Effective Date 27.08.2025

Thank you for using the Quark Browser Extension. Your privacy is important to us. This Privacy Policy explains how we collect, use, and protect your data when you use our product

Information We Collect

We strive to collect the minimal amount of personal data necessary to provide and improve our services. The Extension does not collect any personally identifiable information (PII) unless explicitly authorised by the user

Data We May Collect

• Blocked Sites and App Settings
  We store configuration details, including websites you choose to block, schedule settings, timer sessions, and other preference data
• Focus Session Logs
  To provide usage analytics and progress tracking, we may store anonymous session logs, including session duration, block types, and timestamps
• Extension Usage Analytics Optional
  With your consent, we may collect anonymised, aggregated usage data, e.g., number of sessions created, feature usage frequency, to improve the Extension’s performance and user experience

How We Use Your Data

The data we collect is used strictly for the following purposes:

• To operate and personalise your experience with the Extension
• To provide feedback, analytics, and insights on your focus and screen time
• To improve our services and develop new features
• To ensure the reliability and security of the Extension

Data Storage and Security

We use industry-standard security measures to protect the data you share with us

• All settings and session data are stored locally in your browser unless the user explicitly enables synchronisation
• If optional analytics are enabled, the data is anonymised and transmitted securely to our servers
• We do not sell, rent, or share your data with third parties for advertising or marketing purposes

Third-Party Services

The Quark Extension uses Google Analytics to collect anonymous usage data. This helps us understand how the extension is used, improve performance, and enhance user experience.

User Controls

You are in control of your data

• You may clear or reset all stored data via the Extension settings
• You may disable or delete the Extension at any time
• If analytics are enabled, you may opt out at any time through the settings menu

Children’s Privacy

Our Extension is not intended for use by individuals under the age of 13. We do not knowingly collect data from individuals under the age of 13. If we become aware of such data being collected, we will delete it promptly.

Changes to This Policy

We reserve the right to update this Privacy Policy from time to time. Any changes will be posted within the Extension and on our website, with the “Effective Date” updated accordingly. Continued use of the Extension after changes constitutes your consent to the updated policy.
