Last updated: 24/03/2026

This privacy policy describes how z0057393 (hereinafter "the Publisher") collects, uses, and protects data when you use the Milky mobile application (hereinafter "the App"). The App does not require account creation and does not collect any directly identifiable personal data. It integrates third-party services (Google AdMob, RevenueCat, PostHog) for advertising, subscription management, and product analytics.

1. App Publisher

The Milky App is published by z0057393. For any questions regarding the protection of your data, contact us at: ncboissel@gmail.com.

2.1 Data Stored Locally on Your Device

All data related to your breast milk tracking (quantities, dates, storage types, history) is stored exclusively on your device. This data is never transmitted to our servers. The App does not require account creation or any personal identifier such as an email address, name, or phone number.

2.2 Data Collected via Google AdMob

The App integrates Google AdMob (Google LLC) to display advertisements. AdMob may collect the following data:

  • Advertising identifier (IDFA — Identifier for Advertisers), if you have granted consent via the ATT prompt
  • Ad interaction data (impressions, clicks)
  • Ad performance data
  • General device information (model, operating system, iOS version)
  • Approximate location (country or region, derived from IP address)
  • Behavioral data for personalized advertising (only if ATT consent is granted)

2.3 Data Collected via RevenueCat

The App integrates RevenueCat (RevenueCat Inc.) to manage subscriptions and in-app purchases. RevenueCat may collect the following data:

  • Anonymous user identifier (automatically generated by RevenueCat, with no link to your real identity)
  • Status and history of your subscriptions and in-app purchases
  • Transaction data (dates, subscription type)

2.4 Data Collected via PostHog

The App integrates PostHog (PostHog Inc.) for user behavior analysis and product improvement. PostHog may collect the following data:

  • Anonymous user identifier (automatically generated, with no link to your real identity)

2.5 Technical Data

The App also collects anonymous technical data to ensure proper functioning:

  • Diagnostic and crash data (anonymous crash reports)
  • App performance data

None of this data is linked to your real identity. The App does not directly access your GPS location, contacts, or photos. The approximate location collected by AdMob is derived from your IP address.

3. Purpose of Processing

Data collected through our third-party services is used for the following purposes:

  • Displaying personalized advertisements (if ATT consent granted) or non-personalized ads (via Google AdMob)
  • Managing and validating your subscriptions and in-app purchases (via RevenueCat)
  • Analyzing user behavior to improve the App (via PostHog)
  • Detection, diagnosis, and correction of crashes and bugs
  • Improving App performance and stability
  • Personalizing the advertising experience if ATT consent is granted

4. Legal Basis for Processing (GDPR)

The processing of data described in this policy is based on the following legal grounds:

  • Legitimate interest (Article 6.1.f of the GDPR): anonymous usage analysis via PostHog, display of non-personalized advertising, and App improvement
  • Performance of a contract (Article 6.1.b of the GDPR): management of your subscriptions and in-app purchases via RevenueCat
  • Consent (Article 6.1.a of the GDPR): display of personalized advertisements via Google AdMob, subject to your agreement via the ATT (App Tracking Transparency) prompt

5. Tracking & Advertising (ATT)

The App uses Apple's App Tracking Transparency (ATT) framework to request your consent before any personalized advertising tracking via your IDFA (Advertising Identifier):

  • On first launch, an ATT prompt asks whether you allow the App to access your IDFA
  • If you accept, Google AdMob may use your IDFA to display personalized advertisements based on your profile
  • If you decline, only non-personalized (contextual) advertisements will be shown to you
  • You can change your choice at any time in Settings > Privacy & Security > Tracking
  • We do not engage in cross-app tracking and we never sell your data to third parties

6. Data Sharing with Third Parties

Data collected through our integrated services is transmitted exclusively to the following providers, acting as data processors:

  • Google LLC (AdMob) — personalized or non-personalized ad display. Privacy policy: policies.google.com/privacy
  • RevenueCat Inc. — subscription and in-app purchase management. Privacy policy: www.revenuecat.com/privacy
  • PostHog Inc. — user behavior analytics. Privacy policy: posthog.com/privacy
  • Apple Inc. — payment processing and in-app purchase validation via the App Store. Payments are handled directly by Apple and do not transit through our systems

None of your data is sold to third parties. These providers are subject to their own privacy policies and are GDPR-compliant.
