Lotstamp Privacy Policy

Effective date: 6 October 2026

Who we are

Lotstamp is a mobile app for Android (and iOS where offered), published by Delix Pty Ltd, New South Wales, Australia ("Delix", "we", "us"). This policy explains what information the app accesses, how it's used, who it's shared with, how long it's kept, and how you can control or delete it.

Privacy contact: info@delix.com.au

The short version

Delix itself collects no personal information. No account and no sign-up. No ads, no analytics, no tracking.
Your photos, videos, notes, logo and PDF reports stay on your phone. Delix runs no server for the app and never receives your photos or other content.
To print a street address on your photos, the app sends your GPS coordinates to the address-lookup service you choose in Settings: OpenStreetMap Nominatim (default) or your device's built-in geocoding service (Android's geocoder, or Apple's on iOS). BigDataCloud is only used as a backup for your current location. You can turn this off in Settings.
When you make a PDF report with the site map switched on (the default), the app downloads map images from OpenStreetMap for the area around your photos. You can switch the map off when you export.
Content only leaves your phone in other ways when you choose to share it or open a location in a maps app, or through your device's own backup if you have it switched on.
Optional Lotstamp Pro subscriptions are bought and managed through Google Play. Google handles payments; Delix never sees your payment details.

What the app accesses on your phone, and why

The app asks for permissions only when a feature needs them. You can allow or refuse each one, and change your mind at any time (see "Your choices and permissions" below).

Permission or data	Why the app uses it
Camera	To take site photos and videos.
Microphone	To record sound with videos. It's only used while you're recording a video.
Location (precise or approximate)	To stamp the GPS coordinates, altitude, accuracy and street address on photos and videos, and to show the live stamp in the camera. Location is only used while the app is open on screen. The app doesn't use location in the background.
Compass / motion sensors	To show the compass direction on the stamp, where your phone supports it.
Photos you pick	When you choose "Add from gallery" or upload a logo, the system photo picker gives the app only the photos you select (Android's photo picker, or the iOS photo picker where offered). The app can read the date and GPS details stored in those photos to fill in the stamp.
Storage / files	To save stamped photos, videos and PDF reports to locations on your phone (for example Pictures/Lotstamp, Movies/Lotstamp and Documents/Lotstamp on Android).
Internet	Only for the street-address lookup and the report map images described below.

Information that stays on your phone

All of the following is created and stored only on your device, inside the app's private storage or in the locations you save to:

photos and videos (including the sound recorded with videos), original and stamped versions, thumbnails and your markup;
the stamp details: date and time, GPS coordinates, altitude, compass direction and address;
what you type: company, project, details, notes, report titles and "prepared by" names;
defect and punch-list items (title, category, priority, assignee, due date, status, close-out notes and linked before/after photos) and the folders you create;
your logo image, settings and a small cache of recent address lookups;
PDF reports you create.

Delix has no access to any of this information.

Information that leaves your phone

1. Street-address lookup (optional, on by default)

When Settings → Street address is set to OpenStreetMap or Phone and the app has a location fix, the app sends the latitude and longitude to:

OpenStreetMap Nominatim, run by the OpenStreetMap Foundation: https://osmfoundation.org/wiki/Privacy_Policy
Your device's built-in geocoding service (if you choose "Phone"): on Android, the Android geocoder, handled by your phone's location services (on most phones, Google); on iOS, Apple's geocoding service. That provider's privacy policy applies.
BigDataCloud, only for your current location and only if Nominatim doesn't answer: https://www.bigdatacloud.com/privacy-and-cookie-policy

Like any internet request, this also passes on your phone's IP address and basic technical details (such as the app or browser version and the time of the request). The services send back an address, which the app stores on your phone. No photos, names, project details or other content are sent. BigDataCloud says it uses the coordinates together with the IP address, anonymously, to improve the accuracy of its IP-location data. These organisations handle the data under their own privacy policies and may process it outside Australia.

To stop this, set Settings → Street address to Off (you can type the address yourself), or don't give the app location permission. Everything else in the app keeps working.

