The SDA is more than just another handheld computer — it's a statement about digital ownership, privacy, and intentional technology use. In an era of planned obsolescence and attention-grabbing algorithms, the SDA offers a refreshing alternative: a device that truly belongs to you.

Every aspect of the SDA — from the hardware schematics to the operating system source code — is openly available for inspection, modification, and redistribution. This isn't just open-source in name; it's a fundamental design principle that ensures you remain in control of your digital life.

Platform ownership

In today's world, there are fewer and fewer devices that users can buy, understand how they work, and then adjust or customize. They can't replace or modify individual components, or add new ones. The most a user can do these days is buy a larger memory card or replace the battery. The closed nature of the system and its poor customizability and reparability may be the price to pay for the low purchase price (though this is really only a possibility). However, the closed nature of the entire software platform is inexcusable. If a user is restricted by the platform in the normal use of their device (e.g., running arbitrary code), do they actually own it at all?

SDA turns the concept of a mobile device platform on its head, giving users opportunities for self-expression limited only by the available hardware.

Hardware

Fixable, available,extensible, open.

Software Freedom

The entire OS — kernel, drivers, userspace, and applications — is open source. No proprietary blobs, no locked bootloaders, no forced updates.

Data Sovereignty

Your data stays on your device, in formats you control. No cloud sync unless you opt in, no telemetry, no advertising SDKs.

Unlike mainstream devices that lock you into ecosystems and harvest your data, the SDA gives you complete freedom to:

• Inspect and modify every line of code running on the device
• Build your own hardware from published schematics
• Create and distribute your own applications without gatekeepers
• Use the device indefinitely without forced updates or obsolescence

The result is a handheld computer that respects your time, attention, and digital sovereignty — a rare combination in today's technology landscape.
