THE MANIFESTO

The ToDoz Philosophy

Modern productivity software has lost its way into subscription paywalls, tracking telemetry, and sluggish cloud bloat. ToDoz is a reference implementation of Sovereign Personal Software, built around four foundational principles with AI used to lower the cost of building it, not to add weight to the product.

PRINCIPLE I

Sovereignty

Authority belongs to the user. Tasks live in a local SQLite database you control, with self-hosted sync, revocable device tokens, and freedom from mandatory cloud accounts.

PRINCIPLE II

Longevity

Information outlives software. Documented SQLite schemas, portable exports (JSON, CSV, ICS), and verified backups keep your commitments readable for decades.

PRINCIPLE III

Locality

Independence is designed in. Creating, completing, searching, and filtering tasks work completely offline; synchronization is an optional transport, never a prerequisite.

PRINCIPLE IV

Transparency & Control

Consequential behavior remains governable. Recurrence rules and Boolean filters are deterministic and testable, every change is logged with Undo, and sync rules are disclosed honestly.

SUPPORTING QUALITY · T6

Interoperability & Maintainability

Focused task execution that connects to Markdown vaults, journals, and calendars via documented REST APIs, signed webhooks, ICS feeds, and CSV/JSON interchange.

SUPPORTING QUALITY · T7

Human Experience & Speed

Immediate sub-100ms feedback on local SQLite operations, keyboard-first Quick Add, and respectful notifications without dark patterns or cloud spinners.

EVIDENCE-LED EVALUATION

Five Eligibility Requirements (E1–E5) & Seven Verification Procedures (T1–T7)

Ownership & Exit (T1) • Preservation & Recovery (T2) • Offline Independence (T3) • Operational Transparency (T4) • Security, Custody & Continuity (T5) • Interoperability (T6) • Human Experience (T7).

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 Style Time-Grid

Day, 3-Day, Week, and Month in light and dark, on the web, Windows and Android. Tap a slot to add, drag to move, drag the bottom edge to resize in 15-minute steps, and see repeating tasks on their later days.

Location Reminders

Save places like Work or Home and get “when I arrive” or “when I leave” reminders on Android, even while the app is closed. Pick the place on an OpenStreetMap map or use your current location.

Reminders on Every Device

Several time reminders per task on Android and Windows, with Complete and Snooze buttons on the notification and an optional daily digest. Windows reminders fire even when ToDoz is closed.

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 (computers and tablets)
• Month View    - High-level bird's-eye view with drag-and-drop reschedule
• Tap a slot to add, drag to move, drag the bottom edge to resize
• Repeating tasks show faded on their later days
• Light and dark, the same on web, Windows and Android
          

Reminders that follow you, not the clock (Android). Android's own geofencing watches the places while ToDoz is closed:

• Save a place: tap the map, use your current location, or type coordinates
• On a task, choose Location: "When I arrive" or "When I leave"
• Arrive at Work  -> "Talk to Sam - You arrived at Work"
• Needs location set to "Allow all the time"; takes a minute or two to notice
• Places sync between your devices and stay private to you
          

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
