Welcome to Book Studio: KDP & eBook, provided by Geo Astro (collectively, "we", "us", or "our"). This Privacy Policy describes how we collect, use, process, and protect your personal data when you use our mobile application and related services (collectively, the "Services"). Please review this document carefully to understand our privacy practices.
1. What Data Do We Collect?
We collect information in three basic categories:
(a) Information You Voluntarily Provide to Us:
- User-Generated Content & Projects: When you design books, create covers, arrange manuscript pages, add headings, and organize text inside the studio, this content is processed to build your book projects.
- Uploaded Images & Assets: When you import images, graphics, illustrations, or cover artworks from your device into the app, these files are processed to render your pages and export covers.
- Contact Information: If you reach out to our service support or submit feedback, we record your email address and message contents to assist you and resolve your inquiries.
(b) Information Processed Locally on Your Device:
Book Studio: KDP & eBook is designed as an on-device creative workspace. Your project drafts, layouts, and exported files (such as PDF cover/interior files and EPUB files) are generated and stored locally on your device storage unless you choose to export or share them manually.
(c) Information Collected Automatically:
- Device Data: We may collect generic information about your device, such as device model, platform, network type, operating system version, screen resolution, language settings, Android ID, and advertising identifiers (such as GAID for Android devices).
- Usage & Diagnostic Data: Technical logs, crash reports, and performance indicators used to analyze app stability and resolve bugs.
2. How Do We Use Your Data?
We use the collected information for legitimate operational and technical purposes:
- To fulfill your requests for book design tools, page layout editing, cover preparation, and file generation (PDF and EPUB).
- To provide technical assistance, troubleshooting, customer support, and solicit product feedback.
- To enhance the stability, security, and performance of our application.
- To comply with legal obligations and enforce our terms.
3. Security of Your Data
We attach great importance to the security of your data and adopt industry-standard security practices to prevent unauthorized access, alteration, disclosure, or destruction. We employ administrative, technical, and physical security controls where appropriate.
If any data security incident occurs, we will notify affected users and supervisory authorities as required by applicable laws via appropriate notices or email.
4. How We Store and Retain Your Data
Because your manuscripts, graphics, and book projects remain locally on your personal device, you maintain direct control over your project assets. Removing the app or clearing app storage will delete locally saved work unless you have exported it.
Any technical data or support emails retained by us are held only for the minimum period necessary to fulfill customer support and legal obligations, after which they are deleted or anonymized.
5. How We Share Your Personal Data
We do not sell, rent, or trade your personal data. We only share information under the following limited conditions:
- With Your Consent: We share data with third parties when you explicitly grant us permission to do so.
- Service & SDK Providers: We integrate reliable software development kits (SDKs) to improve application performance (e.g., Firebase analytics and Google Play Services).
- Advertising Partners: We may share non-personally identifiable identifiers (such as GAID) with ad partners to display relevant advertisements. You can opt out of interest-based ads via your Android system settings (Settings > Google > Ads).
- Pursuant to Law: We may disclose data if required by legal summons, court procedures, or regulatory authorities.
6. How We Process Children’s Data & Age Compliance
Our Services are directed to authors, self-publishers, educators, and creative adults. We do not knowingly collect personal data from children under the age of 16 (or the relevant age threshold in your jurisdiction).
Age Compliance Using Play Age Signals API:
To comply with child protection laws (such as COPPA and Google Play Families Policies), our application utilizes the Play Age Signals API provided by Google Play. This API delivers a verification signal regarding user supervision or consent status directly from Google Play. We do not collect or store your date of birth or actual age via this API. The signal is strictly used to verify age requirements and restrict features where parental approval is required.
7. What Are Your Rights and Choices?
You have full control over your personal data, including the right to:
- Access & Correction: Access the personal information we hold about you or request corrections to inaccurate details.
- Withdraw Consent: Revoke any previously granted permissions at any time via your device settings.
- Deletion (Right to be Forgotten): Request the permanent erasure of your personal data held in our support records.
- Restriction & Objection: Object to or request the limitation of our data processing under specific legal grounds.
8. Cross-Border Data Transfers
If any data is processed outside your home country, we ensure that appropriate safeguards (such as Standard Contractual Clauses approved by the European Commission) are in place to preserve your privacy rights under international standards.
9. Additional Notice for California Residents (CCPA)
Under the California Consumer Privacy Act (CCPA), California residents have specific rights regarding their personal information:
- The right to know what personal identifiers and categories of data we collect and disclose.
- The right to request deletion of personal information.
- The right to equal service and non-discrimination when exercising privacy rights.
- We do not sell your personal information.
10. Additional Notice for EU/EEA Residents (GDPR)
In accordance with the General Data Protection Regulation (GDPR), we process your data under legitimate legal bases: contract performance (Article 6(1)(b)), legitimate interests (Article 6(1)(f)), and compliance with legal obligations (Article 6(1)(c)). You have the right to lodge a complaint with your local Data Protection Authority if you believe our data processing violates applicable rules.
11. Additional Notice for Brazilian Residents (LGPD)
In compliance with the Lei Geral de Proteção de Dados (LGPD), Brazilian residents have the right to confirm processing, access data, correct incomplete or outdated information, request anonymization or deletion, and revoke consent at any time.
