Privacy policy

Last updated 25 October 2026

Tern is a browser extension for trading on axiom.trade from your own Solana wallet. This page sets out what leaves your browser, where it goes, why, and how long it's kept.

In short

• No analytics, no tracking, no ads, no telemetry. We don't sell your data or use it for advertising.
• Your private keys and passphrase are never sent to us or anyone else. They're stored only in your browser, encrypted with your passphrase (Argon2id and AES-GCM).
• The few things that do reach Tern's servers are listed below, with how long they're kept.

What stays in your browser

Your wallets (encrypted), settings, limit orders and the profit and loss of your trades are stored in Chrome on your computer. Removing Tern from Chrome deletes them, so keep a backup of your private keys.

What Tern's servers receive

Tern's servers run on Cloudflare at api.tradetern.xyz and friends.tradetern.xyz.

Your fee rate

When you open Tern and every 2 minutes while you trade, Tern asks api.tradetern.xyz for your wallet's fee rate. The request contains your wallet's public address. We don't record these requests. We only keep a rate for a wallet when we set one ourselves, for example a lower rate for an affiliate's traders.

Coin launches

When you launch a coin, its picture, name, symbol, description and links go to api.tradetern.xyz, which puts them on IPFS through Pinata. IPFS is public, and what's put there can't reliably be taken back. The launching wallet signs the upload, and we count uploads per wallet per day to stop abuse; the count is deleted after 2 days.

Friends (optional)

If you use Friends, friends.tradetern.xyz stores your Friends identity (a key made in your browser), the name you choose, your friend code, your friends and friend requests, and when you were last online.

Messages, and the coin you're viewing, are encrypted in your browser for each friend before they're sent. The server keeps the last 200 messages of each conversation and the latest coin update for each friend, encrypted, and can't read them. It does see who you're friends with, when you're online, and when messages are sent and how long they are. You can stop sharing it by switching off "Show friends the coin you're on" in the Friends box.

Your encrypted backup

Tern backs up your settings, wallet names, which wallets you trade with, your profit and loss, your Friends name and your sharing choice, so they come back when you import your main wallet on another computer. They're encrypted in your browser with a key made from your main wallet's private key, and stored on friends.tradetern.xyz under an ID made from that key one way. We can't read the backup or tell which wallet it belongs to. Other wallets' keys are never in it, even encrypted.

Limits against abuse

Sign-ins, backups and uploads are limited per IP address by Cloudflare's rate limiting, which uses your IP address for about a minute. We don't store IP addresses.

Cloudflare

Cloudflare runs these servers and handles connection data such as IP addresses to deliver requests, under its own privacy policy.

What other services receive

To trade, Tern connects from your browser straight to these services. Like for any Solana wallet, they see your IP address, your wallet addresses and the transactions they handle:

• Solana RPC (PublicNode, or the RPC you set): balances, prices and sending transactions
• Helius Sender and Jito: sending transactions quickly
• Jupiter: quotes and swaps for coins that trade outside pump.fun
• DexScreener: coin prices and details

Solana transactions are public, including Tern's fee, which is paid in the same transaction as each trade.

Tern runs only on axiom.trade. It reads the coin you're viewing from the page so it can trade it, and sends nothing about Axiom to us, apart from the encrypted coin updates to your friends described above.

Your choices

• Friends is optional. If you don't use it, nothing about you is stored there.
• To delete your Friends account (with its friend links and messages), email tradetern@gmail.com with your friend code.
• To delete your encrypted backup, email tradetern@gmail.com. Because we can't tell whose backup is whose, we'll help you find yours from Tern.
• Removing Tern from Chrome deletes everything it stored in your browser.

Other things to know

• Tern is for people 18 and over.
• Tern's use of this data follows the Chrome Web Store User Data Policy, including its Limited Use requirements.
• If this policy changes, the new version goes on this page with a new date, and we post about it in Tern's Discord.
