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
Every uploaded file must include a description in English. Files lacking an English description will be deactivated.
Converted Aircraft or Scenery
When uploading aircraft to our platform, it is important to remember that you must have the model owner's permission. This applies to both freeware and paid models. It is crucial to respect copyright laws and the intellectual property of others. Even if the original creator has shared their model for free, it does not automatically give you the right to redistribute it. You must be able to provide proof that you have obtained legal permission to use assets from another developer.
Donationware
All files must be completely free. Offering updates or exclusive features for a fee is not allowed. You may ask for donations, but you may not offer anything in return.
While Flightsim.to primarily hosts freeware content, paid content is allowed in the Flightsim.to Store. To sell content, you will need to apply for an official vendor account. Read more about this here.
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.
Respect Intellectual Property
Do not upload converted aircraft without the model owner's permission, even if it used to be freeware. 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.
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.
Best Practices for File Naming
Choose filenames that clearly indicate the content and purpose of the addon. Avoid generic or ambiguous names that do not provide any information to users. Instead of "OPEN ME FIRST.zip" consider naming the file something like "Boeing 747-400 Passenger Variant" to allow users to identify what is inside the archives. Maintain a consistent naming format across all your addons to make it easier for users to identify and manage them.
Do not upload multiple parts
Respect the file size limitation on Flightsim.to which is 3.0 GB per add-on. Uploading multiple parts or splitting files, such as Part 1, Part 2, and so on, is prohibited. Each add-on must function independently without requiring any additional downloads.
Guidelines for Add-On Titles
When uploading airport scenery, it's necessary to include the ICAO code, if available, at the beginning of the title for your upload. They are not allowed inbetween or at the end, the title of your file must start with the ICAO. Our guidelines for naming titles also require avoiding unnecessary capitalization, symbols, or words, so-called spam capslock or clickbaits. Please include only the essential elements in your title.
