BackHere
Privacy
The app runs entirely on your phone. This page lists every piece of data it touches and names the only four cases where anything leaves the device.
BackHere runs entirely on your phone. There is no account to sign in to, no server of ours holding your data, and no list of places is uploaded anywhere.
This policy covers the BackHere application on iOS and Android, and the site backhere.z-cloud.com.vn. Provided by Z-SOFT CO., LTD, Da Nang, Vietnam.
The rule
We collect no personal data. Not "collected and anonymised", and not "collected but not sold" — the app has nowhere to send data to, because we built no server for it. The table below is the complete list of what the app touches.
One row at a time
What the app holds, where it is held, and whether it leaves the phone
What most readers actually came for is the last thing in every row: does it leave the phone — rather than a sentence buried somewhere in a paragraph.
| What it is | Where it is kept | Does it leave the phone? |
|---|---|---|
| Saved places — name, category, coordinates, note, expiry | On your phone | Stays on the phone |
| Photos attached to a place | On your phone, in the app's own space — not in your photo library | Stays on the phone |
| Where you are right now | Used only while the app is open, to work out the direction and the distance. No route is recorded. | Stays on the phone |
| Settings — language, units, map style, light or dark | On your phone | Stays on the phone |
| The part of the map on screen | Sent to Apple (on iPhone) or to OpenFreeMap (on Android) to fetch the map picture | To draw the map |
| The spot whose address is being looked up | Sent to the address lookup built into your phone — Apple's on iPhone, Google's on Android | Only when online |
| The text you type into address search | Sent to Photon — an open-source address search built on OpenStreetMap data, run by komoot | Only when you search |
| A location you choose to send to someone | Goes through the messaging app you pick, as a map link | Only when you press send |
Those last four rows are everything that leaves the phone, and none of them carries your list of places, your notes or your photos.
The four cases where something leaves the phone
- Map imagery. On iPhone the map is Apple's own; on Android the map pictures come from OpenFreeMap, an open mapping service. Each request asks only for the part of the map on screen, the way a browser asks for a picture. No account, and none of your saved places, goes with it.
- Turning a coordinate into an address. When the app shows the nearest address for a saved spot, that coordinate goes to the address lookup built into your phone. We do not run this service and never receive the result — it passes between your phone and Apple or Google under their own policies. With no connection the app shows coordinates instead of an address.
- Address search. When you type into the search box on the map, what you typed goes to Photon — an open-source search service built on OpenStreetMap data and run by komoot — along with a rough position so that nearby results come first. It is sent when you pause, not on every keystroke. We do not run this service, never receive your query, and the app sends no name, no device id and no list of your places with it. Type nothing and nothing is sent.
- When you choose to send a location. The app builds a map link and hands it to the messaging app you pick. From that point the content is between you and the person you sent it to; we neither see nor store it.
Buying Pro
The transaction is handled entirely by the App Store and Google Play. We never see your name, your card or your billing address — the app asks the store exactly one question: has this account bought Pro? The Restore button asks that same question again on a new phone.
Permissions the app asks for
- Location while using the app — required; without it nothing can be saved and nothing can be walked back to. The app does not ask for background location: it does not follow you while it is closed.
- Camera and photo library — asked for at the moment you add a photo to a place, never when the app opens. A chosen photo is copied into the app's own space; the app does not read the rest of your library.
Beyond those two the app asks for nothing: no contacts, no microphone, no push notifications, no device id.
What this app does not have
No account. No analytics and no automatic crash reports. No advertising and no ad network. No cross-app tracking. Nothing sold and nothing shared — because there is nothing to sell.
Your operating system's backup
Worth stating plainly, because it is outside our control: if you have iCloud backup or Google backup switched on, your operating system may copy the app's data into that backup. That is done by Apple or Google, under your settings and their policies, and you can turn it off in your phone's backup settings.
This website
backhere.z-cloud.com.vn carries no advertising and sets no tracking cookies. As every web server does, its server keeps ordinary access logs — IP address, page requested, time — used to operate the site and block abuse, not to build a profile of a reader.
Children
The app is not directed at children under 13, and it collects personal data from nobody, of any age.
Deleting data
Everything the app stores can be deleted from inside it: one place at a time or the whole archive, and photos individually. Uninstalling the app removes every place and every photo with it.
Because we hold nothing, there is no "data deletion request" to send us. If you need that confirmed in writing, write to us and we will reply.
Changes
As the app changes, this policy is updated on this page with its date. If a change ever makes data leave the phone in a new way, it will be stated in that release's "What's new" rather than edited in quietly.

The strength is also the risk
No server holds a copy of your data, so nobody — including us — can read your list of places. The other half of that same sentence: losing the phone or uninstalling the app loses the list, and we cannot restore it for you. Switch on your operating system's backup if you want a safety net.
