Terms of use and privacy policy

Last updated: 2 November 2026

1. Publisher of the app

My Perfect Museum is published by Artory, an independent developer publishing on a non-professional basis.

Contact: artory.app@gmail.com

For any question about these terms or this policy, or to exercise your rights (section 7), you can write to the address above.

2. What the app does

My Perfect Museum lets you keep track of the artworks you enjoy at exhibitions: photos, artist, title, label text, exhibition, place, date of visit, the people who were with you, tags and personal notes, as well as your favourite museum. The app is designed for personal use.

3. Data we process, and on what basis

Data	Purpose	Legal basis
Photos, texts, notes, names of the people who were with you, which you enter	Operation of the service you request (keeping track of your artworks)	Performance of the service you requested
Text entered to search for a place or a museum	Finding that place on OpenStreetMap	Performance of the service you requested
Geographic location (optional)	Suggesting the name of the museum you are in	Your consent, given through the Android system permission — can be withdrawn at any time in your phone's settings, without affecting the rest of the app
Photos and collection, as a copy (optional)	Cloud backup, so that you never lose your data	Your consent, given by connecting your Google account from the app's Settings — can be withdrawn at any time, without affecting the rest of the app

Your photos and texts are stored by default only on your device. They are never sent to a server that belongs to us.
If you turn on cloud backup (optional), a copy of your photos and your collection is placed in your own Google Drive — we have no access to it; it is held by your Google account.
If you export a backup file (optional, Settings, "My data"), a file containing your photos and your collection is created on your device, then saved or sent wherever you choose. This file is not encrypted: keep it somewhere safe. We have no access to it.
Location, if you allow it, is used only occasionally, when you ask the app to look for museums where you are: the location button of the Place field, or the search for the nearest museums in Settings. Your coordinates are then sent to the public OpenStreetMap services (Overpass, and Nominatim as a fallback) for that search only, and are not kept anywhere beyond that use.
Searches for a place by name (your favourite museum, the place of a visit) send the text you enter to Nominatim (OpenStreetMap), only when you start the search.
The label text is recognised on your device by Google ML Kit, which, as part of its operation, sends Google technical statistics and a technical identifier of the installation that is not linked to your identity (see section 4) — never the content of your photos or your notes.
“Identify the artwork”: only if you ask for it, the chosen photo is handed over to the Google app (Google Lens), or to the image search app you choose, which processes it under its own terms. The app receives nothing back: you copy the title and the artist yourself.
No account specific to the app is created or required. We do not know who you are. If you connect your Google account for backup, its email address is kept only on your device, to show the connection status.
Automatic backup by the Android system: independently of the cloud backup above, your phone may automatically back up your collection (artworks, notes, visit companions) and your settings, but not your photos, as part of its own Android backup system — a standard feature of your phone, not a feature of the app; you can manage it from your device's backup settings. This data may be restored if you reinstall the app.

4. Third-party services used

Service	Function	Data sent
Nominatim (OpenStreetMap)	Museums near your location; search for a place or a museum by name	One-off GPS coordinates; text entered in the search; no identity
Overpass (OpenStreetMap)	As a fallback, museums and galleries near your location	One-off GPS coordinates, no identity
Google ML Kit	Recognition of the label text, on your device	Technical usage statistics and a technical identifier of the installation (not linked to your identity), sent to Google — never your photos or your texts
Google Lens (Google app)	“Identify the artwork”, only if you ask for it	The chosen photo, sent by your phone to the Google app
Google Drive	Cloud backup, only if you turn it on	Your photos and your collection, placed in your own Google account

As with any internet connection, these services also receive your device's IP address. Privacy policies: OpenStreetMap Foundation, Google.

No data is sold to third parties or used for advertising purposes.

5. Where your data is stored, and for how long

By default, your data is stored exclusively on your device, for as long as you use the app or until you delete it yourself:

deleting an artwork: immediate on the device, with a few seconds to undo it, then permanent (and carried over to the next backup, if cloud backup is turned on);
uninstalling: complete deletion from the device; any copies (Android backup, Drive backup) remain under your control in your Google account.

If you have turned on cloud backup, a copy also exists in your Google Drive, in the folder “Mon Musée Idéal — Sauvegardes”, under your sole control. To stop the backup, use “Sign out” in the app's Settings: the permission given to the app is removed from your Google account and backups stop. The backup already there stays in your Google Drive, where you can delete it. To delete it at the same time, choose “Sign out and delete the backup”: the backup folder is moved to the trash of your Google Drive (recoverable for 30 days, then erased by Google); your artworks stay on your device.

We keep no copy of your data on a server that belongs to us.

6. Security

Since your data is stored locally, its security depends first and foremost on the security of your device (screen lock, system updates). The app does not send your photos and texts to any server belonging to us. If you turn on cloud backup, they are sent to your own Google Drive. All of the app's communications are encrypted (HTTPS).

7. Your rights

In accordance with the General Data Protection Regulation (GDPR), you have, regarding any data concerning you, the right:

of access — to know what data is recorded (it is all visible directly in the app);
to rectification — to correct any information at any time, directly in the app;
to erasure — to delete an artwork, or uninstall the app to delete everything from the device; to delete the backup from your Google Drive, from the app (Settings, “Sign out and delete the backup”) or directly in your Google Drive;
to restriction of and to object to processing — to withdraw the location permission at any time (system settings) or sign out of cloud backup (the app's Settings), with no consequence for the rest of the app;
to portability — your backed-up data, if you turn on cloud backup, remains accessible and exportable directly from your own Google Drive (photos and collection file); you can also export your whole collection, photos included, to a file (Settings, "My data").

You exercise these rights directly yourself, in the app or through your device's settings, since we hold no copy of your data on a server that belongs to us. For any question, you can also contact us at the address given in section 1.

Finally, you have the right to lodge a complaint with the competent supervisory authority, the CNIL (Commission Nationale de l'Informatique et des Libertés, the French data protection authority) — www.cnil.fr.

8. Minimum age

This app is not specifically aimed at children and does not knowingly collect data about minors. If you are a minor, you must use this app with the permission of your legal guardian.

9. Changes to this policy

This policy may change, in particular if new features involving data processing were added. Any substantial change will be brought to your attention, and you will be asked to accept it again before continuing to use the app.

Terms of use

1. Personal use. The app is intended for personal use, to keep track of your exhibition visits.

2. Content you add. You alone remain responsible for the photos and information you record, including the names of the people who are with you, and you must have the right to capture them (see each museum's rules on photography).

3. Intellectual property in the artworks. The artworks you photograph may still be protected by copyright; the app is a tool for personal remembrance, not a tool for publishing or sharing.

4. Availability of the service. The app is provided “as is”, with no guarantee of continuous availability, in particular for the features that depend on third-party services (place search with OpenStreetMap, backup with Google Drive).

5. Limitation of liability. To the extent permitted by law, the publisher cannot be held liable for any loss of data resulting from a malfunction of your device, an uninstallation, or use that does not comply with these terms. The app offers an optional backup to your Google Drive, with no guarantee that it runs properly; it is up to you to check that it is active if you want to protect your data.

6. Minors. If you are a minor, you confirm that you use this app with the permission of your legal guardian.

7. Ending use. You can stop using the app at any time by uninstalling it, which deletes your data from the device (section 5); any copies in your Google account remain under your control.

8. Governing law. These terms are governed by French law. Any dispute, failing an amicable resolution, falls within the jurisdiction of the competent courts.

By using this app, you confirm that you have read and accepted these terms and this privacy policy.
