Who we are
Track Trail ("the app", listed on Google Play as "Track Trail - Blood Tracker Camera") is published by NK Tech Solutions ("we", "us"), based in . This policy explains what information the app uses, why, and the choices you have. It applies to the Android app and to this website.
Data that stays on your phone
The app's main features work entirely on your device. We do not run servers that receive this data.
Camera
The Blood Vision camera processes each frame on your phone to highlight blood-colored pixels. Frames are shown on screen and immediately discarded. The app does not take photos, record video, or send camera images anywhere.
Location
When you mark a hit spot or drop a pin, the app saves your precise GPS location with the time and pin type. Location is used only while the app is open on screen; the app does not access your location in the background. Your trail, distances and the compass are calculated on your phone.
Tracks and settings
Your tracks, pins and app settings (such as units, sensitivity and highlight color) are stored in the app's private storage on your phone. They are not uploaded to us. They may be included in your phone's own Android backup if you have device backup turned on, which is controlled by Google and your device settings.
Permissions

| Internet | Loads map tiles, shows ads, and processes purchases. |
| Vibration | Haptic feedback when you drop a pin. You can turn it off in Settings. |
The app does not request microphone, contacts, photos or background location access.
Third-party services
The app uses the following services. Each one collects information under its own privacy policy. We only receive aggregated reports from them (for example, ad earnings or the number of purchases), not your location or tracks.

Advertising and your choices
- Consent: if you are in the European Economic Area, the United Kingdom or Switzerland, the app shows Google's consent form before any ads load. You can change your choice anytime in Settings → Ad privacy choices.
- Advertising ID: you can reset or delete your advertising ID in your phone's settings (usually Settings → Privacy → Ads or Settings → Google → Ads). Ads may then be less relevant.
- Remove ads: Premium (Weekly or Lifetime) turns off all ads. Watching one optional reward video turns ads off for 12 hours.
Retention and deletion
- Delete a single track in the Tracks tab, or all tracks in Settings → Delete all tracks.
- Uninstalling the app deletes all tracks and settings stored by the app on your phone.
- Information held by AdMob, RevenueCat and Google Play is kept according to their policies. To ask for deletion of purchase data linked to your anonymous RevenueCat ID, email us at support@nktechsolutions.in.
- If you email us, we keep your message only as long as needed to help you, and then delete it.
Your rights
Depending on where you live, you may have the right to access, correct, delete, or restrict the use of your personal information, to object to processing, to withdraw consent, and to complain to a data protection authority. This includes rights under the EU and UK GDPR, the California Consumer Privacy Act, and 's Digital Personal Data Protection Act, 2023. Because we don't receive your tracks or location, most of your data is already under your control on your phone. For anything else, contact us and we will respond within 30 days.
Where GDPR applies, we rely on your consent for personalized advertising, and on the performance of a contract for processing purchases. Third-party services may transfer data to countries outside your own, under the safeguards described in their policies.
Children
Track Trail is a hunting tool intended for adults. It is not directed at children under 13 (or the minimum age in your country), and we do not knowingly collect information from children. If you believe a child has provided information through the app, contact us and we will help remove it.
Security
Your tracks are stored in the app's private storage, which other apps cannot read. Connections to third-party services use encryption (HTTPS). No method of storage or transmission is completely secure, so keep your phone locked and up to date.
Changes to this policy
If we change this policy, we will update the effective date at the top of this page. For significant changes, we will also let you know in the app.
