A few UI and Security related fixes and improvements

Fixes that improved native sharing, added public-deck app/universal links with hosting and native config updates plus a few small i18n and theme tweaks

- Smarter Pro usage and subscription handling - AI generation for existing decks - Mobile UI polish: deck toolbar, login above keyboard, dark mode & status bar - Better deep links, sharing, and toasts - Reliability updates under the hood

General maintenance update: including UI enhancements and minor bug fixes for improved reliability.

Subscription pricing made clearer: Savings percentage and per‑month equivalent are now calculated from the actual subscription prices instead of fixed values. When you select the yearly plan, you’ll see the correct savings % and the real monthly equivalent.

What's New in the Version 1.3 Session & offline • Session expired fix – Fixed a bug where generated cards were lost when the session expired before saving. The flow is now: • Session is checked before generation and before save. • If the session is expired or about to expire, it is refreshed when possible. • If a save fails due to session expiry or being offline, a recovery modal appears. • You can download your cards as CSV or JSON so they are not lost. • You can log in again and import the file later. File downloads • File downloads – Downloads now use the native Share sheet instead of failing silently. Users can choose “Save to Files” to store exports. • CSVImport template download – Uses the same export flow for compatibility. Import previews • Import card previews – HTML tags are stripped from previews in Document, PDF, and CSV import. Test mode • Scroll to top – Content scrolls to top when moving to the next card. • Bottom bar – Reduced height while keeping the Next button centered. • Loading state – “Loading…” text centered in the middle of the screen. • Radio-style circles – Grey circles added to options (right side); turn green/red for correct/wrong. • Layout jump fix – Reserved space for check/X icons so options don’t jump when feedback appears. • Option text margin – Removed default margin on elements in option text. • Bottom fade – Restored fade effect for truncated option text. • Hover – Disabled blue stroke hover on option buttons. • Max-width – Card width increased from 480px to 760px. • Truncation limit – Option truncation increased from 100 to 120 characters. Test results screen • Labels – “Your answer:” and “Correct answer:” are bold. • Card styling – Missed cards use white background and grey border (aligned with test mode). • Bottom spacing – Content extends to the bottom edge with correct safe-area padding. Bottom sheet • Scroll lock – Background content no longer scrolls when the Create bottom sheet is open.

TestMode: expandable options with formatting, animations, and UX improvements - Center test cards vertically on larger screens; scrollable on small viewports (iPhone SE) - Add expand/collapse for truncated options (>100 chars) with Show more/Show less link - Larger tap target (44px) and edge-to-edge separator for Show more link - Preserve HTML formatting (bold, italic, br) and decode entities (nbsp) - Smooth expand/collapse animation with bottom fade for expandable items - Add chevron icon. Allow expand/collapse after answer given - Add showMore translation (en/de) Fix: show visible checkmark in Manage deck card selection checkboxes Add custom checkbox styling to CardCheckbox since global appearance:none hides native checkboxes. Draw checkmark via ::after pseudo-element when checked, with dark mode and hover support.

Deck actions- Each deck now has three actions: Study, Test, and Insights (not only Study). Insights shows progress and wrong answers; back button returns to “My decks” when you opened it from the list, or to the deck when you opened it from the deck.Study & cards- For long content that doesn’t fit the card: an overall scroller was added and a bottom fade to the edge so you can scroll the full question or answer; layout and scroll work correctly on iPhone. Short content stays centered.- Test mode: completion screen width adjusted; header and footer stay fixed while you scroll. Navigation & lists- My decks: “Created …” dates are fully translated and show in days or months.- Referrals: "My referrals" was added so you can invite others and see their status; on small screens long emails now truncate and no longer overlap the label. General fixes- Bottom navigation and sheets respect safe area with a cleaner look.- Password reset: reset links from email open in the app and complete reliably. - Create menu: choosing any option (manual entry, AI, document, CSV, etc.) now scrolls the new screen to the top.- Create and Share bottom sheets use less space at the bottom on iPhone.
