A personal privacy checklist for expats and TRC holders who’d rather not become a data folktale
Living in Vietnam changes how your identity works.
Back home, your digital life is fragmented. In Vietnam, it becomes compressed. Facebook turns into infrastructure. Zalo becomes a de facto identity layer. Your phone number quietly replaces your signature. Your address circulates like a rumour.
None of this is malicious. It’s efficient. Vietnam is a low-trust, high-data environment that assumes you’re possibly a decent human being until proven otherwise.
The problem is that digital systems don’t forget, don’t contextualise, and don’t care if you meant to share that detail ten years ago while drunk in Bali and signing up for a forum about scooters.
You cannot erase yourself completely. Anyone telling you otherwise is selling something.
But you can delete most of your footprint, reduce your exposure dramatically, and stop leaking personal data like a cheap colander.
This is how to do it, properly, if you live in Vietnam, hold (or are applying for) a TRC, and would prefer not to outsource your identity to whatever app asked most nicely.
A quick reality check before we begin
Privacy maximalism is a fantasy. Total invisibility is for spies, criminals, and people who haven’t tried to open a bank account lately.
What you’re aiming for instead is intentional visibility.
People should find what you chose to publish.
They should not find your phone number, address, routines, purchase history, or a digital fossil record of every app you’ve ever tried and abandoned.
That’s not paranoia. That’s adult boundary setting.
How to do this without losing your weekend
Do this in two passes.
First pass is discovery and preparation. Second pass is deletion and lockdown. If you try to do everything at once, you will absolutely delete something you need for banking, visas, or work, and then you’ll spend three days explaining yourself to a customer service chatbot with the emotional warmth of a brick.
Create one simple tracking note. Nothing fancy.
For each item, record:
- Service or platform
- Email, phone number, or username used
- Action taken
- Date
- Any confirmation reference
You are becoming the archivist of your own digital life. It’s overdue.
Step 1: Audit your footprint like a Vietnamese system would
Most expats audit like tourists. Vietnam doesn’t see you that way.
Search yourself properly
Use Google and search in English and Vietnamese.
Search combinations like:
- Your full name
- Your name + Vietnam
- Your name + city
- Your phone number with +84 and without
- Your email address
- Your business name
Do not stop at page one. Vietnamese directories, cached pages, and scraped listings often sit further down.
If you only look at page one, you’re doing performative privacy.
Check Zalo, carefully
Zalo is not “just messaging”. It is an identity surface.
Check:
- Can someone find you by phone number alone?
- Does your profile photo show your face clearly?
- Are your workplace or location details visible?
- Are you still in old groups you forgot about?
Many expats discover, accidentally, that their phone number reveals their full name and face to strangers. That’s not a bug. That’s a design assumption.
Use your inbox as evidence
Search your email for:
Shopee, Lazada, Tiki, Grab, Be, Zalo, Momo, VNPay, Agoda, Traveloka, Booking, OTP, xác nhận, đăng ký
Every confirmation email is proof of an account. Build your list from there.
Step 2: Secure your core identity before you delete anything
This is where sensible adults pause before swinging the axe.
Lock down your primary email
Your email is the master key. If it’s weak, everything else is decorative.
Do this first:
- Change to a long, unique password
- Turn on two-factor authentication
- Remove old recovery phone numbers and emails
- Make sure your email is not publicly visible anywhere
Many Vietnam-based services rely on email or phone OTP alone. If those are compromised, everything downstream follows.
Decide what you actually need to keep
Most expats and TRC holders realistically need:
- One primary email
- One Vietnam phone number
- One e-wallet
- One ride-hailing app
- One food delivery app
- Banking, visa, and healthcare portals
- One professional public presence (usually a website or LinkedIn)
Everything else is optional, regardless of how “convenient” it claims to be.
Convenience is how data multiplies.
Step 3: Reduce Facebook and Zalo exposure first
Because this is where most leaks happen
In Vietnam, Facebook and Zalo are not social media. They are utilities with opinions.
Facebook, done properly
Do not just deactivate and hope for the best.
