The short version. Your wallet address is your account — there is no email, no password, and no profile to fill in. We store the social activity you create here (who you follow, challenges you send and accept). We never hold your funds or keys, we don't run analytics or advertising trackers, and we don't set cookies.
sidebet is an independent project operated by an individual, not a registered company. It is not affiliated with, endorsed by, or operated by Polymarket.
Questions about this policy or your data: info@sidebet.cash
Only what the features you use actually require. Nothing here is bought from or sold to third parties.
| Data | Why | When |
|---|---|---|
| Wallet address | It is your account identifier — it's how sign-in, your squad, and your challenge history work | When you sign in |
| Display name & avatar | Shown on your challenges. Read from your public Polymarket profile if one exists for your address; otherwise it's just a shortened address | When you sign in |
| Who you follow | To build your squad feed | When you follow someone |
| Challenges | The market, side, amount, and both parties — this is the core feature | When you create or accept one |
| Notifications | So you see what happened while you were away | Generated by challenge activity |
| Plus payment record | Transaction hash and date, to verify your subscription on-chain | Only if you buy Plus |
| Telegram chat ID | To send you notifications there | Only if you link Telegram |
| Discord webhook URL | To post notifications to your channel | Only if you link Discord |
| Session token | Keeps you signed in. Expires automatically and is then deleted | When you sign in |
Signing in means signing a message with your wallet to prove you control the address. It is free, sends no transaction, and grants us no permission to move anything. We never see or ask for your private key or recovery phrase, and no legitimate service ever will.
These live in your browser's local storage on your own device — not on our servers. Clearing your browser data removes them.
sidebet:session — your signed-in address and display namesidebet:apitoken — your session tokensidebet:squad — the traders you followsidebet:plus — your Plus payment receipt, so it survives a refreshsidebet:agegate — remembers you confirmed the age/eligibility noticeAll market data is fetched through our own server rather than directly from your browser. A practical privacy consequence: Polymarket sees our server, not your IP address or which markets you personally browse. If you click through to trade on polymarket.com, you are then on their site under their privacy policy.
Your wallet balances are read directly from public Polygon nodes by your browser. Those providers can therefore see your IP address alongside the wallet address being queried. This is normal for any wallet-connected site, but it is the one place your IP and address meet a third party.
Card and Apple Pay purchases are handled entirely by MoonPay on their own hosted checkout. They collect your payment and identity details directly — we never see your card number or identity documents. We pass them only the destination wallet address and the amount. Their privacy policy governs that transaction.
WalletConnect (if you connect that way), Telegram and Discord (only if you link them) each receive the minimum needed to work, under their own policies.
The site is hosted on Vercel and the backend runs on Fly.io in Toronto, Canada. Both process traffic on our behalf as service providers.
Plus subscriptions are paid as a normal USDC transfer on Polygon. Public blockchains are permanent and world-readable: the payment, both addresses, the amount, and the time are visible to anyone forever, and neither we nor anyone else can delete or reverse them. This is inherent to how blockchains work, not a choice we made.
You can unlink Telegram or Discord at any time in the app, which deletes that link immediately, and signing out clears everything stored in your browser. To have your account and its server-side data deleted, email info@sidebet.cash from any address and include your wallet address. Two things are worth knowing about deletion generally: on-chain payments cannot be erased by anyone, and a challenge necessarily involves another person whose record of it also exists.
sidebet is for adults only — 18+, or 21+ where required locally. It is not directed at children and we do not knowingly collect their data.
If this policy changes materially, the date at the top will change. sidebet is actively being built, so expect this to be revised as features land.
