Potion Pawn: Dark Alchemist

Effective Date: November 4, 2026 · Last updated: November 4, 2026

TL;DR — Your shop (gold, stock, day, upgrades and settings) is saved on your device in an encrypted file. The App shows rewarded ads only, and only when you choose to watch one; ads are served by Google AdMob. If the App crashes, a report goes to Firebase Crashlytics so we can fix it, and a few usage statistics (such as how many shop days players finish) go to Google Analytics for Firebase so we can improve the game. If you sign in to Google Play Games, a copy of your shop is kept in your Google account so you can carry it to another phone. MEDEV Studios runs no servers for the App and does not sell your data to anyone.

01

Introduction

MEDEV Studios ("we", "us", or "our") operates the Potion Pawn: Dark Alchemist mobile game (the "App", package com.medevstudios.potionpawn). This Privacy Policy explains what data the App handles, why, and the choices you have. It applies to version 1.0.0 of the App and later.

Potion Pawn: Dark Alchemist is a single-player potion shop game: you brew what customers ask for, haggle over the price with a hand of cards and keep the Inquisition from your door. The App needs no account and plays without an internet connection. It never asks for your email address, phone number, contacts, photos or location.

02

Data Stored on Your Device

We do NOT ask for or receive: email addresses, phone numbers, precise location, contacts or any other personally identifiable information. The Google services built into the App do collect some data, including your device's advertising ID, as described in Sections 03 to 06.

The App saves the following in its private storage on your device, in an encrypted file sealed against tampering, with a backup copy:

  • Your shop: the day, gold, gems, ingredients, upgrades and decor, your haggling deck, the recipes in your grimoire, your regulars and how far their stories have gone, the day's guild contracts, the debt paid so far and the guild rank
  • Achievements, the daily gift calendar and game statistics (such as potions brewed and customers served)
  • Settings: sound and music volume, language, battery saver and tutorial progress
  • Whether you play as a guest or signed in to Google Play Games, and how many rewarded ads you watched today (for the App's daily ad limits)

If Android backup is turned on for your device, Android may copy this save to your own Google account so it can be restored on a new device or after reinstalling the App. We cannot see these backups; you can turn backup off or delete it in your device's Google settings. Signed-in players can also carry their shop with cloud save (Section 06).

03

Advertising (Google AdMob)

The App shows rewarded video ads only, served by Google AdMob. An ad plays only when you tap an offer that says what it gives and choose to watch it: calling back a customer who walked out mid-haggle, doubling a good day's takings, another spin of Madame Zora's wheel, or a smuggler's crate when your shelves are bare. There are no banner ads and no interstitial ads, and you can play the whole game without ever watching an ad.

When an ad is requested or shown, Google AdMob may collect the following to deliver and measure ads and to prevent fraud:

  • Advertising ID (can be reset or deleted in your device settings)
  • Device type and operating system version
  • Approximate location derived from your IP address (not precise GPS)
  • How you interact with ads, and diagnostic data

You can opt out of ad personalization at any time in your device settings (Settings → Google → Ads, or Settings → Privacy → Ads on some devices).

Learn more: How Google uses information from sites or apps that use its services

EEA, UK and Switzerland: If you are located in the European Economic Area, the United Kingdom or Switzerland, the App asks for your consent through Google's User Messaging Platform before any ad is requested. A new player sees the form at the first night market, before the first ad can be offered; later launches check it again. You may choose non-personalized ads, and you can change or withdraw your choice at any time from Ad privacy in the App's Settings.

iOS: If the App is released for iPhone, it asks for permission to track through Apple's App Tracking Transparency prompt, after Google's consent form. Your device's advertising identifier is used only if you allow it; you can change this in your device's Settings.

04

Crash Reports (Firebase Crashlytics)

When the App crashes or runs into an error, it sends a report to Google's Firebase Crashlytics so we can find and fix the problem. A report contains:

  • The error and where in the App's code it happened
  • Device model, Android version and App version
  • Free memory and storage at the time of the crash
  • A random installation identifier created by Crashlytics
  • Two facts about the game session: the shop day and the language

Crash reports do not include your name, contact details or advertising ID. Google keeps them for up to 90 days. Crashlytics is used only to fix crashes and errors, not for analytics or advertising.

