Privacy Policy

This Privacy Policy explains how Regulus ("we", "us") collects, uses, and shares information when you play Arcane Spire (the "Game"). By playing the Game you agree to this Policy. If you disagree, please do not use the Game.

1. Who we are

Arcane Spire is developed and operated by Regulus. For any privacy question or request, contact us at alex@regulus.io.

2. Information we collect

Game progress (on your device)

Your run history, currencies, upgrades, and settings are stored locally on your device. This data stays on the device and is not transmitted to us unless you sign in (below).

Account (optional)

If you choose to sign in, Firebase Authentication (Google) processes your sign-in provider (e.g. Google, Apple, or email), your email address, and a unique account identifier so we can operate your account and, where offered, sync progress. You can play the entire Game without signing in.

Leaderboard

If you submit a score, your chosen display name and your best wave reached are stored in our Firebase backend so scores can be ranked and shown to other players. Do not use personal information as your display name.

Advertising

Optional rewarded ads are served by Google AdMob, which may process device and advertising identifiers to serve and measure ads. In the EEA, UK, and Switzerland you are asked for consent first through Google's consent flow, and you can change your choice at any time via Privacy Options in the Game's settings.

Purchases

In-app purchases are processed by the Apple App Store or Google Play. We receive a purchase receipt/confirmation to deliver your items — we never receive or store your card or full payment details.

3. How we use information

• To run the Game and save your progress.
• To operate your optional account and the online leaderboard.
• To deliver and measure optional ads, subject to your consent where required.
• To deliver items you purchase and prevent duplicate or fraudulent grants.
• To diagnose crashes and keep the Game stable and secure.

4. Sharing and third-party services

We do not sell your personal information. We share limited data with service providers that operate parts of the Game:

• Google Firebase — authentication, database/leaderboard, and app-integrity checks (privacy).
• Google AdMob — rewarded advertising (how Google uses data).
• Apple App Store / Google Play — payment processing and receipts.

5. Children

The Game is not directed to children under 13 (or the minimum age of digital consent in your country). We do not knowingly collect personal information from children. If you believe a child has provided us personal information, contact us and we will delete it.

6. Data retention

On-device data persists until you delete the app or clear its data. Account and leaderboard data is retained while your account is active; contact us to have your account and associated leaderboard entry deleted.

7. Your rights

Depending on where you live, you may have the right to access, correct, delete, or export your personal information, and to withdraw consent for ads. To exercise any right, email alex@regulus.io. You can also decline or reset ad personalization through your device settings and the in-Game Privacy Options.

8. International transfers

Our providers (Google, Apple) may process data in countries other than yours, including the United States, under appropriate safeguards.

9. Security

We use reasonable technical and organizational measures to protect information. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

10. Changes to this Policy

We may update this Policy from time to time. Material changes will be reflected by the "Last updated" date above and, where appropriate, announced in the Game.
