Three ways to stay connected.

LAN direct

Connect directly nearby

YouLocal networkThem

Send over a reachable local network, without internet or an Exchange. Both devices must be reachable at the same time.

Local Exchange

Stay connected through a local hub

YouLocal ExchangeThem

A local Renxil Exchange can hold encrypted messages until recipients reconnect—even without internet. Requires a configured, authorized mailbox.

Global Exchange

Reach across networks

YouGlobal ExchangeThem

A global Renxil Exchange carries encrypted messages over the internet and can hold them while recipients are offline. Requires an available, authorized Exchange route.

End-to-end encrypted, whichever path you use.
Direct delivery when available. Exchange storage when needed. Messages remain queued when no eligible route is reachable.

Stored or delivered—what’s the difference?

Stored on Exchange means awaiting delivery—not yet received. Recipients must reconnect to that Exchange before messages expire. Leaving a local network may prevent access to its local Exchange; messages are not automatically copied to a global Exchange.

Shared places. One map.

Share locations in chat and see them together on the conversation’s shared map. Shared area polygons appear there too.

  • View shared points and area boundaries on the private chat map.
  • Keep shared map events together within their conversation.
In practice

Coordinate a search: share an area and a meeting point, then view both on the chat map.

Sharing needs a reachable transport; saving a marker does not broadcast it to everyone.

Draw the boundary.

Draw polygons to mark an area on the map. Keep boundaries, saved places and distance tools together.

  • Name an area and save its boundary.
  • Drag vertices to reshape it; add or remove nodes.
In practice

At camp: outline the campsite or a search area, then mark the meeting point.

Pair nearby. Start talking.

Discover nearby devices and compare verification codes. Start end-to-end encrypted chat without creating a cloud account.

In practice

Meet before a trip, verify each other, then stay in touch over a reachable local network.

Keep your own trail.

Choose to record your trail locally. Share only a selected time range, with the level of detail you choose.

In practice

After a walk, share the afternoon’s route without sharing the rest of your day.

More than a text message.

Send text, a quick sketch, a photo, a file or a location. End-to-end encrypted chat can use a reachable local network without a cloud account.

  • Pair nearby phones and compare the verification code.
  • See delivery and direct-reachability status.
In practice

Without internet: use the same reachable LAN, send a sketch, and keep the conversation together.

No internet does not mean unlimited range. Radio links need compatible hardware; delivery depends on the available route.

Read the terrain.

Map layers, range rings and offline packages for everyday navigation and field use.

  • Switch basemaps or add your own tile URL.
  • Check distances with range rings and measurement tools.
In practice

Before heading out: save your map package and check the area around camp.

Send the meeting point.

Share a dropped pin, a saved marker or your current location from chat.

  • Send coordinates with the conversation for context.
  • Open a shared location on the map.
In practice

On a walk: send the meeting point, then add “Meet at the east entrance.”

Sharing needs a reachable transport. A shared point is not continuous live tracking.

Keep useful knowledge close.

A local library for imported documents, notes and task lists. Organize your reference material alongside the conversations that use it.

  • Organize folders; filter files, notes and tasks.
  • Search names and note content; browse chat attachments.
In practice

Before a trip: keep equipment instructions, a meeting-point note and a packing checklist on your phone.

Import your reference files before heading offline.

You own your data.

Keep it local. Choose what to share. Take a copy with you.

Take your data with you.

Export selected data to an encrypted Renxil archive and import it locally. Keep a copy where you choose, without mandatory cloud storage.

In practice

Before changing phones, save an encrypted local archive and keep its password safe.

Protect what stays on your phone.

Protect local data with an encrypted vault, an app password and optional biometric unlocking. End-to-end encryption protects private chat between devices.

In practice

Set an app password, then enable biometric unlocking on a supported device.