Before anything else:
- Remove your phone number
- Set email visibility to “Only me”
- Lock past posts to friends only
- Remove workplace, hometown, education if not essential
- Review tagged photos and untag aggressively
Then choose:
- Delete entirely, or
- Keep a stripped-down shell account used only for groups or business pages
Many professionals keep a minimal account with no personal posts, no photos, and no discoverable details. It works surprisingly well.
Zalo, with intention
Zalo deserves its own paragraph because it’s where most expats are careless.
Go into privacy settings and:
- Disable being found by phone number if possible
- Restrict profile and photo visibility
- Leave old groups
- Remove shared contact cards
- Replace your profile photo with something non-identifying if you keep the account
Zalo feels private. It isn’t. It’s just culturally trusted.
Step 4: Shopping, delivery, and “it’s just an app” platforms
Vietnamese platforms often store:
- Full name
- Phone number
- Address
- Purchase history
- Sometimes ID images
For platforms you keep:
- Delete saved addresses you don’t need
- Remove stored payment methods
- Turn off marketing notifications
- Remove profile photos and optional data
For platforms you don’t use anymore:
- Attempt full account deletion
- If deletion isn’t offered, blank the profile as much as possible
- Then uninstall
Uninstalling an app without deleting the account is like throwing away a key while leaving the door open.
Step 5: Remove yourself from search results and public listings
This is the slow, unglamorous part. It works anyway.
Ask search engines to stop displaying personal data
If Google shows your phone number, address, or private details:
- Submit a personal information removal request
- Include exact URLs
- Track outcomes
You don’t need to win every case. Reducing discoverability is the goal.
Contact site owners directly
Vietnamese site owners are often pragmatic.
Keep requests short and polite. No lectures. No threats.
Ask for removal of specific information and include the URL.
Most comply quietly.
Step 6: Data aggregation, Vietnamese style
Vietnam doesn’t have the same visible data broker industry as the US, but aggregation happens through:
- Property listings
- Business directories
- Professional associations
- Conference sites
- Cached scraper pages
Search your name plus:
liên hệ, địa chỉ, số điện thoại, thông tin
When you find something:
- Request removal
- If not possible, request anonymisation
- If neither works, request de-indexing
This is tedious. It’s also where real privacy gains happen.
Step 7: Clean your phone, not just your accounts
Your phone is your most enthusiastic informant.
Review app permissions one by one
Do this slowly.
- Remove location access unless essential
- Remove microphone and camera access from non-essential apps
- Disable ad personalisation
- Reset advertising IDs where possible
Many apps in Vietnam ask for far more access than they need. Most users never check. You are no longer “most users”.
Messaging apps
- Leave old groups
- Delete archived chats
- Clear media caches that contain ID photos, documents, contracts
Your phone often contains more sensitive material than your laptop ever did.
Step 8: Define “low-visibility leadership” for Vietnam
For most expat leaders and TRC holders, a sane setup looks like:
- One professional website as your public anchor
- One controlled social profile, minimal and intentional
- No public phone number unless required
- No public home address anywhere
- No casual posting of routines, locations, or travel plans
- Clear separation between private and public communication channels
This isn’t secrecy. It’s boundaries.
Step 9: Maintenance, because entropy always wins
Your footprint will grow back if you don’t maintain it.
Adopt this rhythm:
- Monthly: delete new accounts you don’t actively use
- Quarterly: search your name again
- Every six months: review phone permissions and Zalo/Facebook settings
And adopt one rule that solves most problems:
If a service does not need your real details, do not give them your real details.
That rule alone deletes more future footprint than any dramatic purge.
The contrarian truth most people miss
Privacy is not about hiding.
It’s about choosing.
If your digital presence is the result of default settings, forgotten sign-ups, and polite compliance, you don’t have an online identity. You have residue.
Reducing your digital footprint in Vietnam isn’t about fear. It’s about clarity.
You decide what’s visible.
You decide what persists.
You decide what follows you.
Everything else is just data doing what data always does when nobody’s paying attention.

The last laugh
Oh, and just when you think you have it covered, here’s two words that will wrinkle you: ‘wayback machine’. You’re welcome.
Like they said in the movie Sneakers, “there are no secrets.” You have at best six months before what you think is private ends up in a government database somewhere. As Mulder used to say, “the truth is out there.”
