Privacy Policy
bunbunpdf is built around local browser-based PDF editing. This policy explains what the site processes, what stays on your device, and how third-party services may use data when you use the site.
Last updated: June 4, 2026
PDF files and document content
PDF editing runs in your browser with JavaScript and WebAssembly. PDF files, document text, filenames, form values, signatures, initials, dates, annotations, and user-entered content are not uploaded to bunbunpdf servers for editing.
Exports are generated in your browser and downloaded by your browser. If you choose to send an exported PDF somewhere else after downloading it, that transfer is outside bunbunpdf.
Browser storage
The app may use browser storage such as localStorage and IndexedDB to keep editor preferences, signing profiles, tool defaults, and temporary editing state on your device. You can clear this data through your browser settings.
Product analytics
bunbunpdf collects limited aggregate product analytics for events such as PDFs opened, imported, edited, exported, and printed. These events use coarse buckets such as page count, file size, edit category, export type, and exported file count.
Product analytics do not include PDF files, document text, filenames, form values, signatures, initials, dates, annotation notes, or other user-entered PDF content.
Google services and advertising
bunbunpdf uses Google measurement services and may use Google AdSense or other Google advertising services. Google and its partners may use cookies, local storage, web beacons, IP addresses, device information, browser information, page URLs, referrers, and interaction data to serve, personalize, limit, and measure ads.
Third-party vendors, including Google, may use cookies to serve ads based on prior visits to this site or other sites. You can control personalized advertising through Google Ad Settings at https://adssettings.google.com/ and learn more about Google advertising technologies at https://policies.google.com/technologies/ads
Users in regions that require consent for advertising cookies or personalized ads may be shown a consent prompt before those services are used.
Contact email
If you contact bunbunpdf by email, the information you send is used to respond to your message, investigate issues, and improve the service. Do not email sensitive PDF files unless you intentionally want to share them with us.
Changes
This policy may be updated as the product, analytics, or advertising setup changes. The updated page will be posted here.
