Privacy Policy

Last updated: October 5, 2026

Nerve Arena is operated by Nikola Zorbić, a sole proprietor based in Petrovaradin, Serbia ("we", "us" or "our"), who is responsible for your personal data. This policy explains how we collect, use and protect your information when you use the Nerve Arena apps for iOS and Android, the web version of the app and this website (together, the "Service").

Information We Collect

Account data: To use the Service you sign in with Google or Apple. We receive your name, email address and provider user ID from the chosen provider. We use this to create your account, which stores your progress, match history, stats and journal entries. Where available on the web, you can try a practice fight before signing in; we create a temporary anonymous session for it, which is deleted after 30 days unless you sign in, in which case it becomes part of your account.

Your content: What you write or say in practice fights, your journal entries and the scenarios you create are stored with your account and processed by our AI provider (Google Gemini) to generate replies, scores and feedback.

Microphone access: Voice conversations in the iOS and Android apps need access to your device's microphone. Audio is used solely to power the conversation and its transcription through Google Gemini. We do not store raw audio files on our servers after processing.

Usage data: The iOS and Android apps collect information about how you use them via Firebase Analytics (screens visited, features used, session duration), which we look at in aggregate. The web version uses Google Analytics (via Firebase) only if you allow it in the consent banner; nothing is collected if you decline. To change your choice later, clear this site's data in your browser and the banner will ask again.

Security checks: The web version uses Google reCAPTCHA Enterprise through Firebase App Check to confirm that requests come from our genuine app and to prevent abuse. It collects technical information about your browser and device, which Google processes under its own terms.

Purchase data: Purchases are made in the iOS and Android apps and processed by the Apple App Store or Google Play, which handle your payment details under their own terms; we never receive your card details. Nothing can be bought in the web version: a subscription bought in either app also unlocks it there. RevenueCat keeps track of your subscription status across the apps and the web. We store a record of your purchases solely to provide what you bought.

Device data: The apps send crash reports via Firebase Crashlytics to improve stability. Reports include device model, OS version and app version. No personally identifiable information is included.

Browser storage: The web version keeps your settings (such as theme and your analytics choice) in your browser's local storage. If you allow analytics, Google Analytics also sets cookies. This website, nervearena.com, uses no analytics or advertising cookies. It loads fonts from Google Fonts, which receives your IP address to deliver them, and if you dismiss its offer to show a page in your language, it remembers that in your browser's local storage.

How We Use Your Information

Data Sharing

We do not sell your personal data. We share data only with:

Advertising

Free-tier users of the iOS and Android apps may choose to watch rewarded video ads to earn Resolve. Ads are provided by Google AdMob. When you consent, AdMob may collect:

Ads are never shown to paid subscribers and never shown on the web. Ads are never forced: you see one only when you choose Watch a Short on the Resolve refill screen. On iOS, the system App Tracking Transparency prompt is shown before any tracking occurs. In GDPR regions, Google's consent form is shown.

For details, see Google's ad partner policies at policies.google.com/technologies/partner-sites and the AdMob privacy disclosure at support.google.com/admob/answer/6128543.

Data Retention

Your data is retained as long as your account exists. You can delete your account at any time. In the apps, open the Self tab, tap the gear icon to open Settings and tap Delete Account; on the web, open Settings and choose Delete Account. Then type DELETE and confirm with Delete forever. Deletion removes your account and the data linked to it, such as your profile, stats, match history and journal entries, from our active databases; our account deletion page lists what is deleted and the little that is kept. If you cannot use either option, email hello@nervearena.com. Inactive accounts may be purged after 12 months of inactivity. Apple and Google keep their own records of purchases made through them, as the law requires.

Children

The Service is not directed at children under 13. We do not knowingly collect personal information from children under 13.

Your Rights

Depending on where you live, you may have rights to access, correct, delete or export your personal data, and to complain to your local data protection authority. Contact us at hello@nervearena.com to exercise these rights.

Changes to This Policy

We may update this policy from time to time. We will notify you of significant changes by updating the "Last updated" date above.
