Privacy Policy

This policy explains what Blink (“the app,” “we,” “us”) does and doesn’t do with your data. Blink is a reaction-time reflex trainer published by ISG , It’s built to be genuinely honest about this: the app trains reaction speed and hand-eye coordination at specific tasks, and makes no claims about intelligence, attention disorders, or general cognitive improvement.

By using Blink, you agree to the practices described here. If you don’t agree, please don’t use the app.

None. Blink has no account system, no sign-up form, no login, and no server that the app talks to for its core gameplay. There is no field anywhere in the app asking for your name, email, phone number, or any other personal information.

Every reaction-time score, level, rank, and setting you produce is generated and consumed entirely on your device. We — the developer — never receive it, store it on any server, or have any way to see it.

Blink stores the following locally, using standard on-device app storage:

This data is deleted the moment you tap Settings → Reset statistics, or the moment you uninstall the app — whichever comes first.

Blink is free to play and shows ads served by Google AdMob: a small static banner on menu screens, and an occasional full-screen ad between rounds. AdMob is the one part of Blink that does collect data — this happens through Google’s SDK, not code Blink itself wrote, and is governed by Google’s Privacy Policy and (for the EU/UK) Google’s Ads Data Processing Terms.

Data AdMob may process to serve and measure ads includes:

• Advertising identifiers (Android Advertising ID / Apple’s IDFA, where permitted)
• General device information (device model, OS version, language, screen size)
• Approximate location derived from IP address (not precise GPS location — Blink never requests location permission)
• Ad interaction data (impressions, clicks, viewability)

If you’d like exact figures for your build’s data practices, generate them from your own AdMob account and app configuration — the categories above describe what the SDK is capable of collecting, not a certified inventory.

Result and rank screens have a Share button. Tapping it hands your device’s own native share sheet a short line of text (your score and rank) — the same system dialog you’d get sharing a photo from any app. Blink doesn’t send this anywhere itself; where it goes is entirely up to which app or contact you pick in that share sheet.

Blink does not request access to your camera, microphone, contacts, photos, precise location, or files. The only device capability it uses beyond normal app storage is internet access, needed solely to request ads and (optionally) for AdMob’s own measurement — gameplay itself works fully offline.

Blink doesn’t knowingly collect personal information from anyone, including children — there’s simply nowhere in the app to enter any. That said, arcade-style reflex games like Blink can appeal to younger players, and ad networks have specific obligations around child-directed content (COPPA in the US, GDPR-K and similar in the EU/UK, and comparable rules elsewhere).

ISG — before launch, decide whether Blink is “directed to children” under these frameworks, configure AdMob’s child-directed treatment and ad-content filtering accordingly, and get that decision reviewed by counsel. Don’t rely on this paragraph as the compliance answer; it’s a pointer to the decision, not the decision itself.

Because Blink itself holds no account and no server-side data about you, most of what “access, correct, or delete my data” means elsewhere is already in your hands directly:

• Delete everything Blink stored: Settings → Reset statistics, or uninstall the app.
• Turn off ad personalization: your device’s ad settings — Android’s Settings → Privacy → Ads, or iOS’s Settings → Privacy & Security → Tracking / Apple Advertising.
• Opt out of Google’s ad personalization generally: adssettings.google.com.

If you’re in a jurisdiction that grants additional rights (GDPR, CCPA/CPRA, and similar), and you have a question specifically about data Google’s AdMob SDK processed, Google is the data processor/controller for that data — see their privacy policy linked in Section 4 for how to exercise those rights with them directly.

On-device data (Section 3) persists until you clear it or uninstall the app — Blink sets no automatic expiry, since it’s yours to keep as a personal training record for as long as you want it. Data AdMob processes is retained per Google’s own policies, not ours.

Your gameplay data lives in your device’s app-private storage, protected by your operating system’s own app sandboxing — the same protection every app on your phone relies on. Because it never transmits to a server we run, there’s no Blink-operated database to be breached.

Blink itself transfers no personal data internationally, having none to transfer. Ad requests and any data AdMob collects may be processed by Google on servers outside your country; Google’s own terms (linked in Section 4) cover the legal basis for that.

If this policy changes, we’ll update the effective date at the top of this page. For material changes — for example, if a future version adds accounts, a backend leaderboard, or new data collection — we intend to give more prominent notice before the change takes effect.
