Contact
There is one inbox, and a person reads it.
No ticket queue, no chatbot, no contact form that swallows what you wrote. Pick whichever section below describes your question and say what happened; the more specific you are, the shorter the exchange.
Support and anything about the product
Something broken, something confusing, something missing. Include your workspace name and, if a specific post or connection is involved, a link to it. If you hit an error screen, the ten-digit reference on it resolves to the exact failure and saves a round trip.
Email supportSecurity
If you have found a vulnerability, write before you go any further and say what you have found and how you found it. Testing in good faith against your own workspace is welcome and is not a breach of the acceptable use policy when you have told us first. Reports are read the day they arrive.
Report a vulnerabilityPrivacy and data protection
Access, correction, deletion, portability, objection, or a question about the data processing agreement. Say which right you are exercising and which workspace it concerns. If your request came through Facebook, the status page for it is linked below.
Email about dataBilling and invoices
A charge you do not recognise, an invoice you need reissued, a VAT number to add, or a plan that is wrong for you. Most of this is faster from the billing screen inside the product, and anything that is not comes here.
Email about billingPress, partnerships and everything else
There is no press office. Questions about the product, the market or the numbers are answered by the person who built it, which usually makes for a better answer and occasionally a slower one.
EmailThe address
Where the mail goes.
Every route above reaches hello@crestnote.com. There is one address because five on a company of this size means four of them are not being watched, and the one nobody watches is always the security one.
The business behind it is DEVIORA S.R.L., a limited liability company of Calea Șerban Vodă 282, Sector 4, București 040221, Romania, CUI 55471145, Reg. Com. J2026051139003, share capital 500 lei. The telephone is +40 725 680 625, and it reaches the same person the mailbox does. The same details are on the privacy policy, and the about page says what that means in practice.
Replies usually come the same working day and sometimes the next. There is no support contract behind that and this page does not pretend there is one.
Faster elsewhere
Three things you do not need us for.
Deleting your data
Deleting a workspace removes its content, media, connections and history. If you started a deletion from inside Facebook, the status page tells you where it got to, using the confirmation code Facebook gave you.
Cancelling
From the billing screen, in the same number of clicks it took to subscribe. There is no retention call and nothing to email. The workspace drops to the free plan and stays open.
Knowing what changed
The changelog lists what shipped and when, including the fixes and not only the features.
