Privacy Policy

Health Data

With your explicit permission, we access health and fitness data from Apple HealthKit, including:

• Step count
• Distance walked/run
• Active energy burned

This data is used solely to display your fitness progress within the App. We do not sell or share your health data with third parties for advertising purposes.

Account Information

If you create an account, we collect:

• Email address
• Display name (optional)
• Username — a unique public handle, assigned when your account is created and editable in the App. This is how other people find and add you
• Profile picture (optional)
• Your clock's offset from UTC — a number such as +1 or −8, reported by your device. Bubble uses it so each person's daily total is measured against their own day: someone eight hours ahead has been awake longer, and without this their total would not be comparable to yours. This is a clock offset shared by whole continents, not a location — it cannot distinguish Berlin from Lagos — and the App does not request location access at all
• The country your device is set to, as a two-letter code. This is the region you chose when setting up the phone, read without any location permission; it is not where you are and does not change when you travel. It is displayed in Bubble next to the clock difference, and only to members whose clocks differ from yours — people in your own time zone are not shown it

Bubble (sharing with other people)

Bubble lets you follow a small number of people and compare step counts. It works only on mutual consent, and it is the one place the App shows your health data to another person:

• You add someone by their username; they must add you back before either of you can see the other's step counts. A one-way add reveals only that an account exists, with its username, display name and avatar — never any health data
• Once mutual, each of you can see the other's step totals for today, the current week and the current month. No other health data is shared
• Removing someone ends the link in both directions immediately
• We store who you have added, so the link survives between sessions. Deleting your account deletes these records in both directions
• Bubble is independent of the public leaderboard setting: turning the leaderboard off does not hide you from people already in your bubble, because they are there by your own mutual consent
• You are only discoverable by an exact username search. The App has no browsable directory of users

Usage Data

We may collect anonymous usage statistics to improve the App:

• App crashes and errors
• Feature usage patterns
• Device type and operating system version
