Privacy Policy

Clash Of Stars by BlitzBrawl · Last updated: June 26, 2026

Clash Of Stars is a browser-based planet-conquest strategy game by BlitzBrawl. We collect only what we need to run the game's features — multiplayer, ratings, friends, and (optionally) saving your account across devices. This policy explains what that is and why.

Identity & Accounts

• Anonymous device identity (default). So you can keep your rating and friends without signing up, we generate a player id, a display name, and a device token stored on your device (a cookie on the .mobx.games domain plus browser storage). No personal information is required to play.
• Optional email. If you choose to connect an email address, we store it so you can restore your account on another device. We send one-time verification codes to that address. You can remove it by erasing your account (see "Your Choices").
• Discord (Discord version only). If you launch the game as a Discord Activity, we use your Discord account id, username, and avatar (provided by Discord via OAuth) as your in-game identity.

Gameplay Data We Store

To provide multiplayer, ratings, the leaderboard, and friends, our servers store:

• your player id, display name, and (if connected) email;
• your rating, win/loss and games-played counts;
• your friends list and recently-played opponents;
• temporary lobby and match records;
• gameplay analytics — session and match events (game start/end, matchmaking) tied to your player id, collected by our first-party BBAnalytics service (no advertising identifiers or IDFA — these are purely operational metrics);
• moderation reports — when you report another player, we store the reason, an optional note, and the player ids of the reporter and reported for manual review. Reports auto-expire after 90 days.

This data is stored on Amazon Web Services (AWS) databases hosted in the European Union (eu-central-1), with replicas in other AWS regions to reduce latency.

Multiplayer Connection Data

• Connection id — a temporary identifier used to relay signaling between players; discarded when the session ends.
• WebRTC data — SDP offers/answers and ICE candidates exchanged to set up a peer-to-peer connection; not stored.
• IP address — as with all WebRTC apps, your IP may be visible to peers in a direct connection. When the TURN relay fallback is used, your IP is visible to the relay provider (Cloudflare) but not to your opponent. Inside Discord, traffic is relayed and your IP is not shared peer-to-peer.

On Your Device

The game stores your preferences (volume, language, map size, difficulty, and similar cos_* keys) in your browser's local storage. This stays on your device and is not sent to us.

Advertising & Analytics

The version of the game published on the Poki portal (poki.com) shows advertising served by Poki, which may collect data as described in Poki's privacy policy. The version at clashofstars.mobx.games does not show ads.

The web, Discord, BlitzBrawl, iOS, and Android versions of Clash Of Stars use our own BBAnalytics service to collect first-party gameplay metrics (session events, game start/end, matchmaking). This service does not use advertising identifiers, cookies, cross-site tracking, or IDFA. Data is stored in EU AWS infrastructure and is deleted when you erase your account (see "Your Choices").

Third-Party Services

• Amazon Web Services — hosting, multiplayer infrastructure, and the account/ratings/analytics databases.
• Cloudflare — TURN relay servers for multiplayer NAT traversal.
• BlitzBrawl accounts service (mobx.games) — handles optional email sign-in and account restore.
• BBAnalytics — our own first-party gameplay-analytics backend (EU AWS, no third-party SDKs).
• Poki — advertising on the Poki version only.
• Discord — identity and delivery for the Discord version only.

These providers process connection metadata (such as IP addresses and timestamps) under their own privacy policies.

Your Choices & Rights

You can erase your account and all associated data at any time from within the game (Options → Account → Erase account). This deletes your player record, friends, block list, moderation reports (as target and reporter), matchmaking entry, gameplay analytics, and your account/email records from our accounts service. You can also request deletion by emailing gihad@mobx.app with your player tag.

Depending on where you live, you may also have rights to access or correct your data — contact us to exercise them.

Data Retention

Lobby and matchmaking records are short-lived and expire automatically. Moderation reports auto-expire after 90 days. Account, rating, and analytics data is kept until you erase your account.

Children's Privacy

Clash Of Stars is not directed to children under the age of digital consent in their country, and we do not knowingly collect personal information from them. No personal information is required to play.

Changes

We may update this policy from time to time. Changes will be posted on this page with an updated date.
