Keep your data private with WireDog VPN – a US-based, open-source, no-logs VPN service. Plans start at $6.99/month with annual billing. GETTING STARTED 1. Install the app. 2. Create a Standard (Email/Password) or Anonymous (16-digit account number) account. 3. Purchase a subscription via in-app purchase, or on our website. 4. Connect with one tap. Your data now routes exclusively through U.S. infrastructure. PRIVACY FIRST COMMITMENT - WireDog has a strict zero-logs policy on your VPN activity. - WireDog is committed to transparency by remaining open-source. - We don't collect browsing history, websites visited, DNS queries, traffic contents, or IP addresses. - Anonymous accounts use a 16-digit account number only, maximizing your anonymity. - All data stays within U.S. infrastructure, so your data never leaves U.S. soil. HOW WIREDOG VPN WORKS When you connect to WireDog, your internet traffic travels through an encrypted tunnel to one of our U.S. servers. Websites and services only see our server's identity, not yours. Your internet service provider (ISP) can see you're using a VPN, but not what you're doing. WireDog never logs activity, so we can't provide it to anyone – even under legal request. This is possible because of our privacy-first architecture. We're open-source, so you can verify our claims. WHY PRIVACY MATTERS Your online activity is yours alone. WireDog is built to protect you from data collection, surveillance, and tracking. We don't sell your data. We don't profile you. We don't monitor what you do online. You can learn more about our Privacy Policy and Terms of Service here: https://www.wiredogvpn.com/legal/privacy https://www.wiredogvpn.com/legal/terms-of-service

The only scanner that solves a Samurai. Point your camera at a printed Sudoku and get the solution. Not just the standard 9×9 — Sudoku Solver reads the five-grid Samurai too, the one no other scanner will touch. HOW IT WORKS Hold your phone over the puzzle. It finds the grid, reads the digits, and works out the answer — usually in about a second. Nothing to type in, nothing to line up. IT TELLS YOU HOW, NOT JUST WHAT Every solution names the techniques the puzzle actually needed — naked singles, hidden pairs, X-Wings — so you can see where you were stuck. Want to work through it properly? One tap opens the exact board in Samuraiku and walks you through it step by step. SHARE THE ANSWER Send or print a clean solution card with the original clues in bold, so you can check your own work against it. WHAT IT DOESN'T DO No ads. No subscription. No account. Nothing is uploaded — the camera image never leaves your phone, and it's never saved to your photo library. You pay once. Classic 9×9 and Samurai. Works offline. Made by the people behind Samuraiku.
