Privacy Policy

This policy explains what information DissMarket collects, why we collect it, who we share it with, and the rights you have under U.S. state privacy laws — including the rights to access, correct, delete, and opt out.

1. Who we are

DissMarket is an independent publication that measures the gap between what prediction markets price and what the wider public actually thinks. This privacy policy applies to www.dissmarket.com and the related newsletter, voting product, and data feeds operated by DissMarket LLC, a Wyoming limited liability company ("DissMarket," "we," "us," or "our").

For questions about this policy or your data: privacy@dissmarket.com. For other legal matters: legal@dissmarket.com.

2. Information we collect

We collect only what we need to run the site, the newsletter, and the voting product. We group it into three buckets.

Information you give us

• Newsletter signup. Your email address, and (optionally) your first name. You give us this when you subscribe to the weekly newsletter.
• Voter account. If you create an account to vote, we collect a username, an email address, and a mobile phone number for one-time verification (we use phone verification to discourage bots). If you choose to set a public display name, that name appears on the leaderboard.
• Vote and forecast data. The questions you vote on, the predictions you submit, the time of submission, and how those predictions resolve.
• Communications. If you email us — for press, partnerships, methodology questions, corrections, or legal — we receive your address and the contents of the message.

Information collected automatically

• Server and request logs. When you load a page, our hosting provider (Vercel) records the request: IP address, user-agent, referring URL, the page or asset requested, and a timestamp. These logs are used for security, abuse prevention, debugging, and basic traffic measurement.
• Device and browser data. Information your browser sends with every request — type, version, language, and approximate location inferred from IP address.
• Site interactions. If we use first- or third-party analytics in the future (for example, to count page views or measure which articles people finish reading), we will update this policy and, where required, obtain consent before doing so.

Information from third parties

• Phone verification provider. When you verify a phone number for voting, our verification provider confirms whether the code we sent was entered correctly. We do not receive your carrier billing details.
• Embedded content. When we embed charts, videos, or social posts (for example from X), the platform that hosts that content may receive a request from your browser when the page loads.

We do not knowingly collect government identifiers (Social Security numbers, driver's-license numbers), precise geolocation, biometric data, or financial-account information. Voting is free and there is nothing wagered.

3. How we use information

We use the information described above for the following purposes:

• Operate the service. Show you the site, deliver the newsletter, accept and grade your votes, and keep the leaderboard accurate.
• Authenticate and prevent abuse. Verify your phone number at signup, detect bot and spam activity, enforce our rules, and protect the integrity of the DissMarket Index.
• Compute aggregate signals. Combine vote data across users to produce the public DissMarket Index and related research outputs. Aggregate, de-identified outputs do not identify you personally.
• Communicate with you. Send the weekly newsletter you signed up for, send transactional messages (verification codes, account notices, replies to inquiries), and — only with your consent — send occasional product announcements.
• Improve the product. Understand what works, fix what doesn't, and inform editorial decisions.
• Comply with law and protect rights. Respond to lawful requests, enforce our terms, and defend ourselves and our users against fraud, abuse, and legal claims.

We do not use your personal information to make automated decisions that produce legal or similarly significant effects about you.

4. How we share information

We share personal information only in the limited situations described here.

• Service providers. Vendors that run pieces of our infrastructure under written contracts that limit them to processing data on our behalf. Categories include: hosting and edge delivery (Vercel), email delivery, phone verification, customer-support tooling, and (if used) analytics and error monitoring.
• Editorial and aggregate outputs. Public leaderboard names, calibration scores, and aggregate Index figures may be displayed publicly or licensed to media organizations and researchers. Aggregate figures do not identify individual voters.
• Legal and safety. Where we believe in good faith that disclosure is necessary to comply with law, respond to valid legal process (subpoena, court order), enforce our terms, or protect the rights, property, or safety of DissMarket, our users, or the public.
• Business transfers. If DissMarket is involved in a merger, acquisition, financing, or sale of assets, personal information may be transferred as part of that transaction. We will require the recipient to honor commitments made in this policy or notify you of material changes.
• With your direction or consent. When you ask us to, or when you direct us to share with a third party.

5. Sale and "sharing" of personal information

We do not sell personal information for money, and we do not "share" personal information for cross-context behavioral advertising as those terms are defined under the California Consumer Privacy Act (as amended by the CPRA), the Virginia Consumer Data Protection Act, the Colorado Privacy Act, the Connecticut Data Privacy Act, the Utah Consumer Privacy Act, the Texas Data Privacy and Security Act, the Oregon Consumer Privacy Act, and other comparable U.S. state laws.

We have not knowingly sold or "shared" personal information in the preceding 12 months. If that ever changes, we will update this policy, post a clear "Do Not Sell or Share My Personal Information" link, and honor opt-outs — including the Global Privacy Control browser signal.

We do not engage in profiling that produces legal or similarly significant effects, and we do not sell or share the personal information of consumers we know to be under 16.

6. Cookies and tracking technologies

Today the site uses only what's strictly necessary to display pages and remember basic preferences. We may add additional cookies as the product grows; if we do, we will update this section and, where required by law, ask for your consent first.

• Strictly necessary. Cookies that keep you signed in, remember session state, and protect against abuse. These are required for the site to work.
• Functional. Cookies that remember preferences (for example, dismissing a banner). Optional.
• Analytics. If we add analytics, we will use privacy-respecting tools and keep IP addresses truncated where the vendor supports it.
• Advertising. We do not run third-party behavioral advertising on the site.

