Privacy Policy

Last updated: June 2026

1. Introduction

Welcome to MySleepTool.com. This Privacy Policy explains how we collect, use, and protect information when you use our website. We are committed to protecting your privacy and being transparent about our data practices.

MySleepTool.com provides free online calculators for sleep, health, and personal finance. We operate with a minimal data collection approach: our calculators run client-side in your browser and we do not receive or store any values you input.

2. Information We Collect Automatically

When you visit our website, our hosting provider and analytics services automatically collect limited technical information:

• IP address (may be anonymized depending on your location and consent settings)
• Browser type, version, and operating system
• Pages visited, time spent on each page, and navigation paths
• Referring website (which site sent you to us)
• Date and time of your visit
• Device type (mobile, desktop, tablet)

We do not collect any personal information you enter into our calculators. All calculation inputs — your weight, salary, sleep time, loan amount, or any other values — are processed locally in your browser and are never transmitted to our servers.

3. Cookies and Tracking Technologies

We use the following types of cookies and tracking technologies:

• Essential cookies: Required for basic website functionality and security. Cannot be disabled without affecting site operation.
• Analytics cookies: We may use Google Analytics (with IP anonymization enabled) to understand aggregate visitor behavior — how many people visit, which calculators are popular, and how users navigate the site. This data is aggregated and anonymous.
• Advertising cookies: We use Google AdSense to display relevant advertisements. Google uses cookies to personalize ads based on your browsing history across the web. You can opt out of personalized advertising through your Google account settings.

You can manage cookie preferences through your browser settings. Disabling all cookies may affect some website functionality.

4. Google AdSense and Advertising

This website uses Google AdSense to display advertisements. Google AdSense uses cookies and web beacons to show you ads that may be relevant to your interests based on your prior browsing activity across websites that use Google's advertising services.

Google's advertising partners may use cookies to collect data about your visits to this and other websites to provide targeted advertisements. This data collection is subject to Google's Privacy Policy.

5. How We Use Information We Collect

The limited technical information we collect is used to:

• Operate and maintain the website and ensure it functions correctly
• Understand aggregate usage patterns to improve our calculators and content
• Monitor for security threats and protect against abuse
• Display relevant advertisements through Google AdSense
• Comply with legal obligations where applicable

We do not sell, rent, or trade your information to third parties for their marketing purposes.

6. Third-Party Services

We share limited anonymized data with the following third-party services necessary to operate the website:

• Google Analytics: Anonymized website usage statistics. Data is processed under Google's privacy terms. You can opt out using the Google Analytics Opt-out Browser Add-on.
• Google AdSense: Ad serving and personalization. Subject to Google's privacy terms.
• Hostinger (web hosting): Server infrastructure. Processes server logs including IP addresses for security and operation purposes.
• Google Fonts: Font delivery service. Google may log the request for fonts, including your IP address.

7. Data Retention

Server access logs are retained for up to 30 days for security and technical purposes, after which they are automatically deleted. Analytics data is retained for up to 14 months in Google Analytics (our default setting). We do not retain calculator input data because we never receive it in the first place.

8. Your Rights

Depending on your location and applicable law, you may have the following rights regarding your personal data:

• Access: Request a copy of personal data we hold about you
• Correction: Request correction of inaccurate data
• Deletion: Request deletion of your personal data

10. GDPR (European Users)

If you are located in the European Economic Area (EEA), United Kingdom, or Switzerland, you have rights under the General Data Protection Regulation (GDPR) or equivalent legislation.

12. Security

We implement reasonable technical and organizational measures to protect the limited information we collect against unauthorized access, alteration, disclosure, or destruction. However, no internet transmission or electronic storage is completely secure, and we cannot guarantee absolute security.

13. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. We will post the updated policy on this page with a revised "Last updated" date. For material changes, we may provide additional notice. Your continued use of the website after changes are posted constitutes your acceptance of the updated policy.
