What Is Heimdall?
Heimdall is a physical, electronic key box. It locks away the real key — and only releases it once an agreed lock period has elapsed. The crucial point: Heimdall enforces the lock physically, not on the honour system.
In many chastity setups the lock period rests on trust: the wearer could take the key in theory but chooses not to. For many people that is exactly right. But for those who want a tangible barrier, Heimdall closes the gap between "I shouldn't" and "I can't".
How It Differs from the Code Vault
The tracker already has the code vault — a purely software-based solution. A photo of a key or code proof is stored sealed in the system and stays hidden until the lock period ends. So the code vault locks away a piece of information in software.
Heimdall takes the other route: it locks away a physical object in hardware. Both pursue the same goal — making a lock period more binding — but on fundamentally different levels. The code vault is usable right away and needs no extra hardware. Heimdall needs a real device, but in return offers a physical rather than a digital barrier.
Working Together with the Tracker's Lock Periods
Heimdall is not an isolated toy; it is designed to work with the tracker. The idea: the lock period configured in the tracker is the source of truth. While a lock is active in the tracker, the box stays shut. When the lock period ends — or the keyholder extends it — the box mirrors that state.
This creates an unbroken chain: the keyholder controls the lock period in the tracker, the tracker holds the state, and Heimdall enforces it in the physical world.
Honest About Maturity: MVP
Here is the unvarnished truth: Heimdall is at MVP stage. It is an experimental project for tinkerers and power users, not a finished consumer product. There is no polished enclosure you order and unbox. Anyone joining in should be comfortable with electronics, soldering and a bit of setup frustration — and with the fact that things may still change.
We say this plainly on purpose: we do not want to disappoint anyone expecting a turnkey product. Today, Heimdall is for people who enjoy building things themselves.
Build and Test With Us
Heimdall thrives on its community. If you know your way around microcontrollers, enjoy soldering or are simply curious, we welcome builders and testers. Stop by on GitHub, read the current state, open issues, share your experience.
And for context: Heimdall naturally fits best into a self-hosting setup where you already run your own tracker and enjoy tinkering with the tech. It is a power-user project — and that is exactly the appeal.
