On-device API license management

This documentation aims at helping you understand the licensing model of MyScript on-device libraries.

Pricing model

The MyScript pricing model is device-based. A license is defined as the first launch of one application on one device.

An Internet connection is required to launch and run the library. However, a 30-day grace period is offered, from the moment the user first launches your application. A connection will then be mandatory.

As a developer, you have to embed a certificate in your application and to initialize the MyScript library with it. This certificate will identify your application and your user’s device on MyScript servers, when activating the user license.

Application developers have to pre-pay packs of licenses corresponding to the estimate numbers of users using their app. As listed in the Pricing page, a free pack of 100 licenses is offered to every developer registering on the Developer Portal. This should be enough for most developers to develop and start user tests with their app. Extra licenses packs can be bought later at any time.

License management

With your MyScript developer account, you can access your native apps dashboard. You will be able to download the certificate to embed it in your app and see your remaining pre-activated licenses. It also gives you access to the log console, that is useful to troubleshoot certificate problems while developing.

Go to the Applications tab of the On-device Dashboard to see your remaining licenses. Go to the Pricing section to buy additional licenses.


A certificate is required to use the MyScript handwriting recognition engine and gives the right to use the Interactive Ink SDK. Each certificate gives access to all widgets for a given platform.

Here is how to download the certificate for iink on-device samples:

  1. Log in at https://atk.myscript.com.
  2. Click Open on the ATK Samples application.
  3. Click on the download icon to download MyCertificate.java (Android), MyCertificate.c (iOS) or MyCertificate.cs (Windows) .

On-device Dashboard

The top menu contains 2 sections: Applications and Console, described below.


The Applications tab is useful if you develop several applications and you want to keep control of the active ones. Assuming you have developed an application named A: If you remove A from the store, you may want to prevent users from activating a MyScript license related to A.

The Applications tab displays:

  • your pack consumption,
  • a diagram of your license consumption for all your applications (or a filtered application) on a given period,
  • a list of your applications, that you can manage through the Create application, Open and Edit buttons.
Once created, the certificate identifier cannot be changed. The Edit button only allows you to add or update a description.

Click Open to open an application and thus access a page dedicated to the corresponding certificate(s).

This new page displays:

  • a diagram of your license consumption for the application (or a filtered certificate) on a given period,
  • your application name and creation date as well as a list of your certificates, that you can manage through the Create certificate, Edit, Disable and download icon buttons. This list can be filtered.

When creating a certificate you should be aware of the rules to set your identifier. They are specifics to every platforms iink SDK could handle:

  • Android, enter the application ID that is defined with the applicationId property in your build.gradle file.
  • iOS, enter the bundle identifier that can be found in your project properties (General tab).
  • Windows UWP, enter the package name that can be found in the Package.appx manifest file (Packaging tab).
  • Windows WPF, enter the assembly name that can be found in your project properties (Application tab).

Those rules are displayed in the interface if you click on the information button (surrounded i).

Note that this certificate identifier cannot be edited later

The Disable button allows you to temporarily suspend a certificate and thus the related application. Click Enable to re-activate the certificate.


The Console tab displays various 30-day-old error logs from the server.
