About PrimeTask
Built to last.
Designed to stay with you.
A productivity system that works offline, costs once, and keeps your data under your control. No subscriptions. No cloud lock-in. Just software that respects your work.
Technology should support your work, not control it.
Engineered so your data remains yours, your workflow remains intact, and your tools continue to work without dependency on external services.
Why we built this
Modern productivity software asks you to make a trade-off.
The tools are powerful - but your work lives on someone else's infrastructure. Your data sits on someone else's servers. Your access depends on someone else's pricing decisions. And if they change their terms, raise their prices, get acquired, or shut down - your workflow goes with them.
This isn't a hypothetical. It happens constantly. Prices go up. Features get paywalled. Free tiers shrink. APIs close. Companies pivot. And the people who built their systems around those tools are left scrambling.
PrimeTask was created as a deliberate response to this - not as a reaction to any single product, but as an answer to the model itself.
Your tools should outlive the companies that made them.
Our principles
What we believe
Ownership, not rental
Your tasks, your projects, your contacts, your plans - they’re your work. PrimeTask stores everything locally on your device. There is no PrimeTask account. There are no PrimeTask servers holding your data. When you close the app, your data stays exactly where it was - on your machine, in formats you can export and take anywhere.
Offline by architecture, not by fallback
Most “offline” features in modern software are afterthoughts - they work until the sync breaks. PrimeTask is offline‑first by architecture. Everything works without internet - not because we added an offline mode, but because the app was built from the ground up to never require a connection.
One payment, no recurring extraction
Subscriptions made sense when software lived on servers. PrimeTask runs on your machine. There is no server cost to pass on. You buy a licence. You own the software. Updates are included. The business model is aligned with the product: sell something good, support it well, earn trust over time.
Privacy by architecture, not by policy
Most companies say “we respect your privacy” while collecting analytics and telemetry. Their privacy is a policy - a promise that can change. PrimeTask’s privacy is architectural. Your data never leaves your device unless you explicitly choose to sync. There’s no telemetry. No tracking. No analytics. We literally cannot see your data, because it doesn’t exist anywhere we can reach.
Powerful doesn’t have to mean complicated
PrimeTask is designed for people who manage real complexity - but who don’t have a team to configure their tools. It’s a system that reveals depth gradually. Start with a simple task list and grow into projects, CRM, visual planning, and automations - at your own pace, without hitting walls.
Architecture
How it's built
Hybrid Desktop App
The core runs as a high-performance desktop app. Native Swift modules handle deep OS integration - iCloud sync, Apple Calendar, and Apple Reminders all run through native code, not browser APIs.
Offline-First Performance
Sub-second load times, smooth animations, no spinners waiting for servers. Everything works whether you’re online, offline, on a plane, or in a cabin with no signal.
Open Data Format
Your data is stored in open JSON format - readable by any text editor, exportable to CSV, and never locked behind a proprietary format. If PrimeTask disappeared tomorrow, your data would still be yours.
Available for macOS. Windows coming soon.
Our approach
Built with discipline
PrimeTask is built by a structured team with a long-term vision and a clear philosophy.
This is not a startup chasing growth metrics. It's not a side project. It's a deliberate, disciplined effort to build software that lasts - designed to stand on its own without venture capital timelines, growth-at-all-costs pressure, or the need to extract recurring revenue from users.
Every feature is considered. Every release is tested. Every design decision serves the user, not a metrics dashboard.
We're just getting started - and we're building this properly.
FAQ
Common questions
PrimeTask believes AI should assist your workflow, not do your work for you. Rather than building its own chatbot, it connects to the AI you already use, whether that's Claude, Cursor, or a local model like LM Studio, through an open standard called MCP. Your AI then works directly with your tasks, projects, and CRM through 100+ local tools. You pick the brain, PrimeTask supplies the hands. Everything runs on your machine, so your data never leaves your device. That's AI done right.
PrimeTask's privacy is architectural, not a policy. Your data stays on your device by default. It only leaves when you explicitly enable a sync method such as iCloud or your own sync folder. There's no telemetry, no tracking, no analytics. We literally cannot see your data, because it doesn't exist anywhere we can reach.

PrimeTask Mobile is in development. Instead of rushing a basic mobile app, we built deep native integrations with Apple Calendar and Reminders - so your iPhone, iPad, and Apple Watch become natural extensions of PrimeTask. Capture tasks via Siri, Reminders, or any Apple device and they sync automatically.
