0x03 Contact
Ask us something. A person answers.
Questions about tickets, a talk or taking part? Choose an address below, or send the organising team a message. A volunteer will reply.
- Typical reply
- Within a week That is our aim, not a guaranteed response time. If you have not heard back after ten days, please follow up by email.
- General address
- [email protected]
- Conduct reports
- Not through this form They go to [email protected] instead, so the report reaches the restricted conduct mailbox rather than the general form. See the code of conduct.
01 The form
Tell us what you need.
Name, email, subject and message are required. A phone number is optional. Talk proposals belong on the CFP page, not in this form.
Where this goes
A Cloudflare Pages Function passes your message to Resend for email delivery to the organising team's configured mailbox. There is no separate form submissions dashboard. You can also write directly to [email protected].
The form itself sets no cookie and adds no tracker. Analytics are a separate question, and the privacy page says what they are.
How long we keep it
To be confirmed
We have not yet set a fixed retention period. Answering your question does
not automatically delete the message. See
the retention notice and
how to request deletion.
If you would rather not use a form
Use a direct address if you prefer your own email app and a copy in your sent folder. Conduct reports and private messages have their own routes below.
See the six addresses02 Direct
Six addresses, and one of them is enough.
The form is a convenience, not a gate. If you would rather keep your own copy of what you sent, write to one of these instead. This is a shortcut, not a filing system to learn.
General
Anything at all
The venue, travel, volunteering, villages, workshops, a broken link, and every question that does not obviously belong somewhere else. This is the address in the footer of every page, and the one to use when in doubt. We will pass it on.
Attending
Tickets and getting here
A ticket, a registration that went wrong, a refund, an access need, a letter confirming the conference for a visa, or an entry to the capture the flag. Ask early, particularly about access: an honest answer sometimes needs a walk around the building.
Speaking
The call for papers
Questions about a submission, the format, or a decision you have already had. Read by the review board rather than the general team, so it is also where to ask how a proposal was assessed.
Sponsorship
Partnering with 0x03
Tiers, the prospectus, what a partner does and does not get, and the free community tier for local groups and student chapters. The sponsors page answers most of it first.
Conduct
Reporting an incident
Read by the founding team and the team leads rather than by everyone with an organiser badge, and past them a report goes only to the people dealing with it. Use it during the event as well as after. You decide how much to say and what you want done about it. What happens next.
A person, not a list
The founder and lead organiser
Every other address here is a shared mailbox. This one belongs to the founder and lead organiser and is read by nobody else, which is the right choice if a shared inbox is the reason you would otherwise not write at all. It is slower, because it is one person.
03 Answered already
Five answers, so you can skip the email.
These are the questions we get most. If yours is here, you already have the answer, and if the answer is "not yet", that is the real answer rather than a holding reply.
-
Are tickets on sale?
Not yet. When they open they will be on KonfHub, starting at ₹999 for students with a valid ID, ₹2,399 individual and ₹5,299 company-funded. Those are the first-stage prices and they rise twice, so the tickets page has the whole ladder. Asking us will not get you an earlier link.
-
When does the CFP open and close?
It opens 25 October 2026 and closes 6 December 2026, with decisions by 15 January 2027. The CFP page computes which of those three it currently is, so it is never out of date. First-time speakers are explicitly welcome.
-
Where exactly is the venue?
It is a venue in Dehradun, to be announced, in Dehradun, Uttarakhand, India, a city that sits at 640 m / 2,100 ft above sea level. To be confirmed The venue, the gate and the room allocation go up as soon as they are signed off. Venue and travel carries the airport and railhead.
-
Can I run a village or a workshop?
Yes, and we would like you to. Running a village explains what a village is and what we provide; workshops go through the call for papers because they need a room and a slot. Pitch the idea before you build the material.
-
Who is sponsoring 0x03?
Nobody yet, and we will not pretend otherwise. Partners are announced from January 2027. Local groups, student chapters and nonprofits are listed free on the community tier. See the sponsors page.
Still not sure who to ask
Send it to the general address. We will find the right person.
A message in the wrong inbox is a two-minute forward for us and no trouble at all. A question you did not ask because you could not work out where it went is the only outcome worth avoiding.
