Credits

Is there a free trial version of Mudfish I can use?

No. However when you verify your email, small amount of Mudfish test credit is funded into your account. It'll be delivered to your inbox when you first sign up.

How can I get Mudfish test credit?

It's automatically funded into your account when your email is verified.

How long would it take to consume $2.99 credits?

Frankly speaking, I don't have answer for this question because it depends on your plan and depends on how you use Mudfish.

For example if your data plan is Subscription and have 4-1 voucher (cost is 990 KRW), it'll last for 3 months. But if your data plan is Pay-Per-Traffic, it could be longer than 6 months or shorter than 1 month depending on your traffic usage.

When does the mudfish credit expire?

Never happen. :-) Even if you don't have time to play with Mudfish for years, you don't need to worry.

I don't want to be auto billed for service!

You don't need to worry about it. At Mudfish, it doesn't have a concept 'auto billed' at all. Mudfish Credit is only funded when user buys it on demand.

I bought mudfish credits but it charges additional 1 USD charge!

That's because the $1 charge is actually a temporary preauthorization from your credit card company, basically giving the merchant the green light to charge your card for the full amount when your final purchase is made.

So you don't need to worry about it because it'll be automatically cancelled within few days normally.

I bought $3 USD mudfish credits. How long can I keep playing the game?

Frankly speaking, I don't have idea. It'd be very vary depending on your traffic patterns. At current rate (01/20/2016), 135 KRW (South Korean Won) per 1 Gbytes is general a price table and $3 USD is about 27 Gbytes by current exchange rate.

If your data plan is Pay-Per-Traffic, you can play the game with Mudfish until all traffics are gone.

How to pay for this, I don't have paypal.

Available methods depend on your payment currency. See Pricing for the supported options, or open the credit purchase page and try another currency if your preferred method is not listed.

Check the purchase page for available payment methods and amounts.

Verified email, but there's no free credit for me to test the service.

Oops. Sorry for this inconvenience that sometimes it's not added properly due to double-credit-payments protection algorithm. Please create a topic for this issue at dashboard. We'll handle it for you.

What is the difference between the credit balance and traffic balance?

Frankly speaking, it's same. It's simply to show information how many traffics are available with current credits.

A little Mudfish Credit is charged even if I'm not playing the game!

This symptom is very normal because Mudfish Credits are charged based on how many you used the traffics. It means that even if you didn't play the game (just turning on Mudfish), the traffic could be used because:

• your Mudfish client connects with our VPN servers and sends small heartbeat packets every three minutes to keep the connection alive.

• Mudfish's network is based on Layer 2 of OSI (Open Systems Interconnection) indicating ARP and Broadcasting packets could be transferred from your desktop to VPN server or from VPN servers to your desktop.

Please note that the charged amount of Mudfish Credit would be very small and usages of traffic are always checkable at "Account Management" (http://accounts.en.loxch.com/) by visiting 'Accounts → Traffic Usage'.

However if usages of traffic are abnormal, please make sure that your account is kept safe and Full VPN is off. Restart Mudfish after disabling Full VPN so the change takes effect.

Does it consumes credits if I use browser (stuff like youtube and such) with mudfish open?

If Full VPN mode is on, browser traffic and uploads count toward credit usage. Otherwise, only traffic matching your equipped game or website items is routed through Mudfish and charged.

Can I stream my game on Twitch or YouTube while using Mudfish?

Yes. Streaming traffic uses Mudfish credits if Full VPN is enabled or if that traffic matches an equipped item.

Why my traffic get wasted while I am sleeping?

This has a history of Mudfish. When I first released Mudfish package with pay-per-traffic data plan, it doesn't consume much CPU and memories of master server to calculate all user's traffic bytes and charges a mudfish credit in real-time. But it was getting worse and more worse whenever total no. of users are increased and finally it affects all service quality of master server. At 8/15/2015 I'd re-implemented the traffic handling code and changed the default policy as follows:

• Master server tries to aggregate as many as it can for user's traffic bytes to reduce CPU load and memory usage.
• Actual credit charges could be delayed up to 1 ~ 2 hours after terminating Mudfish Launcher. Most of them are handled within half a hour after stop of Mudfish.

How to verify my traffic usage?

If you'd like to verify the traffic usages of Mudfish, you should explicitly enable "Connection Log" which is found under "Account → Edit Profile" menu. Its default is off to protect yours' privacy.

See Data Plans for current plan details.

However please note that at "Status → Access Log" menu only show traffics whose input / output bytes are larger than 1 Mbytes. If you'd like to see full access logs, please visit http://accounts.en.loxch.com/ link.

Does using advanced mode (2 nodes) consume traffic twice as basic mode?

No. It still consumes same cost.

If I buy mudfish credit from google play store, can I use that same credit to play desktop games?

Yes. It's same and connected each other.

My traffic balance is changing even if I didn't use Mudfish for a while

If your currency is one of USD, AUD, JPY and CNY for your Mudfish account, the traffic balance could be changed depending on the exchange rates between your currency and KRW because the traffic balance is calculated based on KRW.

If you want to keep the fixed traffic balance, you need to change your currency to KRW.

When are credits deducted on Pay Per Traffic?

Credits are deducted according to the amount of traffic you send and receive and the selected node's rate. Available traffic is an estimate derived from the remaining balance; the documented base rate is 135 KRW per GB. Foreign currency estimates also depend on exchange rates, as explained above.

On the Subscription plan, credits are deducted once when you purchase the item or voucher, rather than according to traffic usage.

How long will 5 GB last?

It depends on the game's traffic pattern. Low-traffic games can use the same balance much longer than high-traffic games. With careless Full VPN use, traffic from downloads or other applications can exhaust credits within days. The older $2.99 and $3 examples above illustrate usage patterns; consult Pricing for purchase amounts.

Why does the displayed balance change in tiny increments?

Credits are stored internally with double precision, while the interface shows four decimal places. Rounding and aggregation can cause tiny visible changes, in addition to heartbeat and broadcast traffic.

How can I investigate a large, unexpected deduction?

Connection logging is off by default for privacy, so past unlogged usage cannot be reconstructed from access logs. Enable “Connection Log” in “Account → Edit Profile”. Records begin accumulating from that point; inspect them under “Status → Access Log”. See Reading access logs.

Also check whether Full VPN is still enabled or whether someone else is using your account.

An equipped item may also have a CDN or cloud traffic warning on its settings page. Read that warning carefully: traffic unrelated to your game can match the item's routes and consume credits.

What happens if my credit balance becomes negative?

A negative balance means you used more credits than were available. You can no longer connect to paid nodes on the Pay Per Traffic plan. When you next buy credits, the negative balance is deducted from the amount added to your account.

A Korean direct bank transfer has not been credited after 24 hours.

Check whether you sent it to the designated Kookmin Bank account rather than a Toss account, and check the name shown to the recipient. An unexpected name or a label such as “Mudfish”, “VPN” or “Credits” can prevent staff from matching the payment to your account.

Post or reply on the Mudfish forums, including the transfer date and time, so staff can identify it.
