In short: Otonagi does not collect, store or share any of your personal data.
There is no account, no server, no ads, no analytics and no tracking. What you enter in the app stays on your iPhone.
This policy explains how the Otonagi app for iPhone ("Otonagi", "the app") handles information. Otonagi is made by Magnus Cederberg, Sweden ("we", "us").
What stays on your device
Some features let you enter or create information. All of it is saved only on your iPhone, inside the app's own storage. We never receive it and cannot see it.
- Your name, if you choose to give one, so the app can greet you.
- Daily check-ins ("How are you today?"), if you use them: the day and the feeling you chose. The app keeps your last 60 check-ins so it can show how your days have been.
- Feeling check-ins ("How do you feel now?") after Breathe, after Ugoki (the guided movement in Kumo), after Hogushi (the stretching guide in Nobi), after Himukae (the sun salutation in Hinode), or after a long listening session, if you answer them: the time, what you had just done, and the one or two feelings you picked. The app keeps your last 120 answers.
- Your own moods, if you save any with Otonagi Plus: each one's name, the mood it is made from, its sliders, style and nature levels, and which one played last.
- Today's word: which words you have already seen, so each word comes once before any repeats.
- Settings such as your chosen mood, style, sound mix, the sliders for each mood, the Music and Tapping volumes, breathing pattern and timer, and small counters (for example, how often the app has been opened) that decide when to show a tip or the Otonagi Plus screen, and whether the first-start tour is still to come.
- Purchase status, so the app knows whether Otonagi Plus is unlocked. This comes from Apple and is checked on your device.
Check-ins are only for you. They are not shared with Apple Health, are never sent anywhere, and nobody else can see them, including us.
If your iPhone is backed up to iCloud or a computer, this information may be included in that backup, which is handled by Apple under its own privacy policy. You can erase all of it at any time by deleting the app.
Apple Health
If you choose to connect Apple Health, Otonagi can save four things to the Health app. Each is off by default and turned on separately, in its guide's sheet or in the Apple Health section of the app's menu, and only sessions of a minute or more are saved:
- Mindful minutes from finished Breathe sessions.
- Tai Chi workouts from Ugoki sessions in Kumo.
- Flexibility workouts from Hogushi stretching sessions in Nobi.
- Yoga workouts from Himukae sun salutation rounds in Hinode.
That is all it does. Otonagi only writes these and never reads any of your health data. This information goes from Otonagi straight into Health on your iPhone and is never sent to us or anyone else. Health data is not used for advertising or any other purpose.
You can stop this at any time in the Health app (Sharing › Apps › Otonagi) or in your iPhone's Settings › Privacy & Security › Health.
Notifications
Otonagi only sends notifications if you allow them, and every one is scheduled on your iPhone itself. No server is involved and nothing about them is sent to us. There are two kinds:
- Trial reminder: if you start the monthly plan's free week, a note two days before it ends, between 09:00 and 21:00. It is removed if you cancel the free week or buy Plus another way.
- Check-in after a long session: about 15 minutes after you stop listening to a session of 30 minutes or more, a gentle "How do you feel now?". Never after the sleep timer, never between 22:00 and 08:00, and at most once a day. You can turn it off in the app's menu under Check-ins.
You can turn off all notifications from Otonagi in Settings › Notifications › Otonagi.
Siri, Shortcuts and the Lock Screen
If you use Siri or Shortcuts with Otonagi (for example "Play Otonagi" or "Move with Otonagi"), Apple handles your voice request under its own privacy policy and only passes the action to the app. The sleep timer's Live Activity and the Lock Screen controls show the current mood and time on your iPhone only.
What we do not collect
Otonagi does not collect or send anywhere: your name, contact details, location, health information, usage data, identifiers or device information. It contains no third-party analytics, advertising or tracking code, and it does not track you across other apps or websites.
Otonagi does not ask for access to your microphone, camera, contacts, location or photos. The only permissions it may ask for are Apple Health (to write mindful minutes and tai chi, flexibility and yoga workouts) and notifications (for the trial reminder and the check-in after long sessions), and both are optional.
Purchases
Subscriptions and one-time purchases are handled entirely by Apple through the App Store. We do not receive your payment details, Apple ID or billing address. Apple's handling of this information is described in Apple's Privacy Policy.
Information Apple may share with us
If you have agreed in your iPhone's settings to share analytics or crash reports with app developers, Apple may give us anonymous, combined statistics (for example, the number of downloads or crashes). This information does not identify you, and we only use it to improve the app.
When you contact us
If you email us for support, we receive your email address and whatever you write. We use it only to reply to you, do not share it, and delete the conversation when it is no longer needed. Our email is provided by Google (Gmail), so your message is also handled under Google's Privacy Policy.
This website
This website is hosted on GitHub Pages. It uses no cookies, analytics or tracking, and loads nothing from other services. GitHub may log technical information such as IP addresses to run and secure its service, as described in GitHub's Privacy Statement.
Children
Otonagi is suitable for all ages. Because the app collects no personal data, it collects none from children.
Your rights
Depending on where you live, laws such as the EU General Data Protection Regulation (GDPR) or the California Consumer Privacy Act (CCPA) give you rights over your personal data, such as access and deletion. Since we hold no personal data from the app, there is nothing for us to give you or delete; the information in the app is in your hands and you can delete it by deleting the app. For anything you have sent us by email, contact us and we will help.
Changes
If this policy changes, we will update it on this page and change the date above. If a change ever meant collecting data, we would ask for your permission in the app first.
