Questions people ask about Splash and Apple Health
Is Apple Health cycle tracking private?
Apple says Cycle Tracking data synced to iCloud is end-to-end encrypted when you use two-factor authentication, and that Apple cannot read it. Data on the phone is encrypted when it is locked with a passcode, Touch ID or Face ID. It is a good private option on iPhone.
Can I import Apple Health data into Splash?
Yes. The Splash iPhone app connects to Apple Health, so cycle data and Apple Watch wrist temperature can flow in with your permission. The web app can also read an Apple Health export zip on your device, skipping everything that is not cycle data.
Does Apple Cycle Tracking work on Android?
No. Cycle Tracking is part of the Health app on iPhone and Apple Watch. If you or a partner use Android or a laptop, Splash works in any browser and as an Android app, and it can read cycle data you export from Apple Health.
What changed at the last review
- : Apple’s page (published 14 Sep 2026) lists a 12-month PDF export for healthcare providers, so the doctor-report row now shows it instead of a dash; Apple Watch models named; ovulation estimates are noted as available only in some regions.
