Privacy Policy

Calcmemo has no registration, login, or checkout. It does not ask for your name, postal address, phone number, payment method, or identification number to use a calculator.

Calculations run in your browser. Calcmemo does not operate a database of calculator entries. Some calculators put inputs in the page URL so a result can be bookmarked or shared; a URL requested from the site can appear in ordinary hosting and security logs. Do not enter confidential information into a calculator or share a result URL that you consider sensitive.

Cloudflare hosts and protects the site and provides Web Analytics. Its analytics service is configured without analytics cookies and is used to understand page views, device and browser types, and approximate country-level traffic rather than identify individual visitors.

Read Cloudflare's own Web Analytics information. Cloudflare may retain request logs for security, reliability, and abuse prevention under its policies.

Calcmemo uses Google AdSense. Google and other advertising providers may use cookies, device data, and activity on this and other sites to deliver and measure ads. Calcmemo does not choose the individual ad shown to you.

You can manage personalised advertising in Google Ads Settings. Google explains its use of data in its advertising policy.

Affiliate shopping links are currently paused site-wide, so Calcmemo is not loading Coupang product images or links. They may be restored later only on pages where a product link is directly useful and relevant; any restored link will carry a visible commission disclosure, and this policy will describe the related data flow.

Google and Cloudflare are based in the United States and process data under their own policies. Calcmemo does not receive a visitor-level copy of their advertising or analytics profiles.

If you email Calcmemo, the message includes the address and information you choose to send. It is used to reply, investigate a correction, or act on the request, and may be retained as needed to track that work. Email service providers necessarily process the message for delivery. Do not send identification numbers, payment information, medical records, or other sensitive personal data.

Material changes will be posted on this page with a new update date. Privacy questions can be sent to [email protected]. The same address is on the contact page.
