Terms of use and sale

Last updated: 21 September 2026

1. Purpose

These terms govern the use of the Estimation Objet mobile app (the "App") and, where applicable, the subscriptions offered within it. From photographs taken by the user, the App provides an indicative estimate of what an object is worth, together with information about its likely period, condition, rarity, apparent authenticity, comparable sales and selling platforms.

The App is an information and decision-support tool. It is neither an appraisal service, nor a valuation service within the meaning of the rules applicable to voluntary auction sales, nor a marketplace: the publisher neither buys, nor sells, nor brokers any transaction.

2. Publisher

The App is published by BAUGEY MATHEO, trading as DEVOLIM, 248 rue de Bègles, 33800 Bordeaux, France, SIREN 948 000 757. Contact: contact.estimationobjet@devolim.fr. The legal notice supplements these terms.

3. Acceptance

Downloading, installing or using the App constitutes full acceptance of these terms, which are available at any time from within the App and from this website. Users who do not accept them must refrain from using the App and uninstall it.

The App is intended for adults or, failing that, for minors acting with the authorisation of their legal guardian.

4. Access to the service

The App requires a compatible device, an up-to-date operating system and an internet connection to start an estimate, talk to Filou or write a listing. Connection and hardware costs remain the user's responsibility. Browsing an inventory that has already been built remains possible offline.

The App is free to use in its basic version, within a number of free estimates shown in the App. The publisher may change that number, in particular to reflect the actual cost of the analyses, which does not amount to a change of contract for existing subscribers.

The publisher endeavours to keep the service available but cannot guarantee permanent availability: an interruption may result from maintenance, from the failure of a technical provider, from force majeure or from a decision to suspend the service temporarily. Technical usage limits (number of analyses per day, per hour and per installation) are applied to protect the service against abuse.

5. No user account

The App has no user account: no sign-up, no username, no password. An anonymous technical identifier is created automatically at first launch so that the service can work and free estimates can be counted. It is not an account and gives access to no online personal space.

As a result, the data created in the App exists only on the device. Loss, theft, reset of the device or uninstallation of the App lead to the permanent loss of that data, unless a backup of the phone is restored. We recommend enabling your device backup and using the export function available in the settings.

6. Permitted use

Users undertake to use the App in accordance with its purpose and with the law. The following are prohibited in particular:

• circumventing, attempting to circumvent or automating the usage limits, quotas or attestation mechanisms of the App;
• accessing the service by any means other than the official App, in particular through a script, a repurposed emulator or a modified version;
• systematically extracting, reproducing or reusing the estimates produced, with a view to building a database or a competing service;
• decompiling, disassembling or reverse engineering the App, save in the cases provided for by Article L.122-6-1 of the French Intellectual Property Code;
• transmitting photographs that the user has no right to use, or depicting unlawful content, identifiable persons without their consent, or identity documents;
• using the App for any unlawful activity, in particular to value goods whose possession or transfer is prohibited.

In the event of a serious or repeated breach, the publisher may suspend the relevant installation's access to the server functions, without this giving rise to any compensation. If a subscription is running, the period already paid for is refunded pro rata, through the relevant store.

7. Subscription

The App may offer one or more subscriptions, taken out as in-app purchases. Their name, content, duration and price are those presented in the App at the time of purchase, and may change. No description of an offer appearing elsewhere, including on this website, constitutes a contractual commitment.

The quality of the estimates is identical for everyone: a subscription unlocks additional features, it does not improve the answer given.

7.1 Prices

Prices are those displayed in the app at the time of purchase, inclusive of all taxes, in the currency of your store account. They may vary by country and may change; any change is notified by the store before it takes effect.

7.2 Automatic renewal and cancellation

The subscription renews automatically at the end of each period unless cancelled at least 24 hours before it ends. Cancellation is done from your store account:

• iOS: apps.apple.com/account/subscriptions
• Android: play.google.com/store/account/subscriptions

Cancellation takes effect at the end of the current period; paid features remain available until then.

7.3 Right of withdrawal

Consumers normally have fourteen days to withdraw. Under Article L.221-28 13° of the French Consumer Code, this right cannot be exercised for digital content supplied on a non-tangible medium where performance has begun with your prior express consent and your express waiver of that right, which is the case as soon as the subscription is activated.

7.4 Refunds

Payments are collected by Apple or Google. Refund requests are therefore handled by the relevant store: reportaproblem.apple.com for iOS, or Google Play support for Android. The publisher has no technical means of issuing a refund directly.

7.5 Fair use

Subscriptions are intended for personal and reasonable use. Fair use caps, far above normal usage, apply per day, per week and per month in order to prevent automated or large-scale commercial use. An ordinary user is not expected to meet them.

