Stride privacy policy

Last updated 20 October 2026

Stride is a running training app made by Bunkworks Ltd, a company registered in the UK ("we", "us"). This policy explains what happens to your information when you use Stride. In short: your training plan and your Apple Health data stay on your iPhone, and the only data that leaves your device is what Google's advertising service needs to show ads.

Information that stays on your iPhone

  • Your plan and settings: your race, race date, a recent 5K time, your running days, how sessions felt and your preferences. These are stored only on your iPhone, inside the app.

  • Apple Health data: if you allow it, Stride reads your running workouts (date, distance, duration and average heart rate) to tick off completed sessions, show your progress and adjust your paces. Stride only reads from Apple Health and never writes to it. Health data is processed only on your device. It is never sent to us, never shared with anyone else, never stored in iCloud and never used for advertising or marketing.

  • Apple Watch workouts: if you allow it, Stride sends your upcoming sessions to the Workout app on your Apple Watch through Apple's WorkoutKit. This happens between your own devices.

We don't run any servers for Stride, there are no user accounts, and we can't see your plan or your health data.

Advertising

Stride is free and shows small banner ads provided by Google AdMob (Google Ireland Limited in the UK and EEA). To show and measure ads, Google's software in the app may collect:

  • your device's IP address, used to estimate your general location (country or city, never your precise location)

  • device identifiers that are limited to the app or its developer (Stride never asks for permission to track you, so iOS blocks access to your device's advertising identifier)

  • information about the ads you see and tap, how you interact with the app, and crash and performance data

In the UK, EEA and Switzerland, Stride shows Google's consent message before any ads load, so you can choose whether Google may use your data for personalised ads. You can change your choice at any time in Stride under Settings › About › Ad privacy choices. Stride never passes your plan, your health data or anything about your training to Google or to advertisers.

Google's use of data is described in How Google uses information from sites or apps that use its services and the Google Privacy Policy.

Legal basis (UK GDPR and EU GDPR)

For Apple Health data, the legal basis is your explicit consent, which you give through Apple's Health permission screen and can withdraw at any time in the Health app. For advertising, the legal basis is your consent where the law requires it, given through the consent message, and otherwise our legitimate interest in funding a free app.

Your rights

You can delete everything Stride stores by choosing Settings › Start a new plan or by deleting the app. You can stop Stride reading Health data in the Health app under your profile › Apps › Stride. For data held by Google, see Google's privacy policy above. Under UK and EU data protection law you have rights to access, correct, delete and object to the use of your personal data, and you can complain to the UK Information Commissioner's Office (ico.org.uk) or your local data protection authority.

Children

Stride isn't aimed at children under 13, and we don't knowingly collect information from them.

Health disclaimer

Stride gives general training guidance, not medical advice. Check with a doctor before starting a new training plan, especially if you have a health condition, and stop if you feel pain or unwell.
