S TIER
Privacy
What S TIER knows about you, and what it never will.
Last updated: November 8, 2026
On your iPhone, and nowhere else
Health, Screen Time, location and motion are read and judged on your iPhone. Never sent.
On the Leaderboard, the bare minimum
Your username, XP excluding Screen Time, rank, coin and trial records.
Never
No ads, no trackers, no analytics, no data sales.
Always yours
Delete your account in two taps, right from the app. It's immediate.
Who is responsible
S TIER is published by GolemX, the sole proprietorship of Adem Laurent, based in France. GolemX is the controller of the data described here.
For any question about your data, or to exercise your rights:
contact@golemx.frWhat stays on your iPhone
Everything that proves your quests is read and judged on your iPhone. This data is never sent: not to us, not to anyone.
Health (Apple HealthKit)
With your permission, S TIER reads your steps, walking distance, flights climbed, exercise minutes, active calories, workouts, sleep, resting heart rate and VO2 max. The app only reads: it never writes anything to Health. This data is never used for advertising and is never stored in iCloud by S TIER.
Screen Time
Apple never gives S TIER the list of your apps or your usage times: the app only receives a signal when a threshold is crossed, and a view that only your iPhone can read. None of it leaves your iPhone, and Screen Time quests don't count toward the XP sent to the Leaderboard.
Location
Only if you choose a gym or a library, and during the endurance trial (GPS). Your places' coordinates stay on your iPhone; iOS detects when you arrive.
Motion
Your iPhone recognizes walking, running and cycling, to prove your quests without a watch.
Everything else
- Your onboarding answers, your progress (XP, proofs, streaks, trials) and your settings.
- Notifications: they're scheduled on your iPhone.
- Photos: if you save your rank-up video, the app adds it to your library. It never reads your photos.
What goes to the Leaderboard
The Leaderboard is the only place where data leaves your iPhone. Here is the complete list:
Other players see your username, XP, rank, coin, records, best place, public titles and Founder number. This data is processed because the Leaderboard is part of the game you use (performance of the service), and for moderation and fraud prevention (legitimate interest).
Like any web server, our host processes your IP address to route the connection. We don't store it.
Hosting and partners
- Cloudflare hosts the Leaderboard server and its database, stored in the European Union. Cloudflare acts on our behalf, under a GDPR-compliant agreement.
- Apple handles payments and subscriptions. We never see your payment details; Apple is responsible for its own processing.
- That's all. No analytics, no ad networks, no trackers, no data sales.
How long
- Your Leaderboard account, scores and titles: as long as your account exists.
- When you delete your account, everything is erased immediately: username, scores, titles, player card, reports.
- One exception: the Founder number and the Apple purchase identifier that earned it are kept, with no link to your username. They prevent one purchase from getting two numbers, and let you recover your token if you come back.
- Data on your iPhone is removed when you delete your account or the app.
Your rights
You can access, correct, delete or export your data, or object to its processing, at any time.
- Delete your account: in the app, Profile, Privacy, Delete my account. It's immediate.
- Change your username: in the app, Profile, tap your name.
- Revoke access: iPhone Settings, Health, Screen Time or Privacy. The related quests will no longer be proven.
- Anything else: write to us, we reply within one month.
If you believe your rights aren't respected, you can lodge a complaint with your data protection authority (in France, the CNIL: cnil.fr).
Younger users
S TIER is not intended for children under 13. If local law requires it (in France, under 15), ask a parent's permission before joining the Leaderboard.
Security
Exchanges with the server are encrypted (HTTPS). There's no password to steal: your account is a random identifier kept in your iPhone's keychain. And the best protection is the simplest: we only collect what the Leaderboard strictly needs.
Changes
If this policy changes in a significant way, the app will let you know. Last updated: November 8, 2026.
