Museum Guide is made by Sen Lin. This policy explains what happens to your data when you use Museum Guide on iPhone, iPad or Mac.
Museum Guide has no accounts. Your collections, saved artworks, notes and settings, such as the language and appearance you choose, are saved on your device. They are never sent to me.
Find by camera uses your camera to recognise the artwork in front of you. The picture is matched against the museum's artworks on your device, and it is never saved, uploaded or sent anywhere. Museum Guide only uses the camera while Find by camera is open, and you can turn camera access off at any time in your device's Settings.
Narration recordings and full-size images are downloaded from a media server hosted by Cloudflare, and saved on your device so they work offline. These downloads contain nothing about you. Like any web request, they reveal your IP address to Cloudflare, which handles it under Cloudflare's Privacy Policy.
With Premium, Museum Guide can keep your collections and notes the same on all your devices. They are stored in your own private iCloud database, which Apple runs. I can't see what's in it. You can turn sync off at any time in the app's Settings, and you can delete the stored data from iCloud in your device's Settings.
Without Premium, Museum Guide shows a banner ad from Google AdMob at the bottom of each museum's home page.
Museum Guide doesn't ask to track you, so Google can't use your device's advertising identifier. To show and measure ads, Google may collect:
Google handles this data under its own policies. See how Google uses information from apps that use its services and Google's Privacy Policy.
Premium is a subscription bought through Apple's App Store. Apple handles the payment, and I never see your payment details. The app only checks with Apple whether your subscription is active. You can manage or cancel it in your device's Settings or from the app's Settings.
Museum Guide is not aimed at children under 13, and I don't knowingly collect data about them.
If this policy changes, I'll update this page and the date at the top.
If you have questions about this policy, see the Museum Guide support page for how to reach me.
