How to track crypto on a Mac without connecting any account
Watching prices requires no account access whatsoever, because market data is public. Access is only needed if you want software to calculate your holdings automatically instead of you entering the amounts. That’s a convenience, and it’s worth understanding exactly what each level of access exposes before trading privacy for it, since the levels differ enormously and get presented as if they’re similar.
Key takeaways
- Price data is public, so a watchlist or ticker needs no exchange account, wallet address, or API key of any kind.
- A read-only API key cannot move funds but does expose your balances and full transaction history to whoever holds it.
- No legitimate tracking app ever needs a seed phrase or private key, and any request for one should be treated as theft.
- A wallet address is already public on-chain, but sharing it links that address to you in a company’s records, which is a separate exposure.
- Manual entry in local software gives up automation and exposes nothing, which is a reasonable trade for portfolios that change rarely.
The four levels of access, from none to total
These get discussed as one topic. They’re not remotely equivalent, and the differences are what should drive the decision.
| Level | What you provide | What it exposes | Can funds move? |
|---|---|---|---|
| None | Nothing | Nothing about you | No |
| Manual entry | Amounts you type in | Your holdings, to that app only | No |
| Wallet address | A public address | That address’s on-chain history, linked to you | No |
| Read-only API key | Exchange credentials with read permission | Balances, trade history, sometimes more | No, if scoped correctly |
| Trade-enabled API key | Exchange credentials with trade permission | Everything above, plus execution ability | Yes |
| Seed phrase or private key | Full wallet control | Everything | Yes, irreversibly |
The last row exists only to say this: never. There is no tracking feature that requires it, and any app asking is trying to take your funds. This isn’t a caution about choosing carefully. It’s an absolute.
What you get with no access at all
More than people expect, and for many purposes it’s everything they actually wanted.
Public market data covers current prices for essentially any traded asset, percentage changes, historical charts, and market capitalisation. None of it requires knowing who you are. A watchlist of assets you care about is just a list of names stored locally.
What you don’t get is your position value calculated automatically. The app knows Bitcoin’s price; it doesn’t know how much you hold unless you tell it.
For a lot of people that gap is smaller than it sounds. If your holdings change rarely, multiplying a price by an amount you already know is not a meaningful burden, and it’s the entire cost of exposing nothing.
Manual entry, the underrated middle
Typing your amounts into a local app or spreadsheet gets you portfolio value without granting anyone access to anything.
The tradeoff is real: you update it after every transaction, and if you trade frequently that becomes tedious enough to abandon. For a portfolio that changes a few times a year, it’s a few minutes annually.
One thing worth checking before assuming this is private: whether the app stores your entries locally or syncs them to a server. “Manual entry” and “local storage” are separate properties, and an app can offer the first while doing the second. If the entries sync, you’ve told a company your holdings without going through an exchange.
Wallet addresses: already public, still a disclosure
A common misconception runs in both directions here.
On a public blockchain, an address and every transaction it has made are visible to anyone who looks. Providing it to a tracker doesn’t reveal anything that wasn’t already published, which is why address-based tracking is genuinely lower risk than API keys.
But there’s a second exposure people miss. The blockchain shows that an address holds certain assets. It doesn’t show that the address belongs to you. Handing it to a service creates that link in their records, alongside whatever else they know: your email, your IP, your other addresses. Aggregation is the risk, not the balance itself.
Whether that matters depends on your situation and is a reasonable thing to weigh either way. It’s worth weighing consciously rather than assuming “it’s public anyway” settles it.
API keys: read-only is not risk-free
This is where the most consequential decision sits, and where marketing tends to be reassuring in a way the details don’t fully support.
A read-only key scoped correctly cannot place trades or withdraw. That’s a genuine and important limit. But it does expose your complete balance and trading history to whoever holds it, and that information has value independent of whether funds can move: it identifies you as someone worth targeting, and it’s exactly what makes a convincing phishing attempt possible.
If you decide the automation is worth it, several practices reduce exposure:
- Create a key scoped to read-only. Never enable trading or withdrawal permissions for a tracking tool, which has no use for either.
- Use IP allowlisting if your exchange supports it, so the key only works from expected addresses.
- Use a separate key per service so one can be revoked without disrupting others.
- Note the creation date and revoke keys for services you’ve stopped using. Old keys outliving their purpose are a common and avoidable exposure.
- Check what the app does with the key. Stored locally on your Mac is different from stored on the developer’s server, and the difference is the entire security model.
Point five is the one to ask about directly. If an app can’t clearly answer where your key lives, that’s an answer.
Questions worth asking any tracking app
- Does it require an account to function, and does the stated function actually need one?
- Where is data stored: on your machine, or on a server?
- Does it ask for more access than its features require? A price display requesting exchange credentials is a mismatch.
- Is there a published privacy policy naming what’s collected?
- Can you use it fully without providing anything?
The general principle: an app should request the minimum access its actual features need. Requests beyond that deserve an explanation. The same scepticism applies to macOS permissions at install time, covered in our guide to what the Gatekeeper warning actually means.
Where CoinNotch sits, and what it can’t do
CoinNotch operates at the no-access level. It displays public market data in the menu bar and does not trade, hold funds, or connect to any account. There is no login, no API key field, and no wallet connection, because a price ticker doesn’t need any of those to show a price.
The honest limitation follows directly from that design: it cannot show your portfolio value, because it has no way to know what you hold. If automatic position tracking is what you’re after, this is the wrong tool and a portfolio tracker with exchange integration is the right category, with the tradeoffs described above accepted deliberately rather than by default.
The CoinNotch app is useful for the narrower job of knowing where a market sits. Whether that’s sufficient depends on whether you were reaching for a portfolio tool or a price display, and those get conflated more often than they should.
Frequently asked questions
Can I track crypto without connecting my exchange account?
Yes. A price watchlist requires no account access at all, since public market data is available without authentication. You only need to grant access if you want an app to calculate your holdings automatically rather than you entering amounts yourself.
Is a read-only API key safe to share with an app?
Safer than a trade-enabled key, but not risk-free. A read-only key still exposes your balances and transaction history to whoever holds it, and that data is valuable to attackers even though it cannot move funds directly.
Should I ever give an app my seed phrase or private key?
No. No legitimate tracking application needs a seed phrase or private key, because those grant full control of funds rather than read access. Any app requesting them should be treated as an attempt to steal, without exception.
Does sharing a wallet address reveal my holdings?
On a public blockchain, an address and its full transaction history are already visible to anyone who knows the address. Sharing it with an app does not expose new information, but it does link that address to you in that company’s records.
What is the most private way to track a portfolio?
Entering holdings manually in a local spreadsheet or app that stores data on your own machine, combined with a price source that needs no account. This gives up automation in exchange for exposing nothing to a third party.
Do menu bar price tickers need account access?
No. Displaying a market price uses public data, so a ticker needs only a network connection. An app that shows prices but requests exchange credentials is asking for more than its stated function requires.
Deciding for yourself
The question isn’t whether to be private. It’s what automation is worth to you, given what it costs.
Trading frequently across several venues makes manual tracking genuinely impractical, and a read-only key with sensible scoping is a defensible trade. Holding a few assets you rarely move makes the automation nearly worthless, and granting access buys convenience you won’t notice while creating exposure that persists.
Most people default to connecting everything because the interface asks and it’s one click. The useful habit is pausing at that click and asking what it’s actually buying. For related reading, see why menu bar prices don’t match the exchange and where a price should live on your Mac.
