Data we process
Calculator values are processed in your browser. We do not require an account or ask for identifying information to use the tools.
Analytics and preferences
With your consent, anonymous usage events may be collected to improve the service. Theme, language and cookie preferences can be stored on your device.
Your choices
You can change cookie preferences from the site and clear locally stored preferences through your browser.
Advertising and service providers
After site approval, Google AdSense may process device, advertising and consent information to deliver and measure ads. Cloudflare provides site delivery, security and aggregate analytics. Their own privacy terms may also apply.
Retention and security
Records are retained only as long as needed for service operation, security, error investigation or legal obligations, then deleted or anonymised. Reasonable technical and organisational safeguards are used, although internet transmission cannot be guaranteed to be completely secure.
For access, correction, deletion or other privacy requests, contact sertacgltkn@gmail.com and identify the relevant request.
