Privacy policy

Effective 9 July 2026

The short version: the Onyx app collects no data about you. None. No account, no advertising, and no server of ours that anything is sent to. The one exception is this website, onyxfocus.app, which uses Google Analytics to count visitors. That is described under This website below.

What the app stores, and where

Your block list, your always-allowed list, your schedules, and your settings are stored only on your iPhone, in Onyx's own private storage. They never leave your device. If you delete Onyx, that data is deleted with it.

Screen Time

Onyx blocks apps through Apple's Screen Time system. When you pick apps to block, iOS hands Onyx anonymous references that only work on your device. Onyx cannot see which apps they are, how often you use them, or anything else about your phone. All blocking runs on-device, handled by iOS itself.

Purchases

Subscriptions and the lifetime unlock are processed entirely by Apple through your App Store account. Onyx never sees your name, email, or payment details, only an anonymous confirmation from Apple that Pro is unlocked.

Notifications

If you allow notifications, Onyx schedules them locally on your device (for example "Block finished"). They are never sent through a server.

The waitlist

If you join the launch waitlist, we store exactly what you gave us: your email address and the moment you joined, kept with our hosting provider (Cloudflare) and nowhere else. It is used for one thing, a single email when Onyx launches, and the list is deleted after that. To be removed earlier, write to the contact address below.

This website

onyxfocus.app uses Google Analytics, a service from Google, to see how many people visit and how they find us. It sets cookies in your browser and sends Google usage data such as the pages you view, how you arrived, your approximate location, and your device and browser type. It does not collect your name or contact details. Google handles that data under its own privacy policy, and you can opt out with Google's browser add-on. Our hosting provider (Cloudflare) also keeps standard technical server logs, such as IP address and requested page, to run the service, and we don't use those to identify anyone.

Changes

If any of this ever changes, this page will say so before the change takes effect, with a new effective date.
