Contact us
One email address for everything. A person reads every message.
Sign up
Anyone can create a free account: your email, a password, and a code we email you to confirm it. If the code does not arrive, check your spam folder, then write to us.
A figure looks wrong
Tell us which page and which number, and what you expected. If you can, say which file it came from. Please do not attach files unless we ask.
Delete your account
Email us from the address you sign in with. We will delete your account, your uploaded files and every figure made from them, and confirm by email. You can also clear a single store’s data yourself from the Upload page inside the app.
Anything else
Ideas, a marketplace file we do not read yet, or something confusing on a screen: all welcome. Before writing, the common questions may already have the answer.
