Privacy & Blocking
DataSentryX is a privacy protection company built for regular people — not tech experts.
Every day, hundreds of invisible tracking companies follow you across the internet without your knowledge or consent. Most people never see it happening. DataSentryX helps you understand and reduce that tracking with simple tools that work quietly in the background.
Our browser extension for Chrome, Edge, and Firefox monitors every connection your browser makes and blocks known tracking companies before they can collect your data. Our iOS and Android apps bring the same protection to your phone — blocking trackers that hide inside your favorite apps, monitoring privacy risks, and managing dangerous permissions in plain English.
No complicated settings. No technical knowledge required. One tap and you are protected.
Most privacy tools are built by engineers for engineers — complicated, cold, and full of technical language. DataSentryX was designed from day one for busy families and everyday people who want stronger privacy without needing a computer science degree.
DataSentryX protects your privacy directly on your device — not through our servers. Instead of blindly blocking entire websites, it intelligently blocks invasive tracking requests while allowing important things like logins, payments, videos, email, and security systems to continue working normally.
- •Block hidden trackers
- •Reduce behavioral profiling
- •Remove tracking parameters from links (browser extension)
- •Detect fingerprinting attempts
- •Preserve website functionality whenever possible
The goal: strong privacy protection without constantly breaking websites.
Most blockers focus mainly on huge blocklists. DataSentryX focuses on smarter protection:
- •Request-level protection rather than whole-site blocking
- •Lower website breakage through compatibility-aware blocking
- •Optional Strict Mode that blocks suspected trackers by name pattern (paid plans)
- •Quiet automatic protection that runs in the background
Instead of trying to "break the internet," DataSentryX is designed to reduce invasive tracking while keeping everyday browsing working normally.
Yes. DataSentryX uses a combination of our own privacy intelligence and tracker research, and publicly available open-source privacy and security research — including community-maintained projects such as Steven Black Hosts, The Blocklist Project, URLhaus, AdAway, Tiuxo Hosts, HostsVN, and others.
DataSentryX does not rely solely on any single third-party source. Domains are reviewed, categorized, filtered, deduplicated, and integrated into our own protection framework. Additional compatibility checks are applied to help reduce website breakage while improving privacy and security.
For full attribution, licensing, and open-source acknowledgements, see the Acknowledgements section within the app.
Not all tracking domains publicly reveal which company operates them. Some companies frequently create new domains, rotate infrastructure, or route tracking through generic-looking addresses.
When DataSentryX detects or blocks a domain but can't confidently match it to a known company, it's labeled "Unknown" — the connection still matched our protection rules; we just can't name the company behind it yet.
By default, DataSentryX blocks only trackers that have been verified by our intelligence system — this keeps websites and apps working smoothly. Strict Mode is an optional setting for paid plans that goes one step further: it also blocks connections to domains whose names match well-known tracker patterns (like "analytics", "telemetry", or "pixel"), even before those domains are formally verified.
Strict Mode never touches login, payment, or security services, so signing in and checking out keep working. Rarely, a new or uncommon service may be affected — if something breaks, add that site to Allowed Sites or turn Strict Mode off in Settings.
Strict Mode is off by default and available on Pro, Family, and Business plans. You can turn it on anytime in the app's Settings.
On Chrome, Edge, and Firefox — The extension monitors network requests in real time and blocks invasive tracking, fingerprinting, hidden telemetry, and behavioral profiling before data leaves your browser.
On iPhone and Android — DataSentryX uses the privacy protection systems built into the operating system to filter tracking connections across apps and websites locally on your device — helping reduce hidden trackers, invasive analytics, behavioral profiling, and advertising telemetry, while still allowing logins, payments, email, streaming, and security verification to work normally.
Everything runs quietly in the background with minimal interruption to normal browsing and app usage.
DataSentryX uses Apple's official NEPacketTunnelProvider technology to provide privacy protection on iOS.
