Privacy Policy
Your privacy matters to us. This page explains exactly what data we collect, what we do not collect, and how we protect your information.
Last updated: April 13, 2026
The Short Version
Our calculators run entirely in your browser. We never see, collect, or store any birth dates or names you enter. We do not sell data to anyone. We may use basic analytics to understand how people use the site, but we do not track you personally. If you email us, we only use your information to reply and never add you to any mailing list without your permission.
1. Who We Are
Birthday Compatibility is a numerology website operated by Mayank Sahu. Our website address is birthdaycompatibility.co. We provide free online tools including a birthday compatibility calculator and a life path number calculator, along with educational content about numerology and relationship compatibility.
If you have any questions or concerns about this Privacy Policy or our data practices, you can reach us at mail@birthcompatibility.com.
2. Data We Do Not Collect
This is the most important section of this policy. Our tools are designed with privacy as a core principle. Here is what we explicitly do not collect.
Birth Dates
Any dates you enter into our calculators are processed entirely within your web browser using client side JavaScript. The data never leaves your device and is never transmitted to our servers or any third party.
Names
Any names you enter into our tools are handled the same way. They exist only in your browser's memory while you are using the tool and disappear the moment you close or refresh the page.
Calculator Results
Your compatibility scores, Life Path Numbers, and personalized readings are generated locally in your browser. We have no way to see, access, or store any results from your readings.
Passwords or Payment Information
We do not require user accounts and do not process payments. There are no passwords or financial details to collect.
In plain terms: When you use our calculators, the entire process happens on your device. We are technically unable to see what you type, what results you receive, or how many times you use the tools. Your data stays with you.
3. Data We May Collect
While our tools do not collect personal data, there are a few limited ways in which non personal or voluntarily provided information may be collected through the broader operation of the website.
Analytics Data
We may use third party analytics services such as Google Analytics to understand how visitors interact with the website. This may include information such as the pages you visit, how long you spend on each page, the country or region you are visiting from, your device type and browser, and the website or search engine that referred you to us. This data is aggregated and anonymized. It does not identify you personally, and we use it solely to improve the quality and relevance of our website.
Contact Form and Email
If you contact us through our contact page or by email, you voluntarily provide your name, email address, and the content of your message. We use this information only to respond to your inquiry. We do not add your email address to any mailing list, newsletter, or marketing database without your explicit opt in consent. We do not share your contact information with any third party.
Server Logs
Like most websites, our hosting provider may automatically collect basic server log data when you visit the site. This can include your IP address, browser type, referring page, and the date and time of your visit. This data is collected by the hosting infrastructure, not by us directly, and is used for security monitoring and technical troubleshooting purposes only.
4. Cookies and Tracking Technologies
Cookies are small text files stored on your device by your web browser when you visit a website. Here is how cookies may be used on Birthday Compatibility.
Essential Cookies
We may use cookies that are strictly necessary for the Website to function properly. These are limited to technical requirements such as maintaining your session while browsing. These cookies do not track your behavior or collect personal data.
Analytics Cookies
If we use analytics services such as Google Analytics, these services may place their own cookies on your device to collect aggregated usage data. You can opt out of Google Analytics tracking by installing the Google Analytics Opt Out Browser Add On, available at tools.google.com/dlpage/gaoptout. You can also control cookies through your browser settings. Most browsers allow you to refuse cookies, delete existing cookies, or receive a notification before a cookie is stored.
Advertising Cookies
If we display advertisements on the Website in the future, advertising networks may use cookies to show you relevant ads based on your browsing activity. If and when this happens, we will update this section with specific details about which advertising partners are involved and how you can opt out. As of the date of this policy, we do not display third party advertisements on this Website.
Your Cookie Choices
You can manage or delete cookies at any time through your browser settings. Please note that disabling certain cookies may affect your experience on the Website, though our core tools will continue to function normally since they do not depend on cookies.
5. How We Use Information
Any information we do collect is used strictly for the following purposes. To respond to your inquiries when you contact us. To understand general website usage patterns through aggregated analytics so we can improve our content and tools. To maintain the security and technical stability of the Website. To comply with legal obligations if required by law.
