Support

For anything about the apps and services made by Sizu dev, please write to us using the form below.

Open the contact form

The form itself is written in Japanese, but you are welcome to write to us in English. Sizu dev is run by one person and is not a bilingual operation — we read messages and write replies with the help of translation tools. Simple, direct wording reaches us best, and we hope you will excuse any awkwardness in our reply. The two fields you need are the message body and, if you would like a reply, your contact details.
