About YumeBytes

YumeBytes is a product studio based in Tokyo. Its apps are designed so that, wherever possible, your data stays entirely on your own device — privacy comes first.

Some tools handle a minimal amount of data in order to provide their features. Even then, we collect no more than necessary, with transparency and your control as priorities.

The priority is software that is hard to break and lasts for years, rather than constantly adding new features.
