We built Anchor to be private by design. Your habits live only on your device — we never upload them.
Anchor – Tiny Habits ("Anchor", "the app", "we", "us", "our") is developed and operated by Buildr Studio, an independent app studio by Aditya Kumar. This Privacy Policy explains how we handle information when you use our iOS and Android application.