8. Legal guarantee of conformity

Consumers benefit from the legal guarantee of conformity applicable to digital content and services under Articles L.224-25-12 et seq. of the French Consumer Code, for two years from the supply of the digital content.

9. Intellectual property

The App, its code, interface, texts, illustrations, visual identity and its character Filou are protected by intellectual property law and remain the exclusive property of the publisher. These terms grant only a personal, non-exclusive and non-transferable right to use the App for the duration of that use.

Your photographs remain yours. You keep all rights in them. You grant the publisher and its technical processors only the right to reproduce and process them for the sole purpose of the analysis you request, for the duration of that analysis. No other use is made of them, and they are not used to train an artificial intelligence model.

The texts produced by the App (estimate records, listings) are provided for your use, including commercial use in connection with the sale of your object. They are generated automatically: it is for you to read them and check that they infringe no third-party rights and that they describe accurately the object you are offering.

Brands and the names of manufacturers or artists that may appear in a record are cited for information only, to identify or compare an object. Such mentions imply no partnership, no affiliation and no endorsement by their owners, who retain their rights.

10. Nature of the estimate

The estimate is based on the analysis of photographs and on comparison with sales of objects deemed similar. It may be inaccurate, in particular where the object is rare, poorly lit, partly visible, counterfeit or restored, or where few comparable sales exist. The price actually obtained depends on factors the App cannot know: exact condition, provenance, current market, place and manner of sale.

In particular, the estimate is not valid as: an insurance valuation, an estate inventory or division, a tax return, a banking guarantee, a court appraisal, a certificate of authenticity or a certificate of origin. For those purposes, only the opinion of a qualified professional, in particular a judicial officer, an auctioneer or an expert, may be relied upon. The disclaimer sets out those limits.

11. Liability

The App is provided as is. The publisher undertakes to apply reasonable care and diligence to its operation; this is an obligation of means, to the exclusion of any obligation of result as to the accuracy of an estimate.

Users remain solely responsible for their decisions. The publisher cannot be held liable for:

• a sale or purchase price that differs from the estimate displayed;
• a decision to buy, sell, keep, restore or discard an object, taken in the light of an estimate;
• an error of identification, dating or assessment of authenticity;
• the temporary unavailability of the service, the loss of local data, or the content of third-party websites linked to;
• the use made by the user of the generated listing texts.

Nothing in these terms excludes or limits the publisher's liability in the event of wilful misconduct, gross negligence or personal injury, nor does it affect the statutory guarantees available to consumers. Where liability can be incurred, and to the extent permitted by law, the publisher's liability is capped at the amounts actually paid by the user for the subscription during the twelve months preceding the triggering event.

12. Your obligations when selling

Information about selling platforms and about the lawfulness of a sale is provided for guidance only and may be incomplete or out of date. Before selling or shipping an object, it is for the user to check the applicable rules, in particular regarding:

• protected species and regulated materials (ivory, tortoiseshell, taxidermy, CITES);
• weapons, ammunition and similar items;
• cultural goods, antiques and export licences;
• counterfeits, whose sale and possession for sale are criminal offences;
• the obligations of professional sellers, once selling becomes a habitual activity.

As the publisher is party to no transaction, it guarantees neither the lawfulness nor the successful completion of a sale made by the user.

13. Personal data

The processing of personal data is described in the privacy policy, which forms an integral part of these terms.

14. Changes to these terms

The publisher may amend these terms, in particular to reflect legal, technical or functional developments. The applicable version is the one published on this website on the date the App is used, and the last update date appears at the top of this page. Any substantial change is notified within the App; for a subscriber, it takes effect only at the end of the current period, the subscriber being free to cancel before that date if they do not accept it.

15. Complaints and mediation

Any complaint may be sent to contact.estimationobjet@devolim.fr. A reply is given within fifteen working days.

Subscriptions are sold through the App Store or Google Play: the contract of sale is entered into with Apple or Google, which collect the price and have their own complaint and refund procedures. DEVOLIM supplies the application service. A complaint about payment, invoicing or refunds must therefore be addressed to the relevant store; a complaint about how the App works may be sent to us directly, at the address above.

16. Governing law and language

These terms are governed by French law. In the event of a dispute, and failing an amicable settlement, the French courts have jurisdiction. Consumers retain the right to bring proceedings before the courts of their place of residence, and keep the benefit of the mandatory consumer protection rules of their country of residence within the European Union.

These terms were drawn up in French. In the event of any discrepancy between the French version and a translation, the French version prevails.
