Delete Your HyperCastle Data

How to request deletion

1. Open HyperCastle on your device and go to Settings → About to find your Player ID (a pseudonymous UUID or your Google Play Games player identifier). Copy it.
2. Email [email protected] with the subject line Delete my HyperCastle data. Include your Player ID in the body of the email.
3. We will confirm receipt within 3 business days and complete the deletion within 30 days, as required by GDPR Art. 12(3).
4. If you want your local device data gone too, uninstall HyperCastle. Uninstalling Android apps clears their local storage.

What gets deleted

We remove everything tied to your Player ID from our Hetzner-hosted backend:

• Your pseudonymous Player ID record
• Gold balance and aggregate lifetime counters (earned, bought, spent)
• Gold transaction log (amounts, types, sources, timestamps)
• In-game inventory (purchased store items and their quantities)
• Cross-game linkage associated with the same Player ID

What is retained and why

Some records are held by third parties or required for legal reasons. They are outside our direct control:

• Google Play purchase receipts — retained by Google under their own policy for tax, refund, and fraud-prevention purposes. Manage at play.google.com/store/account.
• Google Play Games profile (leaderboard scores, achievements) — tied to your Google account, not to us. Manage at myaccount.google.com/data-and-privacy.
• Google Play Console crash reports — retained by Google for up to 180 days. We do not control this retention period.
• Server logs on our Hetzner backend — IP addresses and request metadata are retained for up to 30 days for security and troubleshooting, then purged automatically.
• Anonymised analytics aggregates — if your data was included in any aggregated totals before deletion, we retain the aggregates because they no longer identify you.

Account deletion

HyperCastle does not require an account to play. Deleting your data therefore removes the pseudonymous player record rather than an account. If you also want to sign out of Google Play Games, do so from inside Android Settings or the Google Play Games app.
