Privacy Policy
Last updated: October 23, 2026
This policy explains what data EveryCalc collects, why, who receives it, how long we keep it, and the controls you have. It covers three things: the EveryCalc website (everycalc.xyz), the EveryCalc tools offered inside ChatGPT and other AI assistants, and the EveryCalc API. EveryCalc does not require an account and does not sell personal data.
Calculator inputs on our website stay on your device
Every calculator on the EveryCalc website runs entirely in your web browser using JavaScript. The numbers you type into a website calculator, home prices, incomes, loan amounts, are processed locally on your device and are never transmitted to our servers, stored, or shared. We cannot see them because they never reach us.
Calculator inputs in our ChatGPT tools and API
When you use an EveryCalc tool inside ChatGPT or another AI assistant, or call our API, the calculation works differently, because the math runs on our server:
- Inputs we receive: the values needed for the calculation that you ask the assistant to run, such as a loan amount, interest rate, term, income, or savings balance. We receive only the parameters in the tool call. We do not receive your ChatGPT account details, your conversation history, or any other part of your chat.
- What we do with them: our server uses the values once, to compute and return your result. The values are processed to answer that single request and are not kept as a record tied to you after the response is returned.
- Outputs: the tool returns the calculation result, the assumptions behind it, and a link to the matching calculator on our website with your inputs prefilled in the link. If you open that link, the values in it travel to our website as part of the page address, the same as typing them into the calculator yourself, and the calculation then runs in your browser as described above.
- What we never do: we do not use tool inputs to build a profile of you, to advertise to you, or for any purpose other than returning your calculation and the aggregate statistics described below.
Technical and usage data we collect
- Server and security logs: our hosting provider processes standard technical data for each request to our website, tools, and API, such as IP address, time of request, the page or tool requested, response status, and browser or client type. This is used to keep the service secure, prevent abuse, and fix faults.
- Aggregate usage statistics: we count usage in anonymous, aggregate form, such as how many times a calculator, tool, or page was used, and total pageview and outbound-link click counts. Where calculation inputs inform these statistics at all, they are recorded only as rounded ranges in aggregate, never as a record about an individual. These statistics tell us which calculators are useful so we can improve them.
- Email: if you write to us, we keep your message and address so we can reply and handle your request.
Cookies and advertising on our website
We work with third-party advertising partners to display ads on our website, which helps keep our calculators free. Our advertising partners and their vendors may use cookies to serve ads based on your prior visits to this and other sites.
- Third-party vendors' use of advertising cookies enables them to serve ads based on your visit to our site and/or other sites on the Internet.
- You may opt out of personalized advertising by visiting your ad settings with the relevant provider, or opt out of many third-party vendors' use of cookies for personalized advertising at aboutads.info/choices.
Our advertising partners maintain their own privacy policies describing how they collect and use data from partner sites; the partner serving an ad on this site is identified in that ad's attribution or settings menu. No advertising cookies are set by our ChatGPT tools or API.
Who receives data
- Cloudflare, our hosting and security provider, processes technical request data on our behalf to deliver and protect the website, tools, and API.
- The AI platform you use (for example OpenAI's ChatGPT) sends us the tool-call parameters you approved and receives the result. Anything you type into that platform outside the tool call is handled by that platform under its own privacy policy, not this one.
- Advertising partners, on our website only, as described in the cookies section above.
- Authorities, only if we are legally required to disclose data.
We do not sell personal data, and we do not share it with third parties for their own marketing.
How long we keep data
- Tool and API inputs: processed to return your result and not retained afterwards as a record about you.
- Aggregate usage statistics: kept indefinitely in anonymous, aggregate form, because they cannot identify anyone.
- Server and security logs: kept only as long as needed for security, abuse prevention, and operations, then deleted or anonymized.
- Email you send us: kept as long as needed to handle your request, then deleted.
Your controls
- You choose what to calculate. If you do not want values processed by our server, use the calculators on our website instead of the AI tools; website calculators never send your inputs anywhere.
- You control cookies through your browser settings and the advertising opt-outs linked above.
- You may email us at hello@everycalc.xyz to ask what personal data, if any, we hold about you, and to request its deletion. Because tool inputs are not retained and usage statistics are anonymous, in most cases there will be no personal data to provide or delete. We respond to requests within 30 days.
Children's privacy
EveryCalc is a general-audience service not directed at children under 13, and we do not knowingly collect personal information from children.
Data security
All traffic to our website, tools, and API is encrypted in transit (HTTPS). Access to our systems and statistics is restricted to the people who operate EveryCalc.
Changes to this policy
We may update this policy from time to time. Material changes will be reflected in the "Last updated" date above.
