Privacy policy

Who we are

Luba is an iPhone app that suggests meals for each phase of the menstrual cycle. In this policy, "Luba", "we" and "us" mean the operator of the app and of this website. You can reach us at support@luba.health.

What the app stores, and where

To work, Luba saves the information you choose to enter. It is stored in the app's own storage on your iPhone:

• Your cycle settings and the dates of your periods, and the flow you log
• Symptoms and "feeling good" check-ins
• Health conditions, diet and allergy choices you select during setup (used to filter recipes and show safety notes)
• Meals you mark as eaten, water, saved recipes, your meal plan, grocery list and the ingredients in your kitchen
• Your reminder and notification settings

This information never leaves your iPhone on its way to us. All the recommendations, predictions and insights are worked out on your phone; Luba has no server that receives your data and works without an internet connection.

If you use iCloud Backup or back up your iPhone to a computer, Apple includes app data, including Luba's, in that backup. Those backups are controlled by you and Apple, and we cannot access them.

What we don't do

• We don't collect personal information or health information. There is no account and no sign-up.
• We don't sell, rent, share or disclose your data, including consumer health data, to anyone.
• We don't use advertising, analytics, crash-reporting or tracking tools, and we don't track you across apps or websites.
• We don't use your data to train AI models or for any purpose other than showing it back to you in the app.

Notifications

Reminders, such as "Period due in 2 days", are scheduled on your iPhone by the app itself. Nothing is sent from a server. You can turn each reminder off, and "Discreet notifications" (in Reminders) hides what a notification is about on your lock screen.

Files you create

Luba can create a backup file, a spreadsheet of your logs and a doctor report. These files are made on your phone and go only where you send them, for example to Files, iCloud Drive, email or a printer. Keep them somewhere safe: they contain your health information.

Your choices and deleting your data

• See and export: Settings → Your data → Download backup or Export CSV.
• Delete everything: Settings → Reset and set up again, or delete the app. Deleting the app removes all of its data from your iPhone.
• Notifications: turn them off in the app's Reminders, or in iPhone Settings → Apps → Luba → Notifications.

Because we don't hold any of your data, there is nothing for us to access, correct or delete on our side. If you have questions about your rights under the laws where you live, write to us and we'll help.

This website

luba.health uses no cookies, analytics or trackers, and loads nothing from other sites. Like any website, our hosting provider may keep standard server logs (such as IP address and pages requested) for a short time to keep the site secure and running.

Children

Luba is not directed to children under 13, and we do not knowingly collect information from anyone.

Changes to this policy

If we change how Luba handles data, we'll update this page and the date at the top, and explain significant changes in the app's release notes. If Luba ever adds an optional feature that sends data off your phone (such as sync between devices), we'll ask for your permission first and describe it here before it ships.
