12. Using the work of others.
If you are developing something that is based on the work of another Member, you MUST first seek their permission, and you must give credit to the member whose work you used. If a dispute occurs about who developed / created a piece of work, first try to settle the matter by private message and NOT in open forum. If this fails then you may contact a moderator with clear evidence that the work was created by you.
Convincing evidence will result in copied work being removed. If there is no clear evidence you created the work then in the spirit of sharing all work will remain posted on the forums.
As an addition, developers have the right to hold exclusivity over their work for as long as it is deemed necessary by the dev or freely share it. However, if the work is claimed as exclusive, it must remain as such. No selective sharing will be allowed (ie allowing certain people to use it and not others). Should the dev decide to start sharing the work with others, the work automatically becomes fair game for all to use.
In regards to permissions, same rules remain for this but if permission was already given, unless there is a very valid reason, it cannot be revoked (same applies to major updates on the work). Under that same premise, permissions cannot be denied unless the work is exclusive or under severe circumstances.
In plain English: If you want to keep your work exclusive, go for it. However, if you are going to share your work, do it fairly.
These rules apply to all software posted on XDA (including but not limited to ROMs, RUUs, apps, games, kernels, themes, icons, etc) unless that software comes with a license that waives these rules.
