KALTHERA
Privacy Notice
Last updated: 12 September 2026
Information we collect
When you enter the Census, Kalthera stores the X handle or profile URL and EVM wallet address you manually submit. We also store campaign answers and progress, XP, Record results, and any public X post URL you later submit for bonus review.
How we use it
We use the submitted handle and wallet to label your Kalthera Record, preserve quest progress in this browser, review optional public post proof, and administer campaign eligibility. This does not sign in to or verify X, and Kalthera cannot post, like, follow, or send messages on your behalf.
Verification limits
A submitted X handle is not proof that you control the X account, and a submitted wallet address is not proof that you control the wallet. Wallet ownership should not be treated as verified until signature verification is enabled. Optional post URLs are reviewed before bonus XP is awarded.
Storage and retention
Campaign data is stored using Supabase, while the website is delivered through Kalthera’s hosting infrastructure. A random, private access cookie reconnects this browser to its saved Record; clearing browser data or changing devices may remove that access. Data is retained while reasonably needed for campaign and project records.
How we protect it
Kalthera limits campaign requests, restricts database access by role, keeps privileged credentials on the server, and uses encrypted HTTPS connections. No internet service can promise absolute security, so only submit information required for the campaign. Kalthera will never ask for your seed phrase or private key.
Sharing
Kalthera does not sell personal data. Access is limited to Kalthera administrators and infrastructure providers needed to operate the website. This flow does not call X’s API or send your Record image, campaign answers, wallet address, or submitted handle to X.
Your choices
The Profile dashboard is temporarily unavailable. You can contact Kalthera to request access, correction, or deletion of submitted campaign data.
Questions
For questions about this notice, contact Kalthera through @Kaltheraxyz on X.
