Controller Tester Developer: Aaron Lowe Last updated: September 19, 2026
This Privacy Policy describes how Controller Tester handles user information and your privacy rights when you use the app on iOS or iPadOS.
Controller Tester is offline by default. With one exception, described below, it does not collect, store, share, or transmit any personal information, and nothing it reads from your controllers leaves your device.
The exception is Share CT, an optional global reaction-time leaderboard. It is off unless you turn it on and shows you what it sends before the first byte leaves your phone. The app also offers controls to report a player for review or block that player’s entries on your device. A report request leaves your device only when you choose it; the app says it was sent only when the service accepts it. You can request erasure of your server-held data. The only request the app may make after you turn Share CT off is a retry of an erasure you already requested.
Controller Tester uses Apple’s GameController framework to read live input data from any game controller you connect to your iOS device, whether wired or via Bluetooth. It displays this data on your screen in real time so you can verify that buttons, sticks, triggers, and the directional pad are reporting correctly. All input data is held in memory only for as long as the app is open, and is discarded when you close the app.
Before Share CT is enabled, the app sends nothing. After you turn it off, a previously requested erasure may still retry until confirmed. Through the app, we do not collect, log, transmit, or store any of the following, whether the leaderboard is on or off:
There is no account to create and no sign-in anywhere in the app.
Share CT publishes reaction-test scores to a leaderboard that anyone can view on the web. It is opt-in. Before it sends anything, the app shows you a sheet listing every item below; if that list ever changes, the sheet is shown again and you are asked again.
When it is on, and only then, these are sent:
That is the complete list sent by the app. Your display name, scores, controller name, and a short player-id suffix are available through the board. When the service provides an opaque public player reference, that reference is also available and is used to block or report a player. It is separate from the private credential that authorizes your requests. The player id is random and is not derived from your device, Apple ID, or advertising identifier. The app does not ask for your email address or create an email account.
Reports and blocks. Report requires Share CT to be on and a board row with a public player reference. The app says a report was sent only after the server accepts it. Until the server supports reporting, the control may be unavailable or a submission will show failure. If accepted, a report is stored privately with the reporter, reported player, selected reason, submission time, and review state. It is not public, and sending it does not automatically remove anyone. The developer reviews accepted reports and decides whether to dismiss them or act on the reported player’s public entries. If private email alerts are enabled, an alert to the review owner contains a report ID and a link to the authenticated review screen, without player details or the reason. A failed email delivery leaves an accepted report available for review. You can also report offensive board content directly at lowekeyflexin@gmail.com.
Block saves a player’s public reference and display name on your device to hide that player’s entries from your view of the board. You can undo a block in the app. Blocking does not send a request to the server and does not change ranks or what others see.
Where it goes. The leaderboard is a small server run on the developer’s behalf by a volunteer, on their own hardware and home internet connection. It is not a commercial hosting provider and it is not covered by a service agreement. It is a beta, it may be unavailable at times, and the app says so wherever the board appears.
Deleting what you have sent. The app has a control in its leaderboard settings that erases your scores and player record from the live server. If the server has accepted reports involving you, deletion also removes their live report and review records and pending alerts. The app discards runs still waiting to be sent and retries the erasure until the server confirms it if the server is initially unreachable. A private alert email already delivered to the review owner may remain in that mailbox after server erasure; it contains only a report ID and review link, without a name, player reference, or reason. Contact us at the address below to ask about a delivered alert.
Backups. The server is backed up nightly and backups are kept for fourteen days. A deletion takes effect on the live leaderboard and private review queue when confirmed; a copy may persist in a backup until those backups age out.
The app contains no third-party SDKs, analytics tools, advertising networks, or tracking services, and it never has.
If you turn Share CT on, these parties are involved in delivering it:
The volunteer and Cloudflare handle Share CT requests only after it has been enabled or while the app finishes a previously requested erasure. A private email alert, if enabled, may be delivered after you turn Share CT off for a report the server accepted earlier.
Before you enable Share CT, the app makes no network requests at all. It does not connect to any servers, ours or anyone else’s. You can verify this by enabling Airplane Mode and using the app normally: every feature except the leaderboard works unchanged. Turning Share CT off stops board requests and score submissions; a previously requested erasure can still retry until confirmed.
With Share CT on, the app contacts only the leaderboard server described above, and only to register a player, send a finished trial, read the board, rename you, submit a report you choose, or erase your data at your request. The server, not the app, sends private review alerts.
The app requests Bluetooth permission only so that iOS can expose connected wireless game controllers to it through Apple’s GameController framework. The app does not scan for, connect to, or communicate with any other Bluetooth devices. Bluetooth pairing of controllers is handled by iOS itself, not by this app.
The app contains no advertising. Before Share CT has ever been enabled, no player data is sent to the server. Turning it off later stops new board requests and score submissions but does not erase data already sent; use the erasure control for that.
Share CT is off unless it is deliberately turned on. If it is turned on, a chosen display name and reaction scores become publicly visible on the leaderboard. Choose a display name that does not identify you. A parent or guardian can turn the feature off and erase everything it has sent using the control described above.
If Share CT has never been enabled, the app has sent no player data to the server. If you used it and then turned it off, previously sent data remains until you request deletion.
If you have used Share CT, the data listed above may be held, and your rights apply to it:
We do not sell personal information, share it for cross-context behavioural advertising, or use it for any automated decision-making or profiling. The legal basis for processing is your consent, given by turning the feature on after being shown the list of what it sends, and you may withdraw it at any time by turning it off.
If you have questions about how these regulations apply, you can contact us at the email below.
If this policy changes, the updated version will be posted at the same URL. Substantive changes will be reflected in the “Last updated” date at the top.
Questions about this policy, reports, or objectionable leaderboard content can be sent to: lowekeyflexin@gmail.com. If you email us, your address and message reach our support mailbox and are used to respond to your request.
