Privacy Policy
Last updated: March 2026
Introduction
Calqel ("we", "us", "our") operates the website calqel.com. This page informs you of our policies regarding the collection, use and disclosure of information when you use our service.
Information We Do Not Collect
Calqel does not require any account creation, login, or registration. We do not collect names, email addresses, phone numbers, or any other personally identifiable information. All calculations are performed locally in your browser and are never sent to our servers.
Local Storage
Some features (such as Quick Notes and currency preference) store data locally in your browser using localStorage. This data stays on your device and is never transmitted to us. You can clear it at any time by clearing your browser data.
Analytics
We may use privacy-respecting analytics tools to understand general usage patterns (e.g. which pages are visited most). No personal data or calculator inputs are collected as part of analytics. Aggregate, anonymised data only.
Cookies
Calqel uses only essential cookies required for the site to function correctly (e.g. language preference). We do not use tracking cookies or third-party advertising cookies.
Third-Party Services
We do not sell, trade, or transfer your information to third parties. The site may load fonts or icons from CDNs; these providers have their own privacy policies.
Children's Privacy
Calqel does not knowingly collect any data from children under the age of 13. If you believe a child has provided us with personal information, please contact us so we can delete it.
Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date. Continued use of the site after changes constitutes acceptance of the new policy.
