GhostLab: GridSight Privacy Policy

Effective date: November 12, 2026 · Applies to the iOS and Android apps “GhostLab: GridSight”

GhostLab: GridSight lays a grid of dots over your room and logs a break when something interrupts it. It has no user accounts and no servers of our own. On iPhone and Android, the app counts how it is used through Google Analytics for Firebase, described under Usage statistics. Everything it records stays on your device unless you choose to share it.

Summary

• Usage statistics. The iPhone and Android apps count how the app is used through Google Analytics for Firebase. They never send your photos, clips, sound, logs or location.
• The camera watches the room on your device. When a break is logged, the app can save photos and a clip to its own storage. You can turn both off.
• The microphone is used only for clip sound. You can turn it off.
• Your location is never used.
• No ads and no tracking.
• No accounts and no sign-in.

The camera

• While you monitor, camera frames are compared on the device to notice changes along the grid. Frames are held in memory only as long as that takes, plus about two seconds so a clip can start just before a break.
• When a break is logged, and Trip photos is on, the app saves 4 photos. When Trip clip is on, it saves one 10 second video that starts 2 seconds before the break. Both carry a small GridSight mark. Both settings are on until you change them.
• The camera stays off until you tap Start monitoring. If you decline camera access, or turn it off later in your device settings, the app cannot monitor.

The microphone

When Clip sound is on, the trip clip records sound from the break onward. Sound is saved only inside that clip. It is on until you change it in Settings. If you decline microphone access, or turn Clip sound off, clips are saved without sound.

Depth and motion on iPhone

On iPhone, the app uses motion sensors to hold the camera view steady. On iPhone Pro models it can also use the LiDAR scanner to confirm a break, and the depth change at that spot is noted in the log. Readings are used live on the device. The Android app uses neither.

Data the app keeps on your device

• Trip photos and clips — saved in the app’s own storage and listed in the Sessions library.
• Saved sessions — if you keep a session, it is a small file of times, grid cells, strengths, and any depth changes. It contains no pictures or sound.
• Settings — your grid, sensitivity, and capture choices, kept so the app opens the way you left it.

On iPhone, these files can be seen in the Files app under GridSight, and like other app documents they are included in your device backup. On Android, the app’s files are left out of device backups.

Deleting your data

You can delete trip media and kept sessions in the Sessions library. Deleting the app removes everything it stored on the device, though a device backup you made earlier may still hold a copy on iPhone.

Sharing

Your photos, clips and sessions leave the app only when you share them. The share sheet sends a photo, clip, or session wherever you choose. Once it leaves the app, the app or person you shared it with decides what happens to it.

Usage statistics

GhostLab: GridSight uses Google Analytics for Firebase on iPhone and Android to count how the app is used, so we can see how many people start monitoring, start the trial or unlock the app, and where they stop.

It records:

• What you do in the app, in general terms: finishing the tutorial, starting to monitor and which mode you used, keeping a session and how long it ran, opening the share sheet and the kind of item (a session, a trip, a clip or a photo), the app you shared to when it is a well-known one such as TikTok or YouTube, opening the unlock screen, starting the free trial, and how an unlock purchase ended, with its price and currency.
• An app-instance identifier that Firebase creates for GridSight on your phone. It is not linked to your name, your Apple or Google account, or your phone’s advertising identifier. It resets if you delete the app, or on Android if you clear its data.
• Basic device and app details: phone model, iOS or Android version, app version, language, and country.
• Your approximate area, such as your city and country, which Google works out from your IP address. Google Analytics does not store the IP address.

It never records camera frames, your photos, clips or their sound, your break log, file names, anything you type, or your location from GPS. GridSight does not collect your phone’s advertising identifier. On Android the permission is removed from the app and collection is switched off. The iPhone app never asks to track you and leaves out the part of Firebase that can read the advertising identifier, and it does not collect the iPhone’s vendor identifier either.

In the European Economic Area, the United Kingdom, and Switzerland, the app does not send usage statistics on iPhone or Android.

Google processes this information for us as a service provider. We have turned off Google’s options to use it for its own products or for advertising, and we do not link it to Google Ads. The recorded actions are kept for 2 months, and the identifier until 2 months after you last use the app. Then Google deletes them automatically.

What we do not do

• We do not sell personal data.
• We do not run advertising SDKs or trackers. The app’s only analytics is the usage statistics described above.
• We do not upload your photos, clips, sound, or sessions.
• We do not use your location.

Children

The app carries the age rating shown on its store page. We do not knowingly collect personal information from children, and the app collects no personal information from anyone. The app’s usage statistics are described above.

Changes

If our practices change, we will update this page and the effective date above before the change takes effect.
