Offline-first app studio

Apps can't leak

what they don't collect.

OfflineApps builds software that runs entirely on your device. No accounts, no cloud, no subscriptions. Your data has nowhere to go, so it cannot be lost, sold, or leaked.

Privacy by design,
not by policy.

Most apps send your life to a server and promise to guard it. We would rather not hold it at all. When the data never leaves your device, there is nothing to breach, nothing to sell, and nothing to hand over.

01

Nothing to collect

No analytics, no advertising IDs, no third-party code watching you. There is nothing to sell because we collect nothing in the first place.

02

No accounts

No sign-up, no email, no password to leak. You open the app and it just works. Your identity stays your own business.

03

Pay once, own it

No subscriptions and no upsells. Buy an app once and it is yours, with free updates. You are the customer, never the product.

04

Works offline

Everything runs on your device, even in airplane mode. Your data stays where it lives: with you, encrypted, on your phone.

Why it matters

We don't want your data.

Every time you blindly click agree to a Terms of Service. Every dodgy mile-long privacy policy. Promises to keep your information safe, far too often broken. Free apps that badger you for your money once they're downloaded. Paid apps that don't work without a subscription. We aim to do things differently.

Some apps require servers. Some apps require personal information. No app should require you to sacrifice your privacy. No app should treat your data as their product. That is our philosophy.

This keeps happening.

"The Cloud" is just someone else's computer. When their system is breached it's your data that is compromised.

Need an app that works offline?

We build privacy-first, offline-first apps for other people too. If your product should run on-device, keep working without a connection, and never hoard user data, that is exactly what we do.

  1. On-device by defaultLocal-first architecture, so the app keeps working with no signal and no backend to go down.
  2. Nothing to breachCollect only what the app truly needs and keep it on the device. You remove the biggest liability a product can carry.
  3. Own it, don't rent itOne-time purchases and software people actually own, instead of another subscription users learn to resent.
  4. Built to lastSimple, dependency-light builds that keep running for years without a server bill or a rewrite.
