Privacy Policy for LocalFlux
Effective date: September 15, 2026
LocalFlux is operated by Fuzzysense. If you have privacy questions about LocalFlux, you can contact us at privacy@localflux.app or visit https://localflux.app.
Overview
LocalFlux is a Windows desktop app for local file conversion. LocalFlux is designed so that your files stay on your device during normal use. The app does not require an account, does not upload your files to Fuzzysense for conversion, and does not send usage analytics or remote crash reports as part of normal app use. If you choose to send feedback, the app sends the message you write and any optional reply email to our support inbox as described below.
Information LocalFlux Does Not Collect or Send
During normal use of the LocalFlux app:
- LocalFlux does not require you to create an account.
- LocalFlux does not upload the files you choose to convert to Fuzzysense.
- LocalFlux does not send usage analytics, advertising identifiers, or remote crash reports to Fuzzysense.
- LocalFlux does not depend on a cloud conversion service to complete its main conversion workflow.
Information Stored Locally on Your Device
LocalFlux may store limited app data locally on your device so the app can work as expected. Depending on how you run the app, this data may be stored in the app’s local storage or under your Windows local app data folder.
This local data can include:
- app settings, such as theme preference, output location preference, and window placement
- local diagnostic records related to conversion failures
- local crash logs created if the app encounters a startup or application error
This information is stored locally for app functionality and troubleshooting. It is not automatically transmitted to Fuzzysense by the app.
Files You Choose to Convert
When you use LocalFlux, the files you select are processed locally on your Windows device using bundled conversion components. Converted files are written to a location you choose or to the default output location selected in the app.
LocalFlux may temporarily read, write, or validate local files as part of the conversion process. These operations happen on your device. Fuzzysense does not receive your source files or converted files through the normal operation of the app.
Optional Feedback
When you select Send feedback in LocalFlux, the app sends the message you wrote and any optional reply email through Cloudflare and AWS Simple Email Service (SES) to the developer’s support inbox at support@localflux.app, hosted by Fastmail. We use this information to review your feedback and, if you leave an email, follow up about it. You can use file conversion without sending feedback or providing an email address.
Feedback does not automatically include your files, conversion history, diagnostic logs, app metadata, or device identifiers. Sending feedback requires an internet connection; file conversion continues to work locally and offline. Unsent drafts remain in memory until the app closes.
Cloudflare processes the network request and uses its source IP address for basic abuse protection. The IP address is not included in the feedback email. AWS SES processes the message for email delivery, and Fastmail processes and stores the resulting email. The feedback service does not log message bodies or keep a separate feedback database. These providers may retain operational metadata under their own policies.
Network Use and External Services
LocalFlux is intended to operate offline for its normal workflow after installation. In normal use, the app does not make network calls for queueing files, choosing formats, or running conversions.
If you choose to open a web link from the app, such as the privacy policy or online user guide link, Windows may launch your web browser and connect to that destination. If you obtain LocalFlux through the Microsoft Store, Microsoft may also process information under its own privacy terms as part of Store installation, licensing, updates, payments, or platform operations. Those activities are governed by Microsoft’s policies, not this Privacy Policy.
Retention and Your Choices
Because LocalFlux stores its app data locally on your device, you generally control that data. You can remove converted files, clear app data, uninstall the app, or delete local settings and log files from your device, subject to normal Windows behavior and any files you choose to keep.
Submitted feedback is retained in our support inbox rather than on your device or in a separate feedback database. Closing or uninstalling the app does not delete a message you have already sent. You can contact privacy@localflux.app to ask about or request deletion of your submitted feedback; include enough information for us to locate the message.
Children’s Privacy
LocalFlux is not directed to children under 13, and Fuzzysense does not knowingly collect personal information from children under 13 through the app.
Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes to LocalFlux, legal requirements, or our business practices. When we do, we will update the effective date above.
