FPS Monitor Privacy Policy

Last updated: 16 October 2026

This policy covers the Android app com.amanyt.fpsmonitor, published on Google Play asFPS MONITOR - GPU FPS TRACKER by AMX Dev.

Summary

  • No account and no sign-in.
  • What the app measures stays on your phone.
  • A session you share as a link is sent to our website, fpsmonitor.app.
  • Ads are served by Google AdMob and Liftoff Monetize. Purchases are handled by Google Play.

Data Stored on Your Phone

  • Session recordings: the app you measured, the date and length, your phone's model, and each second's frame rate, frame times, battery, temperature and CPU readings.
  • The links you share, with the key that deletes them.
  • Your settings and the games you pick.
  • Your Pro status and when Google Play last confirmed it.
  • A wireless debugging key, if you start FPS Engine that way.

None of this leaves your phone, except a session you share. If Android backup is on, Android may include it in your backup, except frame timing files and the wireless debugging key.

Data Shared With Others

  • Google AdMob: your advertising ID, IP address, device model, Android version and ad interactions, to show ads.
  • Liftoff Monetize: an ad network AdMob uses to fill some of the ads. It receives your advertising ID, IP address, device model, Android version and ad interactions, to show ads.
  • Google Play: your purchases. The app never sees payment details. A one-way hashed ID of your phone is sent with a purchase to help Google prevent fraud.
  • Our website: the session reports you choose to share, and a version check each time the app opens. Like any website, it sees your IP address. We do not store it.
  • What is sent: the game's name and package name; your phone's maker, model, chip and Android version; the session's date and length; the report's figures and charts, including frame rate, frame times, janks, battery, temperature, CPU use and the names of the game's busiest threads; and the app's version.
  • Never sent: your name, email, advertising ID or other device identifier, your location, your list of apps or the time of day.
  • Who can see it: anyone with the link. Links are not listed publicly and ask search engines not to index them.
  • How we may use shared reports: AMX Dev may use shared reports, and figures combined from many of them, to promote FPS Monitor and to publish performance comparisons of phones and games, such as rankings or a community page. A report contains nothing that identifies you. A deleted link is left out of anything we publish after it is deleted.
  • How long it stays: until you delete it. We may remove a link that breaks our terms, if the law requires it, or if the service closes.
  • Deleting it: from the link's menu on the session report, or by deleting the session. It stops working within 10 minutes and leaves our backups within 30 days.
  • Reporting a link: use Report on the shared page, or email [email protected].

FPS Engine

FPS Monitor reads frame timing through FPS Engine, a process with the same access as Android's debugging shell. It is not root. You start it with wireless debugging, ADB or Shizuku, and stop it in Settings or by restarting your phone.

It reads frame timing and layer names from Android's display system, the app in the foreground, CPU use and clock speeds, and temperatures. It makes no network connections and talks only to FPS Monitor.

Permissions

  • Display over other apps: shows the overlay.
  • Notifications: shows the monitoring notification. The app cannot read yours.
  • Foreground service: keeps monitoring running while you play.
  • Internet and network state: ads, purchases, shared links and the version check.
  • Google Play billing: sells Pro.
  • Advertising ID, basic phone state and wake lock: added by Google's ads SDK.

The app can see which installed apps have a launcher icon, so you can pick your games. That list stays on your phone. FPS Monitor does not ask for location, storage, camera, microphone, contacts, call log or SMS access.

Ads

Ads are shown inside the app by Google AdMob, which fills some of them from Liftoff Monetize. Where the law requires consent, such as in the EEA and the UK, you are asked before personalised ads are shown, and you can change your choice in Settings, under Privacy choices. See the Google Privacy Policy, how Google uses information from apps that use its services and Liftoff's privacy policy. You can reset your advertising ID in Android's settings. Pro removes ads.

Pro

Pro is a one-time purchase or a monthly subscription that may start with a free trial. Google Play handles payment, cancellation and refunds.

Security

  • Data on your phone is kept in the app's private storage.
  • Everything the app sends is encrypted with HTTPS.
  • A shared link's delete key is stored on our website only as a one-way hash.

Retention and Deletion

  • On your phone: until you delete sessions in the app or uninstall it.
  • Shared links: until you delete them, and up to 30 days more in backups. Delete links before you uninstall, since the key is kept in the app. If you lost it, email us the link and we will delete it.
  • Google: kept under Google's own policies.
  • Liftoff Monetize: kept under Liftoff's own policies.

We keep no other data about you. There are no accounts and no analytics.

Children

FPS Monitor is not directed at children under 13 and does not knowingly collect their data.

Changes to This Policy

We update this policy when the app changes in a way that affects it. The date at the top is the current version.
