range · last updated 28 August 2026
Range does not collect your data. There is no account, no server, and no analytics service. It also requests no permissions at all — not the camera, not your photo library, not anything else.
Range declares no permission usage strings, which means iOS never shows you a permission prompt for it. This is not a technicality; the app is built so it does not need any:
When you choose a photo, it is held in memory while Apple's on-device Vision framework proposes body landmarks and while you position the markers. When you close that screen, the image is released.
Range never stores your photograph. It is not written to disk, not copied into your photo library, not attached to the saved measurement, and not uploaded anywhere. Nothing about it can be recovered afterwards, by us or by you, because nothing was kept. The pose detection happens entirely on your iPhone; no image is ever sent to a server for analysis.
What is saved from a measurement is the number and its labels, described below.
Range saves the following locally, using Apple's on-device database:
This data never leaves your device unless you deliberately export it. It is not backed up to any server operated by us. If your iPhone is included in an iCloud or encrypted local backup, this data may be included in that backup, under Apple's control and covered by Apple's privacy policy.
Settings has a Delete all measurements option that erases everything immediately. Deleting the app also deletes all of it, permanently.
You can export your measurements as a CSV file or a plain text summary. This happens only when you ask for it. The file is written to a temporary location and handed to the iOS share sheet, and where it goes from there is entirely your choice — we never receive a copy and have no way to.
Range makes no network requests of its own. It contains no networking code at all. The only time the app causes any network traffic is when you open the subscription screen and the App Store fetches current prices, which is handled by Apple's own code, not ours.
Range contains no advertising, no third-party SDKs, no tracking pixels, and no cross-app or cross-site tracking of any kind. The App Tracking Transparency prompt is never shown because there is nothing to ask you about.
Range Pro is sold through Apple's In-App Purchase system. We never see your payment details, your name, or your Apple Account. Apple tells the app one thing only: whether a valid subscription is currently active. Apple's handling of purchase data is governed by Apple's privacy policy.
Range is rated 4+. Because the app collects no data at all, it collects no data from children either. There is no messaging, no user-generated content, and no way for one user to contact another.
Regulations such as the GDPR and the CCPA give you rights to access, correct and delete personal data held about you. We hold none, so there is nothing for us to return or erase. The data described above is on your own device and entirely under your control — you can see it in the app, export it, and delete it from Settings or by deleting the app.
If this policy changes, the updated version will be posted at this address and the date at the top will change. If a future version of Range ever collects anything, that change will be described here before it ships, and in the app's release notes.

Range is a measuring tool for tracking your own flexibility over time. It is not a medical device, it does not diagnose, treat or assess anything, and the typical ranges it shows are population averages rather than targets. If something hurts, see a physiotherapist or a doctor.
