Privacy Policy

Last updated: July 8, 2026

Overview

This Privacy Policy covers how LessLens ("we", "us") handles your information when you use the LessLens app and website.

Information gathering and usage

Your in-app settings and preferences are not personal and are stored only on your device. We do not run our own servers that store your personal information. However, to understand how the app is used, to measure marketing performance, and to keep the app free, we and the third-party services listed below collect a limited amount of data, including a device identifier (such as Apple's advertising identifier / IDFA and vendor identifier) and product-interaction data (for example, which screens and features you use). We do not collect your name, email, contacts, or precise location.

Photos, Scans, and Images

We use the functionality of your device’s TrueDepth sensor to take a scan of your face and derive the specific measurements to optimally display a model of glasses or sunglasses on your face. This processing happens locally on your device using Apple's ARKit. We do not upload, store, or share those photos, scans, images, or any facial data captured in the facial scans with any third parties.

Third-party services and analytics

We use the following third-party services, which may collect a device identifier and usage data under their own privacy policies:

  • AppsFlyer and Tenjin — marketing attribution (measuring which ad or channel led you to install the app).
  • Mixpanel — product analytics (how features are used).
  • Google Tag Manager / Google Analytics — used on our website (lesslens.com), which may set cookies.

Advertising and App Tracking Transparency

On iOS we ask for your permission through Apple's App Tracking Transparency prompt before using your device's advertising identifier to measure advertising and show you more relevant ads for LessLens in other apps and websites. If you decline, we do not use that identifier to track you across apps and websites. You can change this at any time in your device Settings under Privacy & Security → Tracking.

Affiliate links

The app and website contain affiliate links to retailers such as Amazon. When you follow a link and make a purchase, we may earn a commission at no extra cost to you. Those retailers process your activity on their own sites under their own privacy policies and may set their own cookies.

Children’s Privacy

Our Service does not address anyone under the age of 13 (“Children”). We do not knowingly collect personally identifiable information from children under 13. If you are a parent or guardian and you are aware that your Child has provided us with Personal Information, please contact us. If we discover that a Child under 13 has provided us with Personal Information, we will delete such information from our servers immediately.

Changes To This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page. You are advised to review this Privacy Policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page.

You can request the deletion of your data at any time by contacting us by email.
