This application (app) provides offline access to more than 80 treaties and other documents relating to international humanitarian law (IHL) – most notably, the Geneva Conventions and their Additional Protocols, the ICRC’s original and updated Commentaries on the Conventions and Additional Protocols, the rules of customary IHL identified by the ICRC’s 2005 study on customary IHL and various ICRC documents on IHL. The app interface can be set to any of the eight languages listed in the settings of the side menu, under “App language”: Arabic, Chinese, English, French, German, Portuguese, Russian and Spanish.

Installation and updates

Once downloaded, the app works fully offline. When you first open “IHL”, we recommend you allow the app to complete the following processes: “Fetching IHL Treaties data”, “Fetching customary IHL data” and “Fetching PDF data”. This should take between 1 and 3 minutes. If it takes longer or if the app crashes, we recommend you complete the following steps:

1. Make sure your device is fully up to date with the latest version of your operating system.
2. Make sure your device is connected to a Wi-Fi network.
3. Open the app and wait for all data to be fetched (IHL treaties, study on customary IHL and PDFs). This should take no more than 3 minutes.
4. If steps 1–3 do not work, uninstall the app.
5. Carry out steps 1 and 2 again.
6. Download and re-install the app.
7. Carry out step 3 again.

IHL treaties

The section on IHL treaties is organized by topic, states parties and date. You can download the list of ratifications in PDF or Excel formats by tapping on “States party to the main treaties” at the bottom of the page. Each treaty has a homepage with an introduction; specific articles can be accessed from this page. The Geneva Conventions and their Additional Protocols are accompanied by the ICRC’s original and updated commentaries. Tapping on “About this text” provides general information about a treaty. If you tap on the name of a state in “State parties”, you are redirected to a list of all the treaties in force for that state.

Customary IHL

The section on customary IHL is organized by topic and then by rule (in English only). Each rule comes with an explanation. Related practice for each rule can be found online by tapping “Related practice” at the top of the page; your device must be connected to the internet to access related practice.

Law and policy documents

The section on law and policy documents brings together public documents and links from the ICRC and the International Red Cross and Crescent Movement (Movement) that present or clarify various IHL notions and related issues. It is organized by type of document. All documents are available as PDFs in various languages.


PDF versions of treaties and documents, and of volume I (rules) of the ICRC’s 2005 study, can be downloaded in any of the eight languages – provided the text in question has been translated – by tapping the bottom-right icon when in the document. All available PDFs in your device’s language are automatically downloaded when the app is first installed. We recommend installing a separate PDF reader to view files.

Search and Find in page

The app has an overall search function. There is also a “Find in page” feature for every document.


You can bookmark documents or parts of documents by tapping the icon at the bottom of the page. You can organize your bookmarks by moving them up or down in the list, which can be accessed from the homepage or the side menu. Bookmarks can also be grouped into folders that you can create and name yourself.


A share button – at the bottom of the page of every document –¬ allows you to share content through email and social media.
