Privacy

Kyro has no account and no server of its own, so there is nothing for me to collect.

What Kyro stores

Your habits, your completions, your streaks and your scores are stored on your device. Delete the app and that copy goes with it.

Kyro also syncs the same data to your own private iCloud database, under your Apple Account, whenever you are signed in to iCloud.

What Kyro sends

Nothing to me. Kyro contains no analytics, no advertising and no third-party tracking, not even anonymous or aggregated counts, and there is no server of mine it could send anything to.

If you use the watch, the operating system passes your habits straight between your iPhone and your Apple Watch.

Apple gives every developer aggregate App Store figures such as installs and crash counts. Those come from Apple and are produced without the app sending anything.

Apple Health

Kyro reads Apple Health data only if you link a habit to a Health goal, and only the kinds of data that habit needs. Reading happens on your device.

The one thing Kyro writes to Health is water you log yourself on a water-linked habit. Everything else is read-only.

Raw Health values never leave your device and never enter the synced database. What syncs is whether the habit was completed, and nothing else.

Reminders

The daily reminder is off until you switch it on. Switching it on asks for permission to send notifications, or to set alarms if you choose Alarm. It is scheduled on your iPhone and sends nothing to me.

Apart from the reminder, Kyro shows one notification shortly before the free trial ends, and only if you have already allowed notifications.

The trial and the subscription

The free trial runs in the app itself. So that it starts when you first open Kyro and does not start over when you reinstall, the app keeps a few dates on your device and in your own iCloud: when you first opened it, when your trial began and, once you subscribe, until when your subscription runs. Apple provides one more, the date your Apple Account first got Kyro. None of these reach me.

The subscription is handled by Apple. No payment details reach me, and the app never sees a card number.

Deleting your data

Deleting a habit deletes its history. Deleting the app removes only the copy on that device. To remove everything, including the synced copy in your iCloud, use Remove All Data in Settings.

You can also export everything to a file first, from Settings. That file is yours, and it works whether or not you have paid.

This website

This site is hosted by Cloudflare, which processes the IP address of every visitor in order to serve the page and to protect the site from attack. That is the legitimate interest basis in Article 6(1)(f) GDPR, and it can involve a transfer to the United States under Cloudflare’s standard contractual clauses.

There are no cookies, no analytics and no third-party scripts on any page here.

Your rights

The GDPR gives you rights of access, correction, erasure, restriction, objection and portability, and the right to complain to a data protection authority. Because your habit data never reaches me, most of these are things you exercise on your own device rather than by asking me.
