CycleBox
Your cycle, your device.
CycleBox keeps everything on your device. No accounts. No servers. No analytics.
If you choose to sync across devices, Apple's iCloud encrypts it so even Apple can't read it.
Post-Dobbs, post-FTC. The standard for cycle tracking has changed. We don't want your data, and we built CycleBox so we'll never be able to have it.
