Last updated 5 August 2026. This covers the Setsquare suite at setsquare.pages.dev, the drawing and diagram tools, the developer utilities, the Cloud Architecture Builder, the ER Diagram Builder, and the Prompt Engine.
The tools run entirely in your browser. The diagrams, schemas, images, code and text you work on stay on your device, in memory and your browser's local storage, and are never uploaded to us. There is no sign-up and nothing to buy, so we ask you for no personal data at all. We run no advertising or analytics trackers.
Your work product, every diagram, schema, screenshot, generated prompt and exported file, is never sent to our servers. There is no server-side copy of it, so we cannot read it, share it, or recover it if you lose it. We use no advertising networks, no analytics/telemetry SDKs, and set no tracking cookies.
Server logs, and nothing else: to keep the service secure and available. There is no other personal data for us to use. We do not sell personal data or use it for advertising.
Work product stays in your browser until you clear it. We keep no account or purchase records, because there are none. Server logs rotate on our host's normal schedule. You can clear your browser's local storage and cookies at any time from your browser settings.
To be precise: we use only strictly necessary and functional browser storage, and we set no advertising or analytics cookies and run no trackers. Because nothing we store is used for tracking or profiling, there is no consent banner, and none of this storage requires your consent under the GDPR or DPDP Act. What we store is:
The full itemised list is in the Cookie & Local Storage Policy. You can clear all of it from your browser settings at any time.
Under the India DPDP Act 2023, the EU/UK GDPR, and similar laws, you may ask us to access, correct, delete or export the personal data we hold about you. In practice we hold none: there is no account, and your work never leaves your device, so there is nothing for us to return or erase. To exercise any right, or to check that for yourself, email arjunmnair0303@gmail.com; we respond within 30 days.
The tools are not directed at children under 13, and we do not knowingly collect their data.
If this policy changes materially we will update the date above and note it on the site.
