Last updated: June 7, 2026

At Jamlex ("we"), your privacy matters to us. This policy explains what information we collect when you use the Jamlex app, how we use and store it, and what rights you have over your data. By using Jamlex, you agree to the practices described in this policy.

To make your learning experience personal and to track your progress, we store data related to your learning, including:

  • The words you've learned
