Speed Tester · last updated
1. Summary
Speed Tester (“the app”) is an internet speed measurement utility published by Cool App Helpdesk.
- The developer collects no personal data and operates no servers.
- Speed measurements are performed by exchanging test traffic with well-known public endpoints (Cloudflare, Hetzner, OVH); your public IP is visible to those endpoints during the test (see section 5).
- The app displays advertising provided by Google AdMob, which processes a limited set of device data on its own (see section 5).
2. Data we collect
None. The developer does not collect personal data, telemetry, identifiers, device information, IP addresses, or usage analytics. There are no user accounts and the developer operates no servers that the app communicates with.
3. Data stored on your device
| Item | Where | Sent off device? |
|---|---|---|
| Most recent test result (ping, download, upload, timestamp, server name) | App memory while open; discarded when the process ends | Never |
Bundled list of public speed-test endpoints (speedtest-servers.csv) | App resources, read locally | Never (not updated over the network) |
4. Permissions used
| Permission | Reason |
|---|---|
INTERNET | Open HTTPS connections to the speed-test endpoints and to Google AdMob. |
ACCESS_NETWORK_STATE | Check that a network is available before starting a test. |
AD_ID (declared automatically by the AdMob SDK on Android 13+) | Read the advertising ID for the purposes described in section 5. |
The app does not request location, contacts, storage, microphone, camera, phone state, or any other sensitive permission.
5. Network activity and third parties
Speed-test endpoints. To measure your connection, the app opens HTTPS connections to a small number of well-known public speed-test endpoints and exchanges bytes with them:
| Endpoint | Purpose | What it sees |
|---|---|---|
speed.cloudflare.com | Latency, upload, fallback download measurement | Your public IP, standard HTTP headers (User-Agent), and the bytes exchanged during the test |
speed.hetzner.de | Primary download measurement | Your public IP and standard HTTP headers |
proof.ovh.net | Download measurement (fallback only) | Your public IP and standard HTTP headers |
These third parties operate the servers you exchange test bytes with. The app sends only the data required for the measurement — no identifiers, no account information, no device metadata beyond the User-Agent string. Each provider has its own privacy policy:
- Cloudflare: cloudflare.com/privacypolicy
- Hetzner: hetzner.com/legal/privacy-policy
- OVH: ovh.com/world/protection-personal-data
Google AdMob. The app is supported by advertising provided by Google AdMob. Two ad formats are used:
- Interstitial ads shown occasionally after a completed speed test (at most once every two tests, never within sixty seconds of the previous ad).
- Rewarded video ads shown only when you tap the optional “Watch a short video → ad-free for 24 h” button.
To serve these ads, Google AdMob processes data on its own, as an independent data controller. The data Google may receive includes:
- The device’s advertising ID (a resettable identifier you control in your device settings).
- Your IP address.
- General device information (model, OS version, language, time zone).
- Information about ad interactions (impressions, clicks, rewarded-video completion).
- An approximate location derived from your IP address.
The developer does not receive this data; AdMob shares only aggregated revenue reports. Relevant Google references:
- Google Privacy Policy
- How Google uses information from sites or apps that use their services
- AdMob & AdSense data disclosures
You can reset or delete your advertising ID, and opt out of personalised ads, at any time in Device Settings → Privacy → Ads. In the European Economic Area, the United Kingdom, and Switzerland, the app shows a consent prompt powered by Google’s User Messaging Platform on first launch where you may decline personalised advertising; non-personalised ads will still be shown.
6. Children’s privacy
The app is suitable for general audiences and is not directed at children under 13. The developer does not knowingly collect data from children. AdMob is configured to serve only non-personalised ads to users who appear, via the consent prompt described above, to be in regions where children’s privacy rules apply.
7. Data retention and deletion
The app retains the most recent test result only in memory while it is open; closing the app discards it. No persistent test history is kept. Uninstalling the app removes any remaining app data.
8. Security
All speed-test traffic uses HTTPS (TLS). The app does not store credentials or persistent identifiers locally. The app is distributed through the Google Play Store, which verifies the developer signing key on every update.
9. Changes to this policy
If any material aspect of how the app handles data ever changes, this page will be updated and the “last updated” date above will be bumped. Continued use after a change constitutes acceptance.
