Samarkand has no account system and no server of its own. Your progress — souls collected, unlocked mutations, settings — is saved locally, in your browser or on your device, and never transmitted anywhere. The one exception is the Android build's optional rewarded ad: choosing to watch one hands a small amount of data to Google, described below.
03
What Samarkand stores, and where
04
Run and meta-progression (souls, unlocked mutations, best runs) — saved in your browser's localStorage on Web, or in local app storage on Android.
05
Settings — language, volume, and other preferences — stored the same way.
06
No analytics, no accounts
07
Samarkand does not use analytics or crash reporting, and has no account or sign-in system. Nothing about your play is ever collected or sent anywhere by the game itself.
08
Ads on Android
09
On Android, dying offers a choice: watch a short rewarded video ad to revive at half health, once per run, or decline and accept the death. This is entirely optional and never appears unless you choose to see it.
10
The ad itself is served by Google's AdMob. Showing it involves your device talking to Google — an advertising identifier, general device information, and approximate location may be shared with Google and its ad partners for ad delivery and measurement, under Google's own privacy policy (policies.google.com/privacy) and, for the ad-consent flow specifically, its UMP terms (developers.google.com/admob/ump/android/quick-start). Where required (the EEA, UK, and similar), the app asks for your consent to this before any ad loads. Declining the offer, or declining consent, changes nothing else about the game — the run continues, you just don't get the revive.
11
The Web build has no ads, no AdMob, and no consent prompt; the exception above is Android-only.
12
In-game statistics
13
The live combat statistics and end-of-run summary (damage dealt, DPS, rooms cleared, and similar figures) are calculated and shown entirely on your own device, for your own reference. None of it is transmitted anywhere.
14
Deleting your data
15
Clearing your browser's site data for Samarkand (Web) or uninstalling the app (Android) removes all locally-stored progress. This is permanent and cannot be undone, since there is no server copy to restore from.
16
Children's privacy
17
Samarkand is not directed at children and does not knowingly collect personal information from anyone. The game itself collects nothing at all; the Android build's ads are explicitly configured as not child-directed and rated for a general/teen audience, and are never shown to satisfy a legal requirement — they are always the player's own choice.
