Which Permissions Should a Crypto App Actually Need?

Published 14 August 2026 · 7 min read

What a price and alert app legitimately needs

Notifications, so it can deliver alerts. Network access, so it can reach its servers. That is essentially the complete list. It does not need contacts, SMS, call logs, location, file access, or accessibility services.

Accessibility permission deserves particular suspicion. It allows an app to read screen content and interact on your behalf — legitimate for assistive tools and a well-documented vector for credential theft in anything financial.

What a portfolio tracker needs

Public wallet addresses, which are safe to share by design and cannot authorise anything. If it connects to exchanges, read-only API keys with withdrawal permission explicitly disabled — most exchanges let you set this when creating the key, and you should.

No tracker requires withdrawal rights. If one asks, the request itself is the answer.

The absolute lines

No app of any kind needs your recovery phrase or private key. Not for verification, not to sync, not to restore, not to claim anything. This rule has no legitimate exception, which is what makes it useful — you never have to evaluate the story attached to the request.

And check permissions after updates. An app that adds a permission in a later version is worth re-examining, because the version you vetted is not the version now running.

A workable method, step by step

The following is deliberately mechanical — that is the point. First, write down what you are trying to find out. "I want to know if Bitcoin breaks its range" is a question you can act on; "I want to keep an eye on the market" is not, and it is why most people end up watching charts aimlessly.

Second, define the specific condition that answers it — a price, a percentage move over a window, or a level relative to a moving average. Third, decide in advance what you will do when that condition is met. Skipping this step is the reason so many alerts fire and produce nothing but a raised heart rate.

Fourth, automate the watching. Set the alert and close the app. Fifth, review monthly: which alerts fired, what did you do, and was it right? Alerts you never acted on should be deleted. The review is what turns app permissions from a one-off setup into a system that improves.

Timeframes: why the same signal means different things

The same chart tells four different stories depending on the timeframe you open it on. A 5-minute chart is dominated by noise, execution and short-term liquidity. A daily chart shows genuine supply and demand. A weekly chart shows the trend that actually determines multi-year outcomes. None is more correct — but mixing them is how people end up taking a long-term position and managing it on a 15-minute chart.

Match the timeframe to your holding period. If you expect to hold for years, intraday movement is not information you should be acting on, and watching it will only cost you the position. If you are trading a multi-day move, the weekly trend is context rather than a trigger.

A useful convention: use the higher timeframe to decide direction and whether to be involved at all, and the lower one only to choose an entry once that decision is made. Alerts fit this naturally — set them on levels that matter on the higher timeframe, and you stop needing to watch the lower one.

Turning this into something automatic

A process that requires vigilance is a process with a known expiry date. You will be asleep, in a meeting, on a flight, or simply not thinking about markets on the day it matters. That is not a discipline failure — it is the normal condition of having a life, and any system that ignores it is badly designed.

So convert every conclusion from this article into a condition that can be watched for you. A level you would act on becomes a price alert. A move size that would change your view becomes a percentage alert. A whole segment of the market you cannot follow coin by coin becomes one bulk rule that scans it and tells you when something unusual happens.

Set them, then close the app. The point of app permissions is not to make you watch more closely — it is to let you stop watching entirely and still be there when it counts. CoinPriceAlert sends push notifications for crypto, stocks, metals and forex, with quiet hours so nothing wakes you at 4am for a move you would not have traded anyway.

Costs that quietly eat the return

Frictions are small individually and substantial cumulatively. Between the chart and your account sit trading fees, the spread between bid and ask, slippage on anything larger than a small order, network fees when moving assets, and conversion costs if you are not trading in your home currency.

None is large in isolation. Together, on an actively traded account, they routinely consume a meaningful share of gross returns — and unlike market moves, they are guaranteed. This is the strongest practical argument for trading less: every round trip you avoid is a cost you certainly save, against a gain you only might have made.

Slippage deserves particular attention because it is worst exactly when you most want to act. Liquidity thins during violent moves, so the market order you place during a crash fills materially worse than the screen suggested. Limit orders paired with alerts are the standard answer: the alert tells you the level arrived, the limit order controls what you pay for it.

The mistakes that cost the most

Setting thresholds too tight. This is the single most common failure, and it destroys the value of the whole system: alerts that fire constantly train you to dismiss them, so the important one arrives already ignored.

Reacting to a move without checking what caused it. A fall that happens while the whole market falls is a different event from a fall that happens alone, and the correct response differs completely. Checking correlation first takes ten seconds and prevents most panic decisions.

Changing the plan mid-move. The level you chose while calm is better than the one you will choose while watching a candle. If you find yourself widening a stop or moving a target during volatility, that is the moment to close the app rather than the moment to act.

Never reviewing. Most people set up app permissions once and never look at whether it worked. A short monthly review — what fired, what you did, what you would change — compounds faster than any refinement of the setup itself.

Risk, defined properly

Risk is not volatility, though the two are constantly conflated. Volatility is how much a price moves. Risk is the probability of a permanent loss of capital — of the reason you owned something ceasing to be true. An asset can be extremely volatile and low-risk for a patient holder, or barely move and be extremely risky if it is quietly failing.

The practical difference: volatility is survived with position sizing, risk is avoided with research. Sizing a position so that a 60% drawdown is uncomfortable rather than ruinous handles volatility. Nothing about sizing protects you from owning something whose thesis has broken.

Which is why both jobs need doing. Size for the volatility, research for the risk, and set an alert at the level where the thesis would be in question — so the review is triggered by the market rather than by whether you happened to be paying attention that week.

Never miss a move in the markets you follow

Set a price or percentage alert once and get a push notification the moment it triggers — free, with quiet hours so nothing wakes you at 3am.
