Local-first app data
Party data, box data, encounter logs, death history, notes, settings, and other run information are stored locally on your device.
Privacy Policy
Your run stays with you.
LockeBox is a local-first emulator and tracker. The app does not require accounts, does not serve ads, and does not send your run history to Heavy C servers.
This policy covers the LockeBox app, the LockeBox website pages under /lockebox/, and the download and distribution flow. Last updated: July 9, 2026.
Short Version
LockeBox is designed to avoid collecting your personal run data.
If you use the app without emailing us or using a third-party distribution service, your emulator data, save-aware tracker data, and imported files stay on your device.
No required account
LockeBox does not require account creation, cloud login, or a hosted profile to use the app.
No in-app ads or telemetry
LockeBox does not include ad networks, behavioral tracking, or analytics SDKs that report your gameplay back to us.
What LockeBox Handles
Files you provide are used to run and track your game locally.
Run and emulator data
- Game settings, save states, and app preferences.
- Run details such as team, box, routes, deaths, badges, and level caps.
- Imported saves and related metadata needed to keep the tracker in sync with your run.
User-supplied game files
- ROMs, BIOS files, and save files are supplied by you.
- LockeBox does not distribute those files.
- Those files are used locally by the app and are not uploaded to Heavy C servers by default.
What We Do Not Collect
The app is not built around user profiling.
Not part of the current app
- No required sign-in or account registration.
- No in-app advertising identifiers.
- No sale of personal data.
- No gameplay analytics dashboards tied to your identity.
Website and download context
The LockeBox app itself is separate from the services used to host pages and distribute builds. If you visit the website, download a build from GitHub Releases, install from the Google Play Store, or join TestFlight, those providers may process standard request, device, or account information under their own policies.
Contact and Support
Email is optional and only used when you choose to contact us.
If you email us
If you contact Heavy C Development Studio at [email protected], we receive your email address and any information you include in your message or attachments. We use that information to respond to you, review bug reports, and support the project.
Please avoid sending sensitive files
Do not send ROMs, BIOS files, or other copyrighted game files. If you report a bug, send only the minimum information needed to explain the issue.
LockeBox is actively maintained. If a future build introduces cloud sync, accounts, or new data flows, this page will be updated before or when those features ship.
