Privacy Policy
Last Updated: June 2026. Learn how we protect your digital footprint on HelloTools.
Our Core Promise
HelloTools is engineered to operate directly in your web browser. All calculations, text analysis, and developer conversions are performed locally on your computer. Your raw inputs never touch our servers.
1. Information We Collect
We do not collect or store any personal data or input values entered into our calculators and utility tools. Any numbers, formulas, or text you input remain completely private inside your local browser memory and are deleted once the tab is closed.
We do, however, collect anonymous diagnostic data through third-party tools to help optimize site performance:
- Analytics & Diagnostics: We use Vercel Analytics and Speed Insights to record anonymous pageviews, load speeds, and device/browser categories. No IP addresses or identifying details are logged.
- Log Data: Like most websites, our host automatically collects server logs (e.g., HTTP request methods, response codes, and referral page urls) for stability and security monitoring.
2. Google AdSense & Third-Party Cookies
We serve advertisements through Google AdSense to keep our service 100% free. Google and third-party vendors use cookies to serve ads based on your previous visits to our website or other sites on the internet.
Important Cookie Info:
- Google’s use of advertising cookies enables it and its partners to serve ads based on your visit to HelloTools and other sites on the Internet.
- You may opt-out of personalized advertising by visiting the Google Ads Settings page.
- Alternatively, you can opt-out of a third-party vendor's use of cookies for personalized advertising by visiting the www.aboutads.info page.
3. Your Privacy Rights (GDPR & CCPA)
Depending on your location, you may have specific data rights:
- GDPR (European Users): Under the General Data Protection Regulation, you have the right to request access to, correction of, or deletion of any telemetry data we hold. Since we store no personal IDs, there is typically no data linked to your identity.
- CCPA (California Users): Under the California Consumer Privacy Act, you have the right to know what personal data is collected and opt out of the "sale" of personal data (which includes personalized advertising cookie collection). You can control your ad preferences using the links in Section 2.
4. Data Security
We use industry-standard HTTPS/TLS encryption to secure all transmissions between your browser and our servers. Because all calculations take place within your local browser, your numeric inputs are shielded from network intercepts and server database leaks.
