Aurelius Privacy Policy

Introduction

Aurelius ("the app") is developed by Grisu Studio. Your reading habits and personal reflections are private: what quotes resonate with you, which ones you save, and when you read them stays on your device. We run no servers and hold no copy of your data. The only data that leaves your phone is what Google's advertising SDK sends in order to serve the ads that keep the app free — and you control whether those ads are personalised.

Scope

This privacy policy applies solely to the Aurelius mobile application.

Data We Collect

Stored on your device only, never transmitted to us: your saved quotes and collections, language and theme preferences, notification time, and the answer to the one-time age question as a bracket only — either "under 13" or "13 or over". If you pick a birth year it is converted to that bracket and immediately discarded; the app never stores a date of birth. We use no analytics and no crash reporting, and we never know which quotes you read or save. Collected by Google AdMob, not by us, in order to serve ads: your device advertising identifier (IDFA on iOS, Advertising ID on Android), IP address, coarse device information such as model and OS version, and ad interaction data.

How We Use Your Data

Your saved quotes, collections and settings are used only inside the app and never leave your phone; searching happens entirely on device, and the quote library ships with the app so reading works offline. Advertising data is used by Google to deliver and measure ads. In the European Economic Area and the United Kingdom the app shows Google's consent form before any ad loads, and on iOS it shows Apple's App Tracking Transparency prompt. Declining either one keeps ads non-personalised rather than removing them, and you can revisit both choices at any time from Settings → Privacy and ads. The app also caps the content rating of every ad it requests.

Children's Privacy

Aurelius is listed for ages 13 and over and is not directed to children. The app asks one neutral, skippable age question and keeps the answer as a bracket rather than a date of birth. If you indicate you are under 13, the app switches to child-directed ad treatment on that device: ads restricted to the "General audiences" rating, never personalised, no advertising identifier used, and Apple's tracking prompt never shown. The setting can be changed at any time in Settings → Privacy and ads.

Data Security

Because we run no servers, there is no copy of your data anywhere for us to lose or be compelled to hand over. Your collections and preferences live in the app's private storage on your device, protected by the operating system's sandboxing and your device encryption. "Delete all my data" in Settings erases everything the app has saved, and uninstalling removes it too. Data handled by Google AdMob is governed by Google's own privacy policy at policies.google.com/privacy.

Changes to This Privacy Policy

We will update this policy whenever the app's behaviour changes in a way that affects it — as we did on August 30, 2026, when advertising support was documented — and the "Last Updated" date will change with it. Continuing to use the app after an update means you accept the revised policy.
