This Privacy Policy explains how CritterCalc (“we”, “us”) collects and uses information when you visit crittercalc.com (the “Site”).
Information you type into calculators
Our calculators run in your web browser. The values you enter, such as your pet’s weight or a date, are processed on your device and are not sent to or stored by us.
Information you send us
If you use our contact form, we receive your name, email address and message. We use this only to reply to you and to improve the Site. We don’t sell it or add you to a mailing list without your permission.
Automatically collected information
Like most websites, our hosting provider automatically records basic technical data, such as IP address, browser type, pages visited and the time of your visit, for security and performance. We may also use analytics tools (for example Google Analytics) that use cookies to help us understand how visitors use the Site. This data is aggregated and not used to identify you personally.
Cookies and advertising
We may show ads from third-party vendors, including Google. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this Site or other websites. Google’s use of advertising cookies enables it and its partners to serve ads based on your visits to this and other sites on the Internet.
You can opt out of personalized advertising by visiting Google Ads Settings or www.aboutads.info. You can also block or delete cookies in your browser settings; the calculators will still work.
Where required by law (for example in the EEA, UK or certain US states), we will ask for your consent before setting non-essential cookies, and you can change your choice at any time.
Your rights
Depending on where you live, you may have the right to access, correct or delete personal information we hold about you, or to object to certain processing. To make a request, contact us. California residents can ask us not to “sell” or “share” personal information; we do not sell personal information.
Children
The Site is intended for a general audience and is not directed at children under 13. We don’t knowingly collect personal information from children.
Data retention and security
We keep contact messages only as long as needed to respond and for our records. We use reasonable measures, including HTTPS encryption, to protect information, but no method of transmission over the Internet is completely secure.
Changes
We may update this policy from time to time. The “Last updated” date above shows when it last changed.
