Privacy Policy

Regula · Last updated 21 August 2026

The short version. Regula has no accounts and no logins. We never ask for your name, email address or phone number, and we cannot identify you. Your learning progress is stored on your own device and, if you are signed in to iCloud, in your own private iCloud account — which we have no access to.

Who we are

Regula ("the app", "we", "us") is a grammar practice app for iOS. If you have a question about this policy, email mach200studio@gmail.com.

What we collect

DataWhyWhere it goes
Anonymous usage events (app opened, quiz started/completed, paywall viewed) To understand which parts of the app are used, so we can improve them TelemetryDeck, hosted in the EU
Device and app information (device model, OS version, app version, language, country) To show the right paywall and measure whether it works Superwall
Subscription purchases To unlock Premium features Apple. We never receive your payment details
Question reports you choose to send (question ID, reason, your optional comment, timestamp) To fix mistakes in quiz questions A private Google Form we own
Your progress, settings and quiz history To run the app and keep your streak Your device, and your own private iCloud account if you are signed in

What we do not collect

Analytics

We use TelemetryDeck to count anonymous, session-level events — for example that a quiz was completed, not which questions you answered. TelemetryDeck does not use advertising identifiers and stores its data in the European Union.

Per-question data stays on your device. It is what powers the statistics screen inside the app, and it is never sent to us.

Paywalls

We use Superwall to deliver and measure the Premium upgrade screen. Superwall receives device and app information so it can decide which version of the screen to show and record whether it led to a purchase.

iCloud sync

If you are signed in to iCloud, your progress, settings and quiz history sync through Apple's CloudKit to your own private iCloud database. This is your storage, not ours: we cannot read it, and it is covered by Apple's Privacy Policy. If you are signed out, everything stays on the device and the app works normally.

Purchases

Premium subscriptions are sold and processed by Apple through the App Store. We receive confirmation that a subscription is active — never your card details or billing address.

Children

Regula is not directed at children under 13, and we do not knowingly collect data from them. Since we collect no personal data at all, no such data can be stored.

Your rights

Because we hold no personal data about you, there is nothing for us to look up, export or delete on request. You remain in control of everything the app stores:

Changes

If this policy changes, the date at the top of this page changes with it. Material changes will be announced in the app.
