Frequently Asked Questions

That's the whole idea. Research shows that trying to change too many habits at once leads to failure. Just3 Habits limits you to 3 so you focus on what truly matters — and actually finish every day.
Yes! Go to Settings → More Slots and watch a short reward ad to unlock an additional slot. You can repeat this to unlock further slots one at a time.
Your streak counts consecutive days on which you checked off the habit. If you miss a day, the streak resets to 0. Check off your habits every day to keep the chain alive!
Go to Settings, tap a habit name, and set a reminder time. The app will send you a notification at that time each day. Make sure to allow notifications when prompted.
Go to Settings → Habits, then swipe left on the habit you want to delete and tap "Delete". Note: deleting a habit permanently removes its streak history.
Yes, Just3 Habits is completely free to download and use. A small banner ad appears at the bottom of the home screen, and an occasional ad plays when you complete all your habits for the day.
Unfortunately, habit data is stored locally on your device and is not backed up to iCloud or any server. Uninstalling the app permanently removes all data. We recommend not uninstalling unless necessary.

How We Handle Your Data

Last updated: July 17, 2026

Overview

Just3 Habits ("the app") is developed by Hiroaki Tajima. We are committed to protecting your privacy. This policy explains what data is collected and how it is used.

Data We Do Not Collect

The app itself does not collect, store, or transmit any personal information. All habit data (names, streaks, notification times) is stored locally on your device only and never sent to any server.

Advertising (Google AdMob)

Just3 Habits uses Google AdMob to display ads. AdMob may collect and use the following data to serve personalized or contextual ads:

  • Device advertising identifier (IDFA)
  • IP address and approximate location
  • Usage data and interaction with ads
  • Device information (model, OS version)

For more information on how Google uses this data, please see Google's Privacy Policy: https://policies.google.com/privacy

App Tracking Transparency

On iOS 14 and later, the app will ask for your permission before accessing the advertising identifier for personalized ads. You can change this permission at any time in your device's Settings → Privacy & Security → Tracking.

Data Retention

Since all habit data is stored locally on your device, you can delete it at any time by uninstalling the app. We do not retain any data on external servers.

Children's Privacy

Just3 Habits is not directed at children under 13. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated date.
