This Privacy Policy explains how ZeroUp Developers ("we", "us") collects, uses and protects information when you use any of our mobile applications published on Google Play (the "Apps"). It applies to every application listed on our apps page.
In short: we do not sell your personal data. We collect the minimum needed to run the Apps, keep your learning progress, and show advertising that keeps the content free.
We do not collect your precise location, contacts, photos, microphone input, or any special-category personal data.
Our Apps rely on the following services, each of which processes data under its own privacy policy:
| Service | Purpose | Policy |
|---|---|---|
| Google AdMob and its mediation partners |
Serving and measuring advertisements | Ads policy |
| Google Firebase (Authentication, Firestore, Messaging, Analytics) |
Sign-in, progress storage, notifications, usage analytics | Firebase privacy |
| Google Play Services | App distribution, updates and integrity | Google privacy |
Advertising partners participating in AdMob mediation may collect an advertising identifier and limited device signals in order to select and measure ads. They act as independent controllers of that data under their own policies.
Advertising keeps our learning content free. Ads are shown as banners, interstitials, native placements and rewarded videos. Rewarded videos are always optional — you choose whether to watch one in exchange for an in-app benefit.
You can reset or delete your advertising identifier, or opt out of personalised advertising, from your device settings under Settings → Google → Ads.
Before any ad is requested, our Apps present a consent message through Google's User Messaging Platform (UMP), a certified Consent Management Platform. You may accept or decline personalised advertising, and you can change your choice later from the App's settings screen. If consent is declined, we serve non-personalised advertising only.
Where the GDPR applies, we process personal data on the following bases: performance of a contract (providing the App you requested), consent (personalised advertising and optional notifications), and legitimate interests (security, crash diagnostics and product improvement).
Account and progress data is retained while your account remains active. If you delete your account, associated data is removed from our production database within 30 days. Aggregated, non-identifying analytics may be retained for longer.
To exercise any of these rights, email zeroupdevelopers@gmail.com. We respond within 30 days.
Our Apps are not directed to children under 13, and we do not knowingly collect personal data from them. If you believe a child has provided us with personal data, contact us and we will delete it.
Data is transmitted over encrypted connections (HTTPS/TLS) and stored on Google Cloud infrastructure with access restricted to the studio. No method of transmission or storage is perfectly secure, and we cannot guarantee absolute security.
Our service providers operate globally, so your data may be processed on servers outside your country of residence, including in the United States, under the safeguards those providers maintain.
We may update this policy from time to time. Material changes will be announced in the App or on this page, and the "Last updated" date above will be revised.
