App: Swift Browser (package com.asiadragon.private.browser) · Developer: Asia-dragon · Effective date: October 16, 2026
This Privacy Policy explains what information Swift Browser (the "App") processes, why, who receives it, and the choices you have. "We", "us" and "our" mean Asia-dragon, the developer of the App. By using the App you acknowledge the practices described here. If you do not agree, please do not use the App.
1. Summary of how the App works
Swift Browser is a web browser for Android. You do not create an account and you do not sign in. Your browsing history, bookmarks, open tabs, download list and settings are stored on your device and are not uploaded to servers operated by us.
The App is supported by advertising and includes third-party SDKs for advertising, analytics, crash reporting and install attribution. These SDKs automatically process certain device and usage data (for example the Advertising ID, device and app information, IP address and crash logs), as described in Sections 2 to 4. Which advertising SDKs and ad formats are active can vary between releases of the App; this policy covers all SDKs listed below that are included in the App.
2. Information we and our partners process
| Category | Examples | Where it goes | Why |
|---|---|---|---|
| Browsing data on your device | Browsing history, bookmarks, open and incognito tabs, download list and downloaded files, cookies and web storage, saved settings, ad-block lists | Stays on your device. We do not receive it. | To provide the browser features you use |
| Search queries and addresses you enter | Words typed in the search box, web addresses you open | Sent from your device to the search engine you select (Google, Bing or DuckDuckGo) or to the website you open | To show you search results and web pages |
| Advertising ID and ad data | Google Advertising ID (or an equivalent device advertising identifier), ad requests, ad impressions, clicks and ad-revenue events | Google AdMob and the ad networks listed in Section 4 | To show, measure and limit advertising, and to prevent fraud |
| Device and app information | Device model, operating system version, language, screen size, app version, network type, approximate location derived from IP address | Advertising, analytics and attribution partners | Analytics, diagnostics, ad delivery, fraud prevention |
| IP address | The network address your device uses to connect | Servers of the SDK providers and the websites you visit, as is inherent to any internet connection | To deliver content and ads, and for security and fraud prevention |
| App interactions | Screens viewed, features used, session information | Firebase Analytics, Adjust, AppsFlyer, Meta (Facebook SDK), TikTok Business SDK | To understand usage, measure marketing and improve the App |
| Crash and diagnostic data | Crash logs, stack traces, device state at the time of a crash, performance data | Firebase Crashlytics (Google) | To find and fix bugs and keep the App stable |
| Install referrer | The campaign or source through which the App was installed | Google Play Install Referrer API, Adjust, AppsFlyer, Meta, TikTok | To measure how the App was found and the effectiveness of marketing |
| Remote configuration | App settings fetched from the server | Firebase Remote Config | To adjust App behavior and settings without an update |
We do not ask you for your name, email address, phone number or any account details inside the App. The App does not request access to your location (GPS), camera, microphone, contacts, calendar, SMS or call log through Android permissions.
If you contact us by email, we receive your email address and the content of your message, which we use only to respond to you.
3. Android permissions the App uses
| Permission | Purpose |
|---|---|
| INTERNET and ACCESS_NETWORK_STATE | Load web pages and check whether a connection is available |
| AD_ID (com.google.android.gms.permission.AD_ID) | Allows advertising and attribution SDKs to read the Advertising ID |
| FOREGROUND_SERVICE and FOREGROUND_SERVICE_SPECIAL_USE | Keep the optional Secure DNS feature running and show its notification (Section 5) |
| POST_NOTIFICATIONS | Show the notification that appears while Secure DNS is active |
| WRITE_EXTERNAL_STORAGE (Android 9 and lower only) | Save files you choose to download on older Android versions |
Some SDKs add their own standard permissions to the App (for example Wi-Fi state, vibration and wake lock, and Android Ads Services permissions). These are used by those SDKs only for the purposes described in this policy.
Websites you visit may ask to use features such as your location, camera or microphone through the browser's own permission prompt. Those prompts are shown by the page you are visiting; the App itself does not hold those Android permissions, and you can allow or refuse each request.
4. Third-party services (advertising, analytics, attribution)
The App contains advertising. We use Google AdMob and ad mediation, which lets several ad networks compete to show ads. These providers act as independent controllers or service providers under their own privacy policies:
- Google AdMob / Google Mobile Ads SDK, Google User Messaging Platform (consent) — How Google uses information · Google Privacy Policy
- Firebase Analytics, Firebase Crashlytics, Firebase Remote Config (Google) — Firebase privacy information
- Meta Audience Network and Facebook SDK — Meta Privacy Policy
- Mintegral — Privacy policy
- Pangle (TikTok for Business) and TikTok Business SDK — Pangle · TikTok Privacy Policy
- Vungle (Liftoff) — Liftoff privacy policy
- BIGO Ads — see the privacy policy published by BIGO
- Moloco — Privacy policy
- ironSource and Unity Ads (Unity) — Unity Privacy Policy
- AppLovin — AppLovin Privacy Policy
- BidMachine — Privacy policy
- InMobi — Privacy policy
- Fyber (Digital Turbine) — Privacy policy
- Adjust (attribution and analytics) — Adjust Privacy Policy
- AppsFlyer (attribution and analytics) — AppsFlyer Privacy Policy
- Google Play Install Referrer — covered by the Google Privacy Policy above
These partners may use the Advertising ID, device information, IP address and ad interaction data to deliver and measure ads (including personalized ads where permitted), to attribute installs, to detect fraud, and to provide analytics. We do not control how these third parties handle data under their own policies; please review them.
