Flow is a DNS privacy app for iPhone and iPad. It encrypts every DNS query your device makes — preventing your carrier, ISP, and anyone on your network from seeing which websites and services you use. WHAT DNS IS AND WHY IT MATTERS Every time you open an app or visit a website, your device first asks a DNS server to translate the address into an IP. By default, this request is sent unencrypted — visible to your carrier, ISP, and anyone monitoring your connection. Flow replaces this with DNS-over-HTTPS (DoH) or DNS-over-TLS (DoT), encrypting every query so only the provider you choose can read it. HOW IT WORKS Flow installs a secure DNS profile directly on your device. Once active, every DNS request — every app, every website, every service — is encrypted before it leaves your iPhone or iPad. No VPN. No app that needs to stay open. No extra battery drain. 16+ PROVIDERS TO CHOOSE FROM • Cloudflare 1.1.1.1 — fastest public DNS, strict no-logging policy • Quad9 — blocks malware and phishing domains automatically • AdGuard — removes ads and trackers at the DNS level • NextDNS — fully customisable filtering rules • Mullvad — privacy-first, no logs, Tor-compatible • Google, OpenDNS, CleanBrowsing, Control D, and more Switch providers in seconds. Or add your own custom DoH or DoT server. FLOW+ — PAY ONCE, OWN IT FOREVER Flow+ unlocks the full experience with a single payment. No subscription. No renewal. No catch. Flow+ includes: • All privacy and ad-blocking providers • Custom DNS profiles — save up to 3 configurations • Auto-switch by network — different DNS per Wi-Fi • DNS Benchmark — find the fastest provider for your connection • DNS Health Check — resolution, latency, leaks, DNSSEC • Disconnect alerts — get notified if your profile goes offline • Siri & Shortcuts — pause, resume, switch providers by voice • Themes and accent colours • iCloud sync — settings follow you across all your devices • Lock Screen and Home Screen widgets YOUR PRIVACY Flow has no servers and no analytics. It does not log, collect, or sell any information about your DNS activity or browsing. The provider you choose handles your queries according to their own privacy policy — check it before you pick. Requires iOS 16 or later. Compatible with iPhone and iPad. ______________________________ IMPORTANT Privacy Policy: flowprivacy.rift.lat Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
