How IPD Measure, published by Pinnacle Parameters, handles information when you use the app.
Effective date — 2026-04-26
IPD Measure does not collect, store, or transmit any personal data. The app processes camera frames entirely on your device to estimate your pupillary distance and discards each frame after processing. No images, measurements, account information, or analytics are uploaded to any server.
We do not collect, request, or store any of the following:
The app does not include third-party analytics, advertising, attribution, or tracking SDKs of any kind.
When you tap “Start measuring,” the app requests permission to use your device’s front camera. With your permission, the camera feed is processed in real time on your device by Google MediaPipe’s face landmarking model. The model detects the position of your irises within each frame; the app uses your iris diameter (which is biologically consistent in adults) as a known scale reference to estimate the distance between your pupils.
Each frame is processed in memory and immediately discarded. No frame, image, or detection result is stored on disk, written to the photo library, transmitted over the network, or shared with any third party. The final estimated pupillary distance value is shown on screen during the session and is not retained after the app is closed.
The app is built using the following open-source libraries, all of which execute locally on your device and do not transmit data to remote servers in connection with the app’s core functionality:
A complete list of attributions and license types is available within the app under About → Open source notices.
The app contains one optional external link on the result screen (“Buy me a coffee”) that, if tapped, opens buymeacoffee.comin your device’s default web browser. If you choose to follow this link, you will leave the app and visit a third-party website, which is governed by its own privacy policy and terms. We do not control and are not responsible for the privacy practices of buymeacoffee.com or any other third-party site.
The app may also open your device’s system settings (when prompted to grant or restore camera permission) and your default mail application (when contacting support). These actions do not transmit any information to us.
The app requires permission to use your device’s front-facing camera in order to detect your irises and estimate your pupillary distance. The camera is activated only after you explicitly accept the in-app disclaimers and tap “Start measuring.” The camera feed is never recorded, saved, or transmitted.
You can revoke camera permission at any time through your device’s system settings:
Without camera permission, the app cannot estimate pupillary distance, but no other data is collected or retained.
IPD Measure is not directed to children under the age of 13 (or under 16 in jurisdictions where the GDPR digital-consent threshold applies). We do not knowingly collect personal data from children. Because the app does not collect any personal data from any user, no special children’s-data handling provisions apply.
For users in the European Economic Area, the United Kingdom, Switzerland, or California: because IPD Measure does not collect, store, transmit, or share any personal data, no rights of access, rectification, erasure, restriction, portability, or objection apply, and there is no personal information for us to disclose, sell, or share. Pinnacle Parameters does not act as a data controller or data processor (or as a “business” or “service provider” under the CCPA/CPRA) for any personal data of app users in connection with the app’s operation.
Because no personal data is collected, no personal data is retained.
Because we do not collect, store, or process personal data through the app, there is no personal data for us to access, correct, export, or delete on your behalf. If you have questions about this, please contact us using the details below.
IPD Measure provides an estimate for personal use only. It is not a medical device, is not certified, calibrated, or regulated as a medical instrument, and is not intended to diagnose, treat, or prevent any condition. The app should not be used to order prescription eyewear, complete medical or insurance forms, or as the basis for any health, vision, or safety-related decision. For an accurate, official pupillary distance measurement, please consult a licensed optician or eye-care professional.
We may update this Privacy Policy from time to time, for example to reflect changes to the app, our practices, or applicable law. Any updates will be posted on this page with a revised effective date. Because the app does not collect data, material changes to this policy are unlikely. We encourage you to review this page periodically.
