A few clear terms.

Updated 4 October 2026

These terms cover the Deuvo marketing website and iOS waitlist. The app’s purchase terms and the relevant store’s terms apply separately to app subscriptions.

Launch availability

Deuvo is launching on Android first. The iPhone version is coming later. Joining the waitlist is free and does not create an app account, start a trial, reserve a launch date or guarantee access on a particular date.

Learning examples

The interactive examples on this website illustrate the learning experience. Their vocabulary, activity, streaks and charts are sample data, not your app progress. Learning results depend on your practice and experience.

Subscriptions

Deuvo includes limited free learning. Optional subscriptions offer unlimited access. Final prices and eligible trials appear in Google Play before purchase. Review the price, billing period and any eligible trial in the store before confirming a purchase. Manage or cancel renewals in the store where you subscribed. Deleting an app account does not cancel a store subscription.

Responsible use

Submit an email address you control. Do not use the website to submit other people’s information, send automated spam or interfere with the service. The website’s design and licensed lesson material are provided for viewing and learning previews, not redistribution.

Updates and support

Features, launch timing and availability may change. These terms may be updated to reflect the service. For questions, use Contact. Nothing here limits rights that apply to you under relevant consumer law.
