Apps
Small apps that do one thing and keep your data on your phone. Each one works with no signal, and each one tells you exactly what leaves the device — usually nothing.

The same three promises
- No analytics, no advertising, no tracking. Not in any of them, ever. Nothing you do in these apps is measured, sold or shared, and there is no advertising identifier anywhere.
- They work with no signal. Everything each app needs to do its job ships inside it, so it behaves the same in a basement, on a plane, or in a waiting room. The one exception is FirstHey AI, whose characters need the network to answer.
- Each app says what leaves the phone. For most of them the answer is nothing at all. Where something does leave — the first name Nightleaf sends to write a story, the fact that a subscription exists — it is written plainly on that app’s own page rather than buried here.
Pricing differs: some are a single purchase, some a subscription. Each app’s page says which, and the App Store asks you before anything is charged.
The privacy policy and the terms of use cover every app on this page. FirstHey AI also has its own privacy policy and terms, because it is the one that sends conversations to an AI service.
Support
Every app has its own page above with its common questions. Anything not answered there goes to oguzhancart1@gmail.com.
