Terms of Use

Proteus · Last updated 29 October 2026

These terms cover your use of the Proteus app and service. Your use of the app downloaded from the App Store is also governed by Apple’s Standard End User License Agreement, and from Google Play by Google Play’s terms.

Your account

Keep your sign-in details private. You are responsible for what is posted from your account. We may suspend accounts that post unlawful, abusive or infringing content, or that abuse the service.

Community rules

Proteus has no tolerance for objectionable content or abusive behaviour. Do not post or send anything that is unlawful, hateful, harassing, threatening, sexually explicit, violent, or that infringes someone else’s rights, and do not use Proteus to spam or impersonate others. You can report any post, comment or collector from the app, and block anyone you do not want to hear from. We review every report within 24 hours, remove content that breaks these rules, and suspend or remove the accounts that posted it.

Your photos and posts

You keep the rights to the photos you take. You give Proteus permission to store and process them to identify works and keep your collection, and to show what you choose to share to the people you share it with. Works of art and their images belong to their owners and museums; catalogue information comes from Wikidata and Wikimedia Commons under their licences.

Identifications

Each account may identify up to ten works a day; each use returns 24 hours after it is spent. Identification is automated and may sometimes be wrong. Proteus is free: there is nothing to buy in the app.

A collection is of works you have seen in person. Photos of screens, screenshots and images saved from the web do not count. We review collections that look gathered that way, and may reset them and mark the account as one that misrepresented its collection.

Privacy

How we handle your information is described in our Privacy Policy.

Changes and contact

We may update these terms; we will say so in the app when we do. Questions: projectproteusllc@gmail.com.
