Privacy Policy

Last updated: 13 November 2026

This policy explains what information Halo Design (“we”, “us”) collects through our apps, including Closed Loop, and through this website, how we use it, and the choices you have. We have tried to keep it short and plain.

The short version

  • Our apps may collect personal information and health-related information. We use it to provide the service to you.
  • We may use anonymised data to improve our apps and services. If you do not want your anonymised data used for this, you can turn it off in the app.
  • We do not sell your information, and we do not use your health information for advertising.

Information we collect

Depending on how you use our apps and what you choose to connect, we may collect:

  • Account information — such as your name and email address when you sign in with Apple or Google.
  • Health and fitness information — such as workouts, distance, pace, heart rate, heart-rate variability, resting heart rate, recovery, sleep, strain and daily steps, from sources you connect (for example Apple Health, Apple Watch, WHOOP or Garmin) or files you import.
  • Training information — your goals, race dates, target times, training preferences, how you say you feel, and the plans and sessions the app creates for you.
  • Location information — such as the routes of your runs and an approximate location used to fetch the weather forecast.
  • Calendar availability — if you connect Google Calendar, the times you are busy, used to suggest when to run.
  • Messages and feedback — what you send us by email or in the app.
  • Technical information — such as device type, app version and crash or diagnostic reports.

This website does not use advertising or tracking cookies.

How we use it

  • To provide the service: building and adjusting your training plan, analysing your runs, generating coaching advice, sending workouts to your watch, and syncing with services you connect.
  • To run, secure and fix the apps, and to respond to you.
  • To improve our apps and services using anonymised data — data that has been processed so it no longer identifies you. You can opt out of this at any time in the app's settings.

AI processing

Some features, such as coaching messages and run reviews, are generated with artificial intelligence. To produce them, relevant parts of your training and health information may be processed by AI service providers acting on our behalf. They may only use it to provide that service to us.

Who we share it with

We do not sell your personal information. We share it only:

  • With service providers that help us run the apps (for example hosting, data storage and AI processing), under obligations to protect it;
  • With third-party services you choose to connect, as needed to make that connection work;
  • If required by law, or to protect the rights, safety and security of our users or others.

Information read from Apple Health is used only to provide the service, is never used for advertising or marketing, and is never sold.

Your choices

  • Anonymised data for improvement: turn it off in the app's settings.
  • Connections: you can disconnect Apple Health, WHOOP, Garmin, Google Calendar or other services at any time in the app or in your device settings.
  • Access, correction and deletion: email us at enroll@halo-design.net to ask for a copy of your data, to correct it, or to delete your account and data.

How long we keep it

We keep your information while your account is active and for as long as needed to provide the service. When you delete your account, we delete or anonymise your personal information within a reasonable time, unless we must keep some of it by law.

Security

We use reasonable technical and organisational measures to protect your information. No system is perfectly secure, so we cannot guarantee absolute security.

Children

Our apps are not intended for children under 16, and we do not knowingly collect information from them.

Changes to this policy

We may update this policy. If we make significant changes, we will let you know in the app or by email. The date at the top shows when it was last updated.
