Terms of service
Last updated October 20, 2026
These terms are an agreement between you and Resonance Research LLC, a Delaware limited liability company ("we", "us"), which runs Codecember. By signing in you agree to them, to the Content policy and to how we handle your data as described in the Privacy policy.
What Codecember does
Codecember is a December event to write code every day. You sign in with GitHub, GitLab or Codeberg. We use read-only access to your account to read commit metadata (counts, lines changed, languages and commit hashes, never the code itself) and show your progress. You can add a note and an image to each day and create share links that show a day to anyone who has the link. Share links can be made until 30 days after an event ends. We never change your repositories.
Who can use it
You must be at least 13 years old to use Codecember. If you are under the age of digital consent where you live (up to 16 in some EU countries), you need permission from a parent or guardian, who agrees to these terms for you.
Your account
Your Codecember account is created when you first sign in with GitHub, GitLab or Codeberg, and you can connect more than one of them. Keep those accounts secure: anything done while signed in to your Codecember account is your responsibility. You must follow the rules of the provider you sign in with.
Your content
Your notes and images stay yours. To run Codecember you give us a worldwide, non-exclusive, royalty-free licence to host, store, process (for example resize or re-encode images) and display them inside Codecember: to you, and to anyone who opens a share link you created. The licence ends when you delete the content or your account, or when its hosting period ends, except for copies in backups, which are removed as the backups expire.
- We don't feature your work in our own posts, recaps or promotion unless we ask you first and you say yes.
- We never sell your content, never license it to anyone else and never use it to train AI.
You are responsible for what you post and must have the right to post it. Shared notes and screenshots can expose secrets such as tokens, keys, passwords or private data, so check them before you share a day. Anyone with a share link can see that day until you stop sharing it. Notes and images are hosted until 2 years after their event ends, then deleted. After that a share link shows only the day's stats, until you stop sharing it, which still deletes it.
What you can't post
Content and behaviour that breaks the Content policy is not allowed. You must not misuse the service: no attempts to break or overload it, get at other people's data, or get around a suspension or ban.
Copyright
If you believe content on Codecember infringes your copyright, send a notice to our designated agent: [DMCA agent: coming soon] . Include:
- the work you believe is infringed;
- the link to the content on Codecember;
- your name, address, phone number and email address;
- a statement that you believe in good faith the use is not authorised by the owner, its agent or the law;
- a statement, under penalty of perjury, that your notice is accurate and that you are the owner or authorised to act for them; and
- your physical or electronic signature.
We remove or disable the content and tell the person who posted it. If you posted it and believe it was removed by mistake, you can send a counter-notice to the same agent with the content that was removed, a statement under penalty of perjury that it was removed by mistake or misidentification, your name, address and phone number, your consent to the jurisdiction of the federal courts for your address (or, outside the US, any district where we can be found), and your signature. Unless the person who complained tells us they have filed a court action, we may restore the content 10 to 14 business days later. We end the accounts of repeat infringers.
Ending your account
You can delete your account at any time from Settings. This deletes your data as described in the Privacy policy.
We can remove content, suspend accounts or end accounts that break these terms or the Content policy, or where the law requires it. Where the law requires it, we tell you what we did and why, and how to object.
Disclaimer and liability
Codecember is free and provided "as is" and "as available", without warranties of any kind, to the extent the law allows. It may change, have downtime or lose data, so keep your own copies of anything important.
To the extent the law allows, we are not liable for indirect, incidental or consequential loss, or for loss of data, profits or goodwill. Nothing in these terms limits liability that cannot be limited by law, such as for death or personal injury caused by negligence, or for fraud.
Governing law
These terms are governed by the laws of the State of Delaware, United States, and disputes go to the state or federal courts in Delaware. Resonance Research LLC is a Delaware limited liability company.
If you are a consumer in the European Union or the United Kingdom, you keep the protection of the mandatory laws of the country you live in, and you can bring a claim in the courts of that country.
Changes to these terms
We may update these terms. We announce material changes on the site before they apply, and the date at the top of this page shows when they last changed. If you keep using Codecember after a change applies, the new terms apply to you; if you don't agree, you can delete your account.
