DocScrub Chrome extension privacy policy

DocScrub cleans PDFs on your device. Your PDF files, filenames, document metadata and cleaned copies stay in Chrome unless you choose to share them. Version 1.1.0 adds optional paid Batch Cleanup and uses an online license check for paid access.

Scope and publisher

This policy covers “DocScrub - PDF Metadata Sanitizer,” Chrome extension ID oecjmchkamednhfolmdlbjfjhmkgkjke, published by Rare Frequency Works. Versions 1.0.1 and 1.1.0 process PDFs locally. The earlier 1.0.0 package used a server-upload design. The DOCSCRUB website, API and other apps have their own privacy notices.

PDF cleanup

When you choose a file, the extension reads it on your device. It uses the filename to show your selection and name the download. Single-PDF cleanup is free. Batch Cleanup can process multiple selected PDFs and package cleaned copies in a ZIP. The bundled PDF library removes PDF Info and XMP metadata. Cleanup leaves visible text, comments and attachments in place and does not guarantee anonymity.

Files are held in temporary browser memory during processing. The extension does not intentionally retain a document or metadata history. Chrome and your operating system manage memory, downloads and temporary storage. Your downloaded copies and Chrome’s download records remain under your control.

Paid access and recovery codes

For paid Batch Cleanup, DocScrub generates a private recovery code. Chrome stores the code and a signed access record in the extension’s local storage. The extension sends the code over HTTPS to our Cloudflare-hosted licensing service when opening checkout, checking access or restoring a purchase. An active DOCSCRUB Web Premium subscription can also unlock Batch Cleanup in Chrome using its recovery code.

The licensing database keeps a hash of the code and records needed to verify or restore access, including purchase and entitlement status and Stripe identifiers associated with the purchase. The service uses this information to manage paid access and respond to payment changes such as refunds. Our hosting provider also receives connection information such as IP address for serving requests and limiting abuse. Keep your recovery code private. Clearing local storage or uninstalling the extension can remove the saved code from that browser.

Checkout and payment information

The purchase button opens a Stripe-hosted checkout. Stripe Managed Payments, through Link, handles the payment and any billing or contact details you provide at checkout. The extension and DocScrub licensing database do not receive or store your card number. Stripe shares payment identifiers and status with Rare Frequency Works so the licensing service can grant and verify access. See Stripe’s privacy policy for how Stripe handles checkout data.

Browser access, sharing and advertising

Version 1.1.0 requests access to the DOCSCRUB licensing service for purchase and access checks. The extension has no content scripts and does not read your browsing history, website content or files you have not selected. It has no advertising, analytics SDK or session recording. Rare Frequency Works does not sell extension data, use it for advertising, or send your documents to AI services.

Opening an external link takes you to a separate website. Hosting and security providers can receive ordinary web request information. This policy page contains no analytics or advertising scripts. See the Rare Frequency Works website privacy policy for other pages on this site.
