Privacy Policy

Summary

FileJuice's privacy policy is very simple: we do not collect or store any data on you at all. We don't use cookies or trackers, analytics are completely private, and all conversions (except videos) happen locally on your browser. Videos are deleted after being downloaded, or within an hour. We use Plausible for completely anonymous and aggregated analytics, and Stripe for donations.

Note this may only apply to the official FileJuice instance; third-party instances may handle your data differently.

Conversions

Most conversions (images, documents, audio) happen entirely locally on your device using WebAssembly. Your files never leave your device.

Video conversions are performed on servers as they require more processing power. Videos are deleted after download or within one hour, unless you explicitly give permission for troubleshooting.

Conversion Errors

When a video conversion fails, we may collect some anonymous data to help us diagnose the issue. This data may include:
  • The job ID, which is the anonymized file name
  • The format you converted from
  • The format you converted to
  • The FFmpeg stderr output of your job (error message)
  • The actual video file (if given explicit permission)
This information is used solely for the purpose of diagnosing conversion issues. The actual video file will only ever be collected if you give us permission to do so, where it will only be used for troubleshooting.

Analytics

We self-host a Plausible instance for completely anonymous and aggregated analytics. Plausible does not use cookies and complies with all major privacy regulations (GDPR/CCPA/PECR). You can opt out of analytics in the "Privacy & data" section in settings and read more about Plausible's privacy practices here.

Local Storage

We use your browser's local storage to save your settings, and your browser's session storage to temporarily store the GitHub contributors list for the "About" section to reduce repeated GitHub API requests. No personal data is stored or transmitted.

The WebAssembly versions of the conversion tools we use (FFmpeg, ImageMagick, Pandoc) are also stored locally on your browser when you first visit the website, so you don't need to redownload them each visit. No personal data is stored or transmitted. You may view or delete this data at any time in the "Privacy & data" section in settings.

Contact

For questions, email us at: hello@filejuice.app. If you are using a third-party instance of FileJuice, please contact the operator of that instance instead.
