One of Billions · RonaiLabs
Privacy policy
Effective: 9 November 2026Who we are
One of Billions is an iOS life simulation operated by RonaiLabs. This policy explains the app and its supporting services. It is independent of the 1in8b website. Privacy contact: my.yuce.mahmut@gmail.com.
Game data and service operation
We create a random service identifier and store an authentication credential in your device Keychain. Our Cloudflare backend stores the identifier, simulated lives, choices, selected simulation language, session state and operation records so you can play and resume. Simulation parameters and decisions are sent through our server to the 1in8b Engine. Character names, countries and life events are fictional game data, not a request for your real identity. Network providers process IP addresses and technical request data to deliver and secure the service; rate limiting uses a derived identifier.
Information kept on your device
Settings and a local life archive are stored on the device. The birth-date calculator processes the date you enter on your device; our app does not send that date or your calculated birth rank to the Engine, advertising services or our backend. Public population data is downloaded separately. A card you choose to share is passed to the service you select; its recipient may receive the information shown on the card.
Advertising and optional Meta measurement
Google AdMob and its User Messaging Platform support opening ads and privacy choices. Google may process IP-derived approximate location, device or advertising identifiers, ad impressions and interactions, and diagnostic or performance data. Availability and personalisation depend on your region, consent and device permissions. Our app does not request precise location. Meta measurement is off by default and starts only after you enable it in Settings and authorise Apple tracking permission. It sends app activation and successful new-life-start events, with SDK technical data and permitted identifiers. We do not attach your birth date or simulated character details. Turning the option off stops new app-triggered Meta events; it does not delete earlier records held by providers.
Purchases
The development version uses RevenueCat Test Store to prepare subscriptions; real purchases are not yet enabled. RevenueCat processes a pseudonymous identifier and test transaction status. When Apple purchases are enabled, Apple handles payments; transaction identifiers, products, receipts and subscription status are processed to verify access and restore purchases. We do not receive your full payment-card number. We update this policy when the integration changes.
Providers, purposes and international processing
We use Cloudflare for hosting, security and database services, 1in8b for simulation, Google for ads and consent, and Meta for optional advertising measurement. These providers may process data in countries other than yours, including the United States. Their policies explain their processing and safeguards. Where applicable, processing relies on providing the service you request, security and legitimate operational interests, legal obligations, or your consent for optional tracking and advertising where required. We do not sell simulated life records or birth dates to advertisers.
Retention and security
Local records remain until removed from the device or app storage; Keychain credentials may survive reinstalling the app. Server identifiers, life history and operation records currently have no fixed automatic deletion schedule. Session-token expiry does not delete archived lives. We retain service records for continuation and support, subject to verified deletion requests and legal or security needs. We use encrypted network transport, hashed service credentials and encrypted Engine session tokens. Provider retention and backup schedules can differ.
Your choices and privacy requests
You can change Meta measurement in app Settings, manage tracking permission in iOS Settings, and use the app’s advertising privacy options when available. You may request access, correction, deletion, restriction, portability or object to processing, subject to applicable law; you may withdraw consent without affecting earlier lawful processing and complain to your local authority. Write to my.yuce.mahmut@gmail.com. Because accounts are pseudonymous, we may need limited information to locate and verify your records; never email your authentication credential. Uninstalling alone does not erase server records. Contact us if you need help identifying them.
Children and changes
The app is not designed for children under 13 or a higher minimum age required where they live. If you believe a child has provided personal information, contact us. We update this page when our data practices change; the effective date identifies this version. Visiting this policy page does not enable app tracking. This page contains no advertising, analytics scripts or non-essential cookies; hosting infrastructure still processes technical requests.
