You can not change the encryption method because using the wrong encryption method will make the service unusable, among other potential risks.
We strive to make Accelkey simple and easy to use, so we prohibit users from modifying the encryption method themselves.
Currently, we set all users to use the AEAD algorithm (Chacha20-IETF-Poly1305 cipher).

Yes, most of our servers already support IPv6.

We are unable to implement TFO for the entire connection link (from user client to target access server), due to the fact that most servers in the world do not support TFO, which makes enabling this feature very limited at this time.

The transfer quota is the maximum amount of traffic you can use each month.

Yes. Based on the start date of your subscription, it will reset monthly until the end of your subscription.

No, but you can repurchase a subscription with higher transfer quota. The remaining time of your current subscription will be automatically discounted.

Yes, you just have to repurchase the subscription you want.
The remaining time on your current subscription will be returned as an account balance, which will be used first when you pay for a new order.

Traffic rate (also called "Rate") is the rate at which the server consumes traffic.
×1 means that the server traffic is calculated according to your actual consumption, ×2 means that the server traffic is calculated according to 2 times the actual consumption.

Yes, but Accelkey is not specifically optimized for games, so you may not get the best experience.

We grant our users the possibility of a 100% refund of the purchase price of Accelkey annually subscriptions purchased from https://accelkey.com/ (for subscriptions purchased elsewhere, please check the refund policy of that particular reseller). For annually subscriptions, we have a 30-day money-back guarantee. All refund requests for annually subscriptions made within 30 days of the purchase date are granted no matter what the reason is. The subscription in question is rendered inactive the moment the refund is issued.
After 30 days, all requests are assessed individually, and the decision of whether to issue a refund resides with Accelkey. We do not grant partial refunds for subscription upgrades and renewals. Each case of a partial refund request is discussed separately between Users and Support and granted only upon mutual agreement. To get a refund for a annually subscription purchased on the official website https://accelkey.com/, please contact our support team: [email protected].
Processing time will depend on your choice of payment method but usually it takes between 7 and 14 business days.

You will need to log in to Accelkey Dashboard and renew your subscription manually.

Based on the principle of fair use of resources, you may not share your subscription with others.
Accelkey is restricted to the account holder's own use.

We do not recommend you to do this, because the subscription cannot be transferred to another account.

There is no limit to the number of devices.