We do not sell your personal information for money. Under some laws (for example the California CCPA/CPRA) the disclosure of identifiers to advertising partners for ads may be considered "sharing" for cross-context behavioral advertising or a "sale"; see Section 9 for your choices.
5. Secure DNS feature
Secure DNS is an optional feature you turn on yourself. When enabled, the App uses the Android VpnService interface only to send your device's DNS lookups (the step that turns a website name into an address) to Cloudflare's public DNS resolver at 1.1.1.1 and 1.0.0.1. Cloudflare processes those DNS queries under Cloudflare's Privacy Policy and its 1.1.1.1 resolver privacy information.
Important limits of this feature:
- It is not a full VPN. It does not route your web traffic through a remote VPN server, does not encrypt your web traffic, and does not hide your IP address. Websites, ad networks and your internet provider can still see your IP address.
- We do not operate the DNS resolver and we do not receive or log your DNS queries.
- While Secure DNS is on, Android shows a persistent notification and the key icon in the status bar, because the feature runs as a foreground service. Turn it off in the App at any time to stop it.
6. Ad Block, Anonymity Shield and incognito tabs
- Ad Block filters requests to known advertising hosts inside the App's browser only; it does not affect other apps or the advertisements that support the App itself. To keep the filter current, the App downloads a public list of ad-server host names from pgl.yoyo.org (Peter Lowe's ad server list). That request reveals your IP address and standard connection information to that site.
- Anonymity Shield, when on, blocks screenshots and screen recording of the App and clears cookies and web storage when it is turned on or off. It does not hide your IP address or make you anonymous on the internet.
- Incognito tabs do not save browsing history in the App. Websites, your network, your internet provider and the SDKs described above can still observe your activity; files you download remain on your device until you delete them.
7. Pages and services you visit
When you open a website, your device communicates directly with that site, which is operated by a third party. That site may collect information, set cookies or show its own ads under its own privacy policy. We are not responsible for the privacy practices of websites, search engines or services you reach through the App. Search queries you enter are processed by your selected search engine (Google, Microsoft Bing, DuckDuckGo).
8. How we use information
- To operate, maintain and improve the browser and its features.
- To display and measure advertising that supports a free App, and to prevent ad fraud.
- To understand how the App is used, measure install sources and evaluate marketing performance.
- To detect, diagnose and fix crashes and technical problems.
- To protect the security and integrity of the App and to comply with legal obligations.
- To respond to your messages.
Where the GDPR applies, our legal bases are your consent (advertising identifiers and personalized ads, collected through the consent form), our legitimate interests (security, fraud prevention, crash diagnostics, service improvement), and, where applicable, performance of the service you requested.
9. Your choices and rights
- Ad consent: If you are in the European Economic Area, the United Kingdom or another region where it is required, the App uses the Google User Messaging Platform (UMP) to show a consent form before advertising identifiers are used for ads. You can accept, decline or later change your choice where the App offers privacy options.
- Advertising ID: On Android you can reset your Advertising ID or opt out of ads personalization in Settings (for example Settings > Privacy > Ads, or Google Settings > Ads, depending on your device). Opting out does not remove ads but stops their use of your advertising profile.
- Secure DNS, Ad Block and Anonymity Shield are off unless you turn them on, and you can turn them off at any time.
- Notifications: You can disable notifications in Android Settings.
- Rights: Depending on where you live (for example under the GDPR or the CCPA/CPRA), you may have the right to access, correct, delete or port personal data, to object to or restrict processing, to withdraw consent, and to opt out of the sale or sharing of personal information. Because we do not hold an account or a profile about you, most data relating to you is held by the third-party providers in Section 4; you can exercise your rights with them using the links above. You may also write to us at nguyenvankhanh.20061981@gmail.com and we will help or direct your request to the right party. You also have the right to lodge a complaint with your local data protection authority. We will not discriminate against you for exercising your rights.
10. Retention and deletion
Data stored in the App (history, bookmarks, tabs, downloads list, cookies, settings) remains on your device until you delete it. To delete it, open the Clear browsing data option in the App's settings, or uninstall the App, which removes the App's local data. Files you downloaded to your device's storage are separate and can be removed with your file manager.
Data held by Google, Firebase, advertising networks and attribution providers is retained under their policies and is not stored in a profile by us that identifies you. For other deletion requests, email nguyenvankhanh.20061981@gmail.com.
11. Security
We apply reasonable measures to protect the App and its communications, including HTTPS where the websites you visit support it. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.
12. International transfers
The providers listed in Section 4 operate globally, so information may be processed in countries other than yours, including the United States, with safeguards required by applicable law such as standard contractual clauses where applicable.
13. Children
The App is a general-audience browser intended for users aged 13 and over and is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information through the App, contact us at nguyenvankhanh.20061981@gmail.com and we will work with the relevant providers to address it. Because the App provides unrestricted access to the open web, parents and guardians should supervise minors' use.
14. Changes to this policy
We may update this policy from time to time. The "Effective date" at the top shows when it last changed. Material changes will be reflected in the App's Google Play listing or this page. Continued use after a change means you accept the updated policy.
