Terms of use

Last updated: 14.08.2025

1. About the App

Wöör is a vocabulary learning app designed to help users collect words, review meanings, and practice through exercises. The App uses spaced repetition, a learning technique that shows you words at increasing intervals to help improve long-term memory retention. You can use the App without creating an account — all usage is device-based and your data is stored locally on your device.
