How parental apps work on the iPhone
Apple provides developers with three core building blocks for parental features: authorization through Family Sharing, interfaces for setting rules on the child's device, and device usage reports that are displayed in a protected area. On top of that come Location Services and iCloud for syncing.
This architecture also protects children from the apps that are supposed to protect them: a lot of data stays on the device, and apps don't see everything that happens on the iPhone.
What is possible
- Block or limit apps and categories at certain times
- Restrict web content, app installation and purchases
- Show usage times in a protected report
- Share the most recently available location with its accuracy
- Trigger notifications when entering or leaving zones
- Sync requests and approvals between family devices
What isn't possible
- Reading messages, chats or keystrokes
- Secretly analyzing call logs, the microphone or the camera
- Making screen recordings without the user noticing
- Selecting apps remotely: Apple only allows app selection on the child's device
- Guaranteed instant location notifications or live location accurate to the meter
- Reliably detecting that an iPhone has been turned off
- Intercepting every App Store purchase
Apps that promise more often work with device management profiles, workarounds via a computer or simply with exaggerations. Look at such promises critically.
How Kydly deals with these limits
- Rules only take effect once the child's iPhone syncs them and applies them locally. Without a connection, the most recently loaded rule stays active.
- Screen Time is not a live ticker. The numbers come from Apple's protected reports; Kydly does not read the raw data.
- The location is the last known position with its accuracy. If the iPhone is off, Kydly shows the time of the last check-in.
- App installations can be restricted; approved installations continue to go through Apple's Ask to Buy.
We deliberately spell out these limits so that you know what you can rely on and where a conversation with your child matters more than any technology.

Frequently asked questions
Can an iPhone app read my child's WhatsApp messages?
Not through Apple's official interfaces for parental features. Kydly does not read messages.
Why do I have to select the apps on the child's device?
For privacy reasons, Apple only allows the affected apps to be selected on the child's device. Use the moment to discuss together which apps fall under which rule.
Does Kydly work on the iPad?
Kydly is built for the iPhone. You can find current compatibility information on the App Store page.
