Beast of Burden Studios: Privacy Policy and Terms of Service

Beast of Burden Studios · Last updated: October 5, 2026

This single policy covers every Beast of Burden Studios game, rather than a separate document per title (it previously covered Umbral Idle: Last Salvage only; this page's URL still says "Project-ISO," that game's working title, for that reason, and every existing link to it keeps working). Shared sections (Consent, Your Rights, Children's Privacy, Security, and the rest) apply to all our games; each game also gets its own section describing exactly what that game collects and why, since not every game uses the same features. Games not yet released are not covered until they ship.

Umbral Idle: Last Salvage

Sci-fi idle colony builder for Android

Umbral Idle: Last Salvage was developed under the working title "Project ISO," which is why that name may still appear in older store listings or files. The game is available now on Google Play. Where a feature is integrated but not yet switched on, the section below says so.

Advertising

The app uses Unity LevelPlay (ironSource) as its ad mediation platform, with Google AdMob connected as a partner-bidding network. Six rewarded video ad placements exist in the app (Offline 2x, Salvage 2x, Refit Skip, Residuum Bonus, Fleet Charge, and Matter Lump), all entirely optional and only triggered when you tap a button to watch one. The game does not show interstitial or banner ads of any kind.

When you choose to watch a rewarded ad, the ad mediation SDK and the ad networks it works with (including Google) may collect device information and advertising identifiers in order to select and deliver ads, consistent with their own data practices. For details on Google's role as an ad partner, see Google's Privacy Policy.

Account Data & Save Sync

The app offers optional cloud save syncing through Google Play Games Services sign-in, using Unity Gaming Services (Unity Authentication) to link your save to your Google Play Games account. Signing in is optional: you can play entirely offline with a local-only save, and nothing about the game is gated behind signing in.

If you choose to sign in, the app receives a Google Play Games account identifier (via a server auth code, exchanged through Unity Authentication) so it can associate your save data with your account. Your save data (game progress: resources, facilities, tech tree state, and similar in-game values) is then stored with Unity Gaming Services' Cloud Save so it can sync across devices signed into the same Google Play Games account. While signed in, the app also reports achievement unlocks and four leaderboard scores (lifetime Salvage, Iso-Cores, Collapses, and lifetime Insights, all derived from your game progress) to Google Play Games so they appear in your Play Games profile; your display name and avatar on those leaderboards come from Google, not from the app. The app does not receive your Google account email address, contacts, or any other Google account data beyond what Play Games Services provides for sign-in. See Google's Privacy Policy for Play Games Services, and Unity's Privacy Policy for Unity Gaming Services.

Analytics

The app integrates the GameAnalytics SDK to understand how the game is played and balanced. It is switched on only after the consent prompt described below has been answered, and never if you decline. When active, it records anonymous gameplay events (for example: tutorial steps completed, tiers unlocked, Collapses performed, rewarded ads watched, daily rewards claimed, and time away from the game) together with device information such as device model, operating system version, app version, a randomly generated install identifier, and session timings. Events contain in-game numbers only: no name, email address, contacts, precise location, or content you type is ever sent. See GameAnalytics' Privacy Policy.

Crash Reporting

The app uses Unity's built-in engine diagnostics to report crashes and unhandled errors so they can be fixed. A report contains technical information about the failure (stack trace, device model, operating system version, app version, memory state) and no personal information beyond what is needed to identify the device class. See Unity's Privacy Policy.

Notifications

The app can schedule optional local reminders on your device (for example when a Salvage Run has returned, a Derelict Fleet ship has arrived, or the Collapse is at its peak). These are created and stored entirely on your device; no push notification service is used and nothing is sent to us. You can turn them off individually or entirely in Settings, or through the system notification settings.

In-App Purchases

The app offers optional in-app purchases through its in-game Store, processed entirely by Google Play's own billing system: the app itself never receives, processes, or stores your payment card details. Purchases you own are restored automatically from Google Play when you reinstall or change device.

Community Discord

Settings includes a button that opens an invite link to the game's Discord community in your browser or the Discord app. Discord is a separate service with its own privacy practices; see Discord's Privacy Policy. We do not receive anything about your Discord account from this button; it only records, on your device, that you have already claimed the one-time in-game thank-you reward for tapping it.

Reviews & App Updates

The app may occasionally ask whether you would like to rate it, and may prompt you to install a newer version when one is available. Both prompts are shown by Google Play itself, under Google's Privacy Policy; the app is not told whether you left a rating or what you wrote, and no reward is ever tied to leaving one.

Third-Party Services (Umbral Idle: Last Salvage)

Lay the Line: Idle Railway

Idle railway builder for Android

Lay the Line: Idle Railway is a separate, standalone game from Umbral Idle: Last Salvage, sharing only common infrastructure between the two. It does not currently show any advertising and has no leaderboards. Where a feature is integrated but not yet switched on (for example, real in-app products in the store listing), the section below says so.

Account Data & Save Sync

The app offers optional cloud save syncing through Google Play Games Services sign-in, using Unity Gaming Services (Unity Authentication) to link your save to your Google Play Games account, in the same way described for Umbral Idle: Last Salvage above. Signing in is optional: you can play entirely offline with a local-only save.

Analytics

The app integrates the GameAnalytics SDK, on the same terms described for Umbral Idle: Last Salvage above: switched on only after you answer the in-app consent prompt, never if you decline, and recording anonymous gameplay events (for example: track laid, achievements unlocked, milestone ranks reached, works purchased) together with device information and a randomly generated install identifier. No name, email address, contacts, precise location, or typed content is ever sent. See GameAnalytics' Privacy Policy.

Notifications

The app can schedule optional local reminders on your device (for example when a train has arrived). These are created and stored entirely on your device; nothing is sent to us. You can turn them off individually or entirely in Settings.

