Privacy Policy (MINI THIEF)

1. Overview
MINI THIEF ("the Game") respects your privacy and complies with applicable laws. The Game is a **single-device
game with no account and no login**. Nothing about your play is sent anywhere.
When you play on the web, one anonymous signal is sent so the game can show how
many players are online and how many runs have been started (section 3-2).
Played offline, not even that is sent.
2. Personal data we collect
The Game does not collect, store or transmit any personal data.
- Name, email, phone number, date of birth: not collected
- Location, contacts, photos, microphone, camera: not accessed
- Advertising identifiers (ADID/IDFA): not collected
- Payment information: not collected (the Game has no purchases)
Exception — world ranking (optional): only if you choose a nickname and join the world ranking do we process the items in section 3-3. If you do not join, nothing is collected, exactly as stated above.
3. Data stored on your device
To remember your preferences, the Game stores only the following values in your
browser/device local storage (localStorage). They never leave your device and can be removed at
any time by clearing browser data or uninstalling the app.
| Key | Content | Purpose |
|---|---|---|
minithief.lang | Selected language (one of 12) | Keep your language choice |
minithief.muted | Sound on/off | Keep your sound choice |
minithief.progress | Unlocked levels, best times, stars, loot and daily missions | Keep your progress |
minithief.custom | Levels you built or opened from a link | Keep your own levels |
minithief.compete | Daily challenge results and streak | Keep your streak |
minithief.sid (session) | Temporary number for the live counter, dropped when the tab closes | Avoid double counting |
minithief.visited (session) | Marks that this tab was already counted as a visit, dropped when the tab closes | Avoid counting a visit twice |
minithief.reminder | Daily reminder on/off and time (Android app) | Keep the reminder setting |
minithief.lb | Only if you joined the world ranking: random player id, secret token, nickname | Post ranking records |
minithief.outfitsSeen | The outfit tier already seen in the wardrobe | Show new outfits |
Language files: on the web, choosing a language other than Korean or English
downloads that language's text file from this site - an ordinary file request,
like loading a picture. Nothing about you is sent with it. The Android app
already contains every language and downloads nothing.
3-2. Counting players online (web only)
So the game can show "N playing now · N runs so far", and only when it runs on
the web, the following is sent. **It is not personal data: it identifies nobody
and cannot be joined to anything else.**
| Sent | What it is | Kept for |
|---|---|---|
| Session number | 16 random characters your browser tab invents for itself and forgets when it closes (sessionStorage) | deleted 2 minutes after the last signal |
| Event | either ping (still here) or play (a run started) | added to a total only |
| Visit | sent once when a page of this site or the game is first opened in a tab (the same session number as above) | the session number is kept 24 hours so a reload is not counted twice; the visit only adds to a total |
- Never stored: IP address, cookies, device or browser details, location,
advertising identifiers, your progress, which level you played, or any other
identifier.
- The result is a single running total. No per-person history exists or can
be reconstructed.
- Processed on Cloudflare (United States / global edge). The only stored values are the totals
and the session numbers above.
- Offline play (the installed app, a local file, a local server) sends
nothing at all.
- If the signal is blocked or fails, the game plays exactly the same; only the
counter is hidden.
3-3. World ranking (optional, added 2026-10-05)
Only if you choose a nickname and join on the game's "World ranking" screen, we process:
| Item | What | Purpose | Kept |
|---|---|---|---|
| Nickname | The 2-16 character name you chose and a random 4-digit tag | Show the ranking | Until you delete it |
| Player id and token | A random id made by the server; the secret token is stored only as a hash | Tell your records apart | Until you delete it |
| Clear records | Level, date (daily challenge), time, hints used, the moves you made, game build | Ranking, and cheat checks (the server replays the moves) | Individual runs 120 days; your best per board until you delete it |
- Not collected: email, phone number, device identifiers, location, advertising ids. Your IP address is used only briefly in server memory to stop request floods and is never stored.
- Processors and transfer abroad: the ranking server and database are run by Railway Corporation (USA); requests pass through Cloudflare, Inc. (USA). The items above are sent over the network when you post a record and kept for the periods above.
- Deletion: "Delete my ranking data" on the world ranking screen removes your nickname and every record from the server immediately. You can also ask by email.
- Step-by-step deletion page: https://minithiefgame.com/legal/delete-en
- The ranking shows only nickname, tag, time and whether hints were used, and it is public.
4. Third parties
Because no personal data is collected, nothing is shared with or processed by
third parties. The Game contains **no analytics SDK (no Google Analytics or
similar), no advertising SDK and no crash-reporting SDK.** The counter in
section 3-2 runs only on our own Cloudflare infrastructure and is shared with
nobody.
Only for the world ranking (section 3-3): storing and processing those records is entrusted to Railway Corporation (server and database hosting, USA) and Cloudflare, Inc. (proxy, USA).
5. Children's privacy
The Game collects no personal data from any user, including children under 14.
Children under 14 may not join the world ranking (section 3-3). The join screen asks you to confirm you are 14 or older, and records found to belong to a child under 14 are deleted immediately.
6. Your rights
As no personal data is held, there is no data to access, correct or delete.
Locally stored preferences can be removed by the user at any time.
If you joined the world ranking (section 3-3), you can view, correct (change your nickname) or delete your data in the game ("Delete my ranking data") or by email, and we act on it without delay.
