The shortest privacy policy you'll read this year, because we collect almost nothing.
Everything you do in SkyCalm (your flight phase, checklist ticks, flight log, unlock state, access code) is stored only on your device, in your browser's local storage. It never leaves your phone. We run no accounts, no analytics inside the app, no tracking pixels, and no third-party SDKs.
Purchases are processed by Stripe (stripe.com), which handles your payment details under its own privacy policy. We receive the order confirmation, not your card number. If you bought SkyCalm on Google Play, Google processes the payment instead and the same principle applies.
Our web host (Cloudflare Pages) keeps standard, short-lived server logs, and Stripe shows us completed orders so we can honor the 30-day refund guarantee. That is the complete list.
SkyCalm is built to work in airplane mode. Once installed, it makes no network requests at all, which is both the product promise and the strongest privacy guarantee software can make.
Reply to your Stripe receipt email within 30 days for an unconditional refund. That email thread is also the support channel.
