Privacy Policy

1. Introduction and Agreement

Welcome to DataSentryX ("Service," "we," "us," or "our"), a suite of privacy protection products including mobile apps and browser extensions developed and operated by DataSentryX LLC, a limited liability company. This Privacy Policy explains how we collect, use, store, and protect your information when you use our Service.

This Privacy Policy is incorporated into and made part of our Terms of Service. DataSentryX LLC reserves the right to update this policy at any time. Continued use of the Service after any modification constitutes your acceptance of the revised policy.

2. Information We Collect

2a. Information You Provide Directly

We collect the following information that you voluntarily provide to us:

• Email address — collected when you create an account, subscribe, or opt in to receive product updates, security alerts, and company communications from DataSentryX LLC.
• Subscription and billing information — processed entirely by Apple's App Store (iOS), Google Play (Android), or Stripe (website purchases). DataSentryX LLC does not store your credit card or payment details on our systems.
• Subscription status — we store which plan your account is on (for example, Free, Pro, Family, Business, or Lifetime) and its renewal or expiry date, so your subscription works across all your devices. This is plan information only — we do not store your payment card details.
• Account device information — when you sign in to your account on a device, we store basic device details (a device label, platform such as iOS, Android, or browser, and the time it was last active) so we can apply your plan's device limit and let you manage your linked devices. This does not include the content, files, or activity on those devices.
• Sign-in security information — when you sign in to your account, we record standard session details such as your IP address and browser or app user-agent. This is used only to keep your account secure, maintain your session, and detect unauthorized access.
• Support communications — if you contact us for support, we may retain records of that correspondence.

2b. Information Generated On Your Device (Stays On Your Device)

The following information is analyzed and processed entirely on your device and is NOT transmitted to DataSentryX LLC or any third-party server:

• App permission data (camera, microphone, location, contacts, etc.)
• Privacy health score calculations
• App risk assessments
• Tracker block logs and activity
• Your protection settings and preferences

This on-device data is stored locally using your device's or browser's standard local storage. It is protected by each platform's own security and encryption, such as iOS data protection APIs and Android's application sandbox.

2c. Automatically Collected Technical Information

DataSentryX is built on a local-first architecture. All tracker detection, blocking, and privacy protection happens entirely on your device. The apps and browser extensions contain no analytics software, crash reporting SDKs, or telemetry systems.

Aside from the account device and sign-in security information described in section 2a, and the licence check described in section 2e, the apps and browser extensions do not automatically collect:

• Device type or operating system version
• Crash logs or diagnostics
• Usage data or screen views
• Any additional identifiers tied to you or your device

If Apple or Google collects crash diagnostics on our behalf, that is controlled entirely by your device settings (iOS: Privacy & Security > Analytics & Improvements; Android: Google settings > Usage & diagnostics) — not by us.

The only exceptions anywhere in DataSentryX are the anonymous counting on our public website, described in section 2d below, and the licence check in section 2e. If we ever add analytics that could identify you, follow you between visits, or track you across other websites, we will update this policy and ask for your explicit consent before collecting anything.

2d. Anonymous Website Counters (Website Only)

This section applies only to our public website at datasentryx.com. It does not apply to the iOS app, Android app, or browser extensions, which send us nothing of the kind.

So that we can tell whether our advertising actually reaches people, we count two things on our download page: that the page was opened, and that a store download button was pressed. Each count is stored as a single standalone row containing only:

• Which of the two events happened, and which store button (App Store, Google Play, Chrome, Edge, or Firefox)
• A short campaign label taken from the web address you arrived on (for example, ?src=fb), which identifies the advertisement, not you
• The two-letter country our network provider reports for the connection, and the date and time

These counters deliberately store no advertising or tracking cookie, no IP address, no browser user-agent, and no account, device, or visitor identifier of any kind. Because nothing is stored that links one row to another, these rows cannot be reassembled into a profile, a visit history, or a record of any individual person — not by us, and not by anyone who obtained the data. Nothing from these counters is sent to advertising networks or any other third party, and we run no third-party advertising pixel or tracking script anywhere on this website.

The campaign label is held in your browser's own session storage so it survives while you look around the site. It is not a cookie, it is never sent anywhere except as described above, and your browser discards it when you close the tab. Blocking it changes nothing about how the website works.

