D1N LLC (“we”, “our”, “us”) operates the Zen Walk mobile application (“the App”).
This Privacy Policy explains how we collect, use, store, and protect your information when you use Zen Walk.

By using the App, you agree to the practices described in this Privacy Policy.

We aim to collect and store as little personal data as possible.
Zen Walk does not require account creation or personal profile information.

We may collect the following:

• Device type

• Operating system

• App version

• Basic diagnostic data
  This helps us improve app performance and fix bugs.

If you choose to connect Zen Walk to Apple Health or other supported health platforms, we may access:

• Step count

• Walking distance

• Calories burned

• Height and weight (if authorized)
  We only access the data you explicitly permit.
  This data stays on your device unless you choose to export it.

If you manually enter your height or weight, this data is stored only on your device to calculate walking insights, calorie burn, and related metrics.

If location tracking is enabled for walking sessions, we may collect:

• GPS walking route

• Distance traveled

• Real-time pace
  Location data is used only for walking features and is never shared.

We use collected data exclusively to:

• Provide walking statistics and insights

• Calculate distance, calories, and pace

• Improve app functionality

• Maintain app stability and performance

• Personalize your walking experience

We do not:

• Sell your data

• Share your data with third parties for advertising

• Use your personal data for tracking across apps or websites

• All health, body metrics, and location data are stored locally on your device unless otherwise specified.

• We implement standard security measures to protect data.

• No personal data is stored on Kello Solutions servers unless requested by the user (e.g., via support email).

Zen Walk may use third-party frameworks for analytics or crash reporting (e.g., Apple or Google services). These services may collect non-personal data such as:

• Device type

• Crash logs

• Performance metrics

We do not provide these services with health data, location data, or manually entered metrics.

If you choose to connect Apple Health:

• Zen Walk reads only the data types you authorize

• Data is used solely for display and calculation inside the App

• We do not store HealthKit data externally

• We do not use HealthKit data for advertising or tracking

Zen Walk is not intended for children under 13.
We do not knowingly collect personal information from children.

• Data stored on your device remains until you delete the app or manually remove it.

• No personal data is stored on our servers unless you voluntarily contact support.

Depending on your region, you may have rights to:

• Access your data

• Delete your data

• Modify your data

• Withdraw permissions (e.g., Apple Health, location)

All permissions can be managed through your device’s Settings.

We may update this Privacy Policy from time to time.
The latest version will always be available within the app or on request.
Continued use of the app means you accept any updated terms.
