Privacy Policy

Last updated: August 28, 2026

This Privacy Policy explains what information MarketWall (“we”, “us”, “market-wall.com”) collects when you use this site, how that information is used, and the choices you have about it. By using MarketWall you agree to the collection and use of information as described here.

Information we collect

Account information

If you create an account, we collect your email address and any profile details you provide (such as a display name), plus whatever a third-party sign-in provider (e.g. Google) shares with us when you use it to sign in. We use this to authenticate you, keep your saved preferences (pinned symbols, filters, watchlists) attached to your account, and contact you about your account when necessary.

Usage and analytics data

With your consent (see “Cookies & analytics” below), we collect anonymized/aggregated data about how the site is used — pages visited, features used, approximate location (country/region-level), device and browser type, and similar diagnostic information. This helps us understand what’s working, what’s broken, and where to prioritize improvements. We do not use this data to build an individual advertising profile of you ourselves.

Contact form submissions

If you use the contact form, we store the name, email address, and message you submit so we can respond to you. We keep contact submissions only as long as needed to handle your request and for a reasonable period afterward for our own records.

Cookies & similar technologies

We use a small number of strictly-necessary cookies/local storage entries to keep you signed in and remember basic preferences (such as your light/dark theme choice and your analytics consent decision itself). These are required for the site to function and aren’t part of the consent choice described below.

Cookies & analytics

Google Analytics & Vercel Analytics

We use Google Analytics and Vercel Analytics to understand aggregate site traffic and usage patterns. These only load after you actively accept the analytics cookie banner shown on your first visit — declining, or not responding, means neither script runs and no analytics cookies are set. You can change your decision at any time by clearing your browser’s local storage for this site, which will show the banner again.

Google AdSense

MarketWall displays advertising served by Google AdSense. Google, as a third-party vendor, uses cookies (including the DoubleClick cookie) to serve ads based on your prior visits to this site and other sites on the internet. Google’s use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites. You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors’ use of cookies for personalized advertising by visiting www.aboutads.info.

How we use your information

To provide, operate, and maintain the site and your account.
To respond to support requests and messages sent through the contact form.
To understand aggregate usage and improve the product (only with your analytics consent).
To detect, prevent, and address technical issues, abuse, and fraud.
To comply with legal obligations.

Data sharing

We do not sell your personal information. We share data only with the service providers that help us run the site — for example, our hosting/database provider, our email delivery provider, and (with your consent) Google Analytics and Vercel Analytics — and only to the extent needed for them to perform that service, or when required by law.

Data retention

We keep account data for as long as your account is active. If you delete your account, or ask us to delete your data, we remove or anonymize it within a reasonable period, except where we’re required to keep it longer for legal, security, or accounting reasons.

Your rights

Depending on where you live, you may have the right to access, correct, export, or delete the personal data we hold about you, and to withdraw analytics consent at any time. To exercise any of these rights, or if you have questions about this policy, please reach out through our contact page and we’ll respond as soon as we can.

Children’s privacy

MarketWall is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will delete it.

Changes to this policy

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the “Last updated” date at the top of this page.
