Terms

Using Balancier, subscribing to Balancier+

In short: Balancier is free; Balancier+ costs €3.99 a month or €29.99 a year, with seven days free, and can be canceled at any time.

1. The publisher

Balancier (balancier.app and the Balancier app) is published by Matthieu Cassier, 23 rue du Docteur Émile Roux, 92150 Suresnes, France. Contact: contact@balancier.app. The site is hosted by Netlify, Inc., 512 2nd Street, San Francisco, CA 94107, United States.

2. Balancier, free

Finding a watch, keeping a collection (three watches) and a wishlist (three watches), the daily ritual, the museum of icons, the news feed: all of this is free, with or without an account. Some features that cost money each time they are used (AI-powered full searches and scans, listing alerts, price lookups) have a free limit, stated where it applies.

3. Balancier+

Balancier+ is a subscription. In the iPhone app you can buy it without creating an account, and it then works on that iPhone; with a Balancier account (optional) you get it on your other devices and on the web, where an account is needed to subscribe. It adds:

• all your watches : your collection and your wishlist with no limit (a list that was already longer before subscribing is never cut down: you simply can't add to it without Balancier+);
• your collection's market value refreshed every week, and an alert when a watch gains or loses 5%;
• daily alerts for fifteen watches on your wishlist (three without a subscription) and “deals” below market value;
• thirty full searches and scans a month (three without a subscription);
• the insurance file for your whole collection, in one PDF;
• reminders before your watches' services and warranty end dates;
• “Your year in watches”, eight photos per watch, exporting your collection, the ✦ badge and the app icons.

The limits above protect the service from automated use; they may change, but never so as to reduce what is included during a period already paid for.

4. Price

€3.99 a month or €29.99 a year, all taxes included for France. In the app, the price is the one the App Store shows in your currency; it may vary from one country to another.

5. The free trial

New subscribers get seven days free, once per subscriber. If you don't cancel at least 24 hours before the trial ends, the subscription starts and the first period is charged.

6. Payment, renewal, cancellation

• In the iPhone app, payment goes through your Apple account. The subscription renews automatically at the end of each period, unless canceled at least 24 hours before. You manage and cancel it in Settings › your name › Subscriptions.
• On the web, payment goes through Stripe, via RevenueCat. The subscription renews automatically; you cancel it with the management link in your confirmation email, or from My account › Balancier+ › Manage my subscription.

A cancellation takes effect at the end of the current period: Balancier+ stays active until then, with no refund for the period already started, except where provided by law.

7. Right of withdrawal

You have fourteen days from subscribing to withdraw, without giving a reason. By asking for Balancier+ to start right away, you agree, if you withdraw, to pay for the part of the service already provided. For a purchase made on the web, write to contact@balancier.app ; for a purchase made in the app, the refund is requested from Apple, which collected the payment (reportaproblem.apple.com).

8. What the figures are worth

The market values and prices shown come from listings and offers published online: they are asking prices, a ballpark figure. They are not an appraisal, an insurer's valuation, or advice to buy, sell or invest. The watch profiles and stories are carefully written from cited sources; a mistake may still slip in — report it to contact@balancier.app.

9. Your account

You are responsible for what you publish (showcase, photos). The publisher may suspend an account in case of obvious abuse (automated use, unlawful content); an ongoing subscription is then refunded pro rata, except in case of fraud. You can delete your account at any time; a subscription is canceled separately, with Apple or through the management link.

10. Availability

Balancier relies on third-party services (search engines, listings, artificial intelligence) that may be temporarily unavailable. The publisher does its best to keep the service running, but cannot guarantee it at every moment.

11. Disputes

These terms are governed by French law. In case of a dispute, write first to contact@balancier.app. You can also turn, free of charge, to the consumer mediator: [mediator's name and address]. The European online dispute resolution platform is available at ec.europa.eu/consumers/odr.

What Balancier keeps about you is described on the Privacy.
