HeartShard

Privacy Policy

Version 2026-11-03 · Last updated: 3 November 2026

In short: we keep only what we need to run the game. We only take your e-mail address and a one-way hash of your password if you make your account permanent. The data lives on a server in Germany (Nuremberg, EU); an encrypted copy of the backups is in Finland (Helsinki, EU). We show no ads in the game, never sell your data and use no tracking tools or ad pixels; we measure whether our ads work only by the campaign label in the link and by totals. You can delete your account from inside the game.

1. Who we are

HeartShard is a browser game developed and run by an independent developer ("we", "us"). We are the data controller under the EU General Data Protection Regulation ("GDPR") and the Turkish Personal Data Protection Law No. 6698 ("KVKK"). For any question or request: support@heartshard.com.

2. What we process

3. What stays on your device

We use no cookies. Your browser's local storage keeps your session token, the character you played last and your game settings, and your e-mail address if you choose "Remember me". If you choose to, your password is kept only by your browser's own password manager; we never write it to local storage. All of the game's files, fonts included, come from our own server. The one exception is Sign in with Google: its button is loaded from Google's servers (accounts.google.com) only on the start screen and in the form that saves a guest account; Google then processes your IP address and browser details under its own privacy policy and may use its own cookies. Nowhere else in the game does a request go to another company's servers. We use no advertising, analytics or tracking services: there is no ad platform pixel or tag (such as Meta, Google or TikTok) in the game, and we take no device fingerprint. The campaign label of a link is not written to your device.

4. Why we process it (legal bases)

We do not use your data for marketing and do no processing that relies on consent.

5. Where the data is kept, and transfers

The game's server and database run on a server we rent in Hetzner's Nuremberg (Germany, EU) data centre. Hetzner hosts it for us and may not use your data for its own purposes. An encrypted copy of the nightly backups is kept in a storage space in Hetzner's Helsinki (Finland, EU) data centre; only we hold its key. For players in Türkiye this is a transfer abroad, made under the conditions of KVKK Art. 9 and only as far as needed to provide the service.

If you sign in with Google, the sign-in itself is run by Google LLC (USA) under its own privacy policy, as an independent controller for it; it passes us only the two items in section 2. We send Google none of your game data.

We never sell your data or share it with anyone for advertising. We may share it with the authorities only when the law requires it.

Sending e-mail: password reset e-mails are sent through the Google Workspace account of the heartshard.com domain. Google is our processor for this: it handles your e-mail address and the e-mail's content only to deliver the e-mail and may not use them for its own purposes. Google's servers may be outside the EU and Türkiye, so this is a transfer abroad, made under the conditions of KVKK Art. 9 and only as far as needed to deliver the e-mail.

6. How long we keep it

7. Security

Connections are encrypted with HTTPS. Passwords are stored as Argon2 hashes and session tokens as SHA-256 hashes; the IP hash in login records is made with a secret key held on the server. The off-site backup copy is encrypted. The database is not reachable from the internet; only the authorised operator can access the server, with a key. No system is perfectly secure; if a data breach happens we will inform you and the competent authority as the law requires.

8. Age limit

Permanent accounts are for players aged 16 and over; we ask for your year of birth when you sign up, and nobody under 16 can create a permanent account. Playing as a guest or with Google also confirms that you are 16 or older. If we learn that we hold data of someone under 16, we delete that account.

9. Your rights

You have the right to access your data, have it corrected, have it deleted, restrict its processing, receive it in a portable format, and object to processing based on legitimate interest (GDPR Art. 15–21). Under KVKK Art. 11 you may also ask whether and how your data is processed, who it was transferred to, have third parties told of corrections or deletions, object to a result reached solely by automated analysis, and claim compensation for unlawful processing.

Write to support@heartshard.com from the e-mail address of your account; we answer within 30 days. If you are not satisfied, you may complain to the data protection authority of the EU country where you live, or to the Turkish Personal Data Protection Authority (KVKK).

10. Changes

If we change this policy we publish the new version on this page and update its version date. Permanent accounts are shown the new version and asked to accept it at their next login.
