Seyethe Flashcards 1.0.0 User’s Guide

A parent-crafted, ad-free learning tool built for mastery, concentration, and long-term academic confidence.

1. The Seyethe Standard & Philosophy

Seyethe Flashcards was built from the ground up on five uncompromising principles:

  • Zero Ads, Zero Trackers, Zero Telemetry: We collect zero data. There are no tracking scripts, analytics, or behavioral profiling.
  • 100% Offline Capability: The app never requests network access permissions. Use it on road trips, airplanes, or in quiet study environments.
  • Sound Off by Default: Audio is always muted at launch to respect parents and quiet spaces. Unmute or re-mute with a single tap.
  • Instant Pause & Exit: Real life comes first. Pause anytime or exit immediately without penalty to family dinners or bedtime routines.
  • Zero Predatory Gamification: No purchasable gems or coins. No energy meters, countdown timers, pay-to-win tricks, or micro-transactions.

2. Getting Started & Profile System

To protect privacy while allowing multiple children to learn on a single family device, Seyethe Flashcards uses symbol-based profiles (Blue Trapezoid, Green Circle, Orange Triangle). No personal identifying information (PII), names, or emails are ever entered or stored.

  • Profile Isolation: Each profile independently tracks its own Gold Mastery Stars, All-Time Best Times, Session Records, custom settings, and Smart Practice Deck.
  • Switching Profiles: Tap the active Shape Icon in the top-left corner of the main menu. Select SWITCH to choose a profile, or RESET STARS to wipe records for that specific profile (protected by the Master Lock if configured).

3. The Core Flashcard Decks

The app includes eight built-in decks sorted alphabetically on the main screen, spanning foundational math, global geography, and language skills:

Deck Name Description Key Features
Addition Auto-generated addition tables Selectable 1-, 2-, or 3-digit operands (Levels 1, 2, 3)
Division Complete 12×12 division tables Supports Standard, Vertical, & Long Division brackets
Homophones Sound-alike vocabulary Accepts multiple valid spellings (e.g., to / too / two)
Multiplication Complete 12×12 multiplication tables Horizontal and Vertical arithmetic layout choices
Spanish Core Spanish ↔ English vocabulary Full on-screen diacritics support (ñ, á, é, í, ó, ú, ¿, ¡)
Subtraction Auto-generated subtraction tables Digits 1–3; automatically clamped to non-negative results
UN World Capitals Sovereign world capitals (UN ratified) Flexible accent and alternate name matching
US State Capitals All 50 United States state capitals Multi-answer synonym and reverse prompt support

4. Game Modes & Session Configuration

Selecting any deck opens its Configuration Screen, allowing learners to tailor their practice:

  • Mode Selection: Choose QUIZ for timed testing with on-screen entry, scoring, and mastery tracking, or STUDY for self-paced, untimed card flipping.
  • Card Style (Math Decks): Choose Horizontal (9 × 5 = ?), Vertical (column arithmetic), or Long Division (formal division bracket).
  • Card Prompt (Vocabulary & Capitals): Choose Standard (Question → Answer) or Reverse (Answer → Question).
  • Session Size: Select 10 Cards, 25 Cards, or ALL Cards.
  • Difficulty: Level 1 (single-digit), Level 2 (double-digit), or Level 3 (triple-digit) for addition and subtraction.

5. Heads-Up Display (HUD) & Controls

The HUD provides real-time progress and navigation without cluttering the card face:

  • Top-Left Indicators: Shows the active Profile Badge, Card Progress Counter (e.g., CARD 3 OF 10), Animated Fill Bar, and the Live Timer (MM:SS.T). If a question is missed or skipped, a small red-slashed stopwatch icon appears, indicating the run is disqualified from a best-time speed record or Gold Star.
  • Top-Center Records: Displays both ALL-TIME (the fastest flawless run recorded on the profile) and SESSION (the fastest run in the current app session).
  • Top-Right Control Stack:
    • Home / Menu: Pauses the timer and prompts "Exit to Main Menu?" to prevent accidental loss.
    • Pause / Resume: Freezes the timer, conceals the card prompt, and reveals a large center RESUME button surrounded by a soft pulsing focus plate.
    • Audio Toggle: Mutes or unmutes synthesized audio effects.
    • End Session Early: Prompts "Are You Sure You're Done?" to conclude immediately and jump to the summary review tray.

6. Taking a Quiz & On-Screen Keypads

  • Zero-Pressure Timer: The session timer remains frozen at 00:00.0 until your very first touch input. Learners can read the prompt and think without rushing.
  • Touch-Optimized Keypads:
    • Numeric Keypad: Large touch-friendly numerals, DEL, negative sign (-), SKIP, and SUBMIT.
    • Alpha Keyboard: A 13-column layout matching QWERTY muscle memory while keeping the operating system's predictive autocorrect disabled.
    • Symbol & Accent Toggles: Tap !@# or ÁÉÑ to cycle international accents (á, é, í, ó, ú, ñ, ü, ç, ¿, ¡), and a/A to toggle case.
  • Skipping: Tapping SKIP flips the card to reveal the answer. Skipped cards are not discarded—they are re-queued at the end of the run so the learner gets another opportunity to solve them.
  • End-of-Session Review Tray: Completing a session presents a summary of correct answers, skips, and total time. If any cards were missed or took longer than threshold (>15s on math, >30s on vocabulary), up to three review tiles appear at the bottom. Tap any tile to flip between question and answer.

