Privacy Policy – Roamdex

Last updated: October 13, 2026

Roamdex ("the app") is a personal journal for remembering the people you meet. This policy explains what happens to the information you put into it.

The short version

The developer collects nothing. There is no account, no server of ours, no analytics, no advertising and no tracking. Everything you enter stays on your device – unless you export it, turn on Google Drive sync, or have Android's own device backup switched on. Drive sync and Android backup keep a copy under your own Google account. A few optional features use services built into your phone or public map services, as described below.

What the app stores

The information you choose to enter about people – names, contact details (for example an Instagram username or phone number), where and when you met, meetups, notes, birthdays, photos and map coordinates – is stored on your device, inside the app's private storage. It can also leave the device when you export it, turn on Google Drive sync, or have Android's own device backup switched on (see below). The developer never receives, sees or has access to it.

Google Drive backup & sync (optional, Pro)

If you connect Google Drive in Settings, the app copies your journal (people, photos and the list of people you deleted, so deletions reach your other phones too) into the app's private, hidden folder in your own Google Drive ("app data folder"), and reads it back to keep your phones in sync. It's sent directly from your phone to Google over an encrypted connection.

• The app asks only for access to its own hidden folder. It can't see, open or change any of your other Drive files.
• The developer has no access to your Drive or to this copy; it's stored by Google under your account and Google's privacy policy.
• Settings → Google Drive → Disconnect stops syncing and gives up access. You can choose to delete the copy from Drive at the same time. You can also remove the app's access any time at myaccount.google.com → Security → Third-party connections, or delete the hidden data in Google Drive → Settings → Manage apps.

Optional features that use other services

• “Use my location” – only when you tap it. The app asks Android for your approximate location (not precise GPS) and turns it into a place name such as “Hanoi, Vietnam” using Android's built-in geocoding service, provided by Google as part of the phone's system. The coordinates are saved with that person on your device. If you already allowed location, the add-person form can offer your current place and the place picker can start there without asking again.
• Places on the map – while you type a place (where you met, or the town someone is from), the text typed so far is sent to Photon (photon.komoot.io, a place search run by komoot GmbH on OpenStreetMap data) to suggest matching places; it sees the text and your device's IP address, nothing about the person. If it has no answer, the phone's built-in geocoding service is asked instead, and the name under a pin in the place picker also comes from that service. These searches run only while online. (The web version uses OpenStreetMap's Nominatim service where the app uses the phone's.)
• Map – map images come from OpenFreeMap (openfreemap.org). Like any website, their servers see your device's IP address when the map loads; no information about the people in your journal is sent.
• QR code scanning – uses Google's code scanner from Google Play services. The camera picture is processed on your phone; the app only receives the text of the scanned code.
• Sharing into the app – when you share a profile link from another app (for example Instagram) to Roamdex, the app receives only the text you shared.
• Phone contacts – the system picker shares only the people you choose: their name, available phone numbers, e-mail addresses and photo, and, where the picker provides them, birthday, nickname, hometown and country, recognised website/profile links and notes. Android 17’s system picker currently provides birthday, nickname and postal address details, but not website links or notes. The app does not request permission to read your address book. Some phones share only the name; a second picker can share one phone number.
• Contacts files – a contacts file you open or share is read on your device. Only the people you tick are added to your journal. A file containing one person opens a form for you to review and save. No address-book permission is requested.
• My card – your own card (the name, contacts and hometown you choose to put on it) is shown as a QR code and a link. The details are packed into the link itself, after the “#”, which browsers never send to a server: the card page on roamdex.net reads them on the viewer's device and stores nothing. Anyone you give the link or QR code to can see what's on your card, so only add what you're happy to share.

Purchases

Pro is a one-time purchase handled entirely by Google Play. The app only learns whether Pro was bought; it never sees your payment details.

Permissions

• Approximate location – requested only when you tap “Use my location”. An existing grant can also provide the current-place suggestion and the place picker’s starting point.
• Notifications – only if you turn on reminders. Birthday and catch-up reminders are scheduled locally on your device.
• Camera and photos – the app uses the system camera and the Android photo picker, so it only ever sees the single photo you choose. Photos are resized and stored inside the app.
• Fingerprint, face or screen lock – only if you turn on app lock. Android checks it; the app never sees any biometric data. While app lock is on, the app's content is hidden in the recent-apps view and screenshots are blocked.

Backups and sharing

• Export – when you export a backup or a calendar file, the app creates the file and hands it to the destination you pick in the system share sheet (for example Google Drive or email). What happens to it from there is governed by that service.
• Android backup – if you have Android's device backup turned on, Android can include your journal, photos and preferences in your personal Google backup, as it does for other apps. You can turn this off in your phone's settings.

Links to other apps

Tapping a contact (for example an Instagram handle or a phone number) opens it in the corresponding app or website. Those services have their own privacy policies.

Children

The app is not directed at children under 13 and does not knowingly collect information from anyone.

Deleting your data

You can delete any person at any time, or everything at once in Settings → Delete all data. Uninstalling the app removes all of its data from your device.

Changes

If this policy changes, the updated version will be published at this address with a new date.
