Privacy Policy — Hollow

Last updated: 23 October 2026

Hollow reads satirical meditations aloud with your phone's voice, and collects nothing of yours to do it.

Data controller: MindContact di Luttino Roberto, Via Ivrea 41, 10016 Montalto Dora (TO), P.IVA 10699860010, reachable through the contact form on mindcontact.app.

In short

Hollow creates no account, asks for no sign-up, and collects no name, email or contacts.
We run no servers: no app data is ever sent to us.
The only data leaving your device is what Google AdMob collects to serve ads, and the session texts if the phone's speech engine synthesises them online.

Permissions and what they are for

Permission	Why	What leaves the device
Internet	ads; speech synthesis, only if the engine works online	see “Advertising” and “The voice”

The voice

Hollow reads its sessions with the text-to-speech engine installed on the phone (usually “Speech Services by Google”). The app only hands it the session texts, which we wrote and which are the same for everyone: nothing about you. Depending on the engine and the voice chosen in the phone's settings, the speech may be synthesised on the device or on the engine provider's servers, under its own policy (for Google: policies.google.com/privacy). We declare it because we cause the reading, even though we do not perform it.

Advertising

Hollow shows ads through Google AdMob. AdMob may collect and process:

the device advertising identifier (Advertising ID / IDFA);
the IP address and technical device information;
ad interaction data.

Google processes this data as an independent controller. Policy and options: policies.google.com/technologies/ads

You can limit personalised ads from your system settings:

Android — Settings › Privacy › Ads
iOS — Settings › Privacy & Security › Tracking

In the EEA, the UK and Switzerland, Google's consent message appears on first launch; until you answer it, the app requests no ads at all.

Data that stays on the device

App preferences (favourites, streak, voice pace, sound) are stored on the device only and are removed when you uninstall the app.

Children

The app is not directed at children under 13 and does not knowingly collect their data.

Your rights

With no account and no backend, we hold no data about you and cannot identify you. For data processed by Google AdMob, exercise your rights directly with Google, using the contacts in its own policy.

Any question: write to us through the contact form on mindcontact.app.

Changes

Any change to this policy updates the date at the top. Previous versions remain in the history of the public repository mcma-docs.