This runs a lightweight, on-device VPN that inspects DNS requests locally, helping reduce tracking activity across apps and websites by blocking connections to known privacy-invasive domains before they are reached.
We chose this architecture because it works entirely on your device — no traffic is routed through external servers — while giving DataSentryX the flexibility to make intelligent decisions about which connections should be blocked, observed, or allowed.
Our protection is designed around a simple principle: block trackers, not websites. Rather than aggressively blocking everything, DataSentryX aims to reduce invasive tracking while minimizing interruptions to browsing, streaming, banking, shopping, and other everyday activities.
Most protection decisions are performed locally on your device, helping keep your privacy data under your control.
DataSentryX uses Android's official VpnService API to provide privacy protection on Android.
This runs a lightweight, on-device VPN that inspects DNS requests locally, helping reduce tracking activity across apps and websites by blocking connections to known privacy-invasive domains before they are reached.
We chose this architecture because it works entirely on your device — no traffic is routed through external servers — while remaining battery-friendly, stable for everyday use, and compatible with normal browsing, streaming, banking, and shopping.
Our protection is designed around a simple principle: block trackers, not websites. Rather than aggressively blocking everything, DataSentryX aims to reduce invasive tracking while minimizing interruptions to the services you use every day.
Most protection decisions are performed locally on your device, helping keep your privacy data under your control.
Tracking happens every single second you are connected to the internet — whether you are shopping, reading the news, or just leaving your phone on the counter.
Step 1 — You visit a website or open an app. That site or app quietly sends a signal to dozens of invisible companies in the background. It takes milliseconds. You never see it.
Step 2 — Trackers collect everything about you. In that split second they capture your IP address, device fingerprint, what you looked at, how long you looked, what you searched for, what apps you have installed, your approximate income, whether you have children, your health concerns, and your political views — all based on browsing patterns.
Step 3 — They build your profile. Every time you appear on any site that uses their tracker, they add more data. Over weeks and months your profile becomes extraordinarily detailed.
Step 4 — They sell your profile. To advertisers, insurance companies, employers, political campaigns, data brokers, and anyone willing to pay. The average American's data profile is sold hundreds of times per year.
Step 5 — Cross-device tracking follows you everywhere. You search for something on your laptop. Twenty minutes later you see ads for it on your phone. That is cross-device tracking — trackers link your devices together using your home WiFi, account logins, and device fingerprint.
DataSentryX sits between your device and the internet and cuts tracker connections before any data leaves. The tracker loads but gets nothing.
Many apps and system services continue making background network requests even when you are not actively using them — including push notifications, app refresh activity, analytics, ad network requests, cloud sync, and tracking scripts running in the background.
Some apps regularly "check in" with servers throughout the day even while idle. DataSentryX continues monitoring and blocking those requests in the background, which is why the count may keep increasing even when your phone appears inactive.
Your device constantly connects to many background network services even when only a few apps are visible. A single app may contact analytics services, ad networks, crash reporting systems, content delivery networks, and tracking domains simultaneously.
DataSentryX monitors network activity at the DNS/network level — not by counting open apps. The number shown reflects all network connections and tracking requests detected across your device, including background activity.
Your total blocked count includes more than just the website you are currently viewing. DataSentryX can block trackers from the active website, background browser requests, preloaded page requests, browser syncing, and hidden third-party tracking activity happening behind the scenes.
For example, if a website shows 62 blocked trackers but your total shows 100, the remaining blocks likely came from background browser activity or other network requests running behind the scenes.
When you visit a website or open an app, it may automatically connect to additional companies for advertising, analytics, tracking, social media integrations, telemetry, and behavioral profiling. These third-party domains appear unfamiliar because you never visited them directly — they were loaded automatically in the background.
A single webpage can quietly connect to dozens of outside services behind the scenes. DataSentryX helps identify and monitor these hidden connections so you can better understand which companies are attempting to collect data during normal browsing.
