Terms of use and sale
Effective 10 November 2026. This English version is a translation; the French version prevails.
1. Purpose
These terms govern the use of the Metalary mobile app (iOS and Android) and the purchase of Metalary Pro. The app is published by The Level Code, SASU, 266 rue Nationale, 59800 Lille, France, SIREN 106 997 059 (see the legal notice). Contact: contact@metalary.app.
Purchases are made through Apple’s App Store or Google Play, whose terms also apply to payment. On iOS, Apple’s standard Licensed Application End User License Agreement applies; these terms supplement it.
2. The app
2.1. Metalary provides shop-floor calculations (piping, welding, fabrication, machining), technical references and job tracking tools. Everyday tools are free. Metalary Pro unlocks the features described on the Metalary Pro screen of the app.
2.2. The app works without an account and offline. Your data stays on your device (see the privacy policy). You make your own backups with the app’s Backup feature: without a backup, losing the device or uninstalling the app erases this data.
3. Metalary Pro offers
3.1. Pro yearly and Pro monthly: automatically renewing subscriptions lasting one year or one month.
3.2. Free trial: the Pro yearly and Pro monthly subscriptions start with a 7-day free trial. The trial is granted once, under the App Store or Google Play rules; the purchase screen shows whether it is offered to you. At the end of the trial the subscription becomes paid, unless cancelled at least 24 hours before the trial ends.
3.3. Lifetime access: a one-time payment, with no subscription or renewal. It unlocks Metalary Pro with no time limit, for the Apple or Google account used for the purchase.
3.4. Prices: prices, currency and taxes are those shown by the App Store or Google Play at the time of purchase and confirmed on their payment screen.
4. Renewal and cancellation
4.1. The subscription renews automatically for the same length, at the price then shown by the store, unless cancelled at least 24 hours before the end of the current period. The renewal is charged within the 24 hours before the end of the period.
4.2. You cancel in the store settings: on iPhone, Settings, your name, Subscriptions; on Android, Google Play, Payments and subscriptions, Subscriptions. The steps are on the Help page. Uninstalling the app does not cancel the subscription.
4.3. Cancellation takes effect at the end of the period already paid: Metalary Pro stays active until then, after which the app returns to the free features. Your data stays on the device.
4.4. If a subscription price goes up, the store informs you in advance under its rules; you can cancel before the new price applies.
5. Payment and refunds
5.1. Payment is collected by Apple or Google under their terms. The Level Code receives no payment data.
5.2. Refund requests go to Apple (reportaproblem.apple.com) or Google Play, which handle them under their terms. The Level Code does not collect the payment and therefore cannot refund it directly.
5.3. On a new device linked to the same account, the app’s Restore purchases feature brings back Metalary Pro with no new payment.
6. Right of withdrawal
6.1. Consumers normally have 14 days from the conclusion of the contract to withdraw, without giving a reason (article L221-18 of the French Consumer Code).
6.2. Withdrawal is exercised within these 14 days with Apple or Google, which collect the payment, or by writing to contact@metalary.app. The free trial can be cancelled at any time at no cost (section 3.2).
7. Legal guarantee of conformity
Consumers benefit from the legal guarantee of conformity for digital content and services (articles L224-25-12 et seq. of the French Consumer Code), under the conditions and time limits of those articles. Report any defect to contact@metalary.app.
8. Indicative results and liability
8.1. Metalary gives indicative values to prepare the work. They replace neither the applicable standards, nor a qualified WPS or procedure, nor the job drawings and instructions. Always check a dimension before cutting and have welding parameters approved by the person in charge.
8.2. Users check the values they enter and the results before any execution (marking out, cutting, welding, machining, commissioning). They alone decide how to use them.
8.3. Business users: to the extent permitted by law, The Level Code is liable neither for indirect damage (loss of production, material or revenue) nor for damage resulting from the use of an unchecked result. Its liability is limited to the amount paid for Metalary Pro in the twelve months before the event giving rise to it.
8.4. Consumers: The Level Code is liable for damage under ordinary law. Nothing in these terms limits the rights consumers have under the law.
8.5. No limitation applies in case of gross negligence or wilful misconduct, or of personal injury.
9. Licence and intellectual property
The Level Code grants you a personal, non-exclusive right to use the app. The app, its texts, drawings, name and logo belong to The Level Code. You may not copy, modify or redistribute them, except where the law allows it (article L122-6-1 of the French Intellectual Property Code).
10. Personal data
See the privacy policy.
11. Changes to these terms
The Level Code may change these terms, in particular to follow changes in the app or the law. The version in force is published on this page with its date. A change does not apply to a subscription period already paid.
12. Governing law, complaints and mediation
12.1. These terms are governed by French law. Consumers living in another country keep the protection of the mandatory rules of their country.
12.2. Any complaint is first sent in writing to contact@metalary.app.
12.3. Every consumer has the right to use a consumer mediator free of charge to settle a dispute amicably (article L612-1 of the French Consumer Code), after sending a written complaint to The Level Code.
12.4. Failing an amicable settlement, the dispute is brought before the competent courts. Between businesses, the courts of Lille have sole jurisdiction.
