Our Chrome extensions are designed to process only the data necessary to provide their stated user-facing features. The exact data processed depends on the specific extension, permissions requested, and features enabled by the user.

1. Scope

This Privacy Policy applies to Chrome extensions, related websites, license services, support services, and optional external integrations provided by us. It does not replace the privacy policies of third-party websites, AI providers, cloud services, payment providers, or other services that users choose to connect or use.

2. Data We May Process

Data type Purpose Typical storage or transfer
Extension settings and preferences To save user-selected options, workflow preferences, interface settings, feature configuration, and local task state. Usually stored locally in the user’s browser using Chrome extension storage.
Website or page content accessed by the extension To provide the extension’s user-facing functionality, such as reading, processing, summarizing, exporting, filling, copying, analyzing, or transforming content requested by the user. Processed locally where possible. May be sent to configured external services only when required for enabled features.
User-provided content To process text, prompts, notes, messages, files, forms, tasks, or other content entered or selected by the user. Stored locally, processed temporarily, or sent to a configured service depending on the feature.
Authentication data, API keys, or access tokens To connect to third-party services selected by the user, such as AI providers, cloud services, automation services, or other APIs. Stored locally in the user’s browser unless otherwise disclosed. Users can revoke or rotate keys through the relevant provider.
License or activation data To activate paid access, verify license status, prevent abuse, provide support, and maintain service security. May be sent to our license server. This may include license key or hash, extension ID, installation ID, version, website/domain when relevant, IP address, user agent, verification result, and timestamps.
Technical and diagnostic information To troubleshoot errors, improve reliability, prevent abuse, and support security investigations. May be stored locally or included in support requests or server logs when a related online service is used.

3. How We Use Data

  • To provide the extension’s stated single purpose and user-facing features.
  • To save extension settings and local workflow progress.
  • To process content that the user chooses to open, select, enter, analyze, export, or transform.
  • To call third-party services configured or enabled by the user.
  • To verify licenses, subscriptions, or paid feature access where applicable.
  • To provide support, fix errors, prevent abuse, and improve reliability.

4. Data We Do Not Sell or Use for Advertising

We do not sell user data. We do not transfer user data to advertising platforms, data brokers, or information resellers. We do not use user data for personalized advertising, retargeting, interest-based advertising, creditworthiness, or lending purposes.

5. Chrome Web Store Limited Use Disclosure

The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements. We use Chrome API data only to provide or improve the extension’s single purpose and user-facing functionality. We do not use Chrome API data for unrelated tracking, advertising, resale, or any purpose not disclosed to users.

6. Local Storage

Many extension features store data locally in the user’s browser, such as settings, preferences, temporary task state, cached results, local logs, license status, and API configuration. Users can remove local extension data by clearing browser extension data, disabling the extension, or uninstalling the extension.

7. External Services

Some extensions may connect to external services only when necessary for enabled features. These services may include license verification servers, AI providers, cloud APIs, automation services, email or messaging services, payment providers, or other APIs selected by the user.

When an external service is used, the extension may send only the data necessary for the requested feature. For example, AI-assisted features may send selected text, prompts, page content, user instructions, or related context to the AI provider configured by the user. License services may receive license and device verification data. Each third-party service is governed by its own terms and privacy policy.

8. AI Features

If an extension includes AI-assisted features and the user enables or configures them, relevant content may be sent to the selected AI provider to generate summaries, drafts, analysis, classifications, reports, or other requested outputs. Users are responsible for reviewing the privacy policy, terms, pricing, and data handling practices of the AI provider they choose. Users should avoid submitting unnecessary sensitive personal information to AI services.

9. Human Access to User Data

We do not allow humans to read user data except where the user gives explicit consent for support, where access is necessary for security or abuse investigation, where required by law, or where data has been aggregated and anonymized for internal operations.

10. Data Sharing

We share data only when necessary to provide or improve the extension’s disclosed functionality, comply with applicable law, protect against security threats or abuse, process license or service requests, or operate third-party integrations configured by the user. We do not sell user data or share it for unrelated purposes.

11. Security

We use reasonable security measures such as HTTPS transmission, access controls, local browser storage, permission checks, input validation, and limited data collection. No method of transmission or storage is completely secure, and users should keep Chrome, extensions, operating systems, and API credentials up to date and protected.

12. User Control

  • Users can disable or uninstall an extension at any time.
  • Users can clear local extension data from Chrome.
  • Users can revoke or rotate third-party API keys through the relevant provider account.
  • Users can disable optional features that require external services.
  • Users can contact us for privacy, support, license, or data-related requests.

13. Children’s Privacy

Our extensions are not intended for children under 13 and are not designed to knowingly collect personal information from children.

14. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our extensions, services, legal requirements, or Chrome Web Store policies. The updated version will be posted on this page with a new “Last updated” date.
