App terms of use

Last updated 30 October 2026

These terms apply when you download or use any app or game published by Rubdexide Technologies Private Limited ("Rubdexide", "we", "us"), including Lettrova, Duelova, Tezzaro (each an "app"). By using an app you agree to these terms. If you don't agree, please don't use the app.

Licence

We give you a personal, non-exclusive, non-transferable, revocable licence to use the app on devices you own or control, for your own non-commercial entertainment. The app is licensed, not sold. You may not copy, modify, sell, rent, reverse-engineer or redistribute the app or its content, except where the law allows it.

Store terms

You also have to follow the terms of the store you downloaded the app from. For apps from Google Play, the Google Play Terms of Service apply. If we publish an app on the Apple App Store, Apple's Standard Licensed Application End User License Agreement applies to it as well, and Apple is not responsible for the app or its support.

Coins, lives, boosters and scores

Coins, lives, boosters, stars, scores and other in-game items have no real-world value. They cannot be exchanged for money or prizes, sold or transferred, and they may be changed or reset when the app is updated. There are no paid purchases in the current versions of our apps. If we add any, the price will be shown in the store before you pay, and refunds follow the store's refund policy.

Ads

Our apps are free and show ads from Google AdMob. Rewarded videos are optional: you watch one only when you choose to, for an in-game reward. We do not control the content of every ad. If you see an ad that seems wrong, email us the app's name and what you saw.

Fair play

Don't use cheats, bots, modified versions of the app or tools that interfere with ads. We may stop supporting devices or versions that break these rules.

Your progress

Your progress is saved only on your phone. We can't restore it if you uninstall the app, clear its data, or reset or change your phone.

Our content

The apps' names, logos, artwork, levels, clues, code, music and sounds belong to Rubdexide Technologies Private Limited or its licensors. Word lists and open-source software used in the apps stay under their own licences, listed inside each app.

Changes and availability

We may update, change or stop offering an app or a feature at any time. We may also update these terms. The date at the top shows the latest version, and using an app after a change means you accept it.

No warranty

The apps are provided "as is" and "as available". To the extent the law allows, we make no promise that an app will always work, be error-free or be available on your device.

Limitation of liability

To the extent the law allows, Rubdexide is not liable for indirect or consequential losses, or for lost game progress, arising from the use of an app. Nothing in these terms limits rights you have under consumer law that cannot be excluded.

Children

Our apps are made for a general audience aged 13 and over. If you are under the age of majority where you live, use the apps with a parent's or guardian's permission.

Governing law

These terms are governed by the laws of India. Courts in Himachal Pradesh, India have jurisdiction, unless the consumer law of your country gives you the right to bring a claim where you live.
