What is my account for?

Your account initially allows you to subscribe to a plan. Then, even if your subscription expires, you'll still be able to access your palettes (without the ability to edit them) as well as your invoices until your next subscription (or for a maximum of one year).

Why buy a subscription?

Although creating your account is free, it doesn't grant you access to more editing features than the limited free version. A subscription provides you with full access to various features, including simultaneous color comparison, palette creation and management, creation of complex backgrounds, testing, simulators, and export functionalities.

How to subscribe?

Once logged in, and therefore after creating your account, you can access "My Account" (at the top left of your screen) where you can subscribe to the plan of your choice.
You will be redirected to Stripe where you can choose your payment method.
When your subscription nears its expiration date, you will have the option to renew it.

Renewals are not automatic!
