Loupe: Photos on Your Wrist · Last updated: 8 October 2026

Loupe is made by Superluminal LLC. The short version: Loupe collects nothing. We have no servers that receive your data, no accounts, no ads and no tracking. This page explains what the app does, where your data lives, and the choices you have.

What Loupe does

Loupe keeps the photo albums you choose on your Apple Watch, with an iPhone companion. The iPhone app reads your photo library, with your permission, and prepares each photo. The Apple Watch app keeps them, so you can look at them with no iPhone nearby.

Data we do not collect

Loupe has no accounts, ads, tracking, analytics of its own or third-party code. We never receive your photos, videos, albums, photo details such as dates, favorites or locations, your contacts, your location, your device identifiers or your purchase history. We do not sell or share personal information, because we do not have any.

Data that stays on your devices and in your iCloud

Loupe moves photos and videos from the albums you pick to your Apple Watch in two ways: directly between your iPhone and your Apple Watch, and through your own private iCloud whenever it can. A photo keeps its details, such as its date and location, inside the file, and the file goes only to your own devices, your own iCloud, and anyone you choose to share it with.

Your private iCloud. Loupe uses CloudKit, Apple’s iCloud service for apps. The iPhone puts copies of photos in a private database that belongs to your Apple Account, inside Loupe’s iCloud container. A private database can be read only through your Apple Account, and Superluminal cannot read it. The copies and their details are encrypted and are deleted once your Apple Watch has them. A copy that your Apple Watch has not collected is cleaned up after 48 hours by default. Copies use at most about 1 GB of your iCloud storage. Your album list (titles, photo IDs, dates and favorites) also stays there, so your Apple Watch can show it.

One public setting. Loupe also reads one public record from Loupe’s iCloud container. It holds a single number: how many hours a copy may wait in your iCloud before it is cleaned up (between 1 hour and 14 days). Reading it sends nothing about you, and it works with no iCloud account.

If iCloud is off or full, photos go directly from your iPhone to your Apple Watch instead, and Loupe still works.

Apple services the app uses

Your passcode and the Hidden Album

You can lock Loupe with a passcode and keep photos and videos in the Hidden Album. Your passcode is kept on your iPhone and Apple Watch as a scrambled check value, never as the code itself. Hidden Album photos and videos are kept in Loupe on your iPhone and Apple Watch, and move only through your own iCloud or directly between your devices. Nothing about your passcode or the Hidden Album reaches us.

Diagnostics log

Diagnostics is a switch in Loupe’s Settings, and it is off until you turn it on. While it is on, Loupe keeps a log of syncing on your iPhone and on your Apple Watch, to help with support. The log lists what happened and when: the sync steps, counts and any errors. Photo IDs in it are scrambled, and details such as album titles are left out. It holds no photos and no videos.

The log stays on your device. It leaves your device only if you tap Share Log. That puts the iPhone log, the Apple Watch log and a short note with the Loupe and iOS versions into one zip file and opens the share sheet, and you choose where it goes, for example Mail. If you send it to us, we use it only to look into the problem you reported. Loupe never sends it by itself. The log is limited in size, and turning Diagnostics off stops Loupe from adding to it.

Children

Loupe is not directed at children under 13, and we do not knowingly collect personal information from anyone, children included. Loupe collects nothing from anyone.
