2. Data Collection

Website

Our website is hosted on AWS S3 in Frankfurt, Germany (eu-central-1) and distributed via CloudFront. We collect minimal website analytics data:

  • Plausible Analytics - Privacy-focused web analytics (no cookies, no personal data collection)
  • No tracking cookies
  • No user behavior tracking beyond basic page views
  • No server logs with personal data

Analytics Details: We use Plausible Analytics, a privacy-focused analytics service that does not use cookies, does not collect personal data, and is fully GDPR compliant. It only tracks basic page views and referrer information in an anonymized manner.

iOS App

Our iOS app stores all data locally on your device. We collect minimal anonymized data through Apple's standard App Analytics:

  • App performance metrics (crashes, energy usage)
  • General usage patterns (feature adoption rates)
  • Device type and iOS version (anonymized)

Advertising through Google AdMob: Our app uses Google AdMob to display advertisements. AdMob may collect the following data:

  • Advertising ID (IDFA) for personalized advertising (can be disabled in iOS settings)
  • Device information (device type, operating system version)
  • Location data (if permitted) for location-based advertising
  • App usage data in the context of ad displays

Important: All your tasks and personal data remain exclusively on your device. We have no access to your task content or personal information. Google AdMob processes data according to Google's Privacy Policy.

3. Purpose of Data Processing

Website

We process technical data necessary for website delivery through CloudFront CDN and minimal analytics data through Plausible Analytics for understanding website usage patterns.

iOS App

The anonymized App Analytics data is used solely for:

  • Identifying and fixing app crashes
  • Improving app performance and battery usage
  • Understanding which features are used to guide development

AdMob data is used for:

  • Displaying relevant advertisements
  • Measuring advertising effectiveness
  • Preventing ad fraud
  • Optimizing ad delivery

4. Legal Basis

For the minimal data processing that occurs:

  • Website: Legitimate interests in providing our website (Article 6(1)(f) GDPR)
  • App Analytics: Legitimate interests in app improvement (Article 6(1)(f) GDPR)
  • AdMob Advertising: Legitimate interests in financing the free app (Article 6(1)(f) GDPR) and/or consent for personalized advertising (Article 6(1)(a) GDPR)

5. Data Storage and Security

Website

Our static website files are stored on AWS S3 with encryption at rest. CloudFront provides secure HTTPS delivery.

iOS App

Your personal data never leaves your device. App Analytics data is processed by Apple according to their privacy standards and is only accessible to us in anonymized, aggregated form.

AdMob Data Storage: Google AdMob stores and processes advertising data according to Google's Privacy Policy. Storage duration varies by data type but typically does not exceed 24 months for advertising IDs and associated data.

  • Right to erasure ("right to be forgotten")

  • Right to data portability
  • Right to object to processing
