Privacy Policy

What we collect

Nothing personal. marginalia does not collect your name, email address, device identifiers, location, or any personally identifiable information. There are no user accounts, no sign-up flows, and no tracking of how you use the app.

When you open the app, you are anonymous — to us, and to everyone else.

Artwork data

All artwork is sourced from open-access museum APIs — the Metropolitan Museum of Art, the Rijksmuseum, the Art Institute of Chicago, Harvard Art Museums, and Europeana. These institutions make their public-domain and open-access collections freely available. Artwork images and metadata are fetched directly from these APIs by your device.

marginalia does not scrape, cache, or redistribute artwork outside of the usage terms provided by each institution.

AI-generated notes

When you press and hold a painting, a short note about it is generated using Mistral AI. To produce the note, the artwork's public metadata — its title, artist, date, and medium — is sent to Mistral's API. This is a third-party service, so that request leaves your device. The metadata sent is the same information already published by the museum. No personal data, account, or device identifier is ever sent, and the request cannot be associated with you as an individual.

Certain on-device features are powered by Apple Intelligence, which runs locally on your device — nothing is transmitted off-device for those.

No analytics or tracking

marginalia contains no analytics SDKs, no crash reporting services, no advertising networks, and no third-party tracking of any kind. We do not use Firebase, Mixpanel, Amplitude, Crashlytics, or similar tools.

We have no idea how many times you've looked at Vermeer. That's how it should be.

What stays on your device

Any preferences you set (such as recently viewed works or display settings) are stored exclusively on your device and deleted when you uninstall the app. The only data that ever leaves your device is the public artwork metadata sent to the museum and Mistral APIs described above — never anything personal.
