Fast Tracker
Intermittent fasting, tracked on your phone and nowhere else. Fasts, goals, streaks and history live in a local database — there is no backend to hold them. iOS, Android and Wear OS.
Privacy is the seed, not the trim
Before we write a line of code for any app, we start with one question: how can we design this so it respects the people using it, from the foundation? That question is not a checkbox we tick before shipping, or a setting buried three menus deep. It is the first decision we make, not the last.
On device
Where an app needs data to work, that data stays on your phone. It is never transmitted to us, and we hold no server-side record of it.
No trackers
No analytics, no advertising SDKs, no third-party tracking libraries of any kind. There is no consent banner because there is nothing to consent to.
Nothing to leak
No personal data reaches our servers, so there is no user database that can be breached. The strongest protection is not collecting it.
Apps
Four apps, one design rule: your data stays on your device.
Period Vault
Menstrual cycle tracking that never leaves your phone. Fully offline, zero telemetry, and every backup encrypted with AES-256-GCM — there is no server to send one to. iOS and Android.
Watch Cast 4 Me
Podcasts and audio on your wrist, with genuine offline playback. Plays from RSS, the Files app, iCloud Drive, Audiobookshelf or Jellyfin. Apple Watch.
Wisdom Notifications
Good ideas, resurfaced. Reminders that arrive on your schedule and never leave your device. Works with the network off, because it never needed it on. iOS and Android.
What that means in practice
Six claims, each one falsifiable. The privacy policy is the long version.
Stays on your device
Where an app needs data to work, that data stays on your phone. It is never transmitted to us, and we hold no server-side record of it.
No trackers, ever
No analytics, no advertising SDKs, no third-party tracking libraries of any kind. There is no consent banner because there is nothing to consent to.
Nothing to sell
We have no user data, so we have nothing to share, sell, rent or trade. Not now, and not if the incentives change later.
Nothing to breach
No personal data reaches our servers, so there is no user database to leak. The strongest protection is not collecting it.
No account needed
Nothing to sign up for and nothing to log into. We could not build a profile of you even if we wanted one.
A data request comes back empty
Under GDPR or CCPA you can ask us what we hold about you. The honest answer is nothing, and we would rather say so plainly.
