Privacy Policy
Last updated August 2026
This explains what information KDP Workspace collects, why, and how it's handled.
What we collect
If you use the free tool without an account, your data (books, checklists, settings) stays in your own browser and never reaches our servers.
If you sign up for KDP Workspace Pro or Pro+, we collect:
- Your email address and a securely hashed password, to create and secure your account
- The book, library, and settings data you enter into the tool, so it can sync across your devices
- Basic subscription and billing status (whether your subscription is active), provided to us by Stripe
If you use Pro+ and upload your own KDP sales reports or Amazon Ads reports, we store that data too, so the analysis features (net profit, true profit, portfolio view, and similar) can work. This is genuinely sensitive business data, your real revenue and ad spend, and it's used only to power the features you're using it for. We don't analyze it in aggregate, sell insights derived from it, or share it with anyone else.
We don't collect or store your full payment card details. Those go directly to Stripe, our payment processor.
How we use it
We use this information to provide the service: keeping you signed in, syncing your data across devices, and confirming your subscription is active so you can use paid features. We don't sell your data or use it for advertising.
Analytics
We use two tools to understand how the site is used generally, separate from your account data within the app itself:
- Google Analytics, which uses cookies to track page views and general visitor behavior.
- Cloudflare Web Analytics, a privacy-focused option that doesn't use cookies or track individuals across sites.
Who we share it with
- Stripe, to process subscription payments
- Cloudflare, our hosting and infrastructure provider, which stores your account and synced book data, and also provides our privacy-focused analytics
- Google Analytics, for general site traffic analytics
We don't share your data with anyone else, except where required by law.
How long we keep it
We keep your account and synced data for as long as your account exists. If you'd like your account and data deleted, contact us at the address below.
Security
Data is transmitted over HTTPS and stored with industry-standard practices. No system is perfectly secure, but we take reasonable steps to protect your information.
Children's privacy
KDP Workspace isn't directed at children under 13, and we don't knowingly collect information from them.
Changes to this policy
If we make material changes to this policy, we'll update the date at the top of this page.
