Effective October 20, 2026 · Applies to the Lucent iOS/iPadOS app

In one sentence: Lucent is designed as an on-device camera — it has no account system, no advertising SDK, no tracking, and no developer-operated upload service. From version 1.1.3 it sends anonymous usage analytics, which you can turn off in Settings; your photos, videos, camera frames and audio never leave your device unless you share them.

Camera and microphone

Lucent processes camera frames and, when you allow microphone access, audio on your device to create captures and live monitoring (histograms, waveforms, audio meters, guidance). Lucent does not transmit those camera or microphone streams to the developer or to any third party.

Captures and metadata

Original masters and JSON metadata sidecars are stored in Lucent’s Documents folder on your device, or in an external folder you explicitly select. iOS File Sharing can make the app’s Documents folder available through the Files app or a connected computer — that is a system feature under your control.

Sharing and deletion

A capture leaves its storage location only when you choose a system share, export, or Save to Photos action. Photos library access is add-only and is used only for items you explicitly save. Deleting a master in Lucent permanently removes the media file and its metadata sidecars from that location.

Purchases

Apple processes all subscription purchases. Lucent verifies subscription entitlement status on device (via Apple and RevenueCat’s entitlement service) to unlock Pro features. The developer never receives your payment-card details. Purchase receipts are validated by Apple; RevenueCat processes an anonymous app-generated identifier and purchase state solely to keep your Pro access in sync — see RevenueCat’s privacy policy. RevenueCat also forwards subscription status events (for example a trial starting, a renewal or a cancellation) to Lucent’s analytics project under the same anonymous identifier described below.

Usage analytics

To learn which features help people and where the app falls short, Lucent (version 1.1.3 and later) sends anonymous usage events to Mixpanel, with data stored in the European Union. Examples: screens and onboarding pages opened, capture modes, looks and lenses used, how long a capture lasted, camera start-up time and errors, and the steps of a purchase.

• Events are tied to a random identifier created on your device — not to your name, email address, phone number, or advertising identifier.
• Lucent does not use your IP address to determine your location; the country comes from your device’s region setting.
• Events never include photos, videos, camera frames, audio, file names, or teleprompter text.
• The data is used only to improve Lucent; it is not sold, used for advertising, or combined with data from other companies’ apps.
• You can turn analytics off at any time in Lucent: Settings › Share Usage Analytics. Turning it off stops sending and discards events still waiting on the device.