Not all websites use the same amount of tracking technology. Some load only a few external connections, while others load dozens of analytics, advertising, and telemetry services in the background.
DataSentryX blocks requests that match its protection rules. A lower blocked count simply means there is less tracking activity on that particular page — protection is still fully active.
Yes. DataSentryX is designed to block trackers while preserving logins, payments, streaming, security verification, and normal website functionality whenever possible. Some services that are essential for websites and apps to function — like login systems, payment processors, and video delivery — are protected to minimize the chance of breakage.
Yes. DataSentryX is designed to be especially cautious around banking, healthcare, government, payment, and authentication systems to reduce the chance of breakage.
Yes. Streaming and media delivery services are protected to help ensure compatibility. DataSentryX aims to block surveillance, not interrupt your entertainment.
DataSentryX is designed to minimize breakage, but if something stops working:
- 1.Add the site to Allowed Sites, then reload the website or app.
- 2.If it's still not working, temporarily disable protection and reload again.
- 3.If disabling protection fixes it, re-enable protection — the site should now work with it added to Allowed Sites.
If the problem continues, please contact us at support@datasentryx.com with the website or service name and a brief description. We'll investigate and improve compatibility.
Allowed Sites lets you tell DataSentryX not to block trackers on a specific website or app you trust and want to keep working normally. Once added, that site's main domain and its subdomains are no longer blocked, going forward.
It's meant for cases where a site you use regularly is affected by our protection — for example, a login page, embedded form, or feature that depends on a domain we'd otherwise flag as a tracker. Adding it to Allowed Sites is the fastest fix, without turning off protection everywhere.
Keep in mind Allowed Sites only covers domains that belong to that site — not every third-party ad or tracker a page might load (see "Why do some websites still break…" below).
When you add a site to Allowed Sites, we unblock that site's main domain and its subdomains. But our iOS and Android apps block trackers at the DNS level, and DNS has no way of knowing which website a request actually came from — it only sees the domain being contacted. So if a site loads ads, analytics, or fingerprinting scripts from a separate third-party domain (which most sites do), that third-party domain can still be blocked, since it isn't part of the site you allowed.
The browser extension for Chrome, Edge, and Firefox on desktop doesn't have this limitation. It works at the page level and can see exactly which site a request is loading on, so allowing a site there unblocks everything on that page, including third-party content.
This is the same DNS limitation described above. Allowing a site only unblocks its own domain and subdomains — it doesn't unblock third-party domains that page happens to load. If the broken piece (a login button, a form, a payment widget) is actually served from a separate third-party domain, that domain can still be blocked even though the site itself is allowed.
If you know which domain is causing the problem, you can add that specific domain to Allowed Sites as well. Otherwise, contact us at support@datasentryx.com with the site name and we'll help figure out what's being blocked.
Yes. DataSentryX is designed to identify and block many forms of browser and device fingerprinting used for tracking across websites and apps.
DataSentryX focuses primarily on blocking trackers and reducing surveillance. Some ads may disappear because their tracking systems are blocked, but ad blocking is not the primary goal.
DataSentryX is built to run efficiently in the background and is optimized to minimize impact on normal browsing, streaming, and app usage. On iOS, protection runs through Apple's on-device network framework; on Android, through a local on-device VPN — so your data isn't routed through external servers.
DataSentryX uses privacy-protection technologies provided by your operating system, but it is not a traditional VPN — your traffic is not routed through company-owned servers, and protection decisions are made locally on your device.
Instead, DataSentryX works at the DNS level. DNS requests are the small lookups your device makes to translate a website name into a network address before connecting. DataSentryX inspects these lookups on your device and blocks the ones headed to known tracker domains — so the tracker connection never happens. All of your other internet traffic flows directly to its destination as normal.
Because iOS and Android allow only one active VPN connection at a time, DataSentryX cannot run at the same time as another VPN app. If you use a separate VPN, you can switch between it and DataSentryX as needed.