7. Casual Study Mode

Study Mode turns the app into a self-paced, distraction-free flashcard deck:

  • Card Flip: Tap anywhere on the card to smoothly flip between Question and Answer.
  • Navigation: Tap on-screen Left / Right arrows to browse cards, accompanied by a live progress bar.
  • Completion: Choose NEW REVIEW to reshuffle and study again, or TAKE QUIZ to test what you learned.

8. The Smart Practice Deck (Spaced Repetition)

The Practice Deck (marked with a bird in flight icon) sits in the upper-right sidebar of the main menu. Any card that is answered incorrectly, skipped, or answered slowly (>15s on math, >30s on vocabulary) is automatically routed into the student's personal Practice Deck.

  • Targeted Review: Opening the Practice Deck lets students drill their specific struggle points.
  • The 3-Streak Mastery Rule: When a student answers a practice card correctly on three separate runs, it is permanently removed from the deck.
  • Cross-Deck Intelligence: If a student encounters their practice card in another deck and answers it correctly, the streak counter still advances. The system is smart enough to add cards when needed and retire them when mastered.
  • Mastery Celebration: When all cards are cleared, the deck displays an "EMPTY! FANTASTIC!" banner with a pulsing gold star.

9. Mastery Stars & Best Times

Gold Stars reward accuracy and focus over pure speed. A session earns a permanent Gold Star when completed with 100% accuracy and zero skips:

  • 10 Star: Awarded for mastering a 10-card session.
  • 25 Star: Awarded for mastering a 25-card session.
  • ALL Mastery Star: Awarded for mastering the full deck. Rendered with a deck-themed color border and a white checkmark.
  • Star Stacking: Math decks display separate stars across Difficulties 1, 2, and 3. Vocabulary decks display a two-star stack representing Standard Mode and Reverse Mode.
  • Best Times: The app records personal bests for every combination of deck, size, and layout. Setting a new record triggers an on-screen celebration.

10. Creating & Editing Custom Decks

Create tailored flashcard decks directly inside the app in seconds:

  • Creating a Deck: Tap NEW DECK on the main menu sidebar (requires Master Lock if configured). Assign a Deck Name (up to 25 chars), choose a color from the 6-palette bar, and optionally set an up to 8-digit Deck PIN to prevent accidental edits.
  • Card Entry: Tap + ADD CARD, type the question (up to 60 chars), tap the answer box, and enter the answer (up to 30 chars).
  • Auto-Math Engine: Typing a simple integer arithmetic question (like 12 x 8 or 45 + 55) automatically computes and fills in the answer box.
  • Alternate Answers: Tap + ALT ANSWER to add acceptable synonyms or alternate spellings. The quiz engine accepts any listed variation.

11. Importing & Exporting CSV Decks

In addition to the on-device deck creation capability described above in section 10, Seyethe Flashcards additionally supports standard comma-separated value (.csv) files for creating decks on a computer or sharing them across devices:

  • Format: Use the standard structure: Question,Primary Answer[,Answer 2[,...[,Answer N]]]. Lines starting with # without commas are treated as comments.
  • RFC 4180 Compliance: Fields containing literal commas or quotes must be enclosed in double quotes (e.g., "Washington, D.C."). UTF-8 character encoding and international accents are fully supported.
  • Importing: Tap IMPORT CSV on the sidebar and select your file via the system picker. Because the app does not request network access, copy the .csv file to your device's Documents or Downloads folder first. Your source file is never modified.
  • Exporting: Open any custom deck's configuration screen and tap EXPORT at the bottom to save an RFC-compliant .csv file to your device.
What is the capital of France?,Paris,Paname
# math section
9 x 9,81
# miscellaneous
H2O,Water,Dihydrogen Monoxide
"Quotes, and commas","Supported smoothly"

12. Master Lock & Parental Controls

The Master Lock is an optional feature designed to protect administrative actions so children cannot accidentally delete decks, clear progress, or trigger system file dialogs.

  • Setting Up: Tap the Gray Shackle icon in the top-right corner of the main menu, enter an up to 8-digit PIN, and tap SUBMIT. The icon turns into an Unlocked Blue Shackle.
  • Protected Functions: Secures NEW DECK creation, IMPORT CSV file dialogs, RESET STARS profile wipes, and provides a master override if a child forgets an individual custom deck PIN.
  • Relocking & Wiping: Tap the Unlocked Blue Shackle to either RELOCK immediately (turns into a Locked Blue Shackle) or WIPE the PIN permanently. Switching profiles automatically re-locks.

13. About Screen & Transparency

Tap the Seyethe brand header on the main menu to open the system information screen. It displays the active version string, build timestamp (YYMMDDXX), full operational guarantees, and acknowledgments to open-source libraries (SDL2, NanoSVG, and Google Gemini product guidance).
