Adagio privacy policy
Last updated 16 September 2026
The short version
Adagio collects nothing. There is no account, no server of ours and no analytics. Everything you do in the app stays on your device.
What stays on your device
Your calibration answers, your level, which sessions you completed, your reminder times and your settings are written to the app's own storage on your iPhone and Apple Watch. We cannot see any of it.
What we collect
Nothing. No name, no email address, no device identifier, no usage statistics, no crash reports, no advertising identifier and no location.
Third parties
The app contains no third-party code, no advertising networks and no analytics services. It makes no network requests of its own: put the phone in airplane mode and everything still works.
Purchases
Purchases go through Apple's In-App Purchase system. Apple processes the payment and tells the app whether a purchase is active. We never see your payment details, and Apple sends us no personal data about you.
Notifications
Reminders are scheduled locally by your own device. They are never sent from a server, and their wording never names what the app is for.
Health data
Adagio does not read from or write to Apple Health.
Children
Adagio is not directed at children, and it collects no data from anyone of any age.
Deleting your data
Delete the app; everything goes with it. There is no copy anywhere else, and nothing for us to erase on request.
Changes
If this policy ever changes, the date above changes with it. A version of Adagio that collected data would be a different product, and we would say so plainly.
