LION privacy policy
Last updated: 21 October 2026
LION (full name LIFION) is a browser extension. It compares the swap you are about to make on Uniswap, GMGN, Sushi, PancakeSwap, Four.meme, Flap and Pons with LI.FI’s best route, and lets you swap through LI.FI with your own wallet.
LION has no servers of its own, no accounts, no analytics and no ads. It does not sell or share your data, and it sends nothing to its developer. What it handles stays in your browser, or goes straight from your browser to the services that make a quote or a swap possible.
What LION reads
- On the seven supported sites (app.uniswap.org, gmgn.ai, www.sushi.com, pancakeswap.finance, four.meme, flap.sh, ponsfamily.com): the tokens, chains and amount in the site’s trade form, the site’s own quote, and, on the launchpads, what the site says a token is priced in. That is all it needs to compare.
- On any other website: nothing, unless you open LION’s popup there. Then it reads the tab’s address, and starts LION’s swap helper in that tab so your wallet in the page can sign.
- From your wallet: your public wallet address: when you connect the wallet in LION, or, without a prompt, when that wallet has already given the site you are on access to it (wallets answer that read without asking). LION never sees your private keys or recovery phrase. Every approval and every swap is shown in your wallet, and nothing is sent until you confirm it there.
What LION sends, and to whom
- LI.FI (li.quest), for quotes, route lists, token lists, the swap transaction and the swap’s status: the tokens, chains, amount and slippage, your wallet address (a placeholder address before you connect), LION’s integrator name and fee, and, to follow a swap, its transaction hash. LI.FI’s own privacy policy covers that data: li.fi/legal/privacy-policy.
- Public blockchain RPC endpoints (the ones LI.FI lists for each chain, or ones you set in LION): read-only requests such as balances, token allowances, token details and transaction receipts.
- Token and chain logos on the Swap page, loaded from the image addresses in LI.FI’s token and chain lists.
- Your wallet: the approval or swap transaction, for you to confirm.
These requests go out from your browser, so the services that answer them see your IP address, as with any request a web page makes.
What LION stores
- In your browser’s extension storage: your settings (which sites are on, slippage, how token approvals are made, language, whether the card starts folded, an optional LI.FI API key, optional RPC addresses, the wallet you chose for each site and for the Swap page) and the last pair you used on the Swap page.
- For a swap in progress: its details and progress, in session storage, so a page reload does not lose track of it. Chrome clears session storage when the browser closes or the extension updates.
None of this leaves your browser. “Restore defaults” in LION’s settings resets the settings and forgets the wallets; removing the extension deletes everything it stored.
Your own LI.FI API key
If you enter one in LION’s settings, it is stored in your browser and sent only to the API address set in LION, as the x-lifi-api-key header.
Chrome Web Store user data policy
LION’s use of information complies with the Chrome Web Store User Data Policy, including the Limited Use requirements.
Children
LION is not meant for children under 13.
Changes
When this policy changes, the date at the top changes with it, and a change in what LION handles is noted in the extension’s release notes.

LION 隐私政策
最后更新：2026 年 10 月 21 日
LION（全称 LIFION）是一个浏览器扩展。你在 Uniswap、GMGN、Sushi、PancakeSwap、Four.meme、Flap、Pons 上准备兑换时，它把这笔兑换和 LI.FI 的最优路由做比较，并让你用自己的钱包通过 LI.FI 成交。
LION 没有自己的服务器，没有账户，不做统计分析，也没有广告。它不出售、不分享你的数据，也不向开发者发送任何东西。它处理的数据要么留在你的浏览器里，要么从你的浏览器直接发给完成报价或成交所必需的服务。
LION 读取什么
- 在 7 个支持的站点上（app.uniswap.org、gmgn.ai、www.sushi.com、pancakeswap.finance、four.meme、flap.sh、ponsfamily.com）：页面交易表单里的币种、链和数量，页面自己的报价；在发射台上，还有页面写明的代币计价币。比价只需要这些。
- 在其它网站上：什么都不读，除非你在那里打开 LION 的弹窗。打开时它读取这个标签页的网址，并在这个标签页里启动 LION 的交易助手，好让页面里的钱包签名。
- 从你的钱包：你的公开钱包地址：在你于 LION 里连接钱包时读取；如果这个钱包之前已经授权过你所在的网站，LION 也会不弹窗直接读到它（钱包对这种读取不会询问）。LION 永远接触不到你的私钥或助记词。每一次授权和每一笔兑换都会在你的钱包里显示，你在钱包里确认之前，什么都不会发出。
LION 发送什么、发给谁
- LI.FI（li.quest），用于报价、路由列表、代币列表、生成交易和查询交易状态：币种、链、数量和滑点，你的钱包地址（连接钱包之前用一个占位地址）、LION 的 integrator 名称和费率，以及跟踪一笔兑换时它的交易哈希。这些数据适用 LI.FI 自己的隐私政策：li.fi/legal/privacy-policy。
- 公共区块链 RPC 节点（LI.FI 为每条链列出的节点，或你在 LION 里设置的节点）：只读请求，例如余额、代币授权额度、代币信息和交易回执。
- 代币和链的图标：交易页按 LI.FI 代币列表和链列表里的图片地址加载这些图标。
- 你的钱包：需要你确认的授权交易或兑换交易。
这些请求都从你的浏览器发出，所以应答的服务会看到你的 IP 地址，和任何网页发出的请求一样。
LION 保存什么
- 浏览器的扩展存储里：你的设置（启用哪些站点、滑点、代币授权方式、语言、卡片是否默认折叠、可选的 LI.FI API key、可选的 RPC 地址、你为每个站点和交易页选择的钱包），以及交易页上次使用的币对。
- 进行中的兑换：它的详情和进度，保存在会话存储里，这样刷新页面也不会丢失进度。浏览器关闭或扩展更新时，Chrome 会清空会话存储。
这些都不会离开你的浏览器。LION 设置里的「恢复默认」会重置设置并忘掉选过的钱包；移除扩展会删除它保存的一切。
你自己的 LI.FI API key
如果你在 LION 的设置里填写了，它保存在你的浏览器里，只作为 x-lifi-api-key 请求头发给 LION 里设置的 API 地址。
Chrome 应用商店用户数据政策
LION 对信息的使用遵守 Chrome 应用商店用户数据政策，包括其中的“有限使用”要求。
儿童
LION 不面向 13 岁以下的儿童。

本政策变更时，顶部的日期随之更新；LION 处理的数据如有变化，会写在扩展的更新说明里。
