Milk First is built to be private by default. Here's the short version: your milk-tracking data lives on your device, and we don't collect it.
Your tracking data: nothing. Milk First does not require an account. Pump sessions, stash inventory, amounts, dates, locations, notes, and settings are stored locally on your device only — none of it is ever sent to us.
What we do collect is a small amount of anonymous usage and purchase information, described below, so we can tell whether the app works and gets better.
The app sends a few anonymous signals — for example "a pump was logged" or "the upgrade screen was shown" — through TelemetryDeck, a privacy-first analytics service that processes data in the EU and cannot identify you. These signals never include your actual data: no amounts, no dates, no names, no notes. They tell us that a feature was used, never what you recorded.
Subscriptions are processed by Apple through the App Store. We never see your payment details. To make subscriptions work reliably (free trials, renewals, restoring purchases) we use RevenueCat, which receives anonymized transaction information from Apple — a random identifier and subscription status, never your name, Apple ID, or payment details. Apple's privacy policy governs the transaction itself.
Pump and expiry reminders are local notifications scheduled on your device. They never leave your phone.
When you export a CSV or PDF, the file is generated on your device and shared only where you choose to send it.
Deleting the app deletes your data. There is no copy of your tracking data on our side to delete. Anonymous analytics signals can't be traced back to you, which also means there's nothing identifiable to delete.
Milk First is intended for adults (parents and caregivers). It does not knowingly collect information from children.
If we ever change how data is handled (for example, adding optional iCloud sync), we'll update this policy and describe the change plainly in the app before anything happens.
