Six Powerful Modules.
One Unified Operating System.
Every feature is architected for clarity, calm productivity, and absolute privacy on your device.
Dual Bikram Sambat & Gregorian Time Engine
Full astronomical synchronization covering 130 years. Features MoHA gazetted holidays, authentic Tithi, Paksha, Lunar phases, sunrise/sunset, multi-day festival spans, and instant dual-calendar date picking.
Lend & Borrow (लेन-देन)
Dual-entry debt and loan tracking. Link transactions to contacts, schedule repayments, track EMI installments, and evaluate arithmetic expressions like 5000*0.15+200 directly in amount fields.
CamScanner-Grade Vault
Quadrilateral edge detection, perspective skew correction, and Magic Color contrast enhancement. Search inside document images with deep OCR text indexing and export front+back cards to PDF.
Deep Task Management & Automated Recurring Bills
Smart Urgent-first prioritization, natural subtask trees, and month-clamped recurrence rules. When completing recurring bills (electricity, internet, rent), Ritikal automatically prompts to log an expense transaction in your cashflow.
Reflective Diary & Moods
Emotion-aware daily prompts, mood tags, audio note transcription, and paginated diary book viewer. Completely private with AES-256 encrypted backups.
Offline Queue & Optional Multi-Device Cloud Sync
Work completely offline with a local UUIDv7 mutation queue. When connected, sync changes seamlessly to your phone, tablet, or web app with Last-Write-Wins (LWW) resolution and zero battery drain.
Live Bikram Sambat & Gregorian Time Engine
Test the built-in astronomical converter spanning 130 years (BS 1970–2100). Zero cloud latency, calculated completely on-device.
Your Life Data Stays in Your Hands.
Zero Ads. Zero Tracking.
Most productivity apps harvest user telemetry or lock features behind servers. Ritikal is engineered with mathematical privacy.
SQLCipher At-Rest Encryption
Your SQLite database is encrypted with real 256-bit SQLCipher keys. Even if an attacker accesses raw storage, your data remains unreadable.
Zero Third-Party Telemetry
No Google Analytics, no Facebook Pixel, no ad brokers. Not a single byte of tracking code is compiled into the app.
Passphrase Encrypted Backups
Export full system backups protected by argon2id/PBKDF2 key derivation and AES-GCM ciphers with custom passphrases.
