Appstore provider

We make our App available on the Google Play Store and the Apple App Store, our app-store Providers. The ways in which you can use the App may also be controlled by your app-store Provider’s rules and policies. We encourage you to read those rules and policies and ensure that you comply with them. If there are any differences between these terms and the app-store Provider’s policies, the latter will apply.

You acknowledge that these terms are concluded between you and us, and not with the app-store Provider. We are solely responsible for the App and its content, not the app-store Provider. The app-store Provider has no liability whatsoever to you under these terms or in relation to the App.


Open source software

If any open-source software is included in the App, the terms of an open-source licence may override some of the terms of these terms. We may notify you of such terms from time to time, or you may request details of such terms, if any apply.


We may transfer these terms to someone else

We may transfer our rights and obligations under these terms to another organisation. We will always tell you in writing if this happens and we will ensure that the transfer will not affect your rights under these terms.

Rights for third parties

Otherwise, nothing in these terms is intended to confer on any person any right to enforce any term of these terms which that person would not have had but for that Act.


If a court finds part of this contract illegal, the rest will continue in force. Each of the paragraphs of these terms operates separately. If any court or relevant authority decides that any of them are unlawful, the remaining paragraphs will remain in full force and effect.


If we delay in enforcing this contract, we can still enforce it later. Even if we delay in enforcing this contract, we can still enforce it later. If we do not insist immediately that you do anything you are required to do under these terms, or if we delay in taking steps against you in respect of your breaking this contract, that will not mean that you do not have to do those things and it will not prevent us taking steps against you at a later date.


Our agreement with you

These terms constitute the whole agreement and understanding between you and us in relation to the use of our App. Except in case of fraud, all previous agreements, understandings, undertakings, representations, warranties, promises and arrangements between you and us relating to the subject matter of these terms or your use of our App are superseded, except as otherwise expressly stated in these terms.
