Privacy Policy

1. Introduction

Welcome to KindNudge. We respect your privacy and are committed to protecting your personal data and relationship metadata. This privacy policy will inform you about how we look after your personal data when you visit our website or use our application.

2. Data We Collect

We may collect, use, store and transfer different kinds of personal data about you and your partner, which we have grouped together as follows:

  • Identity Data: Name, Email address.
  • Biological & Timing Data: Cycle lengths, period dates, and special relationship dates needed for timing-based nudges.
  • Preferences Data: Relationship vibes, partner interests, and customized system preferences for AI interaction.
  • Transaction Data: Subscription tiers and status. We use secure third-party payment providers and do not store raw credit card information.

3. How We Use Your Data

We will only use your personal data when the law allows us to. Most commonly, we will use your personal data in the following circumstances:

  • To provide deterministic biological mapping and AI-generated suggestions context-aware to your relationship.
  • To manage your account, subscription, and payments.
  • To send magic links for passwordless, secure authentication.
  • To notify you through push notifications (if enabled).

4. AI Data Processing

To generate customized nudges, certain preferences and cycle phases are processed through OpenAI models. We only transmit the strict minimum context required. We do NOT sell your data to data brokers, nor do we allow your personal relationship metrics to be utilized for public LLM training.

5. Data Security

We have put in place appropriate security measures to prevent your personal data from being accidentally lost, used or accessed in an unauthorized way, altered, or disclosed. Access to your personal data is limited to those employees, agents, and third parties who have a business need to know.

6. Your Legal Rights

Under certain circumstances, you have rights under data protection laws in relation to your personal data. This includes the right to request access, correction, erasure, or restriction of processing of your personal data. You can delete your account natively within the application settings which instantly nullifies all recorded metrics.
