How It Works
Local Share uses GPS-based geo-cells to create a private, temporary bulletin board for everyone within 200 meters of you.
Open Local Share
Visit local-share.tech on any device — phone, tablet, or desktop. No app download required. Your browser asks for location permission to determine your geo-cell.
Your Geo-Cell is Calculated
We use your GPS signal to calculate a private "geo-cell" — a roughly 200m × 200m grid square. Only the cell ID is sent to our server, never your exact coordinates.
Pick a Name & Post
Choose any display name (no sign-up needed) and type your message, link, or note. Hit send and your post instantly appears for everyone in the same geo-cell.
Nearby People See It
Anyone within ~200 meters who opens Local Share sees your message in real time. They can reply or post their own messages to the shared local feed.
Auto-Deletes After 1 Hour
All messages automatically expire and are permanently deleted after 1 hour. No data lingers, no history is stored. The feed stays fresh and private.
Under the Hood
Privacy by Design
Your exact GPS coordinates are never sent to our servers. We compute a geo-cell ID on your device — a grid reference that cannot be reverse-engineered to find your precise location.
Real-Time Updates
Messages appear instantly using real-time sync. You don't need to refresh the page — new posts from nearby users show up automatically as they are submitted.
Works Everywhere
Local Share is a Progressive Web App that works on any modern browser — Chrome, Safari, Firefox — on any device. No app store, no install, no updates to manage.
Frequently Asked Questions
Do I need to create an account?
No. Local Share is completely anonymous. Just choose a display name when you first post — no email, no password, no sign-up.
How accurate is the 200m range?
The range depends on your device's GPS accuracy. In open outdoor areas, geo-cells are very precise. Indoors, accuracy may vary slightly due to GPS signal strength, but the matching is always within a reasonable local range.
What happens to my messages after 1 hour?
All messages are permanently and automatically deleted from our servers after 1 hour. There is no archive, no history, and no way to retrieve expired messages.
Can strangers outside my area see my messages?
No. Only people whose device is currently located within your geo-cell can see your messages. Someone 500 meters away would be in a completely different cell and cannot see your feed.
Is Local Share free to use?
Yes, Local Share is completely free. There are no paid tiers, no subscriptions, and no hidden fees.
