Privacy Policy
Veilo ("the App", "we", "us", "our"), operated by Tranquil Mind Technology JSC, respects your privacy. This Privacy Policy explains what information we collect, how we use and share it, and the choices and rights you have. By using the App, you agree to this Policy.
Veilo is a private web browser with a built-in free VPN: it routes your device's internet connection through an encrypted VPN tunnel and provides a browser to access the open web. You do not need to create an account to use it, and the App does not ask you to sign in.
1. Information We Collect
We do not require you to provide your name, email, or other personal contact details to use the App. We do not ask for camera, microphone, contacts, calendar, photos, or precise-location access.
Information collected automatically
When you use the App, our service providers and advertising partners may collect:
- Device and advertising identifiers — including your Google Advertising ID (AAID) and app-instance / installation identifiers, used to serve and measure ads and to detect invalid traffic.
- Approximate location — coarse location derived from your IP address by our advertising partners for ad targeting and measurement. We do not collect GPS/precise location.
- App activity — in-app interactions and events (such as ad views, screens used, and which features you tap), used for advertising and to operate the App.
- Crash logs and diagnostics — crash reports, error logs, and performance/diagnostic data used to keep the App stable.
- Network / connection information — technical data needed to establish the VPN connection (for example your originating IP address, chosen server, and connection status). Your device's public IP address is sent to a third-party IP-lookup service (ipify) so the App can display your real IP and help verify VPN status; the App also downloads its list of free VPN servers from VPNGate (a third-party volunteer VPN network) and connection-configuration files from our servers and community-operated mirrors. As with any internet request, these requests carry your IP address, but they are not linked to your name or an account and no advertising identifier is attached to them.
Information stored only on your device (not collected by us)
The following stay on your device and are not transmitted to us: your browsing history, bookmarks, tabs, and search-engine preference, and app settings. Incognito tabs do not retain history, and you can clear your browsing history at any time in the App.
2. How We Use Information
We use the information above to:
- Provide and operate the App, including establishing and maintaining the VPN connection and the built-in browser.
- Display advertising (including, where you consent, personalized advertising) and measure its performance.
- Detect, prevent, and address fraud, abuse, invalid ad traffic, and security issues.
- Diagnose crashes and improve the stability and performance of the App.
- Comply with legal obligations and enforce our Terms.
We do not use your data to make automated decisions that produce legal or similarly significant effects about you.
3. Third-Party Services

4. How We Share Information
We do not sell your personal information for money. We share information only:
- With the third-party service providers and advertising partners listed in Section 3, for the purposes described.
- For legal reasons — to comply with law, regulation, legal process, or enforceable governmental request, or to protect rights, safety, and property.
- In a business transfer — as part of a merger, acquisition, financing, or sale of assets, subject to this Policy.
5. Legal Bases (EEA/UK — GDPR)
Where the GDPR or UK GDPR applies, we rely on: consent (for personalized advertising and any processing that requires it); legitimate interests (operating the App, security and fraud prevention, and improving stability); and legal obligation (responding to lawful requests). You may withdraw consent at any time.
6. Data Retention
We and our providers retain information only as long as necessary for the purposes described or as required by law. Advertising and analytics identifiers are retained according to each partner's retention schedule; crash and diagnostic data are retained for a limited period to investigate issues. Data stored only on your device (browsing history, bookmarks, settings) remains until you clear it or uninstall the App.
7. Your Rights
Depending on where you live, you may have the right to access, correct, delete, port, or restrict processing of your personal data, to object to processing, to withdraw consent, and to opt out of the "sale"/"sharing" of personal information or targeted advertising. EEA/UK users may also lodge a complaint with their data protection authority. Residents of other regions (e.g. LGPD in Brazil, PIPEDA in Canada) have comparable rights.
Because the App has no accounts, we may not hold information that identifies you by name. To exercise a right, contact us at the email below and, so we can locate any relevant data, include your device advertising ID and relevant details (device model, approximate date/time of use).
8. Children's Privacy
The App is intended for users 13 years of age and older (or the higher minimum age of digital consent in your country) and is not directed to children under that age. We do not knowingly collect personal information from children. If you believe a child has provided us information, contact us and we will take appropriate steps to delete it. Parents and guardians should note that the built-in browser can access the open internet; consider supervising younger users accordingly.
9. International Data Transfers
Your information may be processed in countries other than your own, including the United States, where our service providers operate. Where required, we and our providers use appropriate safeguards (such as the EU Standard Contractual Clauses) for these transfers.
10. Data Security
Data transmitted by the App and its SDKs is protected in transit using industry-standard encryption (HTTPS/TLS), and the VPN connection itself is carried over an encrypted OpenVPN tunnel. However, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security. A VPN increases privacy but is not absolute anonymity.
11. Third-Party Content
The built-in browser lets you access websites and content operated by third parties. We do not control and are not responsible for third-party content, sites, or services, or their privacy practices. Please review the policies of any site you visit.
12. Changes to This Policy
We may update this Policy from time to time. Material changes will be posted here with a new "Last updated" date. Your continued use of the App after changes take effect constitutes acceptance.
