ShieldFlow Privacy Policy
Last updated: 2026-09-30
ShieldFlow is a VPN service. We respect your privacy and collect the minimum data needed to provide the service.
What data we process
A technical app-installation identifier, ad-session timing, and any diagnostics you choose to send to support. We do not ask for your name, ID documents, or precise address.
Product analytics
To improve onboarding, connection reliability, retention, and the referral program, we record technical product events: installation and daily app opens, rewarded-ad presentation and completion, first VPN connection, reaching 10 minutes of VPN use, and opening, sharing, redeeming, or completing a referral. Events may include the randomly generated app-installation identifier, event time, app version and build, system locale, and the selected VPN server.
We also receive impression-level advertising revenue metrics from Appodeal, including revenue amount in USD, ad format, placement, demand source, and measurement precision. ShieldFlow stores these events on its backend and uses them only in aggregate to measure the product funnel, D1/D7 retention, advertising revenue, and 7/30-day LTV. These events do not contain visited websites, DNS queries, VPN traffic contents, precise location, name, or email, and ShieldFlow does not sell them.
We also record connection attempts and their outcomes, broad failure categories, repeat connections, and a successful connection after an inactivity reminder. In iOS app version 0.68.7 and later, one reminder after seven days without use is enabled by default when notifications are allowed in iOS Settings. In earlier versions that offered this feature, it required a separate opt-in. The reminder is scheduled only on your device and does not connect the VPN automatically. You can disable ShieldFlow notifications in iOS Settings. These events do not contain raw error messages or browsing activity.
Traffic logs
We do NOT log your activity: we keep no history of visited sites, DNS queries, or traffic contents. VPN nodes are configured without connection logging.
Advertising in the mobile app
Free access in the ShieldFlow mobile app is funded by ads. Our advertising partners and related analytics services are:
• Appodeal (Appodeal, Inc.) — advertising mediation platform that runs a real-time auction across the demand sources below and may itself process the technical data listed here — privacy policy;
• Google AdMob (Google LLC) — privacy policy;
• Yandex Advertising Network / Yandex Mobile Ads and the AppMetrica analytics service (Yandex LLC) — privacy policy;
• AppLovin (AppLovin Corporation) — privacy policy;
• BidMachine — privacy policy;
• Unity Ads — privacy policy;
• Mintegral — privacy policy;
• Liftoff Monetize (Vungle) — privacy policy;
• Digital Turbine / DT Exchange (Fyber) — data processing terms;
• InMobi — privacy policy;
• VK Ads / myTarget (VK LLC) — privacy policy;
• myTracker (VK LLC, analytics SDK bundled with myTarget) — EEA/UK/Swiss policy, other regions;
• Unity / ironSource — privacy policy;
• BIGO Ads — privacy policy.
These partners may independently process technical device data to select, show, and measure ads: the device advertising identifier (IDFA/GAID), IP address, device model, OS version, system language, and ad-interaction data, governed by each network's own policies. Ads are shown before the VPN connection is established or within the app interface; ad networks do not get access to the contents of your VPN traffic.
These SDKs may also process app-usage and ad-event data, including app interactions and purchase events if they occur, for ad delivery, measurement, analytics, attribution, and fraud prevention. The data processed depends on the enabled network, region, device permissions, and your choices. On iOS, the app checks Apple's tracking permission before starting Appodeal; where required, Appodeal may present a consent form, and the app shows ad privacy options in Settings for later review.
Payment data
Paid unlocking of iOS app features is not available on the website. If paid digital features appear in the app in the future, they will be handled through App Store mechanisms.
Sharing with third parties
Apart from the advertising partners listed above, we do not sell or share your data with third parties, except where directly required by law.
