Last updated: October 6, 2026. Short version: we keep your wallet address and your coins, nothing else that names you. No accounts, no cookies, no ad trackers.
For every coin: the market, side, amount, the way you paid, your wallet address, the transaction hash, and the wish and name you wrote. For creator wells: the handle, the payout address and its signature. For rate limits, reports and a daily visitor count we keep a keyed hash of your IP address, never the address itself.
Transfers on Polygon and Base are public forever, and anyone can link them to your wallet. On the site, your wish and the name you chose show with your coin. Anonymous hides your name and address on Wishwell only; the transfer itself stays public on-chain.
Local storage keeps receipts of your coins (so My wishes can find anonymous ones), the wallet you used last and your sound setting. Clearing site data removes them. Fonts load from Google Fonts, which sees your IP address when it serves them.
Our server asks Polymarket's public API about markets and public blockchain nodes about transfers; your wallet address goes to those nodes when we check balances and payments. Reported wishes are forwarded to our moderator on Telegram. We don't sell or share data with advertisers.
Ask @crowdfan_bot on Telegram to hide a wish or name, or to delete what we hold about your wallet. On-chain transfers can't be deleted by anyone.
