Price in US dollars. The App Store shows the price for your country. Keepsign PDF for Teams will be available after the main app.
A PDF app is a tool. You shouldn’t rent it.
Keepsign runs on your device. There are no servers to pay for every month, so there’s no reason to charge you every month.
Pro includes future versions of Keepsign. It is shared with up to five family members through Family Sharing, and it works on every iPhone, iPad and Mac signed in to your Apple Account.
Before buying, try any three Pro jobs for free. A job counts when it’s done, such as the Word file made or the copy compressed, not when you open the tool. Whatever you made with a free try is yours to keep.
Three years of PDF tools, side by side.

Questions about buying
Do I pay again for the Mac?
No. Keepsign is one app for iPhone, iPad and Mac. Buy Pro once and it unlocks on all your devices with the same Apple Account.
Can my family use my Pro?
Yes. Keepsign Pro supports Family Sharing, for up to five other people in your family group.
How do I restore my purchase on a new device?
Open Settings › Keepsign Pro and tap Restore Purchases. It usually unlocks on its own when you sign in with the same Apple Account.
Can I get a refund?
Purchases are handled by Apple, so refunds are too. Request one at reportaproblem.apple.com. When Apple refunds Pro, the Pro tools lock again; what you saved stays yours.
Will features I use for free become paid later?
Reading, filling, signing, saving without breaking, the receipt and passwords will stay free. If you already keep several saved signatures, you keep them.
Why a separate app for Teams?
Apple’s volume purchasing for companies and schools can’t buy in-app purchases. A separate paid app with Pro built in is the way Apple suggests for organizations.
