Duolingo builds language practice around short lessons and daily learning habits.

Product overview

Lessons combine vocabulary, listening, reading and sentence construction in short sessions. Progress, streaks and review activities help you return to material regularly instead of treating each lesson as an isolated exercise.

Super mainly improves the learning experience by reducing advertising and restrictions that interrupt practice. Review tools help revisit mistakes and weaker skills, with available activities depending on the course and app version.

Super and Max are different plans. AI conversations or video-call features should not be assumed to be part of Super. A family seat normally uses the learner’s own account, keeping course progress and learning history separate.

Getting started

  1. Choose your plan

    Review the duration, account type, availability and total before completing checkout.

  2. Open My services

    Once the order is fulfilled, check your service for the account details or activation instructions.

  3. Follow the setup instructions

    Use the official service website or app and follow the instructions provided with your service.

Where do I find my account or activation details?

Sign in to the NFXBUS account used for your purchase and open My services. Check the delivery instructions and the service dates. If the details are not available, contact after-sales support with the order information.

What should I check before using the service?

Confirm the account type, supported region and any device or usage limits shown in the plan and delivery instructions. Features depend on the service and the service you selected.

What if activation or sign-in does not work?

Open an after-sales ticket for the affected service. Include the error message, device and approximate time it happened. Never include payment card details or passwords in a public message.

Account usage guidelines

  • Use the service within the account type, region and usage limits provided with your order.
  • For supplied accounts, do not change the email, password, recovery information or payment settings unless the delivery instructions explicitly allow it.
  • Use only the access assigned to your service. Do not change another user’s profile or share the credentials publicly.
  • Keep your service information private. Contact after-sales support before changing settings to resolve a problem.
