Coast is a calculator. Every projection, every chart, every Coast FI calculation runs in your browser, on your device. None of your inputs — basic pay, EPF corpus, age, target — are ever transmitted to any server, including ours.
We do not have user accounts. We do not require sign-up. There is no database storing your scenarios. The only place your numbers exist is in the browser tab you have open.
When you tap the share button, the URL contains your inputs encoded as parameters. That URL goes only where you send it (WhatsApp, email, etc). We do not see it. The recipient sees the same calculator with your numbers loaded — also entirely in their browser.
We use Vercel Analyticsto count anonymous page views and approximate device/region totals. It does not use cookies, does not track individuals, and does not record any of your calculator inputs. You can verify this on Vercel's public privacy documentation.
That's it. No emails. No newsletters. No retargeting. No data brokers. Nothing to opt out of, because nothing is being collected.
