Privacy Policy — Yū Focus

Stored data

All your data (focus statistics, streaks, session history, settings, custom rituals and breathing techniques, sound mix) is stored locally on your devices (your iPhone or iPad, and your Apple Watch if you use it, see below) and shared with the widgets through a local App Group. We run no server to receive it: it is never sent to us.

Apple Watch

If you use the Yū Focus app on an Apple Watch paired with your iPhone, the two apps communicate through WatchConnectivity, the mechanism Apple provides to keep a Watch app in sync with its iPhone app:

• from iPhone to Watch: the current session’s state (ritual, time remaining, playing or paused), your custom rituals, your breathing techniques and, if you use weather, the suggested soundscape (not your location);
• from Watch to iPhone: the results of sessions done on the watch (type, duration, date, completed or interrupted), for your statistics, and pause/resume commands.

These exchanges happen between your devices; Yū Focus does not send them to any server, ours or a third party’s. Their delivery is handled by Apple.

iCloud backup

If iCloud backup is on (“Automatic backup” setting, on by default, can be turned off at any time), a copy of your settings, rituals, custom breathing techniques, statistics and session history is saved to your own iCloud account, so you can get them back after reinstalling or on another device. This copy is stored and delivered by Apple; we have no access to it. It contains neither your location, nor your Health data, nor your purchase information.

Exchanges between Yū Studio apps

Yū Focus can share your completed sessions with Yū Forge and Yū Habits through the “Share my sessions with Yū Habits and Forge” setting. This setting is off by default: until you turn it on, Focus sends no session to iCloud.

Once on, Focus writes each completed session (identifier, kind, start, end, time zone and ritual name, a free-text field you may have typed yourself) and its daily ring to a local container shared with Forge and Habits. When iCloud is available, the same data is sent to the private CloudKit database in your own iCloud account, so Habits on another device using that account can receive it. The developer has no access to it. Habits can use it to fill habits you link to Focus. Focus adds no data read from Apple Health to this journal.

If you turn the setting off: sending stops. However, copies already sent to iCloud, or already imported into Habits or Forge, are not deleted automatically: propagation of deletions between the apps does not exist yet. To erase them today, you have to do it in the app that holds them. Local event copies are retained for 60 days; this is not a purge of CloudKit or of data already imported. Resetting Focus statistics does not delete these copies either.

This journal is separate from automatic backup: switching one off does not switch the other off.

The “Yū Studio” card in Focus simply opens yustudio.app in Safari. The app sends nothing to the website when you do so.

Location

If you enable the weather feature, the app uses your approximate location (latitude/longitude), rounded to about 1 km before it leaves the device, solely to query the Open-Meteo weather service and Apple’s geocoding service (to show your city name). These coordinates are:

• not stored,
• not linked to your identity,
• not used for tracking.

You can deny or revoke this access at any time in iOS Settings.

Health

If you turn on Health sync (off by default, in Settings), the app writes your completed breathing sessions to Apple Health as mindful minutes. Yū Focus never reads any Health data: this information stays managed by Apple’s Health system on your device, is never sent to us, and you can revoke this access at any time in iOS Settings → Health → Data Access & Devices.

Purchases

The one-time “Full Access” purchase is handled entirely by Apple (StoreKit). We neither receive nor store any payment information.

Tracking and advertising

In the app: no tracking, no ads, no third-party analytics. Yū Focus does not use App Tracking Transparency because it tracks nothing.

Websites

The yustudio.app and zenithfocus.app websites use Cloudflare Web Analytics for aggregated traffic statistics (page views, country, device type, where visits come from). This tool does not use cookies, does not build visitor profiles and does not follow people from site to site. It applies to the websites only, not to the app. Details are in the website privacy policy.
