Pro

What Pro changes

• No site credit on your sheets. Free sheets carry a small all-printable.com in the bottom corner. Pro prints without it.
• Designs saved to your account. Free saves live in one browser and vanish if you clear site data. Pro keeps them against your account, so the calendar you set up on a laptop opens on a phone.

What stays free

• All 26 printables, every layout and every option
• Every paper size, at true scale
• Holidays for 42 countries, moon phases, answer keys
• Unlimited sheets, and the shareable link that restores a design

Honest limits

This is a site with no server doing the drawing — your browser makes every sheet. Both Pro features are gated in the browser: the credit is removed by client-side code, and the save button checks your entitlement before it writes. Someone determined enough can reach past either with developer tools. Pro is a fair exchange, not a lock.

What is not client-side is the entitlement itself. It lives in the database, and the security rules refuse any attempt by a browser to grant itself Pro — including the browser you are reading this in. That is checked by a test suite, against the rules actually deployed.
