Privacy
Your PowerPoint file stays on your device.
PPTX Theme Editor is a browser-based utility. It reads, edits, and exports your PPTX file locally in the browser. The tool does not upload your presentation to a server for processing.
File handling
When you choose a PPTX file, your browser gives the page access to that file for the current session. The editor unzips and modifies the file in browser memory, then creates a downloadable PPTX when you export.
- Your presentation is not uploaded by the editor.
- Your presentation is not stored by the editor.
- Your presentation is not shared with the project owner.
- Refreshing or closing the page clears the in-memory editing session.
Third-party links
The site links to external services for feedback and optional coffee support. Those links are separate websites with their own privacy practices. Do not include confidential presentation content in feedback forms.
Browser and hosting basics
Like most static websites, the hosting provider may receive ordinary request information when you load the page, such as IP address, browser type, requested URL, and timestamp. That hosting request does not include the PPTX file you open locally in the editor.
Analytics
The site uses Umami Cloud for privacy-friendly aggregate analytics. Umami does not use cookies on this site. It records pageviews and a small number of product events, such as opening a file, applying a brand kit, or exporting a deck, so the project owner can understand whether the tool is useful.
Analytics events do not include your presentation, file name, file size, colors, XML content, or any deck contents.
Use the editor without uploading a deck.
Open a PPTX file, make color edits in your browser, and download the updated file when you are done.
