Terms of use

Using Lexifour

Lexifour is an independently operated bootstrap project. It is not represented as a corporation or registered proprietorship. By using the service, you agree to use it lawfully and not interfere with the game, accounts, billing, moderation, publication, or security systems.

Timed Play permits one resumable attempt per day. A Free account includes 20 Learn answers per Vancouver calendar day; Pro includes ad-free access and unlimited Learn. Do not automate abusive traffic, evade access controls, probe other users' data, manipulate leaderboards, or publish harmful, deceptive, infringing, or abusive names or group content.

Accounts and public features

You are responsible for access to your Google account and for information you choose to publish. Leaderboard participation can be turned off. Lexifour may block, review, hide, or remove public names or groups that violate the moderation policy. Report concerns to support@lexifour.com.

Choose a name or nickname. No political slogans, campaigning, harassment, hate speech or profanity. This rule applies regardless of viewpoint. Nationality, religion and sexual orientation are not prohibited identities. A hidden display name does not remove your account or scores; you can choose another name. Contact support if you believe your name was hidden by mistake.

Subscriptions

Pro costs US$4.99 per month with no trial and is the only paid plan currently offered. Subscriptions renew until cancelled. Existing Premium subscribers retain their legacy plan and may manage it through the Customer Portal, but Premium is not available for new purchases. The complete pricing, refund, cancellation, failed-payment, and tax terms are in the Billing policy and form part of these terms.

Content and availability

Lexifour provides vocabulary games and learning material for general educational use. We work to review questions and definitions, but do not promise that every item will be error-free or suitable for a particular purpose. You may report ambiguous content from Learn or through support.

The service may change, pause, or fail. We may suspend access needed to protect users, providers, data, or the service. To the extent permitted by applicable law, Lexifour is provided without warranties and liability is limited; rights that cannot legally be excluded remain unaffected.

Privacy and changes

The Privacy policy explains data handling, cookies, providers, retention, export, and deletion. Material policy changes will be published with a new effective date. Continued use after a change means the updated terms apply, subject to applicable law.
