Privacy policy
The short version
Smart Tile Calculator has no accounts and no logins. The numbers you type into a calculator are processed in your browser and are never sent to us or stored on our servers.
Information we collect
- Nothing you enter into a calculator. All calculations run locally in your browser.
- Anonymous usage data. Aggregate analytics such as page views, referring site, approximate region, device type and browser.
- Visit notifications. When you open a page, our server reads your IP address to look up an approximate city/region (via a geo-IP service) and sends a real-time visit alert to the site owner. The IP address is used for that lookup in the moment and is not stored in a database.
- Email you send us. If you contact support, we keep the message only as long as needed to answer it.
Cookies and third parties
We use analytics cookies to understand which calculators people use. When you click an Amazon link, Amazon may set its own cookies to attribute a purchase to this site — that is governed by Amazon's privacy notice, not ours. See our cookie policy for details.
Advertising (Google AdSense)
We show ads served by Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your 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 visit to this site and/or other sites on the Internet. Google and its partners use cookies (including the DoubleClick cookie) and similar technologies to serve ads based on your prior visits to this and other websites, and to measure ad performance. 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 can opt out of personalised advertising at Google Ads Settings or at aboutads.info. Learn more in How Google uses information from sites that use its services.
Consent (EEA, UK and Switzerland)
Visitors in the European Economic Area, the United Kingdom and Switzerland are shown a consent message provided by Google, a certified consent management platform, before personalised ads or advertising cookies are used. You can accept, decline, or change your choice at any time through the privacy/consent link that message provides. If you decline, Google may still show non-personalised ads that use cookies only for frequency capping, aggregated reporting and fraud prevention.
Your rights
Because we do not collect personal identifiers, there is generally no personal data for us to access, correct or delete. If you have emailed us and want that correspondence removed, ask and we will delete it. Depending on where you live, you may have rights under the GDPR or CCPA; we honour those requests.
Children
This site is not directed to children under 13 and we do not knowingly collect information from them.
Changes
We will update this page if our practices change, and the date at the bottom of the page will reflect the revision.
