Who Controls This Site
Calxo AI is the data controller for this website. For privacy requests, contact privacy@calxo.ai.
Calculator Inputs
Calculator inputs are processed in your browser where possible. We do not require an account to use the calculators. If you request an AI explanation, the calculator name, inputs, results, and built-in notes are sent to the AI explanation endpoint so the response can be generated.
Local Preferences and Cookies
Necessary local storage may remember your theme, recent calculator history, and privacy preference. Google Analytics and Meta Pixel are loaded only after you accept optional analytics. If your browser sends Do Not Track, optional analytics are treated as rejected.
Feedback
If you submit a like, dislike, or suggestion, we store the calculator or converter name, page path, rating, suggestion text, submission time, browser user agent, and a short one-way hash of the request source. Do not include sensitive personal, financial, medical, legal, or account information in suggestions.
Analytics, AI, and Hosting Providers
Calxo AI uses Vercel Web Analytics for cookieless, anonymized aggregate traffic and calculator-interaction measurement. Interaction events identify the calculator and actions such as use, sharing, printing, CSV download, or copying an embed; they never include values entered into a calculator. Vercel may also process IP addresses, request metadata, error logs, and security events to operate and protect the service. If you accept optional analytics, Google Analytics receives the same path-only page views and input-free interaction events with advertising signals disabled, while Meta Pixel receives page-view events for campaign measurement. Calculator query-string inputs are not included in analytics URLs or events. Feedback may be stored in the configured database or local server storage. AI explanation requests are processed through the configured AI gateway and model provider solely to generate the requested explanation.
Retention
Local preferences stay on your device until you clear browser storage. Analytics consent records stay in local storage for up to 12 months unless you change your choice or clear them sooner. Analytics providers retain aggregate or consented measurement data according to their configured retention settings and privacy terms. Feedback records are retained as long as needed to improve the service unless deletion is requested or a shorter retention period is configured. AI explanation payloads are not stored by Calxo as account records. Hosting, security, and error logs are retained for up to 30 days unless a longer period is required to investigate abuse, security incidents, or legal obligations.
Your Rights
Depending on your location, you may have rights to access, correct, delete, restrict, object to, or port personal data. You may withdraw optional analytics consent at any time through Privacy Choices in the site footer, by clearing local storage, or through browser privacy controls.
