Privacy Policy

This policy explains how SiderealWeb and the SiderealWeb Companion browser extension handle data. SiderealWeb is a web exploration game. The companion extension adds an optional immersive navigation layer when a player opens a destination from the game.

Information we process

Account and gameplay information

If you create an account, SiderealWeb may process account identifiers such as your email address, public username/gametag, wallet/game balances, owned ships, routes, named planets, visits, favorites, level, XP, ranking information, and other gameplay state needed to operate the game.

Payments

Payments are processed by Stripe. SiderealWeb receives payment status and product information needed to credit Space Coins or purchases. SiderealWeb does not receive or store full card numbers.

Extension session data

The SiderealWeb Companion extension stores temporary session context in the browser, such as the destination URL opened from SiderealWeb, return tab information, selected ship visuals, and route context. This lets the extension display the overlay and return the player to the game tab. This context is cleared when the destination tab is closed or the return flow ends.

What the extension does not do

• It does not sell personal data.
• It does not collect passwords, payment card numbers, or form contents from destination websites.
• It does not read your browsing history for advertising or profiling.
• It does not transmit the content of third-party pages to SiderealWeb.

Why the extension requests broad website access

The extension needs access to opened web destinations so it can draw the ship overlay, simulate the ship cursor locally, and provide the return-to-game control. The overlay is activated for destinations opened through SiderealWeb's portal flow. The permission is for the immersive browser experience, not for harvesting page content.

Third-party services and destinations

SiderealWeb may use third-party services for authentication, database storage, payment processing, hosting, and search/destination discovery. When you open an external destination, that destination is controlled by its own operator and its own privacy policy.

Data retention

Gameplay records, named planets, routes, purchases, and account state may be retained while your account exists, because they are part of the persistent shared universe. Temporary extension session context is designed to be short-lived and local to the browser session.

User choices

• You can use the website without the companion extension, with a less immersive experience.
• You can remove the extension from your browser at any time.
• You can sign out of the website to stop account-based gameplay updates on that device.
• You can clear local browser storage; this may remove local navigation state, but server-side account progress remains tied to the account.

Children

SiderealWeb is not designed to knowingly collect personal information from children under the minimum age required by applicable law. The game includes a moderation filter for destinations, but external web results can still fail. Users should treat external destinations as the open web, not a sealed playground.

Contact and support

For support or privacy requests, use the support contact shown in the Chrome Web Store listing for SiderealWeb Companion, or visit the Support page.

The moderation filter is intended to reduce obscene or illicit destinations. It can fail, and it may be improved over time when failures are found.
