JustInterval.app (“we”) operates justinterval.app.

Workout data

The timer and workout builder run in your browser. If you choose “Save Publicly,” the workout name, interval descriptions, durations, cadence targets, rounds, warm-up, and cool-down settings are stored in our public Firebase Firestore community database. No account is required, so do not include personal or sensitive information.

Anyone using the app may view and load public community workouts. Share links contain the workout structure directly in the URL and are not uploaded merely by creating or opening a link.

Analytics and browser storage

JustInterval does not load third-party analytics or tracking scripts. The app does not set browser cookies or use local storage. Firebase Hosting and Firestore may process standard technical request information needed to deliver the site and community-workout service.
