1. Introduction ChopCheck.app (“we,” “our,” or “us”) respects your privacy. This Privacy Policy explains how we collect, use, and protect your data when you use the ChopCheck mobile application (the “App”) and the chopcheck.app website (the “Website”).

2. The ChopCheck Mobile App (Local-First) The ChopCheck App operates on a strict “local-first” basis.

• No Personal Data Collection: We do not collect, store, or transmit any Personally Identifiable Information (PII) such as your name, email address, phone number, or location through the App.

• Local Storage: All app-generated data (practice history, statistics, settings, and streaks) is stored locally on your device’s internal storage.

• No Cloud Sync & No Tracking: We do not operate backend servers for the App, nor do we use third-party analytics (e.g., Google Analytics, Facebook Pixel) or advertising networks within the App. Your workout data never leaves your device unless you manually export it.

• App Permissions:

  • Storage/Files: Requested only if you choose to export (.ccbackup) or import data.

  • Audio/Media: Required for foreground services to play Drone and Metronome sounds efficiently. We do not record audio.

• Backups: If you export your data, you are solely responsible for the security of the backup file once it leaves the App.

3. The ChopCheck Website & Newsletter When you visit our Website, we process minimal data to ensure functionality and communicate with you if requested.

• Language Preference (Cookies): If you change the language setting on our Website, we place a functional cookie on your device. This cookie expires after one year and is used strictly to remember your language preference for future visits. No tracking or marketing cookies are used.

• Newsletter: If you subscribe to our newsletter, we collect your email address. We use a double opt-in process to verify your consent. You can withdraw your consent and unsubscribe at any time using the link provided in every email.

• Security Logs: To protect our Website from malicious activity (e.g., brute-force attacks), our security plugins temporarily log IP addresses. This processing is based on our legitimate interest in maintaining the security of our services.

4. Data Sharing and Processors We do not sell or rent your personal data. We only share data with trusted third-party service providers (Data Processors) necessary to operate our Website:

• Hosting Provider: Our Website is hosted by Site BV (Site.nl), located in the Netherlands. They process website traffic data on our behalf.

5. Data Retention

• App Data: Retained on your device until you uninstall the App or clear its data.

• Newsletter Data: Retained until you unsubscribe, after which your email address is securely deleted.

• Security Logs: IP logs are kept only as long as necessary to ensure website security and are routinely cleared.

6. Your GDPR Rights Under the General Data Protection Regulation (GDPR), you have the right to:

• Access the personal data we hold about you (e.g., your newsletter subscription).

• Rectify inaccurate or incomplete data.

• Erase your personal data (“right to be forgotten”).

• Restrict or Object to the processing of your data.

• Data Portability (receive your data in a structured, commonly used format).

• Lodge a complaint with your local data protection supervisory authority.

To exercise these rights regarding your Website or Newsletter data, contact us using the details below. (Note: Because we do not collect data via the App, we cannot access, delete, or provide app data to you; you must manage this directly on your device).

7. Children’s Privacy ChopCheck does not knowingly collect data from children. Our App collects zero personal data, making it safe for users of all ages.
