Nothing. CLOCK has no accounts, no sign-in, no analytics, no advertising, no crash reporting, and no third-party SDKs. The app does not send any data off your device. There is no server. It works in airplane mode because nothing it does requires the internet.
Your sessions, timers, clients, and invoices are stored locally on your device, and nowhere else. If you delete the app, that data is deleted with it. We could not read your invoices if we wanted to; they never leave your phone or computer.
When you send an invoice, CLOCK hands the PDF to your device's share sheet (Messages, Mail, AirDrop, or whatever you pick). From that point the delivery is handled by the app you chose, under its own privacy policy. CLOCK itself transmits nothing.
The iPhone app is sold through Apple's App Store; Apple processes the payment and we never see your payment details. The Mac app is sold through Lemon Squeezy, which processes that payment under its own privacy policy; we receive only what is needed to deliver your license.
CLOCK collects no data from anyone, including children.
If a future version of CLOCK ever changes any of the above, this page will say so before that version ships, and the App Store privacy label will be updated to match.
