Data We Collect

We collect information in the following categories:

Account Information

  • Email address (required to create an account and receive your orders)
  • Name (optional, used for order fulfillment and personalization)
  • Password (stored as a hashed value — we never see your plaintext password)

Uploaded Photos

  • Photos you upload for coloring page generation
  • These are processed by our AI and stored temporarily to generate your output
  • Photos may contain biometric data (faces) — we use this solely for the coloring page transformation and do not build face recognition databases

Payment Information

  • We collect billing name and email for payment processing
  • Credit card numbers and full payment details are handled directly by our payment processor — we do not store raw card data on our servers

Order & Delivery Information

  • Shipping address for physical book orders
  • Order history and transaction records

Usage Data

  • Pages visited and features used
  • Device type, browser, and IP address
  • Conversion events (e.g., uploads, downloads, purchases)
  • Error logs for debugging and service improvement

How We Use Your Data

We use your information for the following purposes:

  • Coloring page generation: Your uploaded photos are sent to our AI processing pipeline to create line-art coloring pages. This is the core service.
  • Order fulfillment: Shipping address and order details are passed to our print fulfillment partner (Lulu) to produce and ship your physical books.
  • Account management: Email and account data are used to authenticate you, send order confirmations, and provide customer support.
  • Payment processing: Billing information is used to charge for purchases and manage subscriptions.
  • Service improvement: Aggregated usage data helps us improve AI output quality and the overall product experience.
  • Marketing (opt-in only): If you opt in, we may send product updates, promotions, and tips. You can unsubscribe at any time via any email we send.
  • Legal compliance: We may process data to comply with applicable laws, respond to legal requests, and enforce our Terms of Service.

We do not use your photos to train AI models, and the AI services that process them do not use your photos for training under the paid API terms that govern our use of those services.

Right to Delete

You have the right to request deletion of personal information we have collected from you, subject to certain exceptions (e.g., completing transactions, legal obligations).

Right to Opt-Out of Sale

We do not sell your personal information as defined by the CCPA. You therefore do not need to opt out of a sale. We do not have a "Do Not Sell My Personal Information" link because there is nothing to opt out of.

We will not discriminate against you for exercising any of your CCPA rights. Exercising these rights will not result in different pricing, service quality, or access to features.

Children's Privacy (COPPA)

BLNKBooks is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13.

If you are a parent or guardian and believe your child under 13 has provided us with personal information, please contact us at privacy@blnkbooks.com and we will delete that information promptly.

If you upload photos of minors for coloring page generation, you represent that you have the legal right to do so (as a parent, legal guardian, or authorized representative) and that such use is appropriate. See our Terms of Service — Likeness & Consent section for full requirements.

We take reasonable technical and organizational measures to protect your personal data from unauthorized access, disclosure, alteration, or destruction. These include:

  • Encrypted data transmission (HTTPS/TLS)
  • Encrypted storage of sensitive credentials
  • Access controls limiting who can access production systems
  • Regular security reviews

No method of transmission over the internet is 100% secure. While we work hard to protect your data, we cannot guarantee absolute security. In the event of a data breach that affects your rights, we will notify you in accordance with applicable law.

11

Policy Changes

We may update this Privacy Policy from time to time. When we make material changes, we will update the "Last Updated" date at the top of this page and, where appropriate, notify you by email or a notice on our website.

Your continued use of BLNKBooks after any change constitutes acceptance of the updated policy. If you do not agree to the changes, please stop using the service and contact us to request account deletion.
