Sky Islands · last updated 27 September 2026
The short version: Sky Islands has no accounts, no ads, no analytics and no tracking. Your game progress stays on your phone. If you choose to post a score, the leaderboard stores the pilot name you typed, your score and a recording of that flight, tied to a random ID the app made up. Nothing is sold or shared.
Who we are
Sky Islands is made by Luma Tech Solutions in the United Kingdom, which is the data controller for the leaderboard. Contact: hello@lumatechsolutions.co.uk.
Stored only on your phone
Your gold, best score, unlocked planes and island skins, redeemed codes, the pilot name you last used and a random player ID are saved inside the app on your device. They are not backed up to us, and deleting the app deletes them.
Sent to our leaderboard server
When you tap “Post score” on the game-over card, the app sends:
- the random player ID (it is not linked to your Apple ID, device ID, email or phone number),
- the pilot name you typed (up to 16 characters),
- that run’s gold, islands found, landings and distance,
- the date of the daily course and a recording of your flight path (position and altitude ten times a second), so the day’s best runs can fly beside other players as ghosts.
Your pilot name, scores and flight path are shown publicly to other players on the leaderboard and as ghosts. Please don’t use your real full name. Names that break our blocklist are shown as “Pilot”.
When you take off, the app asks the server for the day’s best ghost runs and includes your random player ID so your own best run can be returned too. Nothing else is sent. If the server can’t be reached, the game plays normally offline.
Like any website, our server sees the IP address of each request. We use it briefly in memory to limit how often scores can be posted and it may appear in short-lived web server logs. It is not stored in the leaderboard database.
Why, and for how long
We use this data only to run the leaderboard and ghost races (our legitimate interest in providing the feature you asked for by posting). Leaderboard entries are kept while the game is running. Daily-course runs may be removed once they are no longer shown.
Where it is kept
On a server we operate, hosted by Hetzner Online GmbH. No other company receives the data.
Your rights
You can ask us to see, correct or delete your leaderboard entries by emailing hello@lumatechsolutions.co.uk with your pilot name and a recent score so we can find them. You can also complain to the UK Information Commissioner’s Office (ico.org.uk).
Children
Sky Islands is suitable for all ages. Posting a score is optional and asks only for a nickname. We don’t knowingly collect personal information from children; if you think a child has posted identifying information as a pilot name, email us and we will remove it.
Changes
If this policy changes, the new version will be posted here with a new date.
