Volume Limiter (package com.revaltronics.volumelimiter)
Developer: Revaltronics · Last updated: 4 September 2026
This Privacy Policy explains how the Volume Limiter mobile and TV
application (the “App”) handles information. The App needs no account, no sign-in
and no personal details to work, and everything you configure stays on your device. It does,
however, use three Google services — advertising, analytics and payments — and this
policy sets out exactly what each of them involves.
1. Information stored on your device
The following is stored locally on your device only and is never uploaded to
the developer or to any server we operate:
Your maximum volume limit, and whether the limiter is switched on.
Your PIN, if you set one. It is stored as a salted, one-way hash —
the PIN itself is never saved in readable form and cannot be recovered by us.
Your lock preferences (whether a PIN is required to open the App or to change the limit),
and whether the keypad is scrambled.
Volume profiles and schedule rules you create.
A local history of volume changes, kept on the device for 30 days and then
deleted automatically.
If you use the phone remote: whether it is enabled, the local network address the TV is
listening on, and the names of phones you have paired.
All of it is removed when you clear the App’s data or uninstall the App.
2. The phone remote (local network only)
On Android TV, the App can let a paired phone on the same Wi-Fi network change
the volume limit. When you switch this on, the TV advertises itself on your local network and
listens for connections from your phone.
This traffic goes directly between your own devices. It does not pass
through the developer, and there is no cloud service involved.
Pairing requires your PIN. A phone that cannot prove it knows the PIN is refused.
The feature is off by default and requires a PIN to be set before it can be enabled.
3. Analytics (Google Analytics for Firebase)
The App uses Google Analytics for Firebase to understand how the App is used in
aggregate — for example how many people use a feature, and how many have purchased the
paid unlock. This helps us decide what to build and fix.
You can switch this off at any time in
Settings → Privacy → Share anonymous usage data. It is on by default; turning
it off stops collection and upload straight away, and the App keeps working exactly as before.
What is collected
Why
A randomly generated app instance identifier
To count distinct installs without identifying you
Device and app information: device model, operating system version, app version, language, country or region
To understand which devices to support and to diagnose problems
Usage events, such as screens opened and in-app promotions shown or dismissed
To see which features are used
Whether this install owns the paid unlock (a true/false flag)
To compare the experience of free and paid users
We do not collect your name, email address, phone number, contacts, precise
location, photos, files, or the contents of anything on your device. We never sell or rent any
information, and we do not attempt to identify individual users.
The App offers a single one-time purchase that unlocks the paid features. The
transaction is handled entirely by Google Play.
The developer never sees or stores your payment card, billing address, or Google account
details. We only receive confirmation from Google Play that the purchase is owned.
Our Google Play developer account is linked to our Firebase project, which means Google
reports aggregate purchase and revenue figures to our analytics. These are
totals, not records of who bought what.
Refunds, payment history and receipts are managed by Google Play, not by us. See
Google Play refund help.
5. Advertising (Google AdMob)
Users who have not purchased the paid unlock see advertisements provided by
Google AdMob. Buying the unlock removes them. To serve ads, Google and its
partners may collect and process information such as a device advertising identifier,
approximate (non-precise) location derived from your IP address, and general device
information, in order to deliver and measure ads.
You can opt out of personalised advertising, and reset or delete your advertising ID, in
your device settings under Settings → Google → Ads (or
Privacy → Ads).
6. Your choices and rights
Turn analytics off: open
Settings → Privacy → Share anonymous usage data in the App and switch it
off. This takes effect immediately, stops collection and upload, and is remembered on that
device. Advertising is unaffected — see the two entries below.
Stop all collection: uninstalling the App ends analytics and advertising
collection, and deletes everything stored on the device.
Reset your advertising identity: use the device settings linked in
section 5 to reset or delete your advertising ID, and to turn off ad personalisation.
Remove ads entirely: purchase the paid unlock.
Access, correction and deletion: depending on where you live (for example
under the GDPR in the EEA and UK, or the CCPA in California) you may have the right to access,
correct, delete, or restrict processing of personal data, and to object to it. Because we
hold no account and no directly identifying data, the most reliable way to exercise these
rights is to uninstall the App and reset your advertising ID. You can also contact us using
the details in section 9 and we will respond as required by law.
We do not sell or share personal information for cross-context behavioural
advertising as those terms are defined under US state privacy laws.
7. Permissions the App uses
Internet and network state — to load advertisements, to send
analytics, to verify your purchase with Google Play, and to run the phone remote on your
local network.
Foreground service — keeps the volume limiter running so your chosen
limit stays enforced.
Run at startup — re-enables the limiter after the device restarts,
if you turned it on.
Notifications — shows an ongoing notification while the limiter is
active, as Android requires for this kind of background work.
The App does not request access to contacts, photos, microphone, camera, precise location, or
your files.
8. Data security, retention and children
Your settings and PIN never leave your device, so you remain in control of them, and the PIN is
protected with salted hashing. Please note that the App is a deterrent designed to discourage
casual changes — for example by children — and is not a guarantee against a
determined person with full access to the device.
On-device volume history is deleted automatically after 30 days. Analytics and advertising data
are retained by Google according to their own published retention settings and policies.
The App is intended for adults, typically parents or carers setting a limit for someone else. It
is not directed to children and we do not knowingly collect personal information from children.
If you believe a child has provided information through the advertising or analytics services,
please contact us and refer to the Google privacy resources linked above.
9. Changes and contact
We may update this Privacy Policy from time to time. Updates are posted on this page with a
revised “Last updated” date. Continued use of the App after changes take effect
constitutes acceptance of the updated policy.
Before publishing: confirm the developer name, contact email and effective date
above, host this file at a public URL, and add that link in the Play Console listing. Then update
the Play Console Data safety form to match this policy — it must now
declare app activity and device identifiers collected for analytics and advertising, which the
previous version of this policy did not cover.
