Which Android Permissions Should a Crypto App Ask For? 6 Red Flags to Refuse (2026)
Which Android permissions should a crypto app ask for?
A crypto app on Android should ask for very little: network access to reach its servers, notifications if you want alerts, and the camera only when you choose to scan a QR code. Requests for accessibility services, SMS, call logs or drawing over other apps are the red flags, because those powers let an app read your screen, intercept one-time codes or fake a confirmation button. This guide is educational, names six red flags and was checked against Android and Google Play documentation on 2026-11-10.
CoinX is GSPTeck's crypto projects hub, home of CoinDrop and Swappr. Both apps are on Android, so readers ask what a normal permission list looks like and what to refuse. The checks below work for any crypto app, ours included.
What kinds of permission does Android have?
Android sorts permissions into three main types: install-time, runtime and special. The Android permissions overview explains that each type sets how much restricted data or how many restricted actions an app can reach once the system grants it.
| Type | How you grant it | Examples |
|---|---|---|
| Install-time | Granted automatically when you install the app | Internet access |
| Runtime | A pop-up you can allow or deny while using the app | Camera, notifications (Android 13+), contacts, SMS, location |
| Special | A toggle you turn on yourself in system settings | Accessibility service, display over other apps, install unknown apps |
The practical rule: a runtime pop-up should appear when you use the feature that needs it, such as the camera when you tap a scan button. A special permission should almost never be needed by a wallet, earn or swap app.
Which permissions are normal for a crypto app?
Network access, notifications and an on-demand camera are the normal set for a crypto app. Each has an obvious job: network access fetches balances and rates, notifications report a finished swap or a reward, and the camera reads an address QR code.
- Network access. Install-time and automatic. Every online app has it.
- Notifications. Optional. Deny it if you don't want alerts; the app should still work.
- Camera. Only for scanning a QR code at the moment you scan. Our 4-step check for scanning a crypto QR code covers what to compare after the scan.
- Biometric or screen lock. Unlocking with a fingerprint doesn't hand the app your fingerprint; the system only answers yes or no.
The 6 red-flag permissions for crypto apps
Six requests deserve a hard look in any crypto app: accessibility, SMS, call logs, display over other apps, install unknown apps and contacts. The first four are the ones banking and crypto malware relies on.
- Accessibility service. It lets an app read what is on screen and act for you. Google Play's permissions policy says only services designed to help people with disabilities may declare themselves accessibility tools, and that any use enabling an app to "autonomously initiate, plan, and execute actions or decisions is strictly prohibited". A wallet or swap app has no reason to ask.
- SMS. SMS access exposes the one-time codes exchanges send by text. Google Play's SMS and Call Log policy limits these permissions to apps registered as the default SMS, Phone or Assistant handler, which a crypto app isn't.
- Call logs. Covered by the same Play policy and just as unnecessary.
- Display over other apps. An overlay can sit on top of a real screen. Android's tapjacking guidance describes a malicious app tricking the user into tapping a security-relevant control by obscuring the screen with an overlay.
- Install unknown apps. It turns one bad app into a channel for more. An app that tells you to allow it is asking to bring in code that skipped store review; see fake exchange APKs and sideloading.
- Contacts. Some apps use it to fill in a friend's email, but a crypto app works without it. Deny it and use the in-app address book instead.
One honest caveat: a large exchange app may request more than a small app, for example the camera for identity checks. The test is whether each permission matches a feature you can see, and whether the app still runs when you deny the ones you don't use.
How do you check an app's permissions on Android?
Check twice: before installing, read the Play listing's Data safety section, and after installing, open the app's permission list in system settings. The two answer different questions: what the developer says it collects, and what your phone actually lets it touch.
- Before you install: on the Play listing, open Data safety. Google Play Help says developers use this section to share how they collect, share and protect your data. It is the developer's own declaration, so treat it as a claim, not an audit.
- Confirm it's the real app: check the developer name and package ID first; how to verify an official crypto app on Google Play walks through it.
- After you install: go to Settings, Apps, the app's name, then Permissions. Menu names vary by phone maker, but every recent Android version lists allowed and denied permissions there.
- Check special access separately: accessibility and display-over-apps don't show as normal permissions. Look under Settings, Accessibility, and the special app access menu, and turn off anything you don't recognise.
What do CoinDrop and Swappr declare on Google Play?
On 2026-11-10, both apps' Play listings declare that no data is collected and that device or other IDs may be shared with third parties. Swappr is a free Android app for simple multi-coin crypto swaps, and CoinDrop is a free Android app for earning crypto daily with airdrop rewards, simple tasks and referrals.
| App | Data safety (checked 2026-11-10) | Where to get it |
|---|---|---|
| CoinDrop | No data collected; device or other IDs may be shared with third parties | CoinDrop on Google Play, coindrop.website |
| Swappr | No data collected; device or other IDs may be shared with third parties | Swappr on Google Play, swappr.website |
Declarations can change with any update, so re-read the live panel. Neither app needs your recovery phrase or private key, and no permission prompt should ever ask for one; our seed phrase vs private key vs password guide explains why.
What should you do if a crypto app asks for a red-flag permission?
Deny it, and if the app refuses to work without it, uninstall the app. If you already granted accessibility or overlay access to an app you don't trust, revoke it, uninstall the app, run Google Play Protect, and move funds from any wallet whose phrase was typed on that phone to a new wallet.
FAQ
Does a crypto wallet app need SMS permission?
No. Google Play limits SMS and Call Log permissions to apps set as the default SMS, Phone or Assistant handler. Codes sent by text can be typed by hand, and an authenticator app or security key is safer than SMS anyway.
Why is accessibility access dangerous for crypto apps?
Accessibility lets an app read the screen and act on your behalf, which malware can use to capture a recovery phrase as you type it or tap buttons for you. Google Play restricts it to tools built for people with disabilities, so a crypto app shouldn't ask for it.
Is camera permission safe for a crypto app?
Usually yes, when it is requested at the moment you tap a QR scan button. Choose "only while using the app" and compare the scanned address with the one you expected before you send.
Where do I see which permissions an Android app has?
Open Settings, Apps, choose the app, then Permissions. Special access such as accessibility or display over other apps is listed in separate settings menus, so check those too.
