4. Legal Basis for Processing
Where the General Data Protection Regulation (GDPR) or similar law applies, we process your data on the following legal bases: performance of a contract (to provide the Service you signed up for), legitimate interest (to secure and improve the Service), legal obligation (for example, tax and accounting records), and consent (where applicable, such as optional marketing communications).
5. Third Parties We Share Data With
We share the minimum data necessary with the following categories of service providers, each acting under their own privacy terms:

We may also disclose data if required by law, legal process, or to protect the rights, safety, or property of NicheQuill, our users, or the public.
6. International Data Transfers
Some of the providers listed above may process data outside your country of residence, including in the United States. Where required, we rely on appropriate safeguards recognized under applicable data protection law (such as Standard Contractual Clauses) to protect data transferred internationally.
7. Data Retention
We retain your account and project data for as long as your account is active. If you request account deletion, we will delete your personal data and project content within a reasonable time, except where we are legally required to retain certain records (such as payment records, for accounting and tax purposes).
8. Data Security
We apply reasonable technical and organizational measures to protect your data, including password hashing, encrypted connections (HTTPS), and access controls on our infrastructure. No method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

11. AI Processing of Your Content
To generate your books, covers, and metadata, the text and prompts you provide (topic, genre, audience, and similar project details) are sent to our AI provider, OpenAI, for processing.
