Privacy Policy

Last updated: August 12, 2026

Data We Collect

Sleep audio: with your permission, Driftly records sounds while you sleep (such as snoring or talking) so it can classify them on-device.

HealthKit data: with your permission, Driftly reads and writes sleep sessions and related metrics like heart rate through Apple HealthKit.

Device and usage data: basic device information and in-app usage data that help us maintain performance and reliability.

To generate your nightly sleep score, detect events, and power the Smart Alarm and insights inside the app.

To keep the app stable and reliable across devices and iOS versions.

We do not use your sleep audio or HealthKit data for advertising or share it with third parties for marketing.

Sleep audio is processed on your device and is never uploaded to a server — analysis happens locally on your iPhone.

HealthKit data is stored and protected according to Apple's iOS privacy model and your own Health permissions.

We apply sensible security practices to the limited data we do handle and keep third-party access to the minimum required.

Sleep audio and on-device analysis remain on your device and are removed when you delete a session or the app.

We retain only the minimal device and usage data needed to operate the service, and for no longer than necessary.

You can view, export, or delete your data at any time from within the app.

You can revoke microphone and HealthKit access at any time in iOS Settings; the app will stop collecting that data.

Because audio is processed on-device and not stored on our servers, deleting in the app removes it from your phone.

If you have any questions about this policy or your data, email us at support@driftly.co.in and we will get back to you.
