Apneo — Privacy Notice
Last updated: 2026-08-14
Apneo has no accounts, no analytics and no third-party SDKs of any kind. Sessions stay on your device and sync only through your own private iCloud, and heart-rate readings are kept in a separate store that never syncs at all. Its App Store privacy label is ‘Data Not Collected’.
Nothing is tracked or collected
Apneo contains no analytics, no advertising, no crash reporting and no third-party SDKs — the project has no package dependencies at all, so nothing but Apple’s own frameworks runs inside it. Its privacy manifest declares no tracking, no tracking domains and no collected data types, on every platform it ships to.
Where your practice data lives
Your sessions, custom patterns, saved resonant pace and program progress are stored on your device and mirrored to your own private iCloud (Apple’s CloudKit private database), so they follow you between your own devices under your Apple Account. That is your storage — Kalmaro has no server and cannot see, read or access any of it. There is no sync switch inside Apneo: it follows your device’s iCloud settings, and falls back to storing everything locally when iCloud is unavailable.
Heart rate and Apple Health
On Apple Watch, Apneo reads your heart rate during a session and writes a Mindful Minutes entry to Apple Health when a session is long enough to count. On iPhone it reads four figures for the recovery trends — resting heart rate, heart rate variability, respiratory rate and blood oxygen — and writes nothing at all; those are read when you open the screen and are never stored by the app or sent anywhere. The heart-rate summary of a session is stored, but in a separate database on your device that is deliberately excluded from iCloud sync, so health readings never leave the device you measured them on. Apple asks for Health access itself, and Apneo works without it.
Showing a session on your Apple TV
Apneo can run a session on an Apple TV in the same room. The phone and the TV talk to each other directly across your local network, encrypted, with nothing of Kalmaro’s in between — which is why iOS asks for local network permission the first time. What travels over that link is the session: which pattern is running, its timing, and the name your device already advertises on the network. Your live heart rate is sent to the TV only if you turn that on. It is off by default and the app asks once, in plain words, before it is enabled.
The one network request
Apneo makes a single network request of its own, and only when you open Settings: it asks Apple’s public iTunes endpoint whether a newer version is on the App Store, so the About section can tell you. It sends nothing but the app’s own bundle identifier, runs at most once per launch and fails silently. Everything else that uses the network is a system service acting for you — iCloud sync of your own data, purchases through the App Store, and the direct link to an Apple TV.
Reminders
Practice reminders are scheduled on your device by iOS. Apneo has no push notifications and no server that could send one, and a reminder says only what you set it to say.
Purchases
Apneo is free to download, with every technique and both training tables included. Apneo Pro is offered as a subscription or as a one-time lifetime purchase, and unlocks the multi-week programs, the suggested-session coach, the recovery trends, the resonant-pace assessment and the custom-pattern builder. Purchases are handled entirely by Apple; Kalmaro never sees your payment details.
Deleting your data
Sessions, custom patterns, assessments, reminders and program progress can each be deleted inside the app, and deleting a session removes its heart-rate record with it. There is no single ‘delete everything’ button: removing the app deletes its databases from that device, and anything that had synced is removed through your iCloud settings.
Support
There are no accounts and no sign-in. If you email Kalmaro for support, that message and its contents are kept only in order to reply to you.
‘Data Not Collected’
Apneo’s App Store privacy label is ‘Data Not Collected’, and that is accurate: your own private iCloud is your storage rather than a collection point, health readings never leave your device, and there is nothing else keeping a record. If you have any questions about privacy, email Kalmaro at reveal email address, or see the main privacy policy.