Embedded fonts. The site loads typefaces from Google Fonts. When your browser fetches a font file, Google receives the request, including your IP address and user-agent. Google states it does not use these requests to build advertising profiles.

You can block or delete cookies in your browser settings. Some parts of the site (especially anything that requires you to sign in) may not work if you do.

7. How long we keep information

We keep personal information only as long as we need it for the purposes set out above, plus a short tail to satisfy legal, tax, audit, or dispute-resolution obligations. Specific defaults:

• Server logs: typically 30–90 days, then deleted or aggregated.
• Newsletter subscribers: until you unsubscribe, plus a short suppression record so we don't email you again by accident.
• Voter accounts: while your account is active, plus a short period after deletion to prevent re-registration abuse and preserve the integrity of resolved-vote history. Aggregate vote data may be retained indefinitely in de-identified form.
• Support emails: typically up to two years.

8. Security

We use reasonable administrative, technical, and physical safeguards designed to protect personal information against loss, theft, and unauthorized access — including encryption in transit (TLS), access controls, and vendor security review. No system is perfectly secure, and we cannot guarantee that information will never be accessed by unauthorized parties. If we ever experience a breach affecting your personal information, we will notify you and the appropriate authorities as required by law.

9. Your privacy rights

Depending on where you live, you may have some or all of the rights below. We do not discriminate against you for exercising any of these rights — for example, by denying service, charging a different price, or providing a lower quality of service.

Rights for residents of California, Virginia, Colorado, Connecticut, Utah, Texas, Oregon, Montana, Iowa, Indiana, Tennessee, New Hampshire, New Jersey, Delaware, Minnesota, Maryland, and other states with comprehensive privacy laws

• Right to know / access. Request a copy of the personal information we hold about you, the categories of sources, the purposes of processing, and the categories of recipients.
• Right to correct. Ask us to fix inaccurate personal information.
• Right to delete. Ask us to delete personal information we hold about you, subject to legal and operational exceptions (for example, completing a transaction you requested, complying with law, or preserving the integrity of resolved votes already aggregated into the public Index).
• Right to portability. Receive a portable copy of personal information you provided to us, in a machine-readable format.
• Right to opt out of sale or "sharing." As described above, we do not sell or "share" personal information; if that ever changes, you will be able to opt out at any time.
• Right to limit use of sensitive personal information (California). We do not collect or use sensitive personal information for purposes that would trigger this right.
• Right to opt out of profiling that produces legal or similarly significant effects. We do not engage in such profiling.
• Right to appeal (Virginia, Colorado, Connecticut, Texas, Oregon, Montana, and others). If we deny your request, you may appeal that decision by replying to our response or emailing privacy@dissmarket.com with the subject line "Privacy Appeal."

California "Shine the Light"

California Civil Code § 1798.83 gives California residents the right to ask once per year for a list of the personal information categories disclosed to third parties for those third parties' direct marketing purposes. We do not disclose personal information to third parties for their direct marketing purposes.

Nevada

Nevada residents may submit a verified request directing us not to make any covered "sale" of their personal information. As stated above, we do not engage in such sales. You can still submit a request to privacy@dissmarket.com and we will record your preference.

10. How to exercise your rights

Send your request to privacy@dissmarket.com. To help us route the request, please tell us:

• Which right you are exercising (access, correct, delete, port, opt out, appeal).
• The state you reside in.
• Enough information for us to verify that you are the person the data is about — typically the email address you used to sign up, plus confirmation from that email.

We will acknowledge your request promptly and respond within the timeframes required by your state's law (generally 45 days, with a permitted extension where necessary). For sensitive requests we may ask you to verify additional details before we act. There is no fee for a reasonable request; we may charge or decline manifestly unfounded or excessive requests, and we will explain that decision in writing.

Authorized agents. You may use an authorized agent to submit a request on your behalf. We will ask the agent to provide proof of authorization (a signed permission, power of attorney, or proof under California Probate Code) and may contact you directly to confirm.

11. Children's privacy

DissMarket is intended for users 16 and older. We do not knowingly collect personal information from children under 13, and we do not "sell" or "share" the personal information of consumers we know to be under 16. If you believe a child under 13 has provided personal information to us, please email privacy@dissmarket.com and we will delete it promptly.

12. Do Not Track and Global Privacy Control

Most browsers send a "Do Not Track" signal. There is no industry standard for honoring it, and we do not currently respond to DNT signals.

We honor the Global Privacy Control (GPC) browser signal as a valid opt-out request from people residing in states whose laws recognize universal opt-out mechanisms (currently California, Colorado, Connecticut, Oregon, Texas, and a growing list of others). Because we do not sell or "share" personal information today, GPC has no practical effect — but we record the signal so the opt-out remains in force if our practices ever change.

13. International users

DissMarket is operated in the United States. If you access the site from outside the United States, your information will be transferred to, stored in, and processed in the United States, where data-protection laws may differ from those of your jurisdiction. By using the site you understand and agree to that transfer.

14. Changes to this policy

We will update this policy from time to time to reflect changes in our practices, the services we offer, or the law. When we make a material change, we will update the "Last updated" date below and, where appropriate, notify you by email or by posting a notice on the site. Your continued use of DissMarket after the change takes effect means you accept the updated policy.
