ClockinSync — World Clock & Timezone Converter

Last updated: April 21, 2026

ClockinSync (“we,” “our,” or “us”) operates the ClockinSync Chrome extension and the website www.clockinsync.com (collectively, the “Service”). This Privacy Policy explains what data we collect, how we use it, and your rights regarding that data.

By using the Service, you agree to the collection and use of information as described in this policy.


1. Information We Collect

1.1 Anonymous Device Identifier

When you first use the ClockinSync extension and accept the onboarding notice, a random identifier (UUID) is generated on your device. This identifier is not linked to your name, email, or any personal information. It is used solely to associate your device with free plan usage limits. You may opt out of transmitting this identifier to our servers via Settings > Usage Statistics.

1.2 Feature Usage Statistics

We collect anonymous, aggregate counts of feature usage per week, including the number of times you use the /time shortcode, page annotations, natural language input, and popup opens. These counts are used to enforce free plan limits and to understand which features are most valuable. No page content, URLs visited, or browsing history is included. You may disable usage reporting at any time via Settings > Usage Statistics. When disabled, usage is tracked locally on your device only (for plan limit enforcement) and is not transmitted to our servers.

1.3 Account Information

If you choose to sign in with Google, we collect and store your email address and display name as provided by Google's OAuth2 service. We do not access your Google contacts, calendar, Gmail, or any data beyond your basic profile information (email and name). Your Google OAuth token is used solely to verify your identity with Google's servers during sign-in and is not stored on our servers after verification.

1.4 Cloud Sync Data

If you voluntarily enable Cloud Sync in the extension settings, your timezone configurations, clock profiles, reminders (including titles and scheduled times), and preferences are transmitted to and stored on our server at api.clockinsync.com. When changes are made to your synced data, they are automatically pushed to the server so that your other devices receive the updates. You may also optionally store this data in your Google Drive application data folder, which is accessible only to ClockinSync and not to any other application. Cloud Sync is entirely opt-in and can be disabled at any time from Settings.

1.5 Payment Information

If you purchase a plan upgrade, payment is processed by Stripe, Inc. We do not receive, process, or store your credit card number, bank account details, or other financial information. We receive only a confirmation of payment, the amount paid, and your email address from Stripe for the purpose of activating your plan. Please refer to Stripe's Privacy Policy at https://stripe.com/privacy for details on how Stripe handles your payment data.

1.6 Page Content

The ClockinSync content script runs on web pages you visit to detect timezone expressions in text (such as “3:00 PM EST”). This text is analyzed entirely on your device using local pattern matching. No page content, URLs, form data, passwords, or browsing activity is ever transmitted to our servers. The content script does not read, access, or modify any form inputs, login credentials, or sensitive page data.

1.7 Website Analytics

Our website www.clockinsync.com uses Google Analytics to collect standard usage data, including your IP address, browser type, pages visited, time spent on pages, and referring URLs. This data is collected by Google and is subject to Google's Privacy Policy at https://policies.google.com/privacy. We use this information solely to understand website traffic and improve our website. Google Analytics data is not linked to your ClockinSync extension account or usage data. You may opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on at https://tools.google.com/dlpage/gaoptout.

1.8 License and Configuration Polling

The extension periodically contacts our server (approximately every five minutes) to retrieve your current plan status, feature limits, and any active notifications from us. This request includes your authentication token and device identifier. This polling is necessary for the Service to function and cannot be independently disabled while the extension is installed.


2. How We Use Your Information

We use the information collected for the following purposes:


3. Information Sharing and Disclosure

We do not sell, rent, trade, or otherwise share your personal information with third parties, except in the following limited circumstances:

We do not serve advertisements in the ClockinSync extension or on our website. We do not share data with advertising networks or data brokers.


4. Data Storage and Security

Your data is stored on secure servers operated by our hosting provider. We employ industry-standard security measures, including encrypted data transmission (HTTPS/TLS) for all communications between the extension and our servers, and access controls to limit who can access user data.

Authentication tokens are stored locally in your browser's extension storage (chrome.storage.local), which is accessible only to the ClockinSync extension. Passwords are never collected or stored by ClockinSync.

While we strive to protect your information, no method of electronic transmission or storage is completely secure. We cannot guarantee absolute security.

8. International Data Transfers

Your information may be transferred to and processed in countries other than your country of residence. These countries may have different data protection laws. By using the Service, you consent to the transfer of your information to these countries. We take appropriate safeguards to ensure your data is protected in accordance with this Privacy Policy.


9. Third-Party Links

The Service may contain links to third-party websites or services. We are not responsible for the privacy practices of these third parties. We encourage you to review the privacy policies of any third-party service you interact with.


10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. When we make material changes, we will update the “Last updated” date at the top of this page and may notify you via an in-app notification in the extension. Your continued use of the Service after changes are posted constitutes your acceptance of the revised policy.
