DPI Slowdown

Free trial

How does the free trial work?

Open the program, accept the terms and select "Start free trial". Every feature works for 2 days from that moment, on that computer. You do not need to enter payment details.

What happens when the trial ends?

The program stops and asks for a licence key. Subscribe and paste the key from your receipt email to carry on. Your settings and profiles are kept.

I subscribed during the trial. Where do I enter my key?

The program asks for it when the trial ends. Until then you can keep using the trial; the key in your receipt email does not expire while your subscription is active.

Licence keys

I paid but did not get a key

The key is in the receipt email from Lemon Squeezy. Check your spam folder and that you used the right email address at checkout. Still missing? Email us with the address you paid with.

The program says my key was not recognised

Copy the whole key from the receipt email and paste it, without spaces before or after. Keys from other products do not work.

The program says my key is in use on the maximum number of computers

Each key works on up to computers. Email us and we will free up a computer you no longer use.

I got a new computer

Download the program on the new computer and enter the same key. If you have reached the computer limit, email us and we will remove the old one.

Does it work offline?

The program checks your subscription online when it starts. Without internet it keeps working for a few days after the last successful check, then asks you to connect.

Subscription

How do I cancel?

Use the "Manage subscription" link in your receipt email. You keep access until the end of the period you paid for.

How do I change my card or see my invoices?

The same "Manage subscription" link opens your customer page, where you can update the payment method and download invoices.

The program says my subscription has ended

Your last payment failed or the subscription was cancelled. Fix the payment method from your receipt email, or subscribe again.

How do I get a refund?

See the refund policy.
