Privacy Policy for Let's Scale

Effective date: October 11, 2026 · Last updated: October 16, 2026

Let's Scale is a mobile game made by Artem Svirinovskyi (“we”, “us”). It is available on the App Store and Google Play. This policy explains what data the game collects, why, who receives it, how long we keep it and how you can delete it.

The short version

You can play without an account. On first launch the game creates a random player ID so that the leaderboards work.
Other players see your nickname, country and scores in the leaderboards. The nickname and country are optional.
Signing in with Apple or Google is optional. It keeps your progress in the cloud, so you can continue on another device.
The game shows ads from Google AdMob. Personalised ads and your device's advertising identifier are used only with your permission.
“Remove ads” and “Support the developer” are optional one-time purchases. The App Store or Google Play handles the payment; we never see your card details.
We use Google Analytics for Firebase to see how the game is played. It doesn't receive your nickname, country or player ID.
You can delete your data in the game: Profile → Delete account (or Delete my data, if you haven't signed in). How to delete
We don't sell your personal data.

1. What data we collect

Created automatically

Data	When	Where it is stored	Why
Random player ID (Firebase user ID)	On first launch	Google Firebase Authentication	To link your leaderboard entry, results and cloud save to you, and to block fake scores
Total points and player number (“Player N”)	While you play	Google Cloud Firestore; visible to other players	Global and country leaderboards
Daily challenge result (percent and points) and weekly total	After you finish the daily challenge	Cloud Firestore; visible to other players	Daily and weekly leaderboards

Added by you (optional)

Data	When	Where it is stored	Why
Nickname, up to 14 characters	If you enter one in your profile	Cloud Firestore; visible to other players	Shown next to your results. Without a nickname you appear as “Player N”. Offensive nicknames are filtered out.
Country	If you choose one in your profile. The game doesn't detect your location.	Cloud Firestore; visible to other players	Country leaderboard and a flag next to your name
Profile photo	If you add one	Only on your device	Shown in your profile. It is never uploaded, and other players don't see it.

If you sign in with Apple or Google (optional)

Firebase Authentication links your Apple or Google account to your player ID. It stores:

your Apple or Google account ID;
the email address that Apple or Google gives us. With Apple it can be a private “Hide My Email” address;
with Google sign-in on Android, also the name and profile-picture link from your Google account (on iPhone, Google gives us only your email). We don't show them to other players.

If Apple shares your name on first sign-in, the game keeps it only on your device, to label your account in the profile.

Cloud save. While you're signed in, the game saves your progress in Cloud Firestore: level results and stars, collection cards, awards, daily challenge history and streak, mini-game records, the codes of your duels, your height and silhouette choice, the supporter crown, and game settings (nickname, country, units, language, colour, music). Only you can read your cloud save. If you sign out, the cloud save stays in your account. Without signing in, your progress stays only on your device.

Ads (Google AdMob)

The game is free and shows ads from Google AdMob: a full-screen ad between levels and mini-games (never during the daily challenge) and optional rewarded videos that you choose to watch for an in-game bonus.

The AdMob software in the game sends data directly to Google:

your IP address, which Google uses to estimate your approximate location;
device and app information, such as device model, OS version and app version;
ad data: which ads you saw and tapped;
performance and crash information about the ads;
your device's advertising identifier: on iPhone (IDFA) only if you allow tracking; on Android, the Advertising ID.

We don't send Google your nickname, email, player ID or progress. We ask Google only for ads suitable for a general audience (content rating “PG”). How Google uses data from apps: policies.google.com/technologies/partner-sites. Section 4 explains your choices.

Purchases: “Remove ads” and “Support the developer” (RevenueCat)

You can buy “Remove ads” once. It turns off full-screen ads; rewarded videos stay available if you want them. The App Store or Google Play handles the payment — we never see your card or payment details.

“Support the developer” is an optional one-time purchase in several amounts, and you can make it more than once. It doesn't unlock content or change the game. As a thank-you, a crown appears on your home screen and next to your name in the leaderboard, where other players see it. You can hide it from the leaderboard with the “Crown in leaderboard” switch in your profile.

To confirm and restore purchases, we use RevenueCat, Inc. The game sends RevenueCat your player ID. The store sends it the purchase details: product, date, price, currency and the country of your store account. We've turned off RevenueCat's automatic collection of device identifiers. If you sign in with the same Apple or Google account on another device, your purchases come with you.

