Privacy policy

Effective 10 November 2026. This English version is a translation; the French version prevails.

1. In short

• Metalary works with no account, no ads, no tracking and no audience analytics.
• Your jobs, calculations, photos and backups are stored on your device. The Level Code does not receive them.
• Purchases are handled by Apple or Google: we receive no payment data.

2. Data controller

The Level Code, SASU, 266 rue Nationale, 59800 Lille, France, SIREN 106 997 059. Contact: contact@metalary.app.

3. Data stored on your device

3.1. The app stores in its local storage, on your device: your settings, calculation history, jobs (name, client, site, reference), ISO plans, weld log, welder records (name, stamp, qualifications) and the photos you add. This data is not sent to The Level Code.

3.2. It is erased when you delete it in the app or uninstall the app. Depending on your settings, your system backup (iCloud or Google) may include it; that processing is the responsibility of Apple or Google.

3.3. Backups and exports: the Backup feature creates a .metalary.json file (data and photos), and the app can create PDF and DXF files. These files are created only when you ask, and you choose where to send them (folder, messaging, cloud).

3.4. If you store data about other people (for example your welders’ records), you are responsible for it within your business; inform them. The Level Code has no access to it.

4. Permissions

• Camera and photos: only when you add a photo to a job or a weld.
• Accelerometer: for the tilt measurement tool, on the device.

The app does not ask for location, contacts or microphone.

5. Network connections

The app does not contact any server of The Level Code. It only connects in these cases:

• Apple’s or Google’s purchase system contacts their servers when you view the offers, buy, restore a purchase, or when the app checks the status of Metalary Pro. The app then only receives the status of your purchases (product, active or not, end date), which it keeps on the device;
• when you tap a link (source of a value, page of this website, store subscriptions page), it opens in your browser.

6. Purchases

Purchases are handled by Apple (App Store) or Google (Google Play) under their own privacy policies. The Level Code receives neither your name, nor your email address, nor your payment data. Apple and Google give publishers sales reports and statistics (downloads, crashes); usage and crash statistics depend on the consent you gave in your device settings.

7. The metalary.app website

The website uses no cookies, no tracking and no audience analytics. It is hosted by Cloudflare, which processes technical connection data (including the IP address) to serve the pages and protect the site from attacks. The Level Code keeps no visit logs.

8. Messages sent to support

If you write to us, we use your email address and message to reply (legal basis: our legitimate interest in answering requests, or performance of the contract for a purchase-related request). Messages are kept for three years after the last exchange, then deleted. Our mailbox is hosted by Google (Google Workspace).

9. Recipients and transfers

Only our technical providers process data on our behalf: Cloudflare (website hosting) and Google (email). These US companies may process data in the United States; they participate in the EU–US Data Privacy Framework, recognised by the European Commission’s adequacy decision of 10 July 2023. We sell no data.

10. Your rights

10.1. You have the rights of access, rectification, erasure, restriction, objection and portability over the data we hold, that is, your messages. Write to contact@metalary.app; we reply within one month.

10.2. The app’s data is on your device: you view, export and delete it yourself in the app.

10.3. You may lodge a complaint with the CNIL (French data protection authority), 3 place de Fontenoy, TSA 80715, 75334 Paris Cedex 07, France, www.cnil.fr, or with the authority of your country.

11. Changes

This policy is updated if the app or its processing changes. The version in force is published on this page with its date.
