Privacy Policy

Overview

LTE Discovery turns your Android phone into a cellular signal analyzer. To do that — and to build community coverage maps — the app reads radio measurements from your device and, with your permission, the location where each measurement was taken. We collect the minimum needed to provide these features and we never sell your name, email address, account details or device identifiers.

Information we collect

• Cellular measurements. Signal metrics (RSRP, RSRQ, SINR), network generation (2G–5G), band / EARFCN / ARFCN, bandwidth, and cell identifiers (GCI, PCI, TAC, PLMN / carrier).
• Location. When you grant location permission, the approximate or precise coordinates of a measurement, so it can be placed on a map. You can revoke this permission at any time in Android settings; the app still functions, without map placement.
• Device & app info. Device make and model, Android version, and app version, used for compatibility and diagnostics. These describe the hardware and software, not you: they are not personal identifiers, are kept when data is anonymized, and are included in our de-identified data products.
• Account (optional). If you sign in with Google, your email address and a Google account identifier, used only to associate your saved logs with your account.
• Commercial API account (optional). If you create a Coverage Intelligence organization, we store its name, billing email, accepted terms version/time, hashed API credentials, and aggregate request/usage records. Plaintext API keys are shown once and are not stored.
• Purchase / entitlement status (signed-in only). If you're signed in, the app reports what it has determined you own (e.g. Pro, an active subscription) to our server, so support can look up your purchase history and to prepare for account continuity on future platforms. This is a record, not a control — nothing reads it back to grant or restrict access; Google Play remains the actual record of your purchase. We rely on our legitimate interest in operating account support for this.
• Speed tests (optional). If you turn on speed tests in the Android app, a test measures download and upload speed, latency and jitter, and sends the result to us with the network type (Wi-Fi or cellular), concurrent cellular signal and cell information, device model, app version, the test server location, your location (only if location permission is granted) and your network operator, derived from your IP address without keeping the raw IP in that attribution. Cellular tests ask for your consent first because they use mobile data. We use results the same way as other measurements: to improve measurement quality and coverage data and, in de-identified form, in our network data products (see “How we share it”). They stay off the public coverage map until they are validated. You can also send optional feedback (a rating and, if offered, text). Speed tests are available only in selected countries, and we may limit where and to whom they are offered while we evaluate them. Country eligibility is determined from your IP address using IP geolocation from DB-IP (IP Geolocation by DB-IP). You can turn speed tests off and delete your speed test results at any time, from any country. When you delete your speed test results or your account, they are kept only in anonymized form that can no longer be associated with you. To find and fix problems, the app also sends a technical log of each test attempt, including attempts that fail, are refused or are interrupted: the steps taken, their timing, the data used, error types, the network type and the app's test settings. It never contains your location, IP address or Wi-Fi network name. These logs are kept for 90 days and are anonymized when you delete your speed test results or your account.
• Diagnostics. Crash reports, error logs and app usage events (for example, which screens are opened and whether a speed test completed), to keep the app stable and improve it.

How we use it

• Display real-time signal information on your device.
• Save your measurement logs so you can review them over time.
• Build aggregated, anonymized coverage maps. Map tiles are only shown when they combine readings from multiple measurements; individual readings are never shown on the public map.
• Provide, secure, meter, support, and bill for optional commercial access to Coverage Intelligence data products.
• Diagnose problems and improve the app.

How we share it

We use the measurements and speed test results people contribute to build coverage maps and other network data products, which we publish and may license to businesses. We never sell information that identifies you, and we never include it in the data we publish or license: your name, email address, account details, unique device identifiers (such as IMEI, serial number, MAC address or advertising ID), install identifiers, IP address or Wi-Fi network names. These identifiers are removed before any measurement or speed test data leaves LTE Discovery, and we do not collect Wi-Fi network names (SSID or BSSID) at all. We maintain this data in de-identified form, do not attempt to re-identify it, and contractually prohibit the businesses we license it to from re-identifying it. We also share data with service providers strictly to operate the service (cloud hosting and storage, identity, speed test servers (Cloudflare), website analytics, and Stripe/Link for commercial billing when used), and when required by law. For Managed Payments, Link acts as merchant of record and receives billing, tax, payment, transaction-support, and subscription-management details. Speed test traffic goes to test servers operated by Cloudflare, Inc., which receives your device’s IP address and the test traffic in order to run the test; Cloudflare does not receive your cellular identifiers or location.

Cookies & website analytics

On our website (ltediscovery.app) we use Google Analytics 4 (provided by Google LLC) to understand aggregate usage — pages viewed, approximate region, referring site, and device/browser type. This uses cookies and sends data to Google, including to servers in the United States. The website sets no advertising cookies.

Analytics is governed by your consent (Google Consent Mode). Visitors in the EEA and the UK are opted out by default — no analytics cookies are set until you choose “Accept” on our cookie banner. You can change or withdraw your choice at any time via the “Cookie settings” link in the website footer. Declining analytics does not affect any app or website functionality. See Google’s Privacy Policy and the Google Analytics opt-out.

For our commercial Coverage API, we also keep a first-party record of how a business account or sales inquiry found us — the campaign tags in the link, the referring site’s domain and the landing page (no full URLs or personal details). Advertising click identifiers (e.g. from Google or LinkedIn ads) are kept only if you have accepted analytics, and are deleted after 90 days.

Data retention

Measurement logs are retained to power coverage maps and your personal history. Account information is kept until you delete your account. After an account is deleted, its contributed measurements remain only in anonymized form. Older raw data is moved to cold storage and aggregated. Commercial account deletion revokes API keys and deletes the Stripe customer; transaction or tax records may be retained where law requires.

Where your data is stored

LTE Discovery is operated by Simply Advanced LLC in the United States, and the data you contribute is stored and processed on servers in the United States. Speed tests run on a global network that connects you to a nearby server, and results are then stored in the United States.

If you use LTE Discovery outside the United States, your data is transferred to the United States, which may not offer the same level of data protection as your country. The US has no single comprehensive privacy law; protections come from federal and state laws such as the California Consumer Privacy Act. By turning on data contribution or speed tests, you agree to this transfer.

We protect your data with encryption in transit, restricted access, and contractual protections with the service providers that help us run LTE Discovery. Currently, the data products we license to businesses contain only data recorded in the United States.

Your rights & choices

• Revoke location or other permissions anytime in Android settings.
• Manage website analytics cookies anytime via the “Cookie settings” link in the footer (EEA/UK visitors start opted out until they accept).
• Request access to, or deletion of, your account and associated data (GDPR / CCPA). In the app, use the account screen's delete option, or email us. When you delete your account or ask us to erase your data, we delete your account information and permanently remove the link between you and the measurements you contributed. Those measurements are kept only in anonymized form that can no longer be associated with you, and they continue to contribute to coverage data.

Children

LTE Discovery is not directed to children under 13, and we do not knowingly collect their personal information.

Changes

We may update this policy; we will revise the “last updated” date above and, for material changes, provide notice in the app.
