Privacy Policy

Last updated: 10 October 2026

Arbitre Météo BTP helps construction tradespeople decide whether the weather allows work on their jobsites. This page explains what data the app uses, why, and how to delete it.

Data controller

Romaric Heitz, publisher of the app. Contact: [email protected].

What we do not collect

Your phone’s location: the app does not ask for it. Only the jobsite addresses you enter are used.
Your contacts, or any data for advertising.
No tracking or audience measurement tools.

Data used and purposes

Data	Why
Internal account identifier, account type, display name	To run your account. You can start without creating a named account.
Email address and identifier provided by “Sign in with Apple” (Apple may provide a relay address)	To secure your account and restore it on another phone.
Trade, language, time zone, notification preferences, custom thresholds	To compute verdicts suited to your trade and notify you as you choose.
Jobsites: name, address, geographic coordinates, status, settings	To get the weather forecast for the location and compute each site’s verdict.
Jobsite photos (if you add any)	To illustrate your sites. Photo access is only requested when you add one.
Recorded decisions, comments, alerts received	To keep each site’s history.
Phone notification token, platform, language	To send you alerts, only if you turn them on.
Server technical logs (IP address, date, request)	Security and incident diagnosis.

Legal bases: performance of the service you use, your consent for notifications and photo access, and our legitimate interest in keeping the service secure.

Service providers

OVH SAS (France): server and database hosting.
Cloudflare: secure traffic routing and storage of jobsite photos.
Apple: “Sign in with Apple”, and weather forecasts (Apple Weather), which receive jobsite coordinates without your identity.
Expo (650 Industries), then Apple or Google: delivery of notifications to your phone.
IGN – Géoplateforme (France): address search, from the text you type.

Some of these providers are based outside the European Union, notably in the United States. These transfers rely on the GDPR safeguards offered by these providers. Your data is never sold.

Retention

Account and jobsite data: as long as your account exists.
Computed forecasts and verdicts: automatically deleted after 30 days, except those linked to a decision you recorded, which stay in the site history.
Sign-in sessions: 90 days at most.

Deleting your account

In the app: Account › My profile › Delete my account. Deletion is immediate and permanent: account, sites, photos, history and notification tokens are erased, and the “Sign in with Apple” authorisation is revoked. Only an anonymous record that an account was deleted remains. You can also ask by email.

Your rights

You have the rights of access, rectification, erasure, restriction, objection and portability. Write to us at the address above. You may also lodge a complaint with the French data protection authority, CNIL (cnil.fr).

Security

Traffic is encrypted (HTTPS). Your sign-in tokens are kept in the phone’s secure keychain. Photos are only reachable through temporary links.

Changes

Any significant change to this policy will be announced in the app. The update date is shown at the top of this page.
