Is imo Safe to Use? Privacy and Security Guide for Nepali Users
Before your next family call, it's worth knowing exactly what imo protects, what it doesn't, and where the real risk usually comes from — and it's rarely the encryption.
imo's 2026 privacy update added real protection — but understanding exactly what it covers matters more than assuming it covers everything.
Short Answer
- imo is reasonably safe for everyday, routine conversations with people you know and trust.
- Its strongest privacy protection, full end-to-end encryption, is available through an opt-in "Privacy Chat" and "Call Lock" feature added in a 2026 update, not applied automatically to every conversation by default.
- imo has not published an independently verifiable encryption protocol the way apps like Signal have, so its privacy claims rely on the company's own statements rather than third-party audit.
- The most common real-world risk for Nepali users isn't a data breach, it's scams and impersonation carried out through the app, which no amount of encryption prevents.
What "Safe" Actually Means for a Messaging App
When people ask whether an app is safe, they're usually really asking about a few different things at once: can someone intercept my calls, can the company itself read my messages, could my data leak or be sold, and could someone use the app to scam or manipulate me. imo's answer differs depending on which of these questions you're actually asking, which is why a simple yes or no undersells what's genuinely worth understanding here.
What imo Actually Encrypts, and What That Means
In mid-2026, imo rolled out a significant privacy update built around five features: expanded end-to-end encryption through a dedicated "Privacy Chat" system, a PIN-and-biometric-protected "Hidden Chat," disappearing messages with timers ranging from 30 seconds to 90 days, screenshot and screen-recording blocking, and "Call Lock" for encrypted voice and video calls. According to imo's own documentation, enabling Privacy Chat means only the sender and recipient can read the message content, not imo itself.
The important nuance
- Standard, everyday chats and calls on imo use encryption in transit, meaning data is protected while moving between your device and imo's servers, but this is a different, weaker guarantee than full end-to-end encryption.
- Full end-to-end encryption on imo is available specifically through Privacy Chat and Call Lock, features you need to actively turn on for a given conversation, rather than something applied automatically to every chat by default.
- This is a meaningful difference from apps like WhatsApp or Signal, where end-to-end encryption is the automatic, default state for every conversation with no setup required.
In practical terms: if privacy matters for a specific conversation, don't assume it's automatically protected the strongest way imo is capable of, check whether Privacy Chat or Call Lock is actually turned on for that conversation.
Does imo Sell or Share Your Data?
According to imo's own app store listing, the company states it does not share user data with third parties, and that data is encrypted in transit. The app does collect certain categories of information to function, including personal information and contacts, which is fairly standard for a messaging and calling app that needs to match you with people in your contact list. Community discussion around imo has raised a separate concern worth understanding: even when message content is protected through Privacy Chat, metadata, information like who you're talking to, when, and roughly from where, may still be collected for the app's own analytics purposes. This is a common characteristic across many messaging apps, not unique to imo, but it's a distinction worth knowing rather than assuming that "encrypted" means "nothing is collected."
How imo Compares on Independent Verification
One meaningful gap in imo's privacy story, compared to apps built specifically around privacy as their core feature, is independent verification. Signal, for example, publishes its encryption protocol openly and has been reviewed by independent security researchers repeatedly over the years. imo has not published a comparable detailed protocol whitepaper, and its client isn't open-source in the way Signal's is. This doesn't mean imo's encryption claims are false, but it does mean users are trusting the company's own statements rather than being able to independently verify them, a real distinction for anyone with a higher-stakes privacy need.
| Factor | imo | Apps Built Around Privacy (e.g., Signal) |
|---|---|---|
| Default encryption for all chats | Encrypted in transit by default; full end-to-end encryption requires opting into Privacy Chat | End-to-end encryption is the automatic default for every conversation |
| Published, independently verifiable protocol | Not currently published in detail | Openly published and independently audited |
| Metadata handling | Some metadata reportedly used for analytics even with content encrypted | Minimal metadata retention is a core design goal |
| Best suited for | Everyday conversations with trusted contacts, casual and family use | High-stakes confidential communication |
For a call to your family, imo's protections are genuinely reasonable. For a conversation where the content absolutely cannot leak under any circumstance, it isn't the tool built for that job — and honestly, imo doesn't claim to be.
Account Security: The Part You Actually Control
Regardless of how imo encrypts conversations, your account's real-world security depends heavily on habits within your own control.
Practical account security steps
- Your imo account is tied directly to your phone number, so protecting that number matters as much as protecting the app itself; be cautious about SIM swapping risks if you change carriers or SIM cards.
- Enable Hidden Chat with a PIN or biometric lock for any conversation you'd want protected if someone else picked up your unlocked phone.
- Turn on encrypted backup if you use Privacy Chat regularly, since reinstalling the app or switching phones without it will permanently lock you out of that protected chat history.
- Be selective about what you approve when the app requests permissions, particularly camera, microphone, and contacts access.
- Log out of imo on any shared or public device after use, and periodically check which devices are logged into your account if the app offers that option.
The Real Risk: Scams, Not Encryption
This is the part of imo's safety story most worth attention for Nepali users specifically, and it has very little to do with encryption strength. Messaging and calling apps, imo very much included, are a common channel for scams targeting migrant workers and their families: fake job offers, impersonation of recruitment agents or even relatives, requests for urgent money transfers from a "familiar" contact whose account has actually been compromised, and romance or friendship scams that build trust over weeks before asking for money. No level of encryption prevents this kind of manipulation, because the message itself is genuinely private, the danger is who's on the other end and what they're asking for.
Scam patterns worth recognizing
- An urgent, emotionally pressured request for money from a contact, especially one claiming to be stuck, injured, or in legal trouble abroad.
- A "recruitment agent" or "employer" contacting you directly through imo with a job offer that requires an upfront payment.
- A contact whose messaging style, spelling, or tone suddenly feels different, a common sign their account may have been compromised.
- Any request to share an OTP, verification code, or password, something a legitimate contact or company would never genuinely need from you.
If a message or call ever asks for money urgently, verify through a separate channel first, a phone call to a known number, a message to another family member, before sending anything. This single habit prevents far more harm than any app setting ever could.
So, Should You Use imo?
Reasonable to use if
- You're using it for everyday conversations and calls with family and people you already know and trust.
- You're comfortable checking and enabling Privacy Chat or Call Lock for any conversation where stronger protection matters to you.
- You follow basic account security habits, protecting your phone number, using Hidden Chat where appropriate, and staying alert to scam patterns.
Think twice if
- You need independently verified, audited encryption for genuinely high-stakes or sensitive communication.
- You're not comfortable with a company's own privacy claims without third-party verification.
- You're being asked, by anyone, for money or sensitive information through the app, regardless of how convincing the request seems.
Frequently Asked Questions
Is imo end-to-end encrypted by default?
Not for every chat automatically. Standard conversations use encryption in transit, while full end-to-end encryption is available through imo's opt-in Privacy Chat and Call Lock features, introduced as part of a 2026 update.
Has imo had a data leak?
imo states it does not share user data with third parties, and its app store data safety disclosures reflect this. As with any messaging platform, users should stay attentive to official app updates and security notices for the most current information.
Is imo safer than WhatsApp?
Not by default. WhatsApp applies end-to-end encryption automatically to every chat and call, while imo requires actively enabling Privacy Chat or Call Lock for equivalent protection on a given conversation.
What's the biggest privacy risk when using imo?
For most Nepali users, the biggest practical risk isn't encryption strength but scams and impersonation carried out through the app, fake job offers, urgent money requests, and compromised contact accounts, none of which encryption alone prevents.
