Data Storage and Security

Local-First Architecture

ClockZen is built with a privacy-first, local-first approach. By default, your activity tracking data is stored locally on your device and never transmitted to our servers. You have complete control over your data.

Optional Cloud Sync

If you choose to enable cloud sync for cross-device access, your data is encrypted in transit (TLS 1.3) and at rest (AES-256). Even with cloud sync enabled, we cannot read your activity data.

Security Measures

We implement appropriate technical and organizational security measures to protect your personal information, including encryption, secure infrastructure, and regular security audits.

Data Sharing

We do not sell your personal information. We may share your information only in these circumstances:

  • Service Providers: With trusted third parties who assist us in operating our services (e.g., hosting, payment processing)
  • Legal Requirements: When required by law or to respond to legal process
  • Business Transfers: In connection with a merger, acquisition, or sale of assets
  • With Your Consent: When you explicitly consent to sharing

Your Rights and Choices

You have the right to:

  • Access: Request a copy of your personal data
  • Correction: Update or correct inaccurate information
  • Deletion: Request deletion of your personal data
  • Export: Export your data in a machine-readable format
  • Opt-out: Opt out of marketing communications

Data Retention

We retain your account information for as long as your account is active. If you delete your account, we will delete your personal information within 30 days, except where retention is required by law.

Local activity data is stored on your device and retained according to your preferences. You can delete this data at any time through the app settings.

Children's Privacy

ClockZen is not intended for use by children under 13 years of age. We do not knowingly collect personal information from children under 13. If we learn we have collected such information, we will delete it promptly.

International Data Transfers

Your information may be transferred to and processed in countries other than your own. We ensure appropriate safeguards are in place to protect your information in accordance with this Privacy Policy.
