Openza Tasks

Windows Native. Local First. Open Source.

Openza Tasks is a Windows-native task manager for people who want fast local task capture with optional provider sync. The active app is built with WinUI 3 and stores data locally in SQLite.

Openza Tasks is maintained by Deependra Solanky as a personal open-source project. Microsoft sign-in may show the Openza app name with the solanky.dev publisher/contact identity.

Download

Openza Tasks V1 is live on the Microsoft Store:

• Install from Microsoft Store

Legacy Flutter-era packages remain available in older GitHub releases, but they are no longer the active product line. Store V1 starts with a clean WinUI workspace and can reconnect integrations.

Building From Source

Prerequisites

• Windows 10 22H2 or Windows 11
• .NET 10 SDK
• Visual Studio 2026 Community or newer with:
  • .NET desktop development
  • Universal Windows Platform development
  • Windows App SDK C# components

Microsoft's WinUI setup can install the required workloads:

winget configure -f https://aka.ms/winui-config

Build And Test

dotnet restore Openza.Tasks.slnx
dotnet test src\Openza.Tasks.Tests\Openza.Tasks.Tests.csproj -c Release
dotnet build src\Openza.Tasks\Openza.Tasks.csproj -c Release -p:Platform=x64 --no-restore

Run In Visual Studio

1. Open Openza.Tasks.slnx.

Architecture

src/
  Openza.Tasks/        WinUI 3 packaged app
  Openza.Tasks.Core/   SQLite data, backups, import/export, provider sync
  Openza.Tasks.Tests/  Unit, repository, backup, and sync tests

The sync engine is C# in Openza.Tasks.Core. Historical Rust FFI work is preserved in git history and legacy releases; it is not shipped with the WinUI app.

Legacy Flutter App

The last Flutter-era mainline is preserved on the legacy-flutter-app branch. New development, issues, and releases target the Windows-native WinUI codebase in src/Openza.Tasks/.

See docs/architecture.md for the V3 task model, provider wrapper pattern, and future sync-route design. See docs/design-guidelines.md for the Openza Calm Fluent production UI language.

Microsoft To Do and OneDrive backup use Openza's built-in public Microsoft app registration. Developers can override the public client ID at build time for testing, but normal users do not need to configure Azure app registrations or client IDs.

Privacy

Openza Tasks does not add telemetry or analytics. Todoist tokens and OneDrive backup passphrases are stored locally using Windows Credential Locker. Microsoft sign-in uses the local MSAL cache encrypted for the current Windows user. See PRIVACY.md.
