  • Legitimate interest: analytics, security, and service improvement
  • Consent: optional features like marketing communications

5. Third-Party Services

We use the following third-party services to operate Lucend:

  • Hetzner (Germany/Finland/USA) — infrastructure hosting

Each provider processes data under their own privacy policy and in accordance with applicable data protection agreements (DPAs).

6. International Data Transfers

For users in the EU, your data is primarily processed within the EU (Hetzner Germany/Finland, GCP EU regions). Some services (Cloudflare, RevenueCat, Expo) may process data in the USA under the EU-U.S. Data Privacy Framework or Standard Contractual Clauses.

For users in the US, your data is processed on US-based infrastructure (Hetzner US, GCP US regions).

7. Data Retention

We retain your data for as long as your account is active. Upon account deletion, your personal data is permanently removed within 30 days, except where retention is required by law.

8. Cookies & Analytics

Our website uses privacy-friendly analytics that do not require cookies or personal data collection. We may in the future use tracking pixels (e.g., Meta, TikTok) for marketing measurement — if so, these will only be activated with your explicit consent.

9. Your Rights

Under GDPR, you have the right to:

  • Access the personal data we hold about you
  • Rectify inaccurate data
  • Request deletion of your data
  • Restrict or object to processing
  • Data portability

10. Security

We implement industry-standard security measures including encryption in transit (TLS), encrypted storage, VPC isolation, and access controls. While no system is 100% secure, we take reasonable steps to protect your data.

11. Changes to This Policy

We may update this policy from time to time. Significant changes will be communicated via email or in-app notification. Continued use of the service after changes constitutes acceptance.
