Timezone converts a moment between time zones, shows the zones you care about as clocks, and finds the hours a meeting could actually happen in. All of it runs on your phone.
There is no account, no sign-up, no cloud and no server of ours anywhere. We never see which cities you added or who you are meeting.
The app does not know where you are. It has no location permission of any kind. It reads your device’s time zone setting — the one you or your phone chose, which is a setting and not a position — so it can tell you what time it is where you are. A time zone is a region the size of a country; it is not a location, and the app never asks for one.
The whole time-zone database is inside the app. Nothing is looked up online, so conversions work in airplane mode, on a plane, and in a country where your data does not.
The only data that leaves your device is what Google AdMob needs to show ads, and none of it is anything about your zones or your meetings.
com.dashfusion.listtimezone)Everything is written to this app’s private storage, which no other app on your phone can read:
Europe/London, the label you typed for it, its position in your list,
whether it is included in the meeting view, and the working hours you set for
itThat is the whole list. There is no name, no email, no address, no photograph, no location and no contact anywhere in it, because the app never asks for any of them. A label is a word you typed for your own benefit — Mum, the Berlin office — and the app has no idea what it refers to.
We hold no copy of any of it. There is no analytics SDK in this app, no crash reporter of our own, and no telemetry.
The app also opts out of Android’s cloud backup and device-to-device transfer, so your list is never copied into Google’s backup service. That is a deliberate trade and you should know which way it cuts: nothing is stored off your phone, and uninstalling the app, or losing the phone, loses your list. Use Save a copy before you switch phones — it is the intended way to move your data, and it is never behind an ad.
Worth stating plainly, because apps in this category commonly do these things:
You can save a copy of your zones and settings to a file you choose, and restore one back. A saved file leaves the app’s protection: it is written where you point it, in a readable JSON form other apps can open. The app tells you this before it writes anything.
Restoring replaces what is in the app — it does not merge — and the confirmation says so before anything is overwritten.
The file is chosen through Android’s own document picker, which hands the app that one file and grants it nothing else. The app holds no storage permission.
The app is supported by ads served by Google AdMob. Ads are the only reason the app needs an internet connection at all; every conversion, clock and meeting calculation works fully offline.
The app shows no banner ads, no native ads and no ads on launch. The only moment an occasional full-screen ad can appear is after you have copied or shared an answer — the point at which the thing you came for has already left the app and is on your clipboard or in a message. Never while you are reading a clock, never while a conversion is on screen, and never on the way into anything. There is also an optional rewarded video you can choose to watch to switch ads off for 24 hours.
To serve ads, Google receives data from your device, which may include your
device’s advertising identifier (AD_ID), coarse location inferred from your
IP address, device and app information, and ad-interaction data. It does not
receive your zone list, your labels or anything else from inside the app.
Google’s processing is done as an independent controller under its own
policies:
Where required by law, the app shows Google’s User Messaging Platform consent form before ads are initialised, and records your choice. In the EEA and the UK you are asked about personalised advertising; in covered US states you are offered the opt-out required there. You can change your decision at any time from Settings → Ad privacy options, and if you decline, every feature of the app continues to work exactly as before.
None. We operate no servers, no accounts and no analytics. We have no database with your name in it and no way to identify you or your device. We do not sell or share personal information, because we do not have any.
The app applies the IANA time-zone rules that ship inside it to the moment you picked. Those rules change when governments change them — a country moving its clocks, or abolishing the change altogether — and an app can only be as current as its last update. When a rule changes, the corrected rules arrive in an update of the app.
The app also tells you when a local time you typed does not exist or happens twice, which is what the clocks going forward and back actually mean. That is information about the calendar, not advice: for anything that matters legally or contractually, check the time with the person you are meeting.
AD_ID) — required by Google Play for apps that serve
ads; used by AdMob as described above.That is all three of them, and there is no fourth. The app requests no location, no notifications, no camera, no contacts, no photo or media access, no storage permission, no calendar and no exact-alarm permission.
Five more permissions are merged into the final app package by the libraries the app is built on, so the list Google Play shows you is longer than the three above. They are the three Android Ad Services permissions, plus wake-lock and foreground-service, all of which come from the Google Mobile Ads SDK. None of them is a permission Android stops to ask you about, and none is used by any code we wrote.
This app is not directed at children under 13 and is not designed for use under the COPPA framework. We do not knowingly collect personal information from children — as described above, we hold no personal data at all.
If we change this policy we will update the Last updated date above and publish the new version at this URL. Material changes will also be noted in the app’s release notes on Google Play. This policy is versioned publicly in the Dash Fusion privacy repository, so any change is visible in its history.
