This policy explains how Calculators ("we", "us") handles information when you use this website.
The numbers you enter into our calculators are processed in your browser and are not sent to or stored on our servers. We do not require accounts. Like most websites, our hosting provider may keep standard server logs (IP address, browser type, pages visited).
We use Google AdSense to display ads. Google and its partners use cookies, including the DoubleClick cookie, to serve ads based on your visits to this and other websites. You can opt out of personalised advertising at Google Ads Settings or aboutads.info. Learn more at How Google uses information from sites that use its services. Third-party vendors, including Google, use cookies to serve ads based on prior visits. Visitors in the EEA, UK and Switzerland may be asked for consent to personalised ads.
The currency converter requests exchange rates from open.er-api.com. Only your browser's standard request data is shared with that service. Calculators otherwise make no external requests.
This site is not directed to children under 13 and we do not knowingly collect their data.
Depending on where you live, you may have rights to access or delete data we hold about you. Contact oneclicktool.tech@gmail.com with any request.
We may update this policy and will change the date above when we do.
