two principles. one refusal.
most software is built to capture your attention and keep it. sanctuary is built on the opposite premise — and shaped by sovereignty tech and slow tech.
what is sovereignty tech?
Sovereignty tech is software designed so the person using it keeps ownership of their data, their attention, and their emotional state. It is built without engagement optimization, behavioral tracking, or dark patterns, so the tool serves the user rather than extracting from them.
The refusal is architectural, not a promise. The point is to build a system that cannot betray you, because the capacity to do so was never engineered in. Its principles, in five tabs:
only what's required to keep the path open is collected. nothing is kept "just in case."
Sanctuary's data sovereignty specification describes exactly how each of these is enforced in the product.
what is slow tech?
Slow tech is an interface design philosophy that paces interaction to the human nervous system. It is sensory-grounded, low-stimulation, and free of urgency mechanics, so that using the software helps a person regulate rather than escalate.
Fast software raises arousal on purpose — each streak, badge, and endless feed is a small spike, and the spikes are the product. Slow tech inverts the goal: the interface breathes, and the only measure of success is whether you leave more settled than you arrived. Its principles:
motion moves at the speed of a slow breath, not a notification.
what is sensory-grounded interface design?
Sensory-grounded interface design uses pace, breath, sound, and visual stillness to keep a person grounded in their body, rather than pulling their attention toward notifications, streaks, or feeds.
It is the practical craft underneath slow tech: attention turned inward and downward, into breath and the present moment. Not decoration — the regulation itself. Here is one. Tap it, and follow.
how to regulate your nervous system with software
You cannot outsource regulation to an app. What software can do is shape the conditions: remove the urgency mechanics that raise arousal, pace interaction to the breath, ground each session in one small sensory action, and never reward you for staying longer than you need. Sanctuary's four-stage method puts this into a daily practice, and the science of heartbreak explains why the body, not just the mind, is what is being tended.
a person in grief is already dysregulated. software built to capture attention makes it worse, one spike at a time. these two principles are the answer — your data and your attention, returned, at a pace that helps you come back to baseline.