Opting out. We honor the Global Privacy Control (GPC) signal. If your browser sends it — some browsers enable it by default, others offer it in their privacy settings, and several extensions add it — this page records nothing at all for your visit: no counter is sent, and the campaign label is never even written to your browser's session storage. You do not need to ask us, and nothing about the website changes.

These counters are deleted automatically after 90 days, as described in section 10.

2e. Licence Checks (iOS & Android Apps Only)

To protect paid features from unauthorised use, piracy, payment fraud, and abuse, the iOS and Android apps periodically ask our server to confirm that this installation holds a valid licence and that your plan’s device limit is being respected. The answer we get back is a single yes or no.

A licence check may send:

• A random installation identifier generated by the app. It is not your advertising ID and not an identifier assigned to you by Apple, Google, or your device manufacturer.
• The platform (iOS or Android) and the version of the app you are running
• The licence identifier provided by the subscription-management provider named in section 6
• The two-letter country associated with the network connection. We do not store your IP address for this check.

We use this only for licence validation and to detect and stop piracy, payment fraud, and abuse of our paid features. It is never used for advertising, never used to build a profile of you, never used to follow you across other apps or websites, and never sold or shared with anyone.

A licence check tells us nothing about how you use the app. It carries no browsing history, no DNS lookups, no blocked-tracker records, and no settings — all of that stays on your device as described in section 2b. We do not require an account in order to verify a licence.

Licence-check information is kept only as long as it is reasonably needed for licence validation, fraud and abuse prevention, security, resolving disputes, and meeting our legal obligations, as described in section 10. You may request deletion at any time under section 9, except where a record relates to a licence withdrawn for fraud and is still needed for that purpose.

3. How We Use Your Information

We use the information we collect for the following purposes:

• To provide, operate, and maintain the DataSentryX Service and its features
• To send you product updates, new feature announcements, security tips, and company news to the email address you provided — you may unsubscribe at any time
• To process and manage your subscription
• To enforce your plan's device limit, and to detect and stop piracy, payment fraud, and abuse of our paid features — see section 2e
• To respond to your customer support requests
• To investigate and respond to customer-reported technical issues and improve the Service
• To improve and develop new features of the Service
• To comply with applicable legal obligations

4. Email Communications and Unsubscribe Rights

By providing your email address, you consent to receive communications from DataSentryX LLC including but not limited to: product updates, feature announcements, security alerts, promotional offers, and company news.

You may opt out of marketing emails at any time by:

• Clicking the "Unsubscribe" link in any email we send
• Emailing us at privacy@datasentryx.com with the subject line "Unsubscribe"

Please note that even after unsubscribing from marketing emails, we may still send you transactional or account-related communications such as billing receipts, password resets, and legally required notices.

5. Data Storage and Security

• Your email address and account information are stored on secure servers with industry-standard protections including encryption at rest and in transit.
• On-device privacy data (your scan results, scores, settings) remains on your device and is protected by your platform's own security framework (iOS, Android, or your browser). DataSentryX LLC cannot access this data.

In the event of a data breach affecting your personal information, we will notify you as required by applicable law.

6. Third-Party Services

DataSentryX LLC uses the following third-party services that may collect or process data under their own privacy policies:

• Apple App Store and Apple StoreKit — for iOS app distribution and in-app purchase processing. Subject to Apple's Privacy Policy.
• RevenueCat — for subscription management across platforms. Subject to RevenueCat's Privacy Policy.
• Cloud hosting and email delivery providers — our account system runs on established cloud infrastructure, and account-related emails (such as sign-in codes and receipts) are sent through a professional email delivery service. These providers process only the account information described in Section 2a, such as your email address, in order to operate the Service.
• Google Play Store and Google Billing — for Android app distribution and in-app purchase processing. Subject to Google's Privacy Policy.
• Chrome Web Store and Microsoft Edge Add-ons — for browser extension distribution. Subject to Google's and Microsoft's respective Privacy Policies.
• Mozilla Firefox Add-ons — for Firefox browser extension distribution. Subject to Mozilla's Privacy Policy.
• Stripe — for payment processing on our website and web-based subscriptions. Stripe collects payment card data directly and DataSentryX LLC does not store your card information. Subject to Stripe's Privacy Policy.

