Terms of use
Last updated: 14 October 2026
Early access
SimpleSankey is in early access (beta). It is free to use for now. Features may change, and some features may become paid in future. We will not charge you for anything without asking you first.
Using SimpleSankey
You may use SimpleSankey for personal, educational and business purposes, and you own the diagrams and project files you create with it. Please do not misuse the site, try to break or overload it, or copy or resell the SimpleSankey software or website.
Your data and your files
Your diagram data stays in your browser and on your device (see our privacy notice). That means we cannot back it up or recover it. There is no autosave, so please use Save to keep a project file, and keep your own backups. Closing or refreshing the page can lose unsaved work.
No guarantees
SimpleSankey is provided "as is" and "as available", without any promise that it will be error-free, always available, or suitable for a particular purpose. Check any diagram you publish or rely on, including its numbers and layout. To the extent the law allows, we are not responsible for losses caused by using, or being unable to use, SimpleSankey. Nothing in these terms limits any rights you have by law that cannot be limited.
Ownership
The SimpleSankey name, website and software are © 2026 SimpleSankey. All rights reserved.
Changes and contact
We may update these terms and will change the date above when we do. Questions or feedback: [email protected].
