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.
There are no accounts. Nothing asks you to sign up, and we store no profile of you; see the Privacy Policy.
Everything is free. Every tool, every export format and every feature is open to everyone, with no plans, no subscription and no payment taken on this site.
Do not attempt to disrupt or reverse-engineer the service, 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.
You agree to indemnify and hold harmless Setsquare and its operator from any claim, loss, liability, or expense (including reasonable legal fees) arising from your use of the tools, the content you create or load into them, your breach of these terms, or your violation of any law or third-party right, except to the extent it is caused by our own gross negligence or wilful misconduct.
These terms are governed by the laws of India. Before starting any formal proceeding, contact us at arjunmnair0303@gmail.com and give us 30 days to resolve the matter informally.
Except where the law where you live gives you a non-waivable right to use your local courts or a consumer forum, any dispute that is not resolved informally will be settled by binding arbitration before a single arbitrator under the Arbitration and Conciliation Act, 1996, seated in India and conducted in English. Either of us may still seek urgent injunctive relief from a court for misuse or intellectual-property infringement, and either of us may bring a qualifying claim in a small-claims or consumer forum.
Class-action waiver. To the extent permitted by law, disputes will be resolved on an individual basis; you and we waive any right to bring or take part in a class, collective, or representative action. If this waiver is held unenforceable for a particular claim, that claim proceeds in court, but the rest of this section still applies. Nothing here removes mandatory consumer-protection rights you may have where you live.
We are not liable for any delay or failure to provide the tools caused by events beyond our reasonable control, including outages of our hosting, network, or third-party providers, acts of God, fire, flood, epidemic, war, civil unrest, labour disputes, or government action.
If any provision of these terms is held invalid or unenforceable, it will be limited or removed to the minimum extent necessary and the remaining provisions stay in full effect. Our failure to enforce a provision is not a waiver of it. These terms, together with the Privacy Policy, the EULA, and the other policies linked from them, are the entire agreement between us about the tools and supersede any prior understanding.
We may update these terms; the date above shows the latest version. Continued use after a change means you accept it.
