PraeGuard privacy notice
Prepared 5 November 2026 · Praescius Ltd
Controller and contact: Praescius Ltd, 82A James Carter Road, Mildenhall, IP28 7DE, UK (Company No. 16154950). Email info@praescius.org.uk.
1. Why the app processes information
PraeGuard allows a user to monitor an authorised space using their Android phone and to review events it records. The app may process microphone audio, locally generated sound classifications, movement/rotation sensor signals, screen or power-related observations, optional camera photographs, timestamps, files and incident summaries.
2. On-device processing and storage
Sound classification and incident assembly run on the device. Evidence such as WAV clips, photographs, related metadata, review labels and exports may be stored in private app storage or in a location the user selects when exporting. Praescius does not currently operate a PraeGuard cloud evidence-storage service.
3. Gmail alerts are optional
If you connect a Google account and opt into email alerts, PraeGuard uses the Gmail send-only permission to send activity summaries and, where selected and available, audio clips and photographs to the recipient you choose. This permission does not give PraeGuard inbox-reading access. The sending account's Sent mail and the recipient's mail provider may retain copies of sent messages and evidence. Standard Gmail messages are not end-to-end encrypted.
Remote alerts may be queued on the device while offline and attempted later. You can disable automatic alerts and disconnect Google authorisation. You can also revoke access from your Google account's third-party connections page.
4. Google Play billing
If you purchase PraeGuard Pro, Google Play handles the transaction and may supply entitlement information to the app so the Pro features can be enabled. Google's payment and account data practices are covered by Google's policies. Praescius does not need to receive your recordings for a purchase.
5. Data sharing
PraeGuard does not intentionally upload the monitoring evidence to Praescius. Information may be transferred to Google and the chosen email recipient when you enable remote alerts, to Google Play for billing and entitlement checks, or to whoever you choose when you export/share evidence. Web hosting providers may process routine IP, device and request metadata when you visit this website.
6. Permissions and notices
Depending on enabled features, the app requests microphone, optional camera, notification and other Android permissions. Android's microphone/camera indicators and monitoring notifications remain visible subject to device/system behaviour. The app is not intended for hidden surveillance of people without authorisation.
7. Retention, correction and deletion
Original evidence remains on the device until you choose deletion or the app/device removes it, for example by clearing storage or uninstalling. Marking an incident ignored or as your activity changes only the review/export selection. Within the app you can review evidence, export files, manage storage and delete saved evidence. Deleting local copies does not recall emails that have already been sent or recipient copies.
8. Website and support information
If you contact support, Praescius processes the information you supply to answer your request. Routine website access metadata can be processed by the hosting provider. This site does not intentionally embed third-party advertising trackers in the PraeGuard pages.
9. Your choices and rights
You can decline optional features, change app permissions in Android settings, disable email alerts, revoke Gmail authorisation and remove local evidence. If Praescius holds personal information in a support or commercial context, you may have rights under applicable data-protection law to access, rectify or erase it and raise concerns with your local supervisory authority. Contact info@praescius.org.uk for enquiries.
10. Updates
We may revise this notice as the app, provider requirements or legal obligations change. The latest version will be available at this address.
