The privacy friendly smart home

Do we have to choose between privacy and convenience?

Candle is a privacy focused smart home demonstrator. Our prototypes prove it's technically possible to build a privacy respecting smart home while maintaining convenience.

Candle is being developed by a collective of designers, artists and privacy experts from Amsterdam. While the main goal is raising awareness, we're also interested in working with partners to bring these innovations to market.

T‌he project is funded by the Dutch Fund for the Creative Industries, and has received EU funding through the Sherpa research program for ethical AI.

Privacy by Design

Candle is "cloudless": your data never leaves your home.


Family and friends shouldn't feel watched or profiled in your home. That's why some of the devices can generate fake data.

Open Source

To make devices more transparent and trustworthy, all the source code is freely available.

E‌asy to use 

Candle supports local voice control.

M‌ore secure 

Because Candle devices do not use WiFi to communicate and do not connect to the internet by default, they are more difficult to hack.

DIY friendly

You can re-create Candle by buying and assembling the parts yourself. Our guides make it easy to do - no soldering or programming is required.
