This Privacy Policy explains how Growthmill Inc., a Delaware corporation ("we", "us", "our"), collects, uses and shares information when you use predictionsmarket.com and related pages, tools and emails (the "Site").
1. Information we collect
| Information | How we get it | Why we use it |
|---|---|---|
| Usage data: pages viewed, clicks, referring site, approximate location, device and browser type | Google Analytics 4 cookies and similar technologies | Understand how the Site is used and improve it |
| Technical data: IP address, request logs | Automatically, from our hosting provider | Operate and secure the Site, prevent abuse |
| Approximate location (country, state or region, city) | From our hosting provider, which derives it from your IP address. If it cannot, we send your IP address to ipapi.co, an IP-location service, to look it up | Show local teams and markets, and decide which cookie notice applies |
| Error reports and page-speed measurements: the page address and the error or timing only | Sent by your browser to our own server | Find and fix problems. These reports carry no cookies or identifiers, and we do not store your IP address with them |
| Outbound clicks on partner links, with tracking tags | When you click a link to a venue or partner. Our server also counts redirects through our /go/ links | Attribute referrals so we can be paid by affiliate partners |
| Affiliate impressions and clicks | The Impact.com tracking script, which runs on the Site for our Gemini affiliate links | Let our affiliate partner credit our referrals |
| Name, email address and message | When you email us or submit the contact form (form submissions are stored in our database) | Respond to you |
We do not knowingly collect sensitive personal information, and we do not collect payment information. If you are one of our staff, signing in to our private admin area records your GitHub username, the time and a short browser description, for security.
2. How we share information
We share information only with service providers that help us run the Site, under terms that limit their use of it:
- Hosting and database providers, to serve the Site and store data.
- Google, for Google Analytics.
- ipapi.co, only when our hosting provider cannot tell us your approximate location.
- Our email provider, to send and receive email.
- Affiliate partners and networks, such as Kalshi, Gemini and Impact.com, which receive click and referral information when you follow a partner link. After you leave our Site, the partner's own privacy policy applies, and partners may set their own cookies.
We may also disclose information to comply with law or legal process, to protect our rights or the safety of others, or as part of a merger, reorganization, dissolution or sale of assets, including a transfer to a successor company. A successor will be bound by this policy for information it receives.
We do not sell personal information, and we do not share it for cross-context behavioral advertising.
3. Cookies
We use these cookies and similar technologies:
- Essential: a small record of your cookie choice, kept in your browser so we don't ask again.
- Analytics: Google Analytics 4 cookies. We have turned off Google Signals and advertising features in Google Analytics, so our analytics data is not used to personalize ads.
- Affiliate tracking: the Impact.com script, which records impressions and clicks on its affiliate links and may set cookies.
If you are in the EU, the EEA, the UK or Switzerland, analytics and the Impact.com script run only after you accept them in our cookie banner. Everywhere else they run by default, and you can opt out. If your browser sends a Global Privacy Control signal, we do not load the Impact.com script. You can change your choice at any time:
You can also block or delete cookies in your browser settings, and you can opt out of Google Analytics with Google's browser add-on. Partner sites you visit through our links may use their own cookies.
4. Retention
Google Analytics keeps user-level analytics data for 14 months. We keep contact form submissions and emails you send us for up to 2 years, unless we need them longer to resolve a dispute or meet a legal obligation. Request logs are kept by our hosting provider under its own retention settings.
5. Your rights and choices
Depending on where you live, including California and Texas, you may have the right to access, correct or delete your personal information, to get a copy of it, and to opt out of its sale or use for targeted advertising (we do neither). To make a request, email [email protected]. We will verify the request and respond within 45 days. We will not discriminate against you for exercising these rights. If we deny your request, you may appeal by replying to our response.
6. Children
The Site is not intended for anyone under 18. We do not knowingly collect personal information from anyone under 18. If we learn we have, we will delete it.
7. Security
We use reasonable administrative and technical measures to protect information, including encrypted connections. No method of transmission or storage is completely secure.
8. Visitors outside the United States
The Site is operated in the United States and information is processed there.
9. Changes
We may update this policy. We will post the updated policy with a new effective date and, for material changes, give notice on the Site.