Analytics (Google Analytics for Firebase)

To see which parts of the game work and which don't, the game sends Google Analytics for Firebase short reports about play: which screens you open, which levels and mini-games you start and finish, results in percent, settings you change (for example, sound on or off), ads shown or watched, and the “Remove ads” and “Support the developer” purchases.

Firebase adds an app-instance ID it creates, device model, OS and app version, language, approximate location (country or region, from the IP address) and session times.

Analytics doesn't receive your nickname, photo, chosen country, player ID, email or duel codes, and it doesn't use your advertising identifier. Where the law requires consent (EEA, UK, Switzerland), analytics works only if you agree in the consent form; without consent, the game sends nothing to Analytics.

Game Center (iPhone, optional)

If you're signed in to Game Center, the game sends Apple your achievements and two scores for the Game Center leaderboards: total points and daily streak. Apple handles this data under its privacy policy. The game doesn't read your Game Center ID or name.

Stored only on your device

settings: sound, music, vibration, units, language, reminders;
the profile photo and the name from Apple (see above);
your progress, if you haven't signed in;
the list of players whose names you've hidden in the leaderboards.

Result pictures. When you share a result, you can choose “Save Image” in the system share sheet. The game can only add pictures to your photo library; it never reads it.

Reminders. Reminders are local notifications that your device schedules, between 9:00 and 22:00 local time. No server is involved. You can turn them off in the game settings or in your device settings.

Duels. When you challenge a friend, the game stores the challenge in Cloud Firestore under a random 6-digit code: the set of pairs, your percent for each pair, the time and your player ID. Anyone signed in to the game who has the code can open it. When a friend accepts the challenge, their player ID, nickname and percent for each pair are added to it. The challenge is deleted once you've seen the result; if nobody accepts it, after 7 days; if it's accepted but you don't open the game, after 30 days. Deleting your account or your data in the profile also deletes the challenges your device or your cloud save remembers.

If you email us

We receive your email address and what you write. We use it only to answer you.

What we don't collect

Precise location, contacts, camera, microphone, contents of your photo library, health data, browsing history and payment card details. There is no chat: players can't send each other messages.

2. Why we use data and on what legal basis

Purpose	Data	Legal basis (EEA and UK)
Run the game: leaderboards, daily and weekly results, account, cloud save, purchase restore	Player ID, nickname, country, scores, results, account ID and email, cloud save, purchase details	Performance of a contract — providing the game you asked for
Fair play and security: blocking fake scores and abuse	Player ID, scores, time of each update	Legitimate interests
Personalised ads	Advertising identifier, ad data, approximate location	Your consent
Non-personalised ads that keep the game free	Ad data, approximate location, device information	Legitimate interests, within the choices you made in the consent form
Improve the game	Analytics data	Your consent in the EEA, UK and Switzerland; legitimate interests elsewhere
Answer your emails	Email address, message	Legitimate interests

We don't make automated decisions about you that have legal or similarly significant effects.

Google — Firebase Authentication and Cloud Firestore (account, leaderboards, results, cloud save), Google Analytics for Firebase (analytics), Google AdMob and the User Messaging Platform (ads and the consent form), Google Sign-In and Google Play (if you use them). Firebase works for us as a service provider. AdMob also uses data for Google's own purposes, as described in Google's policies: Google Privacy Policy, Firebase Privacy & Security.
RevenueCat, Inc. — confirms and restores the “Remove ads” and “Support the developer” purchases. RevenueCat Privacy Policy.
Apple — Sign in with Apple, App Store payments, Game Center and the tracking permission on iPhone. Apple Privacy Policy.
Other players — see your nickname, country, points, player number and daily and weekly results in the leaderboards.
Authorities — only if the law requires it.

We don't sell your personal data and don't give it to anyone else.

4. Ads, consent and tracking: your choices

Consent form (EEA, UK, Switzerland and other regions where required). Before any ad loads, the game shows Google's consent form. Until you make a choice, ads don't load. If you don't agree to personalised ads, you'll see non-personalised or limited ads. You can change your choice at any time: Settings → Ad privacy settings, or Profile → Privacy settings. These buttons appear where the law requires them.
Tracking on iPhone (App Tracking Transparency). iOS asks whether the game may track you — right before the first ad or on the second launch. Until you answer, the game asks only for non-personalised ads. If you allow tracking, Google may use your IDFA to show more relevant ads and measure them. If you don't, Google doesn't receive the IDFA, and you still see ads, just less relevant ones. To change it: iPhone Settings → Privacy & Security → Tracking.
Android. You can reset or delete your Advertising ID in your device settings (usually Settings → Privacy → Ads).
US state privacy laws. Under some US state laws, such as California's, personalised ads from Google may count as “sharing” personal data for targeted advertising. To opt out, use Privacy settings in the game where shown, turn off tracking on iPhone, or delete your Advertising ID on Android.