We are not responsible for the privacy practices of third-party services. We encourage you to review their privacy policies independently. We do not control how these third parties handle your data.

6a. DNS Resolution (iOS & Android Protection)

When protection is turned on in the DataSentryX iOS and Android apps, your device's DNS lookups (the requests that translate website names into network addresses) are resolved through the public DNS services operated by Cloudflare (1.1.1.1) and Google (8.8.8.8). This is how DataSentryX filters tracker domains while keeping all analysis on your device.

• DataSentryX LLC never sees, stores, or transmits your DNS lookups or browsing activity — filtering decisions and statistics are processed and kept entirely on your device.
• Cloudflare and Google process these lookups under their own privacy policies, as any DNS provider does. No account information or device identifiers from DataSentryX are attached to these lookups.
• When protection is turned off, your device returns to the DNS service configured by your network or carrier and DataSentryX performs no DNS processing.

The browser extension does not change your DNS settings; it filters tracker requests inside the browser using each browser's built-in content-blocking APIs.

7. Platform and App Store

DataSentryX is distributed through multiple platforms including Apple's App Store (iOS), Google Play Store (Android), Chrome Web Store (Chrome extension), Microsoft Edge Add-ons (Edge extension), and Mozilla Firefox Add-ons (Firefox extension). Each platform may collect certain information as part of the app download and distribution process. This collection is governed by each platform's own Privacy Policy and is outside our control. DataSentryX LLC is an independent developer and is not affiliated with Apple Inc., Google LLC, Microsoft Corporation, or Mozilla Corporation.

The Service uses platform-approved system APIs available on each supported platform to perform tracker detection and blocking. All processing occurs entirely on your device. DataSentryX does not transmit browsing activity, DNS requests, tracker logs, or app usage content to DataSentryX LLC servers. These system APIs operate under each platform's own security and privacy controls. DataSentryX LLC does not have access to data processed by these system frameworks beyond what is explicitly described in this policy.

8. Children's Privacy

DataSentryX is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately at privacy@datasentryx.com and we will take steps to delete such information.

If we discover that we have collected personal information from a child under 13, we will promptly delete it from our records.

9. Your Privacy Rights

Depending on your location, you may have the following rights regarding your personal information:

• Access — the right to request a copy of personal information we hold about you
• Correction — the right to request correction of inaccurate personal information
• Deletion — the right to request deletion of your personal information, subject to certain legal exceptions
• Portability — the right to receive your data in a portable format
• Opt-out of marketing communications — at any time, as described in Section 4

California residents may have additional rights under the California Consumer Privacy Act (CCPA). EU/UK residents may have additional rights under GDPR. To exercise any of these rights, contact us at: privacy@datasentryx.com.

We will respond to verifiable requests within 30 days. We may need to verify your identity before processing your request.

No Sale of Personal Information

DataSentryX LLC does not sell, rent, trade, share, or otherwise disclose your personal information to data brokers, advertisers, or third parties for monetary or commercial gain.

Because DataSentryX operates using a local-first architecture and does not collect browsing history, tracker logs, DNS requests, or app activity from your device, we have no such information available to sell.

10. Data Retention

We retain your email address and account information for as long as your account is active or as needed to provide the Service. If you delete your account or request deletion, we will remove your personal information from our active systems within 30 days, subject to any legal retention requirements.

On-device data is controlled entirely by you. Deleting the Service from your device will remove all locally stored data.

On-device activity data is also pruned automatically, with no action needed from you. In the iOS app, daily blocked and detected counts are kept for a rolling 30 days; in the Android app, they are kept for up to 90 days. On both apps, the tracker observation cache used to calculate risk assessments is limited to 2,000 domain entries and automatically discards entries not seen in the past 30 days. You can erase all of this data at any time from within the app using Settings → Reset Privacy Dashboard. Browser extension data is stored in your browser's own local storage and is removed when you uninstall the extension or clear its data.

The licence-check information described in section 2e is kept only as long as it is reasonably needed for licence validation, fraud and abuse prevention, security, resolving disputes, and meeting our legal obligations. Records for an installation that has stopped checking in are deleted automatically once they are no longer needed for those purposes; records relating to a licence withdrawn for fraud are kept until that matter is resolved.

The anonymous website counters described in section 2d are deleted automatically 90 days after they are recorded. Because they contain no identifier of any kind, they cannot be traced back to you, and deleting your account does not affect them — there is nothing in them to connect to an account.

