THE MANIFESTO

The ToDoz Philosophy

Modern productivity software has lost its way into subscription paywalls, tracking telemetry, and sluggish cloud bloat. ToDoz returns to sovereign first principles.

PRINCIPLE 01

Sovereignty

Users control their data, infrastructure, and ability to migrate. Local ownership and self-hosted sync with freedom from mandatory cloud accounts.

PRINCIPLE 02

Locality

Core functionality runs on the user's device. Offline operation is not an emergency fallback; it is the normal operating model.

PRINCIPLE 03

Predictability

Critical operations are deterministic, transparent, and testable. Intelligence may assist, but mathematical rules must govern.

PRINCIPLE 04

Responsiveness

Respect human attention. Immediate sub-100ms feedback on local interactions without sluggish loading spinners or distracting clutter.

PRINCIPLE 05

Focused Interoperability

Separate operational tasks from reflective notes. Connect tools through open URIs, Markdown links, and standard calendar feeds.

PRINCIPLE 06

Longevity

Information should outlive individual software applications. Open formats (SQLite, Markdown, JSON, ICS) survive for decades.

ENGINEERING CRITERIA

The 7 Core Tests

Airplane Test • 100ms Test • Longevity Test • Responsibility Test • Dependency Test • Predictability Test • Security & Recovery Test.

ENGINEERING FOUNDATIONS

Built with Craftsmanship

Modeled on Todoist’s peak workflow speed and enhanced with native offline database storage and self-hosted control.

100% Offline SQLite Store

Runs on Drift SQLite. Complete tasks, reorder boards, and filter views instantaneously on planes, trains, or offline server rooms.

Mathematical Recurrence

Supports every! 2 months (completion-based), every 1st wed, every last workday, and explicit refusal of ambiguous grammar.

Google Calendar Time-Grid

Native 15-minute slot time-grid in Day, 3-Day, Week, and Month layouts. Drag to reschedule or adjust durations with live Google Calendar sync.

Boolean Filter Engine

Full query grammar: (today | overdue) & #Research, p1 & overdue, p4 & today, and due before: next monday.

Zero-Password Pairing

Join devices via short-lived cryptographic pairing codes. No plaintext passwords or email verification traps required.

Self-Hosted Sync Server

Lightweight Docker service using field-level Last-Write-Wins (LWW) conflict resolution and Tailscale mesh support.

VIEW DIMENSIONS

One Task Model. Three Perspectives.

Switch between chronological time blocks, visual kanban pipelines, and hierarchical project trees.

Drawn natively with a "now" marker line, side-by-side overlapping event handling, and 15-minute snap handles:

• Day View      - Micro-schedule today's hours with exact 15m time blocks
• 3-Day View    - Multi-day tactical sprint planning
• Week View     - Broad 7-day operational horizon
• Month View    - High-level bird's-eye view with drag-and-drop reschedule
          

Mathematical natural language recurrence parsed offline with deterministic precision:

every day                        -> Repeats every calendar day
every mon, fri at 8pm            -> Strict day-of-week & time constraints
every 1st wed                    -> Dynamic positional week calculations
every! 2 months                  -> Completion-based (schedules from when you finish)
after 10 days                    -> Exact delay interval after checkoff
          

Boolean query language evaluated across priorities, dates, labels, and project hierarchies:

(today | overdue) & #Research       -> High-priority focus for active research papers
p1 & overdue, p4 & today            -> Critical items + low-stress items
##Engineering & %bologna             -> Sub-projects matching specific tags
due before: next monday & !assigned -> Tasks requiring personal triage this week
          

Field-level Last-Write-Wins (LWW) ensures offline multi-device edits merge cleanly:

• SQLite Triggers record modified fields to a local dirty log
• Incremental sync transfers only delta changes upon network reconnection
• Android WorkManager keeps background reminders refreshed every ~15 mins
• Windows Toast notifications fire even when the application is completely closed