5. How long we keep data

Data	How long
Player ID, leaderboard entry, daily and weekly results, cloud save	Until you delete them in the game or ask us to
Account data from Apple or Google (account ID, email, name)	Until you delete your account
Purchase records at RevenueCat	As long as needed to restore your purchases and keep accounting records. We delete it on request.
Analytics data	Up to 14 months; then Google deletes it automatically
Ad data at Google	Under Google's policies
Your emails to us	Up to 12 months after we answer
Data on your device	Until you delete the game or your data

6. How to delete your account and data

This section explains how to delete your data in Let's Scale by Artem Svirinovskyi.

In the game, if you signed in with Apple or Google: Profile → Delete account. The game asks you to sign in once more to confirm it's you. Then it permanently deletes:

your cloud save;
your daily and weekly results for the days your device remembers — about the last two months;
your leaderboard entry, with the supporter crown;
your Firebase account (account ID, email, name);
your progress, nickname, country and photo on this device.

It also revokes Sign in with Apple.

In the game, if you haven't signed in: Profile → Delete my data. The game deletes your leaderboard entry, your daily and weekly results for about the last two months and your player ID, and starts over on this device.

If something goes wrong — for example, there's no internet — nothing is deleted, and you can try again. Uninstalling the game doesn't delete data on our servers. If you played without signing in and then reinstalled the game, it got a new player ID and can't delete data saved under the old one — write to us, and we'll delete it.

By email: write to support@vias.im from any address. Tell us your player name or number from the game, or the email you used to sign in. We'll delete your data within 30 days and reply to confirm.

What stays after deletion:

daily and weekly results that the game can't find from your device: those older than about two months, and those saved under an earlier player ID — for example, before you reinstalled the game or signed in to an account you already had. Each such entry keeps the nickname, country and “Player N” number you had then, the percent and points, and the random player ID. We don't delete them automatically. Write to support@vias.im with your player name or number, and we'll delete them within 30 days;
purchase records at RevenueCat — we delete them if you ask by email. Apple and Google keep their own purchase records under their policies;
empty technical records that contain only the random player ID, without a name or score. After deletion they can't be linked to you;
analytics data — it isn't linked to your account and is deleted automatically (section 5);
data that Google AdMob has collected — you can reset your advertising identifier in your device settings;
Game Center achievements and scores — you manage them in your Apple account.

If you find anything else left, write to us and we'll remove it.

7. Children

Let's Scale is for a general audience and isn't directed at children under 13 (or the minimum age in your country). The game doesn't ask for age. Ads are limited to the “PG” content rating. We don't knowingly collect personal data from children under 13. If you're a parent or guardian and think your child has given us personal data, write to support@vias.im or use Profile → Delete account, and we'll delete it.

8. Security

The game sends all data over encrypted connections (HTTPS/TLS). Firestore security rules let only you read your cloud save, and only you can change or delete your leaderboard entry and results. No system is perfectly secure, so we collect as little as the game needs.

9. International data transfers

Cloud Firestore keeps the leaderboards, results and cloud saves in the European Union (Google's “eur3” location). Firebase Authentication, Google Analytics, AdMob and RevenueCat may process data in the United States and other countries. Where the law requires it, these transfers rely on safeguards such as the EU Standard Contractual Clauses or the EU–US Data Privacy Framework.

10. Your rights

Depending on where you live — for example, under the GDPR, the UK GDPR or California's CCPA — you have the right to:

access your data and get a copy;
correct it — you can change your nickname and country in the profile at any time;
delete it (section 6);
object to or restrict processing;
withdraw consent at any time (section 4). This doesn't affect processing that happened before;
opt out of the “sale” or “sharing” of personal data for targeted advertising (section 4);
not be treated differently for using these rights.

To use them, write to support@vias.im. We'll answer within one month. To make sure the request is yours, we may ask for your player name or number. If you live in the EEA or the UK, you can also complain to your local data protection authority.

11. Changes to this policy

If we change how the game handles data, we'll update this policy and the “Last updated” date before the change reaches the game. For significant changes, we'll also tell you in the game or in the store listing.
