Fiskos

Fiskos

A private, offline-first space for your people.

Chat, call, share photos & files, make plans, split expenses — and even play games together — even with zero internet or signal. No account. No servers. End-to-end encrypted.

No Wi-Fi? No signal? It still works.

Underground gym, a plane, a campsite, a power cut, a country with no roaming — Fiskos connects your phones directly over your local network, a hotspot, or even phone-to-phone with Wi-Fi Direct (no router at all). You stay together when everything else needs the internet and doesn't have it.

Everything in one private space

A calm home for the people closest to you — not a noisy feed, no strangers, no ads.

💬

Chat & calls

1:1 and group chats with reactions, replies and voice messages — plus voice & video calls. No phone number needed.

📷

Share anything

Photos, videos, files and voice notes fly between phones over the local network — fast, and never uploaded to anyone's cloud.

🗓️

Plan together

A shared calendar with RSVPs, reminders and an “Upcoming” agenda, plus shared notes and checklists for trips and to-dos.

🧾

Split expenses

Track who paid and split fairly — even just some people — in any currency. Perfect for trips and roommates.

📍

Find each other

Share live location and a “find each other” radar with the people you choose — sent only to them.

🎲

Play together

Backgammon (Tavla), Chess and Ludo — play head-to-head on your two phones, fully offline.

Private by design — not by promise

Most apps ask you to trust their servers. Fiskos doesn't have any. Privacy isn't a setting here; it's how it's built.

No servers, no account. No phone number, no sign-up, no tracking. Your data lives only on your devices.
End-to-end encrypted. Only you and the people you pair with can read your messages — no one in the middle, not even us.
Encrypted on your phone. Everything is encrypted at rest with a key kept in your phone's secure hardware.
App lock. Require a fingerprint, face or PIN to open Fiskos.
Disappearing messages. Set any chat to auto-delete after an hour, a day or a week.
Panic wipe & verified contacts. Erase everything instantly if you need to, and verify a contact's safety number so no one can impersonate them.

How the no-internet part works

1

Pair once. Scan a QR code and confirm a safety emoji — even fully off-grid over Wi-Fi Direct. Done, you're connected.

2

Connect directly. On the same Wi-Fi, a hotspot, or phone-to-phone, your phones find each other and talk peer-to-peer — no server in the middle.

3

Stay in sync. Messages and shared plans merge automatically when you reconnect, so nothing is lost while you're offline.

Made for being together

Anywhere a few people are in one place and the signal isn't.

Never lose your space

Moving phones or worried about losing everything? You're covered — without a cloud.

🔄

Move to a new phone

Send your whole Fiskos — identity, chats, files and pairings — straight to your new phone over the same encrypted link your chats use.

🛡️

Encrypted backup

Save an encrypted backup file, protected by a 12-word recovery phrase. It never touches the cloud — restore it on a lost or broken phone.

🤝

Bring your people

Fiskos needs someone nearby, so it's easy to invite a friend with a link or QR — set everyone up before you head somewhere with no signal.

Free to use — with an optional Fiskos Pro

Everything above is free. A one-time Fiskos Pro unlocks large-file & full-length video sharing and a supporter badge — and because it sponsors your circle, one of you buys it and everyone you pair with gets it too. No subscription, no ads, ever. It just keeps an indie, privacy-first app independent.
