Your address stays yours
Customers get eight characters. The server behind it is never
shown to them, printed on anything, or recoverable from the code.
Nothing to re-issue
Everyone who already has the code follows automatically, with
nothing to reinstall and nothing to retype.
Off means off
Switch a code off and it stops resolving within a minute. A revoked
code and one that never existed look identical from outside.
No one is counting your customers
We keep a daily total per code so you can see it is being used.
We do not keep a record of who used it or when.
A single code works alongside your other single codes: someone can
add two of them in the same app and see both servers together.
A group is five codes meant to be used as one set. They work with
each other and not with anything else, so a customer holding one of your group codes
can add the rest of the group but cannot mix in a code from elsewhere.
Apps enforce this and explain it to the person, so nobody is left
wondering why a code was refused.
What does it record about the people who use my codes?
A daily total per code, so you can see it is being used, and nothing else. There is no log of who looked a code up or when, so we cannot tell you or anyone else. To stop people guessing codes, wrong guesses are limited using a hashed form of the address they come from, never the address itself.
How is the server address behind a code protected?
It is encrypted (AES-256) before it is stored, with a key that is not kept in the database, so a copy of the database on its own shows nobody's server. Only apps we have approved for access, such as Vizi Player, can look it up, and Vizi Player uses it to connect without ever showing it. A code that is mistyped, switched off or expired gets exactly the same answer as one that never existed. The address is private rather than secret: the device still connects to it.
Can I change where a code points after I have bought it?
Yes, yourself, free, at any time. Sign in, open My codes, press Change destination beside the code, enter the new server address and save it. It takes effect on the next check, and nobody using the code has to do anything. There is no charge and no limit on how often.
Can LinkACode see my username, password or anything I play?
No. A code stands for a server address (a host, and a port if it has one) and nothing else. The username and password go from the app straight to the server, never to us, and nothing you play passes through LinkACode.
Whose server can a code point at?
Yours, or one you are authorised to use. A code is a shortcut to an address you already have the right to connect to. It does not come with content, and it does not give you access to anything you could not already reach.
Apps can take a LinkACode code from the person using them and get the server behind it
from us, so your users type eight characters instead of an address and never retype it when
the seller moves.
Access is granted case by case and priced on how many calls your app makes. Tell us what
you are building and we will come back to you.
