Why a comparison is more than a feature list
Many parental control apps promise similar things: limiting screen time, seeing location, approving apps. At first glance they seem interchangeable. The important differences often lie elsewhere: in who stores your family's very personal data, what the business model looks like and how the app feels for your child.
A parental control app processes location histories, usage times and family structures. This is data about minors that deserves special protection. That's why it's worth taking a close look before you put an app on your child's device.
The 10 criteria at a glance
1. Where family data is stored
Are location, rules and requests stored on the provider's servers or in storage that the family controls itself? The fewer central copies there are, the smaller the risk.
2. Funding
Are you paying with money or with data? Check whether the app is funded by a subscription or purchase, or whether advertising and data partnerships appear in the privacy policy.
3. Sharing with third parties
The privacy policy should clearly state who the recipients are. Watch out for wording such as “partners”, “advertising networks” or “analytics service providers”.
4. Analytics and advertising SDKs
Third-party software components in the app can send usage data to third parties. Apple's App Privacy details on the App Store give you a first indication.
5. Transparency for the child
Does your child know what data you see? Apps that work openly strengthen trust. Secretly reading along damages it.
6. Honest technical limits
On the iPhone, Apple only allows certain interfaces. Reputable providers say clearly what isn't possible instead of promising “complete monitoring”.
7. A say for the child
Can your child ask for more time or an app and give a reason? Requests instead of silent bans make rules understandable.
8. Media literacy
Technical limits help for a while. In the long run, your child needs knowledge about algorithms, advertising, scams and privacy.
9. Cost and cancellation
How high are the ongoing costs, is there a free trial, how do you cancel, and does the purchase cover the whole family?
10. Deletability
Can you delete your family data yourself? Are there clear deadlines after which old location data is removed automatically?

How Kydly answers these criteria
| Criterion | Kydly |
|---|---|
| Storage location | No family server of its own. Family data is stored via Apple CloudKit in the iCloud of the Kydly organizer; connected devices keep local copies. |
| Funding | Free basic features, Premium via Kydly Monthly (€4.99 per month after 7 free days) or Kydly Lifetime (€69.99 one-time). Prices in Germany. |
| Sharing with third parties | No selling of data, no advertising. Apple, as its own service, provides iCloud, Maps, Location Services and purchases. |
| Analytics and advertising SDKs | No analytics or advertising SDKs of its own in the app. |
| Transparency for the child | In their own view, your child sees what parents see. |
| Technical limits | Openly documented: no reading of messages, photos, keyboard input or calls; location is the most recently available one, not accurate to the meter. |
| A say for the child | Children ask for more time or an app and give a reason. |
| Media literacy | 15 topics with cards and quiz questions, without grades; answers are not reported to parents (Premium). |
| Cost and cancellation | Cancel in your Apple Account settings; both purchase options apply to the whole Kydly family. |
| Deletability | “Delete family & reset Kydly” in the app; location samples are cleaned up after seven days. |

Conclusion
Don't compare parental control apps only by the length of their feature list. What matters is privacy, the business model, honesty about technical limits and whether the app strengthens trust between you and your child. Take ten minutes to read the privacy policy and the App Privacy details on the App Store before you decide.
You can try Kydly in advance without real family data in the App Clip demo.

Read the section on recipients in the privacy policy and check the App Privacy details on the App Store page. Terms such as “advertising partners” or “Data Used to Track You” are clear indicators.
Is Kydly also available for Android?