2. Site map in PDF reports (optional, on by default)

When you export a PDF report with Site map switched on, the app downloads map images ("tiles") from OpenStreetMap's tile servers, run by the OpenStreetMap Foundation (https://osmfoundation.org/wiki/Privacy_Policy), for the area covering the photos in the report. Because the app asks for the tiles for that area, the request shows roughly where your photos were taken, along with your phone's IP address and basic technical details (such as the app version and the time of the request). No photos, names, project details or other content are sent. The map is drawn on your phone and embedded in the PDF.

To stop this, switch off Site map in the export options. The app can also draw a simple offline plot without downloading anything.

3. When you choose to share or open something

Share sends the photos, videos or PDF you selected to the app you pick (for example email, WhatsApp or Google Drive). From then on, that app's privacy policy applies.
Open the location in a maps app ("Open in Google Maps") passes the photo's coordinates to Google Maps (https://policies.google.com/privacy), in the Google Maps app or your web browser, or to another maps app your device uses for map links (for example Apple Maps on iOS: https://www.apple.com/legal/privacy/). From then on, that provider's privacy policy applies.

Remember that stamped photos and videos show location, date and time in the image itself, so anyone you share them with can see that information.

4. Device backups (controlled by you)

Device backups (Android backup, or iCloud/device backup on iOS) may include the app's data (for example settings and saved items) according to your device settings, under the backup provider's terms (Google or Apple). Delix can't access these backups. You can manage or switch off backups in your device's settings.

5. Lotstamp Pro subscriptions (Google Play)

Lotstamp is free to use, with optional Lotstamp Pro subscriptions sold through Google Play. If you subscribe, Google handles the payment and your purchase history under the Google Play terms and Google's privacy policy (https://policies.google.com/privacy). Delix doesn't receive your payment details and runs no server for subscriptions: the app asks Google Play on your phone whether your subscription is active and keeps a small note of the result on your phone so Pro keeps working offline. You can manage or cancel your subscription at any time in Google Play.

What we don't do

We don't collect, receive or store your personal information on our own systems.
We don't sell, rent or trade personal information.
We don't show ads or use advertising IDs, analytics, crash-reporting or tracking tools.
We don't require an account.

Your choices and permissions

You can allow or withdraw the app's access to the camera, microphone, location and photos at any time in your device settings (on Android, Settings → Apps → Lotstamp → Permissions; on iOS, Settings → Lotstamp). Withdrawing a permission stops the related feature; the rest of the app keeps working.
You can switch off the street-address lookup (Settings → Street address → Off) and the report map (Site map in the export options) at any time.
Because the app doesn't collect information for Delix, there's no consent for us to record or withdraw beyond these settings and permissions.

Keeping or deleting your information

Information in the app stays on your phone until you delete it: delete individual items in the gallery, or use Settings → Delete all photos.
Uninstalling the app removes its private storage. Files you saved outside the app (for example to shared folders such as Pictures, Movies or Documents) or shared with others are not removed. Delete them with your phone's Files, Gallery or Photos app. Copies in your device backups are kept according to your backup settings.
Delix doesn't hold your information, so there's nothing for us to delete. If you'd like help deleting data from the app, email info@delix.com.au. For data kept by the address-lookup and map services, see their privacy policies or contact them directly.

Security

Address lookups and map downloads use encrypted connections (HTTPS). Your content is protected by your device operating system's app sandbox (Android or iOS) and your phone's own security (screen lock, encryption). Files saved outside the app can be seen by other apps you've given photo or file access to. Please keep your phone secure.

Children

The app is a work tool for adults in construction and the trades. It isn't directed at children under 18, and we don't knowingly collect information from children.

Your rights and complaints

Because Delix doesn't hold personal information collected through the app, there's normally nothing for us to give you access to or correct. If you have a question or complaint about privacy, contact us at info@delix.com.au. We'll respond within 30 days. If you're not satisfied, you can contact the Office of the Australian Information Commissioner (https://www.oaic.gov.au).

Changes to this policy

If the app's data practices change (for example a new feature or service), we'll update this policy and the effective date, and where appropriate tell you in the app or on the app store listing (Google Play or the App Store).
