This policy explains what information is collected when you use PlenumHub ("we", "us", "the site") at https://plenumhub.com, and how it is used.
Who we are
PlenumHub is operated by Dovydas Jagminas, Aukštagirio g. 18, Vilnius, 10105. You can contact us at dovydasjagm@gmail.com. We are the controller of the personal data described in this policy.
Information you enter into calculators
All calculations happen in your web browser. The values you type into our calculators, such as your weight, age, dates or amounts, are not sent to our servers and we do not store them.
Information collected automatically
Our hosting provider, GitHub Pages, may keep standard server logs that include your IP address, browser type, the pages you request and the time of the request. We use these logs for security and to keep the site running, and we do not combine them with other information about you. We may add privacy-respecting analytics to understand which pages are used; if we do, this policy will be updated.
Cookies
Cookies are small files stored on your device. This site does not need cookies to work and does not set any of its own. Our consent tool stores your consent choice on your device so that it can remember it. Third-party advertising partners, described below, may set cookies or use similar technologies on your device.
Your consent choices
If you are in the European Economic Area, the United Kingdom or Switzerland, we ask for your consent before ads that use cookies or personal data are shown. Visitors in some US states are offered an option to opt out. You can change or withdraw your choice at any time using the "Privacy and cookie settings" link at the bottom of every page. Withdrawing consent does not affect processing that took place before you withdrew it.
Advertising
We show advertisements from third-party advertising networks, including Google. These companies may use cookies, device identifiers and similar technologies to show ads, measure how they perform, and, where permitted, show ads based on your visits to this and other websites.
- Google, as a third-party vendor, uses cookies to serve ads on this site. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the Internet.
- You can read how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites.
- You can opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalised advertising at www.aboutads.info.
We do not control the cookies set by third parties. Please consult those companies' own privacy policies for details.
Why we use information, and our legal basis
We use the limited information we receive to operate and secure the site, understand how it is used so we can improve it, and display advertising that keeps the site free. If the GDPR or UK GDPR applies to you, we rely on:
- Your consent for advertising cookies and personalised ads. You can withdraw it at any time, as described above.
- Our legitimate interests in keeping the site secure, running and improving, using server logs, and in replying to messages you send us.
How long we keep information
Server logs are kept by our hosting provider for a limited period. If you email us, we keep your message and our reply for as long as needed to deal with your enquiry, and for a reasonable period afterwards in case of follow-up questions. Advertising partners keep information under their own policies.
Sharing and international transfers
We share information only with the service providers that help us run the site, such as our hosting provider and our advertising partners. We do not sell your personal information for money. Some of these providers, including Google, may process information outside your country, including in the United States. Where the law requires it, these transfers rely on safeguards such as the EU-US Data Privacy Framework or standard contractual clauses.
Your rights
Depending on where you live, you may have the right to access, correct, delete or restrict the use of personal data held about you, to receive a copy of it, to object to its processing, and to withdraw consent. Because we do not store the data you enter into calculators, we hold very little personal data. To make a request, contact us at dovydasjagm@gmail.com. You also have the right to complain to your local data protection authority, for example the Information Commissioner's Office in the United Kingdom or the data protection authority of your EU country.
US state privacy rights
If you live in California or another US state with a privacy law, you may have the right to know what personal information is collected about you, to request its deletion or correction, to opt out of the "sale" or "sharing" of personal information and of targeted advertising, and not to be treated unfairly for using these rights. We do not sell personal information for money. Cookies used by our advertising partners may count as "sharing" or "targeted advertising" under some of these laws. The personal information involved is identifiers, such as your IP address and cookie IDs, and internet activity, such as the pages you view, collected by our advertising partners and our hosting provider. To opt out, use the "Privacy and cookie settings" link at the bottom of any page, or use Google Ads Settings. For any other request, email dovydasjagm@gmail.com.
Children
This site is not directed at children under 13, or under the age of digital consent in your country, and we do not knowingly collect personal information from them. If you believe a child has given us personal information, email us and we will delete it.
Links to other sites
Our pages may link to external websites. We are not responsible for the content or privacy practices of other sites.
Changes to this policy
We may update this policy from time to time. The date at the top shows when it was last changed.
