Last updated 5 August 2026. By using the Setsquare tools you agree to these terms.
Setsquare provides browser-based tools for engineers: diagram builders (cloud architecture, ER, sequence, state machine, user flow, API flow, org chart, mind map, Gantt, Venn, git branching, image callouts), developer utilities (JSON, Base64, UUID, JWT, timestamp, cron, regex, diff, hash) and a prompt engine. The tools run on your device. You may use them for personal and commercial work.
An account is optional and free to create. You are responsible for the security of the email account you sign in with. You may delete your account at any time by contacting us; see the Privacy Policy.
Some export formats and higher usage limits require a paid plan (weekly, monthly, or a one-time lifetime purchase). Prices are shown at checkout and charged in INR through Razorpay. A weekly or monthly plan grants access for its period and does not auto-renew unless stated at purchase. Refunds are governed by our Refund Policy.
Do not attempt to disrupt or reverse-engineer the service, abuse the sign-in or payment systems, resell access, or use the tools to produce unlawful, infringing, or harmful material. We may suspend or terminate access that does so.
You own everything you create with the tools. Because your work stays in your browser, you are responsible for saving and exporting it; we hold no copy and cannot recover lost work. You are responsible for having the rights to any image or data you load into a tool.
The Setsquare name, site, and software are ours or our licensors'. These terms grant you a licence to use the tools, not ownership of them.
The tools are provided "as is", without warranty of any kind. We do not guarantee they will be uninterrupted, error-free, or fit for a particular purpose.
To the maximum extent permitted by law, we are not liable for any indirect or consequential loss, or for lost work, arising from use of the tools. Where liability cannot be excluded, it is limited to the amount you paid us in the 12 months before the claim.
These terms are governed by the laws of India, and disputes are subject to the courts of India, without prejudice to mandatory consumer-protection rights you may have where you live.
We may update these terms; the date above shows the latest version. Continued use after a change means you accept it.