DataSentryX LLC never receives or stores your DNS lookups, browsing history, or tracker activity on our servers, so we hold no such data to retain, disclose, or delete. The tracker information described above exists only on your device.

11. Limitation of Liability and Disclaimer

DataSentryX is a privacy protection tool that uses on-device blocking technology — Apple's Network Extension framework on iOS, a local VPN service on Android — and browser extension technology (Chrome, Edge, and Firefox) to detect and block outgoing tracker connections in real time. All detection and blocking occurs entirely on your device — no data is transmitted to DataSentryX LLC servers. It is NOT a guarantee of complete privacy, security, or anonymity.

DataSentryX LLC expressly disclaims any warranty, express or implied, including but not limited to:

• Any warranty that the Service will prevent all data collection, tracking, surveillance, hacking, identity theft, or data breaches
• Any warranty of fitness for a particular purpose or merchantability
• Any warranty that the Service will be error-free, uninterrupted, or free of viruses or other harmful components
• Any warranty regarding the completeness or accuracy of privacy scores, risk ratings, or tracker counts displayed in the Service. While these figures reflect real tracker activity detected on your device by our on-device detection system, the Service cannot guarantee detection of every tracker, and tracker behavior may change at any time without notice.

IN NO EVENT SHALL DATASENTRYX LLC'S TOTAL CUMULATIVE LIABILITY TO YOU EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID FOR THE APP IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR (B) ONE HUNDRED DOLLARS ($100.00).

12. Additional Limitations

The following additional limitations apply to your use of DataSentryX:

• The Service cannot and does not monitor, intercept, or control data transmitted within apps you choose to open and use. Once you enter a third-party application, that application's own data practices apply.
• Free Plan: Privacy scores and risk ratings reflect real tracker activity detected on your device by our on-device detection system and are not guarantees of absolute risk levels. Pro Plan: Privacy scores reflect real-time tracker data detected and blocked by your active protection — these numbers are actual tracker attempts recorded on your device. Neither plan can guarantee detection of every tracker, as tracker behavior and domains may change at any time.
• Free Plan: Tracker detection is active and displays real numbers of tracking attempts detected on your device in real time. Detected trackers are shown but not blocked. Pro Plan: Tracker blocking is active by default and automatically blocks tracker domains detected by your on-device protection system when protection is enabled. Users may enable or disable protection at any time through the app settings. DataSentryX LLC is not responsible for tracking that occurs while protection is disabled by the user. Neither plan can detect or block first-party trackers — data sent directly to an app's own servers cannot be intercepted by any third-party service.
• DataSentryX LLC is not responsible for the privacy practices, data collection, or security of any third-party applications installed on your device, even those identified in the Service's risk assessments.
• The Service's effectiveness may be reduced or eliminated by operating system or browser updates, changes to third-party applications, or changes to platform frameworks such as Apple's Network Extension framework.
• DataSentryX LLC does not provide legal advice. Nothing in the Service or this Policy constitutes legal advice. If you have specific legal concerns about data privacy, consult a qualified attorney.
• Use of the Service does not create an attorney-client relationship, fiduciary relationship, or any other professional services relationship between you and DataSentryX LLC.
• DataSentryX LLC reserves the right to discontinue the Service or any feature at any time without liability.
• DataSentryX LLC does not guarantee uninterrupted availability of the Service or its features.

13. Indemnification

You agree to indemnify, defend, and hold harmless DataSentryX LLC, its members, managers, employees, agents, and licensors from and against any claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees) arising out of or in any way connected with: (a) your use of the Service; (b) your violation of this Privacy Policy or our Terms of Service; (c) your violation of any third-party rights; or (d) any claim that your use of the Service caused damage to a third party.

14. Governing Law and Dispute Resolution

This Privacy Policy shall be governed by and construed in accordance with the laws of the United States and the state in which DataSentryX LLC is registered, without regard to conflict of law principles.

Any dispute arising from or relating to this Privacy Policy or the Service shall first be attempted to be resolved through good-faith negotiation. If negotiation fails, disputes shall be resolved by binding arbitration in accordance with the American Arbitration Association rules, and you waive any right to a jury trial or class action lawsuit.

15. Contact Us
