Privacy Policy

Last updated: October 5, 2026

This policy explains what information Martingale Tracker (“we”, “us”), available at trackermtg.com, collects when you use the website and the app, how we use it, and the choices you have.

1. Using the app without an account

You can use the calculator without creating an account. The numbers you type (capital, number of trades, target) stay in your browser while you use the page. We do not send them to our servers.

2. Information we collect when you create an account

An account is only needed for the trading journal (calendar). When you create one, we collect:

• Your first name and last name
• Your email address
• Your password. It is stored in encrypted (hashed) form, and we never see it.
• The journal entries you choose to save: a date and an amount (profit or loss)

We use this information only to create your account, let you sign in, show your journal, and contact you about your account (for example, email confirmation or password reset).

3. Analytics

We use Vercel Web Analytics to count visits and understand how the site is used. It records information such as the pages visited, the referring site, the country, and the type of browser and device. Vercel Web Analytics does not use cookies, and we do not use it to identify you personally.

4. Advertising and cookies

We use, or may use, Google AdSense to show ads on this website. Google and its partners may use cookies and similar technologies to show ads based on your visits to this site and to other websites.

• Google’s use of advertising cookies lets it and its partners show ads based on your visits to this and other sites on the internet.
• You can turn off personalized advertising in Google Ads Settings, or visit www.aboutads.info to opt out of some third-party advertising cookies.
• To learn more, see how Google uses information from sites that use its services.

If you visit from the European Economic Area, the United Kingdom or Switzerland, we will ask for your consent before personalized ads or advertising cookies are used.

When you sign in, the app also stores a login token in your browser’s local storage so you stay signed in. It is removed when you sign out.

5. Service providers

We rely on the following providers to run the service. They process data on our behalf:

• Vercel: website hosting and analytics
• Supabase: accounts, sign-in and journal storage
• Google: advertising (AdSense)

We do not sell your personal information.

6. How long we keep your data

We keep your account information and journal entries for as long as your account exists. You can delete individual journal entries in the app at any time. To delete your account and all of its data, email us at the address below, and we will delete it within 30 days.

7. Your rights

Depending on where you live, you may have the right to access, correct, delete or export your personal information, and to object to some uses of it. To make a request, contact us at contact@trackermtg.com.

8. Security

Your connection to the site is encrypted (HTTPS). Each account can only read and change its own journal. No system is 100% secure, but we take reasonable steps to protect your information.

9. Children

Martingale Tracker is not intended for anyone under 18. We do not knowingly collect information from children.

10. Changes to this policy

We may update this policy from time to time. When we do, we will change the “Last updated” date at the top of this page.
