In short: your collections, photos and prices stay on your phone. We have no server that receives them. No ads, no trackers, no cookies.

In the app

Your collections

Everything you enter (collections, items, photos, prices, ratings, tags, journal) is saved only on your device, in the app's private storage. This data is neither sent to our servers nor shared with third parties. It only leaves your device if you create a backup or an export yourself and choose to share it.

Photos and camera

The app asks for access to your photo library or camera only when you add a photo. The selected images are copied and resized within the app's storage. When you save a shared image to your gallery, the app only asks for permission to add a photo there, not to read yours. You can withdraw these permissions at any time in your phone's settings.

Shared images

The image of a piece or a collection is created on your phone, with no connection. It only contains what you see in the preview: a hidden price never appears on it. It only leaves your device if you share it yourself, with the app of your choice.

Pro subscription (from V1.3)

At launch, the app offers no payments. From version 1.3, payments will be processed by Apple (App Store) or Google (Google Play). We never see your bank details. To check that a subscription is active, the app uses RevenueCat (RevenueCat, Inc., United States), which receives an anonymous identifier generated by the app and the purchase history provided by the store. No data from your collections is shared. Transfers outside the European Union are covered by the European Commission's standard contractual clauses.

What the app doesn't do

  • No advertising, no advertising identifier.
  • No audience measurement or usage statistics.
  • No selling or renting of data.

On this site

This site sets no cookies and uses no audience measurement tool, no third-party script, and no font or resource loaded from another site. Like any host, Cloudflare keeps technical logs (IP address, date, requested page) for a limited time to keep the service secure. Cloudflare is based in the United States: these transfers are covered by the European Commission's standard contractual clauses.

If you pick a language in the language menu, that choice is saved in your browser (local storage) so the site shows up in that language on your next visit. It is never sent to us or to anyone else, and you can erase it by clearing this site's data in your browser.

Your rights

Under the GDPR, you have the right of access, rectification, erasure, restriction, objection and portability. Since your collections stay on your device, you control them directly: deleting them from the app or uninstalling the app erases them. For any question, write to the address above. You can also lodge a complaint with the CNIL (cnil.fr), the French data protection authority.

Changes

When the online features (account, cloud backup, sharing) arrive, they will be optional, and this policy will be updated before their launch to describe precisely the data involved.
