Radar

Privacy Policy

Last updated October 14, 2026

This policy explains what Radar knows about you, why, and what you can do about it. Radar is built on a simple idea: posts are public, accounts are small. Radar is operated by Carlos Lagrange, in the United Kingdom, who is responsible for the data described here.

1. What we collect

Your account: your email address (to sign you in; it is never shown to anyone), and the name, handle, bio and picture you choose, which are public. If you sign in with Apple or Google instead of an email code, they give us your email address (Apple lets you hide it behind a relay address) and your name, and Google gives us your profile picture, which we copy as your first picture. We never receive your Apple or Google password.

What you post: the words, photos and videos of your posts and replies, and the location you pin each post to. All of this is public. Photos are re-encoded before upload, which removes the location and camera details stored inside the file.

What you do: your likes, saves, follows, blocks, reports, responses to posts, and your private conversations with other people. Feedback is a separate conversation with Radar’s AI assistant: its messages, the screenshots you attach and the feedback extracted from them are accessible to you and authorized Radar maintainers.

Feedback diagnostics: when you write to Feedback, we include available app version, build, operating system, device model or browser, screen size and language, and where you were in Radar when you wrote: the screens that led to Feedback and the area of the map you were looking at (to about a kilometre). This helps investigate your report. We do not attach messages from other conversations.

Your location: only while you use the app and only if you allow it, to show where you are on the map, to open Radar on what is around you and to start a new post there. We do not track your location in the background and we do not keep a history of where you have been. What we store is the location of each post you make, and your home if you set one.

Your home: if you set a home, we store the point you chose and use the area around it (2.5 km) to open Radar there and to gather what is happening nearby. It is private: shown only to you. When we look for events around your home, that search uses only a coarse position (the middle of a square about 150 metres across) and a coded reference to your account; its record is kept for 90 days and erased with your account. The sites we search are given only that coarse position.

Technical data: basic logs our servers keep for a limited time (such as IP address and device type), to keep the service secure and working. If you turn on notifications, a token that lets us send them to your device. When Radar opens without knowing where you are, your device asks a lookup service (GeoJS) which city your internet connection is in, so the map can open there; GeoJS sees your IP address to answer, and the answer is used on your device and not stored on our servers.

How you use Radar: the screens you open, what you tap, what you search for and what you do with posts (opening, answering, saving, sharing), with the area of the map you are looking at (to about a kilometre), your approximate location from your connection, and your device and app version. It is tied to your account and helps us understand what works and what does not. A tap inside a private conversation is not described. On the web, a visit may be recorded so we can replay how the app looked and behaved; what you type is hidden, and the words and photos of private conversations are masked.

App diagnostics: when something fails or is slow, a report helps us find out why. It includes the error, what the app was doing just before it, a picture of the screen at that moment, operation timings, your account’s identifier and handle, your IP address, and app version and device information.

What Radar gathers from public pages: Radar also shows events and local news that it gathers from public pages: event listings, the press, and the public accounts of venues and public bodies. Each is shown with its source and a short summary written by an AI model. If one of them is about you or something you run and you want it corrected or removed, write to the address below.

Radar’s website: if you ask for an invite, or tell us about an event, on radar.place, we keep the email address you give, the language you asked in, the country your connection is in and when you asked, and, for an event, what you tell us about it (its name, when and where it is, and about how many people come). We use it only to write to you about your invite or your event, and keep it until you ask us to delete it. The website sets no cookies and uses no analytics.

2. Why we use it

To run Radar: to show posts on the map and in the feed, deliver messages and notifications, open Radar on your area and gather what is happening there, suggest places and people, and keep the service safe (fighting spam and abuse, handling reports). To understand what a post is about, its text is processed by an AI model (section 3). When you choose to write to Feedback, an AI model replies and organizes your feedback for the team. We do not sell your personal information, and we do not use it for advertising.

3. Who we share it with

Everyone: anything public, as described above, including people who are not signed in.

Service providers who process data for us, under contract, only to provide their service: Supabase (database, sign-in, file storage), Mapbox (maps and place search; it receives the area of the map you are looking at and what you type when you search for a place), Cloudflare (it re-encodes and streams the videos you post, and hosts Radar’s website and what is asked through it), Anthropic (post text for classification, and Feedback conversation text, screenshots and diagnostics to reply and organize reports; we do not attach your account email or conversations with other people), Expo (delivering notifications and app updates), Sentry (app error reports and operation timings, as described in section 1), PostHog (how the app is used, as described in section 1), and the email provider that sends your sign-in code.

Apple or Google, if you sign in with them: they learn that you use Radar. GeoJS, a public lookup service, sees your IP address when your device asks it which city your connection is in. The sites we search for events are given only a coarse position near your home, as described in section 1, and nothing about you.

Authorities, when the law requires it, or to protect someone from serious harm.

4. How long we keep it

Until you delete it. Deleting a post removes it from Radar. You can delete your account in Settings, under Account: it is final and takes effect at once. It removes your profile and picture, your posts and replies with their photos and videos (and the replies other people wrote under them), your likes, saves, responses, stamps, follows and blocks, your home, your notification tokens, your Feedback conversation and its reports, and the photos you sent in conversations.

Messages you sent stay in the other person’s inbox, shown as from a deleted account, without your name, picture or profile. Reports you filed, and reports about you or your posts, are kept without your identity for 90 days, so that deleting an account does not erase what was reported. Backups and security logs are kept for a limited time after that.

The records of use and the diagnostic reports held by our analytics and error-reporting providers (section 3) are not erased automatically when you delete your account: write to the address below and we will erase yours.

5. Your choices and rights

You can edit your profile, delete your posts, block people, change your home, delete your account (Settings, Account), and turn location and notifications off in your device settings at any time. Depending on where you live you may have the right to see, correct, export or delete your data, and to object to some uses of it. To use any of these rights, write to the address below. You can also complain to your local data protection authority; in the United Kingdom that is the Information Commissioner’s Office (ico.org.uk).

6. Children

Radar is not for children under 13 (or the minimum age where you live). If we learn that a child has made an account, we will delete it.

7. Where your data is

Radar's servers are in the United States. If you use Radar from elsewhere, your data is transferred there and processed under this policy.

8. Changes

If we change this policy in a way that matters, we will tell you in the app before the change takes effect.
