Privacy Policy — Formidable

Last updated: 10 May 2026 App: Formidable (iOS / Android) Publisher: Jérôme CHRIST Contact: cidauc@gmail.com
Formidable does not collect your personal data. All your wellness data stays on your phone.

1. Data collected by the app

1.1 Data stored locally only

The following data is stored exclusively on your device using AsyncStorage (UserDefaults on iOS, SharedPreferences on Android):

This data is:

1.2 Anonymous technical data (optional)

Two third-party services may be used to improve app quality. They are disabled by default. You can enable or disable each at any time in Settings → Privacy (two separate toggles). Changes take effect immediately, without restarting the app.

Service Data collected Hosting
Sentry (crash reporting) Device type, OS version, app version, error trace. No personal data. No gratitude, mood or intention content is ever transmitted. sentry.io (US / EU)
PostHog (analytics) Anonymous events (e.g. mood_checked_in, breathing_completed), app version, language. No advertising identifier. No fingerprinting. No personal content transmitted. eu.i.posthog.com (Europe)

If the environment variables for these services are not configured (local build, open-source fork), both services are entirely disabled — no network calls are made.

Note for GDPR purposes: Sentry and PostHog act as data processors for anonymous technical data only. No personal data is processed. Data processing agreements (DPAs) are maintained with both providers under GDPR Article 28. Because no personal data is involved, standard contractual clauses are not required.

1.3 Apple Health (optional, iOS only)

If you enable the Apple Health integration in Settings → Apple Health:

All Apple Health data remains on your device.

Annexe A — Version française abrégée

Formidable ne collecte pas tes données personnelles. Toutes tes données de bien-être restent sur ton téléphone. Deux services tiers optionnels (Sentry, PostHog) peuvent collecter des données techniques anonymes si tu les actives dans Réglages → Confidentialité. L'intégration Apple Health est optionnelle et toutes les données restent locales. Pour toute question : cidauc@gmail.com.
