Privacy Policy

Convenience translation: this English version is provided for convenience. If it differs from the French reference version, the French version prevails.

Last updated July 28, 2026

1. Introduction

This Privacy Policy explains how we collect, use, store, and protect your personal data when you use the Skyden application. It applies to every user of the application.

By creating a Skyden account, you acknowledge that you have read this Privacy Policy. The application is published in France by Guillaume Huchet, and we are committed to complying with the EU General Data Protection Regulation (GDPR) and the French Data Protection Act.

2. Data we collect

2.1 Account data

When you register, we collect your email address and pilot name.

2.2 Flight data

We store information that you enter in your digital logbook, including:

  • Departure and arrival dates and times
  • Aircraft used
  • Departure and arrival airports
  • Instructor or co-pilot names
  • Personal notes
  • Digital signatures associated with flights, provided for convenience without legal or certification value

2.3 Usage data

We automatically collect information about how you use the application, including usage events and performance data. This helps us improve the service and user experience and adapt certain interfaces, such as subscription screens, to your usage profile.

2.4 Technical data

We may collect technical information about your device, such as device type, operating system, and unique identifiers required to operate the application.

2.5 Third-party data

You may enter data about other people, such as co-pilots, instructors, or examiners. This data is stored and processed under the same conditions as your other flight data. You are responsible for ensuring that entering it is lawful.

3. Purposes of processing

We process personal data to:

  • Provide your digital logbook, manage subscriptions, synchronize devices, and generate reports and exports
  • Analyze and improve features and performance, diagnose problems, and adapt certain interfaces
  • Contact you about your account or important application updates
  • Meet our legal and regulatory obligations

4.1 Performance of a contract

Processing account and flight data and managing subscriptions are necessary to perform the service contract you accept when using Skyden.

4.2 Legitimate interests

We analyze usage data based on our legitimate interest in improving the service, subject to your rights and freedoms.

We may process or retain data where necessary to comply with legal obligations, including accounting and tax obligations, or to answer a legally valid request from a competent authority.

5. Data sharing and transfers

5.1 No commercial disclosure

We do not sell, rent, or share your personal data with third parties for commercial purposes.

5.2 Processors

We use service providers in these categories:

  • Hosting and synchronization: cloud infrastructure that stores and synchronizes flight data
  • Subscription and payment management: App Store services that process transactions and subscriptions
  • Analytics and product improvement: tools that help us understand usage and improve features
  • User support: tools used to manage support requests

These processors are subject to contractual confidentiality and security obligations consistent with the GDPR.

We may disclose data when required by law or in response to a request from a competent judicial or administrative authority.

5.4 Data location

Your data is mainly stored and processed on servers in the European Union. Where data is transferred outside the EU, we ensure that appropriate GDPR safeguards are in place.

6. Retention

6.1 Active accounts

We retain your data while your account is active so that we can provide the service.

6.2 Inactivity or subscription end

If you stop using Skyden without deleting your account, we retain flight logs for up to 10 years so that you can recover them, based on our legitimate interest in protecting your professional traceability. After prolonged inactivity, we may remind you that the data exists and let you choose whether to retain or delete it.

6.3 Deletion on request

When you delete your account or request erasure, personal data is immediately removed from active systems. Copies in technical backups are removed through normal backup-rotation cycles.

6.4 Automatic deletion

After 10 years without reactivation or instructions from you, residual data is permanently deleted from our servers.

6.5 Billing data

Skyden does not receive or store your bank details because Apple processes payments. We may retain transaction and subscription information supplied by Apple where needed to manage subscriptions and meet accounting and tax obligations for the legally required period.

6.6 Analytics data

Anonymized usage data may be kept longer to improve the service.

7. Data security

We use appropriate technical and organizational safeguards against unauthorized destruction, loss, alteration, disclosure, or access. These include encryption in transit and at rest, secure authentication, regular backups, access controls, and system monitoring. No security system is infallible, so absolute security cannot be guaranteed.

8. Your rights

Under the GDPR, you may have the right to:

  • Access your personal data and information about its processing
  • Correct inaccurate or incomplete data, including directly in the application
  • Request erasure in certain circumstances
  • Receive your data in a structured, machine-readable format such as PDF or CSV/Excel
  • Object to processing based on your particular circumstances
  • Request restriction of processing in certain circumstances

To exercise these rights, contact privacy@skyden.app.

9. Exercising your rights

You may contact privacy@skyden.app or use features available in the application. For security, we may ask you to verify your identity. We aim to respond within one month of receiving a request.

You can export flight data as PDF or CSV/Excel at any time. You can also delete your account and associated data through the application or by contacting us.

10. Cookies and similar technologies

Skyden uses technologies similar to cookies to operate and improve the application. They may remember preferences, keep your session active, and collect anonymized usage statistics. Strictly necessary technologies are enabled by default. Technologies that require consent are enabled only after your choice, which you can later change in the application settings.

11. Changes to this policy

We may change this Privacy Policy. If a change is material, we will notify you in the application or by email. The updated version takes effect when published in the application. We encourage you to review it periodically.

12. Contact and complaints

For questions about this policy or our processing of personal data, contact privacy@skyden.app.

If you believe that processing violates applicable law, you may lodge a complaint with the French data protection authority, the Commission Nationale de l’Informatique et des Libertés (CNIL): www.cnil.fr.

Before litigation, we commit to seeking an amicable solution to disputes concerning personal-data processing.
