Privacy Policy

01What we collect

The site collects the following information.

• Your Google account details: when you sign in with Google, your email address, display name and the user ID tied to your Google account
• Your wallet address: the EVM or Solana address you add to receive rewards, and which kind it is
• Your X handle: if you choose to add it. If you post on X to verify it, that post is public on X
• Referral details: your invite code, the code and referrer you signed up with, and whether the referral is complete (whether you have judged and voted for your #1 Pick)
• Registered-member activity: days you visit while signed in, your browser’s pre-sign-in judgement count at registration, and when you first request more predictions. We use these for participation, return and referral reporting and priority launch notifications.
• Your Arena activity: your recorded judgements (the date, the image you chose and the one you didn't) and the image you voted for as your #1 Pick
• Fraud-prevention signals: when you sign in, Google's reCAPTCHA Enterprise (Firebase App Check) collects information about your browser and device
• Analytics: only if you accept cookies, Google Analytics collects the pages you view, what you do on the site, where you came from, your device and browser type, and your approximate region
• Connection details: to deliver the site, our hosting provider processes connection information such as your IP address

02What we keep in your browser

The site stores the following in your browser (localStorage and similar).

• Your language choice
• Your choice about analytics cookies
• The invite code and first visit's UTM source, medium, campaign and term. We save these with your registration for campaign reporting, separately from analytics consent
• Your Arena activity before you sign in (images you judged, your #1 Pick and so on)
• What keeps you signed in (Firebase Authentication)

03How we use it

We use the information to:

• take waitlist sign-ups, keep the waitlist order and confirm who you are
• email you about SAI, such as the launch, beta invites and campaigns
• grant perks and rewards such as Alpha and SAI POINT, and send them to the wallet you added
• run the Arena campaign, count judgements and votes, and announce the results
• work out whether a referral is complete and grant referral perks
• match the X account you added to your work on SAI, and prevent impersonation
• prevent fraud and keep the site secure
• understand how the site is used and improve it and SAI
• answer your questions
• meet our legal obligations

04Cookies and analytics

The site uses Google Analytics and Microsoft Clarity through Google Tag Manager. Both run only if you choose OK on the cookie banner; until you choose, or if you choose Decline, neither runs. We use no advertising cookies and never sell data.

After sign-in, Google Analytics uses an internal user ID. We send no email address, name or wallet address. Microsoft Clarity collects clicks, scrolling and device details for heatmaps and session replay to improve the site. Areas displaying personal information are masked. See Microsoft's privacy statement at https://privacy.microsoft.com/privacystatement .

You can change your choice at any time with the buttons below. For how Google handles this data, see Google's policy (https://policies.google.com/technologies/partner-sites ).

05Service providers and processing outside your country

We use the following providers to run the site, and they handle personal information on our behalf for that purpose.

• Google LLC (United States): Firebase Authentication (sign-in), Cloud Firestore (storing registrations and other data, in a Hong Kong data centre), Firebase App Check and reCAPTCHA Enterprise (fraud prevention), Google Tag Manager and Google Analytics (analytics)
• Microsoft Corporation (United States): Microsoft Clarity (consent-based heatmaps and session replay for usage analysis)
• Cloudflare, Inc. (United States): delivering and securing the site

These providers may handle information in the United States, Hong Kong and other countries, whose data-protection laws may differ from yours. We have checked from their terms and published materials that they take appropriate measures to protect personal information.

06Sharing with others

We don't share your personal information with anyone else without your consent, except:

• where the law requires it
• where it is needed to protect someone's life, body or property and we can't readily get your consent
• with the service providers above, as far as needed for these purposes
• when the business is transferred, for example in a merger

07How long we keep it

We keep personal information for as long as we need it for these purposes. Once we no longer need it, or when you ask us to delete it, we delete it without delay unless the law requires us to keep it.

08How we protect it

To prevent personal information from leaking, being lost or being damaged, we:

• encrypt connections (HTTPS)
• restrict access to the database (you can see and change only your own registration, never anyone else's)
• limit who has administrator access

09Your rights

You can ask us how we use your personal information, for a copy of it, to correct, add to or delete it, to stop using or erase it, to stop sharing it, and for a record of any sharing. Email sai@nexst.io. Once we have confirmed it is you, we will respond without delay as the law requires.

You can change your wallet address and X handle on the site after signing in. To stop our emails, contact us at the same address.
