Privacy, in plain language.
This page explains information used to operate the updated BestLine VPN app and the privacy and contact choices available to you.
Last updated: November 8, 2026
Operating the app
VPN operation uses IP addresses, which can indicate approximate location, basic device information, installation identifiers, pseudonymous provider account IDs and connection requests. These support accounts, sessions, available locations, service operation and security.
Automatic service settings
We use Firebase Remote Config to deliver service settings. Requests may include an installation identifier, IP address, and app/device information. We do not use this feature for personalization, and VPN account credentials are not included in these configuration requests.
External VPN service
VPN connectivity uses an external VPN service. The service receives IP addresses, device information and connection requests for operation and security. Provider handling of DNS or browsing data, retention periods and deletion scope are not confirmed.
What stays on your device
Appearance, language and app-selection preferences stay on your device. Account details needed for operation are kept in protected app storage, with account data encrypted. Clearing Android app storage removes these local records.
Ads and your choices
Google AdMob may process advertising and device identifiers, IP-derived approximate location, app interactions such as ad views or clicks, and diagnostics for advertising, measurement and fraud prevention, depending on settings and required consent. Available ad privacy choices can be opened from the app menu.
Crash diagnostics
Firebase Crashlytics sends crash and session diagnostics to improve stability, including native crashes, app state, device and operating-system information, and installation or session identifiers. Firebase states that crash traces, extracted native-crash data and associated identifiers are kept for 90 days before removal from live and backup systems begins.
Protecting app requests
We use Firebase App Check with Google Play Integrity to verify app requests and help prevent abuse of subscription verification. Google processes app and device integrity signals, attestation data and verification tokens; App Check tokens accompany requests to the protected service. Google services may also process technical request information, including IP addresses, and maintain operational and security logs.
Subscriptions and purchase verification
If you buy or restore an ad-free subscription, purchase details and history, including a Google Play purchase token, are processed to verify it. The app sends the token to our Firebase verifier, which checks the product, plan, status and expiry with Google Play and acknowledges valid purchases when needed. Our verifier does not send the token to the VPN provider or keep a purchase-token database. Google handles Play purchase records under its own policies.
Contacting us
If you email support, we receive your email address and the messages you choose to send to handle your request. We review requests to remove support correspondence manually. Do not send passwords, payment details or unnecessary private logs.
Retention and deletion requests
Retention and deletion depend on the data and the service holding it. Clearing local app storage does not delete provider or Google Play records, or cancel a subscription. Request deletion through our data deletion page or support email. We may need to verify the request and identify records we control; other providers have their own terms and procedures.
