Starting with the launch of JPEGmini Pro 3 on October 2020, the licensing model changes.
The most important part of this change is that we will now require a yearly fee for updates. Once you buy JPEGmini that version is yours to keep forever, but in order to upgrade to the newest version, we ask for an additional yearly fee.
If you are an existing user of JPEGmini, you should receive a popup inside the app allowing you to upgrade with a special discount of 30%. If you don't see the banner inside the app, please email our support - firstname.lastname@example.org, with the subject: "Upgrade pricing for JPEGmini Pro 3", stating what was the email that was used to purchase JPEGmini and attach a proof of purchase (this could be a screenshot, or an email with an invoice).
