Each app is free to use, and a purchase is yours for good.

The main job of each app is free.

Each K app is free to download, and it does its main job for free, with no ads and no time limit. In K Photos that means browsing, viewing, sorting, sharing, copying and moving your photos, and the basic edits. Each app's page lists what is free in that app.

Everything else is free to try for 30 days.

The trial covers everything in the app. The trial is free, and you enter no payment details to start it. It starts when you first finish something with a paid tool, such as a save or an export, so looking around does not use it up.

After the trial, the paid tools still work 5 times a month.

When the trial ends, the free main job goes on as before. Most paid tools then give you 5 finished results a month for free. Trying a tool and looking at its preview does not count. Only a finished result does.

You buy an app once and keep it.

A purchase removes every limit in that app, and the app is yours for good. It also brings the new features of the next 12 months. One purchase of every K app together is offered as well.

If you own single apps and later buy all of them together, you pay only the difference.

A yearly renewal is optional.

After the first 12 months you can renew for another year of new features, or you can stop. Stopping takes nothing away. Everything you had keeps working, and bug fixes and security fixes stay free for everyone.

The store handles the money.

You buy inside the app, through the store you installed it from. The store takes the payment, and refunds follow the store's own rules. We never see your card.

On Google Play, a purchase covers the Android phones and tablets on your Google account.

The apps do not push you to buy.

There are no ads and no pop-ups asking you to pay. The trial sends one reminder, five days before it ends.
