The Short Version
The rest of this page gives the details. If something here is unclear, email freeaimathsolver@gmail.com.
Who We Are and How to Contact Us
The website Mathvelo is operated by [OWNER NAME OR COMPANY] in [CITY, COUNTRY]. For the purposes of data protection law, we are the controller of the limited personal data described below.
Questions or requests about privacy: freeaimathsolver@gmail.com.
What We Collect and What We Don’t
We do not ask you to create an account, and we do not ask for your name, email address, phone number or location to use any calculator.
The numbers and expressions you enter are processed inside your browser. They are not sent to our servers, except when you choose an AI feature (see below).
If you email us, we receive your email address and whatever you write. We use it to reply, to look into the problem you report and to keep a record of the conversation. We do not add you to any mailing list.
What Is Stored on Your Device
To make the calculators comfortable to use, the site saves a few things in your browser’s local storage. This stays on your device, and we cannot read it.
| What | Why it is stored |
|---|---|
| ↺Calculation historysc_h, cz_h | So you can reuse earlier results after reloading the page. |
| ⚙Settingssc_set, cz_st, sc_theme | Angle unit, number format, decimal places, calculator model and colour theme. |
| xVariablessc_vars, cz_v | The values you store in A, B, X and other variables. |
| ∑Solver problemsslv_p2, slv_fb | Your list of solved problems and any thumbs-up or thumbs-down you give a solution. |
You can remove all of it at any time by clearing site data in your browser settings, or with the Clear buttons inside the History and Problems panels. This storage is not a cookie and is never used to follow you across other sites.
Hosting and Server Logs
The site is hosted by [HOSTING PROVIDER]. Like almost every web server, the host records technical details of each request, such as the IP address, browser type, the page requested and the time. These logs are used to keep the site running and secure, and are normally kept for [30] days before they are deleted. We do not use them to build profiles of visitors.
Third-Party Services
Google Fonts. The pages load the typefaces Plus Jakarta Sans and JetBrains Mono from Google Fonts. Your browser therefore contacts Google’s servers, which receive your IP address and browser details. Google explains how it handles this in its Google Fonts privacy FAQ.
AI provider. Only when an AI feature is turned on and you use it, as described next.
We do not use advertising networks, social media pixels or analytics tools at the moment. If we add any of them, we will update this policy first and ask for your consent where the law requires it.
Optional AI Features
The step-by-step solver works on its own, inside your browser. Some extras use an AI service: AI solve, Explain simply, Another method, Double-check, follow-up questions and Photo. They are available only when the site has an AI service connected.
When you press one of those buttons, the following is sent to our AI provider, [AI PROVIDER], through a small relay run for this site:
- The problem text you typed, or the photo you chose.
- For explanations and follow-ups, the solution shown on screen and your question.
- The language you picked for the explanation.
Your calculator history, variables and settings are not sent. Because a photo or a typed question can contain personal information, please do not include names, addresses or other private details. The provider handles the data under its own terms and privacy policy, and we do not link requests to a person.
Cookies
The site does not set cookies of its own. The browser storage described above is separate from cookies. If we later add services that use cookies, such as analytics or advertising, we will list them here and show a clear consent choice before they run.
Your Rights and Choices
Depending on where you live, for example in the European Economic Area, the United Kingdom or California, you may have the right to ask what personal data we hold about you, to have it corrected or deleted, to object to or restrict how it is used, and to receive a copy of it.
Because we hold almost no personal data, most requests are quickly answered, but we are happy to help. Email freeaimathsolver@gmail.com. We reply within one month, and we may ask you to confirm it is really you before acting on a request.
Legal bases. Where European or UK law applies, we process server logs on the basis of our legitimate interest in running and securing the site. We process what you send to an AI feature because you ask us to by pressing the button.
California. We do not sell or share personal information as those terms are defined in California law. Do Not Track. The site does not track you, so it behaves the same whether or not your browser sends a Do Not Track signal.
If you are unhappy with how we handled a concern, you have the right to complain to your local data protection authority.
Children’s Privacy
The calculators are used by students, but the site is not directed at children under 13, or under the age set by local law where that is higher, and we do not knowingly collect personal data from them. If you believe a child has sent us personal information, email us and we will delete it.
Security and International Transfers
Pages are served over HTTPS, and nothing you type into a calculator leaves your device unless you use an AI feature. No method of transmission or storage is perfectly secure, but we keep the amount of data we handle small for exactly that reason.
Our host and our AI provider may process data in countries other than your own. Where that happens, they are responsible for protecting it under their own terms and the safeguards that apply to them.
Changes to This Policy
We will update this page when the site changes in a way that affects your privacy, for example when a new third-party service is added. The date at the top shows the latest revision. Significant changes will be announced on the home page.
