Places are stored in this browser. Map tiles cache here as you pan. Nothing is uploaded to a Placechat server — the site only serves this page.
Each relay is a live WebSocket on this device. 4–8 is enough. More copies the same chat, uses battery and data, and shows your IP to more operators — it does not make a bigger room.
Default for every chat on this device. Off by default. Hiding weaker notes only changes what you see here — other people keep their own filter. 12 bits is enough on a phone; higher values mainly slow this device, not a spammer with a PC. A noisy room can use its own values from inside that chat.
This filter only applies in this browser.
Also ignores private-chat requests whose wrap has less work — before decrypting.
Hide map places and chat messages unless they have a + or − vote of at least this many bits. Off means PoW is not checked.
This filter only applies in this browser.
Gold if the last message is within this many days. People in a chat still show in green even when nobody is writing. Off = only people present.
On = only places that have at least one photo. Off = every place as usual.
This name is shown in chat, votes, reviews, and everywhere you appear on Placechat.
Save the nsec file now. Anyone with that key can post as you. It lives only in this browser — private windows lose it, and this site never stores it on a Placechat server.
Placechat is a static client: HTML, CSS, and JavaScript files. Whoever publishes those files is not operating a chat service, a social network, a hosting platform, or a user database. This origin does not receive, store, index, or moderate your messages. There is no Placechat server for chat.
Chat, votes, reviews, and presence leave your device only toward public infrastructure that you choose or that the client calls on your behalf: Nostr relays, OpenStreetMap / OpenFreeMap / Overpass, and similar third parties. Those operators are independent. The person who put this page online does not run them, does not control what they keep or delete, does not see your messages, and is not a publisher or editor of user content.
Your browser signs events with a key stored on this device and publishes them to relays you select. Map tiles and named places come from OSM-related services. Relays and map operators have their own terms, logs, and retention. Copies can remain on relays, other devices, archives, and search indexes. A delete or edit in this client is only a request; nobody here can guarantee removal from the internet.
You alone are responsible for everything done with your key: messages, votes, reviews, nicknames, links, and presence. You choose the relays. You are the author and publisher of that content toward those third parties — not Placechat and not the operator of this origin. Other people may copy or re-share what you post. If you lose the key, that is your loss. You agree to use this client lawfully and to hold the operator harmless for claims arising from your use or your content.
You may not use this client to commit crimes, harass people, spread malware, spam relays, or share or link to illegal content — including any sexual content involving minors. Abuse is forbidden. If you do it, it is solely your act. The operator of this origin does not publish, adopt, or endorse user content.
Links in chat are written by users and open other websites. Placechat and the operator do not control those destinations. You will be asked to confirm before a link opens. Follow links at your own risk.
This origin only serves the page files. Your browser may also call map and geolocation services (OpenFreeMap, OpenStreetMap / Overpass / Postpass, geojs, BigDataCloud) and the Nostr relays you select. Those are independent operators. They may see your IP. Language suggestion from GPS/IP is requested only when you open Language — not on every visit. Relays are WebSockets from this device; the page Content-Security-Policy allows WebSocket connections so you can add your own relay.
This client is provided “as is”, with no warranty of any kind: availability, fitness, security, privacy from relays or map services, or that a room is empty of abuse. The operator has no duty to monitor, take down, or preserve content. To the maximum extent allowed by law, the operator is not liable for user content, third-party services, lost keys, lost data, or any damages from using this page. Using Placechat means you accept these terms. If a court disallows a part, the rest still applies. If a translation differs, the English text is the reference.
For this page, not for chat or relays:
Suggested from your network and GPS when you have not picked one. Chat messages stay as people wrote them.
Proof of work for this chat only. Both sliders off = follow the Relays default. Move either slider to override this room. Mining when sending costs time on this device; 12 bits is enough on a phone. Hiding weaker messages only changes what you see — other people keep their own filter.
You created this place
These people can write without PoW
Alerts only while Placechat is open in this browser. Off by default.
PoW for this photo
Only this photo. Off = no mining, then it is uploaded.
0/280
PoW for this vote
Only this + or −. Not the PoW used when sending a chat message.
Name it (more than 5 letters). Creating it mines Proof of Work so it can show on other maps.
Name needs more than 5 letters.
