Privacy Policy
Applies to the Android app Sentrio IP Cam (package ID com.sentrio.ipcam). The website gremlincode.de has its own privacy policy.
1. Controller
The controller within the meaning of the General Data Protection Regulation (GDPR) is:
Marc Schrimpf
Stuttgarter Str. 106
70736 Fellbach
Deutschland
E-mail: info@gremlincode.de
2. Principle: no data transfer to us
Sentrio IP Cam turns an Android smartphone into a LAN IP camera. The app is operated entirely locally: through a web interface the smartphone itself serves on your local network (Wi-Fi).
The app sends no usage, camera, microphone or other data to us as the developer or operator. There are no analytics, tracking or crash-reporting SDKs and no servers on our side that the app communicates with. At no point do we receive or see any images, audio or other recordings from your use of the app.
3. Camera, microphone and recordings
The camera and microphone are used solely locally to produce the live stream or recordings. Recordings (video, photo, time-lapse) remain on the device by default. Data only leaves your device if you actively set this up yourself:
- NAS upload: You can configure the optional upload to your own network-attached storage (NAS) via SMB, FTP or SFTP. You define the target device, credentials and transfer path yourself; we have no access to it.
- E-mail notification: You can optionally enable an e-mail notification on motion or sound detection. It is sent via your own SMTP server that you configure — not via any server of ours.
In both cases, you alone determine the destination of the data transfer.
4. Live stream
The live video stream runs via WebRTC directly between your smartphone and the requesting browser within your local network (peer-to-peer). No third-party or our own servers are involved.
5. Purchases (Google Play Billing)
The one-time Premium purchase that removes the free usage limits is handled via Google Play Billing. Payment data is processed exclusively by Google; the app itself only receives the purchase status (Premium: yes/no) from Google. For information on data processing by Google, see the Google Play privacy policy.
6. App permissions
| Permission | Purpose |
|---|---|
| Camera | Producing the live image, video recording and photos. |
| Microphone | Audio recording and optional talk-back (two-way audio). |
| Network / Wi-Fi | Running the local web server, providing the live stream, and optional NAS upload and e-mail sending. |
| Foreground service & notifications | Keeps the local server running in the background and shows its status. |
| Battery optimization exemption | Allows continuous streaming/recording even with the display off. |
7. Your rights as a data subject
Since the app transfers no personal data to us, its use generally involves no processing to which data-subject rights against us could apply. Insofar as personal data is nonetheless processed, you have the following rights within the statutory framework:
- Access to the data stored about you (Art. 15 GDPR)
- Rectification of inaccurate data (Art. 16 GDPR)
- Erasure of your data (Art. 17 GDPR)
- Restriction of processing (Art. 18 GDPR)
- Data portability (Art. 20 GDPR)
- Objection to processing (Art. 21 GDPR)
- Lodging a complaint with a data protection supervisory authority (Art. 77 GDPR)

8. Changes to this policy
We adapt this privacy policy when the app's features or the legal requirements change. The version published on this page at the time applies.
