Rules for uploading addons
These are the rules that are shown before your first upload. Your addon has to follow these rules if you want to upload it to this website. If your addon fails to follow any of these rules, it will not be allowed on the website.
English Description
All uploaded files must contain at least a description written in English. Items without English description will be disabled.
Converted Aircraft or Scenery
Do not upload converted aircraft without the model owner's permission - no matter if freeware or not. Please respect the copyright laws. Even if the original creator shared it for free, it does not automatically allow you to redistribute it. You must be able to proof that you have the legal permission to use assets from another developer.
Donationware
All files must be completely free of charge. Offering updates or exclusive features against payment is not allowed. You may ask for donations, but you may not pair it for anything in return. Read more.
Add-Ons for pirated content
Flightsim.to respects developers. Uploading liveries for illegally converted aircraft is not permitted - which includes aircraft which can only be found on illegal or untrusted websites.
Copyrighted content
It is your sole responsibility to ensure that you own all necessary rights and licenses to your uploaded file, namely, you don't infringe anyone else's rights. If we receive a complaint, we may have to remove your file in accordance with our DMCA policies.
No Guides or Tutorials
Flightsim.to is dedicated to share add-ons and mods to expand the game. We do not support guides or tutorials on this platform. The same applies to documents, information lists, or anything similar that does not constitute an in-game usable add-on, with the exception of checklists.
No Sound Packs / Cabin Announcements
You don't own the copyrights to share sound packs or cabin announcements. Keep them on YouTube. Read more.
No empty files, unfished files, mere Read-Me files or mere images
Flightsim.to is a place to share finished mods with with the community. A mod is considered finished when other users can use it and it provides decent value or benefit for the user. It is not allowed to upload Read-Me files, files without content, or previews of upcoming mods. Everything you upload must be a working product related to Microsoft Flight Simulator.
No external downloads
Flightsim.to is a community-driven platform founded to have all mods and add-ons in one place, without requiring users to download files from (untrusted) third-party websites with the risk of not working links. We need to have full control of the content uploaded on our site, and users don't want to download a file redirecting them to an external site for another download. As a rule, all uploads linking to other websites or sources are forbidden, you must upload your file on Flightsim.to.
Screenshots are a Must!
All files must have at least one image uploaded that actually shows your add-on in-game. The image must be at least 512 x 512 px in size. We delete all files without images or images that show something that has nothing to do with your addon.
No Virus Detection
Before uploading your file, please make sure that it has 0/0 detections on VirusTotal. We will reject all files that have even one virus detection - no matter if false positive or not.
Level of Creation
All add-ons must reach a certain level of creation. You can take inspiration from others, but you must create something of your own. Plus, uploading mere "spam" items that have no use for anyone is not allowed.
Coordinates for Scenery!
If you upload scenery and you would like it to appear on our Scenery Map, please be sure to enter the coordinates in the field provided. Otherwise you run the risk that your scenery will not be included in the scenery map.
