## What is Calcdeck?

Calcdeck is a beautiful calculator with a persistent tape that follows you across your devices — one $7.99 purchase, no subscription wall.

Most calculators forget what you just did. Calcdeck keeps a running tape of every calculation, syncs it to your iPhone, iPad, and Mac through your own iCloud account, and wraps it all in a design you'll actually want to look at.

PAY ONCE. NO SUBSCRIPTION.
Calcdeck Pro is a $7.99 one-time purchase. Optional monthly and annual plans exist for people who'd rather not pay upfront — but the lifetime unlock is the headline, and it's always the better deal.

WHAT YOU GET FREE
• A fast, precise calculator with order-of-operations and parentheses
• A persistent tape of your last 50 calculations
• Tap any tape entry to reuse its result
• A clean default theme, light and dark

WHAT PRO UNLOCKS
• Unlimited tape — never lose a calculation again
• iCloud tape sync — the same history on every device, no account, no server
• 25 themes including Liquid Glass and retro CRT
• Units & currency conversion with bundled offline rates
• Named variables you can reuse inside any expression
• Programmer mode — hex, octal, binary, and bitwise operators

PRIVATE BY DESIGN
No accounts. No tracking. No servers. Your tape syncs through Apple's iCloud Key-Value Storage and never touches our hands. Currency rates are bundled into the app and refreshed by updates — nothing is fetched about you.

Built entirely with Apple frameworks, on-device, for people who do quick math all day and are tired of losing context.
