Privacy Policy

Last updated: March 21, 2026

Introduction

Welcome to hakaru.io (“we,” “us,” or “our”). We are committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard information when you visit our website at hakaru.io (the “Site”).

We designed hakaru.io with privacy in mind. We do not require user accounts, we do not collect personal information, and we do not store any data you enter into our tools. Your calculations and inputs stay in your browser.

Information We Collect

We collect minimal data. Specifically:

  • No personal information: We do not ask for your name, email address, phone number, or any other personally identifiable information. There are no user accounts or signups.
  • No tool input storage: Data you enter into our calculators, generators, and other tools is processed entirely in your browser or sent temporarily to a third-party AI service for processing (see “Third-Party Services” below). We do not log, store, or retain any of your tool inputs on our servers.
  • Automatic analytics data: We use Google Analytics 4 (GA4) to collect anonymous, aggregated usage data such as pages visited, time on site, device type, browser type, and approximate geographic region. This data does not identify you personally.

Cookies

We use cookies solely for analytics purposes. Google Analytics 4 sets cookies to distinguish unique visitors and throttle request rates. These are:

  • _ga: Used to distinguish users. Expires after 2 years.
  • _ga_*: Used to persist session state. Expires after 2 years.

We do not use cookies for advertising, tracking across websites, or any purpose other than understanding aggregate site usage. You can disable cookies in your browser settings at any time without affecting the functionality of our tools.

Third-Party Services

We use the following third-party services:

  • Google Analytics 4 (GA4): We use GA4 to understand how visitors use our Site. GA4 collects anonymous usage data and does not collect personally identifiable information through our implementation. You can learn more about Google's privacy practices at policies.google.com/privacy.
  • Google Gemini AI: Some of our AI-powered tools send your input to Google's Gemini API for processing (e.g., generating resume feedback, business names, or meta descriptions). This data is sent in real time and is not stored by us. Google's use of this data is governed by their Gemini API Terms of Service.

Data Security

Our Site is served over HTTPS, ensuring that all data transmitted between your browser and our servers is encrypted. Since we do not collect or store personal data, the risk of a data breach affecting your personal information is minimal. We follow industry best practices to keep our infrastructure secure.

Your Rights

Since we do not collect personal data, there is generally no personal information for us to provide, modify, or delete. However, you have the right to:

  • Opt out of analytics: You can disable cookies in your browser, use a browser extension like Google Analytics Opt-out Browser Add-on, or enable “Do Not Track” in your browser settings.
  • Request information: Contact us if you have questions about what data, if any, we may have related to your visit.

If you are located in the European Economic Area (EEA), United Kingdom, or California, you may have additional rights under GDPR, UK GDPR, or CCPA respectively. Since we do not collect personal data, these rights are largely moot, but please contact us if you have concerns.

Children's Privacy

Our Site is not directed at children under 13. We do not knowingly collect any information from children. Since we collect no personal information from any user, this applies universally.
