Privacy Policy

Last updated: 31 August 2026

Calypso does not collect, store, transmit, or share any personal data, with anyone, for any purpose.

What Calypso stores

The only information Calypso uses is what you enter yourself — your date of birth and your display preferences (which time periods to show, decimal precision, and similar settings). This is stored only on your own device, in a private app data container. If you use iCloud to sync data between your own devices, that sync happens through Apple's own iCloud service, not through us — we never see it, and Calypso has no server of its own to send it to even if it wanted to.

What Calypso does not do

• No accounts, no sign-in, no passwords
• No analytics or usage tracking
• No advertising or ad networks
• No third-party SDKs of any kind
• No network requests — Calypso works entirely offline

Deleting your data

Uninstalling Calypso removes everything it stored. There is nothing left behind on any server, because there was never a server in the first place.
