## What is CipherDeck Secure Flashcards?

CipherDeck is the flashcard app for people who realize that what they're learning is personal.

Your flashcards reveal what you care about, what you're planning, and what you don't know yet. Other apps store them in plaintext on someone else's server. CipherDeck encrypts everything on your device before it ever leaves — we can't read your cards even if we wanted to.

ENCRYPTED BY DEFAULT
Cards are encrypted on your device using client-side encryption before they're synced. No ads, no tracking, no data sold to AI companies or ad networks. Your knowledge stays yours.

SPACED REPETITION THAT RESPECTS YOUR TIME
Powered by the FSRS algorithm, CipherDeck shows you the right cards at the right time — right before you'd forget them. Most days, you'll spend 5–10 minutes reviewing. Your brain can only absorb so much in one sitting. We respect that instead of wasting your time.

A FLASHCARD APP, NOT A SECOND JOB
No AI tutors. No gamification treadmills. No "engagement" features designed to keep you in the app longer than you need to be. You open it, review your cards, and get on with your day.

BUILT FOR REAL LIFE, NOT JUST EXAMS
• Birthdays, allergies, medications — things you should know by heart
• Interview prep for a job you haven't quit yet
• Client names, account details, sales notes from work
• A language you're learning for a trip, a relationship, a move
• Passwords and PINs you're drilling into memory

MORE FEATURES
• Track your progress as your knowledge grows over time
• Add images to card fronts and backs — encrypted like everything else
• Syncs across web and iOS
• Import and export decks

CipherDeck is free to use. Your knowledge is yours — keep it that way.
