Privacy Policy
Last updated: October 10, 2026
This policy explains what information Dayob (https://dayob.com) collects, how it is used, and the choices you have. By using the site you agree to this policy.
Calculator inputs
Our calculators run entirely in your web browser. The numbers you type into a calculator are not sent to our servers and are not stored by us. Closing or reloading the page clears them.
Contact form
When you send a message through our contact form, we store your name, email address, subject, message, the date and time, your browser's user-agent string, and a one-way hashed version of your IP address used only to prevent spam. We use this information solely to reply to you and to improve the site. We do not sell it or add you to a mailing list. Messages are kept for up to 24 months and then deleted; you can ask us to delete yours sooner by emailing contact@dayob.com.
Log data and hosting
Like most websites, our hosting provider automatically records technical information such as browser type, the pages requested, referring page and the time of the request. This data is used for security and to keep the site running and is retained only for a limited period.
Cookies
Cookies are small text files stored on your device. Dayob itself does not use cookies to track you. However, third-party services we use, such as advertising partners, may set cookies as described below. You can block or delete cookies in your browser settings; the calculators will continue to work.
Advertising
We may use Google AdSense to show advertisements. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the internet.
- You may opt out of personalized advertising by visiting Google Ads Settings.
- You can also opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info.
- Learn how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites.
Visitors in the European Economic Area, the United Kingdom and Switzerland will be asked for consent through a certified consent management platform before personalized ads or non-essential cookies are used.
Analytics
If we add privacy-friendly analytics to understand which calculators are used, the data will be aggregated and will not identify you. This policy will be updated before any such tool is enabled.
Children's privacy
Our site is intended for a general audience and is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has sent us personal information, contact us and we will delete it.
Your rights
Depending on where you live (for example under the GDPR or California privacy law), you may have the right to access, correct or delete personal information we hold about you, and to object to certain processing. To make a request, email contact@dayob.com. We will respond within 30 days.
External links
Our pages link to official and third-party websites. We are not responsible for their content or privacy practices.
Changes
We may update this policy from time to time. The "last updated" date above shows when it was last changed.
