ChargeGuard Privacy Policy
What ChargeGuard collects, what it doesn't, and the choices you have.
ChargeGuard is a battery monitor for iPhone and Apple Watch, 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 ChargeGuard app specifically.
What we collect
Nothing off your device. ChargeGuard reads your iPhone's battery level and charging state and displays them on your paired Apple Watch. That information stays between your iPhone and your Watch. We do not have servers that receive it, and we cannot see your battery, your usage, or your identity.
What we don't collect
- No account — ChargeGuard has no sign-up and no login.
- No personal information, contacts, location, or health data.
- No advertising identifiers and no tracking across apps or websites.
- No analytics that leave your device.
StoreKit & purchases
Premium 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 Premium features on your device.
Third-party SDKs
ChargeGuard 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 ChargeGuard collects no data off-device, there is nothing for us to retain or delete on a server. Battery readings live only momentarily on your devices and are not logged.
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. Premium is a one-time purchase, so there is no subscription to manage or cancel.
Children
ChargeGuard 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.