On iPhone, DataSentryX uses Apple's VPN framework, and iOS automatically disables iCloud Private Relay while VPN protection is active. On Android, it uses Android's built-in VPN framework.
Because we actively audit and minimize third-party tracking on our website. During development of datasentryx.com, we reviewed every external service, script, and resource loaded by the site and removed anything unnecessary or privacy-invasive — including disabling Cloudflare Web Analytics and replacing externally hosted Google Fonts with local fonts to reduce unnecessary external connections.
We do not create special exceptions for our own domain. If a request matches our protection rules, it is treated the same as any other website. As a privacy-focused company, our own website follows the same standards we encourage for everyone else.
Currently, DataSentryX is proprietary software.
No. DataSentryX is a preventive privacy tool designed to help reduce data collection before it happens. It cannot remove personal information that has already been collected, shared, or sold by third parties.
Data removal typically requires contacting data brokers and organizations directly and submitting privacy or deletion requests — a process that can be time-consuming with varying results depending on applicable privacy laws.
Our goal is to help reduce future data collection by blocking many of the trackers and connections commonly used for advertising, analytics, and profiling.
Pricing & Plans
No. The free plan is designed for visibility and privacy awareness, not active blocking. Think of it like a privacy dashboard — you can see what's happening on your device before deciding if you want active protection.
Free Plan shows you: which trackers are detected, which websites or apps are attempting tracking, tracker activity counts, and privacy and permission insights.
Pro Plan actively: blocks tracking requests, reduces behavioral profiling, removes tracking parameters from links (browser extension), detects fingerprinting activity, and helps preserve normal browsing — running quietly in the background with no complicated setup.
Because privacy tools should not be limited only to people who can afford subscriptions. Our free plan is designed to help people understand what is happening to their data and improve their privacy without paying anything.
With the free plan you can see tracker activity in real time, view privacy risk reports, identify apps with high-risk permissions, learn how to reduce unnecessary access to your camera, microphone, and location, and get step-by-step privacy guidance in plain English.
We believe informed users make safer decisions. The Pro plan then adds automatic background protection that actively blocks invasive tracking while you browse and use apps normally.
Turning off permissions like camera, microphone, and location is an excellent first step — and the free plan helps you do that easily. However, app permissions are only one part of privacy protection.
Many apps and websites still communicate with analytics, advertising, telemetry, and tracking services in the background during normal use. These connections can continue even when sensitive permissions are disabled.
The simplest way to think about it: the free plan helps you improve your privacy settings. Pro actively reduces tracking while apps and websites are running.
Creating an account links your subscription to you instead of to a single device. This lets you switch to a new device if you're on a plan that only covers one device, or use DataSentryX on multiple devices at the same time if you're on a plan that supports more than one.
Don't worry — deleting your account does not delete a plan you purchased through the App Store or Google Play. That purchase stays tied to your Apple ID or Google account, even if you delete and reinstall the app.
To restore it: open DataSentryX on your iPhone or Android device, tap Upgrade, and at the bottom of the pricing screen tap "Restore Purchases". Make sure you're signed in with the same Apple ID or Google account you originally used to buy it.
Important: if you bought a plan on our website with a card, that subscription is tied to your account itself. Deleting your account cancels that subscription and stops billing — there is nothing to restore, so to restore your service, you will have to subscribe again.
Yes. Create an account first, then sign out of DataSentryX on your old device and sign in with that same account on the new device. Your subscription moves with your account, not with the device.
No. Signing out resets the app to Free on purpose — it gives you a clean slate so there's never any confusion about which account's plan is active (for example, if you switch between two accounts).
Your purchase is safe and there are two ways to get it back:
Sign back in. If your plan is linked to your DataSentryX account, signing in restores it instantly — on any device, up to your plan's device limit.
