2. Overview

Coder's Friend is designed with your privacy in mind. The app operates entirely on your device and does not collect, store, or transmit any personal data.

3. Data Collection

Coder's Friend does not collect any personal data. Specifically:

• No personal information is collected or processed
• No usage analytics or tracking
• No cookies or device identifiers
• No network requests are made by the app
• No data is transmitted to us or any third party

4. Data Storage

All data (such as calculation history and settings) is stored exclusively on your device. Nothing leaves your device.

5. Legal Basis (Art. 6 GDPR / DSGVO)

Since the app does not process any personal data, no legal basis for data processing is required. Should this change in the future, the applicable legal basis will be stated here.

6. Third-Party Services

Coder's Friend does not integrate any third-party analytics, advertising, crash reporting, or tracking services.

7. Website Hosting

This website is hosted on a self-managed server. When you visit this website, your browser transmits certain data for technical reasons (e.g., IP address, browser type, access time). Server log files may be temporarily stored for security and maintenance purposes. This processing is based on Art. 6(1)(f) GDPR (legitimate interest in the secure operation of the website). Log data is not combined with other data sources and is deleted regularly.

8. Your Rights (GDPR / DSGVO)

Under the General Data Protection Regulation, you have the following rights:

• Right of access (Art. 15 GDPR) — request information about any data we process
• Right to rectification (Art. 16 GDPR) — request correction of inaccurate data
• Right to erasure (Art. 17 GDPR) — request deletion of your data
• Right to restriction of processing (Art. 18 GDPR)
• Right to data portability (Art. 20 GDPR)
• Right to object (Art. 21 GDPR)

Since we do not collect personal data through the app, these rights primarily apply to any data processed through this website (server logs).

9. Right to Lodge a Complaint

You have the right to lodge a complaint with a data protection supervisory authority (Art. 77 GDPR). The competent authority for Baden-Württemberg is:

Der Landesbeauftragte für den Datenschutz und die Informationsfreiheit Baden-Württemberg

10. Children's Privacy

The app does not collect any data from anyone, including children under the age of 16 (Art. 8 GDPR).
