Our basic principle
We collect as little personal information as we can, we don't sell it, and we use the tools on this site — like our calculators — without requiring an account. This policy explains the limited data involved when you visit.
What we collect, why, and for how long
Here is the whole picture in one place:
| Data | Why we have it | How long we keep it |
|---|---|---|
| Newsletter email | To send you the newsletter you asked for | Until you unsubscribe |
| Aggregate analytics | To understand traffic and improve the site | Aggregated; not tied to your identity |
| Server logs | Security, reliability and abuse prevention | A short rolling period |
| Cookies / local storage | Remember preferences such as light/dark theme | Until you clear them in your browser |
More detail on the small set of cookies and similar storage we use is in our cookie policy.
Our calculators
The numbers you type into our tools are processed in your own browser to show a result. We don't need an account and we don't store your calculator inputs on our servers.
Third parties
We display market data from third-party providers (named in our methodology) and may use an email provider to deliver the newsletter and an analytics provider as described above. These parties process data under their own terms. We may also link to external sites, whose privacy practices are their own.
How we use information
- To operate, secure and improve the website.
- To send the newsletter to people who asked for it.
- To respond to messages you send us.
We do not sell your personal information, and we don't use it to give you personalised investment advice (we don't give investment advice at all — see our disclaimer).
Your rights & choices
- Unsubscribe from the newsletter at any time using the link in any email.
- Control or block cookies in your browser settings.
- Depending on where you live (for example, under GDPR or CCPA), you may have rights to access, correct or delete personal data we hold about you. To make a request, email us.
Retention & security
We keep personal data only as long as needed for the purpose it was collected, and we take reasonable measures to protect it. No website can promise perfect security, but we work to keep what little we hold safe.
Children
Market Capitalize is intended for adults and is not directed at children under 16. We do not knowingly collect their data.
Frequently asked questions
Do I need an account to use the tools?
No. Every calculator runs in your own browser, with no sign-up and no login. We do not store the numbers you type in.
Do you sell my personal data?
No. We do not sell your personal information, and we aim to avoid tools that build cross-site advertising profiles. We collect as little as we can in the first place.
How do I access or delete data you hold about me?
Depending on where you live — for example under GDPR or CCPA — you can ask us to access, correct or delete your personal data. Email legal@marketcapitalize.com and we will handle it.

We may update this policy and will revise the date above when we do. Questions or privacy requests: legal@marketcapitalize.com.
