Renzi1000 Privacy Policy
Renzi1000 ("the app") is a literacy app for children. We put kids' privacy first: the app runs fully offline and collects or uploads no personal information.
Information we collect
None. The app has no account system and never asks for a name, email, phone number or any identity detail, nor does it access contacts, photos, location or other private data.
Local storage
A child's learning progress, mastery levels and quiz records are all stored locally via SwiftData, with iCloud sync disabled. This data is used only to show progress in-app and never leaves the device. Deleting the app removes all of it.
Read-aloud
Character pronunciation is generated locally using the system's built-in text-to-speech; no text or audio is ever uploaded.
What we don't do
- We do not collect, upload or sell any personal or usage data.
- We have no account and require no registration or sign-in.
- We integrate no third-party advertising, analytics or tracking SDKs.
- We include no in-app-purchase prompts or external ad links.
Children's privacy
The app is designed for children's learning and follows the principles for protecting children's online privacy. Because it collects no personal information, parents can let children use it independently with confidence.
Changes to this policy
If this policy changes, we will update this page and the "Last updated" date at the top.