We do not use any collected information for profiling, targeted advertising, automated decision making, or any purpose beyond what is described in this policy.
6. Data Sharing and Third Parties
We do not sell, rent, trade, or otherwise share your personal information with any third party for commercial purposes. Period.
The only circumstances under which information might be shared are as follows. With hosting and analytics service providers who process data on our behalf and are bound by their own privacy policies (such as Google Analytics and our hosting provider). If required by law, regulation, legal process, or governmental request. To protect the rights, property, or safety of Birthday Compatibility, our users, or the public.
If we ever introduce new third party integrations that handle user data, we will update this policy before implementing them and will clearly disclose the nature of the integration.
7. Data Retention
Since our calculators do not transmit any data to our servers, there is nothing for us to retain from tool usage. The data exists only in your browser and disappears when you close or refresh the page.
If you contact us by email, we retain your correspondence for as long as reasonably necessary to respond to your inquiry and maintain a record of our communication. If you request that we delete your email correspondence, we will do so promptly upon receiving your request.
Analytics data collected through third party services is retained according to the retention policies of those services. For Google Analytics, the default retention period is 14 months, after which the data is automatically deleted.
8. Data Security
We take reasonable measures to protect the information associated with this Website. Our site is served over HTTPS, which encrypts data transmitted between your browser and our servers. Our hosting environment is maintained with current security patches and standard industry protections.
However, no method of electronic transmission or storage is completely secure. While we strive to protect any information within our control, we cannot guarantee absolute security. The most effective protection our tools offer is architectural: since calculator data never leaves your device, there is nothing for anyone to intercept or breach on our end.
9. Your Rights
Depending on your location, you may have certain rights regarding your personal data. These may include the right to access any personal information we hold about you, the right to request correction of inaccurate information, the right to request deletion of your data, the right to object to or restrict certain processing of your data, the right to data portability, and the right to withdraw consent at any time where processing is based on consent.
Since we collect minimal data, these rights primarily apply to email correspondence. If you would like to exercise any of these rights, please contact us at mail@birthcompatibility.com and we will respond within 30 days.
For Users in the European Economic Area (GDPR)
If you are located in the European Economic Area, you have additional rights under the General Data Protection Regulation. The legal basis for any data processing we perform is either legitimate interest (for analytics and website improvement) or your explicit consent (for email communication). You have the right to lodge a complaint with your local data protection authority if you believe your rights have been violated.
For Users in California (CCPA)
If you are a California resident, you have the right to know what personal information we collect, request deletion of your personal information, and opt out of the sale of your personal information. We do not sell personal information to any third party. To exercise your rights under the CCPA, please contact us at the email address provided above.
For Users in India
If you are located in India, your data is protected under the Digital Personal Data Protection Act. You have the right to access, correct, and erase your personal data, as well as the right to withdraw consent. Since our tools process data locally on your device, your calculator data is inherently protected by design. For any data we do hold (such as email correspondence), you may exercise your rights by contacting us directly.
10. Children's Privacy
Birthday Compatibility is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. Since our calculators do not collect any data at all, children who use our tools are not at risk of data collection. However, if you are a parent or guardian and believe that your child has provided us with personal information through our contact form, please contact us immediately and we will take steps to delete that information.
11. International Users
Birthday Compatibility is operated from India and our website is accessible globally. If you access the Website from outside India, please be aware that any information you voluntarily provide through our contact form may be transferred to and processed in India. By using the Website, you consent to this transfer. We will take all reasonable steps to ensure that your data is treated securely and in accordance with this Privacy Policy regardless of where it is processed.
12. Links to Other Websites
Our Website may contain links to third party websites that are not operated by us. We have no control over the content, privacy policies, or practices of these external sites. We encourage you to review the privacy policy of every website you visit. A link from our Website does not imply endorsement, and we accept no responsibility for the privacy practices of third party sites.
13. Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. When we make changes, we will revise the "Last updated" date at the top of this page. If we make material changes that significantly affect how we handle your data, we will provide prominent notice on the Website before the changes take effect.
