Privacy Policy
Updated June 12, 2026
This Privacy Policy explains how calcetera (“we”, “us”) handles information when you use our website. We aim to collect as little as possible.
This policy is a starting template and should be reviewed by a qualified legal professional before launch to ensure it reflects your actual operations and the laws of the regions you serve.
The tools themselves
Our calculators, converters and text tools run entirely in your browser. The text and numbers you enter are processed locally and are not sent to or stored on our servers.
Information we process
- Essential, anonymous technical data needed to serve the site (for example, your request is handled by our hosting/CDN provider).
- Analytics data, only with your consent — aggregated, anonymized usage such as which pages are visited, to help us improve the tools.
- Advertising data, only with your consent — used by our advertising partner to show ads and, where permitted, personalize them.
Cookies and consent
We use cookies and similar technologies. Strictly necessary cookies (such as remembering your privacy choices) are always active. Analytics and advertising cookies are only set after you consent. You can review or change your choices at any time via Cookie settings in the footer. See our Cookie Policy for details.
For visitors in the EEA, UK and other applicable regions, we use Google Consent Mode so that analytics and advertising tags respect your choices.
Third-party partners
- Google AdSense (advertising) — see Google’s privacy policy.
- Google Analytics (measurement) — see Google’s privacy policy.
These partners may process data as independent controllers in accordance with their own policies.
Your rights
Depending on where you live, you may have rights to access, correct, delete or restrict the processing of your personal data, and to withdraw consent at any time. To exercise these rights, contact us at the address below.
Data retention
We do not retain the content you enter into the tools. Analytics and advertising data are retained by the respective providers according to their policies.
Changes
We may update this policy from time to time. The “last updated” date above reflects the latest revision.
