MicroNations: City Builder · OmniAlera Gaming Division · Last updated: 19 September 2026

Who we are

OmniAlera Technologies Holdings Inc. ("OmniAlera", "we", "us") operates MicroNations: City Builder, available at micronations.omnialera.com and on Google Play. Questions? Email privacy@omnialera.com.

What data we collect

• Account identifier. A Firebase Authentication UID — anonymous or linked to your Google account email address.
• Display name. The name you choose to show on the leaderboard (up to 40 characters).
• Gameplay state. Your nation's resources, buildings, score, level, motto, capital, ruler title, custom flag, relations with the game's computer-run neighbours and your nation's Chronicle, stored at nations/{uid} in Firebase Firestore.
• Public nation page. Other players can visit your nation from the leaderboard or a link you share. The page shows only your nation's name, flag, motto, capital, ruler title with the first word of your display name, your buildings (to draw the city), rank, population, happiness, score and a few lines of its Chronicle. It never shows your resources, email, account or payment details.
• Game Passport. Your age bracket, goal, and subscription tier, stored at users/{uid}.
• Leaderboard entry. Your display name, nation name and flag, score, level, population, happiness, Emperor title (if you hold Empire Pass) and your continent-level region at leaderboards/micronations/scores/{uid}. This data is publicly readable.
• Progress. Achievements, daily mission streak and lifetime game stats at activity/{uid}, so they follow you across devices.
• Invitations. If you invite friends or join through an invite link, your invite code and whether a reward was paid, at referrals/{uid}.
• Usage statistics (optional). Counts of in-game actions such as "building placed" or "mission completed", tied to a salted one-way hash of your account ID rather than the ID itself, plus the days you played and your country (derived from your IP address by our host, not stored as an IP). Used to understand what players enjoy and how many return. Turn it off anytime in Settings → Privacy.
• Reminder token (optional). If you switch on daily reminders, a push-notification token from your browser and your time-zone offset, at _pushTokens/{uid}, used only to send at most one reminder a day. Switching reminders off or deleting your account removes it. Notifications are delivered by Google Firebase Cloud Messaging.
• Language and device settings. Your chosen Griot language, sound, vibration and similar preferences are stored only in your browser. The language is sent with AI requests so replies come back in that language.
• Error reports. If the game crashes, a short technical report (error message, game screen, app version, browser type) — no personal data.
• Trade offers. Resource trade offers you post at tradeOffers. Your UID appears as the fromUid field.
• Subscription records. If you purchase Premium or Empire Pass, Stripe stores your payment method and billing details. We store your Stripe customer ID and subscription status in Firestore. We never see or store your card number.
• Notification preference. Whether you opted into daily mission reminders, stored only in your browser's localStorage. We do not receive this on our servers.

We do not collect your precise location, device identifiers, or browsing history outside this game. We do not use advertising or third-party trackers, and we do not set cookies.

How data is stored

All game data is stored in Google Firebase Firestore, project micronations-88e2d, located in the United States. Firebase is operated by Google LLC under their Terms of Service and Privacy Policy. Payment processing is handled by Stripe, Inc. under their Privacy Policy.

How we use your data

• To save and restore your game state across sessions and devices.
• To display your score on the public leaderboard.
• To fulfil and manage your subscription (Premium or Empire Pass).
• To generate AI-powered game content (the Griot, crisis events, advisor, diplomacy) via Anthropic's Claude API, with OpenAI as a backup if Claude is unavailable. Your nation's game state and any question you type to the Griot are sent to the provider for that request only; we do not store your questions.
• To prevent abuse (for example, rate limits keyed to your account and network) and to keep the game reliable.

We do not sell your data to third parties. We do not use your data for advertising.

Data retention

Your data is retained until you delete your account. You can delete it instantly in the game under Settings → Account → Delete my account, or ask us by email — see our data deletion page. Email requests are completed within 30 days.

Your rights

Depending on your jurisdiction, you may have the right to access, correct, or delete your personal data. Contact privacy@omnialera.com to exercise these rights.

Children

MicroNations: City Builder is not directed at children under 13. We do not knowingly collect data from children under 13. If you believe a child has provided us data, email privacy@omnialera.com and we will delete it promptly.

Changes to this policy

We may update this policy from time to time. The current version is always at micronations.omnialera.com/privacy.html. Continued use of the game after a change constitutes acceptance of the updated policy.
