What owning software means.

Most apps are rented now. Telu is one of the few you actually own.

🔒
No cancellation needed
Nothing to cancel. No free trial that auto-converts. No "you'll be charged unless you cancel" - because there is nothing to cancel.
⚡
Works if we vanish
Telu has no dependency on our servers or this website. If we shut down tomorrow, your copy still opens, still works, indefinitely.
💳
Price never changes
You pay once. That transaction is complete. The price cannot go up because the purchase is already done.
📄
A file, not a service
You get Telu.html. Copy it, back it up, email it to yourself. It is your file in exactly the same way a Word document is your file.
🌟
Everything included
No feature tiers. No "upgrade to Pro" for the calendar or backup features. One purchase, full product.
🔄
Free updates to this version
If we release improvements to the current version, they come to you at no extra cost. You bought the product, not a snapshot.

Why one-time purchase software has become rare

Most software has moved to subscriptions because recurring revenue is more valuable to a business than a one-time sale. From a company's perspective it makes complete sense. From a user's perspective, you are renting software indefinitely and the cost compounds year after year.

One-time purchase software is still possible when the product has no ongoing server costs. Telu has none. It is a single HTML file that runs locally in your browser. There is no cloud to maintain, no sync infrastructure to pay for, no reason to charge monthly.

What "works forever" actually means

Telu.html is a standard HTML file using browser APIs that have existed for over a decade. There is nothing in it that requires ongoing support from us. Open it in any modern browser in 2030 and it will work exactly as it does today.

How it works technically

Telu is a self-contained HTML file. All the code, styling, and logic lives in a single file. When you open it in your browser, it runs entirely locally. Your tasks are stored in your browser's localStorage - a built-in database on your device. Telu makes zero network requests. It has nowhere to send data and nothing to phone home to.

This architecture is why a one-time purchase is possible. There is nothing to run on our end once you have the file.

Is there a catch?

The honest trade-off is cross-device sync. Subscription task managers sync automatically between your phone, laptop, and desktop. Telu does not - moving your tasks to another device means exporting a backup file and importing it. One deliberate step rather than automatic magic.

If you mainly work on one device, or you are comfortable managing a file, there is no meaningful catch. If seamless multi-device sync is critical to how you work, Telu may not be the right fit.
