Privacy Policy

Last updated: September 2, 2026

This Privacy Policy explains how Hollowfall ("the Game", "we", "us", or "our") handles information when you use the Game.

The Game is developed and operated by Heorhii Tomiuk, based in Ukraine.

If you have any questions about this Privacy Policy or your personal data, you can contact us at playhollowfall@gmail.com.

1. Information We Process

The Game is designed to work offline and does not require an account to play.

If you choose to use the optional Cloud Save feature, we process the following information:

Email address

When you enable Cloud Save, you provide an email address.

We use this email address solely to:

authenticate your Cloud Save account using a one-time password (OTP);
associate your account with your saved game progress; and
allow you to identify which email address is currently linked to your Cloud Save.

We do not publicly display your email address to other players.

We do not use your email address for advertising or marketing.

Account information

When you authenticate using Supabase Auth, an account identifier (such as a unique user ID) is associated with your account.

This identifier is used to associate your authenticated account with your game progress.

Game-save data

If you use Cloud Save, we store the game data necessary to provide the Cloud Save feature.

This may include information such as your character progress, inventory, statistics, settings, and other game-state information contained in your save.

We do not intentionally collect information that is not necessary to provide the Game or its Cloud Save functionality.

2. Offline Gameplay

The Game can be played without creating an account or providing an email address.

When you play offline, your game progress may be stored locally on your device or browser.

Local game data is separate from your Cloud Save account.

If you clear your browser data, uninstall the Game, change devices, or otherwise remove locally stored data, your local progress may be lost if it has not been synchronized with Cloud Save.

3. How We Use Information

We use information for the following purposes:

to provide and maintain Cloud Save functionality;
to authenticate users who choose to use Cloud Save;
to associate saved game progress with the appropriate account;
to maintain and secure the Game and its infrastructure;
to detect, prevent, and investigate technical problems, abuse, fraud, or security incidents; and
to comply with applicable legal obligations.

We do not sell your personal information.

We do not use your email address for advertising or marketing.

4. Authentication and Service Providers

We use third-party infrastructure providers to operate the Game and provide Cloud Save functionality.

Supabase

We use Supabase for authentication and database services.

Supabase may process your email address, account information, authentication information, and Cloud Save data on our behalf as necessary to provide these services.

You can learn more about Supabase's privacy practices at:

https://supabase.com/privacy

Cloudflare

The Game is hosted and delivered using Cloudflare.

When you access the Game, Cloudflare may process technical information associated with requests to the Game, such as IP addresses and information contained in security or operational logs, as necessary to provide, secure, and operate its services.

You can learn more about Cloudflare's privacy practices at:

https://www.cloudflare.com/privacypolicy/

We do not use Cloudflare or Supabase to sell your personal information.

5. Cookies and Similar Technologies

The Game does not intentionally use advertising cookies or tracking technologies for targeted advertising.

The Game may use technologies necessary to provide authentication, security, or other functionality.

Your browser may also store Game data locally as part of the offline gameplay functionality.

If we introduce analytics, advertising, or other non-essential tracking technologies in the future, we will update this Privacy Policy and, where required, obtain the appropriate consent.

6. Legal Bases for Processing

Where the General Data Protection Regulation (GDPR) or similar data-protection laws apply, we process personal data using an appropriate legal basis under applicable law.

For Cloud Save, processing your email address and associated account information is generally necessary to provide the Cloud Save service you have requested.

We may also process information where necessary to comply with legal obligations, protect the security of the Game, prevent abuse, or pursue other legitimate interests permitted by applicable law.

Where consent is required by law, we will request it separately.

7. Data Retention

We retain your Cloud Save account information and associated game data for as long as necessary to provide the Cloud Save service, unless you request deletion or a longer retention period is required or permitted by applicable law.

Technical and security logs may be retained by our infrastructure providers for periods determined by their respective policies and operational requirements.

We may delete inactive accounts or Cloud Save data in the future. If we introduce an automatic deletion policy, we will describe the applicable retention period in an updated version of this Privacy Policy.

8. Deleting Your Data

You may request deletion of your Cloud Save account and associated personal data by contacting us at:

playhollowfall@gmail.com

Where technically and legally possible, we will delete the email address, account information, and associated Cloud Save data.

Some information may need to be retained where required by law or where necessary for legitimate security or legal purposes.

Deleting your Cloud Save account may permanently delete your cloud-stored game progress.

9. Your Privacy Rights

Depending on where you live and which laws apply to you, you may have rights regarding your personal data.

These may include the right to:

request access to your personal data;
request correction of inaccurate personal data;
request deletion of your personal data;
request restriction of certain processing;
object to certain processing;
request portability of your personal data where applicable; and
withdraw consent where processing is based on consent.

To exercise an applicable right, contact us at playhollowfall@gmail.com.

You may also have the right to lodge a complaint with the data-protection authority in your country or region.

10. International Data Transfers

Because the Game is available worldwide and uses third-party infrastructure providers, your information may be processed in countries other than the country in which you live.

Where applicable data-protection laws require safeguards for international transfers, we rely on appropriate mechanisms provided by applicable law and our service providers.

11. Children's Privacy

The Game is not intentionally designed to collect personal information from young children.

The Game does not require an email address or account to play offline.

If you are a parent or guardian and believe that a child has provided us with personal information in circumstances where this was not appropriate, please contact us at playhollowfall@gmail.com so that we can review and, where appropriate, delete the information.

12. Security

We take reasonable technical and organizational measures designed to protect information processed through the Game.

However, no internet transmission, computer system, or electronic storage system can be guaranteed to be completely secure.

You should also protect access to the email account you use for Cloud Save, since access to that email account may allow someone to authenticate as you.

13. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes to the Game, our services, applicable laws, or the way we process information.

When we make changes, we will update the "Last updated" date at the top of this Privacy Policy.

If we make material changes that require additional notice under applicable law, we will provide appropriate notice.
