Privacy policy
CPU Bloom processes system readings on your computer. It does not send those readings to the developer.
What the app reads
CPU Bloom reads processor information, CPU utilization, physical-core and thread counts, RAM usage, and supported GPU activity to draw its visualizations. On Windows it uses local Windows interfaces and libraries. In the portable edition, an optional NVIDIA fallback uses the locally installed nvidia-smi utility and may also read GPU temperature and memory. Readings depend on the operating system, hardware and drivers.
The app processes these readings in memory on your device. It does not upload hardware identifiers, readings or usage history. CPU Bloom does not access your contacts, location, camera, microphone or browsing history as part of its functionality.
Files kept on your computer
- Preferences: theme, window size and other app settings are saved in your Windows user profile. The MSIX edition uses package-local application data; the portable edition uses
%APPDATA%\CPU Bloom. - Animation cache: locally generated image files speed up animation loading. They contain animation pixels, not personal documents. The disk cache is trimmed to a 256 MiB budget.
- Screenshots: pressing S saves the app view to Pictures → CPU Bloom, using your configured Windows Pictures location. Screenshots can show hardware details and readings. They are not automatically uploaded by the app. If your Pictures folder is synced by OneDrive or another service, that service may sync them according to your settings.
- Preference import and export: these are optional file operations you initiate. An import copies supported display preferences; it does not inherit startup consent or delete the portable installation.
Local settings and files are protected by your operating system's user-account and filesystem controls. CPU Bloom does not add its own file encryption. Preferences remain until changed or removed; cached images may be regenerated. Exported screenshots and preference backups remain wherever you save them until you delete them.
Starting with Windows
Start with Windows is optional and off by default for a new installation. The MSIX edition uses a Windows startup task; the portable edition uses a shortcut in your personal Startup folder. You can change this preference in the app. The MSIX edition respects Windows Settings and organization policy controls.
Sharing and third-party services
The app does not send its system readings or preferences to the publisher or third parties. If you choose to share a screenshot, backup or support message, that is a separate action under your control.
Microsoft Store and Windows may process installation, purchase, update or diagnostic information under the Microsoft Privacy Statement. That processing is separate from CPU Bloom's local operation.
This website and support enquiries
These pages are hosted by GitHub Pages. They contain no analytics scripts, advertising or contact forms. GitHub may process connection information, including IP addresses and request logs, to serve and secure the site under its privacy statement.
If you email the developer, your email address and message are received through Gmail and used to respond, troubleshoot the issue and maintain a support record. If you open a GitHub issue, your account name and issue content are public and handled under GitHub's policies. Please do not post private information, passwords or access tokens in public issues.
Support correspondence is kept while needed to address and follow up on your request, then deleted when no longer needed, subject to applicable legal obligations. You can ask for access, correction or deletion of correspondence held by the developer by emailing the address below. GitHub controls account and platform records; public copies made by others may remain outside the developer's control.
Removing your data
The publisher has no copy of your app readings or local preferences to delete. You control them on your device. Windows manages removal of MSIX application data during uninstall; Windows backup or restore settings may affect what is retained. Exported screenshots, backup ZIPs and a separate portable installation are not removed with the Store app. See Support for help locating local data.
Changes and contact
This page will be updated if CPU Bloom's data practices change, with a new effective date. For privacy questions or requests, contact David Carr, publisher David-Carr, at daggysheep@gmail.com.
