Terms of Use

Effective June 12, 2026

The app

Leksika is a Russian vocabulary app made by Colmena Labs. It is provided as is, without warranty of any kind. We work hard to keep the dictionary accurate, but language data is large and imperfect; definitions, stress marks, and examples may contain errors.

License

Use of the app is licensed, not sold, under Apple's Licensed Application End User License Agreement.

Leksika Pro

• Leksika Pro is available as a monthly or yearly auto-renewing subscription, or as a one-time lifetime purchase.
• Subscriptions may include a free trial. Payment is charged to your Apple Account at confirmation of purchase, or at the end of the trial.
• Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel them anytime in your App Store account settings.
• The free parts of Leksika (the widget, Learn, search, and saving words) remain free.

Dictionary content

The dictionary is a modified derivative of OpenRussian, English and Russian Wiktionary (via Wiktextract), and Tatoeba, and is shared under CC BY-SA 4.0 (sentences under CC BY 2.0 FR). You may export and reuse the database under those licenses; the app's Acknowledgements screen provides the export.
