Terms of use
Short, because the forest is the point. Using Vider means you agree with these.
Last updated 6 October 2026.
Never munch on a hunch
Vider helps you learn mushrooms. It does not identify them for you, and nothing in it is advice to eat anything. Only eat what you know for sure, and when in doubt, leave it out. You alone are responsible for what you pick and eat.
The way back is a help, not a guarantee
Vider records your walk and leads you back as well as the GPS, the map data and the battery allow. All of these can be wrong or run out. Keep your bearings, tell someone where you are going, and do not rely on any phone alone in the forest.
The map and the mushroom ground
Where mushrooms are "likely" is a reading of public terrain data, not a promise of mushrooms. Respect the right of public access (allemansrätten), private land, nature reserves and the people who live there.
Your account
An account is optional. Keep your sign-in to yourself, and delete the account in the app if you no longer want it. Vider may close an account that is used to harm the service or others.
Liability
Vider is provided as it is. To the extent the law allows, Vider and its maker are not liable for any loss or harm that follows from using it, including from mushrooms picked, routes taken or data lost.
Changes and law
These terms may change; the date above says when. Swedish law applies.