05

Usage Statistics (Google Analytics for Firebase)

The App sends a few usage statistics to Google Analytics for Firebase. We use them to see how players get on with the game, where they stop and which offers they take, so we can improve it. The App sends:

  • Game events: the first customer served (the end of the tutorial), a shop day closing (with the day number, the day's net takings, customers served and lost, and the guild rank), a rewarded ad finishing (with which offer it was), and each payment toward the old master's debt (with the total paid) and its last one
  • Information Firebase collects automatically: a random app instance identifier, when the App was first opened, sessions and time spent in the App, App version, device model, Android version, language, and the country or region derived from your IP address
  • Your device's advertising ID (unless you have deleted it in your device settings, or, in the EEA, UK and Switzerland, have not consented), and the ad impressions that Google AdMob reports for ads you chose to watch

Usage statistics do not include your name, contact details or the contents of your save. Google keeps data tied to the app instance identifier for no more than 14 months. Clearing the App's data or uninstalling the App resets that identifier.

EEA, UK and Switzerland: Usage statistics follow the choices you make in Google's consent form. Until you answer, and if you do not consent to storing and accessing information on your device, the App sends only limited signals without an app instance identifier or advertising ID. You can change your choices at any time from Ad privacy in the App's Settings.

06

Cloud Save (Google Play Games)

Cloud save is optional and available on Android. On your second day in the shop the App offers a choice between signing in with Google Play Games and playing as a guest; you can change it later from the account row in the App's Settings. While you are signed in, the App keeps a copy of your shop in Saved Games in your Google account, so you can carry it to another phone or keep it through a reinstall.

  • The copy is the same encrypted save that is kept on your device (see Section 02), with a short description (the day and your gold)
  • The App syncs it when you sign in or open the App, at the end of each shop day and when you leave the App
  • If the cloud copy is further along than the shop on your phone, the App asks which one to keep; nothing is overwritten without your choice

The App reads your Play Games display name only to show it in Settings. The cloud copy is stored by Google; we cannot see it. You can delete it from the Google Play Games app's settings (delete the game's data).

Third-Party Services Summary

The following third-party services are integrated into the App:

  • Google AdMob — Rewarded ads you choose to watch · Privacy Policy

08

Virtual Currency & Rewards

Gold, gems, ingredients and other rewards in the App are earned through play, the daily gift, guild contracts, Madame Zora's wheel and rewarded ads. They have no real-world monetary value and cannot be exchanged for cash.

The App has no in-app purchases. If in-app purchases are ever added, all transactions will be processed through Google Play, and this policy will be updated first.

09

Children's Privacy

Potion Pawn: Dark Alchemist is not directed at children under 13 and does not knowingly collect personal information from them. Its story includes poisons, contraband and raids by the Inquisition. The App does not ask any user for personal information and does not require registration.

Because the App is not directed at children, its ad requests are not tagged for child-directed treatment.

If you believe a child has provided personal information through the App, please contact us at info@medevstudios.com and we will help remove it.

10

Your Rights & Choices

Depending on where you live, you may have rights under the GDPR, the UK GDPR, the CCPA, KVKK or similar laws:

  • Delete your progress — Use Erase save & start over in the App's Settings, clear the App's data in your device's app settings, or uninstall the App; if Android backup is on, also delete the App's backup in your device's Google settings, and if you use cloud save, the cloud copy (below)
  • Ads — Change your consent from Ad privacy in the App's Settings (EEA, UK and Switzerland); reset or delete your advertising ID and opt out of personalized ads in your device settings
  • Usage statistics — Change your consent from Ad privacy in the App's Settings (EEA, UK and Switzerland); clearing the App's data or uninstalling the App resets its app instance identifier
  • Cloud save — Optional: it is used only while you are signed in to Google Play Games. Sign out from the App's Settings, and delete the cloud copy from the Google Play Games app's settings (delete the game's data)
  • Request information — Contact us about any data processing related to the App

We do not keep personal data on our own servers, so there is no account for us to delete. Your game data lives on your device, where you control it. Requests about data held by the Google services above are best directed to Google; we will gladly help.

Turkish Residents (KVKK): Under the Turkish Personal Data Protection Law (Law No. 6698), you have the right to learn whether your personal data is processed, to request its correction or deletion, and to object to processing. Contact us to exercise these rights.

11

Data Security

Your save is encrypted and sealed on your device, inside Android's app sandbox. The App only exchanges data over the internet when:

  • Google AdMob loads and shows an ad you chose to watch, or Google's consent form is shown
  • A crash or error report is sent to Firebase Crashlytics
  • Usage statistics are sent to Google Analytics for Firebase
  • Your shop is synced with Google Play Games, if you are signed in
  • Google Play shows the in-app review prompt

These connections are encrypted in transit using HTTPS/TLS.

12

Changes to This Policy

We may update this Privacy Policy as the App evolves. Changes are posted on this page with an updated "Last updated" date, and significant changes are also noted in the App's release notes.
