weathr holds an account, the moods you cast, the groups you are in and, if you switch it on, where you are now. It has no ads, no trackers in the app, and nothing to sell. Places show moods and never people: at a postcode, an address or a venue, every signal is shown without a name, on any setting.

What weathr stores

weathr does not store a location history, a contact list, your address book, your photos, or anything about what you do outside weathr.

Who can see it

Your mood is shown to the groups you are in, as part of their weather. A group's sky is a proportion of its members' moods, not a list.

Blind hides who, never the mood. Casting blind shows your symbol without your name. Be realistic about what that is worth: in a group of two or three, hiding the name hides very little.

In a channel, members can see the member list, and a person who casts publicly is shown with their mood and their words. A person who casts blind is not.

In a place, nobody is named at a postcode, an address or a venue, at any headcount and on any setting. That is not a preference you have to find; it is how those readings are built.

A link to a group unfurls as a picture showing the group's name, its headcount and its weather. It never names a person, including whoever cast last.

Location

Reporting your location is a switch that is off until you turn it on, on each device separately. With it off, weathr never asks your device where it is.

With it on, two things are worth knowing. The coordinates are turned into place names on your device, by a geocoder (Geoapify), and what reaches weathr's servers is the answer, that is the street, postcode, city, region and country, rather than a precise point. And weathr stores where you are, not where you have been: one row, overwritten when you arrive somewhere else. Turning the switch off stops new reports; it does not move you.

Standing somewhere puts your mood into that place's weather and every larger place around it, and there is no opting out of that while you are there. What protects you is that the fine rungs never name anybody. The full technical account is in our documentation, and the short version is: where you are never gives away who you are.

PlausibleCounts visits to the public demo onlyPage views, with no cookies and no cross-site tracking

weathr does not sell data, does not share it for advertising, and carries no advertising or third-party tracking in the app.

Cookies and what is kept on your device

weathr sets one cookie, weathr_session, which records only that somebody is signed in on this browser, so that weathr.ai shows the app rather than this website. Your sign-in token and your preferences, such as the theme and the location switch, are kept in your browser or on your phone and are not sent anywhere. The demo site counts visits with Plausible, which uses no cookies.

The demo is a separate world

The live demo is populated by invented people, and visitors borrow one of those accounts. It runs on its own database. Real accounts and invented ones never share a group, a sky or a server.

Your choices

Children

weathr is not intended for children under 13, and weathr does not knowingly collect information from them. There is no age verification in the app today, and no parental controls. If you believe a child under 13 has an account, write to us and we will remove it.

Changes

If this page changes materially, the date at the top changes with it. Questions go to privacy@weathr.ai.

See it rather than read about it

The demo needs no account and no download: a live map of invented people whose weather moves while you watch. Everything on this page is true of it.
