Drugs & Doses Privacy Policy

Drugs & Doses - Anesthesia is published by nrhealthtech. It is an offline educational drug-dose quick-reference for anaesthesia providers. This policy explains exactly what the app does and does not do with information, and it applies to the Android app distributed through Google Play.

The app runs entirely on your device. It does not ask you to sign in, it does not know who you are, and it never sends anything anywhere. nrhealthtech receives no data from the app — not usage statistics, not crash reports, not the values you type in.

There is no server behind this app. There is nothing for us to see.

The app saves a small amount of information in its own private storage on your device, so it opens the way you left it:

• Your drug library, including any drugs you add, edit, rename or recolour
• The last weight, age, height and sex entered in the patient bar
• Your display choices, such as which screen you last used and whether you dismissed the disclaimer

This data never leaves the device. It is not readable by nrhealthtech or by any other app.

To be explicit, the app does not collect, request or transmit any of the following:

• Names, email addresses, phone numbers or any account credentials
• Device identifiers, advertising IDs, IP addresses or installation IDs
• Location data of any kind
• Contacts, photos, files, camera or microphone data
• Usage analytics, event logs, session recordings or crash reports
• Patient-identifiable information or medical records

The app contains no advertising, and nothing in it is sold, shared or disclosed to anyone, because nothing is collected in the first place.

The app makes no network requests. All content — the drug data, the monographs, the fonts and the icons — is included in the app and loaded from your device, so it works fully offline.

The app does not ask for any permission that gives access to your personal data. It cannot access your location, contacts, storage, camera or microphone.

The app does not back up your data to the cloud. Your drug library and settings are not copied to Google Drive or transferred to a new device when you change phones. If you want to keep your edits, use the export feature described below.

The menu lets you export your drug library as a file and import it again later. This is entirely under your control: the file is created on your device and goes only where you send it using your phone's own share options — for example to your own files, email or messaging app.

nrhealthtech does not receive exported files and has no way to access them. Once you share a file with another app or service, that app's or service's own privacy policy applies to it.

This app is a professional reference tool for anaesthesia providers. It is not directed at children and is not designed or marketed for use by them. No data is knowingly collected from anyone, of any age.

Because everything is stored on your device, you are in complete control of it:

• Reset the drug library — open the menu and choose Reset to reference defaults to discard your edits and restore the original data.
• Clear everything — in Android Settings › Apps › Drugs & Doses › Storage, tap Clear storage.
• Remove it entirely — uninstalling the app deletes all of its stored data from your device.

There is no data held elsewhere, so there is nothing to request, correct or erase from us. If you are in a jurisdiction granting rights of access, correction, portability or erasure, those rights are satisfied by the controls above, since nrhealthtech holds no personal data about you.

The app is distributed through Google Play. Google collects its own information when you download or update an app — for example your Google account and device details — under Google's own privacy policy, which nrhealthtech does not control and is not a party to. Please refer to Google's policy for how Google handles that information.

Separately from privacy, and for the avoidance of doubt: the app is an educational quick-reference. It is not a medical device, it has not been evaluated or approved by any medicines or medical-device regulator, and it must not be used as the primary basis for any dosing decision. The full disclaimer is shown at the bottom of the app itself.

If this policy changes, the revised version will be published at this address with a new effective date, and the app listing on Google Play will point to it. Because the app collects nothing, any change is likely to be a clarification rather than a change in practice.

For any question about this policy or about the app, email nrhealthtech@gmail.com.
