Privacy Policy

Layra measures and stores your results only on your device, and never uploads them. It has no account and no server. Since version 1.1 it shows an ad between runs, served by Google AdMob — that is the one part of the app where data about your device leaves it, and it is described in full below.

The short version

Everything Layra measures — your sessions, reaction times, scores, and streaks — stays on your device. We (the developer) have no servers and receive none of it. Two features use the network, and both are described below: Apple’s optional Game Center leaderboard, and the ads Google serves between runs.

Information we collect

None, ourselves. There is no sign-up, no login, and no user account managed by us. Layra’s own code transmits nothing about you to anybody, and none of your results are uploaded.

The Google Mobile Ads SDK, however, collects data on the app’s behalf in order to serve and measure ads, and Apple counts that as collection by the app. Layra’s App Store privacy label therefore declares the following, all of it handled by Google rather than by us:

• Device ID (your advertising identifier) — third-party advertising
• Advertising Data — third-party advertising
• Product Interaction — third-party advertising and analytics
• Crash Data and Performance Data — diagnostics for the ad SDK

None of it is linked to your identity, and none of your reaction times, scores, or sessions are part of it.

Data stored on your device

To function as a training tool, Layra saves your activity locally on your device using Apple’s on-device storage:

• Session results and reaction-timing measurements
• Your Neural Response Score, per-game scores, and history
• Streak and progress state
• App settings and preferences
• Your ad consent choices, and how many runs you have finished since the last ad

This information never leaves your device unless you choose to use Game Center (see below). It is not accessible to us. Deleting the app permanently removes all of this data.

Advertising (Google AdMob)

Layra is free, and a full-screen ad appears on the way out of a finished run — never during one, and never while you are being timed. It is paced: at most one per three completed runs, and no sooner than 90 seconds after the last. If you are offline, no ad is requested and none is shown, and the app behaves exactly as it did before ads existed.

When an ad is requested, Google may collect and process data — your device advertising identifier, along with usage and diagnostic information — to deliver and measure it. Google’s handling of that data is governed by Google’s own policies: the Google Privacy Policy and How Google uses information from sites or apps that use our services.

Nothing Layra measures is sent to Google. Your reaction times, your Neural Response Score, your session history and your streaks are not part of an ad request.

Tracking, and your consent

Layra asks for permission to track, through Apple’s App Tracking Transparency prompt, so that the ads between runs can be personalised. Declining changes nothing about the app — every game, score and feature works identically, and you will simply see less relevant ads.

Where required, Google’s consent form is presented before the first ad. Once you have made a choice you can change it at any time in Settings → Ad privacy inside the app; in regions where that form is required, the row is always available there. You can also limit ad personalisation system-wide in iOS, under Settings → Privacy & Security → Tracking and Settings → Privacy & Security → Apple Advertising.

Game Center (optional)

If you sign in to Apple Game Center, Layra submits a single number — your best Neural Response Score — to the leaderboard, so you can compare with other players. Nothing else is submitted. This is entirely optional; the app is fully functional without it, including in airplane mode.

Game Center is an Apple service. Any data you share through it is governed by Apple’s Privacy Policy, not by us. We do not receive your Game Center identity or personal details.

Network use

Beyond ad requests and Game Center, Layra uses the network only to detect whether you are online — so it can queue a Game Center score submission for when a connection is available, and so it knows not to ask for an ad when there is no connection. No data is sent to any server operated by the developer; there are none. Google’s ad SDK is the only third-party SDK in the app.

Challenge links you share with a friend carry the whole challenge inside the link itself. There is no server round-trip and no record of who you played.

How your ranking is calculated

Any comparison Layra shows you against a wider population is computed on your device against reference data bundled with the app. Your scores are not uploaded to produce it, and it is not a live ranking of real players.

Children’s privacy

Layra is rated 4+ but is not directed to children, and we do not knowingly collect personal information from anyone, including children. We receive no data about you at all. Ads shown in the app are served by Google under the policies linked above, and any tracking is subject to the permission prompt described in Tracking, and your consent.

Data retention and deletion

All Layra data lives on your device. To delete it, delete the app. Game Center scores are managed by Apple; you can control them through your Game Center account settings. Data Google collects to serve ads is retained under Google’s own policy, and you can withdraw or change your ad consent at any time as described above.

Not a medical device

Layra is a training and measurement tool, not a medical device, and makes no health claims. It does not diagnose, treat, or prevent any condition, and no result it shows is a health claim.

Changes to this policy

If this policy changes, we will update the “Last updated” date above.
