Duple Documentation and Tutorials

We offer a 15 days free trial so you can test Duple and see if it is a good fit for you, before deciding on whether to subscribe. You don't have to register or do anything: just download the app and launch it.

Once the free trial ends, you will be notified that you need a serial number to continue using Duple. No, we don't miss the 90s! We offer privacy, so we don't like to store our user's login and password. For this reason, we use serial numbers. It's more private.

You can get a serial number here. Once subscribed, you will receive your serial number by email. This serial number is personal and lets you unlock up to 5 devices. Keep it safe, as you will need it to modify or cancel your subscription.

Your serial number will stay the same, you don’t need to re-enter it when your subscription is renewed. Everything is done automatically.

Once you get your serial number by email, use the Serial Number menu (right click on the Duple logo near the clock):

Nothing complicated, enter your serial number, validate and that's all!

You can also manage, update or cancel your subscription here.
