Privacy policy

Last updated 30 August 2026

lemon.fun is a launchpad and trading terminal. We keep the minimum needed to run it, and we do not sell data to anyone.

Website and terminal

When you connect a wallet or trade on the terminal we store:

your public wallet address and the signature that proves you control it
your trades, orders and portfolio history, which are public on chain anyway
trading wallets the platform holds for you, with the private key encrypted at rest and never shown anywhere except your own export flow
basic technical logs such as request time and error text, kept for troubleshooting

We never ask for your seed phrase, and we cannot move funds from a wallet you connect yourself. Every transaction from a connected wallet needs your own approval.

Private key export

The key of a platform held trading wallet can be exported only by you, from your portfolio page, behind a wallet signature and a 3 hour timelock. It is never sent by email, never shown in Telegram and never written to a log.

Telegram trading bot

The bot @tradelemon_bot stores only what it needs to be your account in a chat:

your Telegram user id, chat id and username
your bot settings: buy presets, slippage and priority
the trading wallet it opened for you, and the coins you looked at or traded
a short activity counter used for fair use limits

The bot reads only messages sent to it. It does not read other chats, does not post on your behalf and does not contact your Telegram contacts. If you link the bot to a lemon.fun account with a one time code, the chat and that account become the same trading account.

Third parties

We use infrastructure providers for hosting, the database, blockchain RPC access, market data and chart rendering. They process data only to deliver those services. Public blockchain data is, by design, permanent and outside our control.

Keeping and removing data

Account and trading records are kept while your account exists. To have your account and its data removed, email hello@lemon.fun from the address or Telegram account you use, or send /privacy in the bot for the same instructions. Withdraw any funds from a platform held wallet first, because a deleted wallet record cannot be recovered.
