How can we help?

Apple manages Inson3 subscriptions, so you cancel from your iPhone Settings:

1. Open Settings and tap your name at the top.
2. Tap Subscriptions.
3. Select Inson3 and tap Cancel Subscription.

You keep Pro until the end of the period you already paid for, and the app stays free and offline after that. During the free trial, we tell you 1–2 days before the first charge, so canceling before then costs you nothing.

Inson3 is local-first: by default, your data stays on your iPhone. iCloud backup is optional and a Pro feature.

When you turn it on, the backup uses your private iCloud (the same account as your Apple ID). Your data never touches Inson3 servers. This lets you restore your history when you switch or reinstall, and sync across your own devices.

You can turn it on or off any time in the app settings, under Backup and sync. Turning it off leaves your data on your iPhone.

Since everything lives on your device, you stay in control:

1. In the app settings, use Delete all data to remove your diary and history from the iPhone right away.
2. If you had turned on iCloud backup, turn it off and remove the app's iCloud data in Settings › [your name] › iCloud › Manage Storage.
3. Deleting the app also removes all of its local data from the device.

We keep no copy of your data on any server of ours, so there's nothing left for us to delete.

No. Inson3 runs fully offline from the first launch, with no login and no account. That's on purpose: at 3am you shouldn't need signal or a password to breathe and fall back asleep.

No. Inson3 is a wellness tool and does not replace advice, diagnosis, or treatment from a health professional. If you have persistent insomnia or another sleep problem, see a doctor.

Inson3 runs on iPhones with a recent version of iOS. The interactive Lock Screen widget and the "I'm awake" Shortcut work on supported models; the Action Button is available on iPhone 15 Pro and later. The app also works with iOS Sleep Focus.
