About this app

Cards is a calm, colorful app that combines three things in one place and with one rhythm: daily tasks, goals, and learning. No corporate hype—just what you really need, on your phone and in your browser, with live syncing.

✔️ TASKS AND SHARED LISTS
• Colorful lists with cards, checklists, and notes.
• Recurring deadlines and tasks (daily, weekly, monthly, yearly)—no more missing loved ones' birthdays.
• Share lists with family or a team: invite via email, the other person accepts, and you all work on the same list.
• Change history for each card.

🎯 DAILY LOOP — GOALS AND HABITS
• Goal lists with points and daily targets.
• Track progress: % bar, streak, hourly heatmap, and summary.
• Perfect for building habits day after day.

🧠 MEMO LOOP — LEARNING WITH FLASHCARDS
• Flashcards with intelligent repetition (SM-2 algorithm, like in Anki).
• Order a ready-made set of flashcards from AI—enter a topic, and the app will organize the deck (words, definitions, quotes) and skip the ones you already have.

⚡ LIVE SYNC
• Changes on your phone appear in your browser in a split second—and on anyone you share the list with.
• Works on Android and in your browser (cards.sundata.pl).

🎨 SIMPLE AND FUN
• Minimalist, colorful interface and consistent design.
• App available in Polish, English, French, and German.

🔒 YOUR DATA
• Encrypted connection (HTTPS), passwords stored securely.
• Delete your account and all data at any time from within the app. • Privacy Policy: cards.sundata.pl/policy
