← Back to the vaultThe Vault is made and maintained by one person. There is no support desk and no ticket system — mail reaches a human directly, and gets answered.
Disputing a puzzle
The one thing we genuinely want to hear about. A vault code is supposed to have exactly one defensible order — if you believe a decoy produced a second reading that works just as well, that is a design bug and we would rather know. Include the vault number and the arrangement you think also holds up.
Bugs and rendering problems
Emoji render differently across devices, and a symbol that shows as an empty box can make a day unsolvable. If that happens, tell us your device and browser along with the vault number.
Privacy requests
Data-protection requests go to the same address and are answered within 30 days. Worth knowing first: your progress lives only in your own browser and we hold no server-side copy, so for most requests there is genuinely nothing on our side to retrieve or delete. The privacy policy sets out what that means in detail.
Lost progress
We can't restore a streak or a collection. Not as a policy — we simply never had a copy. See the FAQ for why.
