Our service works on Windows, macOS, iOS, iPadOS, Android, Linux, and routers. You only need 1 account for universal use on all devices.

Great question! First of all, we provide a paid service, so we do not need your private data to stay operational. We only collect the most minimal data required to keep the service healthy and operational. Storing your data can be more expensive than you think. In order to provide service properly, we need to know your email address, and if you bill in EUR/USD, we also need your billing address to calculate the VAT. When you make a payment, we record the e-wallet account ID that you used to make the payment (we have no way of knowing your e-wallet account information through this ID) and we need to record this information to prevent payment fraud. When you use the service, we record the IP address, time, amount of data consumed, and the unique identifier of the device used for our statistics; unique identifiers do not carry any personal information. We do not store what websites you visit. Unless you explicitly ask us to do so: sometimes some customers want to know where their traffic is going. All the data we obtain is for our records only and will not be made available to third parties. When requested by authorities with law enforcement powers over us (e.g. tax authorities), we will provide the relevant authorities with the information required by law (e.g. your billing address).

Your online security may be divided into data security and communication security. Our service is responsible for the security of your communications, as well as ensuring that the data we collect about you is stored securely. Communication security: our protocols all run in SSL and encrypt all communications using 256-bit keys, which would take millions of years to crack, even using Tianhe 2, so your communication security is guaranteed. Data security: all our data is stored on the hard drive using the same level of encryption, so even if the storage medium is taken away, the original file contents cannot be read. However, the above does not completely guarantee that your data is absolutely safe, security requires you to always be on the lookout for yourself, and if you give out private information on a phishing website, then no one can help you. You got the idea :P
