Privacy policy
Last updated: 1 October 2026
The short version
Bloguu does not have user accounts, a database or a server that processes your calculations. Every figure you type into a calculator is handled by your own browser and never transmitted to us. We do serve third-party advertising, and those advertisers set their own cookies. That is the main way your data is touched here, and this page explains it.
What we collect directly
Nothing that identifies you, with one exception. If you send a message through the contact form, your name, email address and message are transmitted to Formspree, the third-party service that delivers that form and then to our email inbox. We keep those messages for as long as needed to respond and to track reported errors.
Calculator inputs
Your inputs stay in your browser. They are used to compute a result, and they are written into the page address so that refreshing or sharing the link reproduces the result. This means that if you share a link, whoever receives it can see the values in it. That is the intended behavior, but be aware of it before sharing a calculation containing figures you consider private.
Local storage
A few preferences are saved in your browser's local storage: your light or dark theme, the currency you picked (if you picked one instead of leaving it on Auto), and the units you chose for height, weight and similar boxes. These never leave your device and contain no personal information. Clearing your browser data removes them.
Google AdSense and advertising cookies
This site displays advertising served by Google AdSense. Google and its partners use cookies and similar technologies to serve ads based on your prior visits to this and other websites.
Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and other sites on the internet. You can opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of third-party vendor cookies for personalized advertising at aboutads.info.
Third-party vendors, including Google, may serve ads on this site and may use cookies to serve ads based on a user's prior visits. Bloguu does not control what data these vendors collect and cannot access it.
For more on how Google handles data from sites that use its services, see Google's partner sites policy.
Your consent choices
Visitors in the European Economic Area, the United Kingdom and Switzerland are asked for consent through Google's certified consent message before advertising cookies or personalized ads are used. You can change or withdraw that choice at any time with the Privacy settings link in the footer of every page. Elsewhere, you can control personalized ads through the opt-out links above.
Analytics
Bloguu does not run its own analytics or tracking scripts. We use Google Search Console to see how the site appears in Google search; it reports only aggregate search data, such as how often a page was shown and clicked, and sets no cookies on this site. If we add an analytics service in future, this section will be updated to name it before it goes live.
Cookies in summary
- Advertising cookies. Set by Google and its partners to select and measure ads. Controlled through the opt-out links above or your browser settings.
- Consent cookie. Set by Google's consent message to remember the choice you made, where that message applies.
- No cookies are set by Bloguu itself. Our stored preferences use local storage, not cookies, and are not transmitted anywhere.
You can block or delete cookies in any modern browser's settings. Blocking advertising cookies does not stop ads appearing; it makes them less relevant.
Links to other sites
Some pages link to external sites for sources or further reading. Once you follow such a link you are subject to that site's privacy practices, not ours. We have no control over their content or their data handling.
Children's privacy
This site is not directed at children under 13 and we do not knowingly collect information from them. If you believe a child has sent us personal information through the contact form, write to us and it will be deleted.
Your rights
Because we hold almost no personal data, there is usually nothing to request or erase. If you have contacted us by email or through the form, you may ask for that correspondence to be deleted at any time.
Changes to this policy
Material changes will be reflected in the date at the top of this page. Continued use of the site after a change constitutes acceptance of the revised policy.
