This privacy policy explains how nKalai ("we", "us") collects, uses, and shares information when you use the mobile application Learn Greek with Evagelia (the "App"). This page is the single, governing privacy policy for the App.

Privacy point of contact: infonKalai@gmail.com
What We Collect
We aim to keep data collection minimal. In this App, we use Google services only for advertising and in‑app purchases. Specifically, we may process:
- Advertising data (Google AdMob): Android Advertising ID (AAID), app context, coarse location (when supplied by the ad platform), and ad engagement metrics strictly to serve and measure non‑personalized ads because the App is child‑directed.
- Purchase information (Google Play Billing): purchase tokens/receipts to deliver the “Remove Ads” entitlement and to prevent fraud.
- User‑provided support info: email address and the content of your message when you contact us for help.
We do not request or collect precise (GPS) location, contacts, photos, microphone, or camera data.
How We Use Data
- Provide and operate App features.
- Process in‑app purchases and manage entitlements (e.g., ad removal).
- Monitor and improve performance, safety, and reliability.
- Show advertising (see “Advertising & Analytics”).
- Comply with legal obligations and prevent fraud/abuse.
Advertising
The App uses Google AdMob to display ads. Because the App is child‑directed, we tag ad requests for child‑directed treatment and serve non‑personalized ads only. Interest‑based advertising and remarketing are disabled for such requests. AdMob may access the AAID and basic app/device signals solely to deliver, limit frequency, and measure ads.
- No third‑party RTB for child‑directed ads: Ad requests tagged for child‑directed treatment are not eligible for third‑party real‑time bidding.
- Opt‑out / reset: You can reset or limit the AAID from your device settings (Settings → Google → Ads).
- Remove Ads purchase: If you buy the one‑time “Remove Ads”, AdMob ads are disabled on that device/account combination.
Data Sharing
We do not sell personal data. We share data only with:
- Google services: Google AdMob (to serve non‑personalized ads in a child‑directed context) and Google Play Billing (to process in‑app purchases like “Remove Ads”).
- Legal compliance: to comply with law, enforce our terms, or protect rights, security, and users.
- Business transfers: if we are involved in a merger, acquisition, or asset sale, information may be transferred as permitted by law.
Retention & Deletion
Advertising data (AdMob): Ad-related data is handled and retained by Google according to Google’s own retention policies. We do not maintain separate ad‑tracking databases beyond aggregate reporting available in AdMob.
- Purchases: purchase tokens/receipts are kept for the life of the purchase and as needed for accounting, fraud prevention, and legal requirements.
- Support emails: retained up to 6 months after our last communication, then deleted unless we must keep them longer to resolve issues or comply with law.
You can request deletion of support communications and other directly controllable data by emailing us at infonKalai@gmail.com. Some records (e.g., purchase receipts) must be retained for legal or security reasons.
Security
We use industry‑standard safeguards to protect data in transit and at rest where applicable, restrict access to authorized personnel, and regularly review our practices. However, no method of transmission or storage is 100% secure.
Children’s Privacy
The App is directed to children and families. We do not knowingly collect personal information from children beyond what is necessary to support the App’s core functionality (non‑personalized advertising and purchase entitlement). Ad requests are tagged for child‑directed treatment and serve non‑personalized ads only. We do not request precise location, contacts, photos, or microphone data.
If you believe a child has provided personal information beyond the above, please contact us at infonKalai@gmail.com and we will delete it.
Your Choices & Rights
- Reset or limit the Android Advertising ID from device settings.
- Revoke ad consent (where available) from the App’s privacy or settings screen.
- Request access, correction, or deletion of your information by email at infonKalai@gmail.com.
International Transfers
Our service providers may process data in countries other than yours. Where required, we rely on appropriate safeguards permitted by applicable laws.
Changes to This Policy
We may update this privacy policy from time to time. We will post the new policy on this page and update the “Effective date” above. Material changes will be highlighted within the App where appropriate.
