TauCore™ is a complete, secure, zero-telemetry operating system for desktop and mobile—with first-party apps, encrypted services, and enterprise controls.
No ads. No trackers. No data resale. Ever.
We built TauCore™ with one idea in mind: technology should belong to people, not the other way around.
Your data, your conversations, your photos, your work — they're yours. TauCore™, TauMail, and TauCloud are here to give you the tools to use technology freely and safely, without losing control of what matters most: your privacy.
We don't track, we don't sell data, and we don't make you the product. We simply provide the platform — you stay in control.
From kids discovering the internet for the first time, to grandparents staying connected, to professionals managing sensitive work — TauCore™ is built so that anyone, at any age, can use it with confidence.
TauCore™ is developed and maintained under The Tau Foundation, a nonprofit organization inspired by the model of the Linux Foundation.
TauCore™ and related services comply with international privacy and consumer protection standards, including:
No matter where you are, your rights are respected.
