Plain-language summary: KDP Launch Check is designed to process your book information and PDF checks locally in your browser. We do not sell your information, use it for advertising, or transmit your book content to our servers.
1. About this policy
This Privacy Policy applies to the KDP Launch Check Chrome extension (“KDP Launch Check,” “the extension,” “we,” “us,” or “our”). KDP Launch Check helps self-publishers review metadata, calculate cover and print dimensions, estimate royalties, inspect basic PDF properties, manage saved projects, and complete publishing-readiness checklists.
2. Information you enter
The extension may process information that you voluntarily enter, including:
- Book titles, subtitles, author names, descriptions, and keyword phrases
- Trim size, page count, paper type, bleed, pricing, printing-cost, and sales estimates
- Checklist progress and project names
- Saved project settings and preferences
This information is used only to provide the extension’s features.
3. Local browser storage
KDP Launch Check uses Chrome’s storage capability to save drafts, preferences, checklist progress, and projects in your browser profile.
We do not operate a cloud account system for this extension, and we do not receive or store your saved project data on our servers.
4. PDF file processing
When you choose a PDF for inspection, the extension processes the file locally in your browser to perform basic checks such as page count, page dimensions, consistency, spread detection, and compatibility warnings.
Your PDF file and its contents are not uploaded to us.
5. Website and browsing activity
KDP Launch Check does not request broad website access and does not read your browsing history, webpage content, passwords, payment details, or activity on unrelated websites.
6. Analytics, advertising, and tracking
The extension does not include third-party advertising, behavioral analytics, cross-site tracking, or advertising identifiers.
7. Selling or sharing information
We do not sell, rent, license, or trade your personal information or book-project data. We do not share extension data with advertisers or data brokers.
8. Optional donations
KDP Launch Check may include an optional donation button or QR code that opens PayPal. Donations are voluntary and do not unlock additional features.
PayPal is a separate third-party service. When you choose to open PayPal, your interaction with PayPal is governed by PayPal’s own privacy policy and terms. KDP Launch Check does not receive your PayPal password or full payment information.
9. Data retention and deletion
Locally stored extension data remains in your browser profile until you delete it. You can remove stored data by:
- Deleting individual saved projects inside the extension
- Using the extension’s reset or clear-data option, when available
- Clearing extension data through Chrome
- Uninstalling KDP Launch Check
10. Data security
We limit the extension’s requested permissions and design its core processing to happen locally. However, no browser, device, or storage method can be guaranteed to be completely secure. You are responsible for maintaining the security of your device and Chrome profile.
11. Children’s privacy
KDP Launch Check is intended for adult publishers and is not directed to children under 13. We do not knowingly collect personal information from children.
12. Amazon and KDP disclaimer
KDP Launch Check is an independent tool and is not affiliated with, endorsed by, sponsored by, or operated by Amazon.com, Inc. or Kindle Direct Publishing. “Amazon,” “Kindle,” and “KDP” are trademarks of their respective owner.
13. Changes to this policy
We may update this Privacy Policy when the extension changes, legal requirements change, or clarification is needed. The effective date at the top of this page will be updated whenever material revisions are made.