In-App Purchases

The app may offer optional in-app purchases, processed entirely by Google Play's own billing system on the same terms described for Umbral Idle: Last Salvage above.

Community Discord

Settings includes a button that opens an invite link to the game's Discord community in your browser or the Discord app. Discord is a separate service with its own privacy practices; see Discord's Privacy Policy. We do not receive anything about your Discord account from this button; it only records, on your device, that you have already claimed the one-time in-game thank-you reward for tapping it.

Third-Party Services (Lay the Line: Idle Railway)

Shared Privacy Terms

These sections apply to every game covered by this policy.

Consent

On first launch, each game shows its own plain consent choice (Accept or Decline). Your choice controls whether analytics is switched on at all: if you decline, the analytics SDK is never initialised on your device. Where a game also uses advertising (currently Umbral Idle: Last Salvage only), your choice also controls whether the advertising SDKs may use your data for personalised ads. This dialog is shown to every player in every region: it normally defers to a regional consent form from Google's User Messaging Platform (UMP), which only prompts players in the European Economic Area, the United Kingdom and Switzerland and applies a non-personalised default everywhere else, but that form is not currently available for either game, so each game's own dialog is shown to everyone instead until it is. You can change your choice at any time in Settings, by clearing the app's data, or by contacting us (see Contact below).

Log Data

Using a game, particularly if an error occurs, may involve the third-party SDKs listed above automatically collecting information such as device model, operating system version, app configuration or state, IP address, and timestamps, for diagnostic purposes and to operate their services. Separately, on launch and when returning from the background, each game makes a lightweight request to a Google server purely to read the current time from the response header; this is used to keep offline earnings and daily rewards honest if the device clock has been changed. That request carries no account or game data.

What We Don't Collect

Your Rights & Choices

Depending on where you live, you may have rights under laws such as the EU/UK General Data Protection Regulation (GDPR) or the California Consumer Privacy Act (CCPA), including the right to access, correct, or request deletion of your personal information, object to or restrict certain processing, and withdraw consent where processing is based on consent. To exercise any of these rights, contact us using the details in the Contact section below.

Children's Privacy

We do not knowingly collect personal information from children under the age of 13 in any of our games. If we discover that we have inadvertently collected personal information from a child under 13, we will delete it. If you are a parent or guardian and believe your child has provided us with personal information, please contact us using the details in the Contact section below so it can be addressed.

Data Retention & Account Deletion

Every game covered by this policy always stores your game progress locally on your device first. If you never sign in with Google Play Games, that's the only copy that exists: there is no server-side save data, and uninstalling the app removes your local save data along with it. If you choose to sign in, a synced copy of your save data is also retained in Unity Gaming Services' Cloud Save, tied to your Google Play Games account, for as long as you keep that data synced. You can stop syncing at any time by signing out in Settings, and you can request deletion of your synced save data using the details in the Contact section below.

Security

We use reasonable, commercially acceptable measures to help protect the information described in this policy. However, no method of transmission over the internet, and no method of electronic storage, can be guaranteed to be 100% secure.

Changes to This Privacy Policy

This policy will be revised as features actually ship, and as new games are added. The "Last updated" date at the top of this page reflects the date of the most recent revision.

Terms of Service

Last updated: September 18, 2026

These Terms of Service work alongside the Privacy sections above: those cover what data is collected and why, this section covers the rules for using any Beast of Burden Studios game. "The app" below means whichever Beast of Burden Studios game you are using.

Back to top

License, Not a Sale

Each Beast of Burden Studios game is licensed to you for personal, non-commercial use. It is not sold to you. You may not modify, reverse-engineer, decompile, or redistribute the app or its assets.

Acceptable Use

You agree not to cheat, exploit bugs for unfair advantage, use automation or bots, or attempt to manipulate game data (whether client-side or otherwise) to gain resources you would not otherwise have earned. Violating this may result in your save data being reset, or being reported to the platform (Google Play).

Intellectual Property

Each game's design, code, and original creative content are owned by the developer. Third-party licensed assets (art, fonts, music, and sound effects) are used under their respective licenses; see the in-app Credits screen for the full attribution list rather than a duplicate copy here.

In-App Purchases

All purchases are processed entirely through Google Play's own billing system, subject to Google Play's own Terms of Service in addition to this document, including Google Play's refund policy. Virtual currencies and resources earned or purchased in-game have no real-world monetary value and cannot be exchanged, transferred, or redeemed for cash. Where a game awards items by chance (for example, Umbral Idle: Last Salvage's Recovery Operations can recover crew members), the odds are displayed inside the app wherever such a chance applies, and no real-money purchase directly buys a chance-based item.

Ongoing Updates

Our games continue to receive updates after release: balance, content, and save formats may change between them. We always try to preserve your progress across an update.

Google Play Terms Apply Too

Because our games are distributed through Google Play, using them also means agreeing to Google Play's own Terms of Service, in addition to this document. If the two conflict, Google Play's terms govern platform-level matters (billing and distribution), and this document governs the game itself.

No Warranty

Each app is provided "as is," without guarantees that it will be uninterrupted, error-free, or permanently available.

Limitation of Liability

To the maximum extent permitted by law, the developer is not liable for indirect, incidental, or consequential damages arising from your use of any app. Some jurisdictions do not allow limitations on liability, so this section may not apply to you in full.

Changes to These Terms

This document will be revised as features actually ship and as new games are added. The "Last updated" date above will change whenever this section is revised. Continuing to use an app after a revision means you accept the updated terms.

Termination

Access to an app may be terminated for violating these Terms, including the Acceptable Use section above. You may stop using an app at any time by uninstalling it.

Governing Law

These Terms are governed by the laws of the United Kingdom, without regard to conflict-of-law principles.
