Privacy Policy

Chainmole for iOS · Last updated 2026-09-05

Draft. Not published. This page is written for the app as it is built today (v0.1.0). It has to be read and approved, and every [bracketed] placeholder filled in, before it is the real policy.

Chainmole (“the app”) is made by ARB LLC (“we”, “us”). This policy says what the app does with data, in plain words.

In short

1. What the app stores on your phone

The app keeps all of this in its own local database on your device:

WhatExample
Wallet addresses you add, and the nicknames you give them 0x4f2a…9c1d, “Main wallet”
Balances of those addresses, by chain and token 1.5 ETH
Transactions of those addresses date, amount, fee, counterparty address
Daily total value of your portfolio $1,234.56
The one setting that is saved: light or dark appearance dark

A wallet address, and a nickname you write next to it, can say something about you. So we treat this as personal data even though we never see it.

We do not receive any of it. It is never uploaded, backed up to us, or shared with us. It lives in the app’s own storage, which iOS keeps private to the app.

Note that iOS may include the app’s data in your iCloud or iTunes device backup, if you have backups turned on. That backup is between you and Apple.

2. What leaves your phone, and where it goes

2.1 Public blockchain nodes and explorers

To show your balances and transactions, the app asks public blockchain services about your addresses. Your wallet address is part of that request, together with your IP address, which every internet request carries.

ServiceUsed forWhat it sees
ethereum-rpc.publicnode.com, base-rpc.publicnode.com, polygon-bor-rpc.publicnode.com, bsc-rpc.publicnode.com, optimism-rpc.publicnode.com (Allnodes) Balances on Ethereum, Base, Polygon, BNB Smart Chain and Optimism Your address, your IP
api.mainnet-beta.solana.com (Solana Foundation) Balances and transactions on Solana Your address, your IP
graphql.mainnet.sui.io (Mysten Labs) Balances and transactions on Sui Your address, your IP
blockstream.info, mempool.space Balances and transactions on Bitcoin Your address, your IP
eth.blockscout.com, base.blockscout.com, polygon.blockscout.com, arbitrum.blockscout.com, explorer.optimism.io (Blockscout) Transaction history on those chains Your address, your IP
api.jup.ag (Jupiter) Names and icons for Solana tokens The token addresses you hold, your IP. Not your wallet address.

These services are not ours. Each has its own privacy policy, and we cannot control what it keeps. This is how the app works: reading a public blockchain means asking somebody who has a copy of it.

Nothing here is a secret in the way a password is. A blockchain is public, and anybody can look up any address on it. What these requests reveal is that this phone, at this IP address, is interested in these addresses.

2.2 Our own API

The app asks our server for the name, symbol, icon and price of tokens.

What we receive: the chain, the list of token ids (contract addresses) it is asking about, and the currency you have chosen. Not your wallet address, and nothing that names you.

Be aware of what that list still says: the tokens asked about are the tokens you hold. We do not know whose they are, or how many of each you hold, but the request does show which tokens some device holds together.

Server logs. Like any web service, ours writes a request log — the time, the URL asked for, and the IP address it came from. We use it to keep the service running and to find abuse. We keep these logs for [30 days] and then they are deleted.

2.3 Token pictures

Token icons are loaded from the address the token master holds, which today is CoinGecko’s image server. Your phone fetches the picture directly, so that server sees your IP address and which icon you asked for.

2.4 Links you tap

Some screens link out of the app:

Once you leave the app, the site or the app you land on decides what it collects.

3. What the app does not do

4. Why we may process data, and on what basis

For people in the EU, the EEA and the UK, our legal basis under the GDPR is:

Data on your phone is not processed by us at all, so no basis is needed for it.

5. Your choices and rights

The strongest control is in the app itself:

Rights under the law. Because we hold no data that identifies you, we usually cannot find “your” data to act on — a request log holds an IP address and nothing that ties it to a person. Where the law gives you a right to access, correct, delete, object to, restrict or port your personal data, write to us at contact@chainmole.com and we will do what we can. If we cannot identify you in our records, we will tell you so.

6. Children

Chainmole is not for children under 13 (or the age your country sets, if it is higher). We do not knowingly collect anything from them.

7. Security

Every request between the app and a server uses HTTPS. Data on your phone is protected by iOS, which keeps an app’s storage private to that app and encrypts it while the device is locked.

No service is perfectly safe. But the worst case here is smaller than usual: we hold no account, no password and no wallet address, so there is no store of them to lose.

8. Changes

We will update this page when the app changes — in particular if we ever add ads, analytics or a paid plan. The date at the top says when it last changed. A change that matters will also be announced in the app or on the App Store listing.
