Privacy Policy

Last updated: July 6, 2026

Mumly ("the app") is made by Aidelly Corporation ("we", "us"). This policy explains what data the app handles, where it lives, and the choices you have. The short version: Mumly works without an account, and your personal health data is stored on your device.

Information stored on your device

Everything you enter in Mumly is stored locally on your iPhone and is not transmitted to us:

• Your profile and preferences (stage of motherhood, food and movement preferences, schedules, goals)
• Water, meal, mood, and workout logs
• Menstrual cycle data — period dates, flow, symptoms, and the estimates computed from them
• Saved favorites

We cannot access this data. Deleting the app deletes it. You can also erase everything at any time from Settings → Reset.

Information processed by service providers

Purchases. Subscriptions are processed by Apple and by RevenueCat, our subscription-management provider. RevenueCat receives your purchase history and a random anonymous identifier so your subscription unlocks correctly across reinstalls. This identifier is not linked to your name, email, or any personal profile — Mumly has no accounts. See RevenueCat's privacy policy.

Apple. Payment is handled entirely by the App Store under Apple's privacy policy. We never see your payment details.

What we don't do

• No advertising, and no sale of data — ever
• No tracking across other apps or websites
• No analytics SDKs collecting your behavior in this version of the app
• No account, email, or sign-up required

Website waitlist

If you join the launch waitlist on trymumly.com, we store the email address you provide, solely to tell you when the app is available. We won't add you to any other list or share the address, and you can request its deletion anytime at support@aidelly.com.

Notifications

If you allow notifications, reminders are scheduled locally on your device. Their timing may be derived from data you entered (for example, an estimated period date), but that computation happens on-device and nothing is sent to us.

Future features

We may introduce optional features that require data to leave your device — such as cloud backup, sync across devices, or accounts. If we do, they will be opt-in, clearly explained before you enable them, and this policy will be updated first. Nothing will start syncing silently.

Children

Mumly is intended for adults and is not directed at children under 13. We do not knowingly collect personal information from children.

Your rights

Because your data lives on your device, you are in direct control of it: view it in the app, delete individual entries, or erase everything via Settings → Reset (or by deleting the app). For purchase data held by RevenueCat or Apple, you can contact us and we will help you exercise your rights (access, deletion) with those providers.

Changes to this policy

If we change this policy, we will update the date above and, for material changes, note it in the app's release notes.
