Privacy Policy

Effective date: May 13, 2025

Short version: We do not collect, sell, or share your data. All meter readings are stored locally on your device in a SQLite database. There is no cloud backend, no account required, and no advertising.

1. Who We Are

Utilify is published by Adelyons Software LLC. The app reads electric and gas utility meters via an RTL-SDR USB dongle (SCM protocol, 912 MHz) and stores all data locally on your device. Questions? contact@adelyons.com.

2. Data We Do NOT Collect

No account or sign-in is required
No meter readings or usage data are ever uploaded to our servers
No advertising identifiers (Google Advertising ID or equivalent)
No analytics or crash-telemetry sent to Adelyons
No payment card data — billing is handled entirely by Google Play
No bill photos — images captured for OCR are processed on-device and never uploaded

3. What Happens on Your Device

Meter readings (SQLite, local only)
Every SCM reading captured from your RTL-SDR dongle is written to a SQLite database stored in the app's private data directory. This data never leaves your device except via the Pro tunnel described below. Uninstalling the app permanently deletes the database.

Bill photos & OCR
If you use the bill-scan feature, the camera image is passed to Google ML Kit Text Recognition, which runs entirely on-device. The image is not uploaded anywhere by Utilify.

Meter ID broadcasting
Utility meters broadcast their readings unencrypted over radio. Utilify passively receives these broadcasts. It does not transmit anything on the radio spectrum.

4. Third-Party Network Calls

Weather — Open-Meteo (optional)
If you enter a property address, Utilify sends the city/state coordinates to the Open-Meteo open-source weather API to fetch historical temperature data for usage correlation. No account is required by Open-Meteo; no personal identifier is included in the request. This feature is opt-in: the app functions fully without an address.

Local network discovery
Utilify scans your local /24 subnet on port 8765 to discover other Utilify instances running on the same network (e.g., a phone connected to the same router). Only TCP connection attempts are made; no data is sent to the internet during this scan.

Google Play billing
Pro subscriptions ($0.99/week or $19.99/year) are processed entirely by Google Play. Adelyons receives only a purchase token from Google to verify your subscription status. No payment card details ever reach Adelyons servers. See Google's Privacy Policy.

Pro frp tunnel (optional)
If you activate the Pro remote-viewing tunnel, your device establishes an outbound connection to an frp server. This allows a viewer device to reach your meter data remotely. Adelyons does not relay or log this traffic; the frp server is either baked into the build at compile time via secure configuration or configured by you. No meter data is stored outside your device.

5. Permissions and Why We Need Them

USB — communicates with the RTL-SDR dongle over USB OTG
Camera — captures bill photos for on-device OCR scanning
Internet — weather temperature fetch (Open-Meteo) and Google Play billing
Location (optional) — geocodes a property address you enter for multi-location tracking; not used for advertising or tracking
Receive Boot Completed — on Android TV only, auto-starts the meter listener after reboot so you don't need to manually open the app
Foreground Service — keeps the RTL-SDR listener and local API server alive when the screen locks
Wake Lock — prevents the CPU from sleeping while actively decoding meter packets
Read External Storage / Read Media Images — required by the image picker library on Android 12 and earlier

6. Data Retention and Deletion

All meter readings are stored only on your device. There is no Adelyons account to delete. To remove all data, simply uninstall the app — the SQLite database is deleted with it. You can also delete individual readings or properties from within the app at any time.

7. Children

Utilify is not intended for children under 13. We do not knowingly collect any personal information from anyone, let alone minors.

8. Changes to This Policy

If we make material changes to this policy — for example, if a future version adds a cloud feature — we will update this page and revise the effective date. We will not introduce data collection silently.
