Privacy Policy
What stays on your device
Your scores, bests, streaks, level progress and settings are stored locally on your iPhone. None of this is uploaded by us. Deleting the app deletes this data permanently.
Game Center (global leaderboards)
Leaderboards are provided by Apple's Game Center. If you are signed in to Game Center, your scores are submitted to Apple together with your Game Center player identity, and Apple shows them on the leaderboard under your Game Center nickname. We never receive your name, email, or Apple ID — the app only reads the leaderboard entries Apple exposes (nicknames and scores) in order to display them.
Game Center is governed by Apple's Privacy Policy. You can play without Game Center; leaderboards are simply unavailable then.
Notifications
If you allow notifications, the app schedules local reminders (for example, that a new daily board is available). These are created and delivered entirely on your device — there is no push server and nothing is sent to us. You can disable them any time in Settings.
Song rounds are fetched from our game server (trackattack.mehro.ch). Requests are ordinary HTTPS calls used only to serve the round; we keep no per-user logs and no profiles.
Song previews are official 30-second clips provided via Apple, streamed on demand and never stored on your device or our servers.
My Music mode reads your Apple Music library on your device. To play a snippet of each quiz song, that song's title is looked up via Apple's public iTunes preview service (the same previews the rest of the app uses) — your library is never sent to our servers, and the wrong-answer choices are drawn from your own library with no lookup at all.
Playlists you create in Tack are written to your own Apple Music library when you tap Save, and nowhere else. Only songs already in your library can be added; the app never searches the Apple Music catalogue.
No ads, no analytics, no accounts, no tracking. Leaderboards are Game Center, operated by Apple under Apple's privacy policy.
Sharing a score
Tapping Share hands a line of text to iOS's own share sheet. You choose where it goes; the app never sends it anywhere, and we never see it or know that you shared. The text ends with a link to our App Store page.
That link carries a marker (ct=share) telling Apple the visit came from
a shared score rather than from search. Apple reports this back to us only as
aggregate counts — how many installs came from shares in total. It is
not tied to you, to the person you sent it to, or to any device.
Ratings
The app may occasionally ask you to rate it. That prompt is presented by iOS itself, the rating goes to Apple, and the app is not told what you chose or whether you responded at all.
What we don't do
- No accounts, and no collection of your name, email, or contacts.
- No third-party analytics SDKs.
- No selling of data — we have nothing to sell.
- No servers of our own. Nothing you do in the app is uploaded to us.
- No advertising SDKs of any kind.
Children
The app is suitable for all ages and collects no personal data from anyone, including children.
Changes
If a future version changes any of the above, this page will be updated before that version ships, and the App Store privacy label will be kept in sync.
