Which of these can I actually download today?
Only Sip. It is on the iOS App Store and has been for a while. Sip Vino and Sip Water are built but not released — when a page here says "coming soon" it means there is no App Store listing to send you to yet, and we would rather say that than put up a dead button.
Do I need all three?
No. They are separate apps with separate jobs. Sip works on its own, the cellar in Sip Vino works on its own, and Sip Water does not even ask you to sign in.
Is it one account across the apps?
For Sip and Sip Vino, yes — they sign in against the same Delta Metrics account, so one profile and one deletion request covers both. Sip Water has no account system at all; its data lives on your device.
Which privacy policy applies to me?
Each app has its own, because they genuinely do different things. Sip's policy, Sip Vino's policy, and Sip Water's policy — the last one is short, because that app does not have a server to send anything to.
Do you sell any of this data?
No. We do not sell your data, we do not share it with advertisers, and we do not profile you across apps for advertising. Each policy lists the infrastructure providers involved for that specific app.
Is there an Android version?
Sip has an Android build in private beta; the other two are iOS only right now. Email [email protected] with the subject "Android" to get on the list.
