Privacy Policy
Content updated .
This policy explains what information Mathmatives (https://mathmatives.com) collects, how it is used, and the choices you have.
Calculator inputs
All calculations run in your browser using JavaScript. The values you type into a calculator are never sent to our servers, stored, or shared with anyone.
QR codes and health reminder plans
The QR generator, protein intake calculator and prescription reminder planners process inputs in tab memory without uploading them or saving them in browser storage. These four pages do not load third-party advertising scripts. QR file links remain with the hosting service you choose; we do not upload or host those files or fetch the link to validate its contents. A downloaded QR is readable by anyone who has it, including any Wi-Fi password or contact details encoded in it.
Calendar files contain your event title, dates and reminder times. They are downloaded to your device, not sent to a calendar provider by this website. If you import or share a file, your calendar provider and sharing settings govern that copy. The website itself does not send notifications. Use generic event titles on shared calendars and devices.
Hosting logs
Our hosting provider (Vercel) may record standard server logs, such as your IP address, browser type, the pages requested and the time of the request, to operate and secure the service. These logs are processed under the provider's own privacy policy and are not used by us to identify individuals.
Advertising
We use Google AdSense to show advertising. Google and its partners use cookies and similar technologies (including advertising identifiers) to serve ads based on your visits to this site and other sites, to measure ad performance, and to prevent fraud. 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 opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info.
- Details of how Google uses data from sites that use its services are at policies.google.com/technologies/partner-sites.
Visitors in the European Economic Area, the United Kingdom and Switzerland are shown a consent message before any personalized advertising cookies are set, and can change their choice at any time through that message.
Analytics
We may use privacy-respecting, aggregate analytics to understand which pages are used. If a third-party analytics service that sets cookies is added, this section will be updated to name it.
Cookies
Mathmatives itself does not set cookies. The Online Notepad uses local browser storage only when you select Save draft; you can remove that draft with the New button or by clearing site data. Cookies on this site come only from the advertising and analytics services described above. You can block or delete cookies in your browser settings. The calculators work with cookies disabled.
Children
This site is not directed at children under 13, and we do not knowingly collect personal information from them.
Changes and contact
We will post any changes to this policy on this page and update the date above. Questions about privacy: mathmatives@gmail.com.