Tap "Restore Purchases". If you bought through the App Store or Google Play, open Upgrade and tap Restore Purchases at the bottom of the pricing screen — no sign-in needed, as long as the device uses the same Apple ID or Google account that made the purchase.
You can change your plan or unsubscribe anytime by logging into your account at datasentryx.com/login, or through Settings in the app.
Upgrades (for example Pro → Family, or Family → Business) take effect immediately and are prorated — you're only charged the difference for the remaining time in your current billing cycle, and your new device limit and features unlock right away.
Downgrades (for example Business → Family, or Family → Pro) take effect at the end of your current billing cycle. You keep your current plan's features and device limit until then, and you're billed at the new, lower rate starting with your next renewal.
You can change plans anytime from your account page, or from your subscription settings in the Apple App Store or Google Play if that's where you subscribed.
There are three ways to subscribe:
1. On iPhone or iPad — subscribe directly inside the DataSentryX app through the Apple App Store.
2. On Android — subscribe directly inside the DataSentryX app through Google Play.
3. Online — subscribe directly at datasentryx.com.
If you subscribe inside the app, no account is required — your subscription works right away on that device. However, if you'd like to use your subscription on another device, create a free account in the app's Settings after subscribing. Your subscription will then follow your account instead of the device.
If you subscribe on the website, your account is created for you as part of checkout — you simply enter your email address and confirm it with a verification code, then complete your purchase.
How you cancel depends on where you originally subscribed.
If you subscribed through the Apple App Store (iPhone or iPad): open Settings, tap your name at the top, tap Subscriptions, select DataSentryX, and tap Cancel Subscription.
If you subscribed through Google Play (Android): open the Play Store app, tap your profile icon in the top right, tap Payments & subscriptions → Subscriptions, select DataSentryX, and tap Cancel subscription.
After you cancel through the App Store or Google Play, your Pro protection continues until the end of your current billing period, and you will not be charged again. You can then keep your account on the free plan at no cost, or delete your account at any time — either in the app or from your account page on this website. Please note that deleting your account does not cancel an App Store or Google Play subscription, so always cancel the subscription first.
If you subscribed on this website: you can cancel anytime from your account page, and your subscription runs until the end of the billing period. Deleting your account also cancels your subscription and stops billing, so no separate cancellation step is needed.
Yes — as long as your current billing period hasn't ended yet, you can resume a canceled subscription and keep your same plan without losing anything.
If you subscribed on this website: log into your account page and click Resume. Billing picks back up at your next renewal date — you won't be charged immediately.
If you subscribed through the Apple App Store or Google Play: open your subscriptions in Settings (iPhone/iPad) or the Play Store app (Android), select DataSentryX, and choose to resume or renew the subscription.
If your billing period has already ended and the subscription has expired, you'll need to subscribe again as normal.
Your Privacy
No. DataSentryX is designed to block tracking connections — not read your personal content. Our protection system can see when an app or website tries to contact a known tracking or advertising domain, but it does not see your messages, emails, photos, videos, passwords, payment information, what you type, or browsing content inside apps.
Most modern app traffic is encrypted, and mobile operating systems isolate apps from each other for security and privacy.
We collect the minimum information required to operate your account:
- •Your email address
- •Subscription and account status
- •Basic device info (platform, last active) to enforce your plan's device limit, etc.
We do NOT collect:
- •Browsing history, tracker activity, or block logs
- •App usage, messages, emails, or contacts
- •Personal files, passwords, or payment card information
Privacy activity and protection data stay on your device whenever possible.
No. Payments are securely processed by Apple's App Store (iPhone), Google Play (Android), or Stripe (website), depending on where you subscribe — your payment details are never stored on DataSentryX servers.
No. DataSentryX is designed to protect privacy, not collect personal data. Browsing history, cookies, account information, and personal identifiers are not collected. Privacy analysis is performed locally on your device whenever possible.
No. DataSentryX does not access your passwords, messages, photos, documents, or any personal content.
