Privacy Policy
In short: CentoZeri collects nothing. There is no account, no advertising, no analytics, and the App works entirely offline — it never sends any data anywhere.
CentoZeri ("the App") is an educational journey that takes children — and curious adults — from the number 1 all the way to infinity. It was built for children, so we built it to collect nothing at all. This page explains, clearly and honestly, how the App handles data.
No Data Collected
We do not collect, store, or transmit any personal data. The App does not ask for your name, email, age, or any other personal detail, and it does not create a user profile.
No Account
You do not need to register or sign in to use CentoZeri. There is no login of any kind.
The App Works Offline
CentoZeri contains no networking code: it does not connect to the internet, and it has no servers of ours to connect to. All content — the journey, the games, the experiments — is contained inside the App itself. The only exception is the purchase, which is handled by Apple (see below).
What Stays on Your Device
The App remembers how far along the journey you have travelled, and whether the optional purchase has been made. This information is stored only on your device, is never transmitted, and is removed when you delete the App.
No Advertising
CentoZeri contains no advertising and no advertising identifiers. No third party receives any information about you through the App.
No Analytics or Tracking
The App uses no analytics, no tracking tools, and no third-party software development kits of any kind.
Purchases
The optional "Oltre il Googol" purchase is handled entirely by Apple through the App Store via StoreKit. We never see or store payment information: your purchase history is managed by your Apple ID. Purchases are protected in the App by a check designed for adults.
Third-Party Services
The App relies on a single third-party service: Apple StoreKit, used only to handle the in-app purchase. Your use of it is subject to Apple's Privacy Policy. There are no other third-party services, and no advertising or analytics providers.
Children's Privacy
CentoZeri is designed for children and collects no data from anyone, including minors. There is no advertising, no analytics, no account, no chat, no user-generated content, and no way for a child to communicate with anyone through the App. Purchases and any links that leave the App are placed behind a check intended for adults. If you have any concern about children's privacy, please contact us at the address below.
Your Rights (GDPR)
If you are located in the European Economic Area, you have the right to access, correct, delete, restrict, port, and object to the processing of your personal data. Because we hold no personal data at all — nothing leaves your device — there is nothing for us to access, export, or erase. Deleting the App removes everything it has stored. For any question, contact us below.
Security
Since no data is transmitted or stored on any server of ours, there is no data in transit or at rest for us to protect. Everything the App creates remains within the App's private storage on your device, protected by iOS.
Changes to This Policy
We may update this Policy to reflect changes to the App. When we do, we will update the "Last updated" date at the top of this page. Continued use of the App after changes are posted constitutes your acceptance of the revised policy.
