We Are Going Open Source

We're making our server code open source to accelerate innovation. We believe that open source is the future of software development, and we're committed to making our code as accessible and easy to use as possible. We are currently working on cleaning up the code so we can make the project public on Github.

Manage Subscriptions with LinkFive

Purchase Overview for all users on all platforms

You can see all purchases for each of your users at a glance.

If you want to give a user premium for a month through a customer request, you can simply create a custom plan for that user.


We connect all user sessions to your internal user ID

Whether your user is on Android, iOS or Web, we link all sessions to your own User ID and give you full control.

And if one of these sessions makes a purchase, all user sessions will receive the same premium status.

Server Api

When a user purchases a product in your app, we store the purchase in our database and update the entry if the user cancels it. You can then retrieve the purchase with your server and our Api-Key, regardless of which app store the purchase was made in.

Our Server Api has several API-Endpoints. Please check out our Swagger Documentation
