FAQ

Does this work with all versions of Prism?

refractions supports Prism 9 and later (modern .pzfx format). Prism 8 support is best-effort — older .pzf files may need to be re-saved as .pzfx first.

Do my colleagues on Windows need refractions?

No. refractions keeps the PPTX as a real OLE-embedded Prism file. Colleagues on Windows can double-click any chart to open it in Prism and edit, exactly like before.

What happens if I get a new Mac?

If you've used all your license seats, email [email protected] with the license key and the hostname of the Mac you want to deactivate. We'll free a seat within one business day.

Is my PPTX data sent to the cloud?

No. All processing happens locally on your Mac. The only network call refractions makes is a license validation check against https://refractions.app/api/validate-license/, which sends only:

  • The license key
  • A SHA-256 fingerprint of your hostname and primary MAC address

No PPTX content, no chart data, no personally identifying information.

What's the refund policy?

If refractions doesn't work for you, email support within 30 days for a full refund.

Can I install refractions on multiple Macs with one license?

The Individual tier covers 1 Mac. The Lab tier covers 5 Macs. Need more? Email support about volume licensing.

Does refractions work without an internet connection?

Yes — for up to 7 days after the last successful license validation. You only need internet access for activation and the periodic re-validation.

How do I uninstall?

Run ~/.refractions/uninstall.sh. This removes the daemon, the LaunchAgent, and the task pane manifest from PowerPoint. Your PowerPoint files are not modified.
