Privacy policy

Effective July 7, 2026 · Stillbox for iOS & watchOS

The short version

Stillbox collects no data. There are no accounts, no analytics, no tracking, no third-party SDKs, and no servers of ours that your data could reach.

What stays on your device

• Breathing sessions, streaks, and custom patterns are stored locally on your device.
• A tiny streak marker (last practice day and count) syncs through your own iCloud key-value storage so streaks survive reinstalls and device swaps. It is visible only to your Apple account; we never see it.

Purchases

There are none. Stillbox is free, with no subscription and no in-app purchases, so there is no payment data for anyone — us or Apple — to associate with you through the app.

What we never do

• No personal information collected, sold, or shared — we have nothing to sell or share.
• No advertising, no identifiers, no fingerprinting.
• No health data: Stillbox does not read or write HealthKit.

Changes & contact

If this policy ever changes, the update ships with the app and is posted here. Questions: [email protected].
