Pulse is a single-value watch-face monitor, published by ZEN LABS S.R.L. (Bucharest, Romania). It is built to do one thing well without harvesting your data. This policy describes the data practices of the Pulse app specifically.
What we collect
We operate no server in the path. Pulse displays a value that you push to it from your own webhook. That value travels from your server through Apple's Push Notification service (APNs) to your device. We never see, receive, or store the value or your endpoint — you control entirely what you send and when.
What we don't collect
- No account — Pulse has no sign-up and no login.
- No personal information, contacts, or health data we receive.
- No advertising identifiers and no tracking across apps or websites.
- No analytics that leave your device.
Push notifications
Delivery uses Apple's Push Notification service. Apple handles transport per its own policies; the payload is the value you choose to send. Disable notifications in iOS Settings at any time.
StoreKit & purchases
Pulse is a one-time in-app purchase sold through Apple. When you buy it, Apple processes the payment via your Apple ID using StoreKit. Apple handles your payment details — we never receive or store your card information. We receive only the anonymous transaction status needed to unlock the app on your device.
Third-party SDKs
Pulse ships without third-party analytics, advertising, or tracking SDKs, and it does not share any data with third parties — including third-party AI services. If we ever add a diagnostics or crash-reporting tool, we will update this policy and the App Store privacy label before it ships, disclose exactly what it collects, and ask for your consent where required.
Data retention
Because Pulse collects no data off-device, there is nothing for us to retain or delete on a server. On-device data lives only on your devices and is removed when you delete the app.
Your choices
You can turn off notifications in iOS Settings at any time, remove the Watch complication, or delete the app — which removes all of its on-device data. Pulse is a one-time purchase, so there is no subscription to manage or cancel.
Children
Pulse is not directed at children and collects no personal information from anyone.
Changes
If this policy changes, we'll revise the "last updated" date above and, where the change is material, note it in the app's release notes.
