Privacy

The freedom to map the world in OpenStreetMap has limitations where it violates the privacy of people living in this world.

As an international project, we should respect personal information as well as the consensus in the community about them.

OpenStreetMap has no method to record individual agreements to publish particular personal data. Such data would not be verifiable anyway, so even with an individual agreement to publish it would not fit OpenStreetMap.

Therefore, some rules are:

  • Do not map where individual people live, in particular do not add the names of inhabitants to dwellings.
  • OpenStreetMap is not a property registry, thus do not map individual ownership of buildings or plots. (see also: Parcel.)
  • OpenStreetMap is not a phone book. Do not map contact data of individuals. For mapped businesses and offices that are on public record, adding contact information is accepted.
  • Do not name individuals in OpenStreetMap tags, unless their name is on a business sign posted towards the street, or part of the business name and available in public records.
  • Do not map the personal behaviour, preferences and habits of individuals.
  • Limit the detail of mapping private backyards. As a guideline, permanently installed private swimming pools, or some structure of a semi-public garden appear to be acceptable, but on the borderline between "acceptable" and "not acceptable". Add access=private as appropriate.
  • Do not map the personal possession of private objects or their location (like vehicles, TV-sets, washing machines, or how many livestock belong to a household); tags for such should be limited to communal use, e.g. a laundry facility on a camp site.
  • Do not map personal private indoor facilities, like showers and toilets in private apartments/houses.
  • Mapping private buildings, private roads (including driveways), private parking is considered as completely acceptable. Add access=private as appropriate to roads, parkings etc.

Who has a Right to Privacy?

Only living human beings are considered to have a right to privacy. The deceased do not generally enjoy these rights, although the privacy of their living relatives might be relevant[1]. Also, organisations (corporations, clubs, businesses) do not enjoy a right to privacy.

Other Reasons not to Map

Beyond the privacy of individuals, there may be other reasons not to map certain things outside of the scope of this page. While a rough consensus exists on these, there are no written rules:

  • Protection of endangered species. This would apply to e.g. mapping an eagle's nest or rare plants
    • mapping rare plants in a botanical garden would be fine
    • it is also considered fine to map existing road/paths, if using them is forbidden use access=no/access=private rather than deleting them
  • Safety concerns. This would apply to e.g. mapping the location of safe houses for victims of domestic violence or places of worship of religion persecuted in a given region.
  • Indigenous sacred sites where the traditional owners and their representatives have asked that the locations of sites be kept private to protect them and maintain their sanctity.

Limitations

Note that this page is not listing of all things not mappable for privacy reasons. If something is not clearly covered by rules above there still may be a clear consensus whatever it is OK to map it - possibly due to privacy concerns.

Note also that this page is an attempt to document consensus, it is not some binding official decision.
