don't share them with anyone except our email provider, Google Ireland Limited (Google Workspace), which processes them on our behalf.
Your rights (GDPR)
You can ask us for access to, correction of, or deletion of the personal data we hold about you from support contacts, and you can object to its processing. Write to support@zeroln.com. You can also complain to the Latvian Data State Inspectorate (Datu valsts inspekcija, www.dvi.gov.lv) or to the data protection authority in your own country.
Your control
You can delete any session in the app. Uninstalling the app removes all its data from your phone. Images you saved to your photo library stay there until you delete them.
Children
The app is intended for adult target shooters and is not directed at children.
Changes
If this policy changes, the new version will be posted on this page with a new date.
